Las Vegas Shooting 1-Oct-2017 - An acoustic analysis and personal observations

Entrance to the Paddock Hotel Room

See the change log at the end of this document for a complete revision history.


First and foremost, my heart goes out to everyone affected by this senseless waste of human life. If you were one of the many people that were present at the Route 91 Harvest Festival in Las Vegas on the night of October 1st, 2017, then know that this work is dedicated largely to you.

Unlike some others who are capitalizing on this event, i am not seeking any monetary gain for my work. I decided to do this research because it bothers me deeply that so many of the witnesses and the public at large are being given answers that, in my opinion, are sometimes deeply flawed and therefore i'd like to make an attempt to provide some evidence-based answers that are more accurate than some of the garbage floating around on the web.

Anyone who has researched the Vegas Route 91 Harvest Festival mass-shooting is likely to have heard claims from several witnesses who have stated, to varying degrees of certainty, that multiple gunmen were acting in concert with, or in place of the primary suspect, Stephen Craig Paddock, and it is this facet of the shooting which is the focus of this investigation. To be clear, the primary scope of this analysis was purposely limited to determining whether or not more than one gunman targeted the Route 91 Harvest Festival venue specifically, as well as to determine the approximate location of the shooter or shooters.

Let me be clear about how the term "multiple gunmen" is used here. As many others, i have also come across several reports of multiple gunmen targeting the venue as well as shooting incidents at various other locations in Las Vegas on the day of the shooting, including at the Bellagio, Caesars Palace, Planet Hollywood, the Tropicana, Hooters and others. While many of us are well aware of how dishonest and corrupt the mainstream media is, we must also account for the fact that it is sometimes the earliest news reports of an event which are filtered the least and therefore most revealing and in this case we have available both the news footage and the raw police scanner audio which was recorded live as this event unfolded.

Upon listening to the police recordings it becomes apparent that for each report of shootings at the aforementioned hotels, strike teams were quickly deployed to investigate those reports and in every case the allegations were unsubstantiated. Subsequent evidence, or lack thereof (few if any corroborating witnesses), confirm this. For example, regarding the alleged shooting at Hooters and reports of bodies being carried out, it appears this location was used as a staging area for emergency vehicles and victims of the Harvest Festival shooting. I am not certain of this, but i think this is a likely explanation according to the evidence i have examined. That said, again, my primary focus here is whether more than one gunman targeted the Route 91 Harvest Festival specifically and not whether there were simultaneous shootings elsewhere.

Perhaps many are aware of the acoustic analysis of the Harvest Festival shooting preformed by Mike Adams of Natural News in which he claims to have proven that there was indeed a second gunman targeting the concert venue. Adams stated in his video that he performed a "forensic spectral analysis" of audio samples recorded by witnesses in order to reach his conclusion. He further stated that the entire process consumed only about three hours of his time and i honestly have to shake my head and wonder what kind of "forensic spectral analysis" can be preformed in roughly three hours during a Sunday afternoon. To my knowledge, Mike has not followed up on his initial findings in order to accurately locate the second shooter he claims existed, even though he stated that doing so would be rather trivial. Given the scope of this tragedy and the number of people affected, both directly and indirectly, i find this incredibly irresponsible. (for more on Adams, see Mike Adams, an Alex 'Bullshit' Jones wannabe)

I think it is also irresponsible for Mike to promote what he himself admits is an unfinished analysis, across multiple high-traffic websites including YouTube, Veterans Today, Shooting News and Natural News (his own website), with seemingly more regard for how many views, 'clicks' and 'likes' he can acquire rather than seriously consider how such information may negatively impact the victims of this event, their families and the public in general if it is incorrect, as i believe my own research demonstrates. His clickbait titled YouTube video, Forensic acoustic proof of SECOND shooter in the Las Vegas massacre, had received over one million views as of this writing before it was removed and he continued to capitalize upon this massacre with several follow-up videos including another titled, The public astonished to discover this PROOF of a second Las Vegas shooter. In fact, as i think the evidence presented here clearly dictates, not only did Adams fail to prove there was a second shooter, he also neglected to adequately explain or publish the math and methods he used to reach his conclusions and therefore his hypothesis cannot be considered to be anything resembling science.

There are many victims of this slaughter and i'm sure that those left alive to grieve are desperate for answers, especially with regard to the motive of Stephan Paddock. When these traumatized people come across a half-baked 'analysis' alleging a second gunman without offering any hard evidence to back the claim, i think they are being victimized even further. If there was more than one gunman, fine, but there must be evidence to support such a conclusion. That said, i must credit Adams for inspiring me to pick up the ball that he prematurely dropped and attempt to carry it to its logical conclusion which is to determine if there were multiple shooters and, if so, their approximate locations.

After watching and listening to many of the videos recorded by eyewitnesses, i was also initially quite certain there was more than one shooter because i thought i clearly heard overlapping gunfire as well as very different tones of gunfire. The possibility of a second shooter did not surprise me in the least. As a matter of fact, i had expected to confirm Adams' claim of a second shooter. I am also quite aware of the bigger picture here and how events like this are often manufactured to be used for political purposes.

In order to confirm or refute the multiple shooter theory, i needed to determine the specific locations near the concert venue where several witness recorded their videos so i could then plot those locations on a map using reference points from their videos. The locations of the witnesses, in conjunction with the audio they recorded, would then make it possible to calculate the difference between the sounds of bullet impacts or supersonic booms and the sound of the muzzle reports. This delay can then be used to determine whether there were multiple gunmen, as well as the approximate locations of the gunmen once several witness recordings from different positions are analyzed. If this sounds like some kind of black magic, i assure you it isn't. The math required to accomplish this is simple.

The sounds of bullet impacts, supersonic shock waves and muzzle reports needs to be thoroughly addressed because it is here, during the opening minutes of this event, that a significant mistake was made by many witnesses and this mistake has led several researchers to suggest or conclude that there were indeed multiple shooters.

The problem here is that there were several very different gun related sounds that night and the dramatic difference between them has been incorrectly interpreted by some as sounds which originated from different weapons in different locations when in fact all of the sounds can be traced to the same origin. One of the sounds was generated by bullets impacting the asphalt, glass, metal and other objects at the venue. Another sound was produced by the supersonic boom produced by a projectile traveling faster than the speed of sound. The third sound was produced by the muzzle reports (the 'bang') of the weapon firing those bullets. In the witness video recordings the sounds of the supersonic boom typically have a higher frequency and amplitude and a shorter duration than the sound of the muzzle report. In other words they are generally louder and sharper, sounding more like a 'crack' than a 'bang', while the muzzle reports sounded more like a 'bang' and were not generally as loud at the concert area. I am quite certain that those witnesses who stated that the gunfire did not sound authentic, such as those who attributed it to firecrackers for example, said so because they queued in more on the louder cracks of the supersonic booms which sounded much more like firecrackers, rather than on the muzzle reports which followed shortly thereafter. This is an innocent mistake, one which i initially made myself even though i am familiar with guns, however i cannot overemphasize the significance of this mistake because it alone has sent otherwise creditable people off on wild goose chases for a second gunman which the acoustic evidence does not reveal.

Another interesting aspect that was likely in play during this event is something called 'normalcy bias' which is basically where the mind attempts to put a radically abnormal event, like being shot at, into a normalized context. This phenomena may explain the behavior of one apparently drunk guy who stood up among a sea of people attempting to protect themselves in order to offer a one-fingered salute to the shooter while bullets were raining down in his immediate vicinity. I noticed many other people behaving in a similar way where they were casually walking around, failing to take cover, failing to determine where the shots were coming from, attributing the gunshots to firecrackers, etc..

The Stephanie interview

Watching and listening to the witness videos without having a background in gunfire can easily mislead one to conclude that there were multiple shooters and i'm quite certain that many of those present at the concert drew this erroneous conclusion in real-time, some even stating that they felt as though they were being chased, such as Stephanie does in this interview with Fox 5:

Video title: Vegas-Paddock shooting - Fox 5 interview and commentary regarding witness Stephanie 1-Oct-2017

When you extract the audio portions of the witness videos from the venue and look at the waveforms with audio editing software however -- and i very much need to stress look, rather than just listen -- it is readily apparent that while there are indeed different and very distinct sounds related to gunfire, it is quite obvious that they are married to each other in repeating patterns.

I'm certain Stephanie wasn't being deceptive when she stated that it felt as though she were being chased, nor when she said she could not understand how all of the gunfire could have come from one shooter, however we can understand how the trauma of an event of this magnitude could easily result in an inaccurate interpretation of the event, especially when it is being recalled shortly after its conclusion and before she has had a chance to fully process what happened. An example of this is when Stephanie states that she felt like she had been running for approximately 30 minutes while the gunfire continued, though we know it lasted lasted only about 10 minutes. Like many other witnesses and researchers, Stephanie is probably not intimately familiar with gunfire and has probably never experienced a mass-shooting before.

How evidence was processed

My research into the acoustic aspect of the Vegas shooting went something like this:

  1. Procure multiple witness videos for analysis where the witnesses were in close proximity to the music concert at the Route 91 Harvest Festival
  2. Plot the witness locations on a map using visual references from their videos
  3. Extract the audio tracks from the witness videos to be used for waveform analysis
  4. Note the times of the gunfire bursts and bullet impacts or supersonic booms in each audio file for each witness recording
  5. Analyze each burst of gunfire in each audio file in order to find samples that would provide good data with regard to calculating bullet impact/supersonic boom to muzzle report delay times
  6. Determine the time offset between bullet impacts/supersonic booms and the following muzzle reports for each sample where the quality of the sample permitted
  7. Using some simple math and the bullet impact/supersonic boom to muzzle report time difference, plot a circle around each witness that indicates the approximate distance of the shooter from that witness
  8. Gather enough data from enough witnesses to be able to indicate the position or positions of the shooter or shooters which can be determined from where the circles around multiple witnesses converge

'Looking' at the sounds

Bullet Impact Followed By Muzzle Report Waveform
Example waveform showing bullet impacts or supersonic booms and following muzzle reports from the Las Vegas mass-shooting, 1-Oct-2017

The audio waveform above represents a very typical rapid fire sequence such as Stephanie experienced. Very similar sequences are found in nearly all of the multimedia files which i have examined from witnesses located at or near the festival venue, though to widely varying degrees of quality depending on the amount of background noise. This particular sample is from the 00:06:04-00:06:07 time frame of an audio track extracted from a video titled, RAW VIDEO: Escape from Las Vegas shooting.

In the graphic we can readily identify two distinct sounds, one of a higher amplitude which represents the supersonic booms or bullet impacts of the projectile, and the other a lower amplitude which soon follows and represents the muzzle reports from the gun itself which is the only sound typically heard when a gun is fired, unless you're unfortunate enough to be on the receiving end. You will notice that the last three supersonic booms/bullet impacts marked on the graphic are closely followed by the last three muzzle reports from the gun. The delay between the two sounds depends upon the velocity of the projectiles, the speed of sound and the distance between the shooter and the recording device. Once you recognize the difference in the appearance of the sounds, you should be able to identify nearly all of the lower and higher amplitude spikes besides those which i have marked.

This pattern is found in nearly every one of the rapid fire bursts recorded by the witnesses. The only exceptions that come to mind are samples which were recorded far enough away from the venue that either the bullet impacts, the supersonic booms, or the muzzle reports were not recorded, or instances where the background noise overrode these sounds.

It is vital to understand that for every video that i have analyzed which recorded rapid fire bursts where the projectiles impacted at or near the venue, they all recorded both sounds in a distinct pattern, the first being the supersonic booms or bullet impacts (striking metal, asphalt, or glass in some cases), followed approximately 30 to 40 milliseconds later by the sound of the muzzle reports.

The reason the bullet impacts and supersonic booms are heard before the muzzle report of the gun by the concert goers is because the bullet (assuming a .223 cal. Remington 55 gr. cartridge) is traveling roughly three times the speed of sound (approximately 3239 feet per second muzzle velocity) while the sound of the muzzle report (the gunshot) is traveling much slower at approximately 1138.52 feet per second (80 F air temperature assumed) and therefore the impact of the projectile or the supersonic boom it produces is heard by the witnesses before the muzzle report when the witness is located closer to the target area than the weapon (the distance between the venue and the snipers nest has been estimated to be approximately 1,360 ft. or 453 yards). If these two, very distinct sounds were overlapping gunfire as some have claimed, then the following conditions would have to be true:

  1. Both gunman would have had to be using a bump-stock or similar device because the unique rhythm of the rapid fire sequences produced by such a device can be clearly heard in all of the samples analyzed.
  2. Both of the gunmen would have to had fired in almost perfect concert for every burst-fire sequence with one of them -- and it would have to be the same one each time -- leading the other by approximately 30 to 40 milliseconds and they would had to have ceased firing in the same order with roughly the same 30 to 40 millisecond offset.

This is crucial because these conditions alone largely disprove the multiple shooter theory since it is all but impossible for two human beings to coordinate their fire to this degree. In order to further drive these points home, let's demonstrate a typical rapid fire sequence in text form where 'a' represents the sound of bullets impacts or supersonic booms from the projectiles at the venue and 'b' represents the sound of the muzzle reports:


Although this example is crude, it is indeed representative of the actual gunfire. You will notice two things here which hold true in the actual video recordings and the data presented later and they are, 1), the delay between the supersonic booms/bullet strikes (a) and the following muzzle reports (b) is consistent. 2) the delay between the gunshots is not at all consistent and this is because, unlike an automatic weapon, a bump-stock device relies heavily upon forces and pressures provided by the body in order to operate it. In other words, both sounds follow exactly the same cadence with the bullet impact/supersonic boom always being followed 30 to 40 milliseconds later by the muzzle report. This would be essentially impossible were the sounds generated by two guns fired by two human beings.

Again, in order to reach a logical conclusion as to whether there was more than one shooter, it is vital to look at the audio waveforms of the recordings using audio editing software rather than only listen to them. Once you 'see' the sound and realize that there are two distinct sounds with different amplitudes and tones, yet both follow the same rhythm with approximately the same time offset, it becomes obvious that they both originate from the same source.

The 'taxi video'

Regarding what i call the 'taxi video', of which my copy is titled Vegas Shooting Taxi Driver's Video ! Must Watch B4 Well You Know , The Take Down !, it seems this video in particular has attracted loads of attention from those who wish to promote a multiple shooter scenario and it is not at all difficult to understand why they conclude this when you listen to it:

Video title: Taxi video of Las Vegas mass shooting at Mandalay Bay

This video was recorded by a woman operating a taxi in very close proximity to the Mandalay Bay hotel main entrance near the same wing (north) and approximately 32 floors below where the sniper nest is alleged to have been. In it there are several rapid fire sequences, some of which are very loud and clear, however we can also hear gunfire which sounds significantly muted and farther away. Note though that the two sounds do not overlap. The driver even comments about this, stating that the gunfire sounds "like it's coming from farther away". Many people have concluded that these different sounds present clear evidence of a second shooter, but this conclusion is incorrect in my opinion. Having said that, i must admit that i too had initially assumed that multiple shooters were firing from different locations when i listened to this video, but i eventually realized that there is a less dramatic and more logical explanation.

What i believe explains the different sounding gunfire is that the shooter, presumably in the Mandalay Bay hotel room, moved away from the broken window in order to fire at another threat, perhaps someone approaching their position from inside the hotel such as when Jesus Campos or Stephen Schuck were shot at. We are told the gunman fired approximately 200 rounds through the front door of room 32-135 at hotel security officer Jesus Campos and, later, hotel engineer Stephen Schuck. If that is true, and it certainly appears it is, then the shooter would had to have moved well away from the broken window of the hotel room in order to fire through the hotel room entry door at Campos and Schuck and this obviously would have resulted in a dramatic difference in the way the gunfire sounded to anyone outside the hotel. We also know the gunman fired multiple rounds at an airport fuel tank and those rounds presumably were fired from the broken window in room 32-134.

While the difference in the sound of the firing sequences as heard in the taxi driver video could possibly be explained by the use of different weapons and/or the shooter moving between the two broken windows in rooms 32-134 and 32-135, i think the most logical conclusion is that it was simply the result of the gunman shooting first from the broken window in 32-135, where all of the .223 casings were found, and then repositioning in order to shoot through the hotel room door at the approaching staff. Either way, i hope i have sufficiently explained how noticeably different sounds of gunfire could easily have originated from the same general location, and even the same weapon.

The result

According to the data i have derived from multiple witness videos, the hypothesis that i believe to be correct at this time is that there was only one shooter that targeted the venue at the Route 91 Harvest Festival in Las Vegas on the night of October 1st, 2017, and that shooter was located in or near the MGM owned Mandalay Bay Resort and Casino.

The locations of several witnesses who were positioned close to the festival are plotted on the map below. Surrounding and centered around each witness is a colored circle specific to that witness which, based on the data below, indicates the approximate distance of the shooter from that particular witness. The diameter of each circle was determined by calculating the projectile supersonic boom, or bullet impact, to muzzle report delay times as per the 'bullet time to distance' chart below.

If we look only at the data for a single witness, then the shooter could be positioned anywhere along the circumference of the circle surrounding that witness, however when the data for multiple witnesses in different locations is plotted, we can then determine not only an approximate distance of the shooter or shooters, but also their approximate position, or multiple positions if there was more than one. Looking at the image below, all of the circles around the witnesses converge closest to the Mandalay Bay which is consistent with a single shooter positioned in or near the hotel. The smaller red circle nearest the Mandalay Bay indicates where the circles tend to converge the tightest and thus indicates the approximate position of the gunman.

Las Vegas shooting, 1-Oct-2017, witness positions
Las Vegas shooting, 1-Oct-2017, where the small red circle indicates the most likely position of the gunman based upon the data derived from each witness video

The gap between where the circles converge and the Mandalay Bay could be because the bullet weight that i chose (55 gr.) is not accurate or perhaps the amount of gunpowder used in the cartridges was not accurate. Either of these variables would affect the diameter of the circles around the witnesses equally and thus put the shooter somewhat closer or further from the Mandalay bay, but still along the same line between the venue and the hotel. There are also other variables to consider, such as the precise location of the witnesses which i was not able to determine, though i believe the margin of error should be no more than a few yards and much less than that in some cases where there were clear visual references in their videos that could be accurately correlated with a location on a map. There may also be other variables which i have not considered, though i think it is unlikely that any i might have missed would significantly affect the general conclusion.

Regardless of the potential inaccuracies in my data as far locating the shooter, we still have the 'taxi video' and other audio/video evidence which clearly indicates that the gunman was in very close proximity to her position near the main entrance of the Mandalay Bay. Again, it is not only the raw data that indicates a single gunman, but also the sound of the gunfire which, except for the expected variations in amplitude, are very similar across the spectrum of witness videos i have analyzed in terms of the average firing rate, the subtle variations in the firing rate which is indicative of a bump-stock device, the burst times and the tone.

Personal observations

Following are a few of my personal observations that i think are relevant to this case.


I think it must be seriously considered that there are several instances of potential foreknowledge of this event, one of which arrived in the form of several posts on the public message board 4chan on September 10, 2017, roughly three weeks prior to the attack, by someone identifying them self as "john":

The Las Vegas mass-shooting and the "john" posts on 4chan
Three posts by "john" on the 4chan message board dated 10-Sep-2017 which indicate foreknowledge of the 1-Oct-2017 mass-shooting in Las Vegas

Another potential instance of foreknowledge resulted from statements made to the news media by an alleged eyewitness, Brianna Hendricks, who stated that a Hispanic-looking woman, accompanied by a male subject, pushed her way to the front row of the concert and told people that they were 'all going to die' approximately 45 minutes prior to the time the shooting began. Brianna stated the following:

It seemed she was telling us to either warn us, or she was part of it and she was telling us because she knew we were going to die. It was so scary.


It felt like she had knowledge of what was about to happen.


She said they're all around us and we were going to die.

According to Snopes -- a highly dubious resource if ever there was one -- they interviewed Brianna and claim that she altered her story in that the remarks of the unidentified woman may have been directed solely at a single person or small group which this woman had a dispute with. If this is true, could such alterations be the result of pressure upon her to conform to a predetermined narrative, or did Brianna feel that her original statement was inaccurate and wanted to correct it? Or perhaps she just described the event in a different way. I don't know the answer, but i think the bigger question is why the LVMPD failed to comment regarding the testimony offered by Brianna Hendricks and the unidentified woman who allegedly made the statements she spoke of. For more on the issue, watch Flaw in the Matrix - Las Vegas Shooting which includes an interview with Shawn Hendricks, Brianna's mother.

It is also quite interesting that James Murren, the CEO of MGM Resorts International which owns the Mandalay Bay, dumped 259,760 shares of stock on the 7th of September, 2017, and another 34,390 shares on the 8th for a total value of $10,024,632 and he did so during a time when the value of the stock was apparently rising. What kind of confidence is instilled among the investors when the CEO dumps the vast majority of their holdings in the company? The day after the shooting MGM Resorts International stock fell 5.7%. From Disobedient Media:

It’s currently unclear why Murren chose to sell when he did. To date, MGM’s stock has not experienced a significant decline in value due to the repurchasing program. It could be interpreted to run against the company’s interests for the CEO to convey a sense of urgency in the selling of his shares by disposing of them immediately after the commencement of his company’s share repurchase program. It’s also strange that the CEO of a company would sell more than half of their stake (let alone 80%) in the company that they represented.

Further details regarding these stock transactions can be found at The Ledger Gazette.

James Murren was not the only one who profited huge as a result of the falling value of the stock. On August 14, 2017, George Soros placed a put call for 1,350,000 shares on MGM Resorts International for a profit of $42,242,000, the details of which are covered in the following video, Follow the Money / George Soros - Las Vegas Shooting, by Jake Morphonios. According to his YouTube page, "Jake Morphonios is the chief investigator for the Blackstone Intelligence Network. His background is in financial crimes investigation, journalism and Middle Eastern geopolitics. Jake has worked as a strategist and adviser to several political campaigns, including those of presidential candidates Steve Forbes and Ron Paul.".

For details regarding some of the other profiteers of the MGM stock price fall, see the article Insider Trading and Financial Anomalies Surrounding the Las Vegas Attack. The LVMPD and the FTC have yet to comment on these trades as far as i am aware.

The whirlybird sniper

Regarding the completely baseless speculation that there was a sniper shooting from a helicopter, good luck proving that a), it happened, and b), that a legally required anti-collision beacon or strobe light, which happens to be flashing terribly out of sync with the gunfire, is actually muzzle flashes. As per the FAA Night Operations Handbook for aircraft, chapter 13, pg. 13-7, 13-8:

All recently manufactured aircraft certificated for night flight must have an anticollision light that makes the aircraft more visible to other pilots. This light is either a red or white flashing light and may be in the form of a rotating beacon or a strobe. While anticollision lights are required for night visual flight rules (VFR) flights, they may be turned off any time they create a distraction for the pilot.

Understand that i am not stating as 100% certifiable fact that only one shooter targeted the concert, but i will confidently state that the data which i have accumulated over the better part of a week, including what my eyes see and ears hear, does not indicate the presence of a second shooter, not at, nor near the venue and certainly not from a helicopter. Again, for the purpose of this work, i have not seriously considered shooting events which may have occurred at other locations, though every one of these reports was apparently addressed by police and found to be without merit.

The drugs

In my opinion, Paddock does not seem to fit the profile of a mass-murderer given what information is available at this time, however if he was in fact prescribed diazepam (Valium) as indeed appears to be the case, then the potential side-effects of this dangerous and mind altering drug must be considered as a possible factor for his behavior. It is also well worth mentioning that such drugs are present in many mass shootings dating at least as far back as Columbine (20-Apr-1999) where Kevin Harris was apparently taking fluvoxamine (Luvox) and Dylan Klebold is alleged to have been taking Paxil and Zoloft. One could argue that it sounds quite reasonable that such drugs readily appear in these mass-shooting events because the people taking them were diagnosed and treated for psychological problems, however at least some of the previous mass-shooters showed no tendency toward violence whatsoever prior to the consumption of these drugs and in fact some have written or verbalized how the drugs made them feel angry, depressed and/or disconnected soon after they began taking them. The potential side-effects for diazepam, as well as many of the mind-altering SSRI drugs, are quite alarming and include the following:

  • aggressiveness
  • agitation
  • anxiety
  • confusion
  • delusions
  • depression
  • discouragement
  • false beliefs that cannot be changed by facts
  • feeling sad or empty
  • feeling that others are watching you or controlling your behavior
  • feeling, seeing, or hearing things that are not there
  • hyper-excitability
  • insomnia
  • irritability
  • lack of memory of what takes place after a certain event
  • loss of interest or pleasure (reported by Marilou Danley to investigators)
  • nightmares
  • outbursts of anger
  • psychoses
  • rage
  • restlessness
  • seizures
  • sleep disturbances
  • stimulation
  • unusual behavior (reported by Marilou Danley to investigators as well as by Paddock's doctor)
  • unusual tiredness or weakness (reported by Stephan Paddock to primary doctor, family, friends)
  • change in consciousness
  • loss of strength or energy (reported by Stephan Paddock to primary doctor, family, friends)
  • muscle pain or weakness (reported by Stephan Paddock to primary doctor, family, friends)
  • unusual drowsiness, dullness, tiredness, weakness, or feeling of sluggishness (reported to primary doctor by Stephan Paddock)
  • decreased interest in sexual intercourse (reported by Marilou Danley to investigators)

From an article on titled Valium Overdose Symptoms, Signs, Effects & Treatment, we find a list of symptoms for someone who consumes too much Valium and they include the following:

  • agitation
  • anxiety
  • panic
  • lowered mental capacities
  • hallucinations
  • confusion

Also "inappropriate behavior and other adverse behavioral effects have been reported when using benzodiazepines" according to the drug sheet on the FDA website.

We can turn to page 23 of the LVMPD Preliminary Investigative Report in order to confirm that Paddock seems to have been suffering from several problems which could be attributed to diazepam:

Marilou Danley stated Paddock’s demeanor changed over the course of the last year. According to her, Paddock had become "distant" and their relationship was no longer intimate.

And from page 24:

Paddock made numerous claims to friends and family that he consistently felt ill, in pain or fatigued.


The physician described Paddock as "odd" in behavior with "little emotion" shown. He believed Paddock may have had bipolar disorder however, Paddock did not want to discuss that topic further with him. Paddock also refused anti-depressant medication but accepted prescriptions for anxiety.

If Paddock refused anti-depressant medication, that would seem to indicate that his doctor had diagnosed him with depression. What role might this have played in the shooting, even without the side-effects associated with diazepam? What can happen when someone suffering from depression is prescribed diazepam which is intended to treat anxiety?

And finally from page 38:

The attached southeast bathroom had a tub along the north wall with two glass vacuum suction holders on top of the tub ledge, a sink counter along the south wall with toiletries to include a prescription for "Diazepam 10 MG" in the name of "Steve Paddock", and two inhalers.

The obvious questions here are, when was diazepam first prescribed and how much was being consumed by Paddock, because the symptoms reported by Paddock's doctor, his girlfriend and himself, are all in the list of side-effects for diazepam. According to, the maximum recommended dosage of diazepam for treating anxiety in an adult is 10 mg. four times per day and according to the police report, Paddock's prescription was for 10 mg.. Furthermore, under the section titled 'What should I avoid while taking diazepam?' on, it clearly states that alcohol should be avoided:

This medication may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Avoid drinking alcohol. Dangerous side effects could occur.

Grapefruit and grapefruit juice may interact with diazepam and lead to unwanted side effects. Discuss the use of grapefruit products with your doctor.

And yet on page 10 of the LVMPD Preliminary Investigative Report we read the following regarding the sequence of events for September 30:

From approximately 1204 to 1215 hours hotel staff serviced the private mini bar of room 32-134.

Was Paddock consuming alcohol along with diazepam and, if so, how much? How much diazepam was he taking? Was he taking more than what was prescribed? Are the side-effects of diazepam and alcohol the motive that law enforcement is seeking? We know from an autopsy conducted by Dr. Lisa Gavin of the Clark County coroner's office that nordiazepam, oxazepan and temazepan where found in Paddock's urine which apparently indicates the presence of diazepam. Though there is no mention of alcohol, this does not necessarily indicate that Paddock was not drinking.

In a UPI article regarding the autopsy titled Autopsy for Vegas shooter Stephen Paddock shows no insight into motives, we read:

A separate examination of his brain at Stanford University found no major abnormalities, including no evidence of Alzheimer's disease.

This statement seems to contradicts the very next sentence in the same article which says that "The brain had 'the most striking abnormality' in the hippocampus, a part of the brain involving human learning and memory." An article in the Los Angeles Times adds a bit more detail:

The autopsy also included a short report from Stanford University, which studied his brain to determine whether there was anything unusual. It revealed what it called "the most striking abnormality" in the hippocampus, a part of the brain involving human learning and memory. The report did not say whether the abnormalities might have affected his behavior.

At this point in time it is my opinion that the drug diazepam may have played a role in this shooting, however based on my research regarding the thoroughly corrupt, criminal and multi-billion dollar pharmaceutical industry, i can state to a high degree of certainty that if prescription drugs did in fact play a part in this shooting, this will never be revealed to the public, especially given that they are the largest donors to political parties and the mainstream media depends heavily upon them for advertising dollars.

From an article on the Waking Times website, Prozac Mass Murders: The Truth Comes to Light: "The Louisville Courier Journal reports that thirty years after Joseph Wesbecker went on a deadly shooting rampage in Louisville Kentucky, on September 14, 1989, the families and survivors of his actions have finally come forward to tell the truth. They were plaintiffs in a lawsuit against Eli Lilly because they had reason to believe that Prozac, manufactured by Lilly, had been the trigger that propelled Wesbecker on his violent rampage. Eli Lilly had paid these plaintiffs $20 million in hush money to conceal damaging evidence about Lilly’s culpability in marketing defective, deadly drugs from the jury in the Wesbecker- Eli Lilly trial."

The venue lights

Why were the venue lights switched on soon after the shooting started, thus illuminating the crowd and making them easier to target? Who made this decision?

The guns

Why all the guns? Even if we assume Paddock was selling guns, which appears to be likely according to the LVMPD, why cart a truck-load of guns to a well planned mass-shooting when you only need a few and you know that it's highly unlikely you're going to escape afterward? A handful of guns would have been sufficient, perhaps three to five for sniping and spraying which would allow for barrel overheating and varying distances, along with one or two for close range encounters with security and law enforcement. Finally, a handgun to end it all when your options run out because it's quite obvious that the suspect had little hope of escaping from the 32nd floor of a hotel in one of the most surveilled cities on the planet. So why all the guns? Does diazepam, possibly in combination with alcohol, provide an answer to the seemingly nonsensical decision to bring approximately 21 suitcases containing weapons and ammunition?

According to information contained in the final FIT police report, Paddock fired 14 of his guns, 11 of which were AR-15's, nearly all of them equipped with 100 round magazines:

Recovered in rooms 32-135 and 32-134 were 1057 shell casings. Forensic analysis was completed on all of the shell casings that were recovered. Of the rifles recovered from inside rooms 32-135 and 32-134, 14 were found to have been fired.

And there's more

Matt Agorist asks five questions with no apparent answers regarding the Vegas-Paddock shooting in an his article, 5 Unanswered Questions that Still Remain 2 Years After the Vegas Shooting. The questions are:

  1. Report suggests Paddock’s girlfriend worked for the FBI
  2. Officers seen on body camera footage cowering in fear as Paddock murdered people one floor above them
  3. Paddock Reportedly Warned His Brain was ‘Hacked’ and He Was Under Gov’t Control
  4. Information suggesting Paddock was an arms dealer completely ignored by MSM
  5. Vegas police seen on video being instructed to turn off their body cameras

The first and third statements are most interesting to me. Was Paddock 'Sirhan'd' by the FBI or some dark part of the intelligence community? As crazy as it may sound, there is indeed a great deal of evidence that a persons mind can be controlled in such a way as to produce a Manchurian Candidate. Furthermore, the FBI has clear track record of manufacturing and aiding terrorists as i will touch upon in a moment. While Paddock's psychological problems, diazepam and potential alcohol consumption may be responsible for his delusional behavior, this doesn't answer the question of Marilou Danley allegedly listing the FBI as an employer on a credit application.

From the article:

The escort was reported missing by her boyfriend just after the shooting and a former escort who once dated Paddock spoke out about the sheer insanity involved in this case.

“She was telling girls after work that she was scared something would happen to her,” claimed former escort Mikaela, whose full name was withheld to protect her identity according to Radar Online. “She was booked the day before or the day of the shooting before she disappeared.”

According to her testimony, Paddock claimed to be a government experiment.
“There’s messages where Stephen is telling her he’s a government experiment and that they are listening to everything he says and does, and they can hack into his brain and take over,” Mikaela said.

If you combine the possibilities of Paddock being mind controlled with the proven track record of the FBI in creating terrorists along with the "john" posts on the 4chan message board which cannot be ignored (they reveal location, names and motive), it makes one wonder. And if that's the world we live in, what's next and what can be done to stop it?


Though i have no proof, based on my previous research into such events, i suspect there is a great deal more to this story than a "lone nut" and diazepam. I think this shooting may have served multiple agendas, including a continued assault on our freedoms, the opportunity for certain powerful investors (George Soros and Michael Chertoff according the "john" posts on 4chan) to profit from the sales of security equipment, as well as many others who profited from the drop in MGM's stock value, and potentially to instill yet more fear in the public mind which can then be leveraged to influence public opinion. I am also extremely suspicious of the FBI and what role they may have played (and i emphasize may) in the planning of this event. This corrupt organization has an incredibly disturbing track record of blatant criminal activity in many previous instances, including the deliberate manufacturing of domestic terrorists in order to later arrest them, thus "preventing" a terrorist attack that otherwise would likely not have occurred and justifying their enormous budget in the process.

On a personal note

This has been a difficult undertaking for me. Because i choose to do a video and audio analysis of the gunshots, and because i needed to hear every detail in the witness videos, i had to wear high quality headphones and this made it seem as though i was physically with the people at the concert venue. The screams and pleas for help and all of the noise and confusion during this horror lived inside my head for several days as i listened over and over again to these videos. It's difficult and unsettling to imagine what it was like for those that actually lived it.

The data

If you're curious about how the data for the map above was derived, read on. I may work further on this, so do not consider it complete. There may be errors, so do not consider it perfect. If you have any feedback, questions, or find any errors, feel free to leave a comment or contact me privately.

Note also that i have combined both bullet impacts and supersonic booms under the 'impact' heading since whether the first sound to reach the witnesses is a bullet impact or a supersonic boom is irrelevant because both would have been heard by the witnesses at the nearly precisely same time.

General observations

general observations

* several shot sequences are approximately 10 seconds

* no shot sequences seem to be any longer than 10-11 seconds

* some 10 second shot sequences are very close to other firing sequences, such 
as the 00:03:25-00:03:27 and 00:03:30-00:03:40 sequences in the [001] video - if 
the shooter had to reload after a 10 second burst, i doubt there was enough time 
to eject, reload, reacquire the target area and begin firing, nor do i think 
there was time to pick up another weapon which, for the example given, there is 
only approximately 3 seconds between bursts

* i cannot detect any muzzle flashes from the Paddock hotel room (or anywhere 
else) from the videos i examined, particularly from witness [001] which includes 
some fairly steady footage of the Mandalay Bay during a rapid fire sequence - i 
adjusted the brightness, contrast and color saturation of the video to a large 
degree and could not observe flashes - although many of the videos are not of 
the highest quality, i still find this odd - the shooter certainly was not using 
a silencer and i tend to doubt that a flash suppressor alone would mask the 
muzzle flashes

* although Paddock apparently had 20+ guns in his room, it is unusual for any of 
the gunshot sequences to differ in amplitude and tone within the same witness 
recordings and often they differ little between different witness recordings - 
the bump-stock type repetitive fire variations are present in every video - this 
begs the question as to whether Paddock, the alleged shooter, ever used more 
than one type/caliber of weapon and, if he did not, then why bring 20+ guns 
which is an utterly absurd number

Ballistic calculation resources

Atmospheric conditions in Las Vegas, October 1st, 2017:

Las Vegas weather 1-Oct-2017
Las Vegas weather 1-Oct-2017

A 20 degree angle was used for ballistics calculations based on a rough estimate using Google Maps:

Mandalay Bay Shooter Angle (estimated)
Mandalay Bay shooter angle (estimated)

The cartridge used for ballistics calculations was a .223 Remington, metal case, 55 gr. cartridge. This caliber is based on the multiple AR-15 weapons found by police in room 32-135, most of which were equipped with bump-stock devices. The type and weight of the bullet is estimated. Here is the ballistics table for that cartridge:

.223 Remington Metal Case 55gr Ballistics Table

This is the chart i used to calculate bullet time to distance, corrected for atmospheric conditions and shooter angle:

How calculations were preformed


* ballistic calculations were preformed using the Ballistic Calculator tool from [4]
* distances from projectile impacts to muzzle reports are calculated from 
witness recordings close to the concert where projectile impacts are recorded 
before the audible muzzle report - from this data the estimated distance to the 
shooter is derived and, given enough data from multiple witnesses, shooter 
position can be derived
* cartridge (assumed): .223 Remington, Remington Metal Case, 55gr (used for 
ballistic calculations)
    - ballistic coefficient: 0.202
    - initial velocity: 3240 ft/s
    - bullet weight: 55 gr.
    - zero range: 100 yds.
    - shooting angle: 20 deg.
    - sight height: 1.5"
    - wind velocity: 0
    - wind angle: 0
    - drag function: G1 | Ingalls
    - air temp: 80 F
    - altitude: 2030 ft.
    - atmospheric pressure: 29.53
    - relative humidity: 24%
* Las Vegas temperature, 1-Oct-2017, 10p: 80 deg. F (used for ballistic 
calculations and speed of sound) [1]
* Las Vegas relative humidity, Oct: 24% (used for ballistic calculations) [3]
* speed of sound @ 80 deg. F: 1138.52 ft/s [2]
* map radius's surrounding each witness location as plotted on the map are 
calculated using the projectile impact to muzzle report delay figures - added to 
the distance is the difference between the witness location and the target area 
(rough center of open area in front of stage) to create the corrected distances 
which are then used to calculate the radius around the witness - the corrected 
distance was measured on Google Maps using the built-in measuring tool

* approx. distance to center of concert area: 85'

* the following distances were averaged to plot witness circles:
    1040 + 1025 / 2 = 1032.5'

* it is assumed that some of the firing sequences in this sound track consist of 
bullet impacts followed by muzzle reports for the following reasons: 1) the 
shear sharpness of the higher frequency sounds preceding the lower amplitude and 
lower frequency sounds, 2) the 00:00:14-00:00:16, 00:02:37-00:02:44 and 
00:02:44-00:02:47 samples where apparently bullets can be heard striking objects 
in the vicinity of the witness, possibly glass in the 00:00:14-00:00:16 sample 
and metal in the 00:02:37-00:02:44 and 00:02:44-00:02:47 samples, and 3), 
because of the witness location which is much closer to the concert than to 
Mandalay Bay which would account for bullet impacts being recorded before muzzle 
* at 00:02:43.27, 00:02:45.9 and 00:02:46.3 there are bullet impacts that sound 
like they are extremely close to the witness - one of the latter two impacts, 
and i don't know which, may possibly be seen in image file 
"003-bullet-impact.png" - this could just be an anomaly in the video since this 
small bright area on the pole in front of the witness appears for only a single 
frame, however it does correspond with the spike in the audio that sounds like a 
bullet striking a metallic object

Post analysis updates

25-Jul-2022: On or around 13-Jan-2022, Mindy Robinson, an activist and self-proclaimed investigative journalist, released a feature documentary, Route 91: Uncovering the Cover Up of The Vegas Mass Shooting, in which she attempts to make a case for multiple shooters in multiple locations that night, including multiple shooters targeting people at the concert venue.

While some of the evidence in the documentary is compelling, much of it is very weak or factually incorrect. Other evidence is largely devoid of credibility, such as shots being fired from helicopters and bullet trajectories that indicate some victims were shot by someone on the ground. To make the latter case, Robinson shows us what is apparently a forensic diagram of a head with the bullet path being parallel to the ground which of course proves absolutely nothing since the victim could have been looking up in the direction of Mandalay Bay when they were shot. In another instance Robinson tells us four victims were shot from a very high angle which, contrary to her insinuation of being shot from a helicopter, could simply mean that these victims were looking down or were bent over, perhaps taking cover or helping a victim, when they were shot. Robinson spends substantial time analyzing flight path data of aircraft operating in the vicinity of Mandalay Bay in order to support her untenable theory that shots were fired from possibly multiple helicopters.

Robinson also insinuates that it was not possible for Paddock to target people in the venue without a scoped rifle, of which there was only one Paddock's arsenal (i believe he used this one to target the airport fuel tanks). She seems to insinuate that Paddock was targeting individuals rather than the crowd in general which is absurd. Paddock (assuming he was actually the shooter) was not targeting individuals, he was targeting a large, densely packed crowd from approximately 450 yards away. There was no need to use a scope at that range on a crowd of that size in order to be assured of hitting people with what was essentially an automatic weapon.

Robinson further insinuates that it was not possible for Paddock to have used a bump-stock device since they are unreliable. She then shows us a single video which she uses as evidence to support her claim in which it appears the shooter had no previous experience with a bump-stock device. There is also no indication that the bump-stock device used for the demonstration was the same as that used by Paddock. Robinson seems to have cherry-picked this video and ignored videos such as How does a bump stock work? from ABC News which is the first one i found when searching for "bump-stock demonstration video". Finally, the fact that a bump-stock was used is positively clear when listening to the many witness videos and looking at audio waveforms.

In between all of this nonsense, half-truths and wild speculation, of which i've referenced only a small portion, Robinson does bring forth evidence about the discovery of empty bullet casings found on the ground in the venue area and elsewhere, however it's only the venue area that is of interest to me, and this presents a problem because, assuming those shells were fired during the time Paddock was firing and not just deposited there by someone for some unknown reason, it contradicts my own findings which conclude that there is no solid evidence of any gun fire originating in the venue area at any time according to any of the witness recording i analyzed (i should note that i analyzed many more videos than those referenced throughout this article).

The documentary features an audio analysis of waveforms which Robinson tells us was done by an unnamed sound editor with 20+ years experience and which proves that multiple gunmen were targeting the venue. The person doing the analysis is using a single audio track with no accompanying video captured from a single law enforcement officers body camera. The sound guy tells us that the officer never changed locations and only moved a few feet during the recording. He concludes to a high degree of certainty that overlapping gunfire can be heard in this recording. There are several problems with this conclusion:

  1. We have to assume the source and description of the video is accurate.
  2. Without video, we cannot be sure the officer (the recording device) didn't turn to face a different direction, or that they interfered with the recording such as by positioning his/her hand or arm in front of the microphone, or that someone else didn't move between the microphone and the sound source, any of which could have changed the audio sound and waveform drastically. The person doing the analysis does provide an important detail when he states that the officer moved a few feet during the two firing sequences and this alone could have affected what is heard in the audio and seen in the waveforms. In the second firing sequence he alludes to overlapping gunfire ("you can hear the guns in the background; you can hear the primary in the background") however the audio sample of the second firing sequence is poor. While this could be evidence of a second shooter, it could also be that something changed with how the sound was being recorded due to the officer moving, others moving, the gunman changing his aim, etc.. Lastly, only one audio analysis was performed whereas i analyzed many media recordings using timings, math and ballistics and i have no doubt that my methods present far stronger evidence.
  3. As an alleged audio editor, possibly with no ballistics experience, this person does not seem to have considered bullet shock waves or timings in his analysis.

I immediately contacted Robinson after watching her documentary (i saw it right after it was released, i'm just late writing about it) with the intention of working together to figure out how our investigations could lead to opposite conclusions, however she soon became confrontational and refused to even consider the evidence brought forth here, thus any collaboration with her was impossible. She claims to be an investigative journalist, but i have to wonder what kind of investigative journalist refuses to consider evidence, much less forensic evidence, that challenges their current beliefs.

  • due to a reader comment, i realized that i may have been interpreting the supersonic sound waves of bullets as bullet impacts, thus i have corrected this in the article, however this error should not make any difference in my calculations since both the supersonic shock wave and bullet impact sounds would have reached the witnesses at the same time almost exactly - this is because the supersonic sound of a projectile emanates from the projectile and not the gun, thus the generation of the supersonic crack would have ended at the same time the bullet impacted an object

  1. Hello,

    Just came across your work for the 1st time. Wow, quite the investment in time. You clearly have an analytical mind and are detail oriented. I’ve been doing my own analysis since the shooting. You’ve made some very keen arguments. However the math and several observations are way off. For example, the time delta between the muzzle blast and sonic shock wave is NOT the same for every bullet. It varies according to the “miss distance” proportional to the distance to the shooter and a trig function of the miss distance/angle. For example at the oasis apartments, this delta is small (< 100ms), relatively speaking and and should not be if the "lag" was simply a function of distance. The same bullet, but recorded near the center of the concert would have a much larger "lag" on the order of fractions of a second.

    If you wish to talk a little, i'm up for it, I can spare a few minutes a day.

    Also, determining if the shots came from the same shooting location is much much easier. Simply align them all (if you can) like the NYT artical did for their reporting. If each recording for each stationary location has all the volleys and sounds lining up exactly with all the other recordings then they come from the same source location or it's complementary pair. It's a fasinating experiment and quickly reveals which shots came from the same source location. Of course it takes considerable time to perform this experiment.

    This is the first article I've read that went into as much detail behind the conclusions.

    1. hi Richard – thanks for your comment

      i’d like to keep as much of our discussion as feasible in public view for the benefit of others, however if you need to contact me privately, you’ll find contact a link at the bottom of every page

      first of all, what you are calling the sonic shock wave, i am calling the sound of bullet impacts and this could be a significant (and embarrassing) error on my part, though off the top of my head i don’t think this would affect any of my data

      though i am familiar with gunfire, i don’t recall being on the down-range side of a hyper-sonic projectile and though i know about the sonic-boom phenomenon, apparently i overlooked this, partly due to the sounds of actual bullet impacts hitting glass and metal in some of the recordings – so i may have some correcting to do in that regard

      regarding the Oasis apartments, how does this figure into the equation? i’m not aware of any shots fired at, or in close proximity to that location

      with regard to my math being inaccurate, how so? i understand the method you suggest is different than mine, but different methods don’t necessarily equate to different results in so far as shooter distance and location

      looking forward to your reply – it’s nice to chat with those who do serious research

  2. Hi again,

    Would be happy to discuss things in public. I’m not sure what formatting syntax this blog supports, so I’ll
    draft some stuff offline then post links here when done. In the mean time have a gander at:

    and particularly the page numbered 749

    I’ve just recently started this repository so take everything but the Library with a grain of salt.

    1. thanks Richard – i’ll be looking at what you have, and i think creating a repo was a great idea! if you want to dump any of my stuff in it, feel free, or let me know if you want me to submit something

      as for what format you can post here, some basic HTML (p, blockquote, a, ul, ol, li, code) is supported and, i believe, some markdown – regardless, i can always reformat what you post if it gets junked

    2. i read the ‘summary of gunshot acoustics’ doc and i don’t think it tells me a whole lot i didn’t already know (then again, i suck at math), but it does reinforce a suspicion i had regarding why the circles i drew around the locations of the witness recordings fall short of the Bay, which may well be due to the bullet velocity decreasing – this seems to make perfect sense because, if that were a constant, the delta between muzzle blast and sonic wave would have been greater and thus the circles would have been larger and, i’d bet, would have converged right on the N. wing of the Bay

      as far as the different sounds and propagation’s described in the doc, i believe it means practically nothing to my data for a couple reasons, one being because i analyzed the same kinds of sounds in the recordings, which is to say that the sounds i used were very distinct – if there was any doubt, i didn’t include it in the data except to note that it occurred – this why i was only able to use a relatively small number of shots to produce a result

      so as far as i can see, my data, while flawed in the sense that the math may be crude, still yields a solid result

      now i’m off to read the next one…

    3. regarding the 2nd doc, same thing – both of these documents talk a lot about the sonic wave and indicate how different the timing can be between the wave and the mic depending on where the gun and the mic are placed relative to each other

      in the first doc they’re testing at only a few meters and firing ~45 deg. off of the mic – the situation in Vegas was very different where the gun was hundreds of yards and the target ‘cone’, if you will, was quite small from the shooters perspective, but the sonic cone was quite large from the target perspective which, if i’m understanding this somewhat correctly, tells me that, again, my calcs should be reasonably accurate, even if crude, and i think that’s reinforced in the final image in which the circles converge nearest the N. wing of the bay

      that said, the equations in both docs may as well be ancient Sumerian text – i understand none of it

      1. Thank you for your timely response and taking the time to read the docs.

        Without a little math I’m kinda lost, so guess we are on opposite sides of the coin.

        I’m going to mull this over a little bit and come up with a non-math approach to explain some things

        Thanks again for taking the time to share your work.

  3. “Foreknowledge”…
    Shawn Hendricks, mother of Briana Hendricks, on her interview, in (Flaw in the Matrix – Las Vegas Shooting) Brian Shields channel)- Used the same word, “Surrounded”, describing what SHE heard from the very guy, who was being harassed by the two Hispanics !! Then at 5:12 on Brian’s Vid. The Officer said–”She was heavy set” -”I actually escorted her out”

    “The Drugs”…
    I’m beginning to believe Paddock just may be, the other person, the one shooting from 135. That would explain the absolutely, pathetic amount of damage done,considering the arsenal available to him in that room. (There’s really no good way of saying what I just said !!)

    And for sure, in volley 6, as seen in Fourtraxer’s Vid. “Bullets Hitting Ground”. he used up a 100 round clip, right down an empty alley !!! ALL,- The bursts, volleys, and timing, from that night seemed absolutely CRAZY. ( seems like the diazepam/alcohol, may have done a number on him) “Thank God”
