2017 Las Vegas shooting conspiracy theories

There are some conspiracy theories about the 2017 Las Vegas shooting, the deadliest mass shooting by one gunman in American history. These hypotheses offer alternate explanations to the official version of the incident, including speculation about the involvement of shooters other than the identified perpetrator, Stephen Paddock.

One of the most popular conspiracy theories suggests the involvement of several shooters, which contradicts the official narrative that Stephen Paddock acted alone. This argument contends that additional gunmen were involved in the massacre, contesting the sole responsibility assigned to Paddock by law enforcement investigations. There is speculation that law enforcement, such as the FBI and Las Vegas Metropolitan Police Department are concealing information concerning the shooting, such as the motive or potential involvement of others. Conspiracy theories circulating online and in certain fringe groups contend that the federal government staged the 2017 Las Vegas shooting in order to justify the ban on bump stocks. The U.S Justice Department outlawed bump stocks in December 2018, but the Supreme Court reversed the decision in 2024 due to a lack of a legislative justification. Conspiracy theories say that Stephen Paddock utilized a machine gun, such as a M249 or M240, rather than the AR-15-style rifles discovered by law enforcement. Despite official investigations and evidence indicating the use of various firearms, including rifles, some individuals continue to believe in the machine gun theory. Accusations that the shooting did not occur or was orchestrated by "crisis actors" were among the theories. This interpretation is often fueled by a combination of disbelief in official narratives, the complexity and scale of the attack, and the quick spread of unconfirmed information online. Bruce Paddock, Stephen Paddock's brother, was arrested in October 2017 and charged with possessing over 600 photos of child pornography. This arrest came shortly after Stephen Paddock committed the bloodiest mass shooting in modern US history in Las Vegas. Bruce was reportedly bragging about his brother's acts, which prompted workers at his assisted living home in North Hollywood, California, to notify the authorities. No motive has been found for the Las Vegas shooting as of 2024.

Background
On October 1, 2017, Stephen Paddock opened fire from his 32nd-floor hotel room at the Mandalay Bay during the Route 91 Harvest music festival in Las Vegas, killing 60 and injuring hundreds more. Paddock was discovered dead in his room from a self-inflicted gunshot wound, and his motive is unknown.

Following the shooting, several conspiracy theories, misinformation, and fake news circulated on social media platforms such as YouTube and Facebook.  The Federal Bureau of Investigation has always stated that there was just one gunman in the 2017 Las Vegas mass shooting, dismissing suggestions of additional gunmen. The investigation found that Stephen Paddock acted alone, which is supported by considerable evidence, including witness testimony, ballistic analysis, and CCTV footage. Some individuals are skeptical and frustrated with the FBI's determination that Stephen Paddock did not utilize machine guns during the Las Vegas shooting. This is due in part to the high rate of fire heard during the attack, which many believed sounded like machine guns.

Political motivation
The conspiracy theory surrounding the 2017 Las Vegas shooting suggests that there was government involvement or cover-up due to inconsistencies in the official narrative and the quick closure of the investigation.

Antifa and left-wing connections
According to conspiracy theories, the gunman, Stephen Paddock, was linked with Antifa, an anti-fascist organization. Radio host and conspiracy theorist Alex Jones popularized this theory, claiming that Paddock selected a country music festival because it was likely to be attended by "pro-gun folks and Trump supporters." In 2017, Infowars stated that an unknown source said the FBI discovered Antifa literature in Stephen Paddock's hotel room, implying a link to Antifa. However, no evidence supports any link between Paddock and Antifa. Various contradicting explanations about Paddock's motivations arose as a result of a 4chan scheme to create fake narratives. These included assertions that Paddock had recently joined Islam, wrongly portraying him as a left-leaning Democrat who watched mainstream liberal media, and that he was a "Antifa Bernie Bro."

Islamic State involvement theory
Another assumption suggested that Paddock was associated with ISIS, which claimed responsibility for the massacre through its Amaq News Agency. Despite the group's history of claiming credit for various attacks, such as the Pulse nightclub shooting in 2016, regardless of actual involvement, this theory found support among certain conspiracy theorists. The FBI determined that Stephen Paddock, the perpetrator of the 2017 Las Vegas massacre, had no ties to ISIS or any other international terrorist organization. Similarly, the Las Vegas Metropolitan Police Department stated that their investigation found no ties between Paddock and any terrorist organization. They concentrated on determining Paddock's motivation and the circumstances surrounding the shooting. This early speculation caused confusion and misinformation in the public.

Brad Johnson, a retired CIA officer, and Rich Higgins, a former Pentagon official who served on the National Security Council during the Trump administration, argue that the Las Vegas shooting was orchestrated by a coalition of left-wing activists and Islamic extremists with political motives. They assert that Stephen Paddock’s actions were designed to undermine President Trump's leadership and create instability. According to their theory, the official narrative claiming Paddock acted alone is a deliberate diversion from a broader conspiracy. In a Politico report, Higgins, who served as the National Security Council's strategic planning director for a few months, stated that there is substantial evidence linking ISIS to the attack.

Foreknowledge
The bigger conspiracy theory is that the killing was coordinated or supported by members of the United States government or the "deep state." Proponents of this view, including Alex Jones, claim that the incident was a false flag operation aimed to push a certain political objective, such as gun control. Conspiracy theorists frequently use the bump stock ban in response to mass shootings, to back up their accusations. Some conspiracy theorists have referenced Las Vegas police's delayed response to Stephen Paddock's room during the 2017 shooting to back up their assertions. The leaking of crime scene photographs from Stephen Paddock's suite after the Las Vegas massacre has fueled conspiracy theories due to questions of lack of transparency. Concerns are raised regarding whether the leaked images properly show the crime scene as discovered by detectives. Speculations of tampering, such as relocating Paddock's body before documentation, call into question the murder scene's initial conditions.

Unusual stock market activity involving MGM Resorts International (which owns Mandalay Bay, where the shooter was positioned) was cited as evidence of foreknowledge. Conspiracy theorists cited a decline in MGM Resorts' stock price and unusual trade volumes prior to the attack as evidence of foreknowledge. This is similar to the 9/11 conspiracy theories in that both use unusual stock market activity as evidence of prior knowledge of a major event. Financial analysis and investigative reports frequently demonstrate that unusual trading behavior does not always imply knowledge of an impending incident. Such conduct is frequently explained by typical market behavior or unrelated financial strategy. These arguments stay hypothetical in the absence of hard proof connecting the trade activity to the shooting.

An anonymous 4chan member going by the name "John" posted a warning to "stay away" from Las Vegas on the sixteenth anniversary of 9/11, citing an imminent deadly attack. John, who merely sent cryptic messages, suggested staying away from big parties in Henderson and Las Vegas. He asserted that he knew in advance of a significant incident that was about to occur. Examining the messages' timestamps and substance frequently showed that many of them were posted after the shooting had already begun or were so ambiguous as to be unreliable warnings.

Multiple shooters theory
There is speculation that Stephen Paddock did not act alone, suggesting the involvement of multiple shooters. This theory posits that Paddock may have been framed as a fall guy by the actual perpetrators of the attack. It often references eyewitness testimonies and raises questions about how Paddock managed to transport numerous weapons into his hotel room. Several witnesses reported the initial chaos, saying they heard rapid and continuous gunshots, with some claiming there were "multiple shooters" actively involved. This eyewitness story, along with others like it, spurred controversy about the potential of other gunmen being involved in the tragedy. Many independent researchers and fact-checking organizations have disproven the multiple shooter theory. They cite forensic evidence, witness accounts, and investigative results that all support the conclusion of a single gunman. Assistant Sheriff Todd Fasulo and Sheriff Joe Lombardo both highlighted that Paddock acted alone, despite the intricacy of the attack and the amount of gear he was able to get into the hotel. Kymberley Suchomel, a shooting survivor, has publicly indicated that she believes there were multiple gunmen. She shared her story, saying that she remembered multiple shooters, one of whom was on the ground, along with other survivors she spoke with. She died a week later.
