Almost a week after the event, we are continuing to learn more about the Cybertruck explosion in front of the Trump International Hotel in Las Vegas and the man behind it.

Las Vegas Metro police and federal partners held a press conference on the latest information they have on the investigation.

LVMPD Sheriff Kevin McMahill said they have recovered a six-page document on Livelsberger's phone that he describes as a "manifesto."
This is in addition to two letters that investigators recovered last week from Livelsberger's phone. The FBI has now confirmed that a letter sent to the Shawn Ryan Show podcast was written by Livelsberger.

McMahill said LVMPD is still reviewing the manifesto with federal partners and noted that some of the material may be classified, so they will not release the full document yet — only excerpts.

Within the documents, McMahill said Livelsberger believed he was being followed by the government all the way from Colorado.

"I want to make it clear that our suspect in this case has never had a criminal history nor was he on the radar of the FBI or the LVMPD prior to this bombing," McMahill said.

He used AI to plan his attack

There is clear evidence in the investigation that Livelsberger used ChatGPT artificial intelligence to plan his attack. Assistant Sheriff Dori Kohen showed prompts Livelsberger asked the AI in regards to gun purchases and how they can be used to ignite an explosion.

Video evidence of Livelsberger staging his attack

Police showed video of Livelsberger pouring racing fuel in the back of his Cybertruck, where investigators said there was more than 60 pounds of explosive material.

The video shows the fuel leaking from the truck, all the way from the parking lot where he poured it to the Trump Hotel valet.

Asst. Sheriff Kohen said Livelsberger's hands were on the steering wheel when he entered the valet area as further evidence to dispel rumors that the truck was in self-driving mode.
