WASHINGTON (Bernama-AA) – An active-duty US Army Green Beret who authorities say exploded a Tesla Cybertruck outside the Trump International Hotel in Las Vegas, Nevada last week used ChatGPT to plan the attack, Anadolu Agency (AA) quoted the Las Vegas Metropolitan Police Department as saying Tuesday.
Sheriff Kevin McMahill revealed during a press conference that the soldier, identified as Matthew Livelsberger, 37, of Colorado, utilised the generative artificial intelligence chatbot to gather information for his plot.
Assistant Sheriff Dori Koren said the suspect used ChatGPT to learn about the amount of explosives needed for the operation and where to purchase fireworks. He also researched the explosive potential of fireworks, their equivalence to other materials and whether firearm bullet velocity could ignite the explosives.
Asked whether it was concerning that Livelsberger used ChatGPT, McMahill responded, “We knew that AI was going to change the game at some point or another in, really, all of our lives.
“I think this is the first incident on US soil where ChatGPT was utilised to help an individual build a particular device, to learn information all across the country as they move forward.
“It’s a concerning moment for us but also instructive to share with law enforcement and other entities across the country,” he added.
Officials did not disclose the specific results that the ChatGPT tool provided related to explosives or firearms.
Authorities also uncovered a six-page document, described as a “manifesto,” during the digital forensic analysis of Livelsberger’s phone.
“There’s a variance of grievances and a constant evolution of his plans or intents of what he wanted to do. There’s mentions of political and social and cultural issues, to include criticism of the current administration,” Koren said about the alleged “manifesto.
“With this new information comes more questions than answers. I will not provide an opinion on what the documents mean, nor will we release information or documents that our joint investigators have not completely verified,” McMahill said.
Livelsberger, who was on leave from his base in Germany, fatally shot himself moments before the blast, which injured seven other people, according to authorities.
The FBI and ATF are assisting local investigators in examining the incident.
OpenAI, the developer of ChatGPT, has yet to comment on its use in planning the explosion.
