LAS VEGAS (AP) — The highly decorated Colorado soldier who exploded a Tesla Cybertruck outside the Trump hotel in Las Vegas used generative AI including ChatGPT to help plan the attack, Las Vegas police said Tuesday.
A laptop, cellphone and watch are still under review nearly a week after 37-year-old Matthew Livelsberger, of Colorado Springs, fatally shot himself just before the truck blew up.
A review of Livelsberger’s searches through ChatGPT indicate he was looking for information on explosive targets, the speed at which certain rounds of ammunition would travel and whether fireworks were legal in Arizona.
Livelsberger, an Army Green Beret who deployed twice to Afghanistan and lived in Colorado Springs, left notes saying the explosion was a stunt meant to be a “wake up call” for the nation's troubles, officials said last week.
He left cellphone notes saying he needed to “cleanse” his mind “of the brothers I’ve lost and relieve myself of the burden of the lives I took."
The explosion caused minor injuries to seven people but virtually no damage to the Trump International Hotel. Authorities said that Livelsberger acted alone.
Livelsberger’s letters touched on political grievances, societal problems and domestic and international issues, including the war in Ukraine. He wrote that the U.S. was “terminally ill and headed toward collapse.”
Investigators had been trying to determine if Livelsberger wanted to make a political point, given the Tesla and the hotel bearing the president-elect’s name.
Livelsberger harbored no ill will toward President-elect Donald Trump, law enforcement officials said. In one of the notes he left, he said the country needed to “rally around” him and Tesla CEO Elon Musk.
In a statement later Tuesday, a spokesperson for OpenAI, the developers of ChatGPT, said they were "saddened by this incident and committed to seeing AI tools used responsibly."
"Our models are designed to refuse harmful instructions and minimize harmful content. In this case, ChatGPT responded with information already publicly available on the internet and provided warnings against harmful or illegal activities. We're working with law enforcement to support their investigation."
