Police found a 6-page manifesto on Matthew Livelsberger’s phone and say he used ChatGPT to plan his New Year's Day bombing at the front of the Trump International Hotel in Las Vegas, the LVMPD said at a news conference Tuesday.

LAS VEGAS (AP) — The highly decorated 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. The updates Tuesday come nearly a week after 37-year-old Matthew Livelsberger fatally shot himself just before the truck blew up.

The explosion was caused by fireworks and explosives in the bed of the rental Cybertruck, which had no faults, according to data.
