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.

Sheriff of the Las Vegas Metropolitan Police Department called the use of generative AI a “game-changer” and “a concerning moment” and said the department was sharing information with other law enforcement agencies.
