The New Year’s Day cybertruck explosion that killed one person outside a Las Vegas hotel was planned using ChatGPT, investigators say. Matthew Livelsberger, 37, of Colorado, carried out the attack, killing himself and injuring seven people on Wednesday, Jan. 1, LVMPD previously said.

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.
