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.

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 outside the Trump International Hotel Las Vegas on New Year's Day is being investigated as a possible act of terrorism, sources said.

The suspicious blast is being investigated as a possible terrorist attack, three senior law enforcement members briefed on the matter told NBC News.

Local and federal officials are continuing to investigate the deadly explosion Wednesday morning of a Tesla Cybertruck outside the Trump International Hotel in Las Vegas, including whether it was motivated by terrorism or linked to a terror attack hours earlier in New Orleans that left 15 people dead.

Guests staying at the Trump International Hotel were forced to evacuate Wednesday morning after a Tesla Cybertruck exploded at the main entrance, killing one person and injuring seven others.

The Cybertruck fire and explosion is the second high-profile incident at the Trump International Hotel in Las Vegas in recent years.

Livelsberger used ChatGPT for instructions on how to calculate the amount of explosions needed for the blast and how he could buy a phone without providing his personal information, McMahill said.
