A driver who authorities say exploded a Tesla Cybertruck outside the Trump International Hotel in Las Vegas last week used artificial intelligence to plan the blast, according to the Las Vegas Metropolitan Police Department.

They also showed video evidence of him preparing for the explosion by pouring fuel onto the truck while stopped before driving to the hotel. He’d also kept a log of supposed surveillance, although the officials said he did not have a criminal record and was not being surveilled or investigated.

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.
