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.

The men, Master Sgt. Matthew Livelsberger and Shamsud-Din Jabbar, who were both killed in the incidents, never served in the same unit, according to unit histories provided by the Army.

The man wrote a manifesto detailing issues with the current administration and used AI to plan the blast, police said.
