Investigators know that a highly decorated Army soldier shot himself in the head inside a Tesla Cybertruck packed with fireworks just before it exploded outside Trump International Hotel in Las Vegas on New Year's Day,

The explosion caused minor injuries to seven people but virtually no damage to the hotel. Clark County Sheriff Kevin McMahill said Matthew Livelsberger, a Green Beret, likely planned a more damaging attack but the steel-sided vehicle absorbed much of the force from the crudely built explosive.

A Tesla Cybertruck exploded outside Trump International Hotel Las Vegas' entrance on Wednesday, killing the driver and wounding seven people, law enforcement officials said. The big picture: Clark County/Las Vegas Metropolitan Police Sheriff Kevin McMahill said at a Wednesday afternoon briefing that "camp fuel canisters and large firework mortars" were found in the back of the truck.
