The active-duty US Army Green Beret who authorities say exploded a Tesla Cybertruck outside the Trump International Hotel in Las Vegas this week struggled with injuries relating to his military service and said he was depressed while they were together a few years ago,

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.

Matthew Livelsberger, a highly decorated Special Forces soldier, is believed to have rented the Tesla truck, driving it to the entrance of the hotel and touching off an explosion. Livelsberger died of apparent self-inflicted gunshot wounds,
