(UPDATE) LAS VEGAS, Nevada — The decorated US special forces soldier who blew up a Tesla Cybertruck outside the Trump International Hotel in Las Vegas shot himself in the head before the blast, authorities said Thursday, adding that his motivation was still "unknown."
Matthew Livelsberger, 37, a member of the elite Green Berets, took his own life in the rented vehicle filled with fuel containers and fireworks, which then erupted into flames, officials said.
