Investigators also recovered video evidence of Livelsberger pouring fuel over the cybertruck prior to parking it outside the Trump hotel. In one video, a trail of liquid, that authorities say was racing fuel, can be seen leaking down the sides of the car as Livelsberger pulled up at the front of the hotel.

A laptop, cellphone and watch are still under review nearly a week after 37-year-old Matthew Livelsberger fatally shot himself just before the truck blew up.
