Las Vegas Cybertruck explosion investigators piece together suspect's final hours

Matthew Livelsberger -- the suspected driver of the Tesla Cybertruck that exploded on New Year's Day outside the Trump International Las Vegas Hotel -- died from a self-inflicted gunshot wound prior to the blast, officials said at a Thursday press briefing.

Investigators had already collected significant evidence that Livelsberger was behind the wheel of the vehicle before publicly confirming their suspicions.

Officials found credit and identification cards in his name, purchase records identifying him as the owner of weapons found in the destroyed vehicle and identified tattoos similar to Livelsberger's on the driver's body, physical injuries to which slowed the identification process.
