The person in the Cybertruck that exploded outside the Trump hotel in Las Vegas is believed to have been an elite soldier.

The man who rented a Tesla Cybertruck that exploded outside President-elect Donald Trump’s hotel in Las Vegas is an active-duty US special forces soldier, officials confirmed.

Las Vegas police identified Matthew Alan Livelsberger, 37, of Colorado, as the renter of the vehicle who drove the Cybertruck from Colorado to Las Vegas.

They said they were pretty sure it was the same person found dead in the vehicle after the explosion, but they were waiting for DNA testing to confirm it.

The body was burned beyond recognition and was found with a gunshot wound to the head that was believed to be self-inflicted, according to Las Vegas Sheriff Kevin McMahill.

The explosion injured seven people after the vehicle, filled with fuel canisters and fireworks mortars, exploded. Authorities said all injuries were minor.

Authorities said they had yet to determine any motive.

“I’m comfortable calling it a suicide with an attack that occurred immediately afterward,” Las Vegas Sheriff Kevin McMahill said during a news conference Thursday afternoon.

Livelsberger rented the Cybertruck on December 28 in Denver, Colorado. He has decades of experience with the US military, having served in the Army and National Guard.

He entered the active duty Army in December 2012, serving as a special operations soldier.

The US military said he was on approved leave at the time of his death.

Livelsberger’s father spoke to BBC news partner CBS and said his son was currently serving in Germany and on leave to visit Colorado and see his wife and eight-month-old daughter.

Livelsberger’s father said he last spoke to his son on Christmas and that everything seemed normal.
