The driver of the Tesla Cybertruck that blew up outside Trump International Hotel Las Vegas on New Year’s Day has been identified as 37-year-old Matthew Alan Livelsberger, a U.S. Army service member from Colorado, U.S. officials said.

Livelsberger was shot in the head in what police believe was a self-inflicted gunshot prior to the detonation of the vehicle, police said.

Authorities used his tattoos, along with his credit cards, military identification and passport, to identify him at the scene.

“There are two tattoos, one of which was on the stomach and one of which is on the arm that we can see bits and pieces of it, as in comparison to what it is that we now know he had, on his body,” Sheriff Kevin McMahill of the Las Vegas Metropolitan Police Department said Thursday.

“That has given us a lot of confidence that this is, in fact, the same person, as well as of which the clearly obvious, which is the credit cards, the military identification, the passport,” he added.

Family:

Livelsberger appears to have at one point been married to Sara Livelsberger, a 38-year-old who lives in Delray Beach, Florida. The Denver Post reported that he had divorced in 2018 and remarried in 2022.

Fox News Digital has reached out to Sara Livelsberger for comment.

A Facebook page for Sara has been quiet since 2016, but makes multiple references to Livelsberger as her husband.

In Facebook posts from 2016, Sara said she was a registered Democrat and shared images that were disparaging of President-elect Trump. 

The Cybertruck was rented in Colorado, authorities said during a Wednesday news conference. 

The futuristic Tesla vehicle was complete with large firework mortars in the back and fuel canisters. It arrived in Las Vegas at about 7:30 a.m. local time Wednesday and drove up and down the strip before pulling into the Trump hotel. 

The vehicle was parked for about 20 seconds before it exploded, police said.

Authorities are continuing to investigate whether the incident was an act of terrorism, which came just hours after another U.S. veteran killed at least 15 people when he plowed a truck with an Islamic State flag down Bourbon Street in New Orleans.

Authorities are still working to determine a motive.

“It’s not lost on us that it’s in front of the Trump building, that it’s a Tesla vehicle, but we don’t have information at this point that definitively tells us or suggests it was because of this particular ideology,” said Spencer Evans, the Las Vegas FBI’s special agent in charge.
