(NewsNation) — The decorated Army soldier who drove a Tesla Cybertruck that exploded outside of a Las Vegas, Nevada hotel suffered a gunshot wound to the head before the massive blast, officials said Thursday.

Las Vegas Metropolitan Police Dept. Sheriff Kevin McMahill said at a news conference that a handgun was found at the feet of the man who's been identified as Matthew Livelsberger. Officials believe the shot was self-inflicted.

Livelsberger, an Army soldier from Colorado, served in the Green Berets, highly trained special forces who work to counter terrorism abroad and train partners, the Army said in a statement. He was active duty from January 2006 to March 2011, according to an Army spokesperson. He then joined the National Guard from March 2011 through July 2012. After that, Livelsberger was in the Army Reserve until December 2012, when he entered active duty as an Army Special Operations soldier.

"Livelsberger was assigned to the command and on approved leave at the time of his death. USASOC is in full cooperation with federal and state law enforcement agencies, but as a matter of policy, will not comment on ongoing investigations," the spokesperson said.

He served at the same military base as Shamsud-Din Jabbar, the man suspected of intentionally driving into a crowd in New Orleans, killing 15, but the FBI says there's no definitive link between the two.

McMahill did acknowledge some of the similarities in both cases, such as the use of the Turo app to rent the vehicles in both incidents.

"Both subjects served at Fort Bragg, North Carolina," McMahill said. "What we do know about that is it's a very large military base, and we have no record that they served in the same unit or even [during] the same years."

Both men also served in Afghanistan in 2009, he added, but investigators don't yet know if they were in the same location or the same unit.

Matthew Livelsberger identified as driver in Cybertruck explosion

Livelsberger died and seven others were injured as a result of the explosion at the entrance of the Las Vegas Trump International Hotel on Wednesday morning.

Police said the act was intentional. Gas canisters, camping fuel and firework mortars were found in the bed of the truck after the fire was extinguished, McMahill said.

However, police did not find any devices that would have been used to ignite the explosion, and are unsure at this time how it ignited.

Kenny Cooper, a special agent in charge for the the Bureau of Alcohol, Tobacco, Firearms and Explosives, said at Thursday's press conference that the initial investigation has determined that the fireworks were consumer grade and there is currently no evidence of any fuel enhancers.

“The level of sophistication is not what we would expect from an individual with this type of military experience,” Cooper said.

Among other charred items found inside the truck were a second firearm, a number of fireworks, passport, military ID, credit cards, an iPhone and a smartwatch, McMahill said. Authorities said both guns were purchased legally.

Investigators have not definitively identified the remains as Livelsberger, but the IDs and tattoos on the body “give a strong indication that it’s him,” the sheriff said.

Cybertruck explodes outside Trump Las Vegas hotel

Video footage of the incident shows the truck parked next to the hotel's front doors as it bursts into flames, exploding fireworks visible amid the blast.

McMahill said Thursday that the force of the explosion "sort of vented out and up," and didn't destroy the sides of the vehicle nor the nearby glass doors of the Trump hotel.

"I also know that there's a number of unexploded pieces of the things that he had inside of that vehicle, and so I just don't think that it was done as well as he was expecting," he added.

Authorities said Thursday that Livelsberger rented the Cybertruck in Denver on December 28. Investigators were able to track his movements using information from Tesla charging stations as the vehicle recharged in Monument, Colorado on Dec. 30, then in Trinidad, Colorado; Las Vegas; Albuquerque, New Mexico; and Gallup, New Mexico Dec. 31. On Jan. 1, the Cybertruck was charged in Arizona at stations in Holbrook, Flagstaff and Kingman before it was first spotted in Las Vegas at 7:29 a.m. Wednesday.

"We are heartbroken by the violence perpetrated in New Orleans and Las Vegas, and our prayers are with the victims and families," a Turo spokesperson said in a statement. "We are actively partnering with law enforcement authorities as they investigate both incidents. We do not believe that either renter involved in the Las Vegas and New Orleans attacks had a criminal background that would have identified them as a security threat."

FBI Acting Special Agent-In-Charge Jeremy Schwartz said the car explosion was an isolated incident and that there is no threat to the public.

The draft is three weeks away now. GM Ryan Poles and head coach Ben Johnson have pieced together an off-season that is earning widespread praise across the league. The question is whether they can stick the landing with their 1st round pick in the draft. Current projections have the top three picks likely being a mix of Cam Ward, Travis Hunter, and Abdul Carter. After that, it gets tricky. People in Chicago want to know where running back Ashton Jeanty will end once the dust settles.

Widespread belief has been that the Las Vegas Raiders are the heavy favorites to take him at 6th overall, with New Orleans at #9 also being a possibility. It makes sense. Las Vegas’ best option right now is a 33-year-old Raheem Mostert. New Orleans knows Alvin Kamara turns 30 in July. Both teams need to think about the future at that position. Both have head coaches who like to run the ball. One thing is clear. A source told SM that those around the league believe one thing is certain.

“He likely won’t get passed Chicago if he falls that far.”

Ashton Jeanty is a strong probability for the Bears.

Whispers from Halas Hall indicate they love the Boise State star. It isn’t hard to see why. He nearly broke Barry Sanders’ single-season rushing record in 2024, nearly winning the Heisman in the process. The guy carried his team to the college football playoffs. He’s built like a brick house with power, speed, contact balance, and vision. There aren’t any truly glaring weaknesses in his game. He’s earned comparisons to the likes of LaDainian Tomlinson and Marshawn Lynch. The Bears haven’t had a back of that caliber since Matt Forte.

Try to imagine what this offense could look like with Ashton Jeanty, Rome Odunze, D.J. Moore, and Cole Kmet all as options for quarterback Caleb Williams. Throw all of it into Johnson’s offense, and you can understand why some people around the league aren’t wild about the idea. They are quietly hoping Jeanty goes somewhere else. One thing is certain. If he gets past the Raiders, the noise will get loud in a hurry. It would mark the first time in 20 years the Bears have taken a running back in the 1st round.
