Heraldo de Madrid - Vegas Tesla blast suspect shot himself in head: officials

Matthew Livelsberger, 37, a member of the elite Green Berets, appears to have committed suicide in the rented vehicle filled with fuel containers and fireworks, which then erupted into flames, officials said.

Livelsberger's body was burned beyond recognition but Las Vegas Sheriff Kevin McMahill said the authorities had "a lot of confidence" that he was the sole occupant of the Cybertruck.

Livelsberger, identified through his military ID, passport and credit cards, had a gunshot wound to the head and a gun was found at his feet, McMahill told reporters at a press conference in Las Vegas.

"The motivation at this point is unknown," FBI Special Agent Spencer Evans said.

Evans said there is "no information that we're aware of right now that connects this individual to any terrorist organization around the world."

Kenny Cooper, a special agent with the Bureau of Alcohol, Tobacco, Firearms and Explosives, said Livelsberger had legally purchased two semi-automatic handguns on Monday which were found in the remains of the vehicle.

Video footage outside the Trump hotel shows the stainless steel truck parked at the building's glass entrance early Wednesday, then bursting into flames, followed by smaller explosions that appeared similar to fireworks.

Seven people were wounded in the blast.

The Trump-branded building, which opened in 2008, is part-owned by the Republican president-elect's family business.

Evans said the link to the president-elect was "not lost" on investigators, nor was the fact that Tesla is owned by world's richest man -- and prominent Trump backer -- Elon Musk.

"But we don't have information at this point that definitively tells us" it was driven by any particular ideology, he said.

Livelsberger rented the vehicle in Colorado on December 28, from where authorities tracked him driving it alone through Arizona and New Mexico to Las Vegas, which he reached on January 1, Kevin McMahill said.

McMahill said Livelsberger was a Green Beret who had been deployed to Afghanistan in 2009 and was currently stationed in Germany.

An army spokesperson said Livelsberger was "on approved leave at the time of his death," and that he had been awarded multiple Bronze Star Medals, including one for valor.

Investigators said it was not yet clear how the blast detonated, but the components were mainly consumer products like fireworks and fuel.

They said some of the components had not exploded, and that the level of sophistication in the blast was not what they would expect from someone with Livelsberger's military background.

"I just don't think it was done as well as he was expecting it to be done," McMahill said.

The blast came just hours after a pickup truck plowed into a crowd of revelers in the French Quarter of New Orleans, killing at least 14 people and injuring dozens.

Initially investigators were probing potential links between the events, but authorities in New Orleans said Thursday they believe the Islamic State-inspired attacker there acted alone, while the FBI described the Vegas incident as "isolated."
