A Tesla Cybertruck that exploded in front of Trump International Hotel Las Vegas, killing one person and injuring seven others, contained gasoline and camp fuel containers, as well as large firework mortars, according to authorities.

Las Vegas Sheriff Kevin McMahill said during a press conference on Wednesday that investigators know who rented the Cybertruck, which was acquired in Colorado, though they are not prepared to identify that person without 100% certainty.

McMahill also said investigators were able to trace the truck through Tesla charging stations. License plate readers in Las Vegas first detected the vehicle at about 7:30 a.m., and McMahill said it traveled up and down Las Vegas Boulevard before pulling into the Trump hotel valet area.

Within 15-20 seconds of pulling up to the hotel, the sheriff added, the vehicle exploded.

The billionaire kept followers up to date about the Cybertruck explosion on his social media platform X.

“We have now confirmed that the explosion was caused by very large fireworks and/or a bomb carried in the bed of the rented Cybertruck and is unrelated to the vehicle itself. All vehicle telemetry was positive at the time of the explosion,” Musk wrote in one post.

“The evil knuckleheads picked the wrong vehicle for a terrorist attack. Cybertruck actually contained the explosion and directed the blast upwards,” he said in another post. “Not even the glass doors of the lobby were broken.”

President Biden also weighed in on the Las Vegas explosion.

“We’re tracking the explosion of a Cybertruck outside the Trump Hotel in Las Vegas,” he said while speaking about the fatal crash in New Orleans. “Law enforcement and the intelligence community are investigating this as well, including whether there’s any possible connection with the attack in New Orleans. Thus far, there’s nothing to report on that score at this time.”
