New videos paint a clearer picture of the Trump Hotel Cybertruck explosion in Las Vegas

Two new videos have been released regarding Wednesday’s Cybertruck explosion outside the Trump International Hotel in the Las Vegas as investigators try to piece together what led an active-duty US Army soldier to kill himself and then blow up an electric pickup truck.

The first video shows Tesla Cybertruck slowly leaving the hotel’s service area earlier in the morning, while another video was taken from inside the hotel and shows the truck exploding, sending flames and fireworks into the air.

Investigators believe Matthew Livelsberger, 37, shot himself in the head before blowing up a futuristic-looking truck outside the iconic hotel, sending flames, fireworks and shrapnel into the air just steps from the hotel’s glass doors.

Livelsberger was the only fatality, although seven bystanders reported minor injuries. A motive has yet to be determined. The cause of death was a suicide by gunshot, according to the Clark County Coroner.

The first video is from a surveillance camera and shows who police say is Livelsberger slowly driving a rented Cybertruck out of the hotel’s valet area. Clark County Sheriff Kevin McMahill says Livelsberger then visited several locations along the Las Vegas Strip, including a stop at a company parking lot near the Flamingo Hotel.

In another clip, the truck is stopped at traffic lights at Sands Avenue, then Livelsberger turns right onto Trump International, where it finally stops outside the front gate and 17 seconds later the truck is on fire.

Authorities say the truck contained gasoline and fuel tanks, as well as large firework mortars. The explosion happened just a few steps from the hotel’s glass doors, which were not damaged.

Another video, taken by a witness in the hotel lobby, shows the truck in flames after the initial explosion. In the hotel, an alarm can be heard going off and emergency lights flashing.

Two explosive blasts are heard, followed by the sound of fireworks, then another explosion as the top of the truck remains on fire. The incident happened around 8:40 a.m. local time.

Among the burned items found in the truck were a handgun at Livelsberger’s feet, other firearms, a number of fireworks, a passport, military ID, credit cards, an iPhone and a smartwatch, McMahill said. Authorities said both guns were purchased legally.

Livelsberger was a US Army special operations soldier who had several addresses associated with him and was on leave from Germany, where he was serving with the 10th Special Forces Group.

Kenny Cooper, special agent in charge of the Bureau of Alcohol, Tobacco, Firearms and Explosives, said the level of sophistication is not what officials would expect from an individual with this type of military experience.

Meanwhile, FBI Special Agent Spencer Evans added that investigators are looking into the potential terrorist connections Livelsberger, but had not found him until Thursday afternoon.

“The question of whether it’s being investigated globally, absolutely — as I said, we have investigative leads around the world,” he told reporters. “There is no information that we know of at this time that links this individual to any terrorist organization worldwide, but that is clearly the thrust of the investigation … to rule out any connection to terrorism.”

An Army spokesman told Fox News that Livelsberger entered active duty at army in January 2006 and attained the rank of sergeant.

Livelsberger spent some time at the base formerly known as Fort Bragg, a huge military base in the North Carolina where the Army Special Forces Command is located.

Livelsberger joined the National Guard from March 2011 to July 2012, followed by a stint in the Army Reserve from July 2012 to December 2012. Furthermore, the US Army Special Operations Command confirmed that Livelsberger was on authorized leave at the time of his death .
