A soldier who died in an explosion of a Tesla Cybertruck at the Trump hotel in Las Vegas left a note saying it was a stunt to serve as โ€œwakeup callโ€ for the countryโ€™s ills, investigators said Friday.

This passport belonging to Matthew Livelsberger was found inside a Tesla Cybertruck involved in an explosion Wednesday outside the Trump Hotel in Las Vegas.

Matthew Livelsberger, a 37-year-old Green Beret from Colorado Springs, Colorado, apparently harbored no ill will toward President-elect Donald Trump, Clark County sheriffโ€™s officials said.

Livelsberger wrote in the note that he needed to โ€œcleanse my mindโ€ of the lives lost of people he knew and โ€œthe burden of the lives I took.โ€

โ€œAlthough this incident is more public and more sensational than usual, it ultimately appears to be a tragic case of suicide involving a heavily decorated combat veteran who was struggling with PTSD and other issues,โ€ FBI Special Agent In Charge Spencer Evans said at a news conference.

The explosion Wednesday caused minor injuries to seven people but virtually no damage to the hotel.

โ€œThis was not a terrorist attack, it was a wakeup call. Americans only pay attention to spectacles and violence. What better way to get my point across than a stunt with fireworks and explosives,โ€ Livelsberger wrote in a letter found by authorities who released only excerpts of it.

Investigators identified the Tesla driver โ€” who was burned beyond recognition โ€” as The Clark County coronerโ€™s office said his death was a suicide caused by the gunshot wound.

Clark County Sheriff Kevin McMahill updates the media Thursday at Metropolitan Police Department headquarters in Las Vegas regarding the Tesla Cybertruck that exploded at the Trump International Hotel.

Soldier told ex-girlfriend of pain, exhaustion after Afghanistan

Pentagon officials declined to say whether Livelsberger may have suffered from mental health issues but said they turned over his medical records to police.

Livelsbergerย confided to a former girlfriend โ€” who served as an Army nurse โ€” that he faced significant pain and exhaustion that she says were key symptoms of traumatic brain injury.

Livelsberger was a five-time Bronze Star recipient, including one with a V device for valor under fire. He was very private but shared images and texts with Alicia Arritt, 39, who he met and began dating in Colorado in 2018. In them he opened up about exhaustion, pain that kept him awake at night and reliving violence from his deployment in Afghanistan.

โ€œMy life has been a personal hell for the last year,โ€ he told Arritt during the early days of their dating, according to text messages she provided to the AP. โ€œItโ€™s refreshing to have such a nice person come along.โ€

Arritt also served on active duty in the Army as a nurse from 2003 to 2007, deploying to the militaryโ€™s massive medical complex in Germany where she helped treat many soldiers with traumatic brain injuries and blast injuries from intense ground combat in Afghanistan and Iraq.

She said the military failed to get Livelsberger the care he needed, symptoms she saw in him as early as 2018.

โ€œHe would go through periods of withdrawal, and he struggled with depression and memory loss,โ€ Arritt said. โ€œHe said it was a blast injury. He got several concussions from that.โ€

Livelsberger also had a hard time with post-traumatic stress disorder and would relive some of the violence and killings he had a role in or witnessed in Afghanistan.

โ€œI would encourage him to get therapy, and he would give me reasons that he couldnโ€™t,โ€ Arritt said. โ€œThere was a lot of stigma in his unit, they were, you know, big, strong, Special Forces guys there, there was no weakness allowed and mental health is weakness is what they saw.โ€

The new details came as investigators sought to determine Livelsbergerโ€™s motive, including whether he sought to make a political point with the Tesla and the hotel bearing the president-electโ€™s name.

Tesla CEO Elon Musk recently became a member of President-elect Donald Trumpโ€™s inner circle. Neither Trump nor Musk was in Las Vegas early Wednesday, the day of the explosion. Both attended Trumpโ€™s New Yearโ€™s Eve party at his South Florida estate.

Musk spent an estimated $250 million during the presidential campaign to support Trump, who named Musk, the worldโ€™s richest man, to co-lead a new effort to find ways to cut the governmentโ€™s size and spending.

Investigators suspect Livelsberger may have been planning a more damaging attack but the steel-sided vehicle absorbed much of the force from the crudely built explosive.

The explosion of the truck, packed with firework mortars and camp fuel canisters, came hours after 42-year-old Shamsud-Din Bahar Jabbar rammed a truck into a crowd in New Orleansโ€™ famed French Quarter early on New Yearโ€™s Day, killing at least 14 people before being shot to death by police. The FBI said it believes Jabbar acted alone and that incident is being investigated as a terrorist attack.

Chris Raia, FBI deputy assistant director, said Thursday that officials found โ€œno definitive linkโ€ between the New Orleans attack and the truck explosion in Las Vegas.
