Livelsberger confided to a former girlfriend – who had served as an army nurse – that he faced significant pain and exhaustion that she says were key symptoms of traumatic brain injury.

Traumatic brain injury
Livelsberger was a five-time Bronze Star recipient, including one with a V device for valour 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 the texts, he opened up about exhaustion, pain that kept him awake at night and reliving violence from his deployment in Afghanistan.
“My life has been a personal hell for the last year,” he said to Arritt during the early days of their dating, according to text messages she provided to the Associated Press. “It’s refreshing to have such a nice person come along.”
Arritt also served on active duty in the army as a nurse from 2003 to 2007, deploying to the military’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.
“He would go through periods of withdrawal, and he struggled with depression and memory loss,” Arritt said. “He said it was a blast injury. He got several concussions from that.”
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.
“I would encourage him to get therapy, and he would give me reasons that he couldn’t,” Arritt said. “There 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.”
The new details came as investigators sought to determine Livelsberger’s motive, including whether he sought to make a political point with the Tesla and the hotel bearing the president-elect’s name.
Tesla chief executive Elon Musk has recently become a member of the president-elect’s inner circle. Neither Trump nor Musk was in Las Vegas early on Wednesday, the day of the explosion. Both attended Trump’s New Year’s Eve party at his Florida estate.
Musk spent an estimated $US250 million during the presidential campaign to support Trump, and Trump has named Musk, the world’s richest man, to co-lead a new effort to find ways to cut the government’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.
Investigators know that a highly decorated army soldier shot himself inside a Tesla Cybertruck packed with fireworks just before it exploded outside the Trump International Hotel on New Year’s Day, but authorities say there are questions about why he chose that car and location.

“It’s not lost on us that it’s in front of the Trump building, that it’s a Tesla vehicle, but we don’t have information at this point that definitively tells us or suggests it was because of this particular ideology,” Evans, the Las Vegas FBI’s special agent in charge, said on Thursday.
Asked on Friday about whether Livelsberger had struggled with any mental health issues that may have prompted his suicide, Pentagon spokeswoman Sabrina Singh told reporters that “the department has turned over all medical records to local law enforcement”.
A law enforcement official said investigators learnt through interviews that Livelsberger may have been in a fight with his wife about relationship issues shortly before he rented the Tesla on Saturday and bought the guns. The official spoke on the condition of anonymity because they were not authorised to discuss the investigation.

“The level of sophistication is not what we would expect from an individual with this type of military experience,” said Kenny Cooper, a special agent in charge from the Bureau of Alcohol, Tobacco, Firearms and Explosives.
Authorities are still working to determine a motive. Among the charred items found inside the truck were a handgun at Livelsberger’s feet, another firearm, fireworks, a passport, a military ID, credit cards, an iPhone and a smartwatch, McMahill said. Authorities said both guns were purchased legally.
Livelsberger served in the Green Berets, highly trained special forces who work to counter terrorism abroad and train partners. He had served in the army since 2006, rising through the ranks with a long career of overseas assignments, deploying twice to Afghanistan and serving in Ukraine, Tajikistan, Georgia and Congo, the army said. He had recently returned from an overseas assignment in Germany and was on approved leave when he died, according to a US official.

Authorities searched a townhouse in Livelsberger’s hometown on Thursday as part of the investigation. Neighbours said the man who lived there had a wife and a baby.
Cindy Helwig, who lives diagonally across a narrow street separating the homes, said she last saw the man she knew as Matthew about two weeks ago when he asked her if he could borrow a tool he needed to fix an SUV he was working on.
“He was a normal guy,” said Helwig, who said she last saw the wife and baby earlier this week.
