An ex-girlfriend of the Las Vegas explosion suspect has reportedly shared with the FBI text messages she received just days ago from Matthew Livelsberger in which she jokingly bragged about his rented Tesla Cybertruck.

Alicia Arritt and Livelsberger were together from 2018 to 2021, but she told the Denver Gazette it was strange that he came forward three days before the New Year’s explosion outside President-elect Trump’s hotel in Las Vegas.

She told the newspaper they met in 2018 after Livelsberger divorced his first wife, Sara. But Arrit said she and Livelsberger stopped talking after a painful breakup in 2021 and have both moved on.

“I just want everyone to know that Matt was the nicest man I ever knew,” Arritt told the Gazette, explaining that Livelsberger bought her a house when her mother became ill. “He helped me through a difficult time.”

The FBI showed up at Arritt’s door in Colorado Springs on the evening of New Year’s Day after tracking messages from Livelsberger’s account, but she was at work, according to the Gazette.

FBI agents returned Thursday morning and met with her at 9 a.m., she said.

She showed agents how Livelsberger sent her photos and music videos of the gold Cybertruck he had rented on Dec. 29.

“I rented a Tesla Cybertruck. This is the shit,” he texted her at 9 a.m. Sunday, according to the Gazette.

“It matches my Kobe 2 shoes that I had when I was little,” Livelsberger added. “Google them.

“I feel like Batman or Halo.”

Arritt said she was unaware of Livelsberger’s plans to allegedly shoot himself in the explosives-laden Cybertruck shortly before it exploded outside Trump’s Las Vegas hotel on New Year’s morning.

Arritt described Livelsberger as an honorable man who loved his country and she knew he was politically conservative. Livelsberger’s family has reportedly described him as a Trump supporter.

She also said Livelsberger underwent two back surgeries after his deployment as a paratrooper. She said she noticed a change in him in 2019 after he returned from a tour in the Middle East with a traumatic brain injury. She said Livelsberger was isolated and told the newspaper she believed his depressive symptoms went untreated because “it’s not acceptable to seek treatment when someone is in a special unit.”

They separated in part because “he wanted to focus on his career,” she said.

The Gazette said Arritt burst into tears when he heard investigators identified Livelsberger from a tattoo of a World War I aircraft on his right arm.

“I don’t know if I could have stopped him,” she reportedly told the newspaper.

According to the Gazette, Arritt previously served as an Army nurse at Landstuhl Regional Medical Center in Germany.

Livelsberger was a Green Beret who served in the military for 19 years, primarily at Fort Carson and on assignment in Germany.

Arritt shared a photo of her with a wildflower in her hair while Livelsberger smiled behind her.

She said the picture was taken while the two were attending a “spy school” in Washington state, the Gazette said.

After their three-year relationship, Livelsberger married again. His second wife, Jennifer Davis, reportedly separated from Livelsberger six days before the attack.
