Las Vegas police found two letters in the Cybertruck left behind by Matthew Livelsberger, the suspect in the Las Vegas Cybertruck explosion outside Trump Hotel.

These letters contained statements suggesting that the incident was not meant to be a terrorist attack but rather a "wake-up call" for what he perceived as weak leadership and a country he described as "terminally ill" and heading towards collapse.

Podcaster Shawn Ryan claimed he is going into hiding following the release of his most recent episode where he shares an email allegedly sent by Livelsberger before the Cybertruck explosion incident. Guest Sam Shoemate said he was sent an email on Tuesday from Livelsberger.

"On December 31st, Sam received an email allegedly from Matthew Livelsberger -- who would be named as the perpetrator in the detonation of a Tesla Cybertruck at Trump Tower the following day," Ryan said on the podcast.

Here is what the email said, according to Shoemate:

"In case I do not make it to my decision point or on to the Mexico border I am sending this now. Please do not release this until 1JAN and keep my identity private until then.

"First off I am not under duress or hostile influence or control. My first car was a 2006 Black Ford Mustang V6 for verification.

"What we have been seeing with 'drones' is the operational use of gravitic propulsion systems powered aircraft by most recently China in the east coast, but throughout history, the US. Only we and China have this capability. Our OPEN location for this activity in the box is below.

"China has been launching them from the Atlantic from submarines for years, but this activity recently has picked up. As of now, it is just a show of force and they are using it similar to how they used the balloon for sigint and isr, which are also part of the integrated coms system. There are dozens of those balloons in the air at any given time.

"The so what is because of the speed and stealth of these unmanned AC, they are the most dangerous threat to national security that has ever existed. They basically have an unlimited payload capacity and can park it over the WH if they wanted. It's checkmate.

"USG needs to give the history of this, how we are employing it and weaponizing it, how China is employing them and what the way forward is. China is poised to attack anywhere in the east coast

"I've been followed for over a week now from likely homeland or FBI, and they are looking to move on me and are unlikely going to let me cross into Mexico, but won't because they know I am armed and I have a massive VBIED. I've been trying to maintain a very visible profile and have kept my phone and they are definitely digitally tracking me.

"I have knowledge of this program and also war crimes that were covered up during airstrikes in Nimruz province Afghanistan in 2019 by the admin, DoD, DEA and CIA. I conducted targeting for these strikes of over 125 buildings (65 were struck because of CIVCAS) that killed hundreds of civilians in a single day. USFORA continued strikes after spotting civilians on initial ISR, it was supposed to take 6 minutes and scramble all aircraft in CENTCOM. The UN basically called these war crimes, but the administration made them disappear. I was part of that cover-up with USFORA and Agent [Redacted] of the DEA. So I don't know if my abduction attempt is related to either. I worked with GEN Millers 10 staff on this as well as the response to Bala Murghab. AOB-S Commander at the time. [Redacted] can validate this.

"You need to elevate this to the media so we avoid a world war because this is a mutually assured destruction situation.

"For vetting my Linkedin is Matt Berg or Matthew Livelsberger, an active duty 18Z out of 1-10 my profile is public. I have an active TSSCI with UAP USAP access."

Additionally, one of the letters mentioned his intent to "cleanse my mind of the brothers I've lost and relieve myself of the burden of the lives I took," indicating a personal motive related to his experiences as a soldier.

In another development, Livelsberger's ex-girlfriend reportedly shared with the FBI, text messages she received from him just days ago playfully bragging about his rented Tesla Cybertruck.

Alicia Arritt and Livelsberger dated from 2018 to 2021, but she told The Denver Gazette it was odd he reached out three days before the New Year's Day explosion outside President-elect Trump's Las Vegas hotel. 

They reportedly 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 they had both moved on. 

"I just want everyone to know that Matt was the kindest man I ever knew," Arritt reportedly said, explaining that Livelsberger bought her a house when her mother became ill. "He got me through a difficult time." 

The FBI showed up at Arritt's door in Colorado Springs 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 the agents how Livelsberger messaged her Dec. 29 photos and music videos of the gold Cybertruck he rented.

"I rented a Tesla Cybertruck. It’s the shit," he wrote her at 9 a.m. Sunday, according to the Gazette.

"It matches my Kobe 2 shoes 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 to death inside the Cybertruck loaded with explosives moments before it detonated outside Trump's hotel in Las Vegas New Year's morning. 

Arritt described Livelsberger as an honorable man who loved his country and that she knew him to be politically conservative. Livelsberger's family has reportedly described him as a supporter of Trump. 

She also said Livelsberger had two surgeries on his back after serving 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 became isolated, explaining she thinks his depressive symptoms went untreated because "it’s not acceptable to seek treatment when someone is in Special Forces."

They broke up partly because "he wanted to focus on his career," she said.

"I don’t know if I could have stopped him," she reportedly said.

Arritt previously served as an Army nurse at Landstuhl Regional Medical Center in Germany.

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

After their three-year relationship, Livelsberger remarried. His second wife, Jennifer Davis, reportedly broke up with Livelsberger six days before the attack. She reportedly accused him of cheating on her around the time she gave birth to their infant daughter. He left their home in Colorado Springs the day after Christmas after a fight.
