Matthew Livelsberger was a 37-year-old army veteran from Colorado Springs. Sources told Denver 7 that multiple addresses had been associated with Livelsberger in Colorado and FBI agents were investigating these properties. According to a family member, who spoke exclusively to The Independent, Livelsberger “was a 100 percent patriot,” who loved the Army and was an ardent supporter of President-elect Donald Trump. Pictures from social media show him with a tattoo of a bald eagle and the American flag visible on his shoulder. “He used to have all patriotic stuff on Facebook, he was 100 percent loving the country,” his uncle, Dean Livelsberger, said. “He loved Trump, and he was always a very, very patriotic soldier, a patriotic American. It’s one of the reasons he was in Special Forces for so many years. It wasn’t just one tour of duty.” open image in gallery Multiple addresses had been associated with Livelsberger in Colorado Springs, Colorado, and FBI agents were investigating these properties (AP) Livelsberger divorced his first wife, who now lives in South Florida with her new husband, several years ago. He had a newborn with his second wife, who reportedly ended their relationship just days before the explosion. He had argued with his wife after she told him she suspected he had been cheating, the New York Post reported, citing law enforcement sources. Livelsberger left his home in Colorado Springs the day after Christmas following the argument with his wife, two sources familiar with the investigation told the newspaper. It has also emerged that Livelsberger had reportedly been back in touch with former girlfriends in the days before the explosion. open image in gallery Flames rise from a Tesla Cybertruck after it exploded outside the Trump International Hotel Las Vegas on January 1 (Alcides Antunes/Reuters) He boasted to one of them, Alicia Arritt, that he “felt like Batman” after renting the Tesla Cybertruck. Arritt, from Colorado Springs, his former girlfriend of three years, said the 37-year-old got in touch with her on December 29 out of the blue. “I rented a Tesla Cybertruck. It’s the s***,” he texted Arritt that morning, the Denver Gazette reports. “I feel like Batman or halo,” he added. According to Arritt, Livelsberger’s behavior changed after he returned from a tour in the Middle East suffering from a traumatic brain injury in 2019. Chilling notes recovered on his phone: Explosion was ‘a wake up call’ At a press conference on Friday afternoon, Coren of the Las Vegas Metropolitan Police shared excerpts from notes investigators found on Livelsberger’s phone following the explosion. They provided an insight into his state of mind before he detonated the vehicle, according to officials. “Fellow Servicemembers, Veterans, and all Americans, TIME TO WAKE UP!” he said in one excerpt. “We are being led by weak and feckless leadership who only serve to enrich themselves.” In a second letter, Livelsberger said the US is “headed toward collapse.” “This was not a terrorist attack, it was a wake up call,” Livelsberger said. “Americans only pay attention to spectacles and violence. What better way to get my point across than a stunt with fireworks and explosives?” He added: “Why did I personally do it now? I needed to cleanse my mind of the brothers I’ve lost and relieve myself of the burden of the lives I took.” Coren added that the words he read aloud were only excerpts of more letters they uncovered, which he said would be made public. He explained that Livelsberger wrote about “political grievances, issues about conflicts elsewhere, domestic issues” and “a variety of things including personal challenges.” Where did he serve?
