Tesla Cybertruck attacker in Las Vegas identified as decorated Green Beret: What was his motive? Authorities have tentatively identified the man killed inside a Tesla Cybertruck outside the Trump hotel in Las Vegas as 37-year-old Matthew Livelsberger. Here’s what we know. Jan. 3, 2025 Among other writing excerpts released Friday were passages in which Livelsberger expressed frustration with the nation’s direction. “Fellow servicemembers, veterans and all Americans. TIME TO WAKE UP! We are being led by weak and feckless leadership who only serve to enrich themselves.” He also wrote that that the United States was the best country “to ever exist! But right now we are terminally ill and headed toward collapse.” Advertisement Livelsberger served as a Green Beret master sergeant in the Army. He spent the majority of his time at Ft. Carson in Colorado and in Germany, according to authorities. He was on approved leave from Germany at the time of his death. On his Facebook profile, Livelsberger once criticized the withdrawal of U.S. armed forces from Afghanistan in 2021. He called it the “biggest foreign-policy failure in the history of the United States.” At Friday’s news conference, authorities stressed that their investigation into Livelsberger is continuing, and that their view of the incident could change, as they still had more of the dead man’s writings to examine, as well as other information. “We have terrabytes of data that we have to analyze,” Evans said. However, after conducting numerous interviews with family members, friends and military colleagues, investigators have concluded that Livelsberger held no animosity toward Trump. “Although 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 is struggling with PTSD and other issues,” Evans said. Times staff writers Summer Lin, Hannah Fry, Richard Winton and Terry Castleman contributed to this report. More to Read
