Watch: Explosion in Cybertruck outside Trump hotel The Las Vegas Metropolitan Police Department provided updates and released this footage after an explosives-laden Cybertruck burned outside the front doors of the Trump International Hotel in Las Vegas on New Year’s Day. Authorities released a journal Livelsberger kept titled "surveillance" or "surveil" log. It showed that Livelsberger believed he was being tracked by authorities, but he had no criminal record and was not on the police department's or FBI's "radar." Citing police, the AP noted that the journal showed that Livelsberger thought about conducting his plans in Arizona at the Grand Canyon's glass skywalk, a tourist attraction on tribal land that towers high above the canyon floor. According to officials, the journal also showed that Livelsberger was concerned that he would be labeled a terrorist, and that people would think he planned to kill others besides himself. The AP reported that a video showed a flash in the truck that police said they think came from the muzzle of the gun Livelsberger used to shoot himself. Following the flash, video captured fire overwhelming the Cybertruck. An explosion then followed. Who was Matthew Livelsberger? Matthew Livelsberger, an Army Green Beret who deployed twice to Afghanistan and lived in Colorado Springs, Colorado, left notes saying the explosion was a stunt meant to be a "wake up call" for the nation's troubles, officials said last week. According to the AP, Livelsberger left cellphone notes saying he needed to "cleanse" his mind "of the brothers I’ve lost and relieve myself of the burden of the lives I took." Livelsberger’s letters described political complaints, societal problems, and domestic and international issues, including the war in Ukraine. He wrote that the U.S. was "terminally ill and headed toward collapse." His letter didn’t express ill will toward President-elect Donald Trump, law enforcement officials shared with the AP. In one of the notes Livelsberger left, he said the country needed to "rally around" Trump and Tesla CEO Elon Musk.
