Matthew Livelsberger, who was inside the Tesla Cybertruck that exploded outside President-elect Donald Trump's Las Vegas hotel on Wednesday, allegedly warned of a coming "world war" in an emailed manifesto one day earlier. Retired Army intelligence officer Sam Shoemate said during an episode of the Shawn Ryan Show podcast released on Friday that he received an email from Livelsberger on December 31. It urged him to warn the public that "gravitic" technology used by the U.S. and China was a "mutually assured destruction situation" that could bring about World War III. “fellow service members, veterans and all Americans” it’s time to “wake up” because the country’s leadership is “weak” and “only serves to enrich themselves.” A second letter appeared to shed more light on Livelsberger’s thinking. “We are the United States of America, the best country ... to ever exist, but right now, we are terminally ill and headed towards collapse,” a second letter said. “This was not a terrorist attack. It was a wake up call. Americans only pay attention to spectacles and violence. What better way to get my point across than a stunt with fireworks and explosives. ... I need to cleanse my mind of the brothers I’ve lost, and relieve myself of the burden of the lives I took.” Spencer Evans, special agent in charge of the FBI’s Las Vegas division, added that the investigation along with a consultation with the Army determined that Livelsberger likely had post-traumatic stress disorder, and that investigators are aware that there were potential “family issues or personal grievances in his own life that may have been contributing factors.” #swpg southwest prepper group
