From Fox News:
Investigators have yet to determine what drove an active-duty U.S. Army soldier to rent a Tesla Cybertruck and drive it to the Trump International Hotel in Las Vegas, where he appeared to shoot himself in the head before the vehicle exploded New Year’s Day.
Las Vegas Sheriff Kevin McMahill identified 37-year-old Matthew Livelsberger of Colorado Springs, Colorado, as a person of interest in the matter, though he would not say with 100% certainty that Livelsberger is a suspect until DNA matches the remains of a body inside the Cybertruck. His uncle, Dean Livelsberger, told The Independent his nephew “was a 100% patriot” and described him “like a Rambo-type, for lack of a better term.” The Independent reported Dean said his nephew had patriotic subject matter on Facebook and loved President-elect Trump.
