The exposition of a Tesla Cybertruck outside a Trump property in Las Vegas on New Year’s Day is now believed to be the result of suicide by an Army service member who had been struggling with Post-Traumatic Stress Disorder (PTSD), according to the FBI.

Federal and local police identified Matthew Alan Livelsberger, an active-duty member of the Army Special Forces, as the perpetrator of an explosion outside the Trump International Hotel early Wednesday.
