Matthew Livelsberger mostly bore that burden in private but recently sought treatment for depression from the Army, according to a U.S. official.

Master Sgt. Matthew Livelsberger, an active duty Green Beret for almost 20 years, shot himself just before the truck exploded, police said.

Police say the suspect behind the Tesla Cybertruck explosion outside Trump Hotel in Las Vegas was an active-duty member of the U.S. Army’s special forces stationed in Germany.
