Law enforcement discovered a cache of weaponry and armor, including a machine gun and grenade launchers, along with Nazi paraphernalia during a raid of a home in Washington state, authorities said Tuesday.

Derek Sanders, the elected sheriff of Thurston County, said in a Facebook post that the U.S. Army Criminal Investigation Division asked his office for assistance Monday as an FBI special weapons and tactics team executed a search warrant in Lacey, near the state capitol of Olympia, “as a result of a violent robbery and theft of military weaponry/armor.”
