Thieves cut through padlocks and latches to filch 12,000 rounds of ammunition from a decommissioned military base in southwest Washington now used as a shooting range by the FBI and other law enforcement agencies, deputies said Monday. The rounds of 9 mm and rifle ammo were discovered stolen from a storage shed at Camp Bonneville on Jan. 15 — about two weeks since deputies had last visited the remote training facility, said Clark County Sheriff’s Sgt. Chris Skidmore.
