A Keokuk County sheriff's deputy was shot and killed by a man who was later shot to death by a state tactical unit, authorities said late Monday.
Deputy Eric Stein, 38, of What Cheer had been with the sheriff's office since 2000.
The last time an Iowa law officer died by gunfire while on duty was in 1985.
Stein, Sheriff Jeff Shipley and Deputy Casey Hinnah approached the home of Jeffrey Alan Krier, 53, near Sigourney shortly before noon Monday, officials said. When they arrived, Krier opened fire. Stein was hit and died of his wounds at the scene. Shipley and Hannah were unhurt.
The trio had gone to the house because of an unspecified incident that reportedly occurred Sunday night. No further details were provided.
About three hours later, after a standoff, Krier exited his home armed with weapons, was shot by an Iowa State Patrol tactical unit and died at the scene, officials said. Authorities did not say what weapons Krier had or whether he threatened other officers.
