NORTH BEND, Wash. (AP) - The King County sheriff's office in Washington state says a woman stabbed an intruder to death at a North Bend home. Sgt. Cindi West says the woman's husband was struggling with the man about 1:40 a.m. Monday when she got a knife and stabbed the stranger to help her husband. The couple was not injured. West says the intruder is probably the same man who went to the home Sunday afternoon - just 12 hours earlier - walked in through an unlocked door, hit the woman and escaped with cash. Investigators say it apparently was a random attack. They don't know why the house was targeted or why the robber went back.
