TUCSON, AZ - Investigators in Arizona have arrested a man suspected of killing a woman in Tucson more than 35 years ago.
Tucson police say 66-year-old Bruce McCullough has been charged with first-degree murder in the March 1976 death of 20-year-old Donna Smith. Authorities say the two had been living together as a couple.
Detectives reviewing cold cases were able to track McCullough to San Diego and arrested him at his home last week. They say he avoided law enforcement for decades by using a fake identity but recently had been using his own name.
Tucson police say McCullough is awaiting extradition to southern Arizona.
Detectives say they've visited Smith's mother to let her know of McCullough's arrest.
