Arrest made in decades-old murder
After more than 35 years, police have arrested a man suspected of killing a woman in Tucson. Tucson police have charged 66-year-old Bruce McCullough with first-degree murder. He is accused 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 said he avoided law enforcement for decades by using a fake identity but recently had been using his own name. Tucson police said McCullough is awaiting extradition to Arizona.
