A San Diego man has been arrested in the 1976 killing of a Tucson woman, police say.

Bruce McCullough, 66, had been linked to the slaying since shortly after the body of Donna Smith was found in the midtown home the pair shared. Smith was 20 years old when she was killed, McCullough was 28.

Detectives had reviewed the case several times over the years and each time McCollough was identified as the likely suspect, Sgt. Maria Hawke said in a news release Monday.

McCullough had assumed a new identity, but apparently started using his real name in January. Detectives tracked him to a home in San Diego where he was arrested Thursday.

McCullough has been booked into the Pima County jail on suspicion of murder.
