20-year-old Donna Smith was found dead in her apartment in March of 1976. On May 2, the man suspected of murdering her, 66-year-old Bruce McCullough was found and arrested by Tucson Police in San Diego.

McCullough, who was 28 at the time of Smith's murder, was Smith's live-in-boyfriend who disappeared shortly after Smith's death. He became the prime suspect in the murder, a conclusion that TPD homicide and cold case detectives reached in each review of the case.

TPD caught a break this year though, as it appears that McCullough slipped up and began using his old identity again after decades of using an assumed identity, and was tracked down to San Diego.

From TPD:

Ultimately, Mr. McCullough was arrested and charged with 1 count of First Degree Murder, a felony offense, pursuant to a warrant that had been issued for his arrest. He was transported and booked into the San Diego Jail as a Fugitive from Justice and is awaiting extradition to Tucson, Arizona. Tucson Police Department detectives also located Ms. Smith’s elderly mother, who still resides within Arizona, and personally visited her, delivering the news that her daughter’s killer had been located and brought to justice.
