A girl was found dead at the beach after a bike ride in 1972. DNA helped police identify a suspect

(CNN)An 11-year-old girl went on a bike ride on Thanksgiving Day in 1972. The next day her body was found dumped on a rocky beach near the Pacific Ocean in Southern California. She’d been raped and strangled.
Police conducted more than 2,000 interviews and followed numerous leads but could not identify a suspect in the death of Terri Lynn Hollis until this year. On Wednesday, Torrance police announced a suspect — now dead — has been identified through a match made on a national DNA database.
