The brutal 1984 killing of a teenager at Torrey Pines State Beach has apparently been solved through DNA and an extensive investigation, the San Diego Police Department announced Thursday.

Both suspects in the strangulation and mutilation of 14-year-old Claire Hough are dead, the police said. Both were linked through DNA.

The teenager was in San Diego visiting her grandparents from her home in Rhode Island when she was found dead.
