On July 8, 1976, 15-year-old Terri Lynn Ray of Redding, California, was found murdered at a popular swimming spot in Clear Creek near her home. She had been stabbed 15 times; many wounds were on her arms, indicating defensive injuries. Neighbors last saw her the day before walking her dog toward Clear Creek, and the dog returned home that night wet and alone. Her body was discovered the next day by children swimming in the area.

Investigators never found the knife, and the exact place of death remained uncertain. Only a small bloodstain on a rock was recovered as physical evidence. The case produced several leads that did not hold up: a 17-year-old boy was briefly detained and released, and an 18-year-old woman confessed under hypnosis but was later released when a credible alibi emerged; that hypnosis-based confession later became cited as an example of the method’s unreliability. Over the years some suspected links to Darrell Rich were raised, but he never confessed and no conclusive evidence tied him to Terri’s death. The case remains unsolved.

Did anyone who knew Terri or who frequented Clear Creek in 1976 have observations that could still help investigators?
