REDDING, Calif. (AP) - Investigators are reopening the 37-year-old unsolved murder case of a Northern California teenage girl because of advances in DNA technology. Redding police say investigators sent material to the California Department of Justice DNA lab for testing, and hope it will help them identify a suspect into the 1976 slaying of 15-year-old Terri Lynn Ray. Ray was stabbed multiple times, her body found near a creek off Highway 273. The case took an odd turn in 1976, when police arrested an 18-year-old girl on suspicion of the murder after she confessed under hypnosis. The girl was later freed from Shasta County Jail after a judge threw out the hypnosis-induced confession and police learned she had an alibi.
