SAN MATEO CO. (BCN) — A 68-year-old man who was arrested and charged last year with the 1983 sexual assault and murder of a 19-year-old woman whose body was found in Pacifica has been cleared of all charges.

John Scott, 68, of Arizona was released from custody Thursday after his case was dismissed due to insufficient evidence, according to prosecutors.

“He submitted to extensive DNA analysis and was cleared,” defense attorney Brian Getz said.

On Oct. 30, 1983, two sightseers found the body of San Francisco Sharon Ray on a beach north of Pescadero Creek Road. She had been sexually assaulted and strangled, according to prosecutors.

Ray was last seen the day before she was found dead in San Francisco’s Tenderloin neighborhood, getting into a station wagon.

Investigators determined Scott, who was 35 years old at the time, matched the description of the station wagon driver. He was arrested as a suspect in her murder but later released because there was insufficient evidence to prosecute him at the time, prosecutors said.

Back in February investigators reopened the decades old murder case after the sheriff’s office’s forensic lab was able to analyze DNA found on Ray.

When the DNA evidence did not match any in a national database, investigators obtained Scott’s DNA evidence from a Gatorade bottle. The evidence garnered a tentative positive match to the fluid found on Ray, according to prosecutors.

Scott was arrested on Nov. 16 in Topock, Arizona, where he was living at the time. Scott was then extradited from Arizona to face charges in San Mateo County for murder.

Although Scott is no longer a suspect in Ray’s murder, Getz said the outcome was no victory. “It’s never a victory, when an innocent person like Sharon Ray dies and they don’t know who did it,” Getz said.
