Detectives are still working to solve the death of a young woman whose body was found unclothed on the side of an East Bay road more than 37 years ago.

Dana Ramm, a graduate of Granada High School in Livermore, was found dead on Dec. 29, 1986, on Andrade Road in Sunol, according to the Alameda County Sheriff’s Department.

The 20-year-old woman had been strangled, authorities said. She was last seen alive the night before at a Chevron gas station at the corner of Valley Avenue and Santa Rita Road in Pleasanton.

Ramm was with two acquaintances in a brown Oldsmobile that had run out of gas, and she waited alone in the car while they went to get money to buy gas, the sheriff’s office said.

When they returned, she was gone.

“There hasn’t been a single day in the past 20 years that she hasn’t popped into my mind,” Dana’s mother, Georgia Ramm, was quoted saying in an undated Sacramento Bee article from the early 2000s. “Maybe there’s something that triggers a memory, or maybe not. I think about her and ask God to take care of her.”

Although Ramm’s case has remained unsolved for decades, detectives have not given up trying to find her killer or killers. In 2008, her image was featured along with 12 other victims of unsolved cases in a deck of playing cards produced by the sheriff’s office and distributed to inmates at Santa Rita Jail in Dublin, the hope being that someone might provide them a credible lead in the case.

Anyone with information about the case is asked to call the sheriff’s cold case investigators at 510-667-3661. To remain anonymous, information may be submitted via the anonymous tip line at 510-667-3622.
