Jeffrey David Borthwick was 19 when he was last seen at his San Francisco home on April 30, 1982. Described as 6 feet 1 inch, 145 pounds, with brown hair, blue eyes and known to wear eyeglasses, he may have been wearing blue jeans and a t-shirt when he disappeared. Jeffrey had a mental disability and his case is classified as endangered missing.

Few public details are available and investigators have not been able to solve the case. Foul play has not been ruled out, but there is little evidence to explain what happened and the disappearance remains unsolved more than four decades later.

If anyone knew Jeffrey, saw him around April 30, 1982, or has information that could help the San Francisco Police Department, please come forward.
