Pamela Dawn Tinsley, 19, disappeared from Lake Overholser in Oklahoma City on April 13, 1986. She had been with friends and reportedly accepted a motorcycle ride from a man she had just met, leaving her purse, car, and cigarettes behind and expecting a short return. She was last seen in a two-piece turquoise bathing suit with black polka dots, white shorts, and flip-flop sandals. The motorcyclist was described as a white male in his twenties with brown hair; he has never been identified.

In the weeks before her disappearance Pamela was engaged to a man in the military and dealing with trouble at her Edmond apartment, including three unemployed roommates she wanted to evict and police finding marijuana growing there, which she denied. Investigators considered a possible drug connection after learning her fiancé had asked her to send him drugs; the initial theory that she ran off with the motorcyclist later shifted toward foul play. Anonymous calls to authorities in 2008 named a suspect and a general location for a body, but the lead could not be substantiated. The case remains unsolved; Pamela’s family believes she would not have left voluntarily without her belongings.

Did anyone in the Lake Overholser area on April 13, 1986, or anyone who knew Pamela in Edmond, ever hear or see anything that could help?
