Pamela Dawn "Pam" Tinsley was a young woman who went missing in 1986 under suspicious circumstances.
Tinsley was last seen in the company of friends at Lake Overholser on April 13, 1986. At 2:00 p.m., she left her purse and cigarettes with her friends telling them she was going to take a motorcycle ride around the lake with a man she'd just met. She never returned from the supposed ride and this is her last confirmed contact.
The male companion in question has never been identified but he was described as a white man in his twenties, 5'10 to 6'0 and 180 to 200 pounds, with brown hair and possibly a brown mustache. His clothing comprised of jeans, a t-shirt and sunglasses. The motorcycle was a blue 650 cc or 750 cc Kawasaki model, possibly with out of state license plates.
The weeks leading up to Tinsley's disappearance had been marked with several life problems. Tinsley had three other people living in her one-bedroom apartment in the 1200 block of north Kennedy in Edmond, Oklahoma. Tinsley worked as a deliverer for the Oklahoman newspaper but since all her roommates were unemployed and none of them paid rent, she'd decided to evict them.
Police had also discovered marijuana cultivation in her closet. Although she denied possession of it, her fiance who served with the military in another state had sent her letters regularly asking her to send him drugs.
Circumstances of her life and disappearance have lead to suspicion of foul play. It has been theorized that her disappearance is drug-related and she may have known the man with the motorcycle.
