Dorothy Williams, 23, disappeared from Philadelphia on January 13, 1987 after telling her family she was going to the store for some food. She left wearing a black and white speckled coat, a pink sweatshirt, dark blue pants and black flat shoes. Known also as Dee and Dot and sometimes using the surname Thornton, she was a Black woman with red or auburn hair, brown eyes, about five feet six inches and 130 pounds. She had a metal piece implanted in her right elbow from a prior broken arm.

The Philadelphia Police Department opened an investigation but the trail went cold quickly. It is not publicly known whether she was on foot or in a vehicle when she left, and there are no known witnesses to her disappearance. If anyone knew Dorothy, where she shopped, or saw her on January 13, 1987, please come forward with information.
