Shirley Gertrude Pullen, 70, vanished from the Windward Village Mobile Home Park in Niles, Michigan, after being last seen on December 31, 1986. She was last observed by her hairdresser at a Save Mart in South Bend, Indiana, that day and mentioned plans for a New Year’s Eve party before returning to her trailer. Shirley was insulin-dependent and may have been experiencing dementia; she is described as a white woman, 5 feet 5 inches tall, 125–150 pounds, with brown eyes and brown hair and sometimes wearing brown or blonde wigs.

Shirley was reported missing on January 12, 1987, after park staff and relatives discovered her trailer in an unusual state: a half-eaten sandwich, a cigarette burned to the filter, and the television left on. Her coat, luggage, vehicle, and other personal effects remained behind.

Shirley has not accessed her Social Security benefits or her insulin since she vanished, and her body has never been found. No arrests or charges have been reported. What remains unclear is Shirley’s final route or destination on December 31 and whether she left voluntarily or was harmed; foul play is strongly suspected. If anyone knew Shirley, saw her that New Year’s Eve, or has information about the men seen outside her trailer, please come forward.
