Marcelina Flores Contreras, listed as Marcelina Flores Contreras in reports, was 76 when she vanished from Yakima, Washington on June 25, 1986. She was described as five feet tall, about 130 pounds, with graying hair and brown eyes. The day she disappeared showed no immediate signs of disturbance; there are no confirmed witnesses to her leaving or any clear indication of where she intended to go.

The Yakima Police Department kept her file open but investigators found very few leads. One unverified tip suggested she may have been contacted during a California Highway Patrol traffic stop after she was last seen, but that sighting could not be confirmed. Beyond that, the trail went cold and no definitive evidence has been reported explaining her disappearance.

If anyone in Yakima or along possible travel routes remembers seeing Marcelina around late June 1986 or has information that could help clarify her movements after June 25, please come forward. Who remembers her or has information about that day?
