Carol Jane Edwards, 25, disappeared from her Shoreline, Washington, home after arriving from work on January 2, 1981. She had left TV Guide in downtown Seattle that afternoon, spoke by phone with her sister Sally Head before catching the King County Metro bus, and was believed to have arrived home around 5 p.m. that evening.

Inside the house investigators found a puzzling scene: keys and that day’s mail on a counter, a load of laundry started, her coat on the garage floor, the house dark with no lights on, and her purse missing. Her dog was found tied up outside, which family members say Carol would not have done. There were no obvious signs of forced entry or struggle. Her bank accounts were never used again and she made no further contact with friends or family.

The King County Sheriff’s Office has kept the case open. Detectives collected DNA evidence from the scene and have pursued leads and persons of interest over the years. Her then-boyfriend was interviewed, polygraphed, and provided DNA but has not been treated as a suspect; Gary Ridgway was investigated and ruled out. Does anyone have memories or information about Carol’s last known movements or the Shoreline neighborhood around January 1981?
