On October 21, 1974, police in Highland Park, Michigan, responded to an anonymous tip and found 28-year-old Shirley Sailor and her common-law husband, novelist Donald Goines, both dead of multiple gunshot wounds. Sailor was located in the kitchen with multiple shots to her chest and head; Goines was found in the living room with fatal gunshot wounds. The couple’s two young children were in the home at the time and were unharmed.

Investigators opened a homicide inquiry that produced no clear suspects or motives. Over the years theories tied the killings to Goines’s troubled life and to his gritty novels, including speculation about drug-related disputes or reprisals linked to portrayals of real-life figures, but no arrests or public identifications of suspects have been made. The case remains unsolved.

Did anyone who knew Shirley Sailor or the household in Highland Park in 1974 see or hear anything that might still help explain what happened?
