On the morning of December 26, 1991, 23-year-old Bernice Charlotte Gray dropped her toddler at a day-care in St. Clair Shores, Michigan and never returned. She was scheduled to begin an 8:00 a.m. shift at a medical records office but did not show up; a resident nearby later reported hearing a sound like a firecracker around the time she vanished.

Bernice’s blue Pontiac 6000 was found four days later on Detroit’s east side with the car unlocked, keys on the floor, the driver’s window partially down, bloodstains later matched to Bernice, and two shell casings. A blood spatter expert concluded the pattern was consistent with a gunshot to the head in the driver’s seat and the body then being moved to the passenger side. Her purse was found the evening of her disappearance near an interstate in Detroit, but her body has never been recovered.

What can readers who knew Bernice or saw her car or movements that morning add to the timeline?
