On the freezing night of January 28, 2012, 19-year-old John Johnson and his 20-year-old girlfriend Tailar Davis were found shot to death inside an idling blue Ford Taurus on the 4000 block of Richton Street on Detroit’s west side. Davis was in the driver’s seat and Johnson in the passenger seat; both had sustained fatal gunshot wounds. Emergency personnel pronounced them dead at the scene around midnight.

Investigators described the killings as execution-style and struggled to establish a motive. Crime Stoppers of Michigan publicized the case and offered a reward—initially up to $2,500 and later increased—seeking information that could lead to an arrest.

Did anyone in the neighborhood recall seeing the blue Taurus or suspicious activity on Richton Street that night?
