Jevon Galloway, a 20-year-old Black man from Memphis, Tennessee, was found shot to death on a sidewalk in the Frayser area on December 28, 2014. Police said the killing grew out of an argument that turned lethal, and investigators reported that the dispute may have involved another person who was driving a gold Cadillac — a detail released early in the inquiry and repeatedly noted in accounts of the case.

The slaying was recorded as the city’s final homicide of 2014 and was investigated with canvassing and witness interviews as detectives tried to reconstruct who had been present and how the argument escalated.

Does anyone who knew Jevon or who was in the Frayser area that day have information about the gold Cadillac or the argument that preceded the shooting?
