Chauncey Harold Jones, 46, was shot to death in his Temple Hills, Maryland, home in the early hours of Memorial Day 2007. Police were called to a residence in the 3600 block of 24th Avenue around 2 a.m., where they found that a heated argument had preceded a single, fatal gunshot.

A witness told officers that Jones and another man had been engaged in a dispute; the subject of that disagreement was not reported. Frederick Louis Gwyn, who lived at the same address, was arrested at the scene and charged with manslaughter in connection with Jones’s death.

Does anyone have information about what sparked the argument or knew either man at that address?
