Gregory Muckle, 66, was fatally shot in his Atlanta home during the early morning of June 26, 2016. Police responded to a Hamilton E. Holmes Drive residence in northwest Atlanta at about 2:30 a.m. and found Muckle suffering from gunshot injuries after an argument among the home’s residents reportedly escalated to gunfire.

Muckle lived in the house with two other people, a man and a woman. Both roommates were detained for questioning at the scene while investigators tried to determine which of the two fired the fatal shot.

Did anyone in the neighborhood know Gregory or have information about who else was at that house that night?
