On the morning of November 29, 2014, a gathering at a house on Richmond Avenue in southeast Atlanta ended in a mass shooting. Marcus Gay, 43, was among three people killed when assailants entered the home and opened fire; 19-year-old Joshua N. Barkley and 51-year-old Ricky Whitlock also died. Two other people — a man and a woman — were wounded but survived.

Investigators judged the attack was likely not random and believe the victims and perpetrators were probably known to each other. The Atlanta Police Department later released composite sketches of persons of interest, but no arrests or publicly named suspects have resulted. The case remains an open, unsolved homicide and a cold case.

Did anyone in the community have contact with Marcus Gay or the other victims on or before November 29, 2014, who might help investigators?
