Conyers Police Lt. Jackie Dunn said there was up to 75 people at the Conyers home late Saturday. They say people paid $3 each to get in.
Neighbors called police complaining of the loud noise around 9 p.m. and officers left the area after they thought they broke up the party. But authorities say a fight broke out and shots were fired around midnight.
Authorities say an 18-year-old was shot and later died from his injuries. They say a 15-year-old and a 16-year-old were also injured in the gunfire.
Police say they are looking for the shooters.
