Firefighters and paramedics were called to the scene about a possible drowning in the 500 block of Emerald Parkway in Buford around 7 p.m., fire department spokesman Lt. Colin S. Rhoden said.
The family was performing CPR on Shea Mitchell when rescue crews arrived, he said.
Crews took over and continued advanced treatment as the teen was taken to Northside Hospital Forsyth, where he was pronounced dead.
The cause of death will be determined by the medical examiner, Rhoden said.
