“They shot my baby in the head,” sobbed a grieving mother as Fayette police investigated a triple shooting inside an upscale Fairburn subdivision over the weekend.

The woman’s son was one of hundreds of teens who attended a private house party on Saturday night in the 200 block of Moss Creek Court. Witnesses say the party got out of control when a fight broke out inside the house between invited and uninvited guests.

“A lot of the people in attendance were not invited. It’s our understanding that they may have gotten word of the party through MySpace and text messages,” said Fayette County Sheriff’s Office Lt. Belinda McCastle.

The party was over by the time Fayette County Sheriffs were called to the scene by residents who complained about the cars parked on both sides of the street blocking them in.

As police investigated the complaints, gunshots rang out near the party house. One teen was killed from a gunshot wound to the head. Two other males were hit by gunfire and transported to a local hospital. Fayette County Sheriff’s office said the two injured men had non-life-threatening injuries and were between the ages of 18 and 21.

The gunman is still at large.
