AIKEN -- An Aiken police officer was killed and another officer was injured in a shootout following a traffic stop at an apartment complex, police said.

A suspect wounded in the shooting was taken to the Medical College of Georgia in Augusta for treatment, said Lisa Hintz, assistant director for Aiken Rescue. The suspect's name was not released. There was no word on the suspect's condition.

The shooting happened at an apartment complex around 8:30 p.m. Tuesday, Lt. David Turno said.

Master Public Safety Officer Scotty Richardson, 33, died from his wounds, Turno said in a statement Wednesday.

Officer Travis Griffin, 28, was treated and released after his bullet-proof vest took a gunshot in the chest.

Workers at the Aiken Rescue headquarters heard about a dozen shots, Hintz said.

Turno did not respond to a call Wednesday morning.

Two people were being questions, but Turno would not elaborate Tuesday night.

The State Law Enforcement Division was investigating, which is standard procedure in an officer-involved shooting.

Sheriff's deputies, North Augusta police and the Highway Patrol were responding to calls in Aiken.

"They've taken over for the city tonight so we can take care of our own people," Turno said.

Richardson had been with the department since 1999, and was married and had three young children, Turno said.

Griffin has been with the department since 2009.
