IN BRIEF: Rockdale County High School was put under a lockdown at the end of the school day due to the possible presence of criminal suspect in the area, according to a message by school officials to parents.

A "preventative lockdown" was put in place for about 20 minutes after law enforcement advised school officials of a possible crime suspect nearby, said RCHS Principal Mary Ann Suddeth in a recorded message.

Law enforcement were reportedly looking for a possible suspect in an incident at the nearby Brandon Glen Apartments on Sigman Road. Around 1 p.m., a male resident who was bleeding severely knocked on his neighbor's doorways asking to call 911. The victim was taken to Rockdale Medical Center and transported to Atlanta Medical Center.

However, investigators are still sorting out the details of the scene and determining if there was a crime or a self-inflicted wound.

After the call to 911 about the bleeding victim, a possible person of interest was pulled over in a traffic stop on the road between RCHS and CJ Hicks Elementary, just before the end of the school day, but was released after they were determined not to be of interest.

The school was cleared by law enforcement for return to normal operations and the lockdown was lifted. The lockdown did cause a delay in return for students from Rockdale Career Academy.
