Police have said 21-year-old store clerk Martez McKibben died on the floor of the Moreland Package Store after being shot during a robbery Dec. 4.
The surveillance video from the store was released Thursday and broadcast on WGNX, the Atlanta CBS station. It shows two paramedics and a firefighter walking into the store and looking behind the counter, where McKibben was lying.
"They just looked at him, didn't even reach down and feel for a pulse. When police asked us to leave the building he was still breathing," store owner Shun Yu told the television station.
The station said the department released the following statement Thursday: "Due to the release of video, by Channel 46 News, showing firefighters responding to the December 4, 2009 shooting at the Moreland Avenue Package store, the Atlanta Fire Rescue Department has launched an internal investigation into the incident."
The department said it would have no further comment until it has had a chance to review the video and talk to the emergency workers involved.
Police said Terrone Anthony and Aaron Jackson, both 19, walked into the store just before 10 p.m. Dec. 4. Anthony pulled a gun and shot McKibben in the stomach and buttocks, police said.
When Anthony tried to flee, Yu, the store owner came from the back of the store with his own gun and shot Anthony in the arm and leg. Anthony was arrested a short time later about a block from the store. Jackson was arrested Friday.
Both suspects have been denied bond. Anthony, who was still in Grady Memorial Hospital, is charged with murder, armed robbery and theft. Jackson is being held in the Fulton County jail and faces murder and armed robbery charges.
McKibben's mother told the Atlanta Journal-Constitution that rescuers might have been able to save her son.
"A paramedic is supposed to come in and see if it's anything they can do to help a person, and clearly the video shows they did not do that," she told the newspaper. "They never laid a hand on my child, and I'm very angry."
