2 men shot at Main Event in Cobb County, police confirm

COBB COUNTY, Ga. - Cobb County police are working to find out who shot two men inside the Main Event entertainment center on Sunday evening.

What we know:

The department confirmed two men had been shot inside the business located at 3101 Cobb Parkway, near Cumberland Mall, at around 9 p.m.

FOX 5 Atlanta reviewed videos of the aftermath posted online. One video appears to show an argument right before the gunfire. Another appears to show a man on the ground being tended to by first responders.

Warning: These videos are graphic in nature and may be sensitive to some viewers.

Investigators say they believe there is one suspected shooter, who left the area before officers got to the scene.

Detectives say this is an ongoing investigation.

Cobb County police are investigating a shooting at the Main Event on Cobb Parkway SE.

What they're saying:

Dedra Carter, whose son was injured in the shooting, said it started when he asked an employee for water.

"I just saw her slap him as hard as she could, and it sounded off," she said. "Then some random guy came up, we don't know where he came from, but he came up and was like, 'Yeah, what's going on?'"

"The next thing I know, I see this guy come charging in. He's charging at my son now, and he takes the gun, and he just started shooting," she continued.

Carter said her grandson, who was also there, was traumatized by the experience.

"I just remember the last words of my grandson saying, ‘This is the worst birthday ever,' and he didn't even get to cut his cake," she said. "If it was traumatic for me, I can only imagine what it is for a five-year-old."

FOX 5 Atlanta spoke to another witness related to one of the men injured in the shooting.

"He obviously goes there. He knew a lot of the staff. Everybody just kind of seemed in cohoots," she said, referring to the shooter. "It makes you want to talk to the younger kids and let them know that, 'Hey, you're throwing your life away for a cup of water, something as simple as a cup of water, and it didn't have to escalate this far."

What we don't know:

The victims and suspected gunman have not been identified by name.

FOX 5 has reached out to Main Event to learn if any additional security measures will be added in the future and is still waiting for a response.
