Jefferson County Sheriff's investigators are currently looking for a teenager who they believe fired the shots that injured several people at a carnival Saturday night.

Investigators now say six young people -- five teenagers and a baby -- were injured by gunfire Saturday night at a festival at Cathedral of the Cross A.O.H. Church of God off Center Point Parkway.

Deputies said four people were reported at the scene with gunshot wounds. Another two people were later discovered to have been driven to a hospital in a private car with minor gunshot wound injuries.

Four of the victims, including the one-year-old, were struck by single shots in the leg, one was struck in the elbow, and one grazed in the shoulder. The teenaged victims ranged in ages from 16 to 18.

A pregnant woman was also taken to the hospital for minor injuries she received when she was knocked to the ground by people fleeing gunfire. All the injuries were described as non-life threatening.

The incident happened about 9:30 p.m. Saturday. Five people were taken into custody at the scene.

Approximately 900 people were at the carnival at the time - 800 inside the event and 100 waiting in line to get in. Authorities said the incident could have been much worse.

Chief Deputy Randy Christian said the shooting apparently involved a group of teens at the carnival who began arguing and then fighting. During the fight, one of the teens pulled a gun and began firing as he ran.

"He is the only suspect who fired shots," Christian said. "He has been identified and a search for him is being conducted."

The festival organizers, in a statement, said the carnival would be closed today "in the best interest of all parties involved." The carnival was not affiliated with the church.

"So we have one idiot thug that ruined the night for about one thousand kids and their families," Christian said. "There is no excuse for it and the sad thing is he likely isn't even sorry about it. I'm sure the argument was something really important like what kind of tennis shoes someone was wearing. I really am shaking my head."
