>> On WSBTV.com: 10 kids shot with pellet or BB gun on elementary school playground
Sources told WSB-TV's Michael Seiden on Tuesday that the teen is charged with nine counts of aggravated assault, one for each injured student. It's unclear whether he has been taken into custody yet.
A special meeting was held Tuesday night to address concerns about what happened and how the school reacted.
"I still wasn't informed," one parent told WSB-TV's Matt Johnson.
When Johnson asked Dr. Stephen Green about communication that parents asked for during the crisis, he said it is being reviewed.

"Maybe we can work to get something out as quickly as possible without sharing too many details for fear of being inaccurate," Green said.
The district is considering the construction of a fence around the playground to better secure it, but some parents say it's hard for their kids to return without an arrest in the case.
