Thomas County sheriff's investigators say problems between the two groups had been building for weeks.
Investigators say Wednesday’s incident spilled over from a roadway confrontation to a parking lot near the county high school, and that's when parents got involved.
"We did have one of the parents that got stabbed last night. He has been released from the hospital. He's going to be OK. We were concerned at first; he was stabbed in the chest. We had about four or five that had to go to the hospital last night,” says investigator Pascal Autry from the Thomas County Sheriff’s Office.
Investigators say Joshua Thompson, Jonathan Cade and Finley Gibson are all facing felony charges in connection with the incident.
Thursday night, investigators say the injured parent, Gerald Thompson is also facing charges for reckless conduct.
