Cullman police are looking to identified those involved in an assault Saturday night at the Rock the South music festival that sent at least one man to the hospital.

Event organizers are offering a $10,000 reward in the case.

Cullman police directed AL.com to a statement on the department’s Facebook page.

“The Cullman Police Department is aware of the assault that took place at Rock the South last evening,” according to the statement. “A report is being filed and an investigation is underway.”

“We are relying on the public’s assistance in identifying those involved,” according to the statement.

Kaci Howard, in a Facebook post Sunday, identified her son as an assault victim at the Rock the South event.

“PLEASE help me find the cowards who did this to my son tonight at Rock the South. There were several grown men (30s-40s) who jumped on him and beat him unconscious while his girlfriend stood there screaming and crying for help,” Howard stated.

“They continued beating him while he was on the ground until security finally got to them and got Reid and Katie out of there and to an ambulance. He has a fractured nose, concussion, stitches, knots the size of softballs on the back of his head. He never even saw it coming. They jumped on him out of nowhere because one of them said he spilled a drink on him. Reid didn’t even have a drink in his hand. Anyone who’s ever met Reid knows his personality. He never meets a stranger, he can literally get along with anyone. He is a good kid and he did not deserve this. PLEASE share and help me find who’s responsible.

“One of them had long curly hair, red white and blue hat, about 6 ft. and a bigger guy wearing a white shirt. I don’t have much of a description of the rest of them but I know a lot of people saw so someone knows who these cowards are.”

Video of the fight was put on Facebook.

“Please let me or the Cullman Police know if you recognize any of these guys,” Howard wrote.

Laura Quick, wife of festival founder Shane Quick, confirmed to AL.com that there is a $10,000 reward, plus lifetime tickets to the event, being offered for information leading to the arrest and conviction of those responsible for the assault.

This year’s event included 16 acts during the three-night run, including headliners Chris Stapleton, Riley Green and Zach Bryan, with Dee Jay Silver spinning tunes between sets.

At the end of the event Saturday night, Shane Quick announced to the crowd that Rock the South had broken attendance records. “This is the largest Rock the South in history,” Shane Quick said. “People from 13 countries are here tonight. Every single state in the United States of America is here tonight.”
