JEFFERSON COUNTY — The spectacle that is Red Rocks draws onlookers by day. But, as preparations are made for the concerts at night, is Red Rocks a different place?

"There was a hole completely through my lip and five stitches on the inside," Garth Jabob, 26, said.

Jacob went to Red Rocks on August 16 to see a band called Almost Dead.

"We were hanging out in the third row during set break. I was with my dad, we were celebrating his birthday. And, as I turned to look back at the crowd, I got punched right in the mouth," Jacob said.

He says it was completely unprovoked. For some reason, this man wearing a plaid shirt standing about 6-feet high punched him in the mouth causing permanent damage, according to Jacob.

"My hard pallet and then the bone in front of my teeth are both broken," Jacob said.

The Jefferson County Sheriff's Office released surveillance video of a man in a plaid shirt leaving Red Rocks with hopes of creating a lead.

"We're just hoping that somebody who may know the suspect or may have been at the concert also will recognize him and be able to tell us who he is," Jenny Fulton, Jefferson County Sheriff's Office, said.

Jacob still doesn't understand why he was hit.

"Honestly, I think it was just a senseless act of violence," Jacob said.

But, it is not the first. A lawsuit filed in Denver District Court says the Winter on the Rocks concert in January, a man named Joey Oertli was beaten and security with Argus Event Staffing did nothing to help him or protect him.

Brian Kitts is with Denver Arts and Venue, the department which oversees places like the Buell Theater, Ellie Caulkins Opera House, and Red Rocks Amphitheater.

"We'll have about 1.3 million people go through the venue each year. We've had two serious assaults and probably fewer than half a dozen fights in general," Kitts said.

He says the numbers prove that Red Rocks, overall, is pretty safe.

"If there is something serious, we do see a pattern, we'd like to figure out a way to help it," Kitts said. "That's just not the case here."

Denver Police and private security are the primary enforcement at Red Rocks. The Jefferson County Sheriff's Office gets involved when a felony has occurred. Fulton says her department does not see an ongoing problem at Red Rocks.

"Certainly, we encourage people to continue and enjoy Red Rocks and have no fear about incidents such as this," Fulton said.

Jacob says he's not soured on concerts because of his attack. He still wants people to enjoy the park and concert venue. He just also wants justice, too.

"It was not fun," Jacob said. "Not what you'd expect from a Red Rocks show."
