AKRON, Ohio -- A fun trip to watch fireworks ended with violence for several spectators, and police said the teen who assaulted at least four people are still at large.

Akron police said the victims believe they were punched, kicked and stomped by a gang for no reason.

Marty Marshall and his family had just left Firestone Park after watching fireworks on June 27 and they went to a friend's house on Girard Street.

That's when, according to Marshall, 30 to 50 kids between the ages of 9 and 18 turned violent out of the blue.

Marshall tried to help a friend who got hit in the back of the head.

"The next thing, you know, I had 15, 10 kids around on me kicking me in the head, hitting me in the back of the head," said Marshall.

Rachel Hospon, 15, pulled one of the attackers off her father, then she too was knocked to the ground and got a bloody lip.

"I'm scared to sleep. I'm scared to talk to anybody, be close to anybody because it's just that fear," Hospon said.

Stunned by what she was witnessing, Yvonne Marshall tossed her 14-year-old son into some bushes to protect him.

"We home school our children because of the violence that was going on in schools to keep them safe and now this," she said.

Marty Marshall said he's still dealing with problems from the attack, including a concussion, migraine headaches and gaps in his memory.

No one has been arrested. Akron police said with so many suspects, they really need witnesses to come forward.
