MADISON, Wis. -

Madison police are looking for a suspect involved in Saturday's shooting at East Towne Mall.

Officers were called to the mall at 2:50 p.m. for reports of shots fired. Investigators believe the shooting stemmed from a disturbance between several young men. One pulled out a handgun and fired at least one round.

Madison police spokesman Joel DeSpain said a 19-year-old was hit in the leg during the incident. He was taken to a hospital with a non-life-threatening wound.

Officers cleared the mall searching for a suspect, but as of Saturday evening, no suspect had been located, DeSpain said.

The mall reopened about three hours later.

Witnesses described the scene as chaotic, with shoppers running to get out of the mall.

"I saw people get trampled," said Bill Peters, who was shopping at the mall at the time of the incident. "I saw an elderly couple, people in wheel chairs and kids get knocked down by people panicking. I guess that just happens. People end up in panic mode and don't think, they just act."

"This is a very busy time of year," said Tammy Peters, who was also inside the mall during the shooting. "Santa is here with all the kids. It was not far from Santa and a lot of people got separated from their families."

Police asked anyone with information on the gunman to contact Madison Area Crime Stoppers at 266-6014.

East Towne Mall is an 840,000-square-foot shopping center at the intersection of East Washington Avenue, Zeier Road and Lien Road. It has more than 110 specialty retailers, according to the mall website.
