One person was killed and four others were wounded late Saturday in a shooting incident at a "ZombiCon" festival in Fort Myers, Florida. The suspect is still at large, according to media reports.

The incident reportedly took place at 11:45 p.m. Saturday. The four surviving victims have been taken to a hospital and are being treated for non-life threatening injuries, Lt. Victor Medico of the Fort Myers Police Department reportedly said.

"There was a lot of witnesses down here, there were a lot of people taking pictures, videos with their cellphone," Medico said. "Anything that could help with this investigation would be greatly appreciated."

The annual event, during which participants dress as zombies to raise money for charity, was expected to have drawn more than 20,000 people. In a statement, the organizers of the gathering said they were "deeply saddened" by the shooting incident that occurred "within the footprint" of the event.

"We take the safety of our patrons very seriously and take precautions in hiring security and police officers for our annual event," the organizers, Pushing DaiZies, Inc., said, in a statement posted on Facebook.
