Fort Myers police release description of ZombiCon shooting suspect.

FORT MYERS — Police released a vague description of a suspect who shot into a crowd during a zombie festival over the weekend, causing people dressed in ghoulish costumes to scream and sprint down the streets.

One person was killed, and five were wounded.

Police said the shooter is a white or possibly Hispanic man in his late teens or early 20s. He was dressed in a black T-shirt and wore a flat-billed black and red ball cap. He was firing a black semi-automatic handgun.

Authorities have not given a motive or made any arrests. They said the investigation was challenging because thousands of people at the event were in costume, wearing masks and smeared with fake blood. Some even carried fake weapons that looked real.

“Everybody was in bloody, gory makeup,” said Jill Stancel, who was selling water Saturday night from her mother’s barber shop when the shots rang out just outside her business’ door.

The small Gulf Coast city is known more for its retirement communities than downtown revelry. But for the past eight years, it has hosted ZombiCon, which touts itself as “the largest gathering of zombies and those who love them in the state of Florida.”

The event draws about 20,000 people to downtown, where George Romero filmed the opening scene of “Day of The Dead,” a seminal zombie movie.

Police also released a video taken by someone at the festival that shows hundreds of people in costume milling around. Four loud pops are heard in the video, and then people start to run.

The shooting happened around 11:45 p.m., just 15 minutes before the event officially ended. Officials are hopeful that through social media, tips and videos, they will find the shooter.

“Please keep the tips coming as they are invaluable,” the Fort Myers Police Department said.

Retired Tampa Police Chief Jane Castor said she thinks people will talk about the shooter, or the shooter will have revealed details to someone, or on social media.
