SEMINOLE COUNTY, Fla. -

The owners of a popular outdoors facility, Wekiva Island, are offering a $10,000 reward for information that will help catch a possible arsonist who attempted to burn down their classroom and offices Monday morning.

Several patches of charred wood around the deck, under doors and on windows never grew to large fires, but it's the intention behind them that worries Mary Sue Weinaug.

"We're scared. We're afraid that someone's going to come back down and burn something else," Weinaug said.

Weinaug thinks whoever lit these fires tried about a dozen times or more to burn down the building at Wekiva Island, and it's not the first time they've been hit by a mysterious fire.

Three months ago, fire destroyed the bar in the middle of the night. Back then, fire investigators said it was an electrical fire, said Weinaug, but now she's not convinced it was an accident.

After suffering a second fire that is now being investigated as arson, the owners fear there's someone out to get them. They want the first fire's investigation reopened.

"My husband has asked them to reopen it," Weinaug said. "This is our life. We love the environment. We love the river, and somebody's trying to put us out of business."

After getting hit with roughly $20,000 in damage from fire, water and smoke, they're taking precautions. They've asked the sheriff's office to step up patrols and they've hired 24-hour security hoping to prevent another fire.
