LAKE MARY, Fla. -

Women are on alert after a bold rash of crimes that targeted them while they were at the gym.

The latest strike came at the YMCA on Longwood-Lake Mary Road in Lake Mary, when deputies said thieves smashed into nearly half a dozen cars to steal purses left in plain view.

Each of the women left their purses in the front seat, but it was not just women who were victims, one man left his wallet in the car, said a Seminole County Sheriff's report.

Morgan Stoun said she left her gym spin class Tuesday night and came out to find shattered glass and hundreds of dollars of damage to her car, all because her purse was in plain view of thieves.

Normally, Stoun hides it under a sweatshirt, but the one time she forgot became her first hard lesson as a victim.

"If they don't think it's in there, they're not going to try," said Stoun, who said it happened so fast, no one saw or heard a thing. "I think it's an easy place because they know people are going to be in there for a while. It's dark here, there are no cameras. I think it could happen anywhere."

It does happen at gyms often. Even a Longwood YMCA has had to warn its members before, with a sign positioned in the parking lot warning members to lock doors and hide purses.

"They post signs saying that it has happened," said Stoun, who now locks her purse in her trunk before going to the gym. "So, I know it's a thing, but I was hoping it wouldn't happen to me."
