A Volusia County day care owner is sick of thieves targeting her business, so she's fighting back.

Someone has broken into the Montessori Magic Pre-School in Port Orange five times in less than a year.

And while two teenagers were arrested, new cameras recently recorded a new adult burglar.

The owner, Jenylyn Fisher, told Channel 9 she's at her wits end dealing with the burglars, who she said have broken into just about every window before ransacking her day care.

New security surveillance has taken $6,000 out of Fisher's budget -- money which she had planned to use for the kids and a new playground.

"They have forced me to put security in all the way around," she said.

After the break-ins started, Fisher started a file. In the file are police reports and even apology letters from two of the teens who were caught several months ago.

One of the apologies reads, "Dear Jenylyn, I apologize for coming into your place of business and taking the money that you work for. I'm sorry for this and putting you through this."

But Fisher said the apologies don't mean a thing to her, especially since she's dealing with a new criminal who broke in on Sunday.

The video shows the burglar knew exactly where to look for the cash, but he didn't think about covering his face before going inside, which Fisher hopes is enough to find him.

"I'm camp out fed up," said Fisher. "Like, I just want to sit here all day and protect everything I have."

Police said the day care is not in a high-crime area, and they've stepped up patrols since the burglaries started.

The latest burglar, however, is still on the loose.

Anyone with information is asked to contact authorities.
