NAPLES, Fla. - A woman caught a scammer before he took thousands from her. It all started like most scams do... while she was looking for work.

The job ad ran in a local newspaper. It was a part-time position as a nanny and it paid good money, but the job one woman was offered after she responded - had nothing to do with babysitting.

Dana Porcelli was looking for a way to make a little extra money, so she responded to an ad to work as a nanny.

"It was 800 dollars a week. You get your own car, it's only 12-6 and no weekends so I applied because, I mean, 800 dollars a week is a lot of money."

When Porcelli replied, she was told the position was full, but the person who posted the ad said Porcelli caught her interest and referred her to a family friend, so Porcelli sent him an email... but this new job sounded bad.

"I knew it was a scam. It had nothing to do with a nanny position at all. It was sending money out of the country."

A man who goes by Edwards Murray said he would pay Porcelli 10 percent of every payment she received from his clients. Then, she would have to send back the remaining balance to a warehouse manager.

"It just didn't seem right to me - a gut feeling it was wrong."

Her fear? The check she would receive would be fake, and the one she would send out would be real - costing her thousands.

We've shown you so many scams that work this way.

"I just felt really aggravated, upset - just angry inside. When I read the email I was so excited I got a response then I read it and I go, 'Oh my God, this is a scam.'"

That woman called WINK News because she wanted us to tell her story - afraid other people would people fall for similar scams and lose money, instead of make it.
