Chances are you made a return this holiday season. If it was in Marion County, you might have unknowingly been helping one Walmart worker line her pocketbooks.

Yezenia Degross, 19, worked in Customer Service at the Walmart on State Road 200 in Marion County up until her arrest this week. She told investigators how her scheme worked.

According to the Marion County Sheriff’s Office report, she said beginning in late November she was making returns for customers and keeping their receipts.

After customers were gone, she’d pull out those receipts and ring up some additional returns, keeping the cash herself.

But it turns out the cameras were watching, and deputies say she pocketed more than $5,500.

“It happens everyday in Ocala, in Orlando everywhere, people just trying to take advantage of the system," customer Frank Kennedy said.

“We shop at Walmart and if that goes on you are going to have prices increase more. It's not good for the other employees it’s a bad mark on them," customer Jane Hinton said.

DeGross told investigators she knew what she was doing was stealing. She was charged with grand theft.

She is free on $2,000 bond. DeGross offered no explanation when we went to her Marion Oaks home Friday to speak to her.
