LOUISVILLE, Ky. (WHAS11) – A phone call...

“I came this close to being scammed of $4,000 today,” Paul Nadeau said.

That almost led to a $4,000 loss for Paul Nadeau of Louisville. Fortunately, his quick-thinking granddaughter didn't let that happen.

“I have to tell you something, Peter. My name is Stephanie and you've called and tried to take advantage of my 83-year-old grandfather.”

Stephanie Marshall recorded phone calls with an alleged scammer who was posing as Paul's friend, Peter, from church.

“I figured he's a friend, he needs some help and I was ready to give the money up,” Paul said.

The person claiming to be Peter told Paul he had been in an accident and in jail, now he needed the $4,000 for bail money.

Paul took notes while his alleged friend gave him strict instructions to get $4,000 in Target gift cards. Paul was about to head out the door but Stephanie stopped him. When Paul didn't call the person back, he called three times. Each time Stephanie answered and recorded the call. During the third call, Stephanie was fed up and told the alleged scammer she knew what he was doing and he became angered.

in the end, what could have been a real tragedy so close to the holidays, turned into a triumph and a warning for others.

“It's just really, really sad to me. It's wrong. It's just wrong,” Stephanie said.

Stephanie did contact police. They tell her that because no money was actually taken, the person behind the scam can't be charged.
