LEE COUNTY, Fla.- A mysterious voice on the other end of the phone is preying on people and asking for money. The caller is claiming to be a lieutenant with the Lee County Sheriff's Office telling you, you missed "jury duty" and now you owe a fine.

"My name is Lt. Martin with the Lee County Sheriff's Office."

It all began with that voicemail.

"Please give me a call back, thank you."

A woman who asked wink news to keep her identity hidden says she and her family were preyed upon, by an "imposter" posing as a sheriff's deputy. The caller, Lt. Martin, said the woman missed jury duty and had to pay a fine or be arrested.

"She said she didn't have the money and she would have to pawn her vehicle, he told her where to go and then go to Walmart and get a green dot card."

The "fake" deputy even ordered the woman to stay on the phone with him as she drove to pawn her car, but, instinct finally kicked in, and she figured out it was probably a scam.

"When she wouldn't give him the money, he became irate, made a verbal threat that he would kidnap her, rape her and kill her boyfriend."

The sheriffs office says there is no one at the department named Lt. John Martin and his badge number is bogus.

"People should be aware, the sheriffs office is never going to call someone demanding money, a green dot card, and if we are going to arrest you, you probably wont know until we get there," said fraud specialist with LCSO Bet Schell.

The sheriff's office is still investigating. WINK News wants to remind you to simply hang up if you receive a jury call asking you for money.
