came home to a voice mail from a lieutenant at the sheriff's department, she took it seriously. >> there was a warrant out for my arrest. i had not attended jury duty and i needed to pay a fine. >> reporter: she was told to pay more than $300 through a cash card she could buy at a convenience store. >> once you give them that verification card, the money is gone. i felt really stupid. as someone who is educated. i thought i was immune to something like this. >> reporter: it's called the injury duty scam and states around the country are reporting victims. take a listen to this scam artist talking to an undercover deputy. >> normally we do not make these phone calls. we proceed to your address and place you in custody. >> how do i fix this? i've never been in trouble before. >> reporter: they aren't the only scam artists. i called one who claimed i owed back taxes. >> am i in trouble with the irs? >> yes, sir. we found the amount which you paid in 2011 and 12 that was not correct amount.
