The Buchanan County Sheriff's Department said people are getting call claiming they have won a million dollar prize from Publisher's Clearing House.
The caller, according to Col. Bill Puett, then asks the "winner" to purchase a $500 cash card from Wal-Mart.
The sheriff's department said the scammers will call back several times to see if a person has purchased the card, even saying they will help senior citizens in order to get them their grand prize.
"We want to get this information out obviously so people know it's a scam," said Col. Bill Puett with the Buchanan County Sheriff's Department. "When you start using large names like Publisher's Clearing House and Wal-Mart, they try to add legitimacy to their scam."
The Buchanan County Sheriff's Department reminds people not to give their personal information over the phone.
