A Crossville woman reports she has lost about $20,000 in a prize winning scam. The woman told the Cumberland County Sheriff’s Department that she had been receiving phone calls from a man who said his name was John Walker. The man told the victim that he worked for “Winner’s International” and said that she had won $2.5 million but before she could claim the prize she had to send him money for the IRS fines. The woman gave the man her bank information and several credit card numbers. The woman’s bank account did receive checks, including one for $5,000, but they were shortly taken back out of her account. She believes she gave the man approximately $20,000 between her bank account and credit cards. Authorities remind everyone never to give out your personal information to people you do not know.
