WEST ALLIS, Wis. (CBS 58) -- A new scam warning -- there are dozens of people pretending to be Powerball winner Manuel Franco.

Franco came forward last month to claim the $768 million jackpot.

His attorney Andrew Stoltmann says imposters are promising people large sums of money, but it's too good to be true.

"The scam is the imposters will say to individuals 'send me money so I can wire you $50,000, $100,000, or $200,000.' I would encourage anybody who receives one of these solicitations to simply turn it down and report that person to the FBI," said Stoltmann.
