ZEPHYRHILLS, Fla. -- There is a multi-millionaire walking around in Central Florida thanks to Saturday's Powerball drawing.

The winning jackpot ticket was purchased at a grocery store in a town just outside Tampa but no one in the town seems to know who has that lucky ticket worth almost $600-million.

The town's mayor said if someone does know who it is they are not saying anything.

"That is the best kept secret in town. You can't keep a secret in this town and I know that for sure. The rumor mill's flying, but somebody knows, but they're not saying," said Daniel Burgess.

Saturday's record jackpot marks the largest in Powerball history.

It has a cash value of nearly $400 million.
