ZEPHYRHILLS, Fla. - Some lucky person walked into a Publix supermarket in suburban Florida over the past few days and bought a ticket now worth an estimated $590.5 million - the highest Powerball jackpot in history.

On Sunday, he loaded groceries into his car after shopping at the Publix.

"This would be the sixth Florida Powerball winner and right now, it's the sole winner of the largest ever Powerball jackpot," Florida Lottery executive Cindy O'Connell told The Associated Press.
