One of the two winning Powerball tickets for an estimated $587.5 million jackpot was sold in the Kansas City area.

Missouri Lottery spokesman Gary Gonder says the winner has not yet come forward Thursday to claim the record prize, but there is no rush. The winner has 180 days to do so.

Gonder says he is traveling to the store that sold the winning ticket to help with an expected onslaught of media attention. Missouri Lottery officials plan to announce the identity of the retailer later Thursday.

The other winning Powerball ticket was sold in Arizona.

The Missouri Lottery says two $1 million winning Powerball tickets were also sold in the state — one in Joplin and the other in Kansas City.
