PIERRE, S.D. — The mystery Powerball winner will soon be identified.
The South Dakota Lottery plans a ceremony Friday afternoon in Pierre to introduce the winner of last week's $232.1 million jackpot.
The winning ticket from the May 27 drawing was purchased in the town of Winner, which has two Powerball lottery outlets.
It's the ninth-largest Powerball jackpot ever won and the biggest ever paid out in South Dakota.
