And the $400 million Powerball winner is...

We still don't know. But, lottery officials do.

The winner of last week's $400 million Powerball® jackpot came forward Monday with the winning ticket, but the Columbia area resident wants to remain anonymous.

He told lottery officials that this is only the second time he's played the lottery. He stopped at the Murphy Express in Lexington last week because his wife told him to pick up hot dog buns. While he was there, he bought $20 worth of tickets. He also learned the convenience store doesn't sell hot dog buns.

He was home alone on Thursday when he checked his Powerball® ticket and learned he'd won, lottery officials said.

The Murphy Express that sold the winning ticket will receive a $50,000 bonus now that the prize has been claimed.

South Carolina gets $15 million in tax revenue, and the jackpot run will allow the lottery to transfer up to an additional $2 million in support of education, officials said.
