The winner of last week's $400 million Powerball jackpot came forward to cash in his ticket Monday, but we're not going to know who it is, because he told lottery officials he wants to remain anonymous, and under South Carolina law he's allowed to.

South Carolina is one of just six Powerball states that allow winners to keep their identities private, along with Delaware, Kansas, Maryland, North Dakota and Ohio. The reasoning of not allowing winners to be anonymous is so that it's transparent to the public that no scams are going on and that winnings are actually being awarded

The lottery released few details about the married winner, who lives in Columbia, saying he bought the winning ticket on the day of the drawing last Wednesday in what was only his second time ever playing the lottery. He checked his ticket at home the next day and realized he was the winner, but the only one around to tell at the time was his dog. He was the lone winner of the $400 million jackpot, the fourth largest in Powerball history.
