MADISON, Wis. (WHBL) - One Powerball ticket sold in Wisconsin was good for a million dollar prize. It was the jackpot of 588 million dollars, but Dennis and Mary Retterath came to the Wisconsin Lottery headquarters in Madison yesterday to cash in. After taxes, the West Allis couple received 672 thousand, 500 dollars. Retterath says she bought the Quick Pick ticket at a Speedway in West Allis. The ticket matched all five regular winning numbers, but missed on the Powerball. Retterath and her husband will be at a news conference Monday at City Hall in West Allis. A Missouri couple has claimed half of the big prize. The other half goes to whoever has the other winning ticket. It was sold in the Phoenix area.
