“It feels like a dream,” Franco, 24, said at a press conference Tuesday.
The winning ticket was sold on March 27 at a Speedway in New Berlin, about 15 miles west of Milwaukee.
“I walked into the Speedway and I purchased $10 worth of individual Powerball tickets,” Franco said. “I honestly felt so lucky that I did look up at the camera and I wanted to wink at it cause I just had that lucky feeling.”
The jackpot has a lump sum cash value of $477 million, according to the Powerball website.
State law does not allow the winner to stay anonymous, said Wisconsin Lottery Director Cindy Polzin.
Franco had 180 days to claim the ticket.
