Terry Peters, of Two Rivers, Wisconsin, became a millionaire Tuesday.
Peters validated the sole winning ticket from Saturday's $14.4 million Megabucks drawing at state lottery offices. Earlier on Monday, Peters had stopped by the store where he purchased the ticket to check if he was a winner.
He chose to take the lump sum cash payment of $7.6 million. He will receive about $5.4 million after taxes.
Peters will take part in a news conference at 10:30 a.m. Thursday at the GV Unimart in Mishicot, where he bought the ticket.
The winning numbers — 3, 7, 12, 21, 27, 30 — were drawn on Saturday, July 14.
"This was the only jackpot ticket sold for Megabucks," said Jennifer Lach, state lottery communications intern.
Winners have 180 days from the day of the drawing to claim their prize, Lach said. They have 60 days from the day they validate their winning jackpot ticket to determine whether they want to take a cash payment or annuity, she said.
The jackpot was the fifth largest in Megabucks history. The last Megabucks jackpot winner was Patricia Stage, of Bailey's Harbor, who won $15.4 million on Oct. 16, 2006, Lach said.
The odds of winning the jackpot, a six-out-of-six number match, are one in 6,991,908, according to the Wisconsin Lottery Web site.
