24-year-old claims $768 million Powerball jackpot, the 3rd-largest prize in U.S. lottery history

MADISON, Wis. (AP) - A 24-year-old suburban Milwaukee man says he screamed for about 5 or 10 minutes after realizing he won a $763 million Powerball jackpot -- the third largest in U.S. lottery history.

Manuel Franco, of West Allis, came forward at a news conference Tuesday in Madison, where Wisconsin's lottery is headquartered. Franco said his heart started racing when he realized one of the 10 individual tickets he bought a Powerball drawing last month was a winner.

Franco says he quit his job a couple days later but declined to say where he worked.

Franco says he plans to be wise about spending his new wealth and wants "to help out the world."

"I want to thank those closest to me for all the support they have given me over the years," said Franco. "To win feels something like a dream and I feel like at any moment I might wake up. I just can't believe an ordinary guy like me would ever be in this position. As a winner now, I don't plan on playing any more. But, I will say that the two-dollar ticket you buy is worth the chance to change your life forever. It certainly has changed my life and I look forward to the future."

He says he chose the cash option lump sum of $477 million.
