The winner of a $144 million Powerball jackpot has finally stepped forward, nearly three weeks after the lottery drawing, demonstrating one of the best ways for a lottery player to claim a big prize. The 82-year-old from Washington D.C. had his lawyer claim the prize on Monday on behalf of a corporation set up to keep his identity secret.  The man is a widower with 10 children and 47 grandchildren and great-grandchildren. He purchased the ticket at a local supermarket.  The winner of the massive prize is a life-long D.C. resident and has played the lottery since it came to the city.  He won the jackpot with one single ticket purchased for $1.00.  For more, click here.
