Historic Powerball winner Jack Whittaker has died at 73. Whittaker won the $315 million Powerball jackpot on Christmas night in 2002, which at the time was the largest jackpot ever won by a single ticket in American lottery history. Before he won the lottery, Whittaker owned three construction companies. Following the win, Whittaker was robbed twice, had two family members found dead and had various legal trouble. He also donated millions through the Jack Whittaker Foundation.
