Lottery officials revealed that Mark and Cindy Hill, of Dearborn, held one of two winning tickets for the nation's biggest Powerball jackpot.

"I think I was having a heart attack," Cindy Hill, a former office manager laid off in June 2010, told reporters Friday as she recalled matching the ticket she bought with the winning numbers.

Her husband, Mark, is a mechanic at the Hillshire Brands meat processing plant in St. Joseph. The couple adopted a daughter from China five years ago and are now considering a second adoption with their winnings, according to a statement from lottery officials.
