Remember that $750 million Powerball jackpot back on October 27th? It was the third-largest Powerball jackpot in history. And there were two winning tickets . . . one in New York that hasn't been claimed, and one in Iowa that went missing. But a 51-year-old grandmother named Lerynne West just found it. She left it on the floor of her sister's truck, and now gets $343.9 million. She got emotional at the press conference, talking about a grandchild that passed away.
