Good morning. I'm Renee Montagne. The mystery is over. Yesterday, Gloria MacKenzie of Florida showed up at the lottery office, revealing herself as the winner of last month's record Powerball jackpot.

MacKenzie said she bought her ticket at a supermarket, where another lottery player let her cut in line. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
