DEARBORN, Mo. (AP) — Missouri Lottery officials on Thursday verified one of two tickets that matched all six numbers to split a record $588 million Powerball jackpot, but that ticket holder — and another in Arizona — remained a mystery, even as neighbors and co-workers lamented their losses and gossiped about who may have won.

The tickets were sold at a convenience store in suburban Phoenix and a gas station in Dearborn, Mo., just off Interstate 29, the highway linking Kansas City to the Canadian border.
