Lottery officials say a 52-year-old mechanic from northwest Missouri holds one of the two tickets matching all six numbers in the record $588-million Powerball jackpot.
A Missouri Lottery news release says Mark S. Hill bought the winning ticket for himself and his wife, Cindy, at a Trex Mart gas station in Dearborn.
The Hill family has four children.
The announcement was made Friday morning at a local high school in the small town, home to 500 people, 65 kilometres south of Kansas City.
The person who bought the other winning ticket at an Arizona food store still hasn't come forward.
Trex Mart's store manager Chris Naurez said business had been "crazy" for Powerball tickets lately and that the store sold about $27,000 worth of tickets leading up to the big draw.
"This really puts Dearborn on the map," he said.
Trex Mart general manager Kenny Gilbert suggested his staff would be sharing in the $50,000 bounty that the store will be awarded for selling one of the winning tickets.
"The response from the owner was, 'I guess we'll be able to give out Christmas bonuses,"' Gilbert said. "That's nice, especially at this time of year."
The $588-million jackpot is the second-largest in U.S. history, and the largest for Powerball.
Tickets sold at a rate of 130,000 a minute — about six times the volume from a week ago. That pushed the jackpot even higher, said Chuck Strutt, executive director of the Multi-State Lottery Association. It rolled over 16 consecutive times without a winner.
The lucky ticket-holders could split a cash payout of $384.7 million before taxes, or about $192 million each.
In a Mega Millions draw in March, three ticket buyers shared a $656-million jackpot, the largest lottery payout of all time.
