The winning ticket from the $267 million Mega Millions drawing Tuesday night was sold in the northwest Ohio town of Lyons, an Ohio Lottery spokeswoman said.
The ticket was purchased at Lyons Main Stop, lottery spokeswoman Marie Kilbane told The Associated Press.
Store manager Linda Freeworth said she received the news from a radio station that called about 4:45 a.m. Wednesday. Radio and television reporters arrived soon after for interviews.
"I've never been a big time winner. People laugh because this is a small town and nothing ever happens here," she told The AP in a telephone interview.
Lyons is 26 miles west of Toledo, near the Ohio-Michigan line.
Lottery officials planned a news conference later Wednesday, Kilbane said.
Freeworth said she had not spoken with lottery officials and did not know who bought the winning ticket.
The winning numbers from Tuesday night's drawing were 2, 4, 35, 36 and 48. The Mega Ball number was 22.
In addition to the grand prize winner, 22 tickets matched all five numbers but not the Mega Ball: 4 from California, 2 from Georgia, 3 from Illinois, 2 from New Jersey, 7 from New York, 2 from Ohio, 1 from Texas, and 1 from Virginia. The winners will receive second prizes of $250,000 each.
The 4 California winners will receive $237,869 each because California prize amounts are calculated based on the amount of sales and the number of winners.
Another 134 tickets matched four numbers, plus the Mega Ball number — good for third prizes of $10,000 each ($8,109 in California).
