A very lucky person — or persons? — won a share of the landmark $640 million Mega Millions jackpot through a “quick pick” at a Baltimore County convenience store, Maryland Lottery officials said Saturday.

The winning number was purchased at 7:15 p.m. Friday at the 7-Eleven at 8014 Liberty Rd. in Baltimore County, and the buyer allowed the computer to pick the numbers, Maryland Lottery spokeswoman Carole Everett said. .

The buyer has not yet come forward, Everett said.

The Associated Press reported that the 7-Eleven is located on main road, among fast-food restaurants and small businesses. It will receive a $100,000 bonus for selling a winning ticket, AP said. The manager declined comment to AP.

The winner is one of three nationwide who will split the $640 million. The other winning tickets were sold in Illinois and Kansas.

Everett said a record $11.8 million was spent on lottery tickets Friday in Maryland, beating the previous record of $5.8 million set for a single day in 2007.
