The fourth Quick Pick was the one that delivered home the winning combination, the officials said.
So when the numbers 28, 30, 39, 59, 70 and the Mega Ball, 10, were announced, Missler said he simply placed a call to share the news with his brother.
Then he met with his father the following morning for a cup of coffee, officials said.
The 7-Eleven will receive a $100,000 bonus commission for selling the winning ticket.
The lucky person who bought the winning $560 million Powerball ticket in New Hampshire is still a mystery.
Lottery officials confirmed that the ticket was sold at Reeds Ferry Market in Merrimack, some 25 miles south of Concord.
The store, officials said, will receive a $75,000 commission.
