The winning Arizona ticket was purchased at a Four Sons Food Store in Fountain Hills, Ariz., and was part of a $10 Quick Pick ticket, officials announced Thursday afternoon. Arizona lottery officials said they had no information on that state's winner or winners as of Thursday.
"It's been insane," Trex Mart employee Kelly Blount said. "I would never have thought we would have sold the winning ticket. It's wonderful."
Store manager Chris Naurez told The Associated Press that business had been "crazy" for Powerball tickets lately and that the store had sold about $27,000 worth of tickets in the past few days. Naurez says this lottery win could make Dearborn, a town of 498, famous.
"This really puts Dearborn on the map," he said.
