LANSING, Mich. (AP) — Lottery officials say the winner of last week’s $310.5 million Powerball game has come forward.

The Michigan Lottery says a Tuesday news conference is planned to identify the winner.

The Three Rivers West Shell station in the southwestern Michigan community of Three Rivers sold the only winning ticket for last Wednesday night’s drawing.

The jackpot can be paid over 30 years or the winner can choose a lump sum of about $197 million before taxes.

The gas station, 30 miles south of Kalamazoo, is just minutes from the Indiana border, so the winner might be from out of state. The numbers are 21, 39, 40, 55 and 59, and the Powerball is 17.
