Nobody has come forward with the winning $202 million Powerball ticket that was purchased at a convenience store in a suburb of Des Moines, Iowa.

It's the second giant Powerball winner sold in Iowa this year. Iowa lottery officials encourage people to talk with an attorney or financial planner before stepping forward.

The winning ticket matches all six numbers drawn last night.

Lottery officials say the winning ticket was bought at the Casey's General Store in Bondurant, where about $200 in tickets are sold a day. A company supervisor says there have been "a lot of phone calls and people scampering in to check their tickets."
