It took three days for Napolean Elvord to realize that he had the winning Megabucks ticket from the January 14 drawing, bought at a Wisconsin Mobil station. Clerks at the Madison, WI store asked him if he was the one who bought the winning ticket. He said he wasn’t the winner…but as the days went by, no one claimed the prize.

Store manager, Corky Wunderlin, asked Elvord again. This time it occurred to Elvord. He had confused the drawing days that produced the Megabucks winner. Elvord checked and found the winning $1 ticket sitting on a table. He took it to the Wisconsin Lottery office for validation. He then received a lump-sum payment of $10.2 million — $6.87 million after taxes.

Elvord plans to go back to Texas and use the money for health insurance. He has needed regular kidney dialysis for the last five years.
