RED BUD, Illinois (CBS, AP) - The Illinois Lottery says the final winner of the record Mega Million jackpot has come forward.

Lottery officials said Monday that the winner will be revealed Wednesday. The single winner will be presented with a check for $218.6 million in the southern Illinois farming community of Red Bud. The winning ticket was bought at town's MotoMart convenience store along Main Street.

The March 30 drawing had three winning tickets for a record $656 million jackpot. Two winners already anonymously claimed their prizes in Maryland and Kansas. Illinois' winner used a quick pick -- an automatically generated set of digits -- to select the winning numbers.

The jackpot was the biggest in Mega Millions history. Kansas' winner, from Ottawa in Franklin County, claimed the prize in Topeka and chose to remain anonymous.
