COLFAX, Iowa (AP) — Iowa Lottery officials say someone who bought a Mega Millions ticket at a central Iowa convenience store won a $1 million prize. The ticket was purchased at Kum & Go in Colfax. It matched the first five numbers in Tuesday night’s drawing for the $55 million jackpot but missed the Mega Ball number. A ticket bought in California also is worth $1 million. No ticket bought matched all six numbers, so the jackpot is expected to climb to $68 million for Friday’s drawing. Prizes of $1 million or more in Iowa must be claimed at Iowa Lottery headquarters in Clive.
