DES MOINES, Iowa (AP) – Iowa Lottery officials say someone who bought a Powerball ticket at a Council Bluffs convenience store has won $1 million.  The lottery said in a news release Thursday that the ticket matched the first five numbers of 9, 10, 24, 52 and 56 but missed the Powerball number of 14.  The lottery says the ticket was purchased at D&S X-Press on North Broadway and that the buyer hasn’t come forward yet.   The lottery says it’s the fourth $1 million-winning ticket sold since the $2 Powerball began in January. One of prizes was claimed by a Council Bluffs woman.  No one matched all six numbers in Wednesday night’s drawing, so jackpot is expected to hit $164 million for Saturday’s drawing.
