EDISON - The clock is ticking for a mystery lottery winner who has yet to claim his $1 million prize.

One winning lottery ticket was purchased at a 7-Eleven in Elmwood Park for the June 16, 2012 Powerball drawing. The winning numbers are 8, 14, 15, 16, 27 and Powerball 26.

If nobody claims the prize by next Sunday, exactly one year after the drawing, the money will become part of the next Powerball drawing.

Officials say the winner must sign the back of the lottery ticket and contact New Jersey Lottery headquarters immediately.
