Powerball jackpot reaches $1 billion, its second-highest prize ever, for Monday night's drawing

People showed up at convenience stores, groceries and gas stations across the country on Halloween hoping to find their own treat: a chance at Monday night's massive $1 billion Powerball jackpot.

Among them was Janice Turner, one of a steady stream of people — some wearing costumes — buying Powerball tickets at an outdoor kiosk in midtown Manhattan.

"I'm hoping to be the next billionaire," Turner said. "I think it's going to be lucky Halloween."
