Fourteen city workers and one retired city worker in the western Ohio town of Piqua claimed a $207 million 12-state lottery prize today. As they had done twice a week for the past five years, the group pooled their money to buy Mega Millions Lottery tickets. Last Friday, a ticket bought at a Kroger changed their lives. "I'm going to set my mom and dad up for life," said Loyal Davis, who bought the ticket and then got the job of telling his co-workers they had won.
