CHICAGO (AP) – A former Illinois Medical District commissioner, his wife and two other people used at least $3.7 million in state health grants to pay for vacation homes, yacht club memberships, luxury cars and other personal expenses, federal prosecutors said Friday.

Leon Dingle Jr., 75, and Karin Dingle, 73, both of Chicago, were indicted on charges of conspiracy to defraud, money laundering and mail fraud. Employee Jacquelyn Kilpatrick, 57, of Phoenix, Ill., and Edmond Clemons, 66, who lives at the same address as Kilpatrick, also were named in the 23-count indictment handed up late Thursday.

Phone messages seeking comment left at Dingle’s office and Kilpatrick and Edmonds’ home Friday were not returned.
