SPRINGFIELD, Ill. (AP) — A Chicago woman has been sentenced to three years in federal prison for her role in stealing millions of dollars in state grant funds.

U.S. District Judge Richard Mills imposed the sentence on Karin Dingle on Monday after sentencing her husband, Leon Dingle Jr., to six years in the case.

The 76-year-old Karin Dingle was convicted last December on six counts of conspiracy, mail fraud and money laundering. Prosecutors say she and her husband pocketed at least $2.9 million of more than $9.6 million in Illinois Department of Public Health grants from 2004 to 2010.

The 78-year-old Leon Dingle was convicted of 17 counts in the scheme.

Prosecutors say they used the money to pay for luxury cars, vacation home renovations and a $95,000 payment on their son’s mortgage.
