WOODSTOCK – The attorney for a sheriff’s sergeant who accused Undersheriff Andrew Zinke of interfering with a Drug Enforcement Administration investigation has connections to one of Zinke’s opponents in the 2014 election for sheriff.

On behalf of McHenry County Sheriff’s Sgt. John Koziol, Buffalo Grove-based divorce attorney Jonathan Nye filed a request for a special prosecutor to investigate Zinke. Nye previously represented Woodstock attorney James Harrison in a 2001 divorce case, court records show.

Nye and Harrison also attended John Marshall Law School together.
