WOODSTOCK – An internal investigation of Undersheriff Andrew Zinke found that he did not violate any McHenry County Sheriff’s Office general orders when he spoke to a friend about a federal drug investigation.

Sgt. John Koziol alleged in court documents that Zinke tipped off the owner of a Crystal Lake business that was part of a U.S. Drug Enforcement Administration investigation into the transportation of thousands of pounds of marijuana.

That owner, Brian Goode, is a close friend of Zinke, as well as a contributor to Zinke’s campaign for sheriff in 2014.
