WOODSTOCK – After allegations that Undersheriff Andrew Zinke tipped off a close friend about a federal drug investigation, a judge declined to appoint a special prosecutor and now the McHenry County State’s Attorney’s Office says Zinke broke no laws.

Sgt. John Koziol alleged in court documents that Zinke tipped 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.

Koziol sought a special prosecutor to investigate Zinke, which Judge Thomas A. Meyer denied last month, saying there was no per se conflict between the sheriff’s office and the state’s attorney’s office.
