The complaint said James Piezonka is a convicted felon and not allowed to possess any firearms.

The incident occurred in the westbound lanes of Route 120 in front of a residence.

A sedan, which was partially turned sideways in the roadway, and a motorcycle, which was lying on its side in the driveway of the residence, were part of the crime scene.

Court records show that James Piezonka and Ryan Piezonka both lived at the residence where police were seen investigating.

James Piezonka was transported to the McHenry County Jail and appeared in court Monday afternoon for an initial appearance hearing.

The McHenry County State’s Attorney’s Office filed a petition to detain Piezonka pending trial, calling him a real and present danger to the community.

McHenry County Judge Cynthia Lamb granted the petition and noted that James Piezonka is a convicted felon who was not supposed to possess a firearm. “In this case, he possessed a firearm and used it.”

Police have not released further details on what may have led to the shooting.

James Piezonka is scheduled to appear in court again on March 11 for a status of preliminary hearing.

The investigation continues by the Lakemoor Police Department, MIAT and McHenry County Coroner’s Office.
