Police identify 71-year-old Johnsburg man as victim of McHenry Home Depot crash

A 71-year-old Johnsburg man has been identified as the pedestrian who was struck by a truck while walking into a McHenry Home Depot on Sunday and later died, Public Affairs Officer Patrick Polidori said.

Officers responded at 12:41 p.m. Sunday to the Home Depot store, 2461 N. Richmond Road, according to a news release from McHenry police sent Monday.

An investigation determined that William Dammeyer was struck by a 2008 GMC Sierra HD pickup truck that was traveling near the entrance of the store. Police said 19-year-old Christian J. Zientko of McHenry was driving the truck.

Dammeyer had been taken to Northwestern Medicine McHenry Hospital and then flown via Flight for Life to Advocate Condell Medical Center in Libertyville.

McHenry Township Fire Protection District Battalion Chief Kevin Sears had said the victim suffered serious and multi-systemic injuries after he was hit. McHenry police learned Monday that Dammeyer had died, according to the release.

Zientko was cited for disobeying a stop sign, according to the release. Polidori said additional charges may be filed, pending the results of an ongoing investigation.

McHenry police’s Major Crash Assistance Team – composed of officers from the McHenry Police Department, Johnsburg Police Department, Spring Grove Police Department and Woodstock Police Department – are continuing to investigate this incident, according to the release.

Anyone with information related to this incident is asked to call McHenry police's Criminal Investigation Division at 815-363-2599. Anonymous tips can be left on McHenry police's tip line at 815-363-2124.

The Lake County Coroner’s Office said preliminary autopsy results would be released later Monday.
