A Wonder Lake woman and a McHenry man both died after suffering critical injuries when their motorcycle rolled over in unincorporated McHenry last week.

An autopsy showed the driver, Timothy Barry, 56, of McHenry, died as a result of blunt force injuries sustained in the crash, according to Lake County Coroner Jennifer Banek.

He was pronounced dead on Friday at Advocate Condell Medical Center in Libertyville. Toxicology results are still pending.

The passenger, Tanya Davidson, 50, of Wonder Lake, died at Loyola University Medical Center in Maywood Friday morning.

The McHenry County Sheriff’s Office and Nunda Rural Fire Protection District responded around 6:06 p.m. August 25 to the 2600 block of South Justen Road in unincorporated McHenry for a report of a single-vehicle crash.

The Prairie Grove Police Department, McHenry Police Department, McHenry Township Fire Protection District, Cary Fire Protection District and Crystal Lake Fire Department were also called to the incident.

A preliminary investigation showed that a 2003 Harley Davidson motorcycle, driven by Barry, was traveling northbound on Justen Road.

For unknown reasons, he failed to navigate the curve in the road, resulting in the motorcycle leaving the roadway and crashing, according to the McHenry County Sheriff’s Office.
