The crash occurred about 9:45 p.m. Wednesday in the 17000 block of Route 176, about a half-mile east of North Union Road near Union. It was one of two fatal crashes that occurred overnight in McHenry County.
Sarah E. Wells, 27, of Rockford died of blunt trauma to the head, neck, chest, abdomen and pelvis, McHenry County Coroner Anne Majewski said.
Union Fire, Marengo Rescue and the McHenry County Sheriff’s Office responded to the scene. Wells was driving west in a 2005 Honda Civic when she crossed the center line and hit a 2007 Jeep Cherokee, police said.
The Marengo man driving the Jeep was critically injured in the crash and taken to Centegra Hospital – Huntley and later transported to Advocate Lutheran General Hospital in Park Ridge. His condition was not known Friday afternoon by Majewski’s office.
Cellphone use is suspected as a contributing factor, according to police, and the crash remains under investigation.
