The driver of the Honda, a 26-year-old Rockford woman, and her passenger, a 34-year-old Elgin man, were both extricated from their vehicle by firefighters, the sheriff’s office said.

The two were flown by medical helicopter to Javon Bea Hospital in Rockford with life-threatening injuries.

Seatbelts were not worn by any of the occupants in either vehicle, the sheriff’s office said. Drugs are believed to be a contributing factor.

The investigation is ongoing by the McHenry County Sheriff’s Office Major Traffic Crash Investigation Unit.
