A 21-year-old woman died after she and a second person, who was flown to the hospital, were critically injured in a crash with a semi-truck on Interstate 90 in Huntley Thursday morning.
The Huntley Fire Protection District and Illinois State Police responded around 4:30 a.m. Thursday to Interstate 90 near Route 47 for a report of a vehicle crash with injuries.
Huntley Fire Protection District Public Information Officer Alex Vucha said fire crews arrived and located a two-vehicle crash in the westbound lanes of Interstate 90 just west of Route 47 near the 46.25 mile marker.
A semi-tractor-trailer truck and a Chevrolet Malibu, which sustained heavy damage, were involved.
The sedan sustained major damage and came to rest off the roadway.
Firefighters determined that minor extrication was required to remove two occupants from the sedan, Vucha said.
The passenger of the Chevrolet was reported to be unresponsive at the scene.
Vucha said both victims suffered serious to critical injuries that were believed to be life-threatening.
Ambulances transported them to Northwestern Medicine Huntley Hospital. State police said those two included the driver and a passenger.
The McHenry County Coroner’s Office confirmed that one of the victims, a 21-year-old woman, died in the hospital.
The coroner’s office has scheduled an autopsy on the 21-year-old woman for next week. Her identity is being temporarily withheld.
A LifeNet medical helicopter was called to the hospital helipad to transport the second victim due to the extent of their injuries, Vucha said.
The helicopter flew that victim to Advocate Condell Medical Center in Libertyville for trauma care, Vucha said.
State police did not have an update on the condition of the surviving victim.
The driver of the semi-truck was uninjured. The semi-truck was reported to be leaking fuel into the ditch following the crash.
The westbound entrance ramp from Route 47 to Interstate 90 was shut down for several hours while emergency crews operated at the scene and the crash was investigated.
Two right lanes of westbound Interstate 90 were shut down. All lanes were reopened around 10:30 a.m.
The cause of the crash remains under investigation by the Illinois State Police.
