A 65-year-old woman has been declared dead and her family is working on donating her organs after a scooter crash near Mundelein on Wednesday, officials said.

The Lake County Sheriff’s Office and Countryside Fire Protection District responded around 1:20 p.m. Wednesday to the 26200 block of North Route 83 in unincorporated Mundelein for a traffic crash.

Sheriff’s deputies arrived and located a 65-year-old Mundelein woman with critical injuries.

Lake County Sheriff Spokesman Sgt. Christopher Covelli said that a preliminary investigation showed the female was operating a 2009 Motofino Scooter.

The woman was leaving the parking lot of the manufactured homes when — for an unknown reason — she drove slightly off the pavement.

This caused her to fall off the scooter and strike her head on a railroad tie, which was acting as a barrier between the pavement and grass, Covelli said.

The railroad tie had a spike protruding, which impaled the woman.

She was transported by ambulance to Advocate Condell Medical Center in Libertyville with critical injuries and reported to be in grave condition.

Lake County Coroner Dr. Howard Cooper said that the woman, whose identity is being withheld, was on life support and declared brain dead Thursday evening.

Her family is working with Gift Of Hope, a not-for-profit organization that coordinates organ and tissue donation, Cooper said.

An autopsy on the woman was conducted on Friday. Her identity will be released sometime following the autopsy.

The crash remains under investigation by the Lake County Sheriff’s Office Technical Crash Investigations Unit.
