Excerpts from cbsnews.com:

A Skokie Fire Department ambulance transporting a critically ill patient to the hospital was involved in a crash with a car near Gross Point and Golf Road Saturday morning. 

Paramedics performed CPR on the patient until another ambulance could arrive. The patient later died at the hospital. Police do not believe the crash contributed to the patient’s death. 

No one else was hurt in the incident.
