CHICAGO — An ambulance happened upon a West Side shootout early Saturday morning that left two men in critical condition.
The ambulance was eastbound about 12:15 a.m. in the 3500 block of West Lake Street in the East Garfield Park neighborhood -- not responding to a call -- when the paramedics saw men ducking behind cars and firing guns, Chicago Fire Department spokesman Larry Langford said from outside John H. Stroger, Jr. Hospital of Cook County overnight.
Paramedics called a “10-1" over the radio, a term used to signal that a police officer, paramedic or firefighter is in distress and in immediate need of help.
