The gray sedan was parked in the ambulance bay of the hospital, its doors open and bullet holes just above and below the driver’s side window.
Minutes earlier, 15-year-old Fabien Lavinder was in the car when someone stepped from an alley and shot him in the chest, police said.
The driver took the boy to the hospital, where he died shortly before 11 p.m. Tuesday.
Fabien was the 66th and final homicide last month, the deadliest May in Chicago since 1995, when 75 homicides were recorded, according to police records.
He was among nearly 400 people shot last month.
