Their bodies were found inside an SUV parked on the 6900-block of South Stewart Avenue. Police say the victims -- both African-American men in their 20s -- had suffered multiple gunshot wounds.
The Cook County Medical Examiner's Office says the relatives of the two men have been notified, but that their names won't be released until their families make formal identification of the bodies.
Wentworth area detectives are investigating.
