A 16-year-old boy was fatally shot in the Portage Park neighborhood Sunday afternoon.
Giovanni Matos was walking with two friends in the 5800 block of West Patterson Avenue when a gray car pulled up and an argument ensued about 12:50 p.m. Sunday, authorities said.
During the argument, a gunman exited the car and opened fire, police said.
Matos, of the 5500 block of West Henderson Street, was shot in the head and died at Advocate Illinois Masonic Medical Center hours later, authorities said.
Matos' friends ran away and were not injured, authorities said.
After the shooting, the gunman got back into the car, which drove away, police said.
Nobody has been charged for the killing.
Area North detectives are investigating the shooting as gang related after reports that gang slogans were yelled during the argument, police said.
