CHICAGO (CBS) — A young man is dead, and a teenage boy suffered a graze wound to the face after two gunmen men in black opened fire Tuesday night in the Woodlawn neighborhood on the South Side.

No one is in custody early Wednesday, according to police News Affairs Officer Amina Greer.

The shooting happened at 7:55 p.m. at in the 6400 block of South King Drive, according to police News Affairs.

The two victims were outside when the assailants ran up to them on foot and fired, according to Grand Crossing District police Lt. Dale Kingsley. It was not immediately known if the two victims knew each other.

Edward Riley, 20, suffered multiple gunshot wounds at 6442 S. King Dr, according to the Cook County Medical Examiner’s office. He was pronounced dead at 10:17 p.m. at John H. Stroger Jr. Hospital of Cook County.

The second victim was a 15-year-old boy who suffered an apparent graze wound to the head, Fire Media Affairs Director Larry Langford said.

He was also shot in the hand, according to police News Affairs.

While Langford said the teen was initially in serious condition at University of Chicago Comer Children’s Hospital after paramedics learned the wound was deeper than expected, Kingsley said early Wednesday the boy was wounded in the face but did not suffer a life-threatening injury.

A third person, an adult, was taken to Saint Bernard Hospital after suffering an asthma attack, possibly prompted by the excitement of the shooting, Langford said.

Ambulances had a hard time getting to the victims because the street outside the apartment complex was full of people, Langford said. Police assisted in moving the crowd and the ambulances were able to make it out.

One of the victims was found shot in the courtyard of the building, while the other was found just inside the entrance, Langford said.

Police said the shooters were two black men who wore all black clothing.
