17-year old boy killed and 15-year old girl wounded in separate Chicago shootings

From an article:

While five people have been killed and at least another 36 wounded in shootings in Chicago since Thursday night, police Supt. Garry McCarthy sees the police department’s anti-violence strategy taking root, though he notes police are “basically treading water” in their efforts to stem the tide of violence. 

In a press conference Saturday afternoon touting a crackdown on two South Side drug markets, McCarthy said he sees the police department’s anti-violence strategy taking root. 

“We’re not winning, we’re not losing. We’re basically treading water,” McCarthy said. He said that in the month of August, “we had some trouble because some of these retaliatory shootings are happening quicker than we can stop them.”

A 17-year-old boy who was fatally wounded about 5:42 p.m. Friday in the South Side Grand Crossing neighborhood. 

The boy and a 42-year-old woman were standing outside in the 7900 block of South Drexel Avenue when someone riding a mountain bike fired shots at them, police said. Bullets hit the boy in the face and abdomen and the woman suffered a gunshot wound to the thigh. 

Paramedics took the boy to John H. Stroger Jr. Hospital of Cook County, where he was pronounced dead at 6:18 p.m., according to the Cook County Medical Examiner’s office. 

The woman was taken in good condition to Stroger Hospital, police said. 

Police said the motive for the shooting remained unclear, as witnesses were uncooperative with Area South detectives.

A 15-year-old girl who was allegedly smoking marijuana with a teenaged boy in the Far South Side Roseland neighborhood was critically wounded in what appeared to be an accidental shooting, police said. 

Shortly before 7 p.m., the girl was allegedly smoking pot with a teenage boy in the 0 to 100 block of West 112th Street, police said. The boy moved a gun, which fired and shot the girl in the chest, police said. 

Paramedics took the girl to the University of Chicago Comer Children’s Hospital at 6:59 p.m., where she was listed in critical condition, authorities said. Detectives were questioning the boy.

Every gun in the hands of a child must first pass through the hands of an adult.
