The 6-month-old Chicago girl, Jonylah Watkins, who was shot five times while her father was changing her diaper, died of her wounds on Tuesday, Fox News reported.
Watkins died at Comer Children's Hospital, where she underwent surgery following Monday afternoon's attack, the Cook County Medical Examiner's office said. Her father, Jonathan Watkins, was also wounded and remains in critical condition at Northwestern Memorial Hospital.
Police on Tuesday were scouring the South Side neighborhood of Woodlawn, where the attack occurred in hopes of finding clues as to who carried out the attack. Witnesses said the gunman approached Watkins at around 1 p.m. and opened fire on him while he was standing beside his minivan changing his daughter's diaper.
Garry McCarthy, Chicago's police chief, said that Watkins underwent several surgeries and is in critical but stable condition. Jonathan was shot in the side and buttocks, suffering a graze wound to his face.
"This is another tragedy, because no child, certainly not an infant, should be a victim of gang violence," McCarthy said at a press conference Tuesday. "Although there are a lot of angles that we're pursuing, there are very strong gang overtones to this particular event."
Jonylah was shot five times, in the thigh, shoulder, lung, liver and bowels, the family said. The police chief indicated Jonathan was part of a gang in Chicago
"There's too much shooting over there," Jonylah's grandmother, Mary Young, told reporters Monday. "She's nothing but 6 months old. How could anybody -- what kind of heart?"
Chicago has seen a recent rise in largely gang-related gun violence, registering at least 500 homicides last year, according to police reports. In 2011, there were 435 homicides.
McCarthy also told reporters Monday that homicides were down 26 percent this year, compared with the same period a year earlier.
