A 7-year-old boy has become the latest reminder of Chicago's ongoing struggle to combat gun violence and the gangs that police say are responsible for so much of it.

After Amari Brown was shot to death Saturday night, Police Superintendent Garry McCarthy told reporters that investigators believe the intended victim was the boy's father — a known gang member with a long history of arrests. He said Brown is not cooperating with detectives

He also said the boy would still be alive had Brown remained in custody after his arrest in April on a gun possession charge and not been able to post bail the next day.

Brown's family disputed McCarthy's contention that Brown was the intended victim and that he bears any responsibility for his son's death.
