The fight was over a pair of gym shoes at night on the south side of Chicago.
And this is what came of it.
One teenager faces years in prison.
Another, a boy of just 15, is dead.
The incident might not have even made the news, except the victim was the grandson of a long serving congressman.
At a press conference, that congressman Danny Davis did something unusual.
He grieved not just for his own grandson, but for his grandson's killer.
I grieve for my family.
I grieve for the young man who pulled the trigger.
I grieve for his family, his parents, his friends, some of whom will never see him again.
It is so unfortunate when these tragedies continue to occur and reoccur.
And somehow or another, our society has not been able to find and exact the answers and solutions.
The solutions we do have often produce more disputes than results.
Conservatives call for harsher sentencing and better policing.
Liberals want gun control and more social service programs.
One thing's even as we argue, people are dying.
In 2016, Chicago had the highest number of killings in two decades.
762 people were murdered.
What can be done?
Well, one community group has an unusual idea.
