CHICAGO (WGN) - Authorities say a teenage boy is dead after his sister became upset about a post on Facebook.
Diaz' stepfather, Ralph Otero, says the teen snuck out of the house with his two older sisters because they wanted to confront someone about a post on Facebook.
Otero says one of the boy's sisters was arguing with someone about a post on Facebook.
Diaz's sister decided she wanted to confront the other person and Anthony decided to follow her.
Otero says the post had nothing to do with Anthony and he was recording the fight when he was shot.
Police say someone shot him in the side and at least one of the bullets exited through his chest.
So far, no arrests have been made.
