This is heart breaking

Thursday afternoon in Chicago a father of two young kids was talking with the kids mother as she and the children were in the van parked in front of their home. Two teens approach the father and asked what set do you belong to in other words what gang do you ride with. The man replied , I'm with my kids. That's when one teen told the other , shoot that n_____ ! The mother pleaded with the teens saying , he is with his kids but the same teen response was , shoot that n_____! Other parents on children who were out on the same block were caught in a moment of shock. Police have no suspects in custody as of yet but the children of the father had to witness their father being gun down right before their very eyes.
