Ok I see what the mixup is... we're talking about 2 different articles!
The one from the local news station states" As Anastasio tried to run away, police say the witness tried to stop him, which resulted in Anastasio punching the witness in the face, too. Officers say the witness "sustained pain and bruising" to his face, but he refused medical treatment." describing the 2nd attack on the witness, but "The man who was knocked unconscious is considered to be stable, NYPD said." about the original guy. "Stable" is a term that doctors/hospitals would use to describe a patient which semi implies that he was/is being treated. That's how I read it anyway
