and then he kept hitting me until i blacked out. i could feel one hitting me here, one in the body and one on this side. two on this side and one on this side, but i never saw their faces or their bodies. >> tell me, what did the doctor say about your injuries? >> oh, nothing, it's just -- got a skull fracture right in here. everything else is all right. >> because of limited surveillance in the gym, no officers witnessed the assault. and due to prison politics, inmates refused to talk. >> in our search this trash can contained clothing that had blood on the bottom of the boots and on the side of the boots. >> whether it was checking for some reason, maybe he knows somebody, disrespect, something like that may have happened. okay?
