the isu team has come to a conclusion regarding carlton moran's involvement in the "a" yard assault. >> he's a white boy, the assault happened with the south siders, so mexicans. he was -- we pretty much ruled him out as being a suspect. usually when they do a check in, as they call it, it would be their own race that does it. we have a few cis, confidential informants, that are reliable which stated why it occurred. it pretty much eliminated moran from being a suspect. what we'll do is we'll close it out. we'll do a confidential or closure chronos. we'll submit that to committee. and they'll make a decision. we pretty much have a knowledge of who it might be. we're trying to gather more evidence and more facts on that. >> carlton was subsequently released from ad seg but declined to talk to our producers any further due to fear of retaliation.
