valentine -- >> though gary valentine found the shank and attempted to dispose it, he said it wasn't his. >> as i was going through an old box it look tattered and looked to be a piece of plastic. we have a lot of broken pallets and do tie saran wrap, but that particular day it was more than it appeared. >> step in and step all the way to the back wall. >> valentine is also placed in confinement but believes he has a solid defense since he was with an officer when he found the shank. >> i don't see how you can charge me with something, i had a staff member next to me an we discovered it at the same time. it would be asinine for me to put it there and say, look what i found, come on. if i had anything to do with it, smart money would have been to leave it alone. when we got back to the pod, people said explain what it was used for and be done with it. >> was that a particular person? >> yes, it was. >> can you tell me who that person was? >> they did their investigation, i'm pretty sure they got the guy. >> dean says he knows exactly why the other inmates blamed him for the shank. >>
