19-year-old jacob shauntee is one of the most perplexing for staff. >> every time staff does something you don't agree with it, this is what you do, you cut or tie or something, don't you? every time. because you just want everything to be fair, right? sorry, buddy. >> get this one right here on top. >> he's done it before, and it's shocking. his nail bed is purple. that's pretty bad. like i said, he's done it before. >> just two weeks ago officers and medical staff had their hands full with jacob during a meltdown in a time-out cell. tonight they frantically try to deal with his self-mutilation. >> where did you get this? is this from your mattress? >> no. >> is this from your mattress? what's it from, hon? >> hmm? >> you can tell me. i'm not going to say anything. what's it from? >> pillow. >> i thought we were trying to go home?
