Quote from Captain Stottlemeyer in Mr. Monk's Other Brother
Captain Stottlemeyer: Oh, by the way, the prisoner you were asking about, the cellmate? Adrian Monk: Shiv Logan? Captain Stottlemeyer: Yeah. You better start knockin' on a different door, because they just now found him dead in the prison rec room. He was stabbed in the neck with a shiv. Guy should have picked a different nickname. Well, you kids have fun. Nighty night.
