Quote from Adrian Monk in Mr. Monk and the 12th Man
Lieutenant Disher: We just came from his house. There was a body part in the freezer. A human finger. Captain Stottlemeyer: Really? Oh, the D.A.'s gonna love that. They love body parts in the freezer. Adrian Monk: But none of the victims were missing a finger. Captain Stottlemeyer: Yeah, well, uh, he killed somebody else. I mean, that's why they call them "psychotic." Adrian Monk: Why would he wait six years, and then kill everybody else on the jury?
