Quote from Captain Stottlemeyer in Mr. Monk and the Big Game
Julie Teeger: If DNA is like a fingerprint, then why can't you solve every single case? Captain Stottlemeyer: First of all, we do not find DNA at every crime scene. And even if we did, you have to have something to match it against. There was a young woman. She wasn't much older than you. What was her name? Remember, a couple years ago. Lieutenant Disher: Oh, uh... Captain Stottlemeyer: The Irish girl. McGoohan. Lieutenant Disher: McGoohan. Captain Stottlemeyer: Paula McGoohan. Lieutenant Disher: Paula McGoohan. Captain Stottlemeyer: We found her body in the middle of a golf course. There was a ton of DNA at the scene. And, uh, we ran it through the system, but we couldn't get a hit because there wasn't anything to match it against. Lieutenant Disher: Do you have any multiple choice, Julie?
