Quote from Captain Stottlemeyer in Mr. Monk and the Astronaut
Natalie: She had drugs in her system? Barbiturates. Captain Stottlemeyer: Yeah, coroner says she took some pills. They didn't work. She went to plan B and dangled herself. It happens all the time. Adrian Monk: But you said yourself the crime scene didn't look kosher. Captain Stottlemeyer: Monk, what I'm saying is it might be murder, but it wasn't him.
