Mr. Monk and the Really, Really Dead Guy

S5, E15: It's near midnight and a street musician is getting ready to go home. Unfortunately, it's not the musician's night. As he walks down a dark alley, an attacker emerges and whacks him over the head with a tire iron. But the attacker is not finished. He proceeds to suffocate, poison, stab, shoot, and crush the musician, killing the victim six different ways in all. The man who killed the street musician left a note identifying himself as the "Six-Way Killer," and the note promises that he will strike again in 36 hours. The federal government is taking over the case, and the Deputy Police Commissioner orders Stottlemeyer, Disher, and Monk to assist the man in charge of the federal investigation, Agent Thorpe.
