At Monk's request, the medical examiner turns Webster's body over, and he mentions that drowning is the likely cause of death. The wounds on his body, while still extremely painful, are not fatal, and they appear to have been made by a creature of some sort. After Randy makes several wild guesses about what kind of animal could make a bite like the one on the body, (his guesses getting more bizarre until he guesses that a clam is responsible) Monk dismisses him and tells all that the animal that did this was an alligator. He points out that all of the teeth marks are identical, as alligators have teeth that are all perfectly identical. The medical examiner points out to Monk that alligators are not indigenous to San Francisco, but an alligator may have been responsible - after all, alligators kill their prey by grabbing them with their mouths, and then holding them underwater until they drown, and the pattern of injuries is consistent with this theory. Monk, Natalie, Stottlemeyer and Disher are all convinced that this is a rather cleverly committed homicide.
