John Robert Williams may be the most disturbed, cold hearted killer Phil has encountered in his 30 year career. With a life of crime and murder in his past, Williams sits in a Mississippi prison for the murder of only one victim. The authorities are aware he has killed at least 10 more victims and is a key suspect in numerous open cold cases, but they are happy to have him off the streets for life. With his murders came torture, rape, and mutilation of the corpses, all for pure enjoyment. Williams was arrested, along with his girlfriend, in 2005, after a year-long investigation by local and federal authorities into a string of cross-country murders.

In this episode, John Williams speaks with Phil on a contraband cell phone that he had smuggled into prison. John confesses to a high profile mass-murder and surprises Phil with information about someone close to him and their participation in his disturbing life of crime.
