Watching rob during this episode is a clear indicator that he knows more than he says. He all but confessed within the last 10-15 minutes of the episode. How he mentions hes the only one that will possess her now. How he slept with the ashes, and how he had the funeral director rebuild her skeletal remains. Why have no profilers interviewed this lunatic? I'm willing to bet it was a murder for hire and that blue car is in a junkyard within a 200 mile radius.
