 The team flies to Tampa where a disappearance is believed to be the work of businessman Mark Gregory, who was never convicted but presumably tortured and drowned at least four women. His house proves better equipped for disguises then most theaters. As he is found to have left another body in a Georgia hotel where he checked in under his own name, the team believes this is his last, most aggressive phase, no longer giving priority to covering his tracks. They revise his profile after studying his family history, which his indulgent father always pushed away.
