Challenges in serial murder investigations involving missing persons

Abstract

Police agencies investigating serial murders involving missing persons face unique challenges. First, some missing persons are never reported missing or are reported missing long after they were last seen. Second, even when they are reported missing, some serial murder victims are not identified as such because police adhere to the theory that they died of causes other than foul play, or are still alive and have simply moved or run away. Finally, even when serial murder is suspected, the absence of forensic evidence can delay police in confirming that foul play is involved, therefore compromising or slowing the investigation. This article outlines how these investigative challenges have affected various North American serial murder cases. A better understanding of these challenges can help police managers and investigators in North America and internationally remain vigilant and prevent future investigative failures.
