Winthropping as an investigative tool in clandestine grave discovery and psychological profiling

Missing persons cases are some of the hardest investigations to solve. The lack of forensic evidence impedes an investigation and critical time can be lost attempting to find the person or body. Recently, researchers have attempted to develop new approaches to help police in these types of investigations. The current paper continues research into Winthropping as a means of assisting police investigations when searching for clandestine, hidden graves and missing persons. A novel approach, using geocachers, to help inform Winthropping processes is outlined, and support gained through a survey of geocachers. The findings are then applied to a series of real-world homicides, including several serial killers. Analyses of gravesite locations in serial killer cases matched many of the features and properties outlined by geocachers. The results also indicate the potential of using Keatley and colleagues’ Winthropping as a psychological profiling as well as geographical profiling technique. Support was provided through the case of a murdered child who was later dumped. Recommendations for further research and application are provided.
