Application of viewshed analysis and probability mapping for search area determination based on the Moors murders on Saddleworth Moor, the United Kingdom
Abstract:Geographical Information System (GIS) is underutilized within the forensic discipline, especially concerning the discovery of clandestine graves. GIS, viewshed analysis, and probability maps are being introduced into desk-based research both for archaeology and forensic purposes. This study aims to investigate how useful GIS can be to narrow down large search areas when locating clandestine graves. Combining GIS, viewshed analysis, and probability maps allows for the exploration of potential areas of concealme… Show more
“…A variety of different techniques, including ground-penetrating radar, sometimes in combination with electrical resistivity mapping, can now be used to assist in the location of buried remains 17,18 .

A study was undertaken at Forensic Science SA, Adelaide, South Australia, of all cases of homicide (January 2003–December 2022) where the victims' bodies had been concealed. Three hundred twenty-six homicides were identified, which included 27 cases where bodies had been deliberately hidden (8%) (age range, 2–82 years; ave, 34.9 years; M:F = 1.5:1). Deaths were due to blunt force trauma (n = 11), sharp force trauma (n = 4), asphyxia (n = 4), gunshot wound (n = 2), and a combination of drowning and asphyxia (n = 1). In 5 cases, the cause of death was not determinable. The methods of concealment (which were sometimes overlapping) included the following: dumping at a hidden/isolated location (n = 8), burial (n = 7), dismembering (n = 3), incinerating (n = 3), hiding in a wheeled garbage bin (n = 2), disposing in garbage resulting in the remains being located at waste disposal facilities (n = 2), hiding in a shed (n = 1), under a concrete floor (n = 1), in a suitcase (n = 1), in a river (n = 1), in a mine shaft (n = 1), and in a septic tank (n = 1). Although it has been asserted that concealed homicides are rarely encountered in forensic practice, the current study has demonstrated that the bodies in at least 8% of victims of homicide in South Australia have undergone some form of concealment.

Traditionally, forensic geophysics involves the study, search, localization, and mapping of buried objects or elements within soil, buildings, or water using geophysics tools for legal purposes. Recently, with the evolution of environmental crimes, forensic geophysics gave special care to detection, location, and quantification of polluting products. New techniques including the magnetic susceptibility have emerged to investigate this type of crimes. After discussing the state of the art of forensic geophysics, this chapter proposed the magnetic susceptibility as an efficient tool of environmental crimes detection. A case study of pollution detection was proposed from Tunisia. Being a fast and cheap technique, magnetic surveys represent a real promise for environmental forensic geophysics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
