Forensic science is a multidisciplinary field that combines various scientific disciplines to solve crimes. One of these disciplines is forensic geomorphology, which uses the principles of geology and geomorphology to investigate criminal activities that occur on or near the landscape.
What is Forensic Geomorphology?
Forensic geomorphology is the application of geological and geomorphological knowledge to legal issues. This field applies the principles of geology and geomorphology to solve crimes that occur on or near the landscape. Forensic geomorphologists use their knowledge of landforms, erosion, sedimentation, and soil to understand how natural processes can affect evidence and how evidence can be used to reconstruct events.
How is Forensic Geomorphology Used in Criminal Investigations?
Forensic geomorphology can be used in various criminal investigations, including homicide, robbery, and environmental crimes. Forensic geomorphology can help investigators determine the locations of crime scenes, reconstruct events, and identify potential sources of evidence.
Forensic geomorphology uses various methods to investigate criminal activities that occur on or near the landscape. Some of these methods include soil, erosion patterns, sedimentation, and landform analyses. By using their knowledge of these processes, forensic geomorphologists can identify potential sources of evidence and reconstruct events to help solve crimes.
- Soil analysis is a process where forensic geomorphologists use their knowledge of soil types and characteristics to identify the origin of soil samples found on a suspect’s clothing or vehicle. This method can help investigators understand the link between the suspect and the crime scene.
- Erosion pattern analysis studies the movement of soil and sediment caused by water or wind. Forensic geomorphologists use this method to determine the direction of water flow and the potential locations of evidence that may have been washed away.
- Sedimentation analysis is another method used in forensic geomorphology. It involves studying the deposition of sediment in a particular area. Forensic geomorphologists use this method to identify potential sources of evidence that may have been transported by water or wind.
- Landform analysis is the study of the landscape’s natural features, such as mountains, valleys, and rivers. Forensic geomorphologists can identify potential sources of evidence and reconstruct events to help solve crimes by analyzing landforms.
Case Studies
Forensic geomorphology has been used in many high-profile cases to help solve crimes. Some of the examples are:
One notable example is the case of the “Boston Strangler.” In the early 1960s, a series of murders occurred in the Boston area. The killer, who became known as the “Boston Strangler,” was never caught. However, in 2013, forensic geomorphologists used soil analysis to link the killer to the crime scenes. The analysis showed that the soil on the suspect’s clothing matched the soil at the crime scenes.
Next, is the case of the “Green River Killer.” In the 1980s and 1990s, a series of murders occurred in the Seattle area. The killer, who became known as the “Green River Killer,” was eventually caught and convicted. However, forensic geomorphology played a critical role in the investigation. Forensic scientists used soil analysis to identify the burial sites of some of the victims.
Another example of the use of forensic geomorphology is the case of the “Lady in the Lake.” In 1969, the body of a woman was found in a lake in Pennsylvania. The woman, who was eventually identified as Carol Ann Dougherty, had been strangled and her body was thrown into the lake. Despite an extensive investigation, the case went cold for over 30 years. However, in 2003, forensic geomorphologists used sedimentation analysis to determine the location where the killer had thrown the body into the lake. This information led investigators to a suspect, who was eventually convicted of the murder.
Forensic geomorphology has also been used in the investigation of the assassination of President John F. Kennedy. In the 1990s, a group of forensic scientists used landform analysis to study photographs and films of the assassination site. They concluded that the shots that killed President Kennedy came from a different location than the one identified by the Warren Commission.
These cases illustrate the important role that forensic geomorphology can play in solving crimes and providing answers to long-standing mysteries.
Conclusion
Forensic geomorphology is an important tool in the field of forensic science. It provides investigators with a unique perspective on criminal activities that occur on or near the landscape. By understanding the principles of geology and geomorphology, forensic scientists can use natural processes to help reconstruct events and identify potential sources of evidence.
