Forensic investigation is the application of science to criminal and civil laws. GPR is an effective tool for Forensic investigations. It helps us collect, preserve, and analyze buried evidences during the course of an investigation. It works well for human remains; it may help law enforcement personnel find hidden graves of victims months after a murder. GPR can assist in locating evidence behind brick or concrete walls, wooden floors or in hidden compartments. GPR detects areas of disturbed soil and non-metallic objects that are nearly undetectable using other subsurface investigation tools. GPR locates buried bodies, guns, knives, buried drugs or money, explosives, disturbed soil, tunnels and chambers. Ground penetrating radar can aid in ruling out suspect areas in minutes.
