Researches have recently experimented with usage of near infrared (NIR) technology together with drones to search where buried bodies are. Drones can facilitate research in forensic science and make the investigation much safer and more effective than sending humans into the field. As the body decomposes it excrete specific nutrients into the soil. Researchers study if the NIR technology installed on drones can effectively locate human remains. If the technology proves to be successful, in the future drones may be used to locate hidden graves of individual homicide victims, or mass graves.
