The search for missing people is a complex and intensive undertaking. Predictive models (such as RAG mapping and geographic profiling) in combination with drone-mounted technologies can improve these searches by driving down time and monetary costs, gathering new types of data and reducing the need for investigators to expose themselves to dangerous environments. Promising technologies to discover traces of clandestine burials in the landscape are LiDAR, RGB photography, multispectral and hyperspectral imaging, as well as infrared/thermal photography. This review covers the existing literature on these techniques and discusses future opportunities and directions.

Forensic mycology and palynology are emerging disciplines that offer valuable tools for solving crimes, particularly in cases of enforced disappearances and clandestine burials. This study, conducted in Bogotá, Colombia, aimed to explore the potential contributions of mycology and palynology in forensic investigations. Using a controlled experimental setup, we simulated clandestine graves and studied the fungal and pollen communities at different soil depths, aiming to identify decomposition markers and estimate burial times.

Here, we investigate the microbial and elemental signatures left behind at the sites of relocated remains, providing insights into postmortem processes that can assist forensic investigations of clandestine burials and relocated remains. We allowed two 90.7 kg (200lbs) clothed porcine models to decompose in open, varied environments in Arizona for a period of 25 days prior to the removal of the remains to secondary burial locations.

Locating a clandestine grave is a challenging yet crucial step in a criminal investigation and eventual prosecution. Many techniques have been used to locate clandestine graves, including light detection and ranging and ground penetrating radar. Recently, thermal imaging has also been evaluated as a method for this task.

Rigorous field assessment in different soil types and climates comparing simulated graves with pig remains and human remains are needed to assess the capabilities and limitations of electrical resistivity tomography (ERT) as a tool to search for unmarked graves. Our study assesses the ERT signals from graves with pig and human remains in a cold, humid continental climate with sandy soils. Two sets of three experimental graves were established: the first set consisted of two graves containing human remains and an empty grave serving as a control, while the second set consisted of two graves with pig remains and a second empty grave.
