Knowing what signs to look for helps both forensic scientists and the families of the deceased in the ongoing search for missing cartel victims. The Jalisco Nueva Generación cartel is behind the murder and disappearance of thousands of victims who are often never found. This is why the Jalisco Search Commission is trying to learn more about identifying hidden bodies by dressing up pig cadavers in human clothes and burying them. Other elements released as pig cadavers decompose, such as nitrogen and potassium, are detected by drones with hyperspectral cameras that measure light signatures from substances in the ground. They also analyze soil samples from the pig graves and compare the to those from human graves.
