MODEL RELEASED. Forensic training. Scene of crime officers (SOCOs) inspecting the shallow grave of a dummy representing a murder victim (left). The SOCOs are wearing protective clothing in the form of paper suits, overshoes and masks to prevent contamination of the crime scene. Metal platforms (right of dummy) are used by the SOCOs to walk across the site, preventing destruction of evidence. SOCOs provide scientific support to police forces. They establish what evidence is required from a crime scene and the best way to obtain it. Photographed on a training course.
