MODEL RELEASED. Forensic training. Scene of crime officer (SOCO) standing in woodland near a staged murder scene. The SOCO is wearing protective clothing in the form of a paper suit, overshoes (not shown) and a mask to prevent contamination of the crime scene. The SOCO is holding a clipboard, containing equipment used in the collection of evidence. The two L-shaped rulers are photographic scales which indicate the size, orientation and position of objects in photographs of the crime scene. 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.
