This includes a camera (upper right) for photographing the scene of a crime, numbered markers (bottom centre) for marking the position of evidence at the scene, a fingerprint detection kit (lower right), a ballistics trajectory reconstruction kit (lower left) and tools used to sift through soil (lower centre).
