Crime Scene Examination

Crime scene investigators document the crime scene. They take photographs and physical measurements of the scene, identify and collect forensic evidence, and maintain the proper chain of custody of that evidence. Crime scene investigators collect evidence such as fingerprints, footprints, tire tracks, blood and other body fluids, hairs, fibers and fire debris.

NIJ funds projects to improve:

• Identification of blood and other body fluids at the scene.
• Field detection of drugs and explosives.
• Preservation of evidence.
