Locards principle

Dr. Edmund Locard pioneered forensic science and he is remembered for his principle which states: Every object in contact leaves a trace on each other. Everyday we come into contact with different object as we go through with our work throughout the day, in doing so we leave traces of ourselves to where we have been. By using forensic techniques it can be established we have been there. The traces can be inform of fingerprints, sweat, hair, blood etc. that can be traced back to us.
