Locard’s Principle
Mock Crime Scene Investigation
“Golden Rule” of Crime Scene Investigation/Management
“Never touch, change, or alter anything until it has been documented, identified, measured,
and photographed…when a body or article has been moved, it can never be restored to its
original position.”
“Physical evidence can’t lie, quit, die, forget, or get fired.”
“Testimonial evidence may change or source may become ‘nonexistent’ between original and
court version.”
