  11. LOOK AWAY

  12. Albert Osborn • Developed the fundamental principles of document examination. Handwriting  ”Evidence" in the Lindbergh Case

  13. Walter McCrone • Utilized microscopy and other analytical methodologies to examine evidence. • Found titanium in paint, proving the Vinland map a forgery Vinland map

  14. Hans Gross • Wrote the first treatise describing the application of scientific principles to the field of criminal investigation. • Father of modern criminalistics.

  15. Edmond Locard • Incorporated Gross’ principles within a workable crime laboratory. • Exchange Principle - Trace evidence is based on Locard’s Exchange Principle which contends that every contact, no matter how slight, will leave a trace. The trace is normally caused by objects or substances contacting one another, and leaving a minute sample on the contact surfaces.
