  3. Early Forensic Applications • Bertillon’s System of Body Measurements—early method of identifiication

  4. Fingerprinting • Used for indentification beginning in early 1900s

  5. Blood Typing and Blood Analysis • Developed by Carl Landsteiner in early 20th century • Used for identification

  6. Locard Exchange Principle • When two objects come in contact with each other, a cross transfer of materials occurs • Believed that dust particle analysis could be used to solve any crime • His work caused the formation of crime labs to appear

  7. Crime Lab Departments or Services—Physical Science Unit • Chemical and physical tests • Identification of drugs, glass, paint, explosives, foreign powders, soil, and minerals • Analysis of trace evidence • http://www.youtube.com/watch?v=qlmZZoLGMpM&p=8865271F305ED39A&playnext=1&index=3

  8. Biology Unit • DNA profiling • Body fluid analysis • Hair and fiber analysis • Wood and plant analysis • Insect larvae analysis • http://www.youtube.com/watch?v=RCI9YhstHK4

  9. Firearms Unit • Examine firarms, bullets, shotgun shells, etc. • Garment analysis to see if gun has been fired • Mark identification by other tools and weapons • http://www.youtube.com/watch?v=WGHCTMTh7TE
