 What is forensic science?  What are some of the major analysis areas in forensic science?  JWQ JWQ

 Bertillon’s System of Body Measurements— early method of identifiication

 Used for indentification beginning in early 1900s

 Developed by Carl Landsteiner in early 20 th century  Used for identification

 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

 Chemical and physical tests  Identification of drugs, glass, paint, explosives, foreign powders, soil, and minerals  Analysis of trace evidence  atch?v=qlmZZoLGMpM&p= F305ED39A&playn ext=1&index=3 atch?v=qlmZZoLGMpM&p= F305ED39A&playn ext=1&index=3

 DNA profiling  Body fluid analysis  Hair and fiber analysis  Wood and plant analysis  Insect larvae analysis  com/watch?v=RCI9Y hstHK4 com/watch?v=RCI9Y hstHK4

 Examine firarms, bullets, shotgun shells, etc.  Garment analysis to see if gun has been fired  Mark identification by other tools and weapons  com/watch?v=WGHC TMTh7TE com/watch?v=WGHC TMTh7TE

 Analyses handwriting, types of printing  Examines impressions, paper, and ink types  e.com/watch?v=u1l rid2nobM e.com/watch?v=u1l rid2nobM

 Takes photographic evidence at crime scene  Infrared and ultraviolet imaging  e.com/watch?v=0M LY3_6O15o e.com/watch?v=0M LY3_6O15o

 Examines body fluids and organs to look for drug presence  e.com/watch?v=cp0 9mWY8Buk e.com/watch?v=cp0 9mWY8Buk

 Examines evidence for latent fingerprints  e.com/watch?v=Hs RUY6twUX4 e.com/watch?v=Hs RUY6twUX4

 Used more in questioning than forensic analysis  e.com/watch?v=GL L3wtgBiFA e.com/watch?v=GL L3wtgBiFA
