    1. Forensic Science Disciplines from the American Academy of Forensic Sciences

    2. Forensic Science 10 Disciplines of Forensic Science

    3. Forensic Science Criminalistics Analyze, compare, identify and interpret physical evidence. Criminalist must “objectively” apply techniques of physical and natural sciences to examine physical evidence.

    4. Forensics Types of evidence Microscopic (too small to see, i.e. cells) Macroscopic (Truck) Hair Fibers Blood Seminal and body fluids Alcohol drugs

    5. Forensics Types of evidence cont. Botanicals Soil Flammables Bullets Tool markings Footprints Smeared or smudged markings

    6. Forensics Engineering Forensic Sciences Applies principles of mathematics and science to solve crimes. Examples of subjects: Failure analysis Accident reconstruction Causes and origin of fires and explosions Design review Quality evaluation (construction, manufacturing)

    7. Forensics General Forensics Laboratory investigation Field investigation Clinical work Communication Computer investigation Education Research Speech scientist

    8. Forensics Accountant Archeologist Artist/sculptor Aviation accident investigator Ballistics analyst Computer related crime investigator Computer specialist Photographer Polygraph examiner Radiologist

    9. Forensics Jurisprudence Judge Defense attorney District Attorney

    10. Forensics Odontology Forensic dentistry Identification Bite mark identification

    11. Forensics Forensic Pathology/Biology Pathology = Study of Disease Coroners performs autopsies: Examine tissues under microscope Analyze body fluids, i.e. blood, urine, stomach contents Determines cause of death

    12. Forensics Investigates deaths Homicides Accidents Suicide Unattended deaths Sudden death Deaths in police custody Unusual deaths

    17. Forensic Science Techniques used: Chemical analysis Physical analysis

    18. Forensic Science Forensic Toxicology Studies harmful effects of chemicals or drugs on living systems Often has minute sample to analyze Alcohol Narcotics Depressants Stimulants Hallucinogens
