Overview of the Course

  • Course Description: This course will teach an understanding of the fundamental theories of physical evidence, practically applied; and the legal consideration involved in its recognition, collection, preservation and presentation in court. Physical evidence includes such things as fibers, glass, hair, soil, bullets, fingerprints, and shoeprints. Learn the appropriate methods for processing, securing, and isolating a crime scene. Topics include recording the scene, searching for evidence, decision-making about what evidence is appropriate and necessary to collect, procedures for collecting physical evidence, and maintaining the chain of custody to avoid contamination.

Role of the Crime Scene Investigator

    • “Crucial” step in investigation
    • Four Basic Fundamental Concepts
      • Secure- preserve evidence, safety
      • Search – Critical v Supporting v Property
      • Record – sketching, measuring, photography, videography etc
      • Reconstruct- final goal
    • From the analysis of the crime, an experienced CSI will determine what type of physical evidence, where and how to recognize it, how best to collect, preserve and process the evidence and combined with laboratory examinations, reconstruct the crime

Crime Scene Notebook Guidelines

  • Handouts on format
    • Need to use proper format: Abstract, Introduction, Materials and Methods, Results, Discussion with conclusions, References, Appendices
  • Handouts on Self Evaluation (Begin with the end in mind)
    • Administrative Review
    • Technical Review
  • Examples of A, B and C Laboratory Notebooks
    • You will have your notebooks at every class sessions
    • At any session, I may select 1 notebook per group to “grade”. In this way you will get feedback early in the semester to follow.
    • I will be providing a portion of the CSI exercise grade from group participation

Crime Scene Investigation Goal- reconstruct the crime

Locard’s Exchange Principle

  • Contact results in a cross-transfer of evidence
  • 1910 Edmund Locard, successor to Lacassagne as professor of forensic medicine at the University of Lyons, France, established the first police crime laboratory.

Overview of the types of Physical evidence

  • Blood, semen, saliva
  • Documents
  • Drugs
  • Explosives
  • Fibers, Hair, Paint
  • Fingerprints
  • Firearms and ammunition
  • Glass
  • Impressions
  • Organs and physiological fluids
  • Pertoleum produts
  • Plastic bags
  • Rubber, other polymers
  • Powder residues
  • Serial numbers
  • Soil and minerals
  • Tool marks
  • Vehicle lights
  • Wood and other vegetative matter

CSI Exercise 1- Measurements and Documentation

  • In your small teams using the rulers you have been provided, measure to the nearest 0.1 mm the crime scene object for your team.
  • Team leaders should collect all measurements on one paper. Write down the range of measurements (eg 10.3-10.7mm) and calculate the average measurement.
  • In addition, take measurements to document the location of the object.
  • Once completed be sure everyone signs the paper and hand it in.

CSI Measurement Questions

  • Did you all agree on the measurements?
  • If no, what are 3 reasons which may cause the discrepancy?
  • For one of the reasons, design an experiment to test your hypothesis.
  • Is there enough documentation for you to reconstruct the location of the crime scene.

Office Hours Policies

  • Set up 15 minute appointments by email steven.lee@sjsu.edu
  • Benefits (to you and me)
    • Review the course material.
    • Show me how hard you are working
    • Provide feedback
    • Ask specific questions or Ask for help
    • Extra credit may be provided for coming to discuss questions on the reading, exams, DNA, assignments, forensics, news articles, department, college and campus scholarships…etc
