      • Is any item or information gathered at the scene of a crime, or at related locations which tends to disapprove or establish something.
      • It can be divided into two general goods:
      Testimonial Evidence
      Physical Evidence
    • Testimonial Evidence
      Statement made under oath
      It’s said in court by a competent witness.
      Also called direct evidence
    • Important factors to take in account with eye witness
      Type of crime & how witness saw it.
      Memory (ability to remember characteristics. Ex: hair, color, sex, age height, reliving event, if their was a presence of weapons.)
      Interviewing techniques (open ended questions)
      Relationship of witness to suspect
      How much time has passed between offense and id.
      If the witness id the defendant.
      ***** Most known cases of an innocent person being convicted has happened due to a mistaken eye witness.
    • The Innocence Project
      National Organization dedicated to exonerating wrongfully convicted people through DNA evidence.
      Number 1 cause of wrongfully convictions nationwide is because of eye witness misidentification.
    • Jeffrey Dahmer Case
    • Physical Evidence
      Tangible tend to prove or disapprove a fact
      Real evidence
      Refers to any item that would be present at the crime scene on the victims out found in a suspects possession.
      more reliable than testimonial evidence
      Can be any material or object in any shape, size, form.
    • Physical Evidence
      Types of Physical Evidence:
      Trace Evidence
      Transient Evidence
      Conditional Evidence
      Indirect Evidence
      Individual Evidence
      Class Evidence
    • Trace Evidence
      • refers to physical evidence that is found in small but measurable amounts. (For example: hair, fibers, skin cells, DNA, blood, etc.)
    • Transient Evidence
      • temporary evidence can be easily changed or lost. Recorded at the time by usually the first office at the scene. (For example: odors, temperature, imprints, etc)
    • Conditional Evidence
      • produced by a specific action or event at the scene. (For example: lights, doors, windows, position of furniture, etc)
    • Indirect Evidence
      • does not prove or disprove a fact in question. (For example driving under the influence)
    • Individual Evidence
      • can be related to a single source. (For example fingerprints. Handwritings, etc)
    • Class Evidence
      • Can be associated with a group of items that share properties or characteristics. (For example: blue jeans)
    • Physical Evidence
    • The Locard Principle
      Locard's Exchange Principle states that with contact between two items, there will always be an exchange. This is the basis of trace evidence collection at a crime scene. “Every contact leaves a trace”
    • Probability and Class Evidence Activity
      Today in school, a student was seen from far vandalizing a hallway in the 3rd building. The person was wearing a black shirt, khaki pants, black shoes and had brown hair. How can we figure out who the student was or how to narrow the pool of suspects?
