  • 1. Murder most foul
    Done by: Group 16
    Lim Jingkai(15)
    Dickson Lim(14)
  • 2. Introduction
    Solving the crime
    The Verdict
  • 3. Solving the crime
    Most difficult task: To find a link from the various evidences
    Easiest task: The lab work where the evidences were identified and analyzed
    Task Worked: Looking from different perspectives and identifying reliable statements
    Did not work: Questioning the same suspects
    Suspects would lie and not tell the truth.
    The leads would get us nowhere.
  • 4. Media
    The media: Aims
    To earn profits
    To be the first to publish
    Increase profits (Sensationalize stories)
    Readers like to read exciting news
    Interest/attract readers
    Fabricate facts
    Media Source:
    Not helpful
    Misleading information (Lead us off-track)
  • 5. What we learnt
    Able to identify false and true testimonies
    Able to find links based on evidence
    Able to find flaws in information
    Able to source out useful information from others
  • 6. Fingerprints
    Fingerprints look similar to the naked eye
    It would be more accurate if more matches can be found
    Avoid prosecuting the wrong person and letting the guilty escaping
    8 matches are required to be submitted as evidence
  • 7. CSI
    Dramatic forensic science
    According to CSI, evidence is perfect and easily identifiable
    In reality, according to Locard’s Principle, evidence is contaminated and may even contain traces of people who have no link to the crime but have been in contact with it
  • 8. CSI
    It aims to attract viewers to the show to increase profits
    Does not showcase authentic forensic science such as the procedure and tools
    CSI cannot be trusted completely
    CSI movies only require a few fingerprints to prove the suspect guilty but however, in the real case, investigators require 8 matches in Australia to prove guilty.
  • 9. Lip Print Classification System
    Classification system for lip print is similar to a fingerprint’s
    Able to identify corresponding points on lips
    Such as forks line and vertical lines
    Must have a minimum number of matches
  • 10. Proving and Knowing
    Difference: Proving requires evidence
    Example: We knew that Jack Smith was the murderer
    Needed evidence such as DNA matches in order to prove him guilty
    Peter Hamilton was alleged to be at the crime scene
    But needed concrete evidence to prove.
  • 11. The Verdict
    Jack Smith
    Peter Hamilton
    Robyn Jones
    Jane Liu

    Assisting in the crime

    Accused of murder of John Lee.
    Fingerprint found on cartridge
    Confession of Robyn: Jack was at the crime scene.
    Janet Perry witnessed Jack with Peter.
    Blood found at evidence F04 belonged to Jack
    He should not be treated leniently as it is a deliberate act (planned)
  • 13. The Verdict
    Peter Hamilton
    Providing firearms to Jack for committing murder
    Assisted Jack in the crime
    Making false statements
    DNA found in footprints on garden bed
    Witness statement:
    John was on bad terms with Peter.
    Had an argument with John before crime was committed at Robert Isles’s house.
    He should not be treated leniently as it is a deliberate act (planned)
  • 14. The Verdict
    Robyn Jones
    Crime: False statements, Drugs
    Hair was found
    DNA on cup was found
    Tests showed under alcohol influence.

  • 15. The Verdict
    Jane Liu
    Crime: False statements
    Confessed to being at crime scene
    Gave false statements to police
  • 16. Reconstructed
    Death of John Lee
    Due to several reasons
    Failure to pay up $5000 debt to Peter.
    Possibly due to drug dealings.
    Resulted in argument at party
    Peter asked Jack Smith along with him
    Robyn was with John, provided the location of John
    Peter and Jack went to Classroom
    Jack murdered John.

  • 18. The Verdict
    If I were the judge, I would have felt that the suspects are guilty.
    There were sufficient evidence to prove that they were at the scene when the murder happened
    However, there was not sufficient evidence of Jane or Robyn providing assistance to the crime.
