    • Murder Most Foul
      Done by : Group 23
    • Solving the crime
      Most difficult task:
      Knowing what happened in the room
      Suspects unwilling to answer
      Making sure evidence was accurate
      Almost no eye witness
      Evidence is fake
    • Solving the crime
      Easiest task:
      Lab lessons
      Structured and clear
      Material provided
      100% results obtainable
      Results were satisfactory
    • Solving the crime
      Did not work:
      Extracting information from specific interviewees (Peter Hamilton, school cleaner, etc.)
      Worked in part:
      Inferring from data (suspects )
      Inferring from evidence collected
      Questioning the eye witness (Janet Perry, etc)
      Obtaining evidence
    • Solving the crime - Media
      Provide sensational news
      Make news interesting
      Many assumptions made
      Evidence fake or not well supported
      Irrelevant information (Mr. Lake)
    • Evidence
      Long and tedious process
      Require substantiated evidence
      If time take too long, evidence is lost
    • Locard’s principle
      Where everyone that comes in contact with an environment leaves a trace
      F03 & F05 – DNA belongs to John Lee
      F04 – DNA belongs to Jack Smith
      F12 & F28 - Belongs to Robyn Jones
      Footprints, paint chip and handwriting belong to Peter Hamilton
    • Evidence – CSI vs. Real Life
      Not realistic enough
      Results are usually not as clear
      Finger print , DNA
    • Evidence
      Comparison CSI vs. Real life
    • Evidence
      Time taken to obtain evidence is too fast
      Normal – week even months
      CSI – one day or two
    • Using fingerprints as evidence
      8 fingerprints must match
      Fingerprints may seem similar
      May belong to different people
      Must match more fingerprints to confirm evidence
      Fingerprints also might be damaged/unclear
      Will not arrest the wrong suspect
Lip print classification
      Lip length size
      Broadness of lips
      Grooves on lips
      Vertical grooves
      Partial grooves
      Branched grooves
      Intersecting grooves
      Reticular grooves
    • Verdict
      Punishment given to:
      Jack Smith
      Murder of John Lee
      Peter Hamilton
      Intended murder
      Dealing of drugs
    • Severity of Punishment
      Jack Smith – Lifetime imprisonment
      Murdered John Lee
      Peter Hamilton – Lifetime imprisonment
      Peter Hamilton’s idea to kill John Lee
      Mastermind of murder
      Repeat offender
    • Theory of crime
      John Lee bought drugs from Peter Hamilton
      Unable to pay $5000 to Peter Hamilton (Coded note)
      Handwriting on note matched Peter Hamilton (Showed that Peter Hamilton linked to John Lee)
      Resulted in a dispute in Robert Isle’s party
      John Lee, Jane Liu and Robyn Jones left for the school at 3.15pm
      Followed by Peter Hamilton and his accomplice Jack Smith 10mins later
    • Theory of crime
      John Lee, Jane Liu and entered the classroom
      Cup Lip print, Vodka Bottle, Beanbag DNA match Robyn Jones
      Followed by Peter Hamilton and Jack Smith
      Peter Hamilton’s footprint found at garden (F02)
      Evident that Peter Hamilton entered because he was a painter and had left the paint chip
      When Peter Hamilton came, Jane Liu and Robyn Jones left because they were afraid
    • Theory of crime
      Peter Hamilton then demanded money from John Lee
      John Lee refused
      Jack Smith instructed to deal with John Lee
      Resulted in fighting and John used a window shard to cut Jack
      Blood on wall matched Jack Smith
    • Theory of crime
      Jack Smith then back away
      Shot John Lee (Height of Jack Smith’s outstretched arm is 145cm)
      Bullet entered and exited body at 145cm
      Evidence then moved (Bullet Cartridge)
      Fingerprint on bullet cartridge matched Jack Smith
      Left with Peter Hamilton
    • Verdict – If I were a judge
    • Your selection - reflection
      Finger printing
      Effective tool in solving crimes
      However is a long and tedious task
      Requires fingerprints of as many people as possible to be really effective
      Therefore, third world countries may have trouble with solving crimes with fingerprints
    • Reflections
      Wallace : I feel that this course has been an extremely enriching one. I have learnt much in the duration of the course. My team mates and I had several disagreements but ultimately, we got through. I feel that we have come a long way since the first day of the course, where we had no idea of where we were heading, what we were doing, and even why were we there. I was suffering from constant fatigue during the course. Much work had to be done on an extremely tight schedule. Nevertheless, my team mates and I had acquired a sense of accomplishment at the end of the day- it paid off. I hope that I will have the chance to attend another similar course in the near future.
    • Reflections
      Alex: I have learnt a very important lesson through this sabbatical. Through questioning we can tell that we, students of Singapore, are quite useless when it comes to something not in our textbooks. I have learnt to broaden my knowledge so that this knowledge can be used for all purposes and not just for structured examinations. This is the biggest take back from this sabbatical as this is a skill that many of us lack and is very vital for us to think critically in the future.
