Murder Most FoulDone 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 DNA

Worked: 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 principleWhere 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

Misconception

Results are usually not as clear

Finger print , DNA

EvidenceComparison CSI vs. Real life

EvidenceTime taken to obtain evidence is too fast

Normal – week even months

CSI – one day or two

Using fingerprints as evidence8 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 classificationLip length size

Broadness of lips

Grooves on lips Vertical grooves Partial grooves Branched grooves Intersecting grooves Reticular grooves

VerdictPunishment 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 crimePeter 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

Charged Reasons

Peter Hamilton – Murder

Jack Smith – Manslaughter

Peter had masterminded the murder and influenced/pressured Jack to carry out the killing.

Jack Smith was probably under pressure by Peter to kill John. As such, provocation is evident and the guilty is therefore charged with manslaughter and not murder.

Your selection - reflectionFinger 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.

ReflectionsAlex: 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.
