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
![Page 3: Ids](https://reader033.vdocuments.us/reader033/viewer/2022061618/5575ffe2d8b42a81158b4d95/html5/thumbnails/3.jpg)
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

EvidenceTime taken to obtain evidence is too fast
Normal – week even months
CSI – one day or two
![Page 11: Ids](https://reader033.vdocuments.us/reader033/viewer/2022061618/5575ffe2d8b42a81158b4d95/html5/thumbnails/11.jpg)
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

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
![Page 16: Ids](https://reader033.vdocuments.us/reader033/viewer/2022061618/5575ffe2d8b42a81158b4d95/html5/thumbnails/16.jpg)
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
![Page 18: Ids](https://reader033.vdocuments.us/reader033/viewer/2022061618/5575ffe2d8b42a81158b4d95/html5/thumbnails/18.jpg)
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
![Page 19: Ids](https://reader033.vdocuments.us/reader033/viewer/2022061618/5575ffe2d8b42a81158b4d95/html5/thumbnails/19.jpg)
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.
