FSC239Y5 Study Guide - Comprehensive Final Exam Guide - Dna Profiling, Coroner, Autopsy
Document Summary
Locard"s principle: every contact leaves a trace, suspect will leave something at the scene, suspect will take something away. What evidence do we look for: fingerprints: impressions from the friction ridges on our fingers, they are reliable and persistent (remain the same). They are formed during the second trimester of pregnancy and do not change until decomposition after death: they are unique. Next you photograph the fingerprints (in case you mess up lifting with tape and also to prove to the court that you found the fingerprint, where it was found, etc). Steps to follow: once entering the scene, bring flashlight and examine any foot prints with the oblique light (essential). Try not to walk around and contaminate the scene with your footprints (contain): when you take photos and notes of everything you can always go back knowing where, when, etc, walk through access.
