FSC239Y5 Lecture Notes - Lecture 2: Surface Tension, Sam Sheppard, Size Small
Document Summary
The study of the shape, size, distribution and location of bloodstains. Provides info about the events that created the bloodstains and patterns. Bpa tells us about the how as opposed to the who. Bpa is one piece of a multi discipline investigation: other physical evidence (fingerprints, dna analysis, witness statements, forensic pathology, electronic evidence (ie. video recordings) Liquid blood will behave according to the laws of physics. Formation and appearance of bloodstain pattern is surface dependent. Movement of ppl and objects during bloodshed. Movement of ppl and objects after blood shed.
