Forensic scientists apply scientific procedures and techniques to the examination of potential evidence that may assist in legal investigations.
Forensic scientists may perform the following tasks:
- identify illicit drugs
- analyse drugs and poisons in human tissue and body fluids, including blood alcohol results
- examine and compare materials such as fibres, paints, cosmetics, oils, fuels, plastics, glass, metals, soils and gunshot residues
- examine human and animal biological material to be compared with victims and suspects using DNA profiling
- conduct botanical identification of plant materials at trace levels and whole-plant identification (e.g. cannabis)
- conduct document examinations, both physical (e.g. handwriting, typewriting) and chemical (e.g. analysis of inks and papers)
- analyse computers and obtain data from electronic devices
- examine crime scenes
- identify firearms and ammunition (forensic ballistics)
- detect, enhance, recover and identify latent fingerprints, footprints, tool marks, shoe marks, tyre marks and tracks
- examine fire and explosion scenes to establish the origin and cause
- improve the clarity of, and analyse, audio and video recordings
- produce reports, appear in court and present scientific and/or opinion testimony accurately and in a manner which is readily understood by the court
- make presentations to a wide variety of audiences on the work of forensic scientists
- keep in contact with, and provide advice to, police investigators, legal practitioners, scientists and pathologists across a broad range of disciplines.

What are angles of
impact?Angles of impact is where blood hits and then moves the rest of the way according to gravity. Blood that does not land on a 90degree surface will hit at an angle. Once the blood hits something at an angle it will start to drip according to gravity. This can help to determine the point of origin of the blood splatter. The length of the blood stain is the hypotenuse while the width is the opposite side of the angle of impact. The angle of impact can be calculated from the measurement of the opposite side which is the width and the length is hypotenuse of the blood stain.
Blood stain categories :
There are three main categories that bloodstain patterns fall in. They are:
-Passive Bloodstains: These are formed by the force of gravity. It can be further divided into:
-Drops: This is formed by gravity alone. It has no other influences.
-Drip patterns: This is formed when blood drips into blood; it forms a new pattern.
-Pools: This is when the blood drip stay stationary for a long period of time.
