Blood Spatter Analysis
1. Identifies which research methodology the authors used. The research methodology that was used was a spray on reagents to locate blood spatter that’s too small to see. Because chemicals can contaminate evidence or give false positive, an infrared camera system that exposes microscopic traced of blood without using chemicals. It is use to target blood protein which remain long after visible blood which may have been wiped away, also filtering the background infrared to revel bold residue that can’t be seen with naked eye.
2. Summarizes the research article. This article is basically about what methods used to simplify forensic process without demanding evidence at a scene. This was based off three breakthroughs where, how, and who.
Where is what investigators used to locate blood spatter and expose blood without using chemicals.
How when detectives use spatter to reconstructions to piece together what crime is may have happen. It also talks about how digital photographs of the crime scene are stitched into a panorama that shows blood-stain size and location, while the laser scanner creates a 3-D rendering of the room. The mass of each droplet is then calculated based on the size of the stain. Finally, using an algorithm developed by the Swiss team, every drop of blood has its path re-created, no string attached.
Who, Manfred Kayser and his colleagues at Erasmus MC University Medical Center Rotterdam in the Netherlands announced that they had developed a process to determine age, plus or minus nine years. The test examines white blood cells called T cells by looking for the snippets of DNA that form inside newly made T cells as they fight infections.
3. Discusses why you chose this article. I choose this article because it provides a lot of information as to what methodology is used, how it’s used and who created. In addition, the article is very detail as to what is done and the equipment that is used to properly detect evidence.
