Blood spatter analysis is very important in crime scene investigations. Documentimg it quickly and properly when you arrive at a scene can help investigators possibly know what type of weapon was used, was there a lot of force used in tha crime and the direction and angle of the blood spatter can help recreat the events that took place at the scene. Once the blood spatter is documented and photographed as accurately as possibly, it will help the lab figure out what possibly happened leading up to the event. Alos, getting accurate measurements and pictures of the blood spatter may even take the blame off of someone wrongly accused in that crime.
The understanding of blood spatter patterns is not a widely recognized forensic practice. Bloodstain pattern interpretation (BPI) is commonly used in murder investigations, but could be utilized in everything from simple assault to mass murders if the number of trained professionals increased. BPI can reveal critical information into reinventing a given crime scene. Everything from the number of blows, stabs or shots a victim was given, the movement that was undergone by the victim and assailant….

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….
Crime Scene Investigation

These patterns include line/strip search (used by one or two investigators who walk in straight lines across the crime scene) this method is best used in scenes where the boundaries are….
