Of Bloodstain Patterns Function of bloodstain pattern analysis Bloodstain pattern interpretation/analysis has been around for many years but has only really been recognized in the past several decades. This interpretation/analysis is like a very important tool that an investigator or forensic scientist may use to help them better understand what happened or what did not happen in a case where there was bloodshed. Discoverable through the examination of bloodstain pattern The

passive patterns or projected patterns. Blood splatter analysis becomes important when recreating a crime scene (Peschel). Bloodstain pattern analysis comes into play; and that is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed (“A Simplified Guide”).

Convergence is a point where the width and length on a plane from which the drops of blood stain was from. Area of Origin is an impact pattern of bloodstain where the height‚ width‚ and depth created. Both origin of impact pattern help

Whorls only 30 to 35% of people have this particular print ‚ and arches and only about 5% have this particular fingerprint. 2. What is a medulla? What do forensic scientists use this for? it cells that run through the hair. they use it for showing if chemicals have been in the hair such as bleaching or dying and to look

Introduction: Bloodstain spatter pattern analysis is one of several specialities in forensic science. The analysis of the blood droplets upon contact with a surface is used to create a three dimensional space symbolizing the area of convergence of all the stains‚ this method is used to find the source of the blood. The source of the blood helps forensic analysts to understand the crime scene better and thus have an understanding of where the incident took place. A blood

Blood Splatter Analysis Criminology – Gregory S. Webb Professor David Geddings Trident Technical College Abstract Blood splatter analysis is an important combination of different forms of forensic science. Using a combination of chemistry‚ math‚ physics‚ and biology blood splatter analysts can predict certain patterns such as: splatter flight characteristics‚ angles of impact‚ point and area of convergence‚ area of origin‚ and many other patterns that can lead to a very strong and persuasive

Due to the lack of information associated with the crime scene and information on the length‚ width and depth of the bloodstains it was very difficult to analyze. I think I may have figured out what happened. The victim Ms
