Bloodstain pattern analysis

According to Bevel, T and Gardner, R.M (2008), ‘bloodstain pattern analysis seeks to define the facts surrounding some incident that is in question. The examination of the physical nature of bloodstains provides information specific to the events that occurred during the incident’. Analysts can examine the shape, size, location and distribution of the bloodstains to form their own opinions about what did or did not happen. BPA uses mathematics (geometry, angle and distance); biology (behavior of blood) and physics (capillary actions, velocity and cohesion) to assist investigators in answering the questions needed to solve the…

that can tell a story is bloodstains. The highly adroit workers that read that story are called bloodstain experts and or analysts (Crime Scene Investigator, 2000-2014). The analyst’s number one job is to amass hard physical evidence from malefaction scenes (Roufa, 2014). After amassing all of their evidence, they put them in two categories like spatter patterns, transfers, voids and many others (Crime Scene, 2014). Additionally, to be an expert one must ken all the blood patters. A bloodstain…

Sutton, 2005 p. 1). A Bloodstain Pattern Analysis is called when bloodstains are found at a violent crime scene. The Bloodstain Pattern Analysis discipline has been in existence for a long time, as early as the late 1800’s. “Bloodstain Pattern Analysis focuses on the analysis of the size, shape, and distribution of bloodstains resulting from bloodshed events as a means of determining the types of activities and mechanisms that produced them” (James, Kish, and Sutton, 2005 p. 1). The…

A Bloodstain Pattern Expert (BPE) sustains the job of formulating a theory as to what happened on the crime scene and answering questions about it. In order to do this, the BPE relies on a type of forensic science called Bloodstain Pattern Analysis (BPA) that helps obtaining DNA testing, autopsy results, bullet trajectory, and other relevant information to the case. The purpose of this paper is to explain and direct the reader into a better understanding of what this area of forensic deals with.…

Bloodstain Pattern Analysis also known as BPA is defined as the diameter and shape of blood splatters, which reflects the origin and trajectory of external blood flow in the context of homicide or violent death, in which the skin surface is disrupted (Medical dictionary https://medical-dictionary.thefreedictionary.com/Bloodstain+Pattern ). The development of bloodstain pattern analysis dates back to nearly 150 years ago in history and through the years there have been many studies, developments,…

Bloodstain Pattern Analysis “What processes must be undertaken to analyse bloodstain patterns at a crime scene for the purpose of presenting this evidence at a criminal trial under South Australian law?” Blood. Sticky, hot, messy, awful blood. For most of us, the sight of it turns the stomach, but in the court of law, blood can tell a lot more about a crime scene than you might think. Forensic bloodstain pattern analysis (BPA) is the interpretation of bloodstains for the purpose of…

Focusing specifically on forensic law, the first thing i'm going to talk about is blood splatter. According to crime scene investigator. “Because blood behaves according to certain scientific principles, trained bloodstain pattern analysts can examine the blood evidence left behind at a crime scene and draw conclusions as to how the blood may have been shed.” If you want to know what blood spatter is, it is a bloodstain pattern resulting from blood drops that traveled in the same direction as…

A tremendous amount of education is necessary for one to be an efficient bloodstain expert (BPE). Experience in this field is also a great tool when it comes to making the correct judgment. Experience helps an expert to determine the bloodstains that may overlap. A single crime scene may have various bloodstains patterns. This leads to the need of a BPE though it is very important to weigh in all the evidence at the scene. Some evidence includes bullet trajectories, DNA, firearms analysis (if…

average person thinks of blood, we consider the typical concept that blood keeps the heart beating, the body functioning. For others, blood is much more than a simple liquid; it’s the only thing they may have to catch a murderer. But, is it the most reliable option? Through looking into a detective’s point of view, we will analyze how the size, shape, and splatter of blood, the color of blood, and the deterioration of blood can help detectives solve a case. While it may not be the most effective…

another crime that eventually lead them getting caught as a serial killer and lastly they were turned in by someone who knew offender which discus the serial killer telling someone about who they are and that person decides to turn them in. After the study, researchers concluded that many of the serial killers were caught using several methods and not forensic science alone. Another method for capturing the serial killers is by media and publicity. When law enforcement informs the media of the…
