Bloodstain pattern analysis

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. Education and training of a BPE and directionality of blood spatter, as well as its proper documentation, are some of the outcomes that will be later explained in future sections of this paper. BPE education and training Given the fact that the majority of their work is related to blood and its behavior, a bloodstain pattern expert should have a good amount of knowledge on anatomy and biology. Also, significant knowledge in areas such as physics, math and geometry are required since part of the job is to analyze the projections of the blood after it leaves the body. However, requirements vary depending on the agency. Some BPEs can be forensic technicians with advanced training while others might have medical background. Generally, a bachelor’s degree in criminology is required, but if not, the applicant must receive proper…

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…

It’s Monday, December 9th. Today just seems unusual, like something big is going to happen! I wonder what it will be for a split second, then go back to studying for the Latin America quiz we have tomorrow. Mr. Fielder announces what questions we should highlight on our worksheets. I watch him go back to his desk. I look up and out the window, I see the glistening shimmer of fresh snow dancing in the sky. I cherish every second of it, wishing the time would go by slower. As time creeps closer…

Blood Spatter: Low-velocity blood spatter would be any pattern is produced due to gravity being the only acting force (Gaensslen, Harris, & Lee, 2008, pg. 88). Medium-Velocity Blood spatter is where moderate force is applied from objects which can cause pooled blood to scatter in multiple directions surrounding the contact (Gaensslen, Harris, & Lee, 2008, pg. 89). “High-velocity blood spatter is the where extreme force acting on the blood source (Gaensslen, Harris, & Lee, 2008, pg. 89)." Blood…

Forensic Functioning In America the word forensics proposes crime in a way that excites stories on serial killers, murder, crime scene investigation, and heavy DNA analysis. In reality, this only breaks the ice on what forensic science fully consists of. Forensic science is initially any science used for the purpose of law. The evidence tested is used in the court of law, criminal investigation, and trial. A forensic scientist does perform tests on blood and bodily fluid as well as…

behind his head is tainted with blood in an identical manner as the smiley face symbol. This blood is of two innocent children both killed by their father. Nowhere does religion approve of bloodshed especially of children by their own father. Maybe before the murder, the family was happy or was pretending to be happy, but ultimately, the father’s immoral act can’t be overlooked regardless of the situation the family was in prior to the murder. Another manifestation of the symbol is on page 14…

whenever a gun is fired, microscopic characteristics or imperfections are transferred through the gun barrel to the bullet and cartridge casings in the form of scrapes, grooves, scratches, marks or indentations.” (Keyserlingk, 2003, para. 3).The body was to be observed for other marking such as cuts or bruises to help with determining whether or not the victim was able to put up a fight that would determine if the cut or bruise are defensive wounds, or was the victim caught off guard, also…

Through Sociology, not only can we study human social behavior, but we can also aim to analyze the behavior through certain concepts. With the help of media we are able to demonstrate these concepts to give us a more in-depth view of how they function. Both television shows and movies can be great for giving us the illustrations we need to understand an idea. Over the course of the essay, Dexter will be used as a model for some of the ideas focused on in Sociology. Through the concept of…

enforcement personnels, medical examiners and criminologist to find the physical evidence and to understand the events that surrounds the occurrence of a crime. If there is a bloodstains then the location and the distribution of the blood stain along with the spatters maybe useful in explaining the events that caused the bleeding. An investigator can decipher from an individual bloodstain, the direction of blood, when it impacted the surface it was deposited on. Bloodstain patterns, consisting…
