Blood Pattern Analysis

The popular television show, CSI: Crime Scene Investigations has been on the air for 12 years, and it has brought forth the behind-the-scenes actions of criminal investigations, even if its portrayals are not always scientifically accurate. This has caused an interest in the forensic sciences that has led most people to a skewed view of how a criminal investigation actually works. The reality of a criminal investigation is that it is generally more tedious and difficult than the theory of criminal investigation would have you believe. By examining the forensic and investigative procedures of the case of Pamela Foddrill, it is apparent that the theory of criminal investigation was not representative of the procedures concerning examination

In this position paper I have chosen Bloodsworth v. State ~ 76 Md.App. 23, 543 A.2d 382 case to discuss on whether or not the forensic evidence that was submitted for this case should have been admissible or not. To understand whether or not the evidence should be admissible or not we first have to know what the case is about.

Forensic science and law are often seen as two opposing disciplines; forensic science is often presumed to be factual and law can be interpreted in multiple ways. Science and law reach conclusions in different ways which is an issue. Due to these differences, miscommunication is often the cause for miscarriages of justice. In order to address this problem, people working in the criminal justice system should have more knowledge of forensic science. There are many factors that contribute to the lack of understanding between forensic science and the people involved in the court process. Firstly, the adversarial model will be discussed in relation to how these procedures prevent effective communication between forensic evidence and lawyers. Secondly, the role that expert witnesses play in the presentation of scientific evidence and how jurors play a role in interpreting their evidence, will be considered. Thirdly it will be argued that lawyers and judges lack adequate knowledge of forensic science that is needed to conduct accurate trials. Lastly, possible solutions to improve the communication between forensic science and the actors involved in the criminal justice system. Juries, lawyers and judges should be more educated in understanding forensic science.

Identity that which we all struggle to find. Miklo is the very same case in Taylor Hackford’s Blood In Blood Out who struggles to prove himself as a Chicano due to his white skin however culturally Miklo is as Chicano as anyone in Onda. The most important part of this dynamic, is that when Miklo gets arrested for killing spider, a rival gang leader, the prison gang system is divided by race and skin color all which he is stuck in the middle of. In prison, is where he would meet Magic a member of spider’s gang which openly fought with Miklo’s gang Vatos Locos. They quickly become friends despite their previous conflicts and confrontations between the two gangs because as Popeye mentioned everything is determined by race. This is relevant as in

The world of Forensic Scientist is an amazing and fascinating place. There are so many aspects that go into forensic science but in this paper we are only covering bloodstain spatter patterns. Bloodstain spatter patterns are not solely used to solve crimes but I do feel it is one of the most important. Bloodstains never lie.

It is important for a forensic scientist to determine the distance from a gun to a shooter because in some cases a

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 after bloodshed began, position of objects at the crime scene and the type of weapon, if any, that was used can be uncovered.

While on scene I observed blood droplets in the kitchen, dining room, Living room, laundry room and a long hallway leading into the residence from the backyard. Once outside of the residence I observed further evidence of a physical confrontation, including additional blood spatter and droplets scattered throughout the yard near a burning fire where it appeared, due to multiple empty alcoholic beverage containers the subjects had been drinking.

Blood spatter analysts are a crucial part of a homicide investigation. They examine the blood stains left behind at a crime scene with the help of criminal investigators. They try to find a pattern or trail with the blood to figure out what happened at the crime scene. These blood patterns can show where the victim was hit, how they were hit, if they struggled, and what kind of weapon the killer used. They use many techniques to collect evidence that can be analyzed at the lab. Common techniques are measuring the diameter of the blood drop, measuring the spatter zone, and taking pictures. Many analysts try to act out the homicide scene to piece together the crime scene and figure out what happened. They also sketch out the scene to go along

he Blood Spatter Analyst (also known as "Bloodstain Pattern Analyst") uses many techniques to collect and analze blood that has been left behind at a crime scene. They uses swabs and ultraviolet light, as well as photgraphy to collect and analyze trace evidence and recreate spatters. After analyzation of the spatter, they can determine what weapon was used, which direction the suspect or victim went, the number of wounds the victim suffered, the trajectry of a projectile, and what occured during a violent crime.

There were two pieces of evidence that came into question with regards to blood spatter. In the 1956 trial Gerber, the coroner, claimed that an outline in blood on one of the pillows resembled that of a surgical tool but was unable to identify the surgical tool. Gerber would have concluded this observation by believing the bloodstain pattern was a transfer pattern. It was concluded however, that the result of the blood stain on the pillow came from another pillow overlapping it.

In this video Correspondent LOWELL BERGMAN questions the scientific validity of forensic science. He also expresses that it is not as simple as it appears on television shows. Detective. Joanna Grivetti who is a crime scene investigator in Richmond, California explains that the real life CSI is getting dirty, smelling things you don’t want to smell, seeing things you don’t want to see and dealing with blood in order to collect evidence that may seem small at the time, but will ultimately (possibly) be a big deal in solving the case.

Bloodstain pattern analysis (BPA), known in the criminal justice field as blood splatter analysis, has been studied since the 1890s. Blood splatter, or bloodstain pattern constructional readings, is a technique that seeks to piece together the incident that caused an individual’s bleeding. Understanding blood splatter on a wall or various surfaces can be instrumental in formulating if a crime was committed and if the blood discovered at the crime scene can be used as evidence. The first documentation of blood splatter research occurred at the Institute for Forensic Medicine in Poland, by Dr. Eduard Piotrowski . During Dr. Piotrowski’s research and documentation period, where he used live bunnies to research blood splatter from head

Have you ever wondered how much a single blood splatter could impact a whole crime scene? In January 2004, Sachs and Jessica Snyder wrote an article titled, Blood is the Ink, Crime is the Story, which could be found in “Popular Science”. Blood spatter tells more of a story than most individuals know, including detectives and crime-scene analysis. A blood stained analysts, Paulette Sutton, informs those who do investigate crime how important a single blood stain is. An average everyday person could easily tell which direction the blood stain came from, and what height it had fallen from, nevertheless there is still more to the story.

Forensic science is a key aspect of Criminal Justice that helps rid the streets of lunatics and murderers. One of the most important fields of forensic science is blood spatter analysis. Under the Crime Scene Investigation, analysts gather the information that could eventually lead to a victim’s killer. Basic and complex information can be found when analyzing blood. We can learn what kind of weapon was used, the time of death of a victim and other important facts that can help a case. The pattern that the blood gives off give forensic scientists the tools that they need to help solve cases.
