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
To record a crime scene, forensic scientist can use photography, drawings, and videography. Photographs are an important record of the unaltered crime scene, Drawings or sketches provides valuable information when a photograph cannot accurately depict the scale of a room or the relationship of items to each
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
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.
crime scene could be analyzed and compared with a sample from a suspect. A match could place
On the morning of September 2, 2003, Sarah Johnson, at age sixteen, shot and killed both her parents, Diane and Alan Scott Johnson. This crime occurred in Bellevue, Idaho, in the Johnson’s home with a Winchester rifle. At approximately 6:20 am, Sarah came into her parents bedroom and shot her mother in the head through the blankets, killing her. Next, Sarah moved into the master bathroom and shot her father. Investigators believe that Alan Scott Johnson, Sarah’s father, was emerging out of the shower when he was first shot.
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.
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
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.
In this day and age law enforcement agencies use many different types of technology in order to help combat and fight crime. Because technology is forever changing this means law enforcement officials need to stay up to date with the latest technology. I wanted to go over technology that is available to police officers, prison guards, and probation officers. One of the many technologies available to police officers are fingerprint technology which provides him the opportunity to successfully lift prints throughout a crime scene. Once these prints are lifted they will go through the proper chain of custody and be processed by the officers local or state lab to see if there is a match. Another form of technology is if blood is found at the crime, any type of blood that is found at the crime scene of course it would be swabbed, for anything that is collected you would also need to
One of the most important purposes of physical evidence is to establish the identity of a suspect or victim. Some of the most valuable clues at a crime scene are fingerprints. "Processing a crime scene" is a long, tedious process that involves focused documentation of the conditions at the scene and the collection of any physical evidence that could possibly shed light on what happened and point to who did it.
Given that blood spatter analysis is an emergent field, with rapidly occurring developments have significant probative implications for the court system, this project will seek to examine the multi-faceted elements of blood spatter analysis to provide an overview of the field’s different dimensions. Focusing on technical developments, analytical interpretation and court relevance, the project will propose that blood spatter’s analysis as a mainstream element of the CSI toolkit results from the combination of physical sciences and analytical rigor which lies at its core. Beginning with questions of technical and physical science, the project will
Bloodstain pattern is the most important evidence at the crime scene (Saferstein, 2011). Blood stains pattern can be evaluate by serology and answer a number of questions (Saferstein, 2011). For examples, the mark of origin of the blood, distance of the blood sprinkle or how far away of the origin, how many gunshots were fired, the direction of travel by victim or suspect, position of the victim and suspect during bloodshed, repositioning of objects or bodies after the bloodshed, whether a person was moved while shedding blood and order of the events happen during the crime (Saferstein, 2011).Bloodstain sample of any type can give a lot of data about the occasion that occurred at crime
After doing their job in he crime scene, the evidence they took will be taken to the forensic scientist. Crime scene investigators will look at the photographs and connect their theories based on the crime that occurred. The forensic scientists will also examine the victim’s clothes, while the medical examiner will analyze the victim’s body for more clues and evidence that they may find and they will all be doing this in the crime lab. The things they may find could be hair, fiber, semen, blood, another person’s DNA, bruises and many more. After the forensic scientists
The photographer that is present at the crime scene is responsible for making one picture worth a thousand words. Photography plays an integral role in the documentation of physical evidence found at crime and accident scenes as well as during forensic autopsies. Forensic Photographers are among the first crime scene technicians to arrive at crime and accident scenes. They walk through a scene to obtain an overview before they begin taking photographs. Forensic Photographers apply their technical skills and their knowledge of anatomy and forensic requirements to take photographs that convey the information that crime scene, criminal, medico legal, or forensic investigators need documented. These
Forensic science involves the use of science to solve criminal and civil crimes but mostly lies on the side of criminal investigations. It makes it possible to identify the criminals based on the DNA traces they leave behind. It involves analyses of blood, DNA and other evidences and later on uses the findings as evidence in the court of law. It helps in solving the various crimes in the world and this has been the greatest contributor to the growth of the sector. Cases that were previously considered impossible due to lack of evidenced tracing to the victim can now be solved using forensic science evidences. The essay aims at analyzing the different aspects of forensic science that are used in the process of solving criminal activities. It will also look at the different cases that forensic science was used to solve crimes in a court of law.
