Forensics is a very important part of solving crimes. There are many branches of this field. Bloodstain splatter analysis is one of the forensic sciences and is used to help figure out murders. Many things effect the blood splatter. One of which would be the surface the blood lands on. In this expirement the question “how does the surface effect the blood splatter?” will be answered. Blood splatter analysis uses biology, chemistry, mathematics and physics all to pin point the location the person was standing when they were shot and where the shooter was as well. Forensic science is any scientific field that is applied to the law of science. ("Bloodstain Pattern Analysis.") There are 5 groups within forensic science that also have more categories within them. Those being physiological sciences, social sciences, forensic criminalistics, digital forensics and other disciplines.

It can help you discover where the shooter and victim where both located; also how the gun was pointed. For example if the gun was shot straight on it would make smaller blood droplets over a widespread area. The size and how much blood varies on the force and surface. There are three angles of impact. Alpha, beta and gamma; alpha is the impact of the bloodstain path moving out from the surface. Beta is the angle of the bloodstain path pivoting about the vertical axis, and gamma is the angle of the bloodstain path measured from the true verticle of the surface. All three angles are related to the dame trigonometric equations; sin⁡〖∝ =(w/l〗)⁡and tin β= tan⁡∝/sinγ⁡ . ("Bloodstain Pattern Analysis.") The surface can effect the bloodstain because of the way it hits it. For example, tile and grass could impair the stain since they both can have irregular shapes. Concrete or woods would be best to see because the surfaces are flat and will not be

    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: Forensic Investigation

    203 Words  | 1 Pages

    Bloodstain Pattern Analysis is a forensic discipline which, among others, the position of victims can be determined at crime scenes on which blood has been shed. To determine where the blood source was, investigators use a straight-line approximation for the trajectory, ignoring effects of gravity, drag and overestimating the height of the source. We determined how accurately the location of the origin can be estimated when including gravity and drag into the trajectory reconstruction. We created eight bloodstain patterns at one meter distance from the wall. The origin’s location was determined for each pattern with: the straight-line approximation, the method includes gravity, and the method we use includes both gravity and drag. The latter

    The type of blood spatter is a transfer stain. A transfer stain is when a wet bloody surface comes in contact with another surface. Limitations of blood spatter is that it is inconsistent in reconstructing the very same blood spatter pattern. Reconstructing the blood spatter pattern is trying to mimic or imitate the pattern of the blood spatter. Other inconsistencies would be results from different people in the group would not be the same because someone could have made a mistake which means the results could vary from person to

  • Forensics in the Criminal Justice System

    The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the

  • Collecting the Evidence From a Crime Scene

    1095 Words  | 3 Pages

    Blood stains are one type of evidence that can be found at a crime scene. Blood that is still in the liquid form should be picked up on a gauze pad. Once the blood is dried thoroughly it should be refrigerated and sent to the Laboratory (Andrus et al., n.d., para. 1). If the blood stain is found dried on clothing, the officer should wrap the piece of clothing in clean paper and place it in a sealed and labeled container. An object with dried blood stains needs to be sent to the Laboratory if it is small enough. If the object is too large to send, then using a clean knife the stain needs to be scraped onto a clean piece of paper, which then can be folded and placed in an envelope (Andrus et al., n.d., para. 2). When collecting autopsy blood samples, the officer should request that the pathologist obtain the sample directly from the heart and place it in a yellow or purple stoppered vacutainer. If the victim is still alive but in serious need of a blood transfusion, then the pre-transfusion blood sample needs to be obtained promptly before the hospital discards it (Andrus et al., n.d., para. 4). It is important for the Laboratory to receive all blood samples within 48 ho...

    Forensic scientists work in labs where they examine, identify, and interpret evidence collected in crime scenes. Crime scene investigators collect evidence and pass it to a forensic scientist who uses the items in numerous ways to help catch criminals. Forensic scientists must also record the evidence and any tests run on it in detail to prove the truth in court. A forensic scientist also has to be able to present his or her physical evidence verbally in court, so a strong communication background is important. The first step taken to become a forensic scientist is to first pass the education required to become one.

  • Bloodstain Pattern Analysis

    1056 Words  | 3 Pages

    Bloodstain pattern analysis is a forensic discipline that deals with the physics of the blood, and determines the bloodstains left at crime scenes using visual pattern recognition. It is used to shed light on the reconstruction of a crime scene which includes the cause of death starting with homicide, suicide, accident, and identifying areas with high possibility of the offender leaving his or her DNA samples. There are documented descriptions of bloodstain shapes at crime scenes that date back to past centuries, but it was the Samuel Sheppard case in 1955, that prompted advances in this field. Blood­stain pattern analysis is employed worldwide by scientists, police officials and medics in an interdisciplinary manner. Both the blood itself and the surfaces on which the bloodstains are found are important in the assessment of bloodstains. The umbrella organization for bloodstain pattern analysts is the International Association of Bloodstain Pattern Analysts (IABPA), which offers various forms of membership. The name of the method (bloodstain pattern analysis) is often abbreviated to BPA.

Forensic science is a science that is applied specifically to legal matters, whether criminal or civil. “Few areas in the realm of science are as widespread and important as forensic science” (Hunter 12). Forensics is the one science that is most commonly used in everyday life. It is also a branch of science that incorporates other branches of science such as biology, chemistry, and etc. Since it is used almost every day “No one can dispute the importance of the contributions to society made by forensic science; the ability to solve crime is undeniably important” (Hunter 13).
