The Bloodstain Patterns

When I stepped into the core lab, the Hematologist Melissa showed me around the lab. There were many machines such as sysmex xe-5000 that help the hematologist in detecting singularities in the blood. The machine that I mentioned above scans the barcode from the tube, turns the tube up and down to mix WBC, RBC, and palate, and takes in little samples of blood to determine whether the owner of the blood have any unusualness in their blood. Sometimes, she would do manually in order to find the number of the palate; she would insert blood

From the start of independence, the question of the process of career selection has stumbled teens across the globe. Whether the outcome be based on the amount of money, the location, or even the very few who find their true passion, no one has a definitive idea on what they will pursue. Richard Van Camp’s main character, Leo, is faced with the same dilemma. Van Camp's short story, “The Strongest Blood”, explores the use of symbolism, brought through by money, the conflicts in which influence career decision, and the use of pathos to evoke an emotional connection to the reality of the world.

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 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.

The goal of this experiment is to determine the blood types of the samples given and to learn what interactions occurred to each blood type. Determining an individual’s blood type and how it reacts with Anti A, Anti-B, and Anti Rh serums played a crucial part in this experiment. The researcher concluded that agglutination (clumping) occurred in some of the blood samples. For example, Mr. Smith’s blood reacted with Anti-A and Anti-Rh serums (antibodies) allowing the researcher to determine the blood type is A. Mr. Jones’s blood reacted with Anti-B serum but it did not react to Anti-A or Anti Rh allowing the researcher to believe that the blood type is B. Mr. Green’s blood reacted with all serums and caused a reaction to occur resulting the blood type to be AB positive. Mr. Green’s blood also had a positive marker for Rh factor. However, Ms. Brown’s blood had no reaction at all and the researcher determined if no reaction occurred then the sample had no antigens but proved to have some antibodies, resulting in blood type to be O. The purpose of this experiment is to determine whose blood has type A, B, AB, or O.

For this experiment student will identify the individual blood types through the antigen and antibody reaction by using the anti- A, Anti- B and Anti- Rh serums we will be able to identify the different types of blood. Red blood cells also known as erythrocyte are small cells shaped like an oval however they have a plasma membrane but no nucleus. Hemoglobin is the protein that allows the red blood cells to bind easily with oxygen. While hematopoiesis is known as blood cell formation. The independent variable would be the Red blood cells. While the dependent variable would be the Antibodies and the antigens

The blood samples were put with Anti-A serum and Anti-B serum. The blood found at the scene clumped with Anti-B serum but not with Anti-A serum. Anna Garcia’s blood clumped with Anti-B and not with Anti-A serum. This means that Anna’s and the blood found found at the scene had Type-B blood. Alex Garcia’s blood sample clumped with Anti-B and and not with Anti-A, just like Anna Garcia’s and the blood from the scene.

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

The blood at the crime scene could have belonged to either Anna or Erica because they both have type A blood. The fingerprint belonged to Alex Garcia who had a radial loop. The unknown substance found at the crime scene tested positive for acetylsalicylic acid (aspirin). Two types of drugs that were found on Anna including novolog and lantus.

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.

The wet blood should be transferred onto clean cotton cloth. Bloodstained cotton cloth must be allowed to air dry before packaging in a paper container. Each object and container must be properly labeled. Dried bloodstains on weapons, for example, should be collected separately by collecting the entire item. Each item should be placed in its own paper container, and these should be sealed and labeled properly. The bloodstain pattern should be documented and sketched to the extent necessary. The stain can be tape lifted or scraped off the object onto a clean piece of paper. The tape lifter or the paper with blood can then be placed into a druggist fold, and placed in an envelope which is sealed. Each item must be labeled

It was determined that both Sam and Marilyn Sheppard were grouped to have Type A blood but two spots that were found were not Type A. The first spot which was the largest blood spot in the bedroom was found on the closet door near Marilyn’s bed. The second spot of blood was on the knee of Sam Sheppard’s trouser pants. Both spots of blood were examined and determined that they were Type O blood. Dr. Kirk in court testified that the blood that was found on the closet door did not belong to either Sam or

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

To determine the nature of the ink sample, we used paper chromatography to separate and examine the various pigmented chemicals in each possible type of marker. After careful cross-examination, we determined that ink sample B (the ink found at the crime scene) matched the ink sample of the Vis-à-vis marker. Both ink samples displayed a range of pigmentation from light to dark grey, with a bright blue rim on the ethyl alcohol chromatography test and a yellow-pink-magenta-purple-blue progression on the water chromatography test.

belonging and family, whereas in the outside world they were seen as enemies. As a result, it becomes apparent that minorities from different backgrounds face similar difficulties when trying to assimilate into the American culture. It is through these difficulties that they begin to develop feelings of loneliness, and what can potentially motivate them to go down a path of delinquency, as it is a lot easier than having to face the challenges of trying to adapt to a different culture.
