Blood Spatter in Crime Scene Investigation Essay Example for Free

Blood Spatter in Crime Scene Investigation Essay Checking all aspects of a crime scene is a crucial part of investigating a crime. The thorough sampling of all suspicious items in a crime scene, like footsteps, hair strands, and even the changes that took place in the pieces of furniture may help in leading the authorities to the doer of the crime. Oftentimes, even the way the blood splattered from the victim to the walls and floors of the crime scene can help pave the way to the solution of the crime. Blood may be like any other piece of evidence in a crime scene. It is what everyone else immediately sees. It does not talk, yet it can tell so much information. Through analysis of blood splatter, an investigator can tell how the person was killed and from what angle it was done. It can also tell whether the act done fast or as slowly as possible. Blood splatter can greatly help in crime investigation through the analysis of it. Human Blood Normally, the human blood comprises seven to eight percent of the body weight. It carries the essential functions of carrying oxygen and nutrients to the body cells. It also rids the body of carbon dioxide, ammonia, and other body wastes. The blood also serves an important role in the body’s immune system and in maintenance of the body temperature. It is a specialized tissue that has various components. It is a four to six quarts tissue with many components being pumped throughout the body. It circulates constantly in the body, making everything function normally. This is the reason why, when this circulation is disrupted by any action, it spatters (O ‘Neil, 2008). There are various ways that can greatly disrupt the circulation of the blood. Definitely, the most disturbing are violent confrontations like, bullet-shot trauma, blunt force trauma, or knife trauma. The effects of these acts on the blood may vary into two. It can either spill or the blood may spurt out of the body into scattered drops. These differences in the effects of action to blood can help tell the forensic experts of what truly happened in the crime and to the victim (Castillo, 2009). Blood Spatters and the Crime Scene The positions of the blood stains or the patterns of the blood can greatly help in the solving of crimes. As was mentioned, there are numerous ways in which blood may come out from the body once a violent act is done to disturb the circulation. Through these various effects on the blood spatters, forensic scientist are able to conclude what really took place in the scene. Blood spatter normally tell the experts five important and oftentimes incriminating pieces of information about the crime. The positions of the blood spatters tell first, the activity at the scene. Second is the number of blows the victim received from the suspect or suspects. Third is the position of the victim and the assailant within the crime scene. Fourth is whether the death of victim was immediate or delayed. The fifth and last things that blood spatters tell are the characteristics of the weapon utilized by the assailant in attacking the victim (Waldrip, 2008). There a number of ways to analyze a blood spatter pattern. Given a room where blood is all over the wall, a person may conclude that the traumatic attack have been done all over the room. However, carefully following the rules on blood spatter analysis, forensics will definitely disagree. One way of knowing this fact is through the string convergence analysis. The string analysis is a common means of analyzing blood spatters. It utilizes strings that are attached to the points where blood has dropped. For instance, on a wall filled with blood droplets, an end of a string is pasted while the other end is pasted on another wall with a droplet. This is done with each remaining blood droplet all over the crime scene. If looked at by ordinary people, the pattern that will be formed by this activity may mean nothing. It will only look like a web created from a ball of yarn of string. However, for forensic experts, doing this will immediately tell them what they need to know (Carter, 2009). The pattern that was formed from the strings may look like a cobweb in the eyes of ordinary people, but to forensic experts, it already told the position where the victim was attacked. If observed carefully, the strings which were connected always meet in one area. The intersection or convergence point of all strings is the exact position of the victim when the attack occurred. From this, any lie or alibi given in relation to the position of the body will immediately be dismissed. The blood spatters unlike men, can not lie. As such, it is commonly believed more by judges and jurors (Carter, 2009). After the position of the victim is found, another form of blood analysis is done. The distance of the blood from victim is then measured. The measurement that is acquired from the distance always corresponds to a certain spatter velocity. This velocity also corresponds to a certain type of attack done to the victim (Waldrip, 2008). Low velocity blood spatter is typically indicated by five feet per second and three millimeter diameter and is usually dripping. Medium velocity blood spatter is on the other hand, indicated by five to twenty-five feet per second with less than three millimeter diameter. This type of velocity is commonly caused by blunt force trauma or sharp pr knife trauma. The third type of velocity is the high velocity spatter, which is more than one hundred feet per second with a spatter of less than one millimeter. This is indicative of gunshot trauma, power tools, and objects striking with extreme velocity or an explosion (Waldrip, 2008). Through the analysis of these different velocities of blood spatter, forensic investigators easily learn what the weapon of attack was used (Waldrip, 2008). This helps in identifying the weapon even if the suspect has disguised it, hid it, or completely eliminated it. This may incriminate the suspect or point the true criminal during litigation. Another use of blood spatter is in telling the angle of the impact of attack. This will point the position of the attacker from the victim and from where his arms began the movement for the attack. The tail of blood spatter is the most important aspect in this analytic strategy (Waldrip, 2008). In this analysis the most important things to look at are the positions of the drops. Drops that are circular are always from vertical positions. This means that the attack and position of the victim is above. This drop is commonly on the floor. If the blood droplets are on the wall, its elongation should be checked. As the angle increases, the drops usually elongate. This points that there is an existing distance between the attacker and the victim. If the angle is decreased, this may point that the attack was done point blank or in shorter distance from the victim (Waldrip, 2008). Other than these strategies, there still remaining other ways in blood analysis. Sometimes, when the blood flowed freely on the floor of the crime scene, forensics can easily tell that there are objects removed from the crime scene, perhaps by the criminal or accomplices. When the blood flowed freely on the floor of the scene, the area where there is no blood indicates that there had been an object in that place during the time of attack. The shape that was left by the object may help in locating this object which may be used as evidence against the criminal (Waldrip, 2008). Given these strategies or ways in analyzing blood spatters, it may be said that blood spatters or patterns of blood spills is a crucial part of a crime scene investigation. The many ways in which the blood patterns in a crime scene may be analyzed helps in deciphering certain information that other pieces of evidence may not be able to tell. Even though blood spatters are hard to look at, looking closely at it may actually help in incriminating the suspect of a crime. Criminals should keep in mind that even though the victims died the blood they leave behind will point out what really took place, where it was done, how exactly it was done and more importantly, who had done it.

There are ways to analyze the blood spatters in a scene. The spatters can tell the acts that were done in the scene. It can also tell the area in the scene where the act was done. It can also tell the weapon that was used. Through this, the criminal who did the act may easily be incriminated and the judge and juror may easily give a decision.

The Hitchhiker’s Guide to the Galaxy Essays -- Literature, Douglas Ada

The Hitchhiker’s Guide to the Galaxy As the human race makes life-changing discoveries, it is made apparent that there is always more to learn as the universe, instead of becoming familiar, is becoming absurd. The Hitchhiker’s Guide to the Galaxy, written by Douglas Adams, as well as the 2005 film adaption, portrays absurdity to be an all-encompassing system in the universe. Through the introduction and attempt to understand lack of reason, the narration of important elements and the human perception of the universe, the novel is as a whole, more complete than the film. With these points it is irrefutable that The Hitchhiker’s Guide to the Galaxy develops the theme of absurdity with greater prowess than the film, resulting in a deeper understanding of absurdity, with an outlook the reader can connect to. The Hitchhiker’s Guide to the Galaxy introduces absurdity in a more compelling way than the film. The Infinite Improbability Drive "passes through every point in the Universe," (Adams 80). After being thrown out of an airlock, Arthur and Ford are rescued by the Drive with the â€Å"chance of rescue being 22079460347 to one against,† (Adams 67). Being rescued despite an astronomical improbability allows the novel to empower the theme of absurdity in a noteworthy way. The prominent focus the novel has on absurdity vastly differs from the minimal effort made in the film to evidently develop a source of absurdity in the universe, damaging The Hitchhiker’s Guide to the Galaxy. Furthermore, the novel’s depiction of the search for reason among the predominant lack of reason adds a very important human element to the understanding of absurdity. While undergoing the effects of the Drive â€Å"A million-gallon vat of custard upended itself over ... ... of this ideology in a way the reader can connect to. Through the foundation and attempt to understand the lack of reason, clear narration of important text and a human perception of absurdity, the novel prominently transcends the absurdity presented in the film. Absurdity is conveyed to be a school of thought, wherein humans attempt to answer and quantify the grandest questions of the universe, but ultimately come to a conclusion that the greatest answers are beyond us. As George Bernard Shaw said, â€Å"The more you learn, the more you know. The more you know, the more you forget. The more you forget, the less you know. So why bother to learn?† Works Cited Adams, Douglas. The Hitchhiker's Guide to the Galaxy. London: Pan Macmillan Adult, 2002. The Hitchhiker’s Guide to the Galaxy. Dir. Garth Jennings.

Mycenaean Civilization

The first great civilization on mainland Greece actually bloomed in the demise of the Minoan Civilisation. The Mycenaean Civilisation (1900 – 1100 BC) is also known as the Achaean Civilisation. This is due to the Indo-European migrants, who not only settled on mainland Greece but also adapted to the Minoan way of living. Independent city-states such as Pylos, Corinth and of course Mycenae which was the most powerful of them all, was a characteristic of the Mycenaean Civilisation. Mycenae was also the city of the legendary figure Agamemnon, who was one of the leaders who defeated Troy. These city-states were ruled by kings, whose palaces were on hilltops, enclosed within huge walls, which were very easy to defend. Mycenae with its impressive Gate of Lions became the dominating power in the Peloponese. These palaces soon appeared all over Greece, but unlike those on Crete, these were all huge fortifications and much more difficult to penetrate. As with the Cycladic Civilisation, an impressive legacy was also left by the Mycenaean Civilisation in the form of gold jewellery and ornaments. A collection of these treasures can be seen at the National Archaeological Musuem in Athens. The Mycenaean were also literate and wrote in a script known as Linear B. This script is an early form of Greek which is unrelated from Linear A from the Minoan Civilisation of Crete. It has however been deciphered. Other examples of the script Linear B have also been found on Crete, which has led to the possibility that the island may have been invaded by the Mycenaean people at around 1500 BC. At around 1400 BC the palace of Knossos was destroyed on Crete, as well as destruction all over the island. This wide spread destruction has led many to believe that Crete was not attacked by a foreign force, but that a revolt against the Mycanaean rulers had probably taken place. Mycenaean artifacts have also been discovered in Italy, Eygpt, Asia Minor and North Syria. It is likely that they had permanent strongholds in some of these places as their influence seems so strong. The defeat of Troy was accomplished with the Mycenaean city-states joining together to protect their Black Sea trade routes. During 1200 BC the decline of the civilization had began, with many Mycenaean structures being destroyed. The situation now in Greece was very similar to the one that had happened on Crete following the destruction of Knossos. It is difficult to grasp at how all of the city-states actually declined. Some have put forward that due to trade with the east stopping, many overseas settlements were lost. Others believe that along with factors such as famine and epidemics, internal battles and overpopulation, the reason was when the civilization was overtaken by the Dorians.
