Mathematics Of Deciphering A Crime Scene

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

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.

Since the time that the scientific science dramatization "CSI: Crime Scene Investigation" turned into a tremendous hit and generated its fans, reporters have been worried about what they instituted the "CSI Effect." The hypothesis behind the effect is that fans of the well-known show disguise misguided judgments about the law that they bring with them into the court as jurors. In this way, the trepidation is that the TV show is at last influencing the results of trials - and not in a great manner. Criminal justice researchers have started to study the inquiry of whether nationals who are called to serve on juries bring unreasonable desires and convictions to the court as a consequence of TV projects. The impact that these projects may have on the jurors, their desires, and their choices is known as the CSI effect.

All these elements are important in uncovering the truth behind a crime scene, and in a controlled environment seem simple. Implementing these techniques in an actual situation is more difficult as crime scenes are all unique. A multitude of elements need to be considered before forming an opinion from blood spatter. Spot size, quantity, shape, distribution, location, AOI, and target surface are only a few of these elements. As with other types of forensic science negative evidence can be used in BPI.

Like you see in the Crime scene investigation shows like CSI and Bones, there are many things that go into investigating shows a lot of those things happen but it takes much longer than forty or sixty minutes to solve the crime. While crime scene investigating is very serious job, collecting evidence at crime scenes requires education and knowing of what you're doing, requires hard work, and it can be difficult to perform this job.

Today morning the Tangent Police Department ruled Mr. Rodriguez’s death a homicide after they found a note in his pocket with the statement reading “HE DESERVED TO DIE LIKE ME.” As a result, The Tangent Police Department have given me the duty of determining the time of Mr. Rodriguez’s death. To properly determine the time of Mr. Rodriguez’s death I will create a function of the time since police arrived on the crime scene using the Newton’s Law of Cooling, determine the percentage rate of decay for the body temperature, graph the function, and lastly estimate the time of Mr. Rodriguez’s death.

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.

When arriving at a crime scene investigators must wear protective clothing, gloves and shoe covers they must use

A crime scene analyst (CSA)), also known as a crime scene investigator or forensic science technician, supports police detectives or other law enforcement investigative teams by locating, collecting, and possessing evidence.

Investigating a crime can be a hard process but with the knowledge of CSIs, it’s good to know that they can get the job done by solving a crime and getting justice. Sometimes certain things are not what it seems like on TV but at least we can get a idea of what CSIs do and what they deal with when solving a crime. Being that the CSI: Crime Scene Investigation show is popular , they do a good job with portraying what real CSIs do in reality while solving a crime.

The CSI Effect began to fully take effect as the popularity for crime scene investigation televisions series became popular. One of the more prominent television series that contributes to the CSI Effect is CSI however there are several more like Criminal Minds, Bones, or Castle. In 2006 the weekly ratings taken by Nielsan determined that “five of the top 10 television programs [during one week] were about scientific evidence in criminal cases. Together, they amassed more than 100 million viewers” (Shelton, 2008). This fact emphasizes just how popular crime television is but more important what this fact shows is that more than 100 million people can be affected by the CSI Effect.

The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human;

The following information is an overview of some of the essential elements in conducting a thorough death investigation, as outlined in the U.S Department of Justice, National Institute of Justice’s Research Report titled “Death Investigation: A Guide for the Scene Investigator”. These observations and any possible recommendations, are intended to provide as comprehensive an overview of the materials covered as possible, and any further helpful material deemed necessary to improve the knowledge and abilities of the Forensic Crime Scene Investigator. (National Institute of Justice, 2011).

The purpose of crime scene reconstruction is to help determine what actually occurred or eliminating actions, events, or suspects through a methodical analysis of identification and examination of physical evidence. By recognizing and identifying the location, impressions, patterns and positions of physical evidence, as well as the scene presentation, an examiner or investigator can apply scientific methods, logic and past experiences to develop a theory in conjunction with information collected from a victim and witnesses (University of Split, n.d.).

While there has been criticism of the Holmesian method of deduction, many people support the idea that the use of deducing people can help with capture of criminals. While Holmes refers to his findings as deduction himself many people say, “that the process that Sherlock Holmes engages in is usually not deduction” (Novella). Deduction is defined as using a logic method of assumptions based on general statements about the world (Novella). However, Holmes himself makes more of an educated inference on what he observes about the suspects and evidence in his surroundings. The term “Holmesian Deduction” has been used to distinguish the two different methods (Novella). Holmes most famous quote, “when you have eliminated the impossible, whatever remains, however improbable, must be the truth”, is often cited as the best definition to his method of deduction. While it is not a method commonly used now thanks to more advances in crime fighting methods and technology, Holmesian deduction has certainly influenced that way we look at a crime scene.
