Report 6: OJ Simpson EDTA Janet Boateng Forensic 5400 Analytical Forensic sciences This paper is the original work of Janet Boateng Ethylenediamine¬tetra¬acetic acid is also known as EDTA, a French-Swiss chemist discovered it by the name Alfred Werner. In 1893, he developed the theory of coordination compounds, also known as chelates. The first application of his discovery started in the 1820’s in Germany and later in the USA. When it was first introduce, it was initially applied to industrial and then later introduced for medical uses. EDTA is widely used in the medical field in treating lead poisoning and brain damaged; it is used in treat digoxin toxicity and also has made apperances in criminal cases (WebMD). In 1994, a California murder case of …show more content…
The tampering blood found rear a gate and the socks were all tested and compared to the blood from the test tube containing EDTA. All three methods identified that the blood was not planted by police officer, and that the level of EDTA was not very high, therefore the police had completely nothing to do with the blood found. The method that was used to conclude the result was LC-MS/MS. References: 1) PROVING THE CASE: DNA EVIDENCE IN THE OJ SIMPSON CASE. (n.d.).

Since the airing of the CSI: Crime Scene Investigation and the other televised series that followed have led jurors to compare fiction with reality. The shows have changed the view on the real world of forensic science as the series have a world of forensic science of their own. For this paper the televised series titled Bones by forensic anthropologist Kathy Reichs will be used as an example for comparison. In the series Bones Dr. Temperance Brenan arrives at the scene of the crime to examine the skeletal remains found in the scene of the crime equipped with one or more forensic kits. Upon momentarily examining the skeletal remains Dr. Brenan is able to determine the gender, ethnicity, and age. When this type of scenario is compared to nonfictional
In this position paper I have chosen Bloodsworth v. State ~ 76 Md.App. 23, 543 A.2d 382 case to discuss on whether or not the forensic evidence that was submitted for this case should have been admissible or not. To understand whether or not the evidence should be admissible or not we first have to know what the case is about.
One of the most coveted trials in terms of popularity and media attention the O.J Simpson trial which took place between 1994 and concluded on October 2,1995 with O.J Simpson being acquitted of charges laid upon him during the Murder Trial Due to handling of physical evidence and questions over whether Mark Fuhrman planted the bloody glove at the scene to frame O.J. so in an attempt to understand how a deviation from standard operating procedures in the handling of physical evidence can affect the outcome of a criminal trial; One most first understand evidence and how to preserve it. When the crime scene technician took blood samples from Simpson’s Ford Bronco (1996) she used a cotton swab to take samples; but instead of using

Because Simpson was the prime suspect, the judge legally ordered searches on O.J’s house as well as the crime scene. The goal was to find proof that he did commit the crime, by finding DNA or items. Shortly after the searches and tests began, evidence was found. DNA from the crime scene matched the DNA of O.J. Although proof was found, Simpson continued to plead not guilty. Surprisingly enough, O.J st...
In the following literature review, scholarly and peer-reviewed journals, articles from popular news media, and surveys have been synthesized to contribute to the conversation pertaining to forensics in pop culture in the courtroom and the overall criminal justice system. This conversation has become a growing topic of interest over just the past few years since these crime shows started appearing on the air. The rising popularity of this genre makes this research even more relevant to study to try to bring back justice in the courtroom.
A great deal of people viewed Simpson as a role model and someone they desired to be. Not for one second did any of those people even think about the thought of a man that “has it all” being on trial for murder. When most people view celebrities like Simpson, they imagine them with no flaws, but they only observe a glimpse of the person’s life. Some would say a majority of Americans prefer watching someone else’s life than pursuing their own, some Americans would even say that they have an infatuation with celebrities.

The blood of the unknown person became apparent through comparing the blood type found at the crime scene with the contrasting blood types of the suspects. The blood identified at the crime scene could have possibly belonged to Anna Garcia or Erica Piedmont. This observation was based on the information that the blood type found at the crime scene was type A and these two individuals are the only ones that carry that specific type. In similarity, a microscopic photography was taken of the unknown hair follicle found at the crime scene. Then hair samples were taken from the potential suspects, and the victim. These findings were then compared. This was done by looking at each individuals hair follicles and comparing it with the unknown one. By looking at the similarities and differences in medulla diameter, the discovery of the unknown hair follicle became established that it belonged to Anna Garcia. Further examination resulted in the analyzation of a shoe print found at the crime scene. Shoe patterns and sizes were taken from each suspect, including the victims. They were then identified and compared to the one found at the crime scene. By looking at the distinct pattern, size, and the fact that both shoes were a Columbia brand sneaker it became obvious that the shoe print was extremely similar to Anna’s shoe design. Through this found evidence it became
In here I will clarify each potential evidences of the crime and explain of the application of the identified forensic procedure to the facts of the case. One of the perpetrators cuts his hand when trying to drag of the witness in the crime scene. Thus, in this case blood stains would be the one of the potential evidence. The precipitin test might be applied to bloodstains in a numerous ways. It conduct...

Forensic science has been in practice for centuries; the first textbook on forensic science was printed in China during the 1200's; in the early 1800's, a technique was developed the first test to identify arsenic in the blood stream; the early 1900's lead to the development of using fingerprinting to identify victims and suspects. While these discoveries where important in criminal investigation, they were only the beginning. Only recently has forensic science significantly refined its techniques and accuracy. Today scientists can locate, identify and trace the tiniest of particles, and identify victims and suspects, beyond a reasonable doubt through DNA analysis. This evolution in forensic science is a prosecutor's dream; while a defense attorney's nightmare. Forensic science has made great strides.
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...
