In the early 20th century. Dr. Edmond Locard, who is a forensic science. Formulate a theory based upon on “Every contact leaves a trace”. Locard method continuously known today society for all forensic science. Edmond not only paved the way to state his theory but successfully his results from an exchange of physical material .Showing his belief was no matter what criminals activity he or she may have committed by coming close to an object a criminal will always leave all sorts of evidence including DNA, fingerprint, foots prints fibers, hair, skin cells or even blood the list goes on and on. When approaching, at a crime scene there are often tiny collectable item of physical evidence such as hair, fibers and glass or even from clothing that can help reconstruct the crime scene into knowing what lies behind the true story on what in particular happen. These are referred to as trace evidence. Basically meaning “Trace Evidence …show more content…

From the beginning, of the O.J Simpson case there were issues involving evidence collection. The print was lost or destroyed without ever being collected. Other items of evidence were also never logged or entered into the chain of custody. Nicole Brown’s body was covered with a blanket which came from inside the house, this completely contaminated the body and anything the blanket touched around the body. Beyond poor evidence collection techniques. Throughout the investigation, there were issues with how evidence was secured. So many things in this case that shouldn’t have gone wrong but would have to save a lot of trouble on convicting the killer which was OJ Simpson. Eventually he did get away with murder due to evidence not properly handle and securing the scene. That should have been the first responder taking control. As for the lead Crime Scene Investigator of the case his actions speaking louder and clearly the day of trail day

    However, police should have acknowledged that individuals can make mistakenly identify the wrong person, especially an individual who had just tragically witnessed his wife’s death, and that the positive identification can not be the only evidence used to confirm the identity of a suspect. In addition, a search was never conducted on Butler’s home to see if any evidence was there. Unless my memory fails me, police officers also did not perform a gun residue test on Butler to see if he had recently fired a gun. Regardless, police did not find any physical evidence, such as blood, on Butler’s clothes or body. In fact, there was no forensic investigation of evidence conducted at all. Mary Ann Stephen’s purse was later discovered in a trash can, but it wasn’t until after the acquittal of Brenton Butler that a fingerprint belonging to the real killer was found on her purse. Overall, the ethical issues involved in the Brenton Butler case are astounding. The best solution to resolve those issues is to thoroughly perform job duties with integrity. Investigators had to know that more evidence than just a positive identification made by one, rightly upset individual was not substantial enough to confirm the identity of the

    ...on’s blood was found at the scene of the crime. There may be ways to plant such evidence, but it would be rather difficult to draw blood from a man without him realizing it and planting it at the scene of a crime. I also would have expressed that O.J. had a motive to kill his ex-wife, as well as a history of violent outbursts towards her. With all of the evidence that the prosecution had at their disposal, they should have been able to pin the murder on O.J. beyond a reasonable doubt. Everything pointed to O.J. and showed that he was the murderer. The only thing the prosecution was not able to do was fit the bloody glove on O.J’s hand. The only issue is, the glove was made of leather and had been soaking in blood prior to being found. When leather is soaking in a liquid, it tends to shrink. If only the prosecution had realized this, the case would have been theirs.

    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...

    After a lengthy two hundred and fifty-two-day trial “not guilty” were the words that left the world in shock. O.J Simpson was your typical golden boy. He had it all, the nice car, the football career, and his kids.

J’s ex-wife Nicole Brown and her friend Ronald Goldman both found with brutal stab marks. Unfortunately, all his glory days now brought to an end, he went from playing on the field to begging for his freedom when becoming the main suspect of their murders. Since this trial has not only altered the way Americans viewed celebrities, but it also racially divided society,

    The issue here I believe is with the justice system itself and not the direct actions of the prosecution or the police involved. The blame isn’t really so easy to point out honestly. If anyone is to blame at all it would be the people who tampered with the crime scene and the potential failure/inability of the police in preserving the scene if it was possible.

  • The O.J. Simpson Trial

    My opinion about this case is that O.J. Simpson is guilty. The defence tries to say there was all this conspiracy to frame O.J. but I don't think they proved any of this happened. The defence said Furhman was a racist but this does not prove that Simpson didn't commit the crime. They say the blood samples were contaminated but I don't think every single one was. The prosecution proved he was an abuser and I think something finally snapped inside him and he killed Nicole and Goldman. The gloves the killer wore were the same type O.J. wears. When they say O.J. tried on the gloves and they didn't fit I think he tightened his hand up so the gloves would be hard to put on. The shoeprints at the crime scene were the same style and size he wears. Bloody clothes or a murder weapon have never been found but neither has the missing laundry bags from O.J.'s hotel room. I have to wonder why O.J. lead the police on a big chase if he is so darn innocent. My opinion is that O.J. Simpson would have been found guilty a long time ago if it wasn't for all the publicity surrounding the case and the fact that he's famous.

    Things only got worse when it was alleged that he transported and planted one the gloves on the Simpson estate, and the defendants legal team stating the officer wanted to frame Simpson because he was black and he disliked blacks an considering the jury was made up of mostly minorities this helped O.JSimpson even more.(2015) The key to winning a case apart from collecting evidence there must be a clear way to paint a picture that the people of the jury can understand whether or not you done the crime one must be convincing. Even though Simpson’s blood was on majority of the evidence collected it was argued that he was framed along with the contamination of evidence even if he had done it his team used all the weaknesses exposed by police involved in the case to paint a picture of innocence to the jury which proves perception of wrongdoing as persuasive to a jury as actual wrongdoing. I am sure with O.J Simpson being acquitted of the charges left a bad taste in the mouth of both police and some people in the legal field. There were too many mistakes made by the people that were tasked with the duty of collecting evidence and also in the department of how the evidence was handled but there are many lessons to be learned in every mistake the obvious one would be to not make the same ones

    The relationship between law enforcement and prosecutors, which goes hand-in-hand, can’t be overlooked. Evidence of a crime that detectives and law enforcement discover is as equally important as a good trial on part of the prosecution. If detectives aren’t able to find good solid evidence – that case usually isn’t bothered in being pursued. Several years ago, in the late 80’s, there was a murder case in Southeastern Oklahoma which now serves as a tragic example to the need for honest, constitutional work in the criminal justice system. Disreputable investigative procedures, fraudulent sources, and bad evidence were the foundation of this case that shattered innocent lives.

    The Locard’s principle is important in any forensic science field, “the principle holds that the perpetrator will take away traces of the victim and the crime scene; the victim will retain traces of the perpetrator and may leave traces of himself or herself on the perpetrator; and the perpetrator will leave traces of himself or herself at the crime scene in many ways” (Geberth, 2007). The Locard’s principle in BPA is applied in the retrieval and evaluation of bloodstain pattern evidence.

    Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.

    As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the
