All evidence recovered at the crime scene leads to one person: Mr. O.J. Simpson. To begin, O.J. Simpson was in a broken relationship with Nicole Brown Simpson. In O.J. Simpson's book, he wrote, “...but to shake her up so badly that she'd finally start trying to get her shit together. The girl was an accident waiting to happen” (Simpson 135). These are certainly not the words of someone who is engaged in a loving relationship. There was a history of violence between the couple. Brown Simpson made multiple 9-1-1 calls on countless occasions regarding O.J. Simpson (Linder) and they had violent altercations as well (Simpson 133). All of O.J Simpson’s past anger came to a head and culminated on June, 12 1994. On that night in Brentwood, the two murders were committed by a heartless individual who had no remorse for his victims. The scene outside Nicole's apartment was gruesome to say the least. Goldman and Brown Simpson’s blood covered the once cement-colored sidewalk. The investigators found multiple pieces of evidence at the crime scene. Most of the evidence leads directly to O.J. as the perpetrator of the two murders. Detectives collected and examined hair, blood, and small fibers (Linder). Other incriminating evidence at the site included a bloody glove and multiple shoe impressions that match the ones found in O.J. Simpson’s white Ford Bronco …show more content…
Simpson was found not guilty of the criminal charges of murder. The results were broadcasted live and transfixed the public. Simpson’s “Dream Team” of defense attorneys including Robert Kardashian and Johnnie Cochran helped O.J. Simpson defeat the powerful prosecutor Marcia Clark (ABC News). After her defeat, Clark released this statement: "I felt like I'd let everyone down. The Goldmans. The Browns. My team. The country" (ABC News). She and everybody knew that O.J. Simpson was the killer, but she was unable to prove it. The result came as a shock to the
found behind the guest house was proven by DNA testing to have O.J.'s blood and
Even though the prosecution presented evidence to the court, the only clear-cut hard fact the prosecution had against Anthony was that she failed to file a report for her missing daughter Caylee and that when she finally did a month after her daughter had gone missing, she proceeded to lie profusely to the authorities on the events that took place. The prosecution focused highly on the forensic evidence of decay located in the trunk of Casey Anthony’s car. The use of a cadaver dog to search the vehicle led investigators to be able to determine that a decomposing body had been stored in the trunk of the car. The forensics department used an air sampling procedure on the trunk of Casey Anthony’s car, also indicating that human decomposition and traces of chloroform were in-fact present. Multiple witnesses described what they considered to be an overwhelming odor that came from inside the trunk as it where the prosecution believes Caylee’s decomposing body was stowed. Several items of evidence were ruled out to be the source of the odor, as experts were able to rule out the garbage bag and two chlorine containers located in the trunk as the source. The prosecution alleged that Casey Anthony used chloroform to subdue her daughter and then used duct-tape to seal the nose and mouth of Caylee shut, inevitably causing her to suffocate. Based off the
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
In 1994, football pro and actor Orenthal James Simpson was tried for the murder of his wife and a waiter. O.J.’s wife and the waiter were found murdered outside of her condo. O.J. and his wife had divorced to years prior to the murder, so in retrospect, O.J. automatically looks guilty. O.J.’s wife was found stabbed multiple times in the head and neck. There were also wounds on her hands, showing that she tried to defend herself from the assailant. The wounds to her neck were so severe, her throat was gaping wide open and her spine had been pierced by the blade.
look even more suspicious Nicole Brown had reported O.J. Simpson several times for beating her or threatening her life. In 1982, O.J. throws Nicole against a wall: In 1987, he shoves her to the ground; and in 1989, he slaps her and pushes her from a moving car these were just a couple times O.J.’s temper towards Nicole got out of hand ("101 PIECES"). Then again in 1989 police respond to a 911 call on New Year's Day to find a bruised and bleeding Nicole Brown hiding in the bushes, wearing only a bra and sweatpants, crying: "He's going to kill me! He's going to kill me ("101 PIECES")!" O.J. put on a good show in public but at home he was the complete opposite he abused Nicole for a long time and was unfaithful to her. After years of abuse Nicole finally had enough and filed for a divorce ("Nicole Brown"). That could’ve been what sent him over the edge. Once they were divorced Nicole was living a completely normal life until she realized everywhere she went O.J. followed ("Nicole Brown"). She had told her family she was scared for her life, but then they started talking and had a “On again Off again” relationship ("Nicole Brown"). A little while into it though she had decided she was done for good and wanted to be rid of him. She had told her family she wanted out of it, but shortly after her and her friend were found brutally stabbed to death ("Nicole Brown"). Finally to top it off in 2007 O.J. wrote a book that explained how he got away with murder, And
During the time that O.J was on trial for the murders of Nicole and Ronald, everyone who was following the hearing had a deep sense of fear and pity. They were fearing that the man they once adored and aspired to be like was actually capable of committing such an inconspicuous crime. Also, due to the accusations of the murder, the viewers were also feeling in the sense of pity, in both sadness and disappointment. The acts that O.J Simpson was accused of caused the audience to feel disappointed in his actions, as well as sadness towards his family. The accusations developed about O.J left people who didn’t even personally know him in tears. People were so sad about his downfall. The accusation led to the fact that O.J left his family with no mother and technically no father, as he’d be spending time in prison. Furthermore, since he was found not guilty, there was a large part of the audience that felt a sense of release and emotion, and some felt bad that he was ever accused of this, but rather he just in the wrong place at the wrong time. Due to the fact that O.J and Nicole were separated for a couple years before she died, Nicole had made new friendships, and there was no proof that someone new that she met could have caused this crime and tried to frame Simpson, due to his past accused abuse
On June 12th, 1994, Nicole Simpson and Ronald Goldman’s bodies were found Nicole’s condominium; the victims had been stabbed to death. The identity of the murderer was unknown up until O.J was suspected to be a suspect. When accused, he was in another state, and was forced to fly back. (Aaseng 1996)
Two detectives were assigned to the case: Harry Hanson and Finis Brown. [2] When they and the police arrived at the crime scene, it was already swarming with people, gawkers and reporters. The entire situation was out of hand and crowded, everyone trampling all over any hopes for good evidence. [2] One thing they did report finding was a nearby cement block with watery blood on it, tire tracks and a heel print on the ground. There was dew under the body so they knew it had been set there just after 2 a.m. when temperatures dropped to 38 degrees.
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. Unfortunately, this all came to an end when two bodies came to be spotted deceased in Nicole Browns front yard and was a gruesome sight. O. 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,
When the trial was happening, I had no idea who he was until the trial started. I had my Dad tell me all the details of who he was, and everything else I learned was from watching television. I was young, but I still knew that racism was awful. I looked upon the television to Simpson sitting in the trial and just thought, "Oh, okay." I know it 's hard to believe, but I wasn 't brought up to believe race had anything to do with whether people judged based on race, but this case was a 101 course in proving I was oblivious to the real world. However, what I did hear based on pure evidence was that this guy totally did it. There was too much evidence that proved he was involved, and the only reasonable doubt that was brought into the case was purely based on race.
On June 13, 1994, Nicole Brown, ex-wife of O.J. Simpson, was found murdered alongside Ronald Goldman (Dershowitz 19). Chapter one of Reasonable Doubts describes how many people jumped to the conclusion that O.J. carried out the murders. Incriminating evidence emerged that more than pointed to Simpson’s guilt (Dershowitz 21). Soon enough, media reports claimed that Simpson would be charged with two counts of first-degree murder. Simpson’s reluctance to be peacefully taken into custody was illustrated by his famous Los Angeles free-way chase that ended in his eventual surrender (Dershowitz 23). Dershowitz chose to join the defense team when offered the opportunity, claiming that the case could greatly educate people, especially his Harvard law students, on...
The prosecution says DNA tests place Simpson's genetic markers on the drops of blood leading away from the bodies. There were also blood samples, similar to Simpson's and the victims, found on O.J.'s Bronco truck. Simpson's blood was also found on his driveway and his foyer. The prosecution says Simpson cut his hand during the murder. The defence says Simpson cut his hand when he reached for his phone in his Bronco and later cut his hand on a glass. The main focus of the defence is the contamination of physical evidence.
The evidence discovered during the investigation suggested to the police that OJ Simpson may have had something to do with this murder and they obtained an arrest warrant. The investigators believed that they “knew” OJ Simpson committed the murders. His lawyers and him were informed of the arrest warrant and agreed to a specified time when OJ would turn himself into authorities. Investigators are later admonished, by the defense, on how they handled the crime scene.

In regard to the O.J. Simpson trial, this would have been a task easily accomplished. As the victim’s ex-husband and someone who was knowledgeable of Nicole Brown Simpsons daily routine, it would have been extremely easy for Simpson to place her in a specific place at a specific time. Unfortunately for Ronald Goldman, he happened to be returning a pair of sunglasses at that time, and became a victim himself. Following the deaths of Nicole Brown Simpson and Ronald Goldman, on June 17th, 1994, O.J. Simpson was charged with two counts of first murder under special circumstances. Some aspects of the crime that occurred proving O.J. After an investigation, a suspect is arrested, which is again only possible if the police have probable cause to believe the individual committed the crime.
