The DNA profile was produced from a bloodstain found near the ankle of one of the socks. Shortly after the crime, police collected blood samples from a vehicle belonging to OJ Simpson.
When tested, samples collected from the console, the steering wheel and the carpet of the car produced probative results. The prosecution experts gave evidence that this sample taken from the console produced a mixed DNA profile consistent with OJ Simpson and Ronald Goldman.
However, a defence expert refuted this conclusion and testified that the tests were inconclusive due to a failing control during the assay. The sample collected from the steering wheel showed a DNA profile that was consistent with OJ Simpson and a second, unknown person.
The sample from the carpet contained a profile consistent with Nicole Brown Simpson. Police also collected blood samples from the vehicle over two months after the homicide. Police also found blood in the driveway and foyer of the property belonging to OJ Simpson. Tests showed that this blood belonged to OJ Simpson.
Many more pieces of evidence were adduced during this trial. It is likely that the other pieces of evidence, some of lacks forensic relevance, also played an critical role in the outcome of this trial. There were two pieces of physical evidence relied on by the prosecution:. The prosecution also argued that blood splatter transferred from the victims to OJ Simpson during the murders had been transferred to his car from his person and from the glove which was later found behind his house saturated blood.
Evidence had been mishandled during the investigation. Other evidence: 1 flight in Bronco, 2 strange reaction to phone call informing him of Nicole Brown's death, etc. Simpson did not testify at his criminal trial. Defense attorneys will almost always call as a witness an articulate client that they believe to be innocent.
Subsequent to the trial defense attorneys talking about the trial have been careful to say "the jury did the right thing," while not stating that Simpson was in fact innocent. Subsequent to the trial, Simpson has devoted no real effort to tracking down the "real killer," nor has any significant evidence surfaced suggesting that the killer was anyone other than Simpson. The jury was not allowed to hear testimony concerning Simpson's rumored jailhouse confession to Rosie Grier.
Subsequent to the criminal trial other evidence of Simpson's guilt surfaced. There was about 1. To add to the problem, the blood was not immediately turned over as evidence but was carried around for several hours before it was entered into the chain of custody, allowing for speculation of when and how the 1. The security of LAPD storage and labs was also brought under scrutiny when it was discovered that some pieces of evidence had been accessed and altered by unauthorized personnel. A Question of Planted Evidence Not only were there many claims that the evidence was mishandled in the police lab but there were also claims that evidence was planted at the crime scene.
The defense team stated that EDTA was found in the samples of blood that were collected at the crime scene. EDTA is a blood fixer anticoagulant used in labs and mixed with collected blood. However, EDTA is also a chemical found naturally in human blood and chemicals such as paint. Some believe that the positive EDTA results may have been due to contamination of the equipment used to run the tests.
A Question of Character Detective Fuhrman was discredited by the prosecution when he was alleged to be a racist and accused of planting evidence. When asked if he had falsified police reports or planted evidence in the Simpson case, he invoked his 5th Amendment rights against self-incrimination.
This put anything he touched in the investigation under scrutiny. Understanding Forensic Science A major hurdle that the prosecution team failed to overcome was the lack of knowledge and understanding regarding forensics, specifically the relatively new science of DNA. The jurors agreed that the DNA testimony was difficult to appreciate since expert witnesses were not able to put their evidence in terms that the jury could understand.
