After all, the prosecution's case was based on DNA evidence; Knox's genetic fingerprints were found by Italian police on the handle of a kitchen knife, which also had the victim's DNA on the blade Coupled with confessions from the murderers and DNA evidence, Williams, Adams, Rainge, and Jimerson were finally exonerated after 17 years in prison. In 1999, the Ford Heights Four won a $36 million in damages from Cook County—the largest settlement for a civil rights case in U.S. history From 1978 to 1998, 61 of the cases involved microscopic hair examination. As with forensic serology methods, DNA analysis (both nuclear and mitochondrial) has become more commonplace when hair is submitted as evidence. In these cases, 33 (54 percent) of the exonerees were African American, 24 (39 percent) Caucasian, and 4 (4 percent) Latino The mistakes of a single unidentified lab technician forced the New York medical examiner's office to review 843 rape cases for DNA evidence which could have been improperly processed. Supervisors might never have caught the mistakes if not for the fact that the technician in question applied for a new training program Forensic DNA evidence has been a game-changer for law enforcement, but research shows it can contribute to miscarriages of justice.

Mary Jane Burton had, against laboratory protocol, saved samples from some of the cases she had worked on. In 2001, evidence located in a similar manner exonerated Marvin Anderson. In 2003, the evidence Burton saved in Julius Ruffin's case was tested and exonerated him. In 2004, the evidence in Whitfield's case was subjected to DNA testing Defendants in about one-fifth of exonerations by DNA evidence were convicted at least in part on hair analysis that turned out to be wrong, according to the NACDL The New York City Medical Examiner's office had to review more than 800 rape cases from a 10-year period during which DNA evidence was mishandled by a lab technician. A San Francisco police crime-lab technician and a supervisor were implicated in alleged misconduct after processing samples despite having failed proficiency exams causing a review of 1400 cases Throughout that time, DNA testing and DNA exonerations have increased. In nearly half of the cases pursued by the Innocence Project, DNA exonerates the convicted, and in over 40 percent of the cases in which a convicted person is exonerated by DNA evidence, that same DNA evidence is used to eventually identify the actual guilty person He said another 36 cases were affected but did not need a replacement statement as the new figures were not below the original value. The specific category of crime scene DNA profiles affected.

While the DNA profiles were being entered, Sotolusson's name and the cellmate's name were switched accidentally. The problem is someone typed in the wrong name, Assistant District Attorney J. Charles Thompson said The emergence of DNA testing and the ability to use the science of the body's cells to solve crimes has made significant changes in the criminal justice field. However, in the past decades, DNA evidence wasn't available. As a result, hundreds of people were convicted of crimes they didn't commit Forensic technologies detecting and analyzing DNA evidence have been Traces of his DNA were found law enforcement must reduce reliance on DNA evidence while investigating a criminal case
The multiple murder trials in Virginia of Timothy Wilson Spencer were the first cases in the United States where the admission of DNA evidence led to guilty verdicts resulting in a death penalty But unlike DNA evidence, fingerprinting was adopted before the Supreme Court decided that attorneys and expert witnesses have to prove that evidence is scientific and reliable. There has been a hundred years of precedence, not a hundred years of data, says Ralph Haber, a consultant who has studied the reliability of forensic evidence In cases where the original physical evidence still exists, that DNA testing may shed new light on the truth. Damning report Even trusted lines of evidence, such as fingerprint analysis, are not. Myth 2: DNA Can Reconstruct Facial Features. Another myth surrounding DNA evidence is that it can be used to faithfully reconstruct the facial characteristics of a suspect. Phillips explains that the technology — called DNA phenotyping — does exist, but it's limited to sex, skin color, hair color and just a probability of eye color Over twenty years later a new confession, backed by DNA evidence, would prove that all five boys were innocent.

High-profile cases such as that of Amanda Knox — acquitted by an Italian court of murdering her flatmate after a trial that hinged almost solely on DNA evidence — have fed the notion that such. There were dog hairs on Leanne Tiernan's body, and scientists in Texas produced a partial dog DNA profile - this was the first time a British murder investigation had used dog DNA profiling. However, John Taylor's dog had died, so this could not be used in evidence The DNA results prove that testimony about the hair sample on which this entire case rests was just wrong, said Barry Scheck, co-founder of the Innocence Project, in a statement
DNA match is an authentic test, why it is not considered an evidence is something beyond my understanding and if it's not part of evidence then why it was conducted in 1st place DNA technology is rapidly becoming the method of choice when it comes to linking individuals with crime scenes and criminal assaults.

Bennett Barbour was convicted in 1978 of a rape he didn't commit.At trial, he had an alibi supported by several witnesses. He didn't match the victim's description of her attacker 15 Cases Where The Wrong Person Was Convicted. The prosecutors who had previously tried the case neglected evidence to suggest Richardson was innocent, the innocence project would reexamine his case finding his DNA did not match the seminal fluid found on the body, he was later exonerated double jeopardy is a good thing. this case had to have very specific things go wrong to cause a problem (their original evidence wasn't very strong and the techniques needed to analyze the hard evidence hadn't been invented yet). you have to remember, most crimes aren't grisly murders- without double jeopardy, we'd have prosecutors trying someone over and over for the same drug crime. The Registry provides detailed information about every known exoneration in the United States since 1989—cases in which a person was wrongly convicted of a crime and later cleared of all the charges based on new evidence of innocence.

The list of cases of people being wrongfully convicted based on eyewitness testimony, only to be later exonerated, is far longer than it should be (in fact the Innocence Project states that eyewitness misidentification has played a role in over 70% of convictions which were later overturned by DNA evidence) Research has shown that race and gender play a significant role in wrongful convictions. The New York Innocence Project reports that 70% of those exonerated by DNA evidence were racialized persons. As a point of comparison, approximately 61% of the American population are of Caucasian descent
In other cases DNA samples were not collected at the crime scene and preserved in a state suitable for testing today, or DNA testing of sufficient sophistication either was not available or not performed.
