In the criminal justice system, the best chance of a fair trial and justice lies within cases that include physical evidence. Physical evidence, whether fibers, fingerprints, or DNA, can give a jury proof beyond a reasonable doubt. Physical evidence can convict a criminal, or it can free an innocent man. It can bring closure to families and to the law enforcement that work the cases. The following cases will show what physical evidence does in a criminal trial and the vast impact it can make. For each case I will examine how the physical evidence was important to the case and whether or not it could have made more of a difference if the presentation of the evidence were different. The five cases are: the Mosley case, the Warren case, the…show more content…

Not to mention the significance of closing a case that was over thirty years old. In the next case, Edward Warren murdered an eighty-year-old mother and grandmother in Oregon in 1976 after her grandson cancelled a visit (Harden, 2009). Warren had been paroled on the very morning of the murder, and may or may not have known that anyone was home at the beginning of the breaking and entering (Harden, 2009). The victim, despite her age, scratched her attacker, and nail scrapings were taken that matched Warren (Springer, 2009). The DNA match was only made after a new system was brought into place with further capabilities (Springer, 2009). Warren later died while incarcerated for two more murders that he admitted to (Harden, 2009). The physical evidence in this case never got to be presented because the DNA system in place at the time of Warren’s death wasn’t adequate. In addition, Warren murdered two
