Mary] Lacy say they do not support her conclusion. That the DNA was not of a single person but from multiple people removes the "best evidence" for the intruder theory. Yet in Lacy became the second Boulder D.
Forensic personnel must pay close attention to detail during the collection, preservation, and analysis of physical evidence. For that reason it is imperative that forensic personnel are not only properly trained and educated, but they must also be of good moral and ethical character.
Many cases have been tainted do to unethical behavior; more must be done in order to prevent unethical behavior from taking place in the field of forensic science.
The field of forensic science is heavily relied on by the criminal justice system Holmgren-Richards, Forensic personnel are responsible for the collection, preservation, analysis, and interpretation of physical evidence Saferstein, The evidence, which forensic personnel are responsible for have a lot of weight in a wide variety of cases, but have a special importance when the evidence is being used in criminal cases Saferstein, All forensic personnel must be knowledgeable and skilled in their chosen area of study in order to do their job to the best of their ability and provide adequate forensic service Barnett, Forensic personnel must also be of good ethical and moral character Barnett, However, even the best people encounter situations where their moral and ethical standards are tested Barnett, Forensic science is able to reveal information such as who committed a crime, whether or not a crime was actually committed, and what exactly took place during the crime Barnett, If one piece of evidence is mishandled, manipulated, or misinterpreted a person's life could be destroyed or justice can go unserved Ayres, It is important that forensic personnel allow the evidence to speck for its self without any manipulation or errors Ayres, Most people believe that scientific analysis provide trust worthy proof in regards to the interpretation of the evidence, but what they fail to take into account is that the evidence is being handled by humans, which are capable of interpreting the evidence to best suit them Barnett, From the crime scene to the lab and in the courtroom it is important that forensic personnel always display good moral and ethical character, while providing trust worthy, high class forensic service Saferstein, The first place forensic personnel come into contact with physical evidence is at the crime scene Holmgren-Richards, There are policies and procedures that must be abided by in order to properly document and collect evidence Holmgren-Richards, If a crime scene investigator fails to abide by the set policies and procedures they are not only acting unethically, but they are also putting the case at risk Holmgren-Richards, In order to lessen the chances of evidence being mishandled, there is a chain of custody that must be established from the beginning to the end of the investigation Barnett, The possibility of evidence manipulation begins at the crime scene; here evidence can be purposefully or accidentally overlooked, planted, or mishandled The Innocence Project, n.
One reason why ethics is so important in the field of forensic science is because the results yielded by physical evidence discovered at a crime scene have a great impact on the lives of others Barnett, When evidence is mishandled, manipulated, or misinterpreted the outcome of the case is altered Ayres, The Simpson murder investigation is an example of how mishandled evidence can destroy a case.
During the evidence collection process at the crime scene hairs and fibers were collected from different areas and packed in the same bag, which contaminated the hairs and fibers Jones, Blood samples were also collected from multiple areas and packaged together.
The blood samples were also packaged in plastic bags, and then placed in a hot truck for storage Thompson, As many crime scene investigators know, biological samples should never be stored in an air tight container nor should it be kept in warm environments Saferstein, If biological evidence is stored in these types of conditions the evidence will begin to deteriorate and grow bacteria Saferstein, The blood evidence was also collected using gloves that were previously contaminated with by another biological substance Wang, During the evidence collection process evidence that could have provided useful information was tainted due to the careless actions of forensic technicians Forensic Science Central, n.
Due to the various mistakes made during the investigation the evidence collected did not hold up in court, and O. Simpson was cleared of all charges Yun Xu, After collecting evidence from the crime scene, the evidence must be analyzed. The analysis of physical evidence is one of the most important steps in the investigation Hopwood, The proper analysis of physical evidence can change the outcome of an investigation Hopwood, This is one of the times where the work of forensic personnel is capable for misuse by those who either do not possess the proper knowledge and skills required to perform their duties or by someone who is willing to manipulate evidence for their own reasons Barnett, Evidence can be contaminated, poorly tested, carelessly discarded, mislabeled or the results can be misrepresented by the technician The Innocence Project, n.
In order to avoid the possibility of evidence becoming tainted due to one not possessing the proper knowledge and skills required, most laboratories and police department require forensic personnel to attend periodical training and maintain current certification Hart, Even though efforts are made to reduce the possibility of evidence becoming compromised, too often evidence is mishandled, manipulated, or misinterpreted Barnett, Sometimes the evidence is compromised accidentally, but other times, forensic analyst purposefully manipulate evidence for various reasons Barnett, Init was determined that Steven Stokes, who worked for the Tucson Police Department's crime lab as a latent print examiner for 20 years had mishandled evidence in six criminal cases between December and January Phoenix Breaking News, It has not been determined if he mishandled the evidence purposefully or not, but as a result of his actions Stevens decided to resign Phoenix Breaking News, Init was determined that eight crime lab analysts at the North Carolina State Bureau of Investigation manipulated blood evidence or withheld important information from defense attorneys in cases San Francisco Examiner, The analysts manipulated evidence in order to help the prosecution.
Of the cases, of the convictions were unjust. Because of the tainted evidence three possibly innocent people were executed, four are currently on death row and two others are serving life sentences San Francisco Examiner, Forensic tools that once seemed to belong in the realm of science-fiction are becoming more real every day.
Scientists can now study a person's hair to determine what they have eaten and where. Dr. rer. medic. Mark Benecke · Diplombiologe (verliehen in Deutschland) · Öffentlich bestellter und vereidigter Sachverständiger für .
