Use of DNA Information as Evidence in Forensic
Forensic investigators rely to a larger extent on the DNA information collected from a crime scene to enhance their investigations or provide concrete evidence that will close their case, however, the use of DNA information as evidence is marred with series of issues that question the reliability of the process of collecting the highly susceptible DNA where a slight mistake can lead to a wrong prosecution, therefore, admissibility of DNA results as evidence of a crime in a court of law is seriously considered to ensure all procedures were followed correctly and DNA tests were conducted by a reliable DNA test lab. It is therefore important to find a criminal defense attorney to defend you in case you ever find yourself accused of a crime where DNA is among the evidence being used to pin you to the crime, the attorney you choose, however, need to be experienced defense attorney who is versed in DNA cases, DNA collection and testing procedure so that can question the reliability of the process to raise the reliability of the DNA evidence in the case. Although the use of DNA tests as evidence continues to become popular because of its matched ability to identify criminals, DNA cases are highly susceptible to errors, this article has outlined some common sources of these errors so keep reading this article.
The reliability of DNA results can be influenced by how the DNA was collected from the crime scene or the individual, the truth is even when a prosecutor is acting in good faith there are various points the highly susceptible DNA can get damaged, contaminated, compromised or even destroyed, this may happen during DNA collection, imagine all people who are involved at the crime scene police, witnesses, forensic detectives, and law enforcement support personnel, it can be difficult to tell how careful all these people were during DNA collection to avoid contamination or damage of the delicate DNA evidence.
DNA from a crime scene is mainly collected from bloodstains, dead skin, hair, etc but proofing that you collected enough to provide reliable DNA evidence in the courtroom is always a subject of discussion, furthermore, you need to proof and convince the jury and judge that the DNA was not comprised by exposure to cold or hot weather during collection and transportation to the lab for further analysis, police also need to assure the court that DNA collected came from a guilty person because an innocent bystander may be at the wrong place at the wrong time, all these possibilities make DNA cases complex as even when investigators are objective and thorough with their work such occurrences can exist which can send an innocent person to jail.
Human beings have over 99.9 percent DNA similarity with 0.1 percent being distinct to a specific individual, this makes it challenging for the forensic team to use DNA collected from a small sample in a crime scene which may be compromised or damaged as evidence, however, with modern technology reliability of finding the distinct 0.1 percent DNA from a small sample has seen DNA evidence becoming more and more admissible in courtroom. Those are some reasons why DNA cases are complex.
