If you’ve ever watched a crime show, you know that one of the most common methods of catching criminals is through DNA evidence left at the scene of the crime. Whether it’s a hair or a drop of blood, investigators can take seemingly the smallest amount of biological material and find the perpetrator. While this is often exaggerated for television, it’s important to understand that in real life, investigators do use DNA evidence to solve crimes. This advanced technology has drastically changed the way in which crimes are solved, so it’s important to understand how this evidence is used in investigations and the potential for DNA to help your case. The following blog explores what you should know about these matters, including the importance of working with an Oklahoma City felony defense lawyer to explore your legal options.
How Is DNA Evidence Used in Criminal Investigations?
One of the most prevalent ways that law enforcement will solve crimes is through the use of DNA evidence. Because the DNA makeup of individuals is unique, any trace DNA evidence collected at the scene of a crime can be logged. As such, during a criminal investigation, those who are believed to be involved in the crime may need to provide a sample of their DNA, most often a saliva swab obtained by swabbing the inside of the cheek. It is imperative to note that unless the police have a warrant, you do not have to provide a DNA sample.
Once DNA is obtained, it is tested and compared to any biological evidence left at the scene of the crime. Depending on the circumstances of the case, this can be used to show that the suspect was the perpetrator, or at the very least, at the scene of the crime, since their biological evidence was present.
Can This Help My Case?
While DNA is most often associated with catching criminals, in some instances, it can actually help prove your innocence. If the DNA sample you’ve provided does not match what investigators collected at the scene, it can show that not only were you not present, thus creates a solid defense for your case.
In some instances, you can also challenge the validity of DNA evidence presented against you. For example, if the chain of custody, meaning the handling and subsequent documentation of transfer, is not properly preserved, tampered with, or otherwise contaminated, your attorney can argue against the admissibility of this evidence.
As you can see, being charged with a criminal offense in which DNA evidence is present can be an overwhelming and complicated matter.
