What is DNA?
Deoxyribonucleic acid (DNA) is the genetic material used in the development, functioning, growth, and reproduction of all known organisms. In humans, DNA is unique to every individual (except identical twins), making it a powerful tool for identification in the criminal justice system.
DNA evidence can be collected from various biological sources left at a crime scene. Common types of evidence include:
- Bodily fluids such as blood, semen, saliva, sweat, and urine
- Skin cells left behind on objects through simple contact, like door handles or clothing
- Hairs with roots or follicles
- Tissue samples, like bone, teeth, and other materials
pre - The use of this evidence is dependent on proper collection, preservation, and analysis to ensure its admissibility in court.
How Does DNA Evidence Impact a Criminal Case in NJ?
DNA evidence provides compelling scientific proof that can significantly influence the outcome of a criminal case. For the prosecution, a match between crime scene DNA and a suspect can serve as corroborating evidence, establishing a link between the accused individual and the crime. This evidence often satisfies the “beyond a reasonable doubt” standard, especially in cases lacking eyewitness testimony or other evidence. This can lead to an increased likelihood of conviction. DNA can also be used to link multiple crimes together, establishing patterns that strengthen the case against a defendant.
While it can benefit the prosecution, DNA evidence is equally important for the defense. If the defendant’s DNA is not identified from crime scene samples, or the DNA of an unidentified third party is present, it can create reasonable doubt about the defendant’s involvement. Defense attorneys may also challenge the integrity of the DNA evidence by questioning the chain of custody, the methods used for collection and preservation, or the reliability of the laboratory analysis, which can lead to the evidence being deemed inadmissible in court.
DNA evidence has fundamentally reshaped the criminal justice system around the world. Besides securing convictions and acquittals, its use has been beneficial in exonerating individuals wrongfully convicted years prior. Despite the fact that DNA-based conclusions are based on probability, not certainty, it is still one of the most persuasive forms of evidence presented to a jury, influencing plea negotiations, trial strategies, and the public’s perception of guilt or innocence.
