How Is DNA Evidence Used in a Criminal Trial?

Posted By David L. Carlson, Attorney At Law || 16-Nov-2015

Using DNA as evidence is commonplace in trials, as the technology improves, simplifying the investigative process. In fact, using DNA as evidence is a prime example of how cases are handled differently, even from a few years prior. It is the reason some cases can be resolved many dozens of years later on down the line. Either to convict a person or, in many cases, prove innocence and absolve someone of a criminal charge.

How Investigators Use DNA

DNA is collected from many sources. Forensic scientists and print specialists have primarily used fingerprints as a source of identifying suspects at a crime because fingerprints are unique to each person. This evidence can be used and stored in the database, ready for trial.

Here are some examples of DNA uncovered during investigation:

  • Hair strands
  • Blood
  • Saliva
  • Sweat
  • Fingernails
  • Teeth

DNA provides the same information. It is the individual’s genetic information, which is specific to that person. It can supplement the evidence in an investigation if fingerprints and other forms of DNA are uncovered. Or, it may be a reliable source of DNA when no viable fingerprints could be recovered. DNA evidence has elevated the precision and accuracy with which criminal cases are investigated. This gives those accused a fighting chance of proving their innocence.
