Why is genetic helpful in solving crimes?

DNA can be used to identify criminals with incredible accuracy when biological evidence exists.

By the same token, DNA can be used to clear suspects and exonerate person mistakenly accused or convicted of crimes.

In all, DNA technology is increasingly vital to ensuring accuracy and fairness in the criminal justice system. DNA is generally used to solve crimes in one of two ways.

In cases where a suspect is identified, a sample of that person’s DNA can be compared to evidence from the crime scene. The result of this comparison may help establish whether the suspect committed the crime.

In cases where a suspect has not yet been identified, biological evidence from the crime scene can be analyzed and compared to offender profiles in DNA databases to help identify the person who committed the crime.
