DNA and Forensics


During the last 20 years, DNA analysis has developed into one of law enforcement’s most effective crime fighting tools. DNA analysis allows laboratory personnel to match biological samples from suspects to crimes scenes, crime scenes to other crime scenes and even crime scenes to family members of the suspects. DNA analysis has gained the attention of legislators for its ability to aid law enforcement in reducing crime, catching repeat offenders and exonerating those wrongfully convicted of crimes.
