Let’s Make Your Match During the history of forensic science, experts have discovered that using DNA in a crime scene investigation is a more productive way to find suspects rather than blood types and fingerprints. In criminal cases, DNA identification generally involves obtaining samples from crime-scene evidence and suspect, extracting the DNA, and analyzing it for the presence of a set of specific DNA regions or sometimes called “markers.” With this new discovery, investigators can prove a persons’ innocence more specifically and accurately than identifying just the persons’ fingerprints and blood types at a crime scene. DNA entered the courtroom for the first time as evidence in 1985, but it wasn’t until 1988 that DNA evidence sent someone to jail.
