When was DNA first used in CSI?

Alec Jeffreys discovered the forensic applicability of DNA in 1984. That was followed in 1986 by applying DNA to a criminal case in England, which led to the arrest of Colin Pitchfork, which I believe is the first documented case that was solved through DNA analysis. DNA slowly took hold throughout the world's crime labs during the 1980s, but it wasn't until the mid 1990s that the vast majority of forensic laboratories in the world developed the capabilities for conducting DNA analysis. And that came about as the result of a technique known as polymerase chain reaction, or PCR. And the advent of PCR in the early 1990s, and then with the equipment that become available in the crime labs in the mid 1990s was the spurt that led to the implementation and utilization of DNA throughout the forensic science community.
