DNA typing, since it was introduced in the mid-1980s, has revolutionized forensic science and the ability of law enforcement to match perpetrators with crime scenes. Thousands of cases have been closed and innocent suspects freed with guilty ones punished because of the power of a silent biological witness at the crime scene. 'DNA fingerprinting' or DNA typing (profiling) as it is now known, was first described in 1985 by an English geneticist named Alec Jeffreys.

1953: On April 1, the Scientific Laboratory moved from Broadway to a new, purpose-built, 7,500-square-foot structure at 8 Nolan Road in Albany, left. The new building included many features designed to be conducive to scientific criminal investigations, such as special rooms for lie detector examinations, serological analyses, microscopic examinations and other specialized work, as well as a museum for criminal exhibits, a motion picture projection room, a photographic studio and physical laboratory. 1964: In May, the Division opened its new headquarters building, left, on the State Office Building Campus in Albany, consolidating its administrative offices, Pistol Permits Bureau and Crime Laboratory in a single, central location. The move was part of a sweeping program of building assessment, re-evaluation, consolidation, construction and modernization implemented by Superintendent Arthur Cornelius Jr.

This was discovered in 1982 by latent fingerprint examiners at the U.S. Army Criminal Investigation Laboratory in Japan. This method is particularly useful in developing latent prints on household items such as plastic bags, aluminum, and rubber bands. Cyanoacrylate is the chemical used in Superglue. In addition to black powder, a white powder is used to develop latent prints. This white powder is composed of the chemical ninhydrin. The traces of amino acids present in...
