The crime lab that is now referred to as the FBI Scientific Crime Detection Laboratory officially opens in Washington, D.C., on November 24, 1932.

The lab was initially operated out of a single room and had only one full-time employee, Agent Charles Appel. Agent Appel began with a borrowed microscope and a pseudo-scientific device called a helixometer.

Over the years, the FBI Crime Lab has grown to become one of the most advanced forensic laboratories in the world. It now employs hundreds of scientists and specialists who use cutting-edge technology to analyze evidence from crime scenes.

The lab has been instrumental in solving countless high-profile cases, including the Lindbergh baby kidnapping, the assassination of President John F. Kennedy, and numerous serial killer investigations.
