CSI: Cyber (Crime Scene Investigation: Cyber, also known as CSI: Washington, D.C.) is the most recent spin-off from CSI. It is the fourth, final, and shortest series of the franchise. CSI: Cyber stars Academy Award winner Patricia Arquette and Emmy winner Ted Danson in a drama inspired by the advanced technological work of real-life Cyber Psychologist Mary Aiken. D.B. Russell, the Director of Next Generation Cyber Forensics, comes to the FBI fresh from a stint as the Director of the Las Vegas Crime Lab. Looking for a fresh start following the death of his best friend, Russell is recruited by now-Deputy Director Avery Ryan. Ryan heads the Cyber Crime Division of the FBI, a unit at the forefront of solving illegal activities that start in the mind, live online, and play out in the real world. She also knows firsthand how today’s technology allows people to hide in the shadows of the Internet and commit serious crimes of global proportion. Together, Russell and Ryan head a team including FBI Agent Elijah Mundo, an action-junkie and expert in battlefield forensics; Brody Nelson, an expat hacker; Raven Ramirez, a former black hat and an expert in social media; and Daniel Krumitz, who Ryan describes as the best white hat hacker in the world. Ryan's supervisor was originally Simon Sifter, a shrewd career insider who departed Quantico following a promotion. While other agents search for criminals in dark homes and alleys, Avery and D.B. search the “dark net,” a place deep in the bowels of the Web where criminals are anonymous, money is untraceable and where everything is for sale with just a keystroke.

The series ended the final season on March 13, 2016, then on May 12, 2016 the final active franchise was cancelled after two seasons.[1]


The series follows an elite team of FBI Special Agents tasked with investigating cyber crimes in North America. Based out of Washington, the team is supervised by Deputy Director Avery Ryan, an esteemed Ph.D.. Ryan is a behavioral psychologist turned "cyber shrink" who established the FBI Cyber Crime division and heads a "hack-for-good" program, a scheme in which the criminals she catches can work for her in lieu of receiving a prison sentence. Ryan works with D.B. Russell, a left-coast Sherlock Holmes and career Crime Scene Investigator who joins the team after a stint as Director of the Las Vegas Crime Lab. Together, Russell and Ryan head a team including Elijah Mundo, Daniel Krumitz (aka Krummy), Raven Ramirez, and Brody Nelson, who work to solve Internet-related murders, cyber theft, hacking, sexual offenses, blackmail, and any other crime deemed to be cyber-related within the FBI's jurisdiction.
