As the series progressed, additional supporting characters were added as allies of the detectives in the New York County Manhattan District Attorney's office (known as advisers from the Sex Crimes Bureau) and the Medical Examiner's office .

As of October 25, 2017, Law & Order: Special Victims Unit has aired 415 original episodes . </P> <P> The idea for Law & Order: Special Victims Unit originated with the 1986 "preppie murder" case of Robert Chambers, who strangled Jennifer Levin, a woman he dated whom he later killed during what he claimed was consensual "rough sex" in Manhattan's Central Park . The crime inspired Dick Wolf to write the story for the season one episode of Law & Order titled "Kiss the Girls and Make Them Die". Even after writing the episode, however, the case continued to haunt Wolf, who wanted to go deeper into the psychology of crimes to examine the role of human sexuality . </P>
