Bureau of Criminal Investigation
Established in 1935, the Bureau of Criminal Investigation, or BCI, is the plainclothes detective branch of the New York State Police, with over 1,000 investigative personnel in its ranks.
Although uniformed troopers may completely investigate misdemeanor cases such as assault, larceny and criminal mischief, cases requiring extensive investigation or involving felonies are referred to the BCI.
In addition to conducting investigations initiated by the NYSP, BCI investigators regularly assist local and county law enforcement agencies that lack the investigative resources needed for major crime investigations.
