NYSI

Special Investigations (SI) division of the NYC Police Department, which handles cases in which something unexplainable or supernatural is involved and covering them up. Traditionally SI has been a dumping ground for officers who have made mistakes, and frequently SI officers leave the force. The commander, in particular, usually only lasts a few months. Currently in the hands of Ray Kelly and being taken more seriously as the supernatural world has encroached further and further into mundane lives.
