Detective Bureau in the Major Crimes Universe Edit

Command Edit

The command of the Detective Bureau, including the Chief of Detectives and all divisional commanding officers, is currently unknown.

Robbery-Homicide Division Edit

In the Major Crimes Universe, the Robbery-Homicide Division's investigative responsibilities, especially those involving high-profile murder investigations, are severely reduced because of the existence of the Major Crimes Division.

Detective Support and Vice Division Edit

Forensic Science and Technical Investigation Division (Scientific Investigation Division) Edit

Forensic Science and Technical Investigation Division was originally know as the Scientific Investigation Division (SID), it was renamed on September 6, 2015, following relocation to two sites. This change has not happened in the Major Crimes Universe, therefore the divisions are still known as just the Scientific Investigation Division.

Gang and Narcotics Division Edit

The Gang and Narcotics Division was created in 2009 with the merger of the Narcotics Division and the Gang Operations Support Division to combat the gang and drug problem in LA.

The Gang Operations Support Division was a relatively short-lived division of the Detective Bureau which presumably was never even created in the Major Crimes Universe. The Gang Operations Support Division contained the Gang Support Section which was moved from the Special Operations Bureau's Special Operations Support Division when it was transformed into the Emergency Operations Division.

In the Major Crimes Universe, the Gang and Narcotics Division is still known just as the Narcotics Division, as the aforementioned merge(s) haven't happened.
