The Major Crimes Division (MCD), or "Major Crimes" as it is generally called, is an elite investigative unit of the Los Angeles Police Department (LAPD) which investigates cases that are mostly high-profile in nature.

The Major Crimes Division investigates homicides that involve multiple or high-profile victims and/or high-profile suspects; all cases involving missing, kidnapped or murdered LAPD officers; select sexual assault investigations and kidnappings; and select missing person cases including "critical missing" cases, involving children who are under 14 years old and/or have mental illnesses or disabilities. The Chief of Police or the Director of Operations can also assign the Major Crimes Division any special investigation that they deem necessary.

History Edit

The Major Crimes Division started out as the Priority Murder Squad, answering directly to Captain Russell Taylor of the Robbery-Homicide Division. After Capt. Taylor was replaced by Deputy Chief Brenda Johnson, the squad was renamed the Priority Homicide Division and placed under the direct supervision of Director of Operations.

The division was renamed as the Major Crimes Division in “Tijuana Brass” of The Closer, Season 4, after the LAPD came under criticism that it was assigning Priority Homicide cases in anticipation of newsworthy crimes, which primarily had victims who were white and/or rich.

The Priority Homicide Division, and later Major Crimes Division, was headed by Deputy Chief Brenda Leigh Johnson for seven years and following her retirement from the LAPD, command of the division was assumed by Captain (later Commander) Sharon Raydor. Following Commander Raydor's death in “Conspiracy Theory, Part 4”​​​​​, Lieutenant Louie Provenza assumed command of the division.

During The Closer and most of Major Crimes, Lt. Provenza was the division's senior member and the second-in-command for Johnson and Raydor. As the second-in-command, Provenza was the division's immediate supervisor in standard day-to-day operations. After Provenza assumed command of the division, the role of second-in-command was assumed by Lt. Andy Flynn.

Squad Room Edit


The LAPD's current headquarters, the Police Administration Building.

The Major Crimes Division is currently located in the ninth floor of the LAPD's headquarters, the Police Administration Building (PAB), located in downtown Los Angeles, next to the Los Angeles City Hall. The Major Crimes Division moved to the PAB in “The Big Bang” of The Closer, Season 6.


The LAPD's old headquarters, Parker Center.

The Priority Homicide Division (and later Major Crimes Division) was originally located in Parker Center which was the LAPD's headquarters until October 2009.

For Major Crimes, Season 5, the MCD received a miniature version of the RACR system used by the LAPD to their office. MCD can be seen using this new room extensively when going through large quantities of video material or when they are watching live-feed from surveillance operations conducted by the division and/or by the Special Investigation Section.

In Major Crimes, Season 5 finale, “Shockwave, Part 2”​​​​​, the Major Crimes' squad room was the target of a bombing, severely damaging it. In “Sanctuary City, Part 1”​​​​​, it is shown that the squad room has been repaired since the explosion and upgraded. These upgrades include a sliding wall between the murder room and Electronics instead of a simple door, although it still remains, and a TV connected to Buzz's computer that's used in conjunction with the murder board. Provenza's printer appears to have survived or been replaced and he continues to use the money jar for it.

MCD Trivia Edit

Call signs Edit

Sometimes when MCD personnel use their police radios to call for back-up or other support, they can be heard using some of the following call signs:

In the Major Crimes Universe, the Major Crimes Division appears to have the call signs of the 4-K-6 -series.

In the real LAPD, the call sign 4-K, or King as it is known in the LAPD's phonetic alphabet, is assigned to the Robbery-Homicide Division. The numerical designation, in this case 60, 64, and 65, would be assigned by the RHD commanding officer to a member of his/her division. Call signs ending in the number 0 are used by supervisory officers, although that usually means sergeants or supervisory detectives, not divisional commanding officers.

In the real LAPD, the call sign for the Major Crimes Division is 6-K (King). Major Crimes Division commanding officer would be identified by the word Commander followed by 6-K. All other personnel would be identified by 6-K, followed by the numerical designation assigned by the commanding officer. Call signs ending in the number 0 would be used by supervisory officers.

It's possible that the reason why MCD has call signs from Robbery-Homicide is because MCD was originally a specialized squad of the Robbery-Homicide Division (Priority Murder Squad).
