The Major Crimes Division Wiki


NOTE: The Los Angeles Police Department (LAPD) featured in the Major Crimes Universe is fictional but it's loosely based on the organization of the real LAPD from 2005, the year The Closer premiered. As such, it's presumed that the organization of the Detective Support Division is also mostly from 2005.

The Detective Support Division (DSD) of the Los Angeles Police Department (LAPD) is responsible for investigating missing persons, hate crimes, threats made to public officials/prominent persons, and aggravated stalking. The division is also responsible for enforcing firearm laws and processing concealed firearm license applications.

In the Major Crimes Universe, the MPU is also responsible for investigating missing juveniles (in the real LAPD, these investigations are conducted by Geographical Area detectives).
