The Forensic Science Division's (FSD) and the Technical Investigation Division's (TID) mission is to collect evidence at crime scenes and later process them at the Regional Crime Laboratory. Originally known as the Scientific Investigation Division (SID), it was renamed on September 6, 2015, following relocation to two sites. Founded in 1923 with a staff of two, SID was located in downtown LA until the FSD staff of over 300 moved to its present location in 2007. Following the renovation of the original site, SID was split into two units, with TID remaining in downtown Los Angeles, near the Police Administrative Building.

Forensic Science and Technical Division in the Major Crimes UniverseEdit

The job description for FSD and TID matches those of their real world counterparts.

The Scientific Investigation Division was renamed on September 6, 2015. This change has not happened in the Major Crimes Universe, therefore the Forensic Science Division and the Technical Investigation Division are still known as just the Scientific Investigation Division.
