The LADA Bureau of Investigation (BOI) functions primarily to provide prosecution support to Deputy District Attorneys. For example, BOI Investigators locate and process witnesses and conduct supplemental pre-trial investigations to help strengthen the prosecution's case. The BOI also has substantially staffed units with original jurisdictional responsibilities such as investigating local government corruption, complex frauds, and organized crime syndicates. Its staff also assists other law enforcement agencies with vehicular and electronic surveillance, undercover operations, and photographic services.

BOI in the Major Crimes Universe[]

In the last episode of The Closer, "The Last Word", Brenda Leigh Johnson leaves the Los Angeles Police Department for a job as Chief of the Bureau of Investigation. She also took David Gabriel with her to act as a liaison officer to the LAPD.

In the "Hindsight" arc of Major Crimes, one of the murder victims in the "Reese Murders" is DA Investigator Eric Dunn who was acting as a bodyguard for DDA Rachel Gray during the murder trial of Daniel Price. Both were shot to death during the Price trial, ultimately determined to be killed by Eric's own wife Stephanie Dunn due to Eric and Rachel's affair.
