Memorandum of Understanding, Investigative Process

















Independent Investigations Bureau (IIB)

A strong relationship of mutual trust between law enforcement and the community is among the most important tools for ensuring public safety. Communities are safer when law enforcement’s relationship with community members is built on cooperation and respect for shared values and rights. As the District Attorney’s Office, our commitment to public safety ensures our commitment to building trust between our office and the community we represent. It is our responsibility to hold all people, including law enforcement personnel, accountable when deemed just under the law.




IIB’s 3 Main Responsibilities

1. Investigate and review all officer-involved shootings and in-custody deaths.

2. Investigate and review all other excessive use of force cases.

3. Conviction review: assess and remedy individual colorable claims of innocence and broadly examine cases of misconduct discovered through a proactive, internal lookback process. Click here for a Conviction Review Request Form.
