District Attorney Investigators

The District Attorney’s Bureau of Investigations (DAI) is composed of sworn peace officers who work closely with our prosecutors to prepare and organize cases for court.

DAIs specialize by working in either the Trial Preparation Unit or the Special Prosecutions Unit within the SFDA’s Office. Investigators within the Trial Preparation Unit work closely with trial attorneys in the criminal division to supplement investigation in cases or, in some instances, build cases from the ground up. Their work ranges from serving subpoenas, reviewing and preparing criminal history reports, to conducting interviews of key witnesses and identifying and tracking down key pieces of evidence. Investigators assigned to the Special Prosecutions Unit provide similar types of support for cases involving: fraud, public integrity, justice integrity, elder abuse, environmental, and consumer fraud.

Investigators also perform a variety of other duties, including but not limited: witness protection and relocation in homicide and gang-related cases; respond to family child abductions; forensic analysis of computer and electronic evidence, and protection detail for the District Attorney. 

Given the diverse nature of our community, the ability to work with people of different backgrounds is critical.  The Office seeks to have a staff that reflects the diversity of the community that we serve. To that end, the Office is firmly committed to a policy against discrimination based on race, color, religion, gender, national or ethnic origin, age, disability, marital or veteran status, sexual orientation, gender identity, or gender expression
