2020 Annual Membership Meeting



DIA by-laws require an Annual Membership Meeting.  However, due to the pandemic caused by COVID-19,  DIA will not be having an in-person live event.   Instead, we invite all DIA members to join the Executive Board online for an update on the organization.  A link will be sent to all active and associate members to a GoToMeeting.  If you haven’t received a link CONTACT us or JOIN NOW!

The DIA is working to continue to support defense investigators.  We have regular webinar trainings, so check out the DIA Calendar for updates.  












Investigator of the Year


The DIA likes to recognize Defense Investigators who exemplify the work ethic and passion it takes to pursue justice for our clients. Our profession attracts the best and the brightest, not to mention those with big hearts. Please nominate someone who you feel meets these standards of excellence!

Police Misconduct Information

State Supreme Court rules that law enforcement agencies can share misconduct information about officers with prosecutors, making such info available to defense as Brady materials, supplementing SB 1421. Pitchess still applies.

DIA Single Day Seminars!

All DIA members can participate for FREE!

Social Media Seminars were a hit in 2019.  Keep an eye out for our 1-Day Seminars in 2020 with special speakers from the DMV.  You may have access, but there is a wealth of information and it's important to know how to decipher it.

Not a member? Well then, you're out of luck... that is unless you join as an active or associate member today!

Orange County Jail Snitch Scandal

In 2015, California State Attorney General’s office opened an investigation into both Orange County Sheriff's Department and the District Attorney's Office.  The U.S. Department of Justice followed suit the next year. Orange County prosecutors were kicked off Dekraai’s cases and the American Civil Liberties Union filed a lawsuit accusing authorities of having deployed “professional” informants for decades.
