Technical Investigations Unit

The Sheriff Department’s Technical Investigations Unit conducts special investigations which often require the use of advanced surveillance equipment and tactics, resource networking, and undercover operations. They perform threat assessments and threat management regarding threats against Orange County employees.

The team performs dignitary protection, as needed, often in cooperation with the United States Secret Service, United States Capitol Police, California Highway Patrol and Department of State. These events include; conducting site assessments, planning personal protection of visiting dignitaries, and planning travel routes/motorcades.

The team also monitors subjects in the Armed Prohibited Persons System (APPS) and works in conjunction with the Courts, County Probation Department and the California Department of Justice/Bureau of Firearms to collect data on APPS subjects. Investigators regularly conduct site checks on these subjects to verify compliance with court orders.
