SANTA ANA, Calif. – Orange County District Attorney Tony Rackauckas announced today the selection of Paul M. Walters as the Chief of the Bureau of Investigation (Bureau) and Ron Seman as Assistant Chief for the Orange County District Attorney’s Office (OCDA) following a competitive recruitment process. The Bureau is the 32-unit law enforcement division of the OCDA, operating as an investigative agency. The Bureau consists of 130 sworn law enforcement investigators and 90 investigative assistants and technical support members, who provide trial support and investigate original jurisdiction cases.

“The OCDA is excited for this new direction of leadership in the Bureau. Chief Walters brings a unique skillset of knowing how to run a large police department combined with the skills needed to work as an executive in the County,” stated District Attorney Tony Rackauckas. “Assistant Chief Ron Seman led the office during a difficult and transitional time and proved himself to be an effective leader. We are excited to continue our great work in fighting gang crimes, human exploitation and trafficking, DNA and much more. The ever changing landscape of technology and the growing role of the Bureau make these positions challenging, and I am confident in Chief Walters and Assistant Chief Seman.”

It is the oldest nationally-known, non-profit, non-partisan, and non-membership-driven organization dedicated to improving America’s most noble profession – policing.

Walters earned a Master of Public Administration degree from the University of Southern California, Sol Price School of Public Policy. He received Bachelor of Science and Juris Doctor degrees from American College of Law, as well as a Bachelor of Arts degree in criminal justice from California State University Fullerton.

“I am honored to have been selected as the Orange County District Attorney’s Chief of Bureau Investigation and I look forward to serving the people of Orange County in this new capacity,” stated Chief Walters. “This opportunity will allow me to use my law enforcement and executive experience and lead the premiere law enforcement team of the county comprised of both sworn and non-sworn seasoned law enforcement professionals, while serving the skilled and knowledgeable prosecutors of the office, all of whom are dedicated to keeping the residents of the county safe.”
