About The Author
I am a retired California Department of Corrections and Rehabilitation (CDCR) correctional officer with 27 years of service. Ten of those years were dedicated to investigating gang members inside one of the most active institutions in the state. I began my career in 1996 at Salinas Valley State Prison, transferred to Corcoran State Prison in 1999, and in 2003 moved to Deuel Vocational Institution. In 2007, I was assigned to the Investigative Services Unit, where I learned how to interview, debrief, validate, document, photograph, and testify against gang members.
In 2023, I authored YARD DOWN: From the Crime Scene to Testifying in Court. In 2026, I wrote Investigating a Norteño Soldado, a training manual designed to teach law enforcement how Norteños operate inside a correctional setting and how to identify their structure, rules, and communication methods.
My mission is simple: to teach law enforcement more effective tactics for dealing with gang members—how to identify, document, and investigate them with precision. I focus on giving officers the tools to recognize gang indicators, conduct credible interviews, and build solid gang cases that stand up in court.
