About the Author

Author Info

Jesus First.

I am a devoted husband and father from Northern California who retired from the California Department of Corrections and Rehabilitation (CDCR) in 2023 after 27 years of service as a Correctional Officer and Gang Investigator.

From 1996 to 2023, I worked at Salinas Valley State Prison, Corcoran State Prison, Deuel Vocational Institution, and California Health Care Facility. Throughout my career, I always strived to be the best I could be, remaining committed to my profession, my responsibilities, and the lessons learned through years of experience.

In September 2023, I authored YARD DOWN: From the Crime Scene to Testifying in Court, a training book designed to educate correctional and law enforcement officers on crime scene awareness, investigative procedures, evidence recognition, and courtroom testimony as a gang expert. The book also addresses the importance of interacting with gang members professionally and developing mutual respect while maintaining the integrity and responsibilities of the job.

In September 2026, I authored Investigating a Norteño Soldado, a book designed to educate law enforcement professionals on the operations, structure, and activities of Nuestra Familia and Norteño gang members within the prison system.

My mission is to share the knowledge, experience, and lessons gained throughout my career to help educate, prepare, and guide the next generation of law enforcement professionals. I believe that experience has value when it is passed on to others, and I remain committed to helping those who serve understand the realities they may face in the field.

Strive, Hermano. Strive.
