Shawn Henderson

The Evidence Management Institute and Executive Director Shawn Henderson share the same simple mission: To elevate evidence management practices, training and consulting across the industry. Shawn brings a unique and diverse set of skills and experience to EMI in pursuit of that mission.

Shawn retired from the Carrollton Police Department in July of 2018 after serving 18 years as a police officer. For  11 of those years he served as a sergeant, and five of those years he spent as the supervisor over the department’s evidence management and crime scene investigation units.  As an officer and supervisor, he developed curriculum, policy and procedures and provided training across multiple disciplines throughout his career.

During his time in law enforcement, he also served as a police training officer, a team leader of the North Texas Metro SWAT Crisis Negotiation team, police instructor, arrest control tactics instructor, and as was certified as a Crime Prevention Officer and trained in CPTED (Crime Prevention Through Environmental Design) security evaluations.

Since 2011, when he was first assigned to the evidence management unit, Shawn has actively championed the cause of evidence management, developing curriculum and training and instructing evidence management classes with the Texas Association for Property and Evidence Inventory Technicians (TAPEIT) where he also served on the board of directors.  Shawn also served on the board of directors of the International Association for Property and Evidence (IAPE) where he taught classes, as well as assisting in developing new curriculum and standards for digital evidence management.

Prior to his law enforcement career, Shawn served as an educator with the Carrollton Farmers Branch Independent School District, working as a middle school teacher and assistant principal. Shawn’s experience as an educator and an officer were a perfect complement to his work as the Executive Director of the Evidence Management Institute, in partnership with Tracker Products.

Shawn currently resides in Texas with his wife Michelle and his daughters Abby and Avery. Outside of his passion for evidence management, Shawn loves finding new regional barbeque joints and enjoys freelance writing about Texas/ Red Dirt music.

James Nally

James Nally is a 28 year veteran with the Orange County Sheriff’s Department 25 years. (March 1993)

Before his employment with the Sheriff’s Department, James proudly served as a Law Enforcement Security Policeman in the United States Air Force.

After the military, James started his career with OC Sheriff’s and worked several assignments including Correctional Facilities, contracted field operations providing Law enforcement services to a variety of County Facilities, and for the past 20 years, James has been assigned to the Sheriff’s Property & Evidence Unit.

“Having an understanding of both sides of the lockers has given me an objective perspective,” James says. I realize cops’ duties in today’s world are complex and demanding, yet as a support function of our agency, the evidence unit is here to ensure that all of their hard work is not lost on a procedural error. We also understand our neutral role as evidence officers can be even more daunting when it comes to the disposition and or the release of evidence items to the people we deem “lawful owners”.

James has been instrumental in a multitude of projects that have helped his unit lead the way in California. Some of the advancements include:

He has also been a leader throughout the state:

James is also married to his wife Stephanie of 17 years and a father. He enjoys spending time with his family, camping in the desert riding off road vehicles, bike riding, and watching his son swim competitively.
