Zorro’s journey began with Puppies Behind Bars, a program that trains service and detection dogs through partnerships with incarcerated individuals. Following his initial training, Zorro was acquired by the Federal Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), where he was trained specifically in accelerant detection. In December 2016, Zorro and Nelson graduated from ATF Accelerant Detection Canine Class #117, marking the start of their impactful partnership. Known for his exceptional olfactory skills, Zorro has been instrumental in identifying accelerants such as gasoline and other solvents used in arson cases, contributing to the resolution of numerous investigations.
As an accelerant detection canine, Zorro followed a food-reward system employed by the ATF, completing over 130,000 training repetitions during his career. This specialized training method, requiring dedication and daily practice, underscores the precision and reliability that Zorro brought to his role. Now, at nearly 10 years old, Zorro will transition to a well-earned retirement, enjoying a more relaxed life and regular meals served in a bowl rather than from his handler’s hand.

Zorro’s retirement marks the conclusion of Nelson’s second partnership with an ATF-trained accelerant detection dog. His first canine partner, K-9 Charlie, served from 2008 to 2016. Together, Nelson and his canine partners have not only solved complex arson cases but also educated thousands of Maryland residents through demonstrations and public events. Currently, fewer than 70 ATF Accelerant Detection Canine teams operate across the United States and Canada, highlighting the specialized and essential nature of this program.
