Special Deputies Program

Authorized by statute, Special Deputies, sometimes referred to as Reserve Deputies, are unpaid volunteers from the community that are used in a law enforcement capacity at the discretion of the Sheriff. Traditionally, candidates are approved and trained in the basics of safe law enforcement practices. They are most often used by agencies to augment the law enforcement presence at large events. In such a capacity, they are paired with a full-time, well-trained officer.


The Daviess County Sheriff’s Office uses Special Deputies, but not in the traditional manner they are used by other agencies. Our goal is to identify an individual who possesses a specific skill-set that will enhance our ability to serve our community. Those selected will be well trained and well versed in their particular area of skill. Once sworn in, they are called up for service when the situation requires the implementation of their skills. Currently, our Office utilizes the expertise of two such Special Deputies.

Special Deputy D. Allen Youngman is a native of Owensboro and a graduate of the University of Kentucky and the UK College of Law.  He retired from the US Army in December 2003 after more than 34 years of service.  His final assignment was Adjutant General of Kentucky where he was responsible for the training and readiness of the Kentucky Army and Air National Guard as well as the Kentucky Division of Emergency Management. 


His law enforcement service began after returning from active duty with the US Army in Viet Nam when he entered law school and was appointed a full-time investigator with the Lexington-Fayette County Alcoholic Beverage Control Authority (1975—77).  After graduating from law school in 1978, he returned to Owensboro and was appointed as a Daviess County Special Deputy Sheriff, serving in that capacity until becoming an Assistant County Attorney in 1982. 


He returned to full-time military service in 1987 and, throughout much of his career, was involved in developing firearms training programs.  After the attacks of September 11, 2001, he oversaw the creation of a special firearms training program for National Guardsmen who were subsequently stationed in each of Kentucky's passenger-service airports.  During that time he also directed the development and implementation of a close-quarters firearms training program for National Guard soldiers deploying to Iraq and Afghanistan that became the national model for such training. He retired from military service in 2003.  His awards include the Distinguished Service Medal, Silver Star, Combat Infantry Badge, Master Parachutist Badge and Special Forces Tab.


In 2004, he was re-appointed as a Daviess County Special Deputy and currently serves as the Senior Firearms Instructor for the department.  His primary responsibility has been to develop and manage an enhanced firearms training program for the Daviess County Sheriff’s Office, a program that was recognized for its effectiveness in the September 2010 edition of the FBI Law Enforcement Bulletin. In 2014, Deputy Youngman volunteered to be a liason between our agency and the Daviess County Public School System. Working with school officials, he has developed and implemented a training regimen for teachers, administrators, and school employees regarding an active shooter situation. He is currently training them in a six-step plan to be enacted should the unthinkable occur.


In addition to being a qualified military and NRA Range Safety Officer, he is a certified Live-fire Shoothouse Instructor/Instructor-Trainer and is a graduate of the Kentucky Department of Criminal Justice Training (DOCJT) Law Enforcement Firearms Instructor Program.  He has also completed numerous firearms training courses at  institutions such as the Gunsite Academy in Paulden, AZ, Rangemaster in Memphis, TN, the Kentucky DOCJT Rapid Deployment (Active Shooter Response) course and the Glock law enforcement firearms instructor and armorer courses. He is also a DOCJT-certified Concealed Deadly Weapons Instructor, a certified TASER instructor, and an NRA-certified Handgun Instructor as well as a co-founder of the American Academy of Personal Defense Firearms Instructors. 


He also serves as the Executive Director of the Defense Small Arms Advisory Council (DSAAC), a 501(c)(6) trade association comprised of most of the US-based military firearms manufacturers and represents that organization in venues such as the US Department of Defense, the US State Department, and the United Nations.  In January 2013 he was invited to take part in White House discussions led by Vice President Biden on ways to prevent school shootings and reduce gun violence.

Special Deputy Cheryl Purdy has been with the Daviess County Sheriff’s Office since April of 2011.  In addition to being a Special Deputy, Cheryl is an Information Technology instructor at Owensboro Community and Technical College where she teaches networking and computer forensics courses.  She has worked with our department on several occasions in the area of digital forensics, primarily mobile phone forensics, and, collection of digital evidence.  Using AccessData MPE+ (Mobile Phone Examiner), Deputy Purdy has performed forensic examinations on several cell phones.  Additionally, she has used screen recording software to capture security camera video to be used in court.  


As a result of our three-way partnership – Owensboro Community and Technical College, Owensboro Police Department, and Daviess County Sheriff’s Office, Cheryl is on loan to local law enforcement one day a week for retrieval and examination of evidence in cyber-related crime.  The forensic computer and software (AccessData MPE+ and AccessData FTK) used are provided by the Regional Computer Forensics Lab (RCFL) in Louisville.


Cheryl holds a bachelor’s degree in Mathematics from Kentucky Wesleyan College, a Masters of Business Administration (area of concentration:  Computer Information Systems) from Morehead State University, and Rank I and II status in secondary education from Western Kentucky University.  Additionally, she holds the following industry certifications:  CompTIA A+ and CCNA (Cisco Certified Networking Associate).  She has completed digital forensics training through the National White Collar Crime Center in Secure Techniques for Onsite Preview hosted by the Kentucky Department of Criminal Justice Training and Intermediate Data Recovery and Analysis hosted by the Tennessee Department of Homeland Security.


Cheryl’s professional affiliations include IEEE Computing Society (Institute of Electrical & Electronics Engineers, Inc.), ACM (Association for Computing Machinery), HTCIA (High Technology Computer Investigative Association), and Beta Gamma Sigma (International Business Honor Society).

In early 2014, we swore in our third Special Deputy, Jerry D. Humble. Deputy Humble brings with him expertise in many areas including rapid response training and planning, counterterrorism, and operational leadership. He is also an instrument rated pilot who owns his own single engine aircraft that may be used for aerial surveillance.


Maj. Gen. Jerry D. Humble, a retired two-star general in the U.S. Marine Corps, concluded a successful military career in January 2003. But instead of easing into retirement in Russellville, he accepted a Cabinet-level appointment to become director of Tennessee’s Office of Homeland Security.

Humble was born Nov. 4, 1947, in Jamestown. The former football player at Russellville High School and Western, graduated in 1969 with a degree in Social Sciences. In 1996, he was recognized on Western’s campus by the National Sigma Chi fraternity headquarters as a significant Sigma Chi.


He was commissioned in the U.S. Marine Corps in 1969 and began a career that included service in Vietnam, Desert Storm and numerous other operations. He commanded at every rank, helped develop numerous training programs and was recognized for his leadership and innovation. Tennessee Gov. Phil Bredesen cited Humble’s background in security and counterterrorism in naming the retired general as that state’s Director of Homeland Security.

Humble’s distinguished career includes serving with the British Commandos, commanding a Special Operations Capable Unit, and serving as Security and Special Operations Advisor to the Department of State. From 1995 to 1997, Humble was commanding general of the Marine Corps Recruit Depot at Parris Island, S.C. From 1997 to 1999, he was commanding general 3rd Marine Division. From 1999 to 2001, he served as commander of Marine Forces in Korea and director of plans, policy and strategy for United Nations Command Korea.


Marine Corps initiatives he helped develop include the Arctic Warfare Training Program, Expeditionary Special Operations Capable Training Program, Rapid Response, Raid Planning Program, Maneuver Warfare Training Program, Recruit Training Program (“The Crucible”) and Jungle Warfare Training Center.


Along with numerous campaign, expeditionary and foreign medals, Humble has been decorated with the Defense Distinguished Service Medal, Navy Distinguished Service Medal, Legion of Merit with two Gold Stars and Combat V, Meritorious Service Medal with one Gold Star, Joint Service Commendation Medal with Oak Leaf Cluster, Navy and Marine Corps Commendation Medal with one Gold Star, Navy Achievement Medal and Combat Action Ribbon.




We, as well as the citizens of Daviess County, are very fortunate to have such knowledgeable and capable people like Special Deputies Youngman, Purdy, and Humble working towards making Daviess County a better place for all of us. We are sincerely grateful for their individual and combined efforts.
