William J. Warner, “Bill,” retired from the FBI in 2012 with over 22 years of service as a Special Agent. He spent 16 of those years conducting polygraph examinations, 10 of which were spent supervising the work of other field examiners. Prior to his service in the FBI’s polygraph program, he worked as a street agent doing primarily reactive work on a violent crimes squad.

Developing skills through interview and interrogation (I & I), became his passion early in his career. As a former internal investigator for MARTA Police in Atlanta, he watched as a colleague collected confession after confession while he collected none. “I knew then what my mission was.” Shortly into his polygraph career he began honing his skills. “You have to truly care in all sincerity and be able to convey that emotion to the subject you’re interrogating to get them to tell you everything. Tough to do when you’re talking to a killer, child molester, terrorist or thief. I call it the ‘polygrapher’s paradox.’”

Bill has had a lifelong interest in writing. He owes his writing skill to a female graduate assistant from India at the University of Cincinnati who spent extra time out of class teaching him composition and creative writing. ‘If I could only remember her name I would acknowledge her in every book I intend to write.’ Bill’s second book, Holdup Number Six, An FBI Novel Based On Actual Events, was released early in 2015. Information concerning this roller-coaster cops-and-robbers epic can be found at williamjwarner.com.  Bill has also written for the FBI Law Enforcement Bulletin, April, 2005 issue, Polygraph Testing: A Utilitarian Tool. Bill is an active member of The Florida Writer’s Association as well as the Georgia Writer’s Association.

The author is a veteran having served three years with the 82nd Airborne Division with a son who spent seven years with the same division. His daughter is a registered nurse having once played volleyball for the West Point Military Academy. He resides in Canton, Georgia with his lovely wife of 36 years. He has additional passions for history, hiking, and baseball card collecting. When not writing, he can be found on a trail in the north Georgia mountains, the Smoky mountains, or somewhere along the Appalachian Trail.
