John Kelly
John Kelly is one of today's preeminent serial killer profilers, aiding law enforcement in the pursuit of murderers through a comprehensive profiling process. He is a National Board Certified Addiction Specialist, Board Certified Social Worker, Certified Forensic Examiner and Fellow of the American Board of Forensic Examiners, as well as the founder and president of S.T.A.L.K. Inc. (System To Apprehend Lethal Killers). It was through S.T.A.L.K. that Kelly first enlisted the criminal-profiling help of DARK MINDS' anonymous source beyond bars, known only to audiences as "13."
