He is a retired FBI agent who pioneered the profiling of sexual predators and much of the investigative approaches used today are routed in his research involving sex crimes including pedophiles, sexual sadists, autoerotic asphyxiation and serial killers. He is credited with developing the distinction between "organized" and "disorganized" murders, which continues to e used by law enforcement in the apprehension of serial power assertive, anger retaliatory and anger excitation. He also theorizes that pedophiles and sexual sadists are not subject to change. Mr. Hazelwood has and continues to provide forensic consultation in these areas to law enforcement agencies internationally and expert testimony to the courts. He has testified to committees of the U.S. House and Senate and before a Presidential committee. Mr. Hazelwood is a member of the Academy Group, an organization of former FBI and law enforcement officers, and continues to assist the FBI and other law enforcement agencies in cases involving sexually oriented murders. His work has focused on the Dennis Rader, better known as the B.T.K. Killer. He has co-authored two books, "The Evil that Men Do and Dark Dreams". He is a walking, talking, history making, one of a kind in his field.
