Was BTK Possessed By 'Factor X' Or Was He Selling It?

from History's Hidden Killers · host Hidden Killers Podcast

Factor X was a phrase Dennis Rader typed in a letter to a Wichita television station in February of 1978. He used it to describe what he claimed was driving him to kill. He compared the feeling to a demon. He compared himself to Jack the Ripper. He compared himself to Son of Sam. He asked the press, in writing, to call him the BTK Strangler.The press said yes.For forty-seven years, every documentary, book, and podcast about Dennis Rader has repeated his own language back to him, as if it were a forensic finding rather than a typed press release. Factor X. The Minotaur. The BTK brand. The mythology of BTK is the mythology Dennis Rader composed about Dennis Rader.In this first chapter of a new five-part investigation built specifically for BTK case followers, host Tony Brueski takes apart the language of the 1978 letter line by line. What Rader was reading at the time he wrote it. What classes he was taking at Wichita State. What books on profiling were sitting on his shelf. What cultural figures he chose to compare himself to. And the inconsistencies inside the letter that read, in retrospect, as somebody trying very hard to sound like the killer he had read about in his college textbooks.The episode also walks through how the Wichita Police Department first responded to the letter, how Chief Richard LaMunyon coined the term BTK Strangler in public for the first time, and how that branding moment turned Dennis Rader's self-marketing plan into official law enforcement terminology that has stuck for nearly half a century.If you have been studying this case for years, this episode is the version of the story you have not heard. The next four chapters go deeper.END LINKSJoin Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/ Want to comment and watch this podcast as a video?
