Dean Corll was a serial killer who abused and murdered at least 27 boys in Houston. Corll told his assistant that he belonged to a Dallas trafficking organization, later linked to Odyssey Foundation, run by John D. Norman, who was arrested on suspicion of supplying boys to Corll.
John Wayne Gacy was linked, through associate Phillip Paske, to John David Norman, who ran Odyssey Foundation (Dallas sex abuse ring) & published a CP newsletter. Norman may have had a connection to Jack Ruby: a '62 Dallas Apt deposit Ruby made to an agent named "John D. Norman."
