Reportedly, Carl Sagan, once an ally of Randi's distanced himself after hearing these tapes. Benneth has posted challenges on the Internet to Randi and his supporters to provide a public confession before Benneth releases transcripts of the suffocation testimony. This may reveal something we all don't want to hear about, erotic asphyxiation, also known as asphyxophilia or hypoxyphilia, it is a paraphilia of the sacrificial type in which sexuoerotic arousal and attainment of orgasm depend on strangulation and asphyxiation. But there is an even lesser known and darker side of sexual hanging. In the gay community it's called scarfing.
Participants strangle one another for sexual arousal.
Sometimes it goes too far. In one Midwest case the owner of a thrift store strangled to death a huge number of gay men before he was suspected. Without sufficient evidence, after a year of fighting to get a search warrant, investigators seemed to have gone into shock when they discovered a wood lot in back of the suspect's home littered with human remains. As police reeled from their discovery, the suspect simply got in his car and disappeared. According to the survivor who turned him in, he did it simply for the thrill of watching humans die, to see their lips turn blue and crack, and their eyes bulge out.
