A best friend of mine for many years now, Gabriel, was friends with Brian Bethel, who I had spoken to on a number of occasions. I remember him well as a stickler for facts and honesty, always using his words in a very deliberate manner. In result, this story of Brian's holds even more weight. His original telling was posted, by him, on an old newsgroup. It now, no longer exists. You can find retellings of it, but nothing compares to "hearing" it from Brian. Sure there could be plenty of explanations for it but...if I were you I'd watch out for the BEKs.
