I read somewhere that Patsy and John were no longer intimate after she initially became ill. Could be, that during that time, John entertained himself with porn, and soon found himself drawn into the world of child pornagraphy. I understand that he was very protective of his laptop computer and took it with him everywhere. I also read somewhere that John was taking Prozac for depression. A relative of mine was taking Prozac for depression and found himself walking across four lanes of expressway traffic one night because he believed he was invinceable. Needless to say, the doctor immediately changed his medication. I remember John saying that he took something to help him sleep Christmas night. The combination of drugs in his system could have had an adverse reaction, causing him to act out his sexual fantasies. John could have taken JonBenet to the basement, dressed her in erotic gear to take pictures, movies, whatever, when Patsy came downstairs to find out why he hadn't yet come to bed. He may have come up from the basement to answer Patsy, leaving his daughter unattended. JonBenet may have awoken from her "drugged pineapple nap", and struggled to free herself, not realizing that she was tightening the garrote around her neck with every move she made. When John returned to release his daughter, he would have found she had suffocated, and in a panic, staged the crime scene. John could have told Patsy that he suspected Burke accidentally killed JonBenet and the two of them contrived the kidnapper story to protect him. Who knows what really happened that night.
