Billy/Matthew Johnson??
I've read alot about this McMartin case, and I did find it quite disturbing (2 year old boy is forced to have oral sex with Ray Buckey's mother, Baby's head's cut off etc.) I found a picture: http://www.law.umkc.edu/faculty/projects/ftrials/mcmartin/realtunnels.jpg on the net. Is that Billy Johnson the one Standing up and looking the other way? (The little boy on the far right hand corner, looking the other way.)
