This is my first post, so if I sound dogmatic please just shake your heads sadly and mutter"newbie". I've felt very strongly about this ring business for a while now. Let's apply occam's razor to the possibilites:1) DF is in the process of offering the ring to BLJ when a maniac storms around the car firing into it and 'herding' them out in a panic and he doesn't DROP it???2) Robbery gone bad: instead of simply waving his gun in the open window (let's not even start on that one!) he 'herds' them out and then asks, not for cash, but a ring -and then shoots DF in the process of handing it over and then leaves w/o it?3) It simply falls off.4) Butterbach's assumption that DF prevented Z from taking a trophey by clutching the ring is impossible. I'm no 'brain surgeon' but I have consulted experts on this point: the bullit passed thru the portions of the brain that control consciousness and voluntary function -DF was tragically brain dead before he hit the ground. He was only still weakly breathing because the amygdala was still intact. If Z wanted to take a trophey he simply grabs the ring. DF wouldn't even know about it, much less be able to stop him by clutching it in that peculiar manner. sooo...5) After killing BLJ Z returns to DF and POSITIONS his fingers! Butterbach's immediate police report [which is far more reliable than an older man's 40 yr old recollections] seems to imply that he saw the ring at the scene and the ring was held between "the middle and ring finger" [and the thumb]. Try it and look at your hand. That symbol means either a) "hook 'em horns" b)'"rock on" [but not yet in 1969]or...(here's where you shake your heads and mutter) c) the GOAT OF MENDES -a very prominant satanic hand signal. Now add in the tips about an occult group in the Vallejo area that were ignored by police, the drug angle, and take it all in the context of the times [in the sixties no place was "the sixties" like SF -capital of LSD, hippies, satanism and the counter culture]. Remember your Sherlock Holmes: "Once you eliminate everthing else, whtever remains must be so. OK, you can shake & mutter now.
