The firearm was discussed a long time ago. It may have been Missy's gun, which some figured must have been in hercar. We wanted release of the 911 calls and Cannonball requested them. Those were not released, either, and that's when we learned about the exceptions of evidence that would not be divulged. There were early reports that MB was shot, which quickly disappeared, and we thought that if we could hear the 911 calls, maybe someone reported hearing a gunshot, or smelling gunshot, or at first look at Missy, THINKING her wounds were from (or one) a gunshot. So, it's still a mystery. If she was shot, and it had been with her own gun, we would have heard that. So if she was shot, its likely that they don't have the serial number of the gun that shot her....just the number of HER gun. JMO
