As far as the mountain lion story, it seems impossible and bothers me that BM is using that as a viable possibility. What is the likelihood a mountain lion could attack a grown woman, knock her bike into a ravine and drag her up a mountainside with no trace? He says it rained, okay well rain doesn't disintegrate torn clothing, gear etc. It would be a mess. It is safe to assume she was wearing a bike helmet so her head would be protected and she would have fought. To incapacitate her enough to drag her off, I would think we would see plenty of evidence of such a gruesome attack.
