If BM is included in the search, I'd want to accompany him and stay thisclose to him. If I wanted to go this direction and he wanted to go that direction then it's settled. I'd want to go anywhere he didn't want to go. And bring extra searchers.
On another note, way back when, I was intrigued by his day-before-the-TD-video sighting where he was seen sans shirt, red skinned and wet, gripping his steering wheel in an agitated state. I wondered whether SM was stashed somewhere in the water, maybe weighted down with large rocks and he was adding extra insurance to make sure she remained that way. Whatever caused SM's demise, if it happened in the home, I don't believe blood was shed, otherwise, BM would be resting comfortably in a jail somewhere.
If the gym he attends has another contest maybe they could bring in some rocks and see who can lift the heaviest ones and pile them in a cairn.
