I think the BW theory is one that LE should have investigated, what RA is accused of doing is equally implausible and far more difficult than BW taking them on a road to his home
RA we are to believe took 2 girls down a steep embankment, they all 3 had to have been walking unhindered ie not tied up in any way as to get down the hill would be difficult, he had to get both girls to the same spot to cross the river, the stàtes theory is he has a gun, but in going down the hill it would have been difficult to have it pointed right at the girls at all times, once down the hill he had to get them to wade across the stream and up very muddy steep embankment the other side, all in broad daylight, out in the open, and with no idea how many people were out on the trails that afternoon, still in broad daylight (with the possibility anybody could have been hiking or walking in the area, or the landowner walking on his land) he had to get them both to take clothes off, AW testimony wasn't sure if she took off bras and vest but she took off everything below the waist, he then had to put gun in pocket or somewhere else, then get hold of one girl fatally wound her then do the same to the other in broad daylight, he then redressed one victim, and then in broad daylight left the scene on foot had to walk out onto a busy road to get to his car, he had to have been soaking wet from river and i expect he had blood on him, LG testimony revealed was able to assert herself and would stand up for herself, but nobody heard anything that day, RA testimony was he was a fragile egg, seems to be totally reliant on his wife, is small for a man, and his personality IMO doesn't feel as dominant where he could control two girls, even if at gunpoint, and then when he put gun away to get knife, he could have just shot them, two shots in quick succession may not have caused alarm especially with testimony that hunting happened at the crime scene, but they were not shot and he then proceeded to spend more time at scene where he could have been discovered
So all that versus someone taking them into his house (I'm not saying I think BW did it, I am just opining on the theories of what BW would have to have done versus the states theory of what RA has to do
