Ahabmyth, congratulations on making a brief summary of the 1079 theory. Every one of your numbered questions has been addresses in the forum at sometime or another. The important difference is that in Teddy's 1079 theory, the unknown compelling force is the treefall. Alternately, on the slope where the tent was discovered, the unknown compelling force is unidentified and an open question.
One would expect that a fallen tree would leave evidence upon the tent, and those injured inside would leave evidence upon the tent inside.There is nothing in the case files to suggest a tree fell on the tent, nor blood stains within the tent. The tent was kept for a long time before being discarded. In all that time, no one pursued that line of inquiry and looked form supporting evidence.
There is also a question about crushed material items not being found.
In either situation, slope or woods, there are actions you would expect reasonable people to do. In each case, there is nothing we can point to that says, " because of this one partical truth, be it a person, place or thing, the tragedy had to have happened this certain way". This is why sometimes we take the grand view and other times we pick nits. Do not dispair, the Jack the Ripper mystery is older.
