I agree.  If  LV wanted Harry for himself, why wouldn't have Snape 
just stunned him, captured him, and brought him back to LV.  It 
seems he had ample opportunity to do either this, or AK him (up 
until the time that Buckbeak came), but actually stopped the other 
DE from using crucio on him.

Also, do the effects of a spell really stop when the wizard casting 
them dies in the HP books? Have we seen other instances of this ? If 
so, it would suggest the fidelus charm is no longer on 12 Grimmauld 
Place, as the secret keeper is dead.  If not, it would mean Snape 
somehow undid the full body bind on Harry so he was not left stuck 
in the tower. I would not have been too hard for Snape to put two 
and two together and figure out Harry was there -- two brooms, he 
knows about the invisibility cloak (though how would he know where 
he was, exactly?)
