Re the bolded.
I doubt we'll ever hear what really happened, we rarely do...unless he tells the story to someone else & they pass it on but who would know what to believe of that after the mega loads of lies he's told.
Re the suicide/depression. In the very first interview he gave along with OW, when Allison was missing, the vid in which she points to a spot on her head indicating where GBC supposedly fell over & bumped it....she was the one, I think, who planted the seed of suicide, when she said "Allison has depression".
It's a very elusive video & I've not see it around for some time.
