For those of you who believe BR used the garrotte.
Would you agree that pretty much excludes that BR 'only' had an agressive personality, but rather a sadistic personality. He didn't only want to kill her, he wanted to hurt, degrade, and inflict agony upon her.
And if so, which of the 4 subtypes would fit BR?
I don't know enough to suggest a subtype, but one thing I haven't seen anyone say recently is that the ligature could have been some kind of "
control device" (i know this was suggested by some investigator, but I can't remember who, sorry!). Essentially a leash for her. It could have been presented to JBR as a game (one of her pageant applications noted she liked to "play kitty", as did I at her age).
I suspect there were many triggers for BR throughout the day, not just pineapple or presents. Jealousy (BR did NOT receive a new bike for Christmas as some have reported, he got one the year before. JBR & PR did get new bikes, hence the 2 in the photo.), annoyance (she was reportedly playing in his room that day with her friends, right in the doorway. maybe he did not like that or told her not to play in his room and she was like I'm not all the way in) tiredness (he was up around 5am) hunger (hence the snack) etc are all things that could have contributed to him being irritable. I can say from experience (oldest child) that it is a short step from irritation to all out violent anger in some children.
If he was less explosive in his anger, and more scheming, revengeful (the feces smeared chocolates suggest this) then perhaps all of his anger and irritation boiled over. He controlled her with the "leash", maybe intending to tie her to something so she would leave him alone or to get her to comply with sexual exploration. She, being tired and hungry herself may have begun to resist, leading to the blow to the head. She would have fallen when hit. If the "leash" was tied to something or was in burke's hand, it may have tightened just enough to keep her alive until the swelling of the area completed the asphyxiation.
Just spit-balling here, not really meant to be a fully fleshed out theory. As always, this is my opinion.
