The missing tracksuit is strange but I do wonder what the point would have been to remove it? Re the blank Blackberry I actually wondered if one of Jiah's family members cleared it because the contents didn't look good for Jiah. Or Jiah herself because she didn't want people to see her conversations?? It clearly was a very dysfunctional relationship between Jiah and her boyfriend and there may have been a lot of stuff on that phone between the two of them which made neither of them look good.
The thing is we only have a snapshot of the information. Yes there was a strange mark on her neck but we didn't see the actual scarf she hung herself with. I wondered if the scarf had some sort of beading or embroidery on it that caused that oval shape. You would need to see the ligature intact to be able to fully comment.
When the boyfriend described Jiah cutting her wrists in an apparent suicide attempt he got a doctor there (who was interviewed and confirmed his story and also later said she suffered from depression) and went to the mother to tell her of the suicide attempt and saying he didn't know what to to do. The mother in interview said that wasn't true whilst the stepfather said they hadn't asked her about it because they didn't want to 'embarrass' her. There was also the suicide attempt after the failed court case in London so she did have the propensity to self harm which can sometimes go a bit too far.
I firmly think it was suicide. Murder in the circumstances given makes no sense. I could have understood it if the boyfriend had gone to her flat to tell her to leave him alone, there's been an argument and he's strangled her in a fit of anger and then set it up to look like suicide (although difficult to manoevre a dead body and hang it from the fan on his own) plus he didn't know who was going to return to the flat and when. However as it's clear he never entered the flat through the front door the only other way would be that he climbed up in through her window which was on the 2nd/3rd floor (and left the same way)? The only reason he would do that was if he was planning to kill her in advance and he didn't really have any motive that I could see. Also she died in a half hour period between 11 and 11:30. That doesn't leave much time for all this to take place.
The oddest thing I thought was when the boyfriend's father went to tell his son Jiah was dead. He said the that the first thing he said to his son was ,'Did you do anything to her' (or words to that effect). Really odd. It's not the first thing I would think of saying to my child if I'd just found out their GF had apparently killed themselves. Although maybe the father judges himself by his own standards.
The tracksuit disappearance is odd but the scene was never preserved and we have no idea as to who was going in and out. Did the family have servants who could have cleared up and thrown stuff away?
All in all very sad.
