Hello...like many people, I have been thinking a lot about Joanna and what happened to her and why.
I gained the impression that Joanna was in the flat and had been disturbed there. Not sure where that came from, though. Perhaps from something that the prosecutor conveyed. Also although she had only been home for a very short time, is there not a suggestion that she had had a drink of the cider she bought in the off licence? That wouldn't have happened had he already been in her flat and she surprised him there and an attack ensued in which he killed her.
It's been mentioned that Joanna and Greg had not lived there long and that Tabak had been away for much of even that short amount of time. Yet there is some evidence of mutual awareness of the respective flats' occupants: an occasion when the cat caused some contact between them. Also, in regard to awareness, I noticed in the Daily Mail photographs posted above, that the Mail caption describes the window next to Joanna's bedroom as being the window of Tabak's bedroom. If this is correct and not just a reporter being inaccurate, his bedroom wasn't the flat's master bedroom which was far away from Joanna's but was his flat's second bedroom which adjoined Joanna and Greg's bedroom. That would mean that there was more potential for awareness of the presence of neighbours, and possibly of noise or everyday comings and goings, on the other side of the wall. The photograph shows that the windows of those two bedrooms are very close together. I wonder also if anyone knows who had lived in the flat before Joanna and Greg and whether there had been any contact or even tension between those neighbours and Tabak.
I lay awake last night thinking about the horror and sadness of this killing in the midst of ordinary life, with a young woman going about her everyday life, meeting friends after work, doing a bit of shopping on the way home, arriving home to the familiar comfort and security of home, kicking off her shoes and enjoying a drink at the end of the working week, with no reason at all to expect anything bad to happen to her, let alone have her life taken from her.
We can only speculate on the senselessness of this until we hear more of the prosecution case but I would hazard a guess that Tabak had more awareness of Joanna and Greg than they had of him, being absorbed in their own life together and their full and busy working, social and family lives. If something was bugging him, is it possible that he was mooching around the building that night because some tension and resentment had been brewing, maybe about cat nuisance, which led to some kind of confrontation? Or was he mooching around because he was some sort of voyeuristic personality, the kind who is psychologically something of an outsider, an observer, nose pressed to windows, looking in on others' lives but who crossed beyond that barrier and actually stepped into someone's life, driven by some demons that we do not know? Whatever it was that led to this violent attack and brutal killing, he was definitely not a normal person going about a normal happy and fulfilling life, as Joanna and Greg were. Something dark was there, which for whatever reason, was unleashed in a bout of extreme rage, fury or cold determined ruthless purpose on that night. And it is a tragedy beyond words for Joanna, her fiance, her parents, brother, wider family and friends, whose nightmare we cannot even imagine. He has no doubt added to their suffering by his lies, covering of his tracks and whatever concoction he has put together for this trial.
