Yes, definitely agree that appearances mean absolutely nothing. However, I am *personally* getting an image of him as being the perhaps introverted type, kind of shy, and likely head over heels.. falls for this very outgoing and vivacious young woman, exactly the opposite of him, and suddenly his perhaps rather mundane, government worker life, becomes exciting, busy, and involving living with a beautiful young woman. I could see him being so smitten with her, and perhaps her choosing him because he was in love with her and good to her.. but then perhaps becoming bored. Who knows what some quieter types might do when, after getting a taste of the 'high life', are faced with 'mundane' once again? OTOH, he could be completely out of her picture really, if what MSM reported about them being 'separated' is true, even though still living together, and going through a 'messy divorce'? I just don't get why if that were true however, the family wouldn't have mentioned it, or the police.
If they *were* in fact separated and yet still living in the same home, I would assume that each would be living their own life without including the other in the fine details of where they are going, with whom, and when they will be back, etc. So while JB may have been the last person known to have seen her at 12;30am on November 27th, he could have then retired for the night and not know anything further. If they are apart, they are likely habitating in separate rooms and perhaps he would have no knowledge of what was in there, including her phone. It could have been dead, and she decided to go out partying, and left it at home knowing it wasn't going to work anyway, so left it charging, expecting to return. Unfortunately we don't know those details.
Someone could have picked her up at the house..... and nobody would be any the wiser, if in fact they *were* apart. So say JB then went to work as usual on that Thursday.. didn't see her on the Thursday, which, if separated, perhaps was nothing strange for him. Then he goes to work as usual again on Friday, comes home to nothingness which is again, perhaps nothing strange for him if they were apart. Then.. the weekend, which again, she had plans apparently in Edmonton.. and he wouldnt' necessarily know whether she showed up or not, what she took, what she was wearing, or that she had left her phone. Then on the Monday, the sister calls his cellphone to enquire about SB's whereabouts, so he goes home to see if she is there yet, and she's not, so he returns the call saying so. It could be all very innocent on his end, and he also wouldn't know whether, from the Thursday at 12;30am, through to the Monday when he heard from the sister, SB had in fact been in contact with any of her family or friends during that period or not, and whether it was only perhaps him who was left out in the cold as far as what she was up to. That is one of the big problems with people who 'separate' and yet remain living together.. they live together and yet they are separate lives and neither one has to answer to the other about anything. Seems so unfair, I don't know why anyone would agree to such an arrangement. MOO of course! Perhaps this is how they lived even when they *were* still together as a couple.. she was sleepless and energetic and outgoing, and he needed regular sleep to attend his regular job. They could have lived very separate lives even then.
Personally I do not believe she is alive either, but there are too many details that we don't know, in my opinion, to base an opinion as to who could be responsible. The 'ex' seems to be left holding the bag though, and would, I think, be the most obvious for police to follow up with. I wonder if her dog is still at the matrimonial home. I also wonder about previous 'flames', as mentioned by another poster. Hopefully LE has her computer wherein much might be found in the way of communications and perhaps plans with others.
