This is very sad and I agree that it does not sound like LE followed it through.
How far did your aunt typically walk? I would imagine that it would be very cold in NS at that time of year and as you mentioned due to the deep snow off the road she couldn't have waded off too far. I am trying to judge how much area LE would have had to search.
When you said she was a "thorn in the side of her ex-husband and his family" what do you mean by this? And what was their reaction (if any or known) did they have in regards to her disappearance. Are any of them in LE??
It really is not that long ago - colder cases have been solved through perseverence by family members. I hope it is true in this case as well.
I am not sure how you came to join WS but maybe its fate!
My mum thinks that it might have been raining those days (according to her memory), so perhaps the snow was not deep around there, and it might have been warm. My aunt was a very big walker, so it is possible she went fairly far, we aren't sure. My dad has searched the area assuming she could have gone off the road anywhere and gone for hours.
Now, with Paintr's info, it looks like she might have taken a trail there.
As to her ex - she was likely doing the average bitter divorcee-type stuff - calling him and harassing his new girlfriend (who was pregnant at the time, I think, so I can see why he wouldn't want her upset), and talking badly about them. She also had recently won a large divorce settlement, gaining half the worth of the house they had shared. (I was unaware of this until talking with my mum tonight. Such things are generally handled fairly discretely by my family.) To my knowledge, none of his family is in LE, but he might have friends - not sure.
It seems the local RCMP handled this whole case, and there were only a handful of them - my mum thinks only one or two had any involvement in this case. It's a small place.
I came to the forum because I've always had an interest in missing persons, and became really wrapped up in the Tori Stafford case, amongst a few others, and every time I looked at a cold case file, Google eventually led me here. After a bit of lurking time, I decided to join up. Thankful I did, now.
