I've rarely come across French, and I'm in Alberta. I did hear more of it when I was travelling closer to Quebec.
I also had the thoughts about dogs. Everyone has one it seems. I wonder if there was anytime the dogs went nuts. I can't see domesticated dogs going after them, but maybe strays?
There has to be a reason why the RCMP have just stayed steadfast in Gillam. They have to have some form of proof they are still out there.
I think the concern is twofold. If they are in the woods, the suspects are likely in trouble in terms of disorientation, dehydration, fatigue and exposure, secondly, Gillam surrounding area is that last known sighting of them. Police have to rule out that they are lost in the woods. They will keep searching that area until they have a reason to move the search to another area.
