You know, just thinking, we're not privy to the suspect's knowledge/thinking, the family's knowledge, and even LE's knowledge, in terms of where to begin to think to look for the bodies. It's really too vast an area and so spread out, where he could have travelled to. He had much time before he was first picked up and arrested, and he may very well have put the bodies in a temporary location so that he could go back to the house and clean up or do whatever he likely did there. There was a report from a neighbour that lived close to the corner and end of the street, that heard what sounded like a speeding truck going around the corner in the early morning hours. And, for his safe-keeping, that temporary location may not have been on the Airdrie acreage per se, but perhaps some reasonable distance from there that he knew of that likely would be safe for a certain period of time.
I believe it's truly like looking for a needle in a haystack in what is most likely a rural, and possibly very remote setting. Thus the importance of people in Calgary, Airdrie and vicinity, to check their properties, especially noting anything that looks unusual or disturbed.
There are many lakes, some small, some larger. Some are probably more recreational this time of year than others, but you know, it makes me even think of where he may have travelled with his family/parents as a youth. For example, did they enjoy camping as a family when DG and PG were younger? We know his parents likely have some kind of trailer or RV to still enjoy camping, because no one can picture 80-year-olds pitching tents, and during the first arrest, we were told his parents had gone camping. They may even have a permanent spot a few hours drive from the Airdrie acreage that they go to from time-to-time. Many of these places have lots of social activities for members and their families: weekly dances, and so forth.
So, there could be any number of spots that DG knows well, or came across at some point, and some probably are not even very frequented areas, and as the loner type, he may have explored further on his own, getting away from where most of the activity would take place. Teenage party spots to be included as someone mentioned in an earlier post, if the area hasn't since become developed.
I mean, there's even the scenario where someone could be building something, and will be pouring concrete (sorry for that visual). There's lots of building going on in and around Airdrie, just looking at the real estate there.
How can we know to what extent he went? Did he just dump the bodies, bury the bodies, burn, dismember, etc.? He is not going to tell anybody anything about the bodies, because he doesn't want them to be found. Unless someone can get through to him - his sister, and/or his parents - and what kind of relationship do they even have with him - we don't know. And then, one would assume he would have to have a conscience - and I'm sorry to say, I don't hold out too much hope there.
Not trying to be negative, just realistic.
LE will probably have a priority list that goes beyond the Airdrie property, just as they mentioned they were going to certain areas in the course of their investigation. And, I suspect, it will be based on information that is not available to us here, and perhaps from the 900 tips that came into them.
If any of his travels can somehow be reconstructed, on how far he may have went - maybe - but I still think it's a very big area to be covered. We really have to hope there's a connection somehow in his thinking to where he decided was the "right spot" to dispose of the bodies.
This would be the time IMO for LE to ask for the public's help in volunteering to cover some of these areas. A freshly dug spot for example is going to be more recognizable as such, sooner, rather than later. Also, to reveal if it's just the green truck that he drove, or if any other vehicle may have been used. That information if they have it, needs to be out there. AL's truck? The black SUV found on the Airdrie property, as examples.
Just my two cents.
