Some of this seems kinda fishy. I don't know much about bankruptcy but I do know that, with poor choices when we were younger, credit can effect being able to buy houses and such. I have kinda been wondering (since I read the timeline) how they have their Calgary home (which seems to give the air of being well off), a new house in Edmonton, and the property in Mexico (I know that hasn't been confirmed as theirs) but even just to afford to go to Mexico for a short holiday let alone an extended period of time would cost as well. I mean no disrespect to the family but in DG's eyes, this could very well make them seem like they should be able to of compensated for this help on the patent. Even if it was acknowledgement that he was after, he could see them as not giving him what he thinks his help was worth... and fueled the anger.
Also in regards to DG's parents. I was under the impression they were in their 80's. I don't know many, if any, 80 year olds that go camping, especially for any extended amount of time. No matter how fit, involved in the community they may be I think it is strange that they would be camping. (maybe just me but if the RCMP don't even know if they have returned home do they even know where they are?) We have heard nothing about his parents. Does anyone know their names? And as far as comments on them knowing about his criminal activities, such as the meth lab, I believe they were either afraid of him or else they truly didn't know what was going on. I think most parents can be very easily deceived by only seeing what they want to in their children. He sounds like a very smooth talker and would be able to convince them that nothing is wrong, or he is doing nothing wrong and maybe they just believed him. That they were away the last few weeks, they very well could of not had a clue as to what he was up to. I just really find it odd that if they really are camping, why wouldn't they of ended their camping trip early when they heard this was all happening and come home. Would they really just go on with their holidays if they knew the police were raiding their home (a home they have owned for a lot of their life???) It just seems strange in my opinion...
