I'm not entirely sure but I believe that DG's sister is the mother to AL's (son) children, which would make DG their uncle.
I'm aware of many people who run in the same business circles that have had legal issues, conflict, falling's out and they seem to come full circle and hook-up again. Given that Airdrie and surrounding area (excluding Calgary) is a relatively small town atmosphere, I don't think it would be such a strange thing that they do business together again. I'm not sure how you have determined that there's "no reason" for "AL and DG to do business together...DG has worked as an employee in one of DG's businesses in the past (I will have to try and find the article I had read that in). The patent dispute may not be as big a problem as we have been thinking it is. IMO, I think there's a good chance that they have crossed business paths again, it would be difficult for them not to. What I have seen in both the construction business and the oil & gas industry (from working in them) is that, business is business and everyone is out to make a buck...JMO, when it comes to money, and if one can be of use to the other, there could very well be a smoothing-over of differences. There is no evidence that anyone has mentation that AL and DG definitely did not have contact for the last 7 years. IMO, I like to keep an open mind in order to rake through all possible scenarios here. . I will try and find supporting evidence that AL's(son) children are with PG.
Alvin's son Allen stated that there has been no contact between the accused and the two intended murder victims for the last seven years. I posted the link a few days ago.
I didn't know that the sister of the accused had children ... no need to find a link ... it doesn't seem relevant.
