Then in that case, there are at least three avenues that possibly might bear exploring further although each is as different from the other as can be but all of which are worth tucking under the hat for later consideration imo.
1. Given that we understand major contracts were in hand, or all but so, before the sudden death of WM, for the new MillardAir enterprise, including Boeing and other such major military and commercial contractors, would sleuthing reveal any administration level MillardAire personnel with their own personal connections to such powerful entities? Are there ways in which the removal of MillardAir's chief executive and the defanging of his irksome son might be effected - in the first case because prompt intervention was necessary and in the second because although he seems non-threatening enough, you never know if the youngster could assemble a crew with sufficient expertise to carry on. (What IS the disposition of MillardAir's significant assets?)
2. Still on the MillardAir competition riff, has anyone checked the ownership and principal's background of any other businesses located near the Ancaster Fairgrounds or otherwise near the location where we understand TB was last known to have been that night? Just on the lookout for co-incidences, of course, say anybody else who may be somehow linked to the family. <modsnip> Has this person inserted himself into the story at any point (as in being quoted by MSM)
3. Then, of course, there's that odd ancestry.com posting from somebody in Tillsonburg trying to find a birth father with the name WM. So far as I can tell this is the only post the individual in question has ever made which is odd, in itself, because this genealogical website is quite expensive and, I believe, you have to be a member to post. (At least I hope so. I spend an inordinate amount of time on ancestry.com and I'd hate to find out about freebie posts.) There have been earlier posts about the potential for an abandoned illegitimate son's treachery having played a role here. Anything else down that road?
That's it for now, but there are many more.<modsnip>
