Makes sense.So, from 1973 - 1981 we have the TransCanada Highway Murders of which a few were either contemplated or put on the HOT list.
Probing the mystery of Edmonton’s killing fields
Aug 5, 2017
"Homicide count for females in Edmonton
We identified 49 such cases since 1986. Our collection is in no way representative of the larger number of female homicides in Edmonton during the same period, and we may have overlooked relevant cases. Nonetheless, these 49 cases shared striking characteristics."
And Edmonton is the direct route to Prince George and the Highway of Tears. Highway 16 seems to have kicked off in around 1989 and about the same time that the Killing Fields of Edmonton kicked off. It would seem as if these three areas are directly connected and if that is so then we know that he is at least in his late 60's and would have been in his early 20's at the time of Mary Ann's abduction and death. There are too many connections and too many similarities to not believe that this is the same man. Most likely he was born and raised in Edmonton and sometime between 1971 - 1973 he moved which accommodated the travel between BC and Alberta along the southern route and then between 1981 and 1986 he moved back to the Edmonton area where he's been ever since.
A thought- perp attended a university or other training school in BC after graduation, then returned to Edmonton? Confidant on the phone ... actor, salesperson?speculation.
