The MOs in those cases were similar to what we know about the September attacks in Tweed. The Tweed-area attacks will probably be mysteriously missing on weekends, except if someone didn't go away/have company.
Moving forward a few years from 1983, I would hope the police will investigate any of the unsolved cases previously attributed to the Scarborough rapist. DNA technology has come a long way in the interim. Paul Bernardo may not have been the only one out there.
It would be prudent to investigate any unsolved missing persons cases/murders involving similar circumstances to Jessica's, too. You know, keys and wallet left on the table, a responsible person missing, male or female.
Why on earth did Blatchford expressly mention Tori Stafford in her article?
I believe that someone, somewhere did have a clue about what was going on. What about military intelligence?
I am still thinking of that female military intelligence officer found dead of "suicide" at Camp Mirage. And the mysterious death of the young student at RMC in Kingston.
This article stands out as a clue to how the military handles unexplained non-combat deaths:
