I am not sure if facial recognition software will be useful in this case. Police already know who everybody is, with the exception of the Night Walker. Even if they can digitally scan the pictures that exist of him, what will they compare it to?
They could compare it with the Passport photos of all Canadians, which are already on file. As well they could compare it with passport photos of all people who arrived or left Canada, through border crossings a year before or after the Sherman's deaths. (Assuming that that the Border crossings retain the photos). Of course there may be Privacy issues, and Charter issues in doing such a broad search. If law enforcement needs a court order from a judge to do this, how could they convince the judge, that comparing millions of photos to the Night Walker is just not a 'fishing excursion'.
On the surface it looks like a huge amount of computer processing and human management of the process would be required. Does law enforcement have the budget for a project such as this?
I think law enforcement should try to do it, but there will be roadblocks. The biggest one, is the ability to get a good scan from the pictures that the TPS has of the Night Walker.
If the Night Walker crossed illegally in and out of Canada, there will be no passport records to compare.
