The idea that there were thousands of photos that were too disturbing for the public to view combined with the fact that a select few were released, may suggest that many of the unidentified women seen in the photos are likely to be already known as deceased by the police.
It therefore becomes more a matter of identification, rather than trying to decipher each woman's individual fate.
In other words, it's likely that the fate of some of the women caught in the photographs that have been released to the public, may already appear as deceased in other photographs that have not been released.
It would be interesting to determine how many women from all of the photos released to the public, have actually been proven to NOT be deceased.
It would then be a case of separating the women into different categories; those confirmed definitively to have NOT been one of his victims, and those who remain unaccounted for.
