I don't know. I am inclined to keep victims like her on the list in the absence of proof otherwise. And the problem of course is that a killer might mutilate a tattoo to hinder identification not for fetishistic/ritualistic purposes.
Dr. Tumosa and we have the notion that the Gilgo 4 represent LISK's very own private cemetery. He controlled who got in, and how they got in. Controlled the status of their remains etc etc.
Does LISK's interest/disdain for tattoos have some sort of warped religious angle to it? For example, SOME Orthodox Jews believe you should not be buried in an Orthodox cemetery if you are tattooed. And other Orthodox burial societies have a sort of "don't ask don't tell" approach. Muslims also frown on it but believe tattoos that were done before conversion are wiped clean by the act of converting. Does LISK "cleanse" his victims in some way in his f'ed up mind?
Just some things to consider.
