Katja Obinger locates Beth Childs and convinces her to look for clones in (Canada, I presume), based on the fact that a number of Eurpean clones had been murdered. How did Katja know about the murders? Where did her information come from? Most importantly, was she acquianted with any of the European clones before their untimely deaths?
It seems from the show that Beth was the first or only clone Katja had direct contact with, but in that case, how did she come by the case files of the other clones? In particular since they are all of different nationalities.
