Word association is just that. If I read a different book than you have, then perhaps I associate a case completely different with even more word association tangles than you have. It doesn't matter though, because the world is primarily cause and effect, and the words on printed page won't have an effect on the mind of a killer, if he hasn't read said book, or his sexual urges simply take over the rational mind at a time he is driving past a woman alone with no witnesses around.
The serial killer isn't an empty vessel waiting to be programmed. It isn't even a small percentage of killers that plan their murders based on word association from a book, movie, comic book or novel. It might help one's understanding of male sexual urges if they were, in fact, male. No book written in the 1800's that has a character with a similar name of a street that a killer drove on, even remotely plays a part in when the urge comes, or the location of a vulnerable victim.
Like every human, serial killers are one part genetic makeup, and one part life experience. Any combination of the two create the whole... and like most humans, that imprint comes very early and usually lasts a lifetime. We have yet to discover what mix creates the killer, but I guarantee word association, anagrams, or first syllable word games don't play a significant part.
Pickton didn't wait for his victims to walk down a certain street because it was the same name as a Dickens character. Crime is just as much, if not more, about opportunity as planning... especially to such a degree where word association overpowers the primal urge for sex and murder. After 2 hours of driving around looking for a hitchiker, the Serial Killer won't pass by a victim because she is not wearing the same pant suit as his favorite Abba singer.
