This is what I have been mulling over since day one before he, Bryan, was deemed the suspect. Why them-(the victims)? I have so many theories and at the end of the day, primarily because of a lack of evidence that may shed further light on a motive or connection, have no clue. Did these pretty girls slight him, mock him if they had a run-in with him in some venue, public or not? Is he just a born-again serial killer who targeted them? Is there in fact, which has been alluded to, a connection between the killer and one or more of the victims? So many questions regarding motive and connection, or lack thereof, to these 4 victims. I think the probable cause affidavit may possibly, probably, and hopefully, shed more light on this. In the meantime, I am of the mindset that he, as the FBI profiler said in a video posted above by another websleuther, saw these girls as vibrant pretty, and so on and was jealous of everything he could not be nor have. (my words and interpretation). Right now, given his interest and studies and history of pursuing criminology, I am voting for "he is just a cold-blooded killer and targeted them" for whatever lame reason. Someone, some, were going to be his victim at some point in time. He is a killer, for whatever reason, if indeed he is convicted.
