Yeah, this has been discussed. 128 threads with 60, 70, or 80 pages each, just about every speculative thought and idea imaginable has been tossed about There appear to be several camps. One is the Serial Killer camp. BG knows the area, cases the area, maybe hangs out there from time to time, the girls were just in the wrong place at the wrong time. Another is the stalking idea. The girls were in some kind of online conversation with the perp, or somebody that knew the perp. They were baited in to going to the bridge that day. Yet another is the idea that the girls stumbled upon some information that would be brutally detrimental to the killer. Someone in 'high' standing in the community perhaps. Hence, he murdered, or had them murdered, to save face. Another is that the girls were simply out for that adventurous walk, and stumbled upon some criminal activity right then and there, leading to them becoming victims, so as to cover up the speculative criminal act. I take LE at their word when they surmise the killer was, or had been, a resident, or very familiar with the Delphi/MHBridge area. Some days I think they were targeted, that a motive exists, be it retribution for a perceived slight, or knowledge of some criminal act/drug related, or knowledge of some important person, such as someone in LE, or a Judge, or Public School official, or Clergyman, having engaged in some nefarious activity. But this theory at times is difficult for me, as it would imply the killer knew the girls were going to be there that day, at that time. At times this avenue of thinking leads me to believe the girls had reason to meet someone at the bridge that day. Which leads me to bounce to the serial killer idea. A murderer who happens to have chosen this particular area due to prior familiarity. Seems plausible. But you see, I have doubts here too, because..... I think BG planted evidence at the crime scene, so as to mislead LE in their investigation. If not that, then it appears someone mislead LE in the beginning, as they went down a road of investigation that appears to have been the wrong path, changing 'direction' after 2 years. Or was it that they went down the wrong investigative path by happenstance, with no particular person causing them to do so? The point is, most ALL speculation one can dream up has been hashed, and re-hashed, over and over, on this site, and myriad others. It is truly an unsolved case that boggles the mind. I am sad for the families of these two girls. It is a tragic thing to be dealt in life. I hope the break comes that leads directly to the person, or persons, that murdered these innocent girls.
