I honestly don't think the general public, like us, could solve the murders. We simply don't have enough information and facts about the crime. It is difficult to put a psychological profile together because we don't know how the bodies were found, what type weapon was used, or even basic things like who found their bodies (other than conjecture and social media rumors). Speculation against DN being BG is based upon information that we don't have. For instance, DN is known for wielding his hatchet-yet we have no idea if a hatchet was involved. DN has a gun-but we have no idea if a gun was involved. DN has a history of sexual offences-but we have no idea if there was a sexual component to this crime.
I don't think LE ever thought that we, as the general public, could help solve this. I don't think they wanted us to try (their talks about not altering the picture, not doing side-by-side comparisons, etc.) I think the only thing they wanted from the public was for someone who had actual personal information about the perp to come forward and share what they know.
While I have participated in many discussions on crimes that I think CAN be solved (or at least assisted) by the general public like us, I don't think this is one of them. I've been following this case on here not because I thought I could help but because of my personal ties to Delphi. I want to keep up with the updates and it's interesting to hear other people's opinions about what's going on.
