I’m wondering if someone suspects they know who BG is, but they won’t come forward out of fear of what he may do to himself. Perhaps they suspect someone who has threatened suicide in the past, and they fear it may push the person over the edge. I could see being hesitant to come forward in this case, especially if the individual is someone they genuinely care about and even more so if they aren’t sure he is BG.
That being said, if BG has made threats of suicide I suspect it’s mostly an attempt at manipulating those around him. That’s not to say he isn’t capable of carrying it out, but my thinking is that if we are dealing with someone who kills two random, innocent girls then we are looking at a person who is going to turn his anger outward, not on himself. If he is a sociopath, he’s probably going to use manipulation to get what he wants from people, so it doesn’t seem totally out there that he would threaten suicide to the people around him to keep them quiet.
