Just popping in to echo everyone else's sentiments. We all wish there could still be more movement in this case, and more details to come out, and it feels like it's now or never this year. I'm ever the patron saint of lost causes, so I refuse to abandon all hope, but that hope is dwindling rapidly!
It feels hopeless, but it's worth remembering that there have actually been some positive steps recently- just not in the way or as far as we all hope. For example, the likes of Kolar, the CBS team, Steve Thomas, Judith Phillips- all speaking out to a certain extent, and at least finally giving us confirmation of who they believe is JB's killer- BR.
From this, we also now know of the family's involvement in the coverup, and some possible reasons why, and we also know about the depressing political shenanigans that have gone on. The intruder theory has also been discredited. We also have a rough timeline of events, some evidence tying family members to certain things (such as BR with the pineapple and being up in the night, PR and the ransom note, etc)
As SuperDave recently made a very good point about, there is lots of evidence in this case, but unfortunately it's mostly circumstantial. It's almost impossible to tie things down to a certain family member, let alone times and dates, when all 3 family members live in the home together, and are hellbent on covering for each other. For these reasons, I can't see any sane prosecutor or politician taking the case on now, and therefore can't see JR or BR having to testify in court.
There are many cases where there are no outside witnesses and the evidence is largely circumstantial, and some of them do still achieve successful prosecutions, but it is certainly much harder to prove anything. It is possible to infer what most likely happened through circumstantial evidence, but it's much harder to overcome the issue of reasonable doubt.
In my humble opinion, there are several things left that would make a real difference to getting more answers- the case being declared officially closed and the entire case files being opened; the family's complete medical records being unsealed (if they even still exist); the knot in the garotte being untied and tested for dna (again, if anyone even still has it), to tell us who made the garotte and therefore performed the strangulation; and finally, people feeling free to speak out, including Holly Smith who was there at the scene. The big problem, is that I personally can't see any of those things happening, either!
As many are saying, frustrating though it is, we probably have to accept the things we do now know, and also the many things we still don't, and likely never will.
