Just because the public was not informed of every single minute detail, it doesn't make it "hinky". My goodness, don't you think LE knows a little more than we do? Maybe they are trying to spare feelings of Rebecca's family?
I think they know a lot we weren't told. I think they should have to explain all the evidence and I do not think they are sparing the feelings of Rebecca's family at all. At least, I do not think that is any motivation for them.
