Aww one comment made me tear up a little.

It's really interesting that he seems to be referencing the murder indirectly quite a bit. His friend TK helps to run the page. I wonder if becoming friends with someone who is actively involved in a missing person case is having some effect on him? I just wonder what it is like for him to follow the efforts of a family trying find their daughter when someone in his family (IMO) most likely killed his sister. Does he see the contrast in behavior?
He has indirectly referenced the murder about 4-5 times in the past month on FB. There was absolutely nothing (not even about Boulder) about the case on his page for years. I wonder what has caused this? Is it possible that the news about the GJ is having some effect on him? Like maybe he convinced himself that it was a complete accident..and then he heard that GJ wanted to charge his parents with child abuse leading to death?
