I went to the Kaufman County Murder thread on Websleuths and found one of my posts from 4 days after the murders:
I had found a website that detailed some of the corruption in Kaufman County and named the DA's killer, Eric Williams, before he was arrested. (Williams was arrested two weeks later). It was pretty clear who killed the Kaufman County DA.
In the case of RFG, however, it's been over nine years since he's disappeared and there's nothing that points to foul play: no body, no crime scene, no motive, no suspect. No one seems willing to offer possible theories beyond "he could have been a victim of foul play." Sure, he could have been a victim of foul play. He also could have fallen, accidently, into the river when he was disposing of his hard drive. It just isn't very likely.
I'm not completely dismissing foul play. In fact, I would like to see more discussion on foul play, more theories, with possible suspects and motives. I want to keep an open mind but I need something to work with.
