I had a quick look around on public records and couldn't locate any criminal record for TS...I just find it hard to believe that someone without a violent history (recorded atleast) would have the forward thinking to argue with someone, call LE, assualt/murder someone, hide evidence and or a body..Because even though the police may have not knocked on her or his door, he knew they would be coming back regardless and would have had to be prepared. I also think to imply that there is a LE coverup is a little extreme. In a small town like that people know people and things get out even if you don't want them to.
I strongly believe that the silence from LE and the lack of media coverage is down to the fact that they either know what has happened or know what hasn't happened.
I believe that if a LE officer was meant to attend that address and didn't, then I think foul play would have been investigated straight away to help clear that officers name. One would think that if a LE officer was involved in something like this, or was negligent in his/her duty that they would be stood down pending investigation into procedure.
Regarding TS, I thought in one of the earlier threads it was determined, and I thought confirmed by a poster who knows him, that TS had a prior assault charge. When I have time, I will see if I can go back and find it.
