UPDATE:
I am not finished catching up yet. But figured I would write this out before I forget any of it. I spoke with my brother who finally spoke to local family member more in depth this time than last! Again, take as grain of salt, call it a theory for the sake of no rumors, because we don't know until we know. I am going to relay it like he told me while refraining from my personal opinion or thoughts until later just to keep it clean.
1) Fam member has a few friends with straight connections and within LE. Not all of them will discuss, at all.
2) He told me that he was told that it was actually the LT who was directly involved with the prisoner issue, physically. I pressed him further because I explained the MSM said that the Chief and the officer were both placed on admin leave. He responded that, that officer was already back at work. Meaning LT. He then went on to say that, he was back at work then but they wanted help taking down the Chief. And he too was going to end up retiring.
3) He said his personal life also had complications. It is the same thing we are reading out there. I don't want to write it. Think "Mister"essy" I will leave it at that.
4) He said that fam said it was strange because that day was chaos with the barricades and then absolutely nothing really early next morning. Zero presence. No DNA taken from any employees.
5) The more they learning the more it looks like suicide. The speculation is on the personal matters, the internal matters and the benefits and the hesitation to rule out suicide, which hasn't been done. Said they think that they know what happened.
I hope I am not forgetting anything. I don't want to put "other" conjecture out because it just doesn't fit victim friendly.
EDIT: I forgot one other thing! My brothers friend company was out on that location do work a few weeks before it happened. Removing and clean up. I asked my brother if he asked him if there was any evidence of vandalism and he said they showed him around in building, yes, and told him the same story of issues that we were told at last presser. This was a few weeks before LT was shot.
