These people consider a reward as being free from scrutiny of the public and police and just being free in general. That’s there idea of a reward, and the perps consider being feared as the ultimate reward. A few coins won’t loosen there tongues, it’s more likely one of them will get caught up in a moment of self congratulations one day and say too much. It’s all about how that happens and who’s listening but that’s ultimately how they will get caught IMO.
Killing someone isn’t complicated. Getting rid of a body quickly is though. Like I said it’s much harder for one person to do that and not slip up without help in how and where to do it, especially if they are not particularly skilled in doing it. They had not more than a few days before the police was already looking so not much time.
Doesn’t sound like the work of one person but the killing was almost definitely just one person but they had help to clean it up. The trail is too clean for nothing to have come of it. I compared it to Libby Squires case because look at how much evidence is present when only one person is involved. One person can’t think of everything and it shows.
