I said early on that I could see why no one was coming forward. Most folks want to keep their family, and themselves, alive. This was directed at this family, for a reason. I think that as long as the others mind their own, and don't get into anything over their heads, like the Rs did, then I believe the others in the community feel they'll be fine.
I disagree that JW knew the baby wasn't his. I think they waited to go to AK until after the DNA tests came back to ensure that she wasn't his baby. There were three potential fathers. We know at least two were very much hoping that baby was theirs, one, who turned out to be its' father, and one who pulled its' sock off in the hospital. He was there. He wouldn't have been there if he knew. The Ws may know something but none of them seem like the sharpest knives in the drawer to pull something like this off, unless they are putting on a really good acting job. It seems that the elders were successful, and maybe had some ties to some sketchy stuff, but the elders didn't seem to have a super relationship with their son and dil, at least not one they'd kill forr them over.
I just don't see them killing eight people over custody. Hire someone to make HMR disappear and JW gets S anyway. It's not like LM didn't blurt out custody within 24 hours after the murders, along with the slapping incident, and the cops being snots about something the past weekend. They left the mouthiest one alive, yet, nothing has happened. The Ws may have done this but I don't see them having the money to hire it done, and I don't see the elders as caring that much about what their son wanted. I think they have favorites in the family who are more successful.
We've had the alphabet boys, in town, here, to investigate a case but no one knew that they were here. Well, I did, but they didn't come in town, in marked vehicles and such. It was kept fairly low key, and then they they flew back out to wherever they came from.
I could be wrong. I just lean more toward something that they all had in common. A place.
