Yeah but I bet in hindsight, many family members can see things. Maybe not that would have said they were serial killers but I believe there was almost always thoughts of what is he doing, what is he hiding in that locked shed, why is he so private, where was he... Is he cheating? I know he's cheating...
Seemingly normal lives is the key phrase you say. At minimum none of those things are a normal healthy relationship. And that's just cheating, hiding things, lying and one can't account for where they are or they do and are caught in it on occasion.
In a bit of turn of subject on that, we don't know much yet, but I don't think this family was likely even seemingly normal.. That's just my initial impression and it may not be fair as we do NOT know much but the comic book thing, the gun thing, I think it was Dungeons and Dragons or some such with the daughter. Forget the daughter even, these are two OLDER people and they aren't as far as we know but COULD BE grandparents. A hobby is one thing and at a younger age for sure but an addiction or obsession with it or a lifestyle is another and that's the hints I get. Maybe I'm wrong, again not much is known. A cluttered uncared for home but a professional career wearing suits... Maybe I'm wrong, I mean I'd have never suspected their kitchen. And don't get me wrong, the home is n't falling down and I know myself that life circumstances can stop one from keeping one up the way they'd like, no money for repairs, improvements, etc. BUT other properties were purchased and money spent on offices and prostitutes, etc. so there was money... There WERE things wrong in this family.
Apparently as far as we know the daughter never left home. She was working for dad at the end here. She never drove until recently getting a license. I had a sister who didn't until years after high school so I get it and all these things can be normal BUT not put all together.
Can ANYONE think of a case at all of murder where the wife's hairs were found? Not the daughter's. Much less a serial killer. ANY case. And more of them than of the suspect's? In multiple murders/victims. I think they found one in Vallow said to be Lori's didn't they? On the tape or something? ONE. We've seen cases with animal hairs. But they also aren't found on a belt buckle.
I'm wandering so I'll stop. Little time and catching up and all sorts of thoughts.
