I don't believe I had heard about this before. If I did, it didn't grab my atttn. From what I have heard about that sister, I am wondering why she didn't get temporary custody of the little girl. It seems to me, one of her favorite pastimes is sticking her nose in everybody else's business. SIL, other members of husband's family, etc. I could be wrong, but from what little I've read, I get the opinion she would be considered the family troublemaker : at least on her in-laws side of the family. It also strikes me as being a little odd that during the early days after the murders and before the funerals, we never heard one word from her concerning her loss, her theories, her thoughts, nothing. Almost like she didn't even exist! I know hec reminded us we can't judge a book by its cover, but I would be scared out of my wits to be in the same room with her!
Also, I can't imagine a family of eight would be murdered over a great niece and a second cousin. I have no brothers or sisters, but if somebody was interfering with my first cousin's granddaughter, I don't believe I would be in danger unless I was trying to get custody of the little girl. And then I think that the parents would be relieved for the girl to remain in the family.
Like I said before, everything concerning this case has been bizarre since the first news report broke, and I think the reasoning behind the murders, as well as the identity of the killers will also be bizarre...
