I think the Wagners was afraid to do it legally when HR was alive, going to court to get custody would had exposed the underage sex before now. If HR just sign her over to them, then it wouldn't had been a big legal issue. I also, think Jake may have been satisfy with the way they did a week on and a week off, but Angela wanted SW to raise because she didn't have any girls of her own.... I think the custody issue was more Angela than anyone else. IMO
I don't think that at all. I don't think it was AW. I think it was Jake all the way. Taking SW was a way to hurt HR for dumping him and having another man's child. No different than thousands of other partners in a relationship that use the kids to get back at the one who left.
When she wouldn't sign over her rights, and her dad wouldn't let him beat her into submission, he just killed her whole family. Just like many, many other domestic violence crimes where the partner kills the spouse and kids and sometimes parents and extended family of the other partner.
