My suspicions are centered mainly on the interest that LE has shown in the home and the home surrounding. If it happened I think it went down this way My theory? Momma and all the kids were asleep. Maybe Momma had had a glass of wine and maybe not. Lisa woke up that night and kept crying. That woke up the youngest boy. Momma was tired, half asleep and upset that her crying was getting the boys up. Something happened maybe not intended, more like a loss of control. Momma sent youngest boy to bed and he ended up in her bed. She contacted someone (friend, relative) to come help. Scene was staged, at least the window was. Friend/relative took Lisa away and Momma cleaned up at home. Last minute thought was that info was on the cellphones and in a panic/without thinking about it those had to go too. Cells may have gone with Lisa or may have gone later. Friend/relative left, Momma went to bed and pretended to be asleep until Daddy came home. Probably hugging the little boy. Or Momma was still up when Daddy came home and ran to the bed so she could pretend to be asleep. At that time I don't think Daddy really knew what was up. Though by now he would at least have to have some suspicions because I am sure LE filled him in with what they suspect happened. ETA: It is not that I don't think the parents loved Lisa. I think they did love Lisa very much. And I think that is what was showing in the inital interviews (esp DB.) I think the tears were from real grief, and fear for herself, love for the baby and remorse for what happened.
