What you said gives me an idea--maybe they had this knock-down drag-out fight, in which he punched her, and she had broken ribs, and maybe she did lie down, but was bleeding internally and died. I remember hearing of a case of a child who was kicked. After the scumbag abuser (mother's boyfriend... as IF you couldn't guess) had done that, the fool mother later put him to bed b/c he was very, very tired. Well, he was very, very tired because he was bleeding internally... needless to say, he died.

It is possible that Laci's death was the result of complications from the fight, but Scott's conversations with Amber and his arranging an alibi do make it seem like he was planning her death. Maybe he just got lucky!
