This is essentially what I said to my husband some days ago. Nobody seems to want to talk about those alleged assault charges in Laci's past.....charges that reportedly came from her decking a girl in a fight over a boy. Granted, it happened when she was in high school, but it still speaks to what kind of a person she was and how she behaved in male/female relationships. Before I get attacked for "blaming the victim," let me point out that I am NOT blaming Laci for what happened her. I am simply agreeing with Yeti's "birds of a feather" assessment and pointing out that we already have some evidence that it may be valid.
What I sort of suspect is that Laci knew her marriage was in trouble, that Scott was a cheater and thought a baby would help her hold on to him, that maybe he'd start to care about her if they had a baby. I doubt he only started having affairs one month before he killed her.
