If I recall correctly it was someone who was going to say Scott's and Laci's marriage was on the rocks and they were going to get a divorce after the baby was born.
But that's just stupid of them to try to prove that, whether or not there was any truth in it. All it does is provide motive.
WHEN does all this "domestic violence against women" usually take place? Not as much while they're together, as while they're divorced or divorcing!
