What convinced me was the Amber Frey testimony.
It was not just the fact that he was cheating, it was his manner, his behavior and attitude about his missing wife.
I heard the tapes and read the transcripts. The fact that he was completely detached from Laci and the baby ... He said things like "Laci and HER baby" or "Laci and THE baby."
He never acknowledged the baby as his. For God's sake he
was on his way to the volunteer center to "look" for Laci but decided to pull over for an hour and talk to Amber.
It seemed to me he was in no hurry to find her because he knew where she was.
And frankly his courtroom behavior was very odd as well, smiling, joking ...?
I am no psychiatrist, but he strikes me as a sociopath who has no geniune human emotions.
