Looks like they had to edit this together quickly to make a deadline without any continuity or comprehensive story.
Andrea's son Kevin suddenly does a 180° turn and now believes Chris is guilty. The first hour he supported Chris being innocent. Why? Kevin even said "If Chris is involved then I don't understand the motive."
Is Chris guilty or so susceptible, he will confess to anything? He pauses during questioning, allows himself to be approached and constantly interrogated. He has no confidence or self-defense.
He should have hired a lawyer long ago when cops kept accusing him. Why does he give in and keep talking to strangers coming to his house instead of telling them to leave?
Why are the police so friendly to a serial killer? I realize they want information, but they are so nice to this brutal, sadistic pig, it's sickening. After they were so aggressive to Chris.
Josh Mankiewicz should have explained to viewers:
1. How vulnerable and weak Chris is so we understand his behavior.
2. What caused the stepson to change and suspect Chris.
Mankiewicz should have given us a hint or a clue of what happened. This episode is so convoluted and the story unsupported, even the juror was confused and that led to their verdict.
