9. The Trial: Prosecution & Defense
- Prosecution (Lisa Naroda & Karen Kowal):
- Argue that Sabrina would never have acted without Kevin’s manipulation; present evidence of an inappropriate relationship and communications; highlight Kevin’s suspicious financial and emotional responses.
- Defense (Mike Connick):
- Maintains Kevin’s innocence; attacks Sabrina’s credibility as a “seriously disturbed human being”; notes lack of direct evidence (no love letters, photos, or physical evidence of the alleged affair or conspiracy) (39:41–41:00)
- Points out that mandated reporters, including Lisa herself, never reported any inappropriate behavior.
- Challenges reliability of Autumn’s testimony and questions the logical leaps in the prosecution’s narrative.
