  • “Stress made me do terrible things.” (53:18)
  • “I know I was short tempered and cruel sometimes to her and she left with a bit of help.” (1:23:06)
• Investigators interpreted entries as possible confessions or indications of a disturbed mental state, while Kathleen insisted they were expressions of grief and self-criticism.

9. Police Interviews and Surveillance

• Explained diary entries as manifestations of guilt, frustration, and feelings of inadequacy—not an admission of harm.
