Have you analysed the exact timing of Isabella's call with Dr. P.S.? Check the Record of Communications for precise timestamps.

How does the timing of this call align with the reported time of the gunshot at 21:15? Could Isabella have been occupied during the critical moments?

Is there any visual evidence that corroborates Isabella's whereabouts during this period? Perhaps the CCTV image provides clues.

What does the pattern of calls between Isabella and Dr. Stanford suggest about their relationship and the nature of their communication?

The Record of Communications shows that Isabella received a call from Dr. Peter Stanford at 21:08, lasting 7 minutes and 42 seconds, ending just after 21:15, the reported time of the gunshot. This suggests that Isabella was on the phone during the critical moments. The sticky note on the Private Investigator's bulletin board ("I.H set call 21:00") indicates that this call was scheduled in advance, supporting the idea that it was a routine or planned conversation. Additionally, the CCTV image taken at 21:06 captures someone resembling Isabella outside with her phone in hand, possibly awaiting the call. The earlier call from Dr. Stanford at 18:14 suggests regular mental well-being checks. This consistent communication and the timing of the call provide strong evidence for Isabella's alibi, implying she was occupied during the time of the incident.
