Key Discussion Points & Insights
1. Reconstructing the Murder Timeline
[03:06]
- Review begins with the night of May 11, 2022, when Mo Wilson was found dead.

- Police start zeroing in on Armstrong after exonerating Strickland, Wilson's former lover.
Quote:
“It was odd how much Kaitlin knew about the murder — where Mo died and how she died. Despite police not releasing those details yet, Caitlyn's comments were extremely suspicious.” — Katie Ring [03:33]
2. Police Tactics & Early Breaks
[04:10]
- Armstrong was brought in on an old theft charge (unpaid Botox from 2018) as a pretext to search her home and phones.

- She sells her black Jeep for $12,200 and proceeds to the airport, fleeing first to her sister’s house in upstate New York.
