Key Discussion Points & Insights

1. The Final Manhunt and Capture in Costa Rica

• US Marshals’ Investigation: After Kaitlin’s disappearance, US Marshals pursued leads in Santa Teresa, Costa Rica, canvassing yoga studios, reviewing surveillance footage, and posting a Facebook ad for yoga instructors as a ruse to flush her out.
  • “They posted an ad on Facebook seeking a yoga instructor, hoping to lure Caitlin out of hiding. But they still had no luck. What they didn't know was that they had just missed her.” (03:28)
• Plastic Surgery & Identity Change: Armstrong underwent facial surgery and used her sister’s passport under the alias “Allison Page.”
• The Trap is Sprung: After responding to the Marshals’ fake yoga instructor ad, Armstrong was finally identified by federal agents at a hostel, just days after her surgery, betrayed by her appearance and a receipt found during her arrest.
  • “When Fernandez leaned in, he noticed the woman had bloody nostrils and a bandage on her nose. Then he saw her eyes. And at that moment, he knew he was staring into the eyes of Kaitlin Armstrong.” (05:02)

2. Armstrong’s Return and Court Appearances

• Extradition and Public Frenzy: Brought back to Texas, Armstrong faced reporters with stoic silence.
  • “She kept her head down, showed little emotion, and walked past reporters without reacting. For all the running she had done, she was now right back where she started.” (06:07)
• Arraignment and Pre-Trial Behavior: Armstrong pleaded not guilty, showed detachment, and said little, but investigators noted her visible irritation when confronted with evidence of her boyfriend Colin Strickland and Mo’s connection.

3. The Failed Jailhouse Escape

• Escape Plan: In jail, Armstrong grew physically stronger, covertly devising an escape plan.
• Execution & Recapture: Feigning injury, she got herself sent to a medical appointment where, due to her “injured” leg, her cuffs were loosened. Armstrong ran, slipped her restraints, scaled a fence, and led officers on a mile-long chase before being captured after a physical struggle.
  • “Honestly, if this girl hadn't committed such a heinous crime and took the life of an amazing young woman… I would almost be impressed. But despite her efforts, Caitlyn's grand plan had failed once again, and she was back in custody to face the music.” (09:05)
• Aftermath: Facing new felony charges, the escape attempt was cited as evidence of her unwillingness to accept responsibility.

4. The Murder Trial

• Case Built on a Web of Evidence: Prosecutors outlined Armstrong’s months-long jealousy, her digital tracking of Mo, physical surveillance, the matching shell casings, arms training, and Armstrong’s lengths to cover her involvement.
  • “This was not a case built on one dramatic reveal, but on a sequence of actions that, when placed in order, told a coherent story. Jurors were asked to consider the totality, how all of these events aligned with the same narrow window pointing in one direction.” (12:22)
• Testimony Highlights: Emotional testimony from friends, digital evidence (social media, Strava app, video), Colin Strickland’s tense, draining two-day stand.
  • “He said that he thought he had [loved Kaitlin], but also said that he wasn't sure if he actually knew her.” (14:47)
• Defense Arguments: Cast Armstrong as “frustrated, not jealous” and suggested she fled fearing the “real killer.” Armstrong declined to testify.
• Verdict and Sentencing: The jury deliberated just two hours before finding her guilty of first-degree murder. The court, moved by Mo’s family’s statements, handed down a 90-year sentence.

5. Appeals and Civil Fallout

• Appeals: Armstrong pursued appeals on grounds of ineffective representation and an alleged pregnancy, but provided no supporting evidence. All appeals were denied, and the conviction was upheld in January 2026.
• Wrongful Death and Financial Consequences:
  • “In addition to the criminal case… Mariah Wilson's parents filed a wrongful death lawsuit… a Texas court ordered Kaitlin to pay $15 million… including a provision barring her from profiting in any way from Mo’s death.” (18:49)
• Asset Transfers and Further Litigation: Armstrong attempted to move her remaining assets to relatives, prompting another lawsuit from Mo’s family for fraudulent transfer.

6. Legacy of the Case and Reflections

• Impact on Cycling & Community: Mo’s legacy honored through tributes and a foundation supporting education and sports. The cycling world mourned the loss of a rising star.
• Broader Implications: The case highlights the dangers of digital tracking (apps, social media) and the unforeseen ways personal obsession turns lethal.
  • “Fitness apps meant to track progress became roadmaps. Social media interactions that felt casual became evidence of obsession.” (22:30)
• Host’s Closing Advice: A cautionary note to listeners about jealousy, break-ups, and the wisdom of walking away rather than seeking revenge:
  • “If you absolutely want to hurt someone who cheated on you, simply walk away and never talk to them again.” (23:17)
