Case Summary
On May 11, 2022, Moriah Wilson was found fatally shot in the bathroom of Caitlin Cash's Austin home after returning from an outing with her former romantic partner, Colin Strickland. Investigators initially considered robbery because Wilson's expensive racing bicycle was missing, but surveillance, cell-phone data, vehicle evidence, witness accounts, and ballistic analysis redirected the investigation toward Strickland's then-partner, Kaitlin Armstrong. Armstrong left the United States using a fraudulent passport, was later arrested in Costa Rica, and was convicted of first-degree murder on November 16, 2023, receiving a 90-year sentence.

AI Intelligence Assessment
Relationship Pattern
Romantic Triangle
Pattern Analysis
The source describes a relationship triangle involving Strickland, Armstrong, and Wilson. Strickland and Armstrong temporarily separated, during which he had a month-long affair with Wilson, then resumed contact with Armstrong while remaining connected to Wilson. The reported jealousy, concealed communications, vehicle surveillance, firearm access, and subsequent flight are presented as important parts of the investigative pathway, although the source's behavioral conclusions should be distinguished from proven facts.
Investigative Notes
Police initially considered a robbery involving Wilson's expensive racing bicycle and located the bicycle discarded nearby. Shell casings, surveillance footage, a black Jeep, cell-phone data, witness accounts, and ballistic analysis later became central evidence. Cash's gunshot-residue test was reported as negative. Strickland was initially a person of interest but was later reported cleared by phone data and timeline evidence. Armstrong was questioned after an unrelated warrant failed because of an incorrect date of birth and left the station after requesting an attorney. The source reports that she left for Costa Rica using her sister's passport, was located through a social-media contact, arrested, returned to the United States, and later attempted to flee from a medical appointment in October 2023. She was convicted of first-degree murder on November 16, 2023, and sentenced to 90 years in prison.
Investigation Confusion
The source contains repeated name inconsistencies, calling Wilson Anna, Mariah, and Anna Mo, and calling Armstrong Caitlyn, Kaitlin, or Caitlyn Armstrong. It also says Armstrong was charged with attempted murder before later describing a first-degree murder conviction, which is internally inconsistent. Early investigators considered robbery, briefly focused on Cash and Strickland, and had difficulty identifying the driver of the black Jeep because the footage was initially too grainy.
Case Reconstruction / Puzzle Pieces
Wilson spent the day with former partner Colin Strickland, including swimming and a stop at a nearby cafe, before he dropped her at Cash's Austin residence. Cash later returned and found Wilson fatally shot. The missing racing bicycle initially suggested robbery, but it was found discarded nearby. CCTV and doorbell audio placed a black Jeep near the residence around the shooting, and investigators connected that vehicle to Kaitlin Armstrong. Relationship history showed that Strickland and Armstrong had separated, that he had a month-long affair with Wilson, and that he remained in contact with Wilson after resuming the relationship with Armstrong. Phone-location data reportedly placed Strickland leaving before the shooting and showed Armstrong's vehicle following the route toward the residence. The source further reports that ballistic analysis connected the firearm to the shell casings, while Armstrong's flight and later concealment efforts became additional post-incident investigative developments.
Risk Assessment
The reported risk indicators included a recent relationship rupture, an overlapping romantic attachment, jealousy, concealed phone contact, access to a firearm, alleged surveillance or stalking, and later identity concealment and flight. These factors were associated with elevated investigative concern, but they do not independently establish criminal responsibility or psychological diagnosis.
Key Takeaways
The case illustrates how an apparent property-motivated crime can be redirected by relationship history, surveillance, digital-location data, and forensic evidence. Relevant warning indicators included concealed communications, jealousy surrounding a romantic rival, recent separation, firearm access, possible monitoring, and post-incident evasion. The source also demonstrates the importance of separating early investigative theories from later evidence and of preserving uncertainty where the report is internally inconsistent.
AI Case Q&A
What early signals mattered most?
The most important reported early signals were the prior affair between Strickland and Wilson, Armstrong's reported jealousy, Wilson's concealed contact name in Strickland's phone, the unexplained black Jeep near the residence, and Armstrong's unaccounted-for movements.
Which clues helped connect the case?
The case was reportedly connected through the discarded bicycle, shell casings, CCTV and doorbell-camera footage, the Jeep associated with Armstrong, cell-phone location data, Strickland's timeline, the relationship history, and ballistic analysis.
Which evidence types appeared strongest?
The source presents ballistic analysis matching the firearm to the shell casings, surveillance footage, cell-phone data, doorbell-camera audio, vehicle records, witness accounts, and digital travel records as the strongest evidence types. The precise evidentiary record and legal rulings are not independently available in the supplied material.
Witness / Eyewitness Statements
Caitlin Cash reportedly told 911 that she found Wilson unresponsive on the bathroom floor and later said Wilson had been with Colin Strickland and planned to swim with him. Strickland told investigators about his relationship with Armstrong, his prior affair with Wilson, Armstrong's jealousy, and his purchase of a gun for her. A neighbor's doorbell camera reportedly captured Wilson screaming. Police interviewers and investigators described the vehicle, timeline, and relationship evidence; no other direct eyewitness account of the shooting was reported.
How did follow-up reports change the understanding?
Follow-up investigation changed the working theory from a possible robbery to a relationship-linked homicide. Investigators initially focused on Cash and Strickland, then connected Armstrong to the Jeep, the relationship conflict, the firearm evidence, and the digital timeline. Later reports described Armstrong's international flight, arrest, escape attempt, conviction, and sentence.
What remained unclear?
The supplied report does not provide a complete forensic reconstruction of the shooting, the exact number of shots, the full chain of custody for all evidence, or a detailed account of the defense position. It also contains inconsistent names and an inconsistent description of the initial charge. The source's assertions about stalking, obsessive behavior, and the meaning of body language should be treated as allegations or commentary rather than clinical or legal findings.
