Anna Maria Wilson Murdered by Caitlin Armstrong, Austin, Texas, United States
This source-based behavioral analysis does not establish a clinical diagnosis, motive, or legal finding.
The source presents a relationship-centered homicide pathway involving a former cohabiting couple, a new romantic connection, reported jealousy, monitoring, firearm access, and alleged post-incident evasion. The behavioral analysis is source-grounded and does not constitute a clinical diagnosis or independent determination of motive. Armstrong's reported conduct is discussed in light of the conviction reported by the source, while uncertainties and secondhand accounts remain relevant.
Armstrong and Strickland reportedly met through dating applications, lived together, shared a business, and later ended their romantic relationship while remaining connected. Strickland then began spending time with Wilson, whom he reportedly viewed as a possible new partner. The source describes Armstrong as highly jealous, monitoring communications and location information, and allegedly reacting strongly to the new connection.
The reported pathway moved from relationship transition and jealousy to monitoring, alleged threats, a fatal shooting, scene concealment, and international evasion. The source does not establish every psychological process or the exact internal reasoning of any participant.
Each entry separates the reported behavior or state from the analytical strength of the available narration.
| Behavior / construct | Person / subject | Detailed case context | Evidence |
|---|---|---|---|
| Jealousy Emotional state | Caitlin Armstrong Offender |
The source places jealousy at the center of the reported relationship conflict. The behavior described was not limited to a single reaction; it reportedly included restrictions on phone contacts and distress about a specific perceived rival. This supports a narrative of relationship-threat sensitivity, but does not independently prove why the homicide occurred. Context or trigger: Strickland's reported contact and emerging relationship with Wilson after his romantic separation from Armstrong. Reported expression: Strickland reportedly described Armstrong as extremely jealous and said she restricted how other women's names could be saved in his phone. A friend later reportedly said Armstrong was upset about Strickland going out with Wilson. |
Explicitly reported Confidence: High |
| Possessiveness or monitoring Control dynamics | Caitlin Armstrong Offender |
The reported access to communications and location data suggests intrusive monitoring within the former relationship. The behavior could have provided Armstrong with detailed knowledge of Strickland's movements and contacts. The source does not establish whether every account access was authorized or when each monitoring behavior occurred. Context or trigger: Strickland's social and romantic contacts and Wilson's activities as a cyclist. Reported expression: The source reports access to Strickland's email, messages, Instagram account, and an athlete-location application, along with restrictions on saving other women's names. |
Narrative-supported psychological state Confidence: Moderate |
| Separation or abandonment threat Loss or threat | Caitlin Armstrong Offender |
The transition from romantic partners to cohabitants reportedly left the relationship structurally connected but romantically changed. Strickland's new attachment may have intensified the significance of the separation for Armstrong, according to the source's account. This is a relationship-stressor interpretation, not a clinical conclusion. Context or trigger: The reported end of Armstrong and Strickland's romantic relationship while they continued to live together and work together. Reported expression: The source says their romantic relationship cooled, they slept separately, and Strickland later began exploring a relationship with Wilson. |
Narrative-supported psychological state Confidence: Moderate |
| Chronic interpersonal conflict Relationship stressor | Caitlin Armstrong and Colin Strickland |
The relationship reportedly remained highly interconnected after the romantic bond ended. Shared housing, business support, and ongoing contact may have maintained opportunities for conflict and information access. The source does not document a complete history of arguments or prior violence. Context or trigger: Long-term cohabitation, shared business interests, romantic separation, and reported jealousy. Reported expression: The source describes continued housing and business ties after the romantic relationship ended, together with reported conflict over Strickland's contact with women. |
Narrative-supported psychological state Confidence: Moderate |
| Infidelity or competing attachment Relationship stressor | Colin Strickland and Anna Maria Wilson |
The source describes a competing attachment emerging during an unresolved relationship transition. It characterizes the connection with Wilson as new rather than an established affair, while Armstrong reportedly perceived it as threatening. The exact status of all relationships at the time is not fully documented. Context or trigger: Strickland's reported romantic separation from Armstrong and new time spent with Wilson. Reported expression: Strickland and Wilson reportedly went swimming and to dinner together and discussed spending one or two months together before formally starting a relationship. |
Explicitly reported Confidence: Moderate |
| Emotional escalation Escalation | Caitlin Armstrong Offender |
The reported change in presentation occurred when questioning shifted from general knowledge of the death to a direct connection between Armstrong and the scene. This suggests situational emotional escalation under investigative pressure. It cannot, by itself, establish deception or responsibility. Context or trigger: Police questioning about the vehicle seen near the crime scene and questions about her location. Reported expression: The source reports that Armstrong was initially calm but became increasingly angry when police connected her vehicle to the scene and continued questioning her. |
Explicitly reported Confidence: Moderate |
| Premeditation and planning Planning or impulsivity | Caitlin Armstrong Offender |
The combination of reported preparatory and post-incident behaviors is consistent with deliberate action rather than a purely spontaneous event. The reported evidence includes both the alleged attack method and later efforts to avoid detection. This observation is based on the source's reconstruction and the reported conviction, not independent review of the case file. Context or trigger: The reported use of a firearm, vehicle movement, discarded bicycle, and later travel and identity changes. Reported expression: The source reports a firearm match, a vehicle near the apartment, attempted scene staging, departure from Austin, use of another name, altered appearance, and travel to Costa Rica. |
Analytical inference Confidence: Moderate |
| Deception or concealment Behavioral pattern | Caitlin Armstrong Offender |
These reported behaviors indicate concealment and identity-management efforts after the incident. They were directed toward reducing recognition and complicating police efforts to locate her. The source does not provide Armstrong's explanation for these actions. Context or trigger: The reported aftermath of Wilson's death and the international search. Reported expression: The source reports that Armstrong allegedly moved Wilson's bicycle, changed her name and appearance, and used travel documentation associated with her sister. |
Narrative-supported psychological state Confidence: High |
| Staging or evidence concealment Post-offense behavior | Caitlin Armstrong Offender |
The reported placement of the bicycle was interpreted by investigators as an effort to create a misleading robbery narrative. The source links that interpretation to physical evidence and the lack of disorder inside the apartment. The exact intent behind moving the bicycle remains a source-reported allegation. Context or trigger: The absence of a clear robbery and the bicycle being found away from the apartment. Reported expression: The source alleges that Wilson's bicycle was thrown into bushes to make the scene appear connected to theft, while DNA was reportedly found on the bicycle. |
Narrative-supported psychological state Confidence: Moderate |
| Detection avoidance or evasion Post-offense behavior | Caitlin Armstrong Offender |
The reported flight involved geographic movement, identity changes, appearance changes, and concealment from investigators. These actions made identification difficult and prolonged the search. The source presents them as evasion behavior, while the legal significance is addressed separately through the reported conviction. Context or trigger: The issuance of an arrest warrant after the reported threat and vehicle evidence. Reported expression: Armstrong reportedly left Austin, traveled to Costa Rica, stayed in or was reported near hostels, used another name, altered her appearance, and evaded repeated searches. |
Explicitly reported Confidence: High |
| Emotional abuse Control dynamics | Caitlin Armstrong and Colin Strickland |
If accurately reported, the restriction on ordinary contact labeling reflects controlling and emotionally harmful relationship behavior. It may have reduced transparency around Strickland's communications while preserving Armstrong's oversight. The source gives only Strickland's account and does not establish frequency or broader impact. Context or trigger: Reported restrictions on Strickland's phone contacts during their romantic relationship. Reported expression: Strickland reportedly said Armstrong would not allow him to save other women's names normally in his phone and that he used an alternate name for Wilson. |
Narrative-supported psychological state Confidence: Moderate |

The source reports that Armstrong and Strickland met through dating applications, spent substantial time together, bought a house, and lived together. Their shared home and business created continuing interdependence even after the romantic relationship changed.
By the source's account, the romantic relationship had cooled by 2021. The pair reportedly slept separately and described themselves as friends, but remained connected through housing and business.
Strickland and Wilson reportedly spent an evening swimming and dining together and discussed spending more time together before formally beginning a relationship. This new connection became the reported focal point of Armstrong's jealousy.
The source reports restrictions on Strickland's phone contacts and later access to his online accounts and athlete-location information. These behaviors are presented as signs of close monitoring during a period of relationship uncertainty.
A friend reportedly told police that Armstrong had said she would kill Wilson. Later that evening, Wilson was found fatally shot in the apartment, with doorbell audio reportedly capturing screams and gunshots.
After the killing, the source reports that Armstrong left Austin, traveled internationally, changed her name and appearance, and avoided detection in Costa Rica. She was later identified through a yoga-instructor meeting arranged by investigators.
Armstrong was reportedly arrested in Costa Rica on June 29, 2022, returned to the United States, tried in November 2023, convicted of Wilson's murder, and sentenced to 90 years in prison. This is the reported legal outcome, not a psychological conclusion.
