Psychological & Behavioral Intelligence

This source-based behavioral analysis does not establish a clinical diagnosis, motive, or legal finding.

Case Overview

The source presents a relationship-linked homicide pathway involving separation, overlapping romantic attachments, jealousy, concealed communication, firearm access, alleged monitoring, and post-incident evasion. These observations are behavioral and source-limited; they do not constitute a clinical evaluation and do not independently establish causation or guilt.

Relationship Dynamics

The reported relationship system involved Strickland and Armstrong separating and later resuming their relationship while Strickland maintained a romantic connection with Wilson. The source describes Armstrong as jealous of Wilson and describes hidden contact through a changed phone name. Strickland's account also portrays a physically and emotionally unsettled household, with separate sleeping arrangements and both partners dating or seeing other people during the separation.

Escalation Summary

The reported pathway moved from relationship disruption and competing attachment to concealed communication and jealousy, followed by alleged surveillance, a fatal shooting, disappearance from the jurisdiction, identity concealment, and later escape behavior. The source supports the chronology of these reported events more strongly than its psychological interpretation of them.

Observed Patterns and Case-Specific Context

Each entry separates the reported behavior or state from the analytical strength of the available narration.

Behavior / construct	Person / subject	Detailed case context	Evidence
Infidelity or competing attachment Relationship stressor	Colin Strickland Former PartnerLover of victim	The source places Strickland in overlapping relational commitments rather than a cleanly ended relationship. His continued contact with Wilson created a competing attachment within the resumed relationship with Armstrong. This structure is relevant to the reported jealousy and conflict but does not itself establish a motive for violence. Context or trigger: Strickland and Armstrong reportedly separated before Wilson visited Austin. Reported expression: Strickland described a month-long romantic affair with Wilson during the separation and continued contact with Wilson after resuming his relationship with Armstrong.	Explicitly reported Confidence: High
Separation or abandonment threat Loss or threat	Kaitlin Armstrong OffenderWife of the victim	The relationship appears to have remained unstable after the reported separation. Armstrong's belongings reportedly remained at Strickland's home while both partners pursued or considered other relationships. This ambiguity may have sustained perceived threat or insecurity, although the source does not provide a direct statement of Armstrong's internal experience. Context or trigger: Armstrong and Strickland reportedly separated, lived in a complicated household arrangement, and later resumed their relationship. Reported expression: The source describes a recent breakup, continued cohabitation or shared belongings, separate bedrooms, and conflict when Strickland communicated with Wilson.	Narrative-supported psychological state Confidence: Moderate
Jealousy Emotional state	Kaitlin Armstrong OffenderWife of the victim	The reported jealousy centered on Wilson as a specific perceived rival within Strickland's relationship network. The changed phone contact and arguments indicate that the issue was not merely a one-time disagreement. The source's stronger claims about fixation remain interpretive and should not be treated as a clinical conclusion. Context or trigger: Strickland reportedly remained close to Wilson after resuming his relationship with Armstrong. Reported expression: Strickland said communication with Wilson caused fights, and the source repeatedly frames Armstrong as unhappy about Wilson's presence.	Narrative-supported psychological state Confidence: Moderate
Deception or concealment Behavioral pattern	Colin Strickland Former PartnerLover of victim	The changed contact name represents concealment of a relationship communication. Strickland acknowledged the behavior during police questioning rather than presenting it as unknown. This concealment likely complicated the relationship system and later became relevant to investigators reconstructing the triangle. Context or trigger: Strickland was communicating with Wilson while Armstrong reportedly objected to the relationship. Reported expression: He changed Wilson's name in his phone because Armstrong had looked at his phone and the contact could start arguments.	Explicitly reported Confidence: High
Possessiveness or monitoring Control dynamics	Kaitlin Armstrong OffenderWife of the victim	The phone-checking account suggests intrusive monitoring within the relationship, but the source does not establish its frequency or full context. The later route reconstruction is presented as stalking by the narrator, while the underlying surveillance and location data are described only in summary. These elements are therefore more strongly supported as investigative facts than as a confirmed psychological construct. Context or trigger: Strickland reportedly communicated with Wilson during and after the relationship separation. Reported expression: Strickland said Armstrong had looked at his phone, and the source reports that investigators believed Armstrong followed the route toward Wilson's residence.	Analytical inference Confidence: Low
Premeditation and planning Planning or impulsivity	Case-wide	The reported sequence contains multiple acts that investigators interpreted as preparation or concealment rather than a single spontaneous confrontation. The source does not provide enough detail to determine when any plan formed or who carried out each act. The conviction is reported, but the psychological meaning of the conduct remains an inference from the narrated evidence. Context or trigger: The source reports vehicle positioning, a route toward the residence, firearm evidence, and later travel under another person's passport. Reported expression: Investigators reportedly identified a vehicle approaching the residence, a fatal shooting, subsequent international travel, appearance changes, and use of a fraudulent passport.	Analytical inference Confidence: Moderate
Detection avoidance or evasion Post-offense behavior	Kaitlin Armstrong OffenderWife of the victim	The reported post-incident conduct involved avoiding identification, leaving the jurisdiction, and attempting to evade custody. These acts are behaviorally relevant to detection avoidance and were treated by investigators as significant. They do not, by themselves, establish what psychological state preceded the homicide. Context or trigger: After investigators focused on her, Armstrong was reportedly absent and later found to have left the country. Reported expression: The source reports travel under her sister's passport, a one-way ticket to Costa Rica, altered appearance, and a later escape attempt during a medical appointment.	Explicitly reported Confidence: High
Emotional escalation Escalation	Case-wide	The case shows an escalation from relational instability to investigative indicators of physical danger. The source links the stages through jealousy and competing attachment, but it does not document every intermediate interaction. The escalation pathway is therefore supported chronologically but only partly supported as a psychological explanation. Context or trigger: The reported relationship triangle persisted through separation, reunion, continued contact, and jealousy. Reported expression: The narrative progresses from arguments and concealed communication to alleged monitoring, a shooting, flight, and continued evasion.	Analytical inference Confidence: Moderate
Impression management Post-offense behavior	Kaitlin Armstrong OffenderWife of the victim	The reported conduct appears directed at changing how Armstrong would be recognized by authorities and others. It is consistent with an attempt to manage identification and public presentation after the incident. The source does not establish Armstrong's subjective reasoning beyond the reported investigative interpretation. Context or trigger: Investigators reportedly searched for Armstrong after the homicide. Reported expression: The source reports appearance-altering surgery, use of a relative's passport, and work under a yoga-instructor identity while abroad.	Narrative-supported psychological state Confidence: Moderate

Source Limits and Cautions

The supplied material is a narrated video report with inconsistent names, compressed chronology, and commentary that sometimes treats inference as fact. No professional psychological assessment or diagnosis is reported. Some descriptions of obsession, stalking, body language, and motive are source commentary rather than independently documented clinical findings.
