Psychological & Behavioral Intelligence

The source describes Kang as discovering that Dang was not a single mother but remained married to Tai Pong. Despite anger and disappointment, he reportedly stayed because he was deeply attached to her. This suggests a dependency pattern in which preserving access to the relationship took priority over an ordinary reciprocal partnership.

The report describes a concealed romantic relationship operating alongside Dang's marriage. Tai Pong reportedly believed Kang was a household helper and did not know about the affair. This concealment created a structurally unstable household in which several people occupied conflicting relationship roles.

Dang was described as maintaining a marriage while also having a secret relationship with Kang and allegedly other relationships. The report presents these overlapping attachments as central relationship stressors. The accounts are not independently verified and should be treated as allegations within the narrated case.

Kang reportedly objected to Dang having relationships beyond him and her husband. His attention became focused on alleged rivals and on demanding explanations about his place in Dang's life. The source frames jealousy as a major emotional stressor, while the prosecution disputed the defense's broader psychological interpretation.

The reported March 1989 separation effort threatened both Kang's romantic attachment and his living arrangement. His continued presence meant that the relationship conflict could not be ended through physical separation. The source later interprets the threatened loss of the household as more important than jealousy alone, but that interpretation remains source-limited.

The relationship was not described as a single isolated dispute. The report presents years of unresolved conflict involving secrecy, paternity, competing partners, and household roles. Neighbors allegedly noticed Kang's bad temper and recent arguments with family members, indicating that the conflict was visible outside the couple.

The reported focal incident followed a domestic argument that rapidly became physical. The source says Kang lost control after the confrontation and used objects and weapons against household members. The prosecution and forensic evidence disputed parts of his narrative, but the reported sequence shows a sharp escalation from verbal conflict to lethal violence.

Although the defense characterized the incident as an uncontrolled explosion, the source also reports sequential conduct involving multiple weapons, cleanup, temporary storage of bags, child collection, and travel to Macau. These behaviors may support an inference of organized post-incident conduct. They do not by themselves establish the mental state required for legal guilt.

The source describes cleanup and the temporary placement of bags outside the apartment. This conduct is consistent with possible evidence concealment or scene management, although the report does not establish exactly what the bags contained. The shopkeeper reportedly did not open them.

The report says Kang took Tai Wei Quin to Macau and left him with relatives before disappearing. His prolonged absence led police to issue a warrant and reward. This is behavioral evidence of evasion after the incident, not proof of a particular psychological motive.

Truong's reported suicide occurred approximately two years before the focal homicide and was presented as a consequence of distress about her daughter's conduct. The source gives no clinical records, method, or independent corroboration. It should therefore be treated as a reported historical event rather than a clinical formulation.
