Case Overview

This source-grounded psychological and behavioral analysis examines the interpersonal dynamics and behavioral patterns surrounding the homicide of Preeti Yadav by Monu Singh in Noida, India. The narrative reveals a complex relationship marked by extradyadic attachment, escalating conflict, and violent aggression culminating in the fatal incident. The analysis focuses on the reported emotional states, relationship stressors, control dynamics, planning and impulsivity, and post-offense behaviors as described in the transcript, without clinical diagnosis or assumptions beyond the narrated evidence.

Relationship Dynamics

Preeti Yadav and Monu Singh engaged in an extramarital affair despite both being married to other partners. Preeti left her husband due to marital dissatisfaction and lived separately with her children while working in a factory. Monu and Preeti's relationship evolved from friendship to a romantic and sexual attachment, with Preeti frequently visiting Monu's home and pressuring him to divorce his wife and marry her. Monu resisted this demand, citing his marital status and financial limitations. Preeti's insistence on marriage or financial compensation, coupled with disparaging remarks about Monu's daughters, intensified conflict. This prolonged interpersonal conflict, combined with possessiveness and control attempts by both parties, escalated to physical violence. The relationship was characterized by emotional escalation, coercive control, and maladaptive coping, ultimately leading to the homicide.

Escalation Summary

The pathway began with the development of an extradyadic attachment between Preeti and Monu, followed by Preeti's increasing demands for marriage or financial support. Monu's refusal and Preeti's threats against his daughters triggered anger and resentment in Monu. On November 5, a confrontation during a meeting led to Monu's impulsive aggression, resulting in Preeti's death by repeated blows with a weapon. Post-offense, Monu engaged in staging and evidence concealment to prevent identification and detection. The pathway reflects a progression from relationship stressors and emotional escalation to lethal violence and deliberate post-offense actions.
