Case Overview

This case involves a prolonged pattern of grooming, coercive control, and sexual abuse within a family relationship, highlighting the psychological dominance exerted by the offender over the victim despite her apparent independence.

Relationship Dynamics

The uncle established a dominant-subordinate relationship with his niece, controlling her behavior and outings, and using threats and intimidation to maintain power. The victim's social and economic independence was insufficient to overcome the psychological bondage created by grooming and coercive control.
