Yili Murdered by Liu Xiuying, Jiangsu, China
This source-based behavioral analysis does not establish a clinical diagnosis, motive, or legal finding.
This case involves prolonged domestic abuse rooted in family opposition, traditional control dynamics, and escalating violence culminating in homicide. The victim endured emotional and physical abuse from her mother-in-law, with limited spousal support, leading to severe psychological and physical harm.
The relationship was marked by a power imbalance favoring the mother-in-law, who exerted coercive control and emotional abuse over the daughter-in-law. The husband sided with his mother, reinforcing the victim's isolation and vulnerability. Family pressure and conflicting social backgrounds contributed to ongoing conflict.
The pathway to homicide involved sustained verbal and emotional abuse, physical violence provoked by the mother-in-law, failed intervention by the husband, and eventual lethal attack by the mother-in-law while the husband was absent.
