The Sindang Station Stalking Murder

On September 14, 2022, a Seoul Metro employee was killed inside Sindang Station by former colleague Jeon Joo-hwan. By then, Jeon had already been prosecuted for stalking, threatening and illegally filming the same woman. The murder occurred one day before a court was due to sentence him in a stalking-related case.

Stalking before the murder

Jeon and the victim had worked for Seoul Metro. Prosecutors later described a prolonged pattern of stalking, threats and digital sexual abuse. The victim had reported him, and criminal proceedings were in progress before the killing.

This sequence is central to the case: the murder was not investigated as an isolated encounter. Prosecutors charged Jeon with retaliatory murder, arguing that the killing was connected to resentment over the victim's reports and the criminal case against him.

The killing at Sindang Station

The victim was working at Sindang Station on September 14, 2022 when Jeon attacked her in a women's restroom. Authorities did not publicly identify the victim by name, and this page follows that privacy practice.

Trial and sentencing

In February 2023, a Seoul court sentenced Jeon to 40 years in prison for the revenge murder. He had separately received a nine-year sentence on stalking, illegal-filming and threatening charges.

The cases were combined at the appellate stage. On July 11, 2023, the Seoul High Court imposed life imprisonment, ordered 15 years of electronic location monitoring after release if applicable, and required treatment programs addressing stalking and sexual violence.

Supreme Court decision

On October 12, 2023, South Korea's Supreme Court dismissed Jeon's appeal and finalized the life sentence. The court also left the electronic-monitoring and treatment orders in place.

The final judgment matters editorially because it removes any ambiguity about Jeon's criminal status. He is not merely a suspect or defendant; his life sentence is final.

Institutional aftermath

The murder led to scrutiny of stalking-law enforcement and workplace safety at Seoul Metro. Jeon had remained able to access internal systems while removed from active duties, and later civil litigation examined whether the operator had failed in its duty to protect the victim.

In July 2025, an appellate civil court ordered Seoul Metro to compensate the victim's parents, reversing an earlier first-instance loss. That civil ruling is separate from Jeon's criminal conviction and does not change the life sentence.
