Relationship Pattern
Domestic Violence
Pattern Analysis
The relationship was marked by frequent arguments, controlling and aggressive behavior by Jiang Choi, and sexual coercion. The murder was preceded by escalating violence and controlling acts, culminating in strangulation during a confrontation. Post-incident behavior included tampering with evidence and seeking sexual encounters elsewhere, indicating detachment and lack of remorse.
Investigative Notes
Police investigation included review of security footage, forensic examination revealing strangulation and missing underwear, and discovery of evidence such as tape and ropes in the suspect's car. The suspect was arrested 10 hours after the body was found. He initially denied involvement but later confessed in court. The case prompted changes in hiring regulations for military and Coast Guard personnel in South Korea.
Investigation Confusion
Initial denial by suspect and conflicting statements about intent. Uncertainty about the missing underwear and absence of semen on the body. The suspect's behavior post-incident raised questions about premeditation versus impulsive violence.
Case Reconstruction / Puzzle Pieces
Hana and Jiang Choi met in June 2023 and had a tense, argumentative relationship. On August 14, they argued while traveling, leading to Hana leaving the car. They reunited in Mokpo on August 15, continued arguing, and went to a restaurant. At 3:22 a.m., Hana entered the restroom, followed by Choi who assaulted and strangled her.

Police arrested him and uncovered his history of aggression and controlling behavior. He confessed and was sentenced to 25 years in prison.
Risk Assessment
