Case Summary
In 1999, Kim, a 41-year-old married insurance planner, was involved in a love triangle with two men: Jeong, a 40-year-old public official from Sacheon City Hall, and Kim, a 45-year-old construction worker. Jeong, enraged by the affair and its exposure, stalked and ultimately strangled the construction worker Kim to death near Gasan Bridge in Sacheon City. The body was tied with rope, placed in the trunk of the woman's car, and later disposed of in a well near Dotongsa Temple in Daepyeong-myeon, Jinju City. The woman witnessed the murder and was threatened by Jeong to remain silent. Despite initial distrust of the police and refusal to testify, the woman eventually cooperated after persistent persuasion. The police conducted a thorough investigation, including mobilizing local contractors and residents to locate the submerged well where the body was found after over two weeks of effort. Jeong was arrested after police rammed his car to force his appearance. He initially denied the crime but confessed after being confronted with evidence. The case was notable for its complex relationship dynamics, the challenges in investigation due to terrain changes and local distrust, and the eventual successful resolution. Jeong was sentenced to a long prison term, estimated between 20 to 30 years.

The public official, feeling betrayed and threatened by exposure, planned and executed the murder of the construction worker lover. The female witness was coerced into silence through threats and abuse, illustrating coercive control and domestic violence dynamics within the relationship.
Investigative Notes

Persistent police work, including mobilizing local contractors and residents, led to the discovery of the body. The suspect was arrested after police forced his appearance. The female witness's eventual cooperation was crucial. The case highlights issues of police bias and community distrust in 1999.
Investigation Confusion
Initial refusal of the female witness to testify due to distrust of police and fear of the suspect complicated the investigation. The absence of the body and changes in the landscape delayed evidence recovery. The suspect initially denied involvement despite evidence.
