A 28-year-old woman made an emergency call after being abducted in Suwon, but police failed to locate her in time. Oh Won-chun was convicted of kidnapping and murder; an appellate court replaced his first-instance death sentence with life imprisonment, and South Korea's Supreme Court finalized that sentence.

Late on April 1, 2012, a 28-year-old woman whose name was withheld by major South Korean news reports was abducted in Jidong, Suwon. She managed to call the 112 emergency line and gave police information about where she was being held. The response failed to reach her in time. Police found her dead the following day at the home of Oh Won-chun, also rendered in some English-language reporting by the Chinese reading Wu Yuanchun.
The victim contacted police shortly before 11 p.m. and reported that she had been abducted and was being attacked. She described the area as a house between a playground and an elementary school in Jidong. Authorities initially gave the public an inaccurate account of the length and usefulness of the call; later disclosures showed that it lasted several minutes and contained more location information than first acknowledged.
Police mobilized officers, but the search did not identify the correct residence before the victim was killed. Her body was found roughly thirteen hours after the emergency call. The failure became a national scandal because the emergency information had offered investigators a meaningful opportunity to narrow the search area.
Oh was arrested at his residence. Prosecutors charged him with kidnapping, murder and related offenses, including conduct connected to attempted sexual assault and damage to the victim's body after death.
During the case, speculation developed that the postmortem conduct might have been connected to trafficking in human tissue or other organized activity. That theory was never established as fact. It matters because the courts treated the absence of proof for such an additional motive differently at successive stages.
On June 15, 2012, the Suwon District Court sentenced Oh to death. The judgment also ordered ten years of public disclosure of his personal information and thirty years of electronic monitoring. The first-instance court considered the crime exceptionally serious and entertained a possible purpose beyond attempted sexual assault.
On October 18, 2012, the Seoul High Court reduced the death sentence to life imprisonment. Crucially, the appellate court did not accept that the prosecution had proved the more speculative theory about an additional trafficking-related purpose. The murder conviction itself remained intact.
This distinction prevents an unsupported allegation from being repeated as a settled motive. Oh was convicted of the kidnapping and murder; a sensational theory that circulated after the crime was not proved to the standard required by the appellate court.
On January 16, 2013, South Korea's Supreme Court rejected the prosecution's appeal seeking restoration of the death sentence and finalized life imprisonment. The final judgment also retained the ten-year disclosure order and thirty-year electronic-monitoring requirement.
The case is therefore classified Solved / Adjudicated. The offender's criminal responsibility is final even though aspects of motive discussed during the early proceedings were not proved.
The murder also became a case about emergency-response accountability. National Police Agency Commissioner General Cho Hyun-oh offered his resignation after criticism of the handling of the victim's call. Police publicly apologized, and South Korea accelerated changes intended to make it easier for officers to obtain the location of emergency callers.
A revision allowing police to request mobile-location information for 112 callers without prior permission was scheduled to take effect later in 2012. The reform was widely described as an effort to prevent a recurrence of the failures exposed by the Suwon case.
The final life sentence confirms Oh Won-chun's responsibility for the kidnapping and murder. This dossier does not present unproved claims about human-tissue trafficking or other organized criminal activity as fact; the appellate court specifically declined to accept the evidentiary basis for that theory.
