Serial Killer on the Loose in South Korea’s Jeju Island?
Jeju Island serial killer fears explode as fourth dead body discovered in three days amid dozens missing Yonhap News

Four bodies have surfaced on South Korea's holiday island of Jeju in just three days, and a police officer now stands accused of covering up the disappearances that preceded them. The discoveries have triggered public alarm and online speculation about a serial killer, even as investigators say no such link has been established.

At the centre of the scandal is a mid-ranking officer, identified only by his surname, Bu, who is accused of falsifying hundreds of missing-person records rather than investigating them.

Four Bodies Found in Rapid Succession Across Jeju

The most prominent case involves Jang Mi-ran, 37, who vanished in mid-May. Her body was recovered on Monday, 24 August 2026, in a highly decomposed state at a palm farm in Hallim-eup, roughly a kilometre from where she had last been staying.

Police confirmed her identity through autopsy, and DNA analysis is continuing. Investigators said her body showed no clear signs of external trauma, and its position initially led officers to suspect hanging, though the exact cause of death remains under investigation, according to the Korea JoongAng Daily.

These details, disclosed in the autopsy report, are central to understanding the gravity of the police's failure to investigate her disappearance.

A separate case, reported by the Korea JoongAng Daily, involves a man in his sixties whose body was found on Jeju on Saturday, 22 August, at an undisclosed location. Officer Bu is also accused of fraudulently closing that man's missing-person case by falsifying records claiming contact had been made with him.

Social media users have circulated maps tracking the string of Jeju disappearances over recent weeks, feeding speculation of a common perpetrator. Investigators have not connected the four deaths to one another, and no evidence has been presented publicly to confirm a serial killer is operating on the island.

Officer Bu Arrested Over Falsified Records

The Jeju District Court issued an arrest warrant for Bu on Tuesday, 25 August, a day after he was briefly released from an earlier detention. He faces charges of dereliction of duty, falsifying and using official electronic records, and obstruction of official duties by fraudulent means.

'There are grounds to believe the suspect may flee or destroy evidence,' a judge said during Tuesday's pretrial hearing, according to the Korea JoongAng Daily. Bu was taken into emergency custody on Saturday, 22 August, before petitioning the court and winning release on Monday, 24 August, only to be detained again the following day.

Prosecutors allege Bu closed Jang's case without confirming her safety after she was reported missing on 15 May, then deleted her information from the police's internal profiling system. Investigators allege Bu told her boyfriend he had personally contacted her and that she did not wish her location disclosed, a claim unsupported by any phone records.

Prosecutors allege Bu closed more than 200 cases at his own discretion over roughly seventeen months, according to reports from the Korea JoongAng Daily and WION. Authorities are now reviewing the full caseload for further irregularities.

Senior Officers Suspended as President Orders Reform

The National Police Agency placed four senior officers at Jeju Seobu Police Station on administrative leave, including the current and former station chiefs and two senior investigators, as scrutiny turns to how one officer was able to close so many cases without oversight.

President Lee Jae-myung has ordered a full investigation into how the cases were handled and called for broader reform of missing-person procedures nationally. 'With great investigative authority comes great accountability,' Lee said in remarks addressing the scandal, according to the Korea JoongAng Daily.

The National Police Agency has since begun reviewing missing-person procedures more widely, including proposals to require stronger supervisory sign-off before any case can be closed.

Colleagues of Bu told the Korea JoongAng Daily they could not explain his conduct, with the outlet reporting that fellow officers 'couldn't conjure up any semblance of justification' for the scale of the falsifications.

No Confirmed Link to a Single Killer, Police Say

Despite mounting public fear, investigators have stressed that claims of a serial killer, homicide, or trafficking network remain unverified.

More than a dozen people have gone missing on Jeju in recent weeks, but police have not established a common cause of death or a single suspect linking the cases.

The scandal has nonetheless exposed what government officials and police leadership have described as systemic failures in how Jeju police handled missing-person reports.

These failures are now the subject of both a criminal prosecution and a national policy review.

The case continues, with prosecutors expected to formally indict Bu in the coming weeks as the wider review of Jeju's police conduct unfolds.
