Prosecutors decline detention for 60-year-old stalking suspect with stage 4 lung cancer

A 60-year-old man was arrested for murder in Seoul’s Eunpyeong District on the 5th, just two weeks after his electronic tracking device was removed. The suspect, identified by police as Mr. A, is accused of killing a 70-year-old woman, Ms. N, with whom he had a prior romantic relationship. Police found the victim dead at the suspect’s residence after receiving a missing person report at 6:40 a.m. that same day.

History of police reports and failed detention

Mr. A’s history of violence against the victim was documented in multiple police reports starting in 2024. Despite being reported to police twice—once in September 2024 and again in June 2026—the incidents were initially treated as minor disputes. By June 2026, authorities issued a temporary restraining order against Mr. A.

The situation escalated on July 18, when Mr. A was arrested for violating that order and assaulting the victim. Although the Mapo Police Station requested an arrest warrant for charges including stalking and assault, the prosecution denied the request. Officials cited the suspect’s health—specifically that he was suffering from stage 4 lung cancer and had recently undergone surgery—and his denial of the allegations as reasons to keep him out of custody.

Did You Know? Following the denial of an arrest warrant in July, police held Mr. A at the Seoul Southern Detention Center for one month, from July 23 to August 22, under a temporary protective measure. He was released and required to wear an electronic monitoring device until late last month, at which point the measures were terminated.

Limitations of protective measures

The decision to end monitoring was based on the fact that the victim did not request an extension. Even though Mr. A was included in a nationwide police sweep of high-risk relationship-based offenders conducted between September 19 and 30, no further action was taken because the victim did not express a need for additional intervention.

Expert Insight: The reliance on a victim’s request to maintain safety measures creates a significant gap in protection. As noted by experts like Heo Min-sook of the National Assembly Research Service, evaluating a suspect’s threat level based on health conditions or permanent residency often ignores the specific dynamics of relationship-based violence.

Police plan investigation once Mr. a is medically cleared

Mr. A was found at the scene with serious injuries from an apparent self-harm attempt and is currently receiving medical treatment. Police plan to conduct a formal investigation into the circumstances of the killing once he is medically cleared.

Why the suspect remained free and monitoring ended

Why was the suspect not in custody despite previous violent incidents?

The prosecution declined to issue an arrest warrant in July because the suspect was suffering from stage 4 lung cancer and had recently undergone surgery. Officials also noted that the suspect strongly denied the charges at the time.

Why did the electronic monitoring and restraining orders end?

Police stated that the temporary measures were terminated because the victim did not request an extension. Although the suspect was identified as a high-risk individual during a recent police survey, no further restrictive actions were taken based on the victim’s input.

What is the current status of the suspect?

The suspect is currently in a hospital receiving treatment for self-inflicted injuries sustained at the time of the crime. Authorities intend to proceed with a full investigation into the murder once his condition stabilizes.
