A 26-year-old social service worker, Kim Seong-woo, has been charged with murdering his mother-in-law and kidnapping his wife, who was in the process of filing for annulment. According to Yonhap News, the Songpa Police Department transferred Kim to the Seoul Eastern District Prosecutors' Office on charges of retaliatory murder, retaliatory confinement, and violations of the Special Act on the Punishment of Specific Crimes, as well as the Act on the Punishment of Stalking.


On October 11, at approximately 5:35 a.m., Kim allegedly went to his mother-in-law's home in Songpa and fatally stabbed her with a weapon while attempting to forcibly take his wife, who was screaming for help. The mother-in-law was found at the scene in cardiac arrest and was transported to a hospital, where she was pronounced dead. His wife, identified as A, was threatened with a weapon and forced into a vehicle, then taken to a mountainous area in Yangyang County, Gangwon Province, where she was held captive.


Kim and A registered their marriage in February but began living apart in August. A filed for divorce mediation at the end of August but later withdrew the application and was pursuing an annulment lawsuit.


The police have been investigating the case as a planned crime, noting that Kim waited near the crime scene for about four hours while carrying a weapon. Meanwhile, the Seoul Metropolitan Police Agency held a meeting of the Personal Information Disclosure Review Committee the previous afternoon, during which they decided to release Kim's name, age, and mugshot.
