The Criminal Division 2 of the Seoul Southern District Public Prosecution Office, headed by Chief Prosecutor Jeong Hyeokjun, said on November 13 that it had indicted and detained a woman in her 40s surnamed Park on a charge of murdering her lineal ascendant.


Park was indicted on suspicion of killing her biological mother, who was in her late 60s, at their home in Ujangsan-dong, Gangseo-gu, Seoul, on October 22.


According to the prosecution office, Park had received treatment for a mental illness for about 14 years, beginning around 2012. Investigators concluded that she committed the crime after becoming delusional when her mother made seaweed soup for her birthday, believing that her mother was trying to feed her poisoned food.


Earlier, at around 8:15 a.m. on the day of the crime, Park called the police herself. At the time, she said, "I did something bad to my stepmother." However, a police investigation confirmed that the victim was her biological mother, and the charge was changed from murder to murder of a lineal ascendant.


Park's daughter also reportedly called the police on the day of the crime after hearing Park say during a phone call, "Grandmother tried to feed me food containing poison, so I scolded her." However, police found no poison at the scene.



A prosecution office official said, "We will make every effort to ensure the prosecution of the case," adding, "We will do our utmost to help the victim's bereaved family recover from the crime by providing support such as living expenses, psychological counseling, and housing costs."
