Prime Minister Han Seong-sook on Monday vowed zero tolerance for mishandling missing person cases after a Jeju police officer was arrested for closing cases without confirming the missing people’s safety. She ordered the National Police Agency to examine all missing person cases nationwide and overhaul the system, including separating investigation from case closure. President Lee Jae Myung also called for scrutiny of the police investigation system. The case involved Jang Mi-ran, 37, whose body was found earlier Monday more than three months after she was reported missing.
