The official said the woman, a New Zealand national, arrived in South Korea in 2018 and there was no record of her leaving the country. According to the official, the woman held Korean citizenship before acquiring New Zealand citizenship “a long time ago”. The official did not name the woman or provide other identifying information and could not confirm whether she was born in South Korea. His whereabouts are unknown, the official said. South Korean police have not launched their own investigation into the case, but are working with New Zealand authorities through Interpol. New Zealand police launched a homicide investigation earlier this month after a South Auckland family reported finding human body parts in several items they bought at an online auction from a storage facility. The children — believed to be between 5 and 10 years old — may have been dead for several years, perhaps three or four, according to New Zealand police. The family who bought the suitcases at auction are not under investigation, New Zealand police said. New Zealand police told CNN on Monday that they were unable to confirm the details provided by South Korean police at this stage of the investigation.
