 However, some reporters and non-governmental organizations (NGOs) questioned this explanation and suggested that she instead might be an unrelated woman who had been held in captivity.The woman stayed with the family until 2016, when a Vietnamese man claimed that the woman was his daughter who had disappeared in 2006 at age 23, following a mental breakdown.He was able to provide documentation about the woman's birth and disappearance, and shortly after brought her back to his village in Vietnam.
