This paper is based on oral investigation of the bereaved family of Yonaguni Island excluded from the public settlement process of the Taiwan 2･28. During the post-processing of the people whose survival status were not clear (the missing persons), a mixture of records from the bereaved families were found that indicated ‘death’ or ‘missing.’ As a result, the problem of ‘what is true’ is triggered in the process of requesting public approval of human casualties today. In the process of proceeding to allow those missing to be recognized as a “death” in the Taiwan February 28th cases, the Taiwanese government dismissed the application of the bereaved family by judging only the death certificate (the body examination document), death report, and the copy of the resident document as “exemplification.” The situation—in which the mysterious ‘missing’ that the upper generation recorded was judged to be ‘death’ in the public domain—served as a decisive opportunity for the bereaved families to re-recognize the connection between family history and the 2･28. In the past few years as applicants, they have reviewed the background and method of producing and operating each written record in the process of memory/rite of abnormal death by tracing how the disappearance of family members has been remembered and recorded. They were only told of the missing story from family members and only have the vague remembrance of childhood, but in this process they were able to learn the methodology to understand the contradictory records left by the upper generation. This has led to a new understanding that conflicting text records were the products of the upper generation’s desperate measure, and it was possible to reflect on the logic and wisdom that the bereaved family members displayed instantly in each phase of post-processing.
