Dossier concerning Zhuang Ayou (莊阿佑), a 58-year-old man from Hunan, whose death in Shanghai in February 1945 was investigated as suicide by jumping from a building. The police report records that the incident occurred on the evening of 24 February 1945 and identifies Zhuang as the deceased. Police officers investigated the scene and compiled a formal report on the non-natural death.

The dossier contains an extensive series of witness interrogations concerning Zhuang's movements, personal circumstances, behavior before his death, and the circumstances of the jump. Witnesses were repeatedly questioned about whether they had directly observed the incident, whether there had been disputes or other suspicious circumstances, and whether they knew why Zhuang had taken his own life. The testimony does not establish a single definitive motive with sufficient certainty. The file subsequently passed to the prosecutorial authorities for formal examination of the corpse. The medico-legal documentation identifies the deceased as 莊阿佑, aged 58, native of Hunan, and records injuries associated with the fall. The final forensic conclusion attributes death to injuries sustained in the fall (跌傷身死).
