Dossier concerning Pan Caishi (潘蔡氏), a 32-year-old woman from Wuxi (無錫), whose death in Shanghai on 5 June 1945 was investigated as suicide by ingestion of opium. The police non-natural death report identifies her by name, sex and age and initiates an investigation into the circumstances of the poisoning. The dossier contains an extensive police narrative and numerous witness interrogations concerning her family situation, activities immediately preceding the poisoning, and the circumstances in which she was discovered and taken for medical assistance.

The medical documentation from 惠旅養病院 identifies Pan Caishi as female, aged 32 and native of Wuxi, and records her address as No. 24, Lane 60, Yongshou Street (永壽街60弄24號). The hospital death certificate gives the time of death as approximately 8:40 a.m. on 5 June 1945 and states the cause as 鴉片中毒，急救無效—opium poisoning, with emergency treatment unsuccessful. The accompanying hospital record similarly documents the emergency condition in which she was received.

The case subsequently passed to the Shanghai prosecutorial authorities for formal judicial examination. The medico-legal examination again identifies the deceased as 潘蔡氏, aged 32, and records the physical condition of the body. The final forensic conclusion gives the cause of death as 服毒身死—death resulting from ingestion of poison.
