Dossier concerning Li Zhangshi (李張氏), a 45-year-old woman from Shandong, whose death in Shanghai on 20 August 1944 was investigated as suicide involving a self-inflicted knife wound. The police death report identifies the deceased and records the circumstances of the death, while the subsequent investigation contains extensive statements from her husband, Li Hengchun (李恆春), and other persons acquainted with the family.

The witness testimony indicates that Li Zhangshi had suffered for approximately three years from a condition described in the documents as 神經病. Testimony concerning the couple's domestic relations states that she and her husband generally lived on good terms, suggesting that the investigation did not establish marital conflict as the principal explanation for the suicide. The police nevertheless questioned relatives and neighbors in detail concerning her health, behavior, family relations, and the circumstances immediately preceding her death.

The dossier also preserves physical evidence connected with the case. An official evidence inventory records a small knife (小刀乙把) and a blood-stained garment (血衣一件). The formal medico-legal examination identifies the deceased as 李張氏, aged 45 and native of Shandong, and documents a knife injury to the abdomen. The final forensic conclusion states 委係刀傷身死—that death resulted from a knife wound.
