Dossier concerning the deaths of two Russian women, Raissa Zartsine (柴爾先何; stamped in the file as ZARTSINE RAISSA) and her mother Anna Lyssai (李薩雅; stamped LYSSAI ANNA), who were found dead in their residence at 156/23 Route A. Courbet, Shanghai, on 22 June 1945. Raissa Zartsine was 54 years old and is described in the English police documentation as a physician/doctor. Her elderly mother had no occupation. The English police report gives the mother's age as 85, while the later Chinese medico-legal form appears to record 80, creating a documentary discrepancy.

After the women had not been seen since the previous day, building personnel and another resident contacted the police. Officers entered the premises after finding the room locked from the inside. Anna Lyssai was found lying dead on a couch, while Raissa Zartsine was found hanging by a cord/string. The police observed that the room was arranged in orderly fashion, found no evidence of a struggle, and recovered the key inside the room. Both women were transported to the First Hospital of the Red Cross Society of China, 363 Avenue Haig, where they were recorded as brought in dead.

The investigation contains extensive English- and Chinese-language witness testimony concerning the women's circumstances before their deaths. Particularly significant is the statement of Elizabeth Tonoff, another resident of the premises. She testified that shortly before her death Zartsine had been corresponding with the Japanese-controlled management or owners of the property and had received a final communication stating that the flat would be regarded as vacant from 1 July 1945 and that no further correspondence would be answered. Tonoff recalled Zartsine discussing arrangements concerning herself and her mother in connection with this situation.

The dossier also includes detailed inventories of the women's belongings, arrangements concerning their property and estate, witness statements, hospital certificates, police reports, and formal medico-legal documentation. The subsequent forensic records confirm the identification of both women. The evidence clearly establishes hanging as the mechanism of Raissa Zartsine's death. Anna Lyssai was found without obvious external traumatic injury; the surviving documentation does not establish her precise physiological cause of death with the same clarity, although the archival heading and police investigation classify the incident as the joint suicide of mother and daughter.
