NRS-21060 | Crime Data Centre (formerly Modus Operandi): Murder files

The Modus Operandi Section of the Police Department was established in the 1930's. It was a section of the Criminal Investigation Branch until 1972 when it became part of the Technical Support Branch. The section's work is based upon the creation and maintenance of records relating to the methods used by persons in the performance of crimes and distinguishing characteristics of criminals in order to assist in the identification of criminals.The murder files contain Modus Operandi forms from 1961 when the murder files were separated from the Murder/Manslaughter files. They contain the record of interview.

警察局作案手法（Modus Operandi）科始建于20世纪30年代。该科室曾隶属于刑事调查科，直至1972年并入技术支援科。其核心工作为创建并维护两类档案记录：一是罪犯实施犯罪时所采用的作案手法记录，二是罪犯的独特身份特征记录，旨在辅助警方开展罪犯身份识别工作。该谋杀档案收纳了自1961年起的作案手法表格——1961年正是谋杀档案从原谋杀与过失杀人档案中独立拆分的年份；此类档案同时包含相关讯问笔录。
