The New York City Office of Chief Medical Examiner (NYC OCME) investigates approximately 9 000–10 000 deaths every year, each of which necessitates a formal identification. Although standard identification protocols resolve the majority of these cases, there are still a substantial number of long-term unidentified persons cases that require a targeted investigation. This process involves not only the comprehensive review of all available postmortem data (e.g. scene findings, personal effects, autopsy findings, toxicology results, forensic anthropology reports, dental findings, fingerprints, forensic biology), but also the collection of antemortem data through focused informant interviews, analyzing casefiles and/or archival records, reviewing public missing person postings (e.g. National Missing and Unidentified Persons System (NamUs)), and collaborating with law enforcement and other agencies. This holistic approach to identification investigations is systematic yet flexible, allowing for the needs of each unidentified person and/or missing person case to be thoroughly assessed and efficiently addressed. These efforts have proven successful at NYC OCME, resulting in over 80 long-term unidentified persons identifications confirmed in the last 7 years, dating as far back as 1969. This paper provides a detailed breakdown of the NYC OCME framework for long-term unidentified persons investigations, citing multiple case studies to underscore how investigators utilize multiple lines of evidence to generate potential leads. Although each jurisdiction faces a unique set of demands and limitations, sharing these investigative strategies and perspectives may benefit practitioners contending with long-term unidentified persons cases and their inherent complexities. Key points The NYC OCME oversees a large caseload of unidentified persons yet achieves a high rate of case resolution by applying a systematic and holistic investigation that involves a comprehensive review of postmortem data and the collection of antemortem data specific to a forensic identification. Analyzing multiple lines of postmortem biological and contextual evidence allows practitioners to hypothesize possible socioeconomic, cultural, and religious social identities that can be used to generate identification leads and inform comparisons to missing persons. Gathering as much detailed, accurate, and comprehensive antemortem data for a missing person is equally important when performing an identification comparison to a long-term unidentified persons (UP) and can better inform archival morgue records searches.
