Gender Identity in Forensic Death Investigation: A Narrative Review and Suggested Guidelines for Documenting and Reporting.

ABSTRACT: In the current body of forensic literature, there is little guidance available regarding death investigations of transgender, intersex, and gender diverse individuals. An increase in the prevalence of gender diverse identifying people and the frequency in which these individuals experience a premature death makes it more likely these deaths will fall under the jurisdiction of the medical examiner's office. The inability to navigate these diverse cases due to a lack of training, education, and support may leave forensic professionals without the tools needed to accurately represent these deaths.This narrative review is intended to provide the foundational knowledge needed by forensic death investigators when investigating gender identity in death, including suggested guidelines for a more effective and empathetic death investigation. A better understanding of the implications and applications of this information when included in reports will bolster the quality and quantity of the data reported and collected. This will lead to more accurate monitoring and reporting of violent, suicidal, and homicidal deaths of transgender, intersex, and other gender diverse individuals, and a higher identification rate of unidentified remains with gender diverse markers.

Identification of a decedent in a 103-year-old homicide case using forensic anthropology and genetic genealogy.

Anthropologists are often the custodians of long-term unidentified human remains though their positions as curators of university or museum skeletal collections. Various factors decrease the solvability of these legacy cases including the passage of time, the loss of provenience for specific cases, and lack of documentation or case records. While anthropologists can contribute important information toward identification, it is often necessary to explore novel and cross-disciplinary strategies to resolve difficult cold cases. In long cold cases, the postmortem interval, in particular, may be difficult to estimate leading to further challenges in achieving identification. Modern advances in radiocarbon bomb pulse dating, isotope analysis, and actualistic studies have contributed to positive identification of unidentified human remains in some legacy cases, but may not be available to all forensic practitioners and law enforcement from resource-poor agencies. Pooling resources, as well as collaborating with professionals outside of forensic anthropology, is a useful strategy to pursue when anthropological methods are exhausted.The case study presented here demonstrates a collaborative approach between forensic anthropologists, forensic genetic genealogists, and law enforcement in a century-old homicide. The dismembered and mummified parts of a male body were recovered in a remote cave in 1979 and again in 1991. Despite forensic anthropologists creating and updating the biological profile over the decades from recovery to present, no identification was made until the application of forensic genetic genealogy (FGG) to the case in 2019. New interpretations of bone microstructure and trauma analysis are presented for the case, alongside the historical documentation and "proof of life" evidence used by the genealogy team. A review of the FGG methods underscores the challenges in this case (e.g. significant endogamy, multiple aliases used by the victim) and the steps taken toward resolution. Ultimately, a combined anthropology and genealogy approach resulted in a confirmed identity for a man who was murdered in 1916.Key pointsForensic scientists should leverage a collaborative, interdisciplinary approach toward human identification.When combined with forensic anthropology methods, forensic genetic genealogy is a valuable tool linking biological and cultural-historical aspects of identity.Forensic anthropologists should review challenging cases in their labs as new methods are introduced and new resources become available.
