Research has mainly focused on the development and validation of molecular marker panels and associated statistical models to predict phenotypes. However, little is known about the operational value of DNA phenotyping, as perceived by the targeted users (i.e. police officers involved in criminal investigations). We used a questionnaire to survey 163 officers across Québec (Canada), and who are involved in major crime investigations, to better understand their knowledge and opinion regarding DNA phenotyping. Their responses show that a majority (63 %) are not yet familiar with DNA phenotyping. However, most respondents (58 %) support its use, especially for crimes against the person, if proven reliable. This research emphasizes the relevance of surveying police officers during the development and implementation of such operational forensic tools, as their expectations were not entirely in line with the current and anticipated possibilities of phenotyping, particularly with regard to the most useful traits to target. Respondents consider most useful predictions on eye colour, ethnicity, age and height, whereas it is biogeographical origin that is currently predicted (even if not a phenotype), and the last two traits are difficult to accurately predict. The perspective of police officers gathered here also argues in favor of involving other actors of the justice system to better delineate the scope of FDP in criminal cases and to improve its integration throughout the judicial process.</div></div>","PeriodicalId":36925,"journal":{"name":"Forensic Science International: Synergy","volume":"10 ","pages":"Article 100586"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143936683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fundamentally, chaos theory connects various scientific disciplines by explaining how seemingly random behaviors that happen in non-linear or “chaotic” systems, no matter how minor, can lead to major consequences. While forensic anthropology is often considered an a-theoretical subfield of anthropology, the discipline has witnessed a proliferation of theoretical publications in recent years. It engages with a variety of theories, ranging from low-level theories of archaeological recovery to high-level theories such as human evolution and adaptation to understand human variability. However, in its primacy, forensic anthropologists struggled to understand the systems and agents involved in forensic contexts. The utilization of chaos theory and non-linear systems has the potential to transform the field, providing a new lens to better understand forensic contexts.

This transdisciplinary research approach in sensitive medicolegal environments requires, first, establishment of a robust ethical framework (implementation of permissions, contracts, and ethics) to maintain evidentiary integrity and protect those involved. It also needs to facilitate dissemination of the generated facial depictions to the public to enable investigative leads. Second, it requires the identification of useful and available scientific analyses and establishment of the multi-disciplinary team. These include a medicolegal death investigation and a forensic pathology postmortem record review inclusive of forensic contextual and case data information (such as unique identifiers and personal belongings), radiographic analyses, osteobiography anthropological assessment, conventional and specialized forensic genetic analyses, and possibly stable isotope analyses to provide a richer picture and understanding of the person. Third, these multifactorial data need to be integrated into a narrative, including facial reconstruction and depiction to elicit memory and identification via public appeals for information on unresolved cases. Should an investigative lead be followed, and a possible forensic identification established, conventional methods to confirm identity can be applied (e.g. DNA profiling).
