Examining the Roles of Police Investigators in Criminal Investigation of Missing Persons, Human Remains Identification, and Crime Documentation: Basis for Policy Recommendation

This study examines the demographic profile, existing operational guidelines, investigative roles, encountered challenges, and overall effectiveness of police investigators involved in cases related to missing persons, human remains identification, and crime documentation across five police districts. Utilizing a mixed-methods approach, quantitative data were gathered from 25 respondents spanning various ranks, units, and years of service, complemented by qualitative insights to provide a comprehensive understanding of operational realities. The findings indicate that while police investigators generally have access to clear and comprehensive guidelines, the implementation of these protocols is hindered by moderate challenges, including insufficient resources, limited forensic technology, difficulties with inter-agency coordination, and gaps in training. Investigators are actively engaged in critical functions, including interviews, site processing, forensic coordination, and crime scene documentation, with investigative skills playing a crucial role in the successful resolution of cases. Statistical analysis reveals a strong and significant positive relationship between adherence to standardized operational guidelines and the effectiveness of investigations. To address the identified gaps, respondents recommend enhancing and regularly updating guidelines, institutionalizing continuous scenario-based training, investing in forensic infrastructure, strengthening inter-agency collaboration, and promoting community awareness and engagement
