Efficiency of Cooperation Between Various Services and Specialists in the Investigation of Terrorist Murders: Development of an Optimized Algorithm

BACKGROUND The study’s relevance stems from rising terrorist attacks and the need to enhance interagency efficiency in investigating terrorist homicides. The aim of the study is to analyse and improve mechanisms for interagency cooperation in the investigation of terrorist murders. MATERIALS AND METHODS The following methods were used in the study: relevance analysis, algorithm generalization, algorithm optimization, step-by-step structural qualitative comparative analysis, step-by-step structural element comparative analysis, and efficiency determination. RESULTS Among 25 analysed countries and organizations, only 32% demonstrated highly effective integrated cooperation models. The optimized algorithm reduced operational complexity by 20% (212 → 170 units), improving response speed, accuracy, and legal adaptability. CONCLUSION The academic novelty lies in typologizing interagency mechanisms and developing an optimized cooperation algorithm based on international practices. Further research should focus on pilot testing and scaling the model at national and international levels.
