The BEHAVE Investigative Framework by Alan Elangovan helps investigators connect behaviour, evidence, motive, timeline, vulnerability, risk, and findings. It supports fair, structured, evidence-based investigations by reducing bias, improving risk assessment, strengthening report writing, and helping investigators reach clear, defensible conclusions across criminal, workplace, school, healthcare, and security cases.
The Rapport-Based Interviewing Model, influenced by Clifford Stott, emphasises building trust, empathy, and communication to encourage cooperation. It supports investigators in reducing resistance, improving information quality, and fostering voluntary disclosure, making it highly effective in interviews, interrogations, and sensitive investigative contexts.
The Advanced PEACE Interviewing Model, evolved from UK Police practice, enhances the structured approach of Preparation and Planning, Engage and Explain, Account, Closure, and Evaluation. It emphasises ethical interviewing, rapport building, and information accuracy, supporting reliable evidence gathering and professional investigative interviewing standards.
The Questioning Funnel Model, influenced by the Socratic Method, guides investigators from broad, exploratory questions to precise, focused inquiries. It enhances critical thinking, uncovers deeper insights, clarifies inconsistencies, and supports effective information gathering, making it valuable in interviews, interrogations, and analytical investigative processes.
The Interview Funnel Model, influenced by John E. Reid, structures questioning from broad, open-ended inquiries to focused, specific questions. It helps investigators gather accurate information, clarify details, and assess credibility, supporting effective interviews, statement analysis, and progressive disclosure techniques in both cooperative and resistant subject interactions.
This article explains the PEACE Model as a structured and ethical investigative interviewing framework. It covers the model’s background, five stages, practical application, strengths, limitations, and relevance in modern criminal, workplace, compliance, and internal investigations.
