Methodology & Approach

Mr. Nagele's forensic approach is grounded in the IAPSC Forensic Methodology (Rev. January 2025) — a consensus-based, peer-reviewed framework reviewed and accepted by multiple Federal District Courts throughout the United States. Every engagement follows five structured phases: Phase 1 — Evidence Review and Synchronization: Systematic analysis of all discovery materials, incident reports, CCTV footage, post orders, crime history data, policies and procedures, security staffing plans, and site-specific documentation to identify factors contributing to the crime risks present at the time of the incident. Phase 2 — Security Risk Assessment: A qualitative, quantitative, or hybrid assessment identifying relevant risks based on the facts of the case to determine the likelihood that a vulnerability could be successfully exploited or a security countermeasure compromised. Phase 3 — Threat Assessment: Evaluation of actual and inherent threats, including site and vicinity crime history, calls for service, offense reports, and the relationship between the property's characteristics and the criminal event. Historical information including past criminal events forms the foundation of this analysis. Phase 4 — Vulnerability Assessment and Security Survey: Physical site inspection and analysis of security weaknesses, including building design, lighting, lines of sight, security equipment, guard force performance, post orders, and security management programs. Phase 5 — Analysis and Opinions: Determination of the adequacy of security at the location on the date and time of the incident, culminating in a comprehensive, evidence-based written report and professional opinions to a reasonable degree of professional security certainty. All forensic opinions are grounded solely in the evidence and the established Standard of Care. Mr. Nagele's commitment to impartiality ensures that testimony remains credible, unbiased, and defensible under the most rigorous cross-examination.
