S.3 Ep.10- Minimize Cognitive Bias in Fire Investigation with Fire Investigator Nicole Brewer

Send us Fan Mail [https://www.buzzsprout.com/2327675/fan_mail/new] LIVE at the International Association of Arson Investigators ITC 2026, hosts Scott Kuhlman and Chasity Owens sit down with fire investigator Nicole Brewer for one of the podcast’s most insightful conversations yet. Nicole shares her journey from firefighter to fire investigator, her transition from public to private sector investigations, and how advanced education through Eastern Kentucky University and Oklahoma State University shaped her approach to forensic fire analysis. The discussion dives deep into scientific methodology, courtroom testimony, cognitive bias in fire investigations, and practical strategies investigators can use to strengthen their origin and cause determinations. The episode also explores the growing role of cognitive bias awareness in forensic science and how fire investigators can minimize unconscious influence during investigations. Nicole introduces her “Bias Minimization Worksheet” and explains how techniques like linear sequential unmasking and structured hypothesis testing can improve investigative reliability, courtroom confidence, and case defensibility. From real trial experiences and grand jury testimony to SAW (Scientific Advisory Workgroup) case reviews, this episode delivers valuable insight for both new and seasoned investigators looking to sharpen their methodology and elevate their professionalism in the field.

S.3 Ep.9- Live from IAAI-ITC with Dr. Greg Gorbett talking Fire Dynamics, Proficiency Testing, and the Future of Fire Investigation

Send us Fan Mail [https://www.buzzsprout.com/2327675/fan_mail/new] Live from IAAI ITC 2026 in St. Louis, Scott Kuhlman and Chasity Owens sit down with Dr. Greg Gorbett to talk fire investigation, research-based tools, and the future of the profession. The conversation covers the U.S. NRC Fire Dynamics Tools spreadsheets, heat release rate calculations, flashover correlations, and how investigators can use empirical data in defensible origin and cause work. Greg also discusses his recent election to the IAAI Board of Directors, the need for advanced training, competency testing, proficiency exams, NFPA 1321, and the growing importance of standardized processes in fire investigation. The episode also explores digital image analysis, line of demarcation interpretation, uncertainty in conclusions, courtroom confidence, and why “forensic honesty” matters when presenting fire investigation findings.

S.3 Ep.8- "Well Excluuude Me!"- Learning from Real Court Case Scenarios

Send us Fan Mail [https://www.buzzsprout.com/2327675/fan_mail/new] In this episode, hosts Scott Kuhlman and Chasity Owens break down real-world court cases where fire investigators were challenged, excluded, or dismantled under legal scrutiny. From Daubert challenges and summary judgment to spoliation of evidence and product liability battles involving companies like Amazon, this episode dives deep into what can make—or break—an expert witness in court. Learn how improper methodology, lack of qualifications, confirmation bias, and failure to follow NFPA 921 can cost a case, and how to protect yourself by conducting every scene as if you’re headed straight to trial. Whether you’re a seasoned investigator or just entering the field, this episode delivers critical insights to strengthen your reports, testimony, and credibility in the courtroom.

S.3 Ep.7- NFPA 921 Ch.6 Summary Part 2- Fire Patterns; Patterns, Plumes, and Proof

Send us Fan Mail [https://www.buzzsprout.com/2327675/fan_mail/new] In this episode, hosts Scott Kuhlman and Chasity Owens continue their deep dive into NFPA 921 Chapter 6 with Part 2: Fire Patterns. The episode blends real-world case studies with foundational fire science, reinforcing how fire investigators interpret patterns, validate origin hypotheses, and apply the scientific method in the field. Listeners are first brought into two compelling case studies: a hybrid vehicle fire with origin traced to the rear hatchback area despite severe damage, and a commercial fire involving a lithium-ion battery-powered blower where pattern interpretation was later confirmed through video evidence. These examples highlight the importance of pattern recognition, corroboration, and resisting premature conclusions. The discussion then transitions into core concepts from NFPA 921 Chapter 6, including fire effects, fire pattern generation, and pattern geometry. The hosts emphasize that fire patterns are not standalone proof of origin but must be analyzed alongside fire dynamics, heat release rate, ventilation, and witness statements. Key learning points include: *  Fire patterns reveal movement and intensity, not cause by themselves  *  Misinterpretation risks (e.g., “pour patterns”) and the importance of avoiding bias  *  The role of heat release rate and ventilation as primary drivers of pattern development  *  Practical application of the scientific method for origin determination The episode also explores legal-style questioning, helping investigators strengthen courtroom articulation and defend their methodology under scrutiny. To wrap up, the hosts introduce upcoming training opportunities and reinforce the importance of continued education, collaboration, and critical thinking in the evolving field of fire investigation.

S.3 Ep.6- NFPA 921 Chapter 6 Summary Part 1, Fire Effects; Can You Defend Your Fire Scene Analysis in Deposition?

Send us Fan Mail [https://www.buzzsprout.com/2327675/fan_mail/new] In this episode, Scott Kuhlman and Chasity Owens kick off their discussion of NFPA 921 Chapter 6 by breaking down one of the most important foundations in fire investigation: fire effects, and then fire pattens next episode. Using real-world deposition questions and courtroom-style challenges, they show why investigators must be able to clearly explain concepts like fire plume development, truncated cone patterns, U patterns, clean burn, oxidation, calcination, spalling, and more. The episode blends technical training with practical field insight, including stories from recent burn cell exercises, lessons from student investigations, and a blunt reminder that experience alone does not replace a solid grasp of the science. Scott and Chasity walk through key fire effects identified in NFPA 921, explain why these concepts matter in scene analysis and legal testimony, and highlight how misunderstanding or overstating pattern interpretation can seriously damage an investigator’s credibility. They also touch on upcoming training opportunities, fire death investigation work, industry events, hot surface ignition versus autoignition temperature, and the importance of continual study in a field where the basics can make or break a case.
