In this episode, Scott Kuhlman and Chasity Owens are joined by Fire Investigators Bill Strohm and Oliver Gillespie to explain how their fire investigation unit operates and why their structure leads to strong case outcomes. They break down the roles of shift investigators, who handle origin and cause, evidence collection, and witness interviews at active scenes, and day-shift investigators, who manage follow-ups, warrants, law enforcement coordination, and case preparation for prosecution. The team discusses how having two investigators on scene helps reduce bias and strengthen findings, the importance of building relationships with partner agencies, and how persistence and collaboration support long-term arson investigations. The episode closes with practical advice for solo investigators on capturing perishable information, staying disciplined with the scientific method, and communicating technical concepts clearly in court.
