Peter Matthews talks with Bill Niemann, who spent nearly two decades in the Prince William County, VA, Fire Department Fire Marshal’s Bureau. During that time, Niemann and his team relaunched the department’s arson investigation unit and logged many headline-making arson arrests. 

Niemann provides insight into his 17-year assignment in the fire marshal’s bureau and the relaunch of their fire investigation unit, which they mostly built from scratch because there were no investigation standards or policies at the time. From attending the police academy to creating their own processes, Niemann and his small crew handled hundreds of arson fires annually.  

He reflects on some close calls and big blazes during his time as a line firefighter and some of the most memorable and impactful fire investigations and making high-profile arrests and how a serial arson case led him to the end of his career.
