Common questions
Why does this division need peace-officer powers rather than acting purely as fire technicians?+
Wildfire causes can involve criminal conduct, such as arson or reckless equipment use, so investigators with peace-officer authority can execute search warrants, make arrests, and gather evidence in a manner that will hold up in criminal prosecution, not just produce a technical cause report.
What kinds of evidence does this division typically collect at a wildfire origin scene?+
Investigators document burn pattern indicators pointing to the origin area, collect physical evidence such as ignition devices or failed equipment components, and interview witnesses, combining fire dynamics analysis with standard criminal investigative techniques.
