Fire Investigation

Integral to Prevention and Suppression of Fires

Fire/Arson Investigation is an integral component of community risk reduction, along with prevention and suppression of fires. Beyond its tremendous value of investigating fires, which is detailed below, this unit increases the efficiency of the fire department by reducing the frequency of intentional false calls to the department. Reducing false alarms allows the fire crews to stay available for genuine fire, medical, and other emergency response. The Unit also pursues potentially fraudulent private sector fire inspections.


The Fire/Arson Investigation Unit is responsible for investigating and determining the cause and origin of suspicious fires involving death or injury, and fires of undetermined origin.

Other duties include:
  • Arresting suspects and filing criminal charges as required with District Attorney's office.
  • Collecting and maintaining all evidence.
  • Conducting and documenting interviews with witnesses and/or suspects.
  • Performing and assisting with environmental crime investigations as needed.
  • Responsible for supervising the Juvenile Fire-setting Intervention Program.
  • Writing/filing investigation reports.
