Justin Weller

Fire & Explosion Scene Investigator, LaRovere Consulting

Fire & Explosion Investigation

Fire service and law enforcement experience, on one investigator

Justin Weller brings 13+ years in Arizona law enforcement and eight years in the fire service to LaRovere's fire and explosion investigations, backed by more than 1,200 documented hours of fire, explosives, and related technical training. He served as a firefighter, EMT, and hazardous materials technician before moving to law enforcement, where his duties included criminal investigations and bomb investigation.

On a LaRovere engagement, Justin documents the scene, preserves and tracks evidence, and works the origin-and-cause questions alongside our licensed engineers, who analyze the HVAC, gas, plumbing, and electrical equipment involved. That pairing answers both where a fire started and why the equipment failed.
