A 274 page investigation on the incident that led to Fresno Fire Captain Pete Dern falling through the roof of a burning house — sustaining major burn injuries — was released today.

The “Multi-Agency Serious Accident Review Team S.A.R.T. Investigation Report” is the most thorough report to date regarding the incident. It looks at different facets of the incident, from Fresno Fire Departments policies prior to the accident to what the damage to Dern’s equipment occurred.

Dern spent months in Community Regional Medical Center after the incident, but has since returned home and continues to recover.
