A woman was killed Friday in a residential structure fire in Oakley.
Firefighters with the East Contra Costa Fire Protection District responded Friday at 5:41 p.m. to a structure fire at a residence on Norcross Lane.
Firefighters arrived at the scene to find thick smoke and heavy fire coming from a duplex, and additional units were called in due to a woman reportedly still being inside the building.
Due to the heavy fire conditions inside the structure, fire units were deployed in a defensive fire attack from the exterior of the building and extinguished the blaze.
Once the fire was extinguished, fire crews conducted a primary search of the unit and found a deceased woman inside.
Crews conducted a secondary search of the unit and then conducted mop up, salvage and overhaul operations.
There were no reported injuries to firefighters.
The cause of the fire is under investigation.
