A body has been discovered in the debris of a house that burned down in Blaxland earlier today (Friday).
Fire and Rescue NSW Blue Mountains Zone commander, Acting Superintendent Josh Turner, said crews from three stations responded to the fire at the Browns Road duplex about 1.20am today.
"Six fire trucks and approximately 20 firefighters were called to the job," he told the Gazette.
While the fire had engulfed the building, it was quickly extinguished and firefighters were able to prevent it from spreading into nearby structures.
"A body was discovered shortly after the initial extinguishment within the debris," Acting Superintendent Turner said.
"At one point in time search and rescue were searching for two people who were unaccounted for, however one-and-a-half hours after the call to the job and the discovery of one deceased person the second person was located at an alternate address."
Fire investigators, local crews and police forensic services were still on the scene this morning carrying out investigations into the fire, Acting Superintendent Turner said.
"The roof and structure of the complex is totally destroyed by fire," he said.
"It will be a tough one to determine the cause of because of the intense damage to the building."
A police statement said a crime scene had been established and a report would be prepared for the coroner in relation to the fire.
