One dead in Sydney fire A PERSON has died in a house blaze in Sydney's north. The body of the missing person, originally reported as a child but now believed to be an adult, was found following the Mount Colah fire, a Fire and Rescue spokeswoman said on Wednesday afternoon. Police say a mother and son have been taken to Hornsby Hospital suffering from smoke inhalation. The fire has been extinguished and investigators are on the scene. Lancelot Street, where the fire broke out, has been closed. Inspector Kim Simpson, who ran the operation, said about 20 firefighters stopped the fire from spreading but couldn't save the one person inside. "The guys tried to get inside but were driven out by intense heat," Inspector Simpson told AAP. I can confirm that two people self evacuated. He said the deceased person's gender is still unconfirmed and their body remains in the house while investigations takes place. Inspector Simpson said he had no reason to believe the fire was suspicious. It is a tragedy, any loss of life is a tragedy. About 80 per cent of the house had been destroyed.
