Chief Fire Officer Bill Roo confirmed engaging officers only yesterday to start the probe.
“The buildings were all burnt down, which means all evidence have been destroyed. But we have established where the fire started,” said Roo.
“It started in one house and then spread to the others. So what we rely on now is the information from occupants of the house where the fire started and then we’ll work around what we gather.”
To identify the cause of fire, the victims of the fire and witnesses have to be interviewed and a timeline of events established.
