A six-year-old boy, his mother and the man they were visiting have died in a fire at a southern Queensland business.
Police said the three were at a residence in a large shed housing a trailer manufacturing business in the Toowoomba suburb of Torrington when the blaze broke out around 2.20am today.
Emergency services raced to the scene to find the shed well alight and the bodies of a 29-year-old woman and a 34-year-old man inside.
Early this afternoon, investigators discovered the remains of a boy, believed to be the woman's six-year-old son.
Further tests would be carried out to confirm his identity, police said.
It was not yet known how the fire started.
The man lived in the Carrington Road business and the woman and child had been visiting him.
Their deaths and another fire today prompted renewed calls for vigilance from acting Queensland Emergency Services Minister Judy Spence.
Fire crews were called to a home at Walloon, west of Ipswich, around 3am to find the two-storey house well ablaze.
The family, who had been asleep when the blaze broke out, escaped unharmed.
Ms Spence said there had been fewer house fires so far this winter and this may have lulled people into a false sense of security.
"We may have seen fewer house fires this winter than we have in the past few years but the fact of the matter is that the majority of house fires occur during the colder months and people cannot become complacent," Ms Spence said.
"Make sure your smoke alarms are working ... they can provide that vital early warning system."
Ms Spence said that in Queensland, 78 per cent of all home fire deaths happened in houses without smoke alarms.
