A mother-of-five who escaped a fatal house fire which killed her young son has been put under police guard as she fights for life in hospital in a critical condition.
The home of Ellouisa Brighton Gibson, 36, and partner Justin Gibson, 34, in Harristown, 130km west of Brisbane, erupted up in flames just after midnight on Wednesday.
Five of the couple’s children – aged 4, 7, 11 and 18 – managed to escape with varying injuries.
But a body believed to be of her nine-year-boy was discovered inside during a search of the fire-ravaged property after firefighters managed to quell the blaze.
A formal identification is yet to be completed but Queensland detectives are now probing any history of domestic violence among the residents.
Ms Gibson was airlifted to Royal Brisbane Women’s Hospital with serious injuries, while Mr Gibson, 34, was taken to Toowoomba Base Hospital in a stable condition.
A four-year-old girl and seven-year-old girl were airlifted to Queensland Children’s Hospital where they remain in a critical condition.
Her 18-year-old son, Drake, was taken to Toowoomba Base Hospital where he has been treated for non-life threatening injuries. Her 11-year-old son escaped uninjured.

The family’s dog survived the fire and was being cared for by a neighbour.
Mr Goodman said firefighters were greeted with a ‘wall of flame and heavy smoke’ when they arrived at the scene as the fire mostly impacted the front of the home.
‘The guys had quite a difficult time making access and getting in to conduct a primary search,’ Mr Goodman said.
After speaking with a family member who was ‘hysterical’, Mr Goodman advised fire and rescue crews on where they might be able to find the missing child.
‘We’re all fathers, we’ve all got children, so its always hard, it’s a little bit harder when its sort of similar to your own situation,’ Mr Goodman said.
It took about 30 minutes for four fire crews to extinguish the fire.
