A five-year-old boy rescued from a property on the Gold Coast may have been left alone with the bodies of two people, believed to be his parents, for more than a day, but police do not think he witnessed their murder.

The boy was found inside the Upper Coomera home by a female relative, along with the bodies of the 39-year-old woman and 43-year-old man. He was believed to be physically unharmed.

They are confident the boy did not witness the deaths but he spent the following day in the home with his parents’ bodies.

The murdered woman’s ex-husband, Christopher Robert Carter, faced Southport Magistrates Court on Thursday after being charged with two counts of murder.

The 36-year-old made no comment during his brief appearance and was remanded in custody.

The matter has been adjourned until March 27.

Detective Superintendent Dave Hutchinson said the horrific event has left several families in a state of shock and grief.

Det Supt Hutchinson said the boy was in the care of relatives and holding up relatively well considering his ordeal.

Describing the events as “highly traumatic”, Regional crime co-ordinator Superintendent David Hutchinson said police were “satisfied” the murders occurred on Tuesday night.

Supt Hutchinson said the victims had “some injuries” but would not go into further detail.

“We haven’t identified the deceased at this point but the child does live in the house,” Superintendent Huthchinson said.

“You would understand that a five-year-old child being in the house under those circumstances would have to be very traumatic – hopefully his age will be in his favour.

“We have a lot of enquiries still to make, we have a lot of police who have been recruited to assist,” Mr Hutchinson said.

“The examination of the house will continue and they [the police] will probably retain possession of the house for up to a week.”

A crime scene has been established at the house and forensic police are investigating.

One neighbour told the media group they heard loud arguing coming from the house on Tuesday night, but it stopped when they went to investigate.
