The 56-year-old’s body was found by paramedics on a bed at the Victoria Point home after being called there about 2am on Wednesday.

Detective Superintendent Andrew Massingham says the woman’s de facto husband, 58, let Queensland Ambulance Service officers into the home.

“He was emotional and upset. He allowed access into the residence from QAS,” he told reporters on Wednesday.

“I think at that time he was aware of the state of the deceased and was quite traumatised by that.”

The man voluntarily handed himself over to detectives, who have been questioning him about the circumstances of his partner’s death.

However, police haven’t found any weapons at the scene, and are still trying to work out if the woman’s death is suspicious, with “a large amount of blood” found in the home.

“Until the autopsy is undertaken and a number of investigations are finalised, we will not know if this death is suspicious at this time,” Massingham said.

An autopsy will be undertaken on Thursday. Police are also probing the couple’s relationship.

There are no current domestic violence orders involving the pair, but Massingham said the woman called police to the home about a month ago.

At the time, officers spoke with her partner at the home, he said.

Detectives are reviewing that incident and the conversation, and are also probing whether the woman had an illness in the lead-up to her death.

“There is a number of factors in relation to that, that we are looking at, at the moment,” Massingham added.

“As you can appreciate those inquiries do take some time to follow through particularly with family members and medical experts.”

Police have doorknocked the area, but no neighbours heard any disturbance on Tuesday night.
