Police have bailed the partner of Veronica Wellings, after he was charged with breaching bail and a domestic violence order, following the death on Monday of the 40-year-old mother of three.

Joshua Denne, 39, was granted bail to appear in court in June after an autopsy on the woman failed to identify a clear cause of death.

Assistant Commissioner Domestic Violence and Youth, Michael White, said police would continue to work with the coroner to determine the cause of Ms Wellings’ death.

He said there was no requirement for Mr Denne to remain in custody, and no evidence he was involved in Ms Wellings’ death.

He acknowledged that bailing a man just charged with breaching bail and a domestic violence order could cause confusion with the public, but said any breaches would be subject to further charges.

Assistant Commissioner White said Mr Denne was subject to a current DVO in relation to three other people, associated curfew conditions and had been fitted with an electronic monitoring device.

“At this stage the indication is she died of a medical condition, but obviously we’re looking at what was the cause of that condition in the first place,” Assistant Commissioner White said.

“There’s a number of tests still underway as part of the autopsy process, and obviously as those tests come back we’ll be able to make further determination as to cause of death.”

Mr Denne was arrested on Monday after Ms Wellings died at Royal Darwin Hospital following her admission in a critical condition earlier that day.

Police said about 9am emergency services received reports of a “seriously ill” woman at a Humpty Doo residence.

On Monday evening police said investigations were open into the woman’s “suspicious death” that morning.

Assistant Commissioner White said Mr Denne had called the ambulance, that later delivered Ms Wellings to Royal Darwin Hospital, to his Humpty Doo residence .

“I can say (Denne) was the person who called the ambulance,” he said.

“They were at the same residence together, obviously in breach of his DVO.

“They had been separated and at some point, which will form part of the investigation, is how they’ve reconnected and been back in the same place.”

He said police were investigating a number of aspects in relation to Ms Wellings’ cause of death.

“A number of samples have been taken for various types of testing,” he said.

“In the circumstances we’re trying to determine what the cause of the illness was that she died of.

Veronica Wellings loved art and music.

“We’ve not excluded any offences in relation to this investigation.

“The next step is we’re continuing to interview witnesses. We’re seeking information from anyone in the public that may know them and have any information that they think may or may not be relevant.

“Any piece of information anyone has would be relevant to this matter and we ask that anyone comes forward.”

Police have declared this a major investigation, naming it Operation Cobark.

Assistant Commissioner White said bailing Mr Denne should not be a signal to women around the police force’s view on DVO breaches.

“We take domestic violence and the safety of women and children very seriously,” he said.

“In this circumstance we’d been working with the deceased and other agencies had been working with the deceased to manage their relationship and manage the circumstances of the breakdown of that relationship.

“A number of support agencies have been providing support to her and that will form part of the investigation and ultimately be part of a coronial file for the coroner.”
