The mother and brother of Sydney fraudster Melissa Caddick want to give evidence at an inquest into her suspected death because they feel their "voice isn't being heard", a court has been told.
Ms Caddick vanished in November 2020 as the corporate watchdog, the Australian Investment and Securities Commission (ASIC), investigated her alleged Ponzi scheme which involved fraud of between $20-$30 million.
Three months later, a running shoe containing the 49-year-old's decomposing foot washed up on Bournda Beach, on the NSW south coast.
On the fourth day of an inquest into Ms Caddick's suspected death, Judy Swan, the lawyer representing her husband Anthony Koletti, told the court Ms Caddick's mother Barbara Grimley and brother Adam Grimley wish to give evidence.
"They have expressed their concern that their voice isn't being heard," Ms Swan said.
She explained the request was a result of the contents of Monday's opening address.
"They are concerned about the nuances made by Counsel Assisting in relation to their son-in-law and their brother-in-law," Ms Swan said.
They are seeking to give evidence about Mr Koletti and Ms Caddick, the court heard.
Ms Swan was not acting for the Grimleys but said she was passing on their concerns.
Counsel Assisting Jason Downing SC said the material in the opening had been available in a brief of evidence for some months, giving parties an opportunity to be aware of it.
Deputy State Coroner Elizabeth Ryan set a timetable for material from the Grimleys to be produced for consideration.
A police supervisor, Detective Inspector Gretchen Atkins, told the inquest she was concerned the first officer in charge of the investigation into her disappearance had narrowed his focus that Ms Caddick had "gone to ground".
"Did you have any concern that perhaps Detective Sergeant Michael Kyneur had a preconceived idea or theory?" Counsel Assisting Jason Downing SC asked.
"Yes," Detective Inspector Atkins said.
"Your concern was, in effect, Detective Inspector Michael Kyneur had narrowed his focus, that she had gone to ground"
"Yes."
Detective Inspector Atkins also told the inquest that she was surprised an affidavit written by ASIC to obtain a search warrant wasn't sought by NSW Police til three months after she went missing.
The 92-page document was served on Ms Caddick when they raided her home on November 11.
It details the allegations against Ms Caddick, as well as details of people alleging the significant fraud she'd committed.
The inquest heard on Wednesday that Detective Sergeant Michael Kyneur, didn't ever ask to see the document.
"Why would I be privy to that? It wasn't made for a policing purpose." he said.
"Do you believe there would have been a benefit in having (the affidavit) in the first week while Detective Sergeant Kyneur was OIC?," Counsel Assisting Jason Downing asked.
"Yes." Detective Inspector Atkins said.
The affidavit was only sought by NSW Police on February 1.
"Does that surprise you?" "Yes."
"Would you expect it would have been obtained and reviewed before then?" "Yes."
The inquest also heard Detective Sergeant Glen Browne from the Missing Persons Unit expressed concerns to Detective Inspector Atkins that the investigation was "progressing slowly."
Earlier, the court heard police investigating Ms Caddick's disappearance considered an experiment involving dead pigs fitted with tracking devices — and some wearing running shoes — being thrown into the ocean.
The inquest has heard from Detective Sergeant Steven Morgan, who acted as a Homicide Squad consultant for six months until September 2021.
Documents detailing his activities in relation to the investigation contain reference to the proposed experiment.
The court heard it was to involve several pig carcasses being cast into the ocean after being fitted with tracking devices.
Some were to also be fitted with running shoes.
One of the aims was to ascertain the behaviour of sharks, the inquest was told.
Asked whether that experiment ever took place, Detective Sergeant Morgan replied: "I don't know."
He said it was commissioned by forensics.
"I imagine one of the managers there may be able to assist."
The court also heard Detective Sergeant Morgan's notes contained information that Ms Caddick had insurance policies in place which provided cover in the event of her suicide.
The court has heard an autopsy was unable to determine if the foot was separated as a result of blunt force, sharp force, or decomposition.
The inquest, before Deputy State Coroner Elizabeth Ryan, continues.
