Further evidence from NSW Police officers will conclude an inquest into the disappearance of Sydney fraudster Melissa Caddick.
Two days after corporate watchdog ASIC and Australian Federal Police officers raided her Dover Heights home, the 49-year-old was reported missing on November 13, 2020, by her husband Anthony Koletti.
Detective Sergeant Michael Kyneur, initially the officer-in-charge of the investigation into her disappearance, said Mr Koletti "always appeared confused".
"He kept on telling me she was going to show up at court and that she had a lot of cash, I think he told me," Det Sgt Kyneur told the inquiry on Monday.
The investigation "did snowball very quickly" after a press conference held a week after Caddick was reported missing.
Det Sgt Kyneur notified the homicide squad the next day and was no longer the officer-in-charge shortly after.
Detective Inspector Gretchen Atkins and Detective Sergeant Michael Foscholo are scheduled to give further evidence on Tuesday.
Det Insp Atkins told the inquiry in September that Mr Koletti was not considered a suspect.
"There'd been searches at the house, there'd been conversations with Mr Koletti ... there was no evidence of homicide," Det Insp Atkins said.
Detective Chief Inspector Glen Browne, manager of the NSW missing persons registry when Caddick vanished, said on Monday he found out about her disappearance four days after the initial report.
In a conversation with Det Sgt Kyneur, Det Insp Browne reminded him to keep an open mind.
"I got a sense from the conversation that the primary line of inquiry is that Melissa was avoiding being located," Det Insp Browne said.
The theory was "being given more importance than others".
Caddick defrauded family and friends of between $20 million-$30 million in a Ponzi scheme before her disappearance.
Her decomposing foot washed up in a running shoe on the NSW south coast's Bournda Beach in February 2021, some 350 kilometres from the home Caddick was last seen at in Sydney's eastern suburbs.
Det Insp Browne said an experiment the inquiry previously heard about, involving pig carcasses being tracked in the water, predated Caddick's disappearance and was never conducted.
There were concerns about what the tracking devices could do to protected great white sharks, he said on Monday.
