Isabella Allen from the Australian Securities and Investments Commission led the formal investigation from September 8, 2020 into Ms Caddick's Ponzi scheme operated under her fake company Maliver.
The conwoman purported to be investing her victims' wealth by appearing to set up CommSec trading accounts and forging documents to claim she was generating profits through capital growth and shares.
She preyed on mostly friends and family and stole up to $30 million between 2013 and 2020, counsel assisting Jason Downing SC has told the inquest.
A week after the corporate watchdog began its investigation into the misappropriation of funds Ms Caddick booked shredding services for document destruction at her home address.
The last verified sighting of Ms Caddick was when ASIC and the Australian Federal Police raided her Dover Heights mansion on November 11, 2020.
Ms Caddick's mother Barbara Grimley holds ASIC responsible for her daughter's suspected death saying she was highly distressed during the raid and was not allowed any food or water.
The AFP's Constable Amelia Griffen shadowed Ms Caddick for the majority of the 12-hour search and confirmed she did make herself food and was allowed to leave the property whenever she wished.
Her husband Anthony Koletti phoned in the 49-year-old as missing some 30 hours after he says she walked out of their home for the last time on November 12 about 5.30am to "go for a jog".
Mr Koletti is due to give evidence following Ms Allen.
What Mr Koletti knew about Ms Caddick's disappearance has been the source of intense scrutiny in the first week of his wife's inquest.
The part-time hairdresser and DJ told police he was too busy working from home to make a statement in person and was subsequently visited at his home where he gave "conflicting stories," Sergeant Trent Riley told the coroner.
In February 2021 Ms Caddick's decomposing foot encased in an Asics shoe washed ashore at Bournda Beach on the NSW south coast, about 400km south of Sydney.
The inquest before Deputy State Coroner Elizabeth Ryan is set to resume on Monday after a week's break.
