The foot of a missing Sydney woman, who disappeared from her home last year, was found on the New South Wales Coast on Sunday.
Melissa Caddick was presumed dead after she disappeared from her Dover Heights home on November 12.
The 49-year-old did not take her mobile phone, wallet, or keys when she left for a morning run before sunrise.
NSW Police Assistant Commissioner Mick Willing says analysis using DNA from Caddick's toothbrush matched the foot found inside a shoe.
"A shoe was located on the shoreline of the Bournda National Park by campers. Within that shoe were the remains of a human foot," Assistant Commissioner Willing said in a media conference.
"Offshore drift modelling raised the possibility that an object or body that entered the water around the day in the Dover Heights area could drift as far south as the Bermagui area.
"Exactly how Melissa came to enter the water is still a mystery and will be subject to ongoing investigation by the strike force team."
The 49-year-old is suspected of allegedly stealing "tens of millions" of dollars from investment clients.
The Australian Federal Police (AFP) raided her home as part of an investigation, days before she disappeared.
Assistant Commissioner Willing says police are not ruling out the possibility of suicide.
"Clearly the circumstances of Melissa's disappearance has been distressing for many people including her alleged victims and of course her family and friends.
"Police have always kept an open mind in relation to what the circumstances were for her disappearance including the fact that Melissa may have taken her own life.
"However, investigations will be ongoing."
