Sydney, Australia - The mysterious death of a prominent businesswoman who vanished without a trace three months ago is making headlines in Australia.

On Sunday, campers found a sneaker with the remains of a human foot on Bournda Beach about 250 miles south of Sydney, according to Yahoo! News.

On Friday, the police confirmed that according to DNA samples, the foot was that of Melissa Caddick, a 49-year-old woman who was suspected of defrauding investors out of millions of dollars.

The case caused a stir Down Under, with Caddick last seen at her luxury villa in Dover Heights, a coastal suburb of Sydney, on November 12.

Her family initially thought she had gone for a morning jog – she had left her phone, wallet, and keys behind. Two days later, her husband reported Caddick missing.

Shortly before her disappearance, investigators from the Australian regulator ASIC had searched her home in connection with the fraud allegations, and her accounts had also been frozen to prevent her from leaving the country.

Caddick reportedly bilked numerous people out of large sums of money through her company and an unlicensed investment scheme in order to fund her extravagant lifestyle.

According to a police spokesperson, the sports shoe with the foot had been in the water for some time and has now washed up on the beach. "It remains a mystery as to when and how she came into the water," the assistant commissioner of the New South Wales Police told reporters.

It was also possible that Caddick had taken her own life, he said, adding that all directions were being investigated.
