The discovery of Melissa Caddick's remains - more than three months after she vanished from her Sydney mansion - sent shockwaves around the nation. NSW Police Assistant Commissioner Mick Willing said today it was one of the most high-profile missing persons' cases he had worked on in his 30 years on the force as dozens of investigators worked to find the missing conwoman. Ms Caddick, 49, was accused of conning her friends and family out of more than $20 million through her fraudulent investment business Maliver Pty Ltd. Ms Caddick disappeared from her Dover Heights home in the early hours of November 12, hours after investigators from the Australian Securities and Investments Commission (ASIC) raided her house and told her she would need to hand in her passports the next morning.
