About this episode
Kevin Docherty shares the story of his sister's disappearance and the ongoing search for answers over 47 years.
A twin brother's 47-year fight for answers, suspicious letters and a new witness who may hold the key to where Kay Docherty is buried. In this episode, Kevin Docherty shares the heartbreaking story of his sister Kay Docherty, who vanished alongside her friend Toni Cavanagh in 1979. Nearly five decades on, Kevin recalls the night they disappeared, the suspicious letters sent to their families days later, and the long fight for answers after police initially treated the case as a runaway. He also reveals new information from a recently emerged witness that may not only point to Ivan Milat, but to a potential burial site that has never been searched.
