Mystery Letters & Ivan Milat: Kay Docherty's 47-Year-Old Cold Case

47 years ago, 15-year-old twin sister Kay Docherty and her friend Toni Kavanagh vanished on a Friday night out in Wollongong. They were never seen again. In this powerful episode of Motive & Method, Kay’s twin brother, Kevin Docherty, shares his family's story after giving emotional evidence at the New South Wales Parliamentary Inquiry into missing persons cold cases. 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. _______________________________________ CHAPTERS: 00:00 Where is Kay Docherty? 00:52 The Parliamentary Inquiry 01:35 What happened July 27, 1979? 06:37 The Police Response 08:44 Did Kay really send the letters? 11:54 The impact on the family 13:54 A Mother’s Secret Journals 15:42 When the System Failed 17:38 An Ivan Milat Connection? 20:03 New Witness Lead 23:02 Hope for Resolution
