Kay Docherty was 15 years old when she vanished on July 1979. She'd told her mum she was going to babysit at a friend's place. Her twin brother Kevin was supposed to pick her up at nine. He never got the chance.
Forty-six years later, her twin brother Kevin Docherty, is still searching for answers — and still fighting to be heard. Adam talks to Kevin Docherty about the night Kay disappeared, the letters that were never properly investigated, the toll of 46 years of unanswered questions, and why this inquiry may be the family's last real chance at the truth.
