Cracking an 'unsolvable' double murder

A crime scene with nothing in it. A community that wouldn't talk. A suspect who turned out to be the wrong man. And a seven-year-old girl lying dead beside her father. The murders of Tony Byfield and his daughter Toni-Ann were Neil's first case as a Senior Investigating Officer. More than two decades on, he still describes it as the most famous of his career. In this episode, he takes Andy through it from the moment the phone rang: what he walked into, why the early breakthrough collapsed, and what it felt like to lead an investigation that a lot of people had quietly written off. Neil also reveals the parts of this story that never made the headlines. Why Crimewatch turned the appeal down. What a serious case review later concluded about the state's failure to protect Toni-Ann. And the moment the silence finally broke: a march through Kensal Rise, an anniversary appeal, and a single phone call that changed everything. Then Andy and Neil turn to Operation Trident, the unit this investigation fell under. What was Trident actually set up to do? Why did the killing of a child become so important to it? And if community trust is what cracked this case, what could the police still learn from it today?
