The Debrief is joined by CeCe Moore, the pioneering genetic genealogist who helped turn a hobbyist's tool into one of the most powerful weapons in modern policing. CeCe explains what those consumer DNA tests are really telling you, how far back your family tree can genuinely be traced, and why some parts of the world are far better represented in the databases than others. The conversation digs into the hurdles of unpicking someone's ancestry, and how the same technology that reunites adoptees with birth parents is now cracking cold cases that sat untouched for decades. Then comes the harder question: where does personal privacy end and the pursuit of justice begin, when a distant cousin's spit sample can put a killer in handcuffs? CeCe also looks ahead to where AI takes this next, and reflects on how a career spent inside other people's DNA has reshaped the way she thinks about family, identity and truth itself.
