I Know Who You Are by Barbara Rae-Venter

A memoir-style true-crime account by a pioneering genetic genealogist who explains how she used public DNA databases and traditional genealogical research to build family trees, crack decades-old cold cases, and identify perpetrators, recounting the painstaking investigative process, key breakthroughs (including the identification of a notorious serial offender), and the human, legal, and ethical consequences as forensic genetics reshapes criminal investigation and privacy debates.
