"The amateur DNA sleuth who solved one of the most infamous cold cases in American history-the Golden State Killer crime spree-tells the incredible true story of how she did it, and explains how her methods have forever changed criminal investigations. In the span of just a few years, Barbara Rae-Venter went from researching her family history as a retiree to finding a serial killer who had baffled law enforcement for decades. I Know Who You Are tracks her improbable journey to becoming the nation's leading authority in investigative genetic genealogy, and to identifying the Golden State Killer-who had evaded authorities for forty-four years-in just sixty-three days. Rae-Venter also details other extraordinary cases that she has worked on, from the first criminal cold case she ever cracked-uncovering the long-lost identity of a child abductee-to the heartbreaking case of the Billboard Boy, which began with unidentified remains dumped along a North Carolina highway."--
