Dee - delighting in the Desert :)'s Reviews > I Know Who You Are: How an Amateur DNA Sleuth Unmasked the Golden State Killer and Changed Crime Fighting Forever

4.5 stars rounded down for this riveting N/F written by the woman who got the Golden State Killer in just 63 days using investigative genetic genealogy, after a multi-decades long and fruitless investigation had stalled out. The author is very self-effacing and seems quite genuine. I consider this one part of the “GSK Trilogy” with M. McNamara’s “I’ll Be Gone in the Dark” & Paul Hole’s “Unmasked”, both so great, before it.
