This is the first true crime book I have read as an adult, and the only reason I chose it was for the genetic genealogy aspect of the story. We had a huge debate about the use of relative DNA to catch the Golden State Killer in our genealogy group. I was really interested to learn about how the police and CeCe Moore was able to use DNA to catch the killer in a thirty year cold case. A very captivating read. I couldn’t put it down.
