"You'd need the population of 123 million planet Earths to have a large enough population for it to be likely that two people share the same DNA profile"
This crime was unsolved for 30 years until genetic genealogy traced the DNA to a suspect.
Although it's closing ice cold cases I was surprised to learn the war between the leaders of the genealogy community involving privacy concerns. The evolution of DNA genealogy depicted was fascinating

Spotted in the library parking lot.

This is the case which served as the hallmark of DNA genealogy used to solve crimes. It seemed to be happenstance that a woman CeCe Moore in California began investigating genetic genealogy not realizing that she was about to fall into a rabbit hole. Since then, she was able to lend her knowledge of this technology to solve crimes. That's where Detective Jim Scharf comes in to solve a cold case of a double murder: Tanya Van Cuylenborg /Jay Cook.

This was an interesting, informative look at the first criminal trial using genetic genealogy as its primary evidence. The cold case is a horrific murder of two young Canadians on a trip to Washington State. This book not only details the crime, but also delves into the privacy concerns around public and private DNA databases, and a history of the development of forensic genetic genealogy, especially the work of CeCe Moore and Parabon.

This was two related subjects in one-the story of a 1887 murder and the present day advanced in DNA and genetic generally.

I loved this book and definitely have food for thought about DNA and those pay for answers about ancestry i.e. 23&Me or Ancestry.com.

Recommended if your interested in forensic genealogy or true crime.

Used my free space to read this fascinating book about the first cold case that was solved using genetic genealogy techniques to identify a suspect with DNA and family trees. As an amateur genealogist who has been researching my own family since the days before the internet, this was right up my alley.

Really fascinating. The story of a 1987 cold case investigation and how genetic genealogy played a role in solving this case and others. He also examines the continuing debate surrounding this issue.

If true crime is your thing, you should read this book. This book is about how a cold case double murder was solved using genetic genealogy, which is the process that was used to track down the killer of the four students in Idaho and also the Golden State Killer. The writing is terrific and the story is a page turner. Five big stars.
