Many thanks to NetGalley and Dutton for gifting me a digital ARC of this intriguing true crime book by Edward Humes - 5 stars!
Tanya Van Cuylenborg and Jay Cook were murdered during a trip to Seattle in the 1980s and detectives had few leads. There was only a single handprint on the outside of the young couple’s van. The detectives assumed Tanya and Jay were victims of a serial killer—but without any leads, the case seemed forever doomed. Detective Jim Scharf couldn't let it go; when he was assigned to the Cold Case Unit, he made it a focus. When new genetic DNA technology came into play, Detective Scharf chose the young couple's case to send for analysis.
While this is definitely a true crime book, discussing all the details of this crime over the 30-year period, it's much more. It's a look into how genetic DNA began and the pioneers who made it happen and made history. It also looks into all the political, legal, and societal ramifications of this new technology and what we risk and gain by uploading our DNA into these genetic databases. It's extremely well researched and fascinating - kudos to all law enforcement officers and genetic researchers who just want to bring a sense of closure and peace to these families.
