“Thought-provoking true-crime thriller…the book raises urgent questions of balancing public and private good that we’ll likely be dealing with as long as the title implies.”—Wall Street Journal

After 30 years, Detective Jim Scharf arrested a teenage couple's murderer—and exposed a looming battle between the pursuit of justice and the right to privacy.

When Tanya Van Cuylenborg and Jay Cook were murdered during a trip to Seattle in the 1980s, detectives had few leads. The murder weapon was missing. No one witnessed any suspicious activity. And 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.

In deep-freeze, long-term storage, biological evidence from the crime scenes sat waiting. Meanwhile, California resident CeCe Moore began her lifetime fascination with genetic genealogy. As DNA testing companies rapidly grew in popularity, she discovered another use for the technology: solving crimes. When Detective Jim Scharf decided to send the case’s decades-old DNA to Parabon NanoLabs, he hoped he would bring closure to the Van Cuylenborg and Cook families. He didn't know that he and Moore would make history.

Anyone can submit a saliva sample to learn about their ancestry. But what happens after the results of these tests are uploaded to the internet? As lawyers, policymakers, and police officers fight over questions of consent and privacy, the implications of Scharf’s case become ever clearer. Approximately 250,000 murders in the United States remain unsolved today. We have the tools to catch many of these killers—but what is the cost?

—Bookpage (starred review)

“A well-paced true-crime procedural that offers new twists on old methods of police work.”
Kirkus

“An excellent addition to any true crime collection, this one is sure to intrigue readers who are interested in delving deeper into the hows and whys of solving cold cases.”
Library Journal

“Some detectives never give up, and in this expert retelling, you'll follow Jim Scharf as he attempts to crack the coldest of cases: A golden young couple abducted and murdered in Washington state in 1987, with almost no clues left behind. This book is that rare thing, terrifying true crime told with a beating heart.” 
Maureen Callahan, New York Times bestselling author of American Predator

“In this brilliantly told, addictively readable book, Edward Humes reminds us that the term “cold case” is misleading, that unsolved murders simmer for decades with angry life and grief and the long-shadow of justice denied. And he also reminds us to hope that the answers to our most stubborn mysteries can yet be found if we simply refuse to give up on them.” 
Deborah Blum, New York Times bestselling author of The Poisoner's Handbook: Murder and the Birth of Forensic Medicine in Jazz-Age New York

The Forever Witness is a remarkable achievement in true crime reporting, as Edward Humes brilliantly guides readers through a cold case investigation that’s smart, suspenseful, and on the cutting edge of forensic science. This book will keep you reading well into the night.”
Gilbert King, Pulitzer-prize winning author of Beneath a Ruthless Sun and Devil in the Grove

“A story within a story within a story—once you think you know what The Forever Witness by Edward Humes is about, Humes takes you deeper. It is not only a story of the tragic murders of two young people—but about the tale their bodies told, and how, after decades, that tale was able to come to light. Layered and informative, compassionate and analytical, this book picks up where Michelle McNamara's I'll Be Gone in the Dark leaves off, explaining the miracle that is genetic genealogy as well as the ethical quagmire that surrounds it, while also offering a dignified eulogy to two lives violently, monstrously cut short.” 
Rachel Rear, author of Catch the Sparrow

“Ed Humes is not a fancy writer, and I mean that as a compliment.  He does not write for the applause of literary reviewers or book critics.  He writes for smart readers.  He is a gifted storyteller, an absolute master of the narrative.  The Forever Witness, the story of a kidnapping and murder, seizes you on the first page and holds you captive until the end.”
Gene Weingarten, two-time Pulitzer Prize winner for feature writing, Washington Post journalist and author of One Day

“Top-notch, must-read true crime. Edward Humes has crafted a brilliant and riveting account of a haunting cold case, a relentless detective, and the birth of a cutting-edge forensic tool.” 
Dean Jobb, author of The Case of the Murderous Dr. Cream and Empire of Deception, and professor in the MFA in Creative Nonfiction program at the University of King’s College

The Forever Witness is one of the best true crime books I’ve ever read—a riveting page turner that also made me so much smarter. With his deep and empathetic reporting, Humes manages to illuminate both the vivid history of a cold case and the complex future of criminology and genealogy.” 
Eli Saslow, Pulitzer Prize winner, Washington Post journalist, and author of Rising Out of Hatred

The Forever Witness is a nuanced examination of the role of genetic genealogy in criminal investigations, told through the wrenching, personal story of a horrific double murder left unsolved for decades. Humes approaches his subject with intelligence and probing curiosity, and the result is a fascinating study of the newest frontiers in information and DNA science.”
