In this compelling book, Ashley Spence shares her powerful journey from survivor to advocate, revealing how forensic DNA can change lives, transform justice, and prevent crimes before they happen. At just 19, Ashley endured a brutal assault that nearly claimed her life. For years, her attacker remained unknown-until DNA evidence brought him to justice, ensuring he would spend nearly 138 years behind bars.

Now, as a mother and the founder of the DNA Justice Project, Ashley dedicates her life to advocating for laws that expand the use of forensic DNA technology, strengthen national databases, and secure funding for life-saving programs. This book offers hope and healing for victims, and is also an inside look at the power of DNA to create policy change, provide justice for victims, and prevent future tragedies.

Part memoir, part call to action, Silent Witness is a testament to the resilience of the human spirit and the transformative potential of science to shape a safer world.
