Shadow of the Bridge

The Delphi Murders and the Dark Side of the American Heartland

By: Aine Cain, Kevin Greenlee

Narrated by: Kevin Greenlee

The haunting account of the Delphi Murders, a double-murder case that has held an unrelenting grip on the American heartland for over six years.

On February 13, 2017, two teenage friends went for a walk in the woods just outside the small city of Delphi, Indiana. They should have been safe—but Liberty German and Abigail Williams never made it home. The next day, searchers found their bodies in a clearing. The two girls had been brutally murdered. Incredibly, in the final moments of her life, Liberty somehow managed to capture a video of the man who would soon murder her and her friend. This blurry recording showed a man lumbering toward the girls and then gruffly commanding them to go “down the hill.” A fascinated public obsessed over those clues. Speculation about the killer’s identity ran rampant on social media. Meanwhile, a sprawling law enforcement investigation led to some of the darkest corners of the heartland. Still, the case remained unsolved for years.

Everything changed in October 2022 when authorities announced the arrest of Delphi resident Richard Allen. But as the case began to make its way through the justice system, many began to question whether the small community had what it took to prosecute the case. They also wondered whether or not the police had even arrested the right man. Investigators, officials, prosecutors, and the defense attorneys found themselves stuck in an unprecedented firestorm of online controversy and subterfuge, with so-called internet sleuths hyping up conspiracy theories and trading leaks.

Now, Áine Cain and Kevin Greenlee, the investigative team behind a series of bombshell reports on the case have put forth the only definitive account of the entire investigation. Shadow of the Bridge: The Delphi Murders and the Dark Side of the American Heartland goes deeper and offers more detail than what was shared on the popular Murder Sheet podcast, answering many of the questions that have haunted so many since the deaths of Libby and Abby. Most importantly, in working closely with the German and Williams families, Cain and Greenlee tell the stories of who these two warm, bright, and promising girls were to all who cared for them. With rigorous research and captivating prose, Shadow of the Bridge is a powerful narrative of a complicated, twisting story of tragedy and a community's determination to see justice.

A thorough recounting

I followed this case for years, as my imagination, like so many others’, was caught by Libby’s brave act of filming her killer, and Abby managing to hide the phone before her death. The authors are also the hosts of The Murder Sheet podcast, an attorney and a journalist who exhibited their own bravery with their relentless unmasking of the oftentimes bewildering actions and behavior of various people associated with the case. Through threats and harassment, they’ve produced arguably the definitive book on the case, leaving no detail unrevealed. Kevin Greenlee narrates the book, and does so with his characteristic warmth and care. Five stars, for sure.

Thorough and engaging

Shadow of the Bridge is a thorough guide to everything-every piece- of the tragic Delphi murders in Delphi, Indiana in 2017. Kevin and Áine do a wonderful job of recounting the story in such detail that you feel like you’re in the woods with the investigators looking for the girls. Thorough research and due diligence went in to this book and it is evident in the way the book is written to reflect actual true events of the murders, the investigation, and the trial of Richard Allen.

For years to come, this will be the book at the top of the reference list when discussing the Delphi Murders. Kudos to Kevin Greenlee and Áine Cain.

Factual representation of events.

Thorough and Well Researched

Having followed this case for years, this is a very detailed, comprehensive telling of the deaths, investigation and justice for Abby & Libby. The authors of this book have devoted hundreds of hours to covering this story. They have covered it with compassion and integrity. I was so happy when I learned that Kevin Greenlee would be narrating the books for Audible. I follow his podcast so it was like an old friend reading it to me and I could focus in on the words. I recommend this to anyone wanting to know about the Delphi murders.

Great insights into Abby's and Libby's lives and the fight for justice
