On February 13, 2017, two Indiana teenagers, Abigail Williams, 13, and Liberty German, 14, went for a walk in the woods near the abandoned Monon High Bridge.

They never returned home.

Their bodies were discovered on Valentine's Day morning, sparking a torrent of news coverage and social media speculation that engrossed the attention of people around the world.

A grainy photo of the suspected killer walking across the bridge and a chilling cellphone recording of his voice saying "down the hill" captured the public's attention. Numerous possible suspects were brought to the attention of the authorities but dismissed, leaving everyone wondering who could have committed such a heinous crime.

Author Nic Edwards, host of the wildly popular True Crime Garage podcast, was fascinated by the case and for years conducted his own extensive research and commentary. As such he was able to dissect the investigation that included an extensive list of possible suspects, such as a hatchet-wielding lunatic, a kidnapper with unusual tattoos, a murderous pastor, a rapist, and a father and son catfishing team.

Then in late October 2022, local pharmacy technician Richard Allen was charged with the murders. His arrest raised multiple questions about how he was able to evade law enforcement for so long and what motivated him to commit such a horrific crime.

In The Delphi Murders: The Quest To Find ‘The Man on the Bridge’, Edwards and his best-selling coauthor Brian Whitney (You Have a Very Soft Voice, Susan) provide a detailed account of the investigation from the day the girls’ bodies were found to the events leading up to Allen's arrest, and unique insight into the minds of the killer and those who worked tirelessly to bring him to justice.
