On a cold February afternoon in 2017, Liberty German and Abigail Williams went for a walk. They were just kids. It was a rare warm day in Delphi, Indiana, the kind of weather that coaxes everyone outside after a long winter. They headed to the Monon High Bridge, a local landmark that sits sixty feet above Deer Creek. It’s rusted, skeletal, and honestly, a bit intimidating if you aren't a fan of heights.
They never came home.
For years, the case of the girls on the high bridge felt like a ghost story that wouldn't end. We had the video. We had the audio. Libby German was smart enough—brave enough—to hit record on her phone when a stranger started following them. We all heard that gravelly voice say, "Down the hill." We all saw the grainy image of a man in a blue jacket and jeans, hands stuffed in his pockets, walking with a specific, heavy gait across the railroad ties. But for over five years, that man was just a shadow.
The Evidence That Sat in Plain Sight
It’s frustrating to think about now. Richard Allen, the man eventually charged and convicted, wasn't some drifter from three states away. He lived right there. He worked at the local CVS. He probably processed photos for people or sold them over-the-counter meds while the whole town was draped in "Abby and Libby" memorial ribbons.
The breakthrough didn't come from some high-tech satellite or a secret witness. It came from a clerical oversight and a re-examination of early interviews. Back in 2017, Allen actually talked to a conservation officer. He admitted he was on the trail that day. He said he saw three "juveniles" and was watching fish. But because of a filing error—some call it a "lost" tip—his name didn't resurface at the top of the pile for years.
When investigators finally circled back to him in 2022, things moved fast. They found a bullet. Specifically, an unspent .40 caliber round discovered between the girls' bodies. Using forensic ballistics, examiners linked that specific round to a Sig Sauer P226 owned by Allen. They claimed the extraction marks on the brass matched his gun perfectly.

Why the High Bridge Case Haunted the Public
The sheer brazenness of the crime is what kept people awake at night. This wasn't a dark alleyway at 3:00 AM. It was broad daylight.
The girls on the high bridge were victims of a predator who seemed to know the terrain better than anyone else. The Monon High Bridge is a "dead end" in a way; once you get out to the middle, there isn't an easy way off if someone is blocking your path. It’s a narrow, rickety trap.
During the trial, the public learned about the "confessions." While in prison awaiting trial, Allen reportedly confessed to the murders dozens of times over the phone to his wife and mother. His defense argued these were the ramblings of a man broken by solitary confinement—a "psychotic break," they called it. But the jury didn't buy it. The detail in those recordings, combined with the video Libby took, created a timeline that simply didn't leave room for anyone else.
The Role of Digital Sleuthing and "Delphi Logic"
You can't talk about capturing their killer without mentioning the internet. This case birthed an entire subculture of true crime followers. Some were helpful; many were not.
People spent years dissecting every pixel of the "Bridge Guy" video. They looked at the way his jacket bunched up, wondering if he was carrying a weapon or a kit. They analyzed the "Down the hill" audio until the words lost meaning. The problem with this kind of intense public scrutiny is that it often leads to "tunnel vision."

For a long time, rumors swirled about other suspects. Names like Logan, Kline, and Nations were dragged through the mud of social media. This is the danger of high-profile unsolved cases. While the internet was busy chasing shadows and complex conspiracies involving "catfishing" profiles like "anthony_shots," the real killer was just a regular guy living a quiet life less than two miles from the crime scene.
A Brutal Reality: The Trial and the Verdict
The trial in late 2024 was grueling. It wasn't the "CSI" episode people expected. It was a messy, emotional, and technically dense battle over toolmarks and mental health.
The prosecution leaned heavily on those prison confessions. They played them for the jury—raw, desperate, and incriminating. Richard Allen was found guilty on all counts: two counts of murder and two counts of felony murder.
Wait. Why the different counts? In Indiana, felony murder basically means someone died while you were committing another felony (like kidnapping). It gave the jury multiple ways to find him responsible for the deaths of Abby and Libby.
The defense tried to point toward "Odinism" and ritualistic killings, suggesting a group of people was involved. They pointed to the way the bodies were posed and the sticks placed on them. It was a wild theory that garnered a lot of headlines, but the judge restricted how much of it could be presented. Ultimately, the physical evidence—the gun and the video—outweighed the more "out there" theories.

What We Learned from Delphi
The capture of the killer of the girls on the high bridge changed how small-town murders are investigated. It showed that technology is a double-edged sword. Libby’s phone gave us the evidence, but the sheer volume of digital tips nearly drowned the investigation.
Basically, the "Delphi Murders" taught us that the most obvious person is sometimes the one you've already talked to. It taught us that "unspent rounds" can be as telling as a fingerprint. And most of all, it showed the world that two young girls were brave enough to record their own ending, ensuring that their killer couldn't hide forever.
Justice in Delphi wasn't swift. It was a slow, painful crawl. But it happened.
Actionable Insights for Following Cold Cases:
- Support Local Reporting: In cases like Delphi, local journalists (like those from the Indianapolis Star or Carroll County Comet) often have better context than national "parachute" reporters.
- Understand Ballistics: If you're following criminal trials, learn the difference between "class characteristics" and "individual characteristics" in forensic toolmark identification. It’s often the crux of the case.
- Report, Don't Speculate: If you have information on a case, give it to the FBI or local police, not a Facebook group. The "noise" created by amateur sleuths can actually delay justice by burying real leads.
- Respect the Families: Remember that behind every "viral" crime story are families like the Germans and the Williams who have to live through the graphic details being discussed globally.
