The Delphi Murders: 43 Seconds of Video That Took 7 Years to Match

The most important piece of evidence in the Delphi murders is 43 seconds long, and the person who recorded it was one of the victims.

On the afternoon of February 13, 2017, 14-year-old Liberty "Libby" German raised her phone on the Monon High Bridge outside Delphi, Indiana, and filmed the man walking toward her and her best friend. Head down. Hands in pockets. Blue jacket, jeans. Then the audio that an entire country would eventually be able to recite from memory:

"Guys. Down the hill."

Libby and 13-year-old Abigail "Abby" Williams were found the next day, about a quarter mile from the bridge, on the north bank of Deer Creek. Their throats had been cut. It would take five and a half years to arrest the man prosecutors said was on that recording — and he had been hiding in plain sight the entire time.

Background: an ordinary afternoon

Delphi is a town of about 3,000 people in Carroll County, Indiana. February 13, 2017, was an unseasonably warm school holiday, and Libby's older sister dropped the girls off near the trailhead of the Monon High Bridge Trail around 1:35 p.m. — a familiar walk they'd done before, ending at the abandoned railroad bridge that towers over Deer Creek.

At 2:07 p.m., Libby posted a photo of Abby walking the bridge planks. Sometime in the minutes after, she started recording the man behind them.

When the girls missed their 3:15 pickup and didn't answer their phones, the family began searching. By nightfall, volunteers and police were combing the woods. The bodies were found the next day, February 14, staged in a way investigators withheld from the public for years — a detail that would matter enormously at trial.

The evidence Libby left behind

Investigators have called Libby German a hero, and the record supports the word choice: she documented her own killer.

• The video captured the man's build, gait, clothing — and, critically, his voice. Police released a grainy still ("bridge guy") almost immediately, an audio clip of "down the hill" two months later, and the fuller video years after.
• The sketches. Two composite sketches were released — one in 2017 of an older-looking man, one in 2019 of a younger man — and the 2019 press conference pointedly told the killer, "We know this is about power to you… we believe you are hiding in plain sight." The two sketches, which looked like different people, fueled years of confusion and amateur theories.
• The unspent round. Between the girls' bodies, investigators found a single unfired .40-caliber cartridge. It had no fingerprints — but a cycled round carries tool marks from the gun that chambered it. That cartridge would sit in evidence for five years, waiting for a gun to compare it to.

Hiding in plain sight — literally

Here is the fact that makes Delphi unlike almost any other case we've covered: Richard Allen told police he was there — in 2017.

Days after the murders, Allen — a CVS pharmacy technician who lived in Delphi and had processed photo orders for people in town — voluntarily contacted authorities to say he'd been walking the trail that afternoon, wearing a blue jacket and jeans, and had seen three girls but nothing suspicious. The tip was interviewed, written up… and misfiled — labeled in a way that kept it from ever surfacing in the suspect pool.

For five years, while the town scrutinized every stranger and the internet accused a parade of innocent men, the self-reported man in the blue jacket filled prescriptions a few minutes from the bridge.

In September 2022, a volunteer file clerk reorganizing tip records found the sheet. Investigators re-interviewed Allen, searched his home that October, and seized a SIG Sauer P226 pistol in .40 caliber. Indiana State Police laboratory analysis concluded the unspent round found between the victims had been cycled through Allen's SIG — the forensic thread connecting the man from the misfiled tip to the ground between the bodies.

Richard Allen, then 50, was arrested on October 26, 2022.

The wait for trial: confessions and chaos

The two years between arrest and trial were among the most turbulent in recent criminal-justice memory:

• The confessions. Held in solitary at a state prison while awaiting trial — an extraordinary arrangement for a pretrial detainee — Allen made dozens of incriminating statements: to his wife and mother on recorded phone calls ("I did it. I killed Abby and Libby."), to prison staff, and to a psychologist. The defense argued the isolation had broken him psychologically — that a man in a mental-health crisis confessed to everything and anything. Prosecutors noted one confession included a detail matching the withheld crime-scene evidence.
• The Odinism theory. Allen's defense filed a bombshell memorandum alleging the girls were killed in a ritualistic sacrifice by adherents of a Norse pagan sect, naming alternative suspects. The judge barred the theory from trial as lacking an evidentiary nexus — a ruling now central to the appeal.
• The leaks, the disqualifications, the drama. Crime-scene photos leaked. Allen's defense attorneys were briefly forced off the case, then reinstated. The saga generated headlines for months before a jury ever heard evidence.

The trial: November 2024

The case was tried in Delphi with a jury bused in from Allen County (Fort Wayne), sequestered for the duration — media were barred from broadcasting, so the country followed through reporters' daily dispatches.

The state's case braided four strands: Allen's own 2017 statement placing himself on the trail in matching clothing; witnesses who saw "bridge guy"; the ballistics testimony on the unspent round; and the confessions — including the crime-scene detail prosecutors said only the killer would know. The defense attacked every strand: the ballistics discipline as junk science, the confessions as the product of psychological torture in solitary, the timeline as leaving room for someone else.

After roughly 19 hours of deliberation, the jury convicted Allen on all four counts — two counts of murder and two of felony murder. On December 20, 2024, he was sentenced to the maximum: 130 years.

At sentencing, the families finally spoke directly to him. Libby's grandfather, who had helped raise her, told the court the girls did more to solve the case than anyone — that his granddaughter's 43 seconds of courage caught the man the state spent five years missing.

The appeal: September 21, 2026

The case is not over. Allen's appellate team has asked the Indiana Court of Appeals to overturn everything, on three main grounds:

1. The search. The defense brief goes after the probable-cause affidavit sworn by the sheriff for the October 2022 search of Allen's home, arguing it was built on "deliberate falsehoods and material omissions" — including, they say, a statement that Allen had admitted wearing clothing matching "bridge guy," which they contend he never did. If the affidavit falls, the search falls; if the search falls, so does the seizure of the SIG Sauer and the ballistics match that anchored the case.
2. The confessions. They contend statements made by a pretrial detainee held in prolonged solitary confinement — "deeply ill," in "unprecedented confinement" — were involuntary under federal due process and under Indiana's distinctive constitutional ban on treating prisoners with "unnecessary rigor." A pretrial detainee housed in a maximum-security prison, they argue, produced confessions that were symptoms, not statements.
3. The defense he couldn't present. They argue that barring the alternative-perpetrator theory denied Allen his constitutional right to present a complete defense — that the jury convicted without ever hearing the story his lawyers wanted to tell.

The State of Indiana's answer brief, filed in March 2026, urges the court to let the convictions stand: the warrant was sound, the confessions voluntary and corroborated by a withheld crime-scene detail, and the excluded theory speculation without an evidentiary nexus.

The arguments happen Monday, September 21, 2026, at 10 a.m. — not in an ordinary appellate courtroom, but in the Supreme Court courtroom at the Indiana Statehouse, before a three-judge panel, with each side allotted 30 minutes. We've broken down what actually happens at an appellate oral argument, and the short version applies here: the questions the judges ask will be the first real signal of which pillars are in danger.

The stakes, mapped

• Search suppressed → the ballistics link to the unspent round likely goes with it → retrial with the state's physical case gutted.
• Confessions suppressed → retrial without the "only the killer would know" detail — but the 2017 self-report, the video, and the ballistics survive.
• Third-party ruling reversed → retrial where the defense finally presents its alternative-perpetrator theory to a jury.
• Affirmed on all grounds → expect a transfer petition to the Indiana Supreme Court, which takes only a fraction of such cases. If transfer is denied, the direct appeal is over and Allen's remaining paths narrow to post-conviction relief.

No ruling is expected for weeks to months after argument — realistically late 2026 or early 2027. The date is on the court dates tracker.

Why this case file matters

Every case leaves a record, but Delphi inverted the usual order: the record came first. The victim filmed the killer before the crime, the killer reported himself to police within days, and the physical evidence sat matched-but-unmatched in an evidence room for five years. Nothing about the case was hidden. All of it was simply unconnected.

It took a misfiled tip sheet, a volunteer clerk, and one unspent cartridge to finally close the loop — and a 14-year-old's steady hand to make any of it possible.

Case status as of this writing: convicted on all counts and serving 130 years; direct appeal pending, with oral arguments before the Indiana Court of Appeals scheduled for September 21, 2026. Allen maintains his innocence through counsel on appeal.
