Delphi Murders Theories and Evidence: What Do We Really Know About the Abby and Libby Case?
Posted: September 16, 2025
Theories and Evidence
The Delphi murders have fueled years of speculation, with countless Delphi murder theories about who was responsible and what really happened that day on the Monon High Bridge. From early suspicions and witness tips to confessions and controversial claims made in court, the Delphi murder case has been shaped as much by Delphi case evidence as by unanswered questions. In this section, we’ll break down the key pieces of evidence investigators relied on, along with the most widely discussed Delphi murder theories that have surrounded the case since 2017.
Just Tuning In?
Just tuning in? You can catch up on everything we’ve covered so far in our deep dive into the Delphi murder investigation:
Lost, Misdirected, Phone Died, or Friends?
These were among the first explanations that came to mind when the girls hadn’t turned up. They were 13 and 14 years old and didn’t have the best sense of direction, so getting lost was something that could easily have happened. Other explanations included their phone dying or running into other friends on the trails. They all had the day off from school, so this was an easy, no-panic explanation that family and friends initially jumped to — until it started to get dark and the girls weren’t back. Libby was afraid of the dark, which became a red flag pushing the Delphi murder investigation into a more serious status.
Richard Allen
Richard Allen is a local who worked in the area and was on the trails that day. He admitted he was there, and witnesses saw him. But here’s what stands out: five female witnesses reported seeing one man on the trail who could have been “Bridge Guy.” Richard Allen, when interviewed, didn’t mention seeing another man, only the females. By process of elimination, there was only one man seen on the trails that day.
The Bridge Guy video matched Allen’s appearance. He also described the clothing he was wearing in an interview — blue parka, jeans, and a hat — which aligned with the video. The audio captured a man saying “down the hill,” which became a key piece of the Delphi murder case evidence. Some argue voice recordings are unreliable, but hearing the video side by side with snippets of Allen’s interview is eerie and hard to dismiss.
He Confessed
Allen was interviewed repeatedly, including while incarcerated. Over the years, he reportedly confessed over 60 times to 24 different people, including his wife. She quickly corrected him, stating he was not capable of doing something like this and that without his medication he couldn’t be saying things like that.
Rumors surfaced of Allen being mistreated in prison, losing weight, and looking sickly — a stark difference from when he first entered. Some argue that since he was not found guilty immediately, he should never have been in prison in the first place. Stress, change in environment, lack of medication, coercion, and fear can all impact someone’s mind and can create false confessions. Having more confessions doesn’t automatically make them true. Investigators in this case held back much information from the public, so when they believed they had a killer, they could confirm the details privately to ensure accuracy.
Gun Casing
An unspent gun casing was found at the scene where the girls were discovered. When a bullet is fired, marks called lands and grooves are left on the bullet, which can be matched to a specific gun. It was confirmed that the bullet, though unspent, matched a Sig Sauer gun registered to Richard Allen. Allen admitted to owning the gun and not allowing others to use it.
How the casing ended up there is unclear — there were no bullet wounds on the bodies, and the shell was unspent. It could have been carried accidentally, much like children collect unusual items. One body was nude, the other wore the other’s clothing. If the casing was in a pocket, it could have fallen out at the scene. This might also relate to why cutting was involved — perhaps the gun didn’t go off.
Box Cutter Found on His Property
The girls died from knife-like wounds. Their throats were cut and they had stab wounds. A box cutter found at Allen’s home matched the wounds’ patterns.
While this is significant, one item alone isn’t proof. Many people have knives or box cutters at home without committing crimes. But combined with other Delphi case evidence, it adds context to the investigation.
So What’s the Motive?
No single piece of evidence proves Allen did this. However, the combination of evidence tells a story. According to people he confessed to, Allen admitted the crime was sexual in nature — intending to rape the girls but deciding to kill them instead when spooked. There were no clear indicators of sexual assault, but the arrangement of clothing and nudity indicates it may have played a role. Likely, it was a mix of sexual fantasy, power, and control.
It’s important to note that Allen’s behavior and statements fluctuated in prison, so the confessions are inconsistent. Skepticism is warranted when basing theories solely on confessions.
Kagen Klein
Kagen Klein, an online predator using the alias Anthony_shots, lured girls with money and prestige, influencing them to send nude photos. His home was raided in 2020, but he was not connected to Abby and Libby’s murders. He denied meeting them, although this behavior is disturbing.
Ron Logan
Ron Logan owned the land where the girls were found. His behavior was concerning — revisiting the site repeatedly with others, possibly observing reactions. He had a criminal record, lied about his alibi, and had a history of alcohol and violence. Some believed he could have been capable of the murders. He passed away during the COVID-19 pandemic, so his involvement can no longer be clarified.
Odinism
Before diving into this, a brief definition: Odinism (also called Ásatrú or Heathenry) is a modern revival of pre-Christian Norse and Germanic pagan beliefs, centered around gods like Odin, Thor, and Freyja.
Key Attributes:
- Gods & Myths: Norse gods, Nine Worlds, Yggdrasil, Valhalla
- Rituals: Runes, symbols, offerings, ceremonies tied to nature
- Symbols: Runes, Valknut, Thor’s hammer (Mjölnir), sun wheels
- Values: Honor, loyalty, courage, ancestry
- Modern Variations: Some practice peacefully, others use symbols for extremist purposes
This theory came from Allen’s attorneys, pointing to sticks and branches arranged on the bodies and a rune-like symbol on a tree. The defense argued this could indicate Odinism, but prosecutors stated there is no solid evidence linking the murders to Odinism.
Odinistic killings are usually ideological or ritualistic, not personal. Motives can include:
- Religious rituals or sacrifice
- Ideological extremism
- Symbolic/personal power
- Cult or group pressure
Conspiracy
Questions about police handling have fueled conspiracy theories. Investigators withheld evidence like the full Snapchat video and additional audio. Sketches shifted over time, causing confusion. Some argue poor resource management led to lost tips and delayed FBI involvement. Limited transparency fueled theories that key details were hidden.
