Vilisca Ax Murder
The Unclosed Case of Iowa, 1912
▲ Cover of the incident – Unfolding the records
In June 1912, two adults and six children were found dead in a home in Villiska, Iowa. A trial and confession followed, but no conviction was established.
Villisca's mystery remained not because there were no suspects, but because there was a lack of reliable evidence to pin a suspect on the scene.
Prologue: The night that broke records
When I laid out the case data on my desk, the first thing I noticed was not the correct answer but an imbalance. Some scenes were overly clear, and some time periods were completely blank. People try to explain the entire incident by focusing on one clear scene, but I instead marked the blank section first. Mysteries can arise because there are many clues, but they can also arise because the distance between clues is too great.
The victims were six members of the Moore family and two Stillinger sisters who were spending the night. It was found that an ax inside the house was used as the crime weapon.
I did not view this incident as confirming an already known conclusion. The records were arranged chronologically, the movement paths of objects were drawn separately, and sightings and interpretations were indicated in different colors. The most popular explanations were then deliberately reviewed last. Because when you first read a famous hypothesis, all the clues seem to exist for that hypothesis.

Case Files: What I Could Believe

|---|---|---|
| 1 | The crime is believed to have occurred between the night of June 9 and the early morning of the 10th, 1912. | high |

| 3 | Circuit minister George Kelly was indicted and tried twice, but was not found guilty. | middle |
| 4 | Other serial crime theories and local resentment theories have also been suggested, but there has been no official conclusion. | middle |
The route of entry, the motive for the crime, whether there was one or multiple perpetrators, and any connections to similar Midwestern murders remain.
The sentence ‘It is not explained’ is not the same as the sentence ‘It is supernatural’ or ‘Someone intended it’. I didn't use the blank space as evidence.
▲ Timeline – Flow before and after the event
Reconstructing the Scene: Finally, a Certain Point
I changed the location where the incident took place to the actual route rather than the stage in my head. We divided the starting point, final confirmation point, and discovery location and calculated the time needed in between. In the process, several later dramatic depictions were omitted. Instead, the recorded sounds, weather, means of transportation, and locations of objects came to the fore. The novelistic atmosphere arose from the very texture of the facts. There was no need to add unidentified secret passageways or nameless accomplices.
When reconstructing the last scene, I did not determine the character's feelings. The same behavior can be caused by fear, planning, mistake, or fatigue. So, I wrote down the actions first and left the emotions to the extent possible. Thanks to this principle, events became less flashy but more concrete.
Clue 1. The crime is believed to have occurred between the night of June 9 and the early morning of June 10, 1912.
I placed this sentence in the middle of the case record and checked the tense first. It was differentiated from who observed it and when, and whether it was written down on the spot or added from memory later. The older the clues to an unsolved case, the more seamless the story becomes. However, what is needed in an investigation is not smoothness but provenance. The moment I discerned whether this clue was a direct observation, a trace left by an object, or someone's interpretation, the outline of the incident changed.
If we leave out this clue, a one-way conclusion seems very plausible. However, I immediately tried to tackle the following record: “With so many people coming and going from the site, it has become difficult to preserve evidence by modern standards.” If the two do not naturally coexist in the same explanation, the explanation is still just a story. In particular, a hypothesis that does not pass the question, “If there was no contamination at the site, what evidence should have been checked first?” ends up ignoring the rest of the record instead of explaining one clue.
So I created three spaces in my case notes. The first is a confirmed fact, the second is an inference that goes one step further from the facts, and the third is a possibility that cannot be selected without additional evidence. This clue is a mixture of parts that are close to the first space and parts that stay in the second space. I didn't erase that boundary. Leaving boundaries is the only way to modify your reasoning later when new records emerge.

Clue 2. With so many people coming and going from the site, it has become difficult to preserve evidence by modern standards.
I placed this sentence in the middle of the case record and checked the tense first. It was differentiated from who observed it and when, and whether it was written down on the spot or added from memory later.

The moment I discerned whether this clue was a direct observation, a trace left by an object, or someone's interpretation, the outline of the incident changed.
If we leave out this clue, a one-way conclusion seems very plausible. But I immediately tried the next record: “Itinerant minister George Kelly was indicted, tried twice, but not found guilty.” If the two do not naturally coexist in the same explanation, the explanation is still just a story. In particular, a hypothesis that does not pass the question, “Is the repetition of similar crimes a trace of the same criminal or a result of the environment of the time?” ends up ignoring the rest of the record instead of explaining one clue.
So I created three spaces in my case notes. The first is a confirmed fact, the second is an inference that goes one step further from the facts, and the third is a possibility that cannot be selected without additional evidence. This clue is a mixture of parts that are close to the first space and parts that stay in the second space. I didn't erase that boundary.

Clue 3. Circuit pastor George Kelly was indicted and tried twice, but was not found guilty.
I placed this sentence in the middle of the case record and checked the tense first. It was differentiated from who observed it and when, and whether it was written down on the spot or added from memory later. The older the clues to an unsolved case, the more seamless the story becomes. However, what is needed in an investigation is not smoothness but provenance. The moment I discerned whether this clue was a direct observation, a trace left by an object, or someone's interpretation, the outline of the incident changed.
If we leave out this clue, a one-way conclusion seems very plausible. However, I immediately tried to confront it with the next record, “Other serial crime connection theories and local resentment theories have also been suggested, but there has been no official conclusion.” If the two do not naturally coexist in the same explanation, the explanation is still just a story. In particular, a hypothesis that does not pass the question “Which should take precedence when a confession conflicts with physical evidence?” ends up ignoring the rest of the record instead of explaining one clue.
So I created three spaces in my case notes. The first is a confirmed fact, the second is an inference that goes one step further from the facts, and the third is a possibility that cannot be selected without additional evidence. This clue is a mixture of parts that are close to the first space and parts that stay in the second space. I didn't erase that boundary. Leaving boundaries is the only way to modify your reasoning later when new records emerge.

Clue 4. Other serial crime connection theories and local resentment theories have also been suggested, but there is no official conclusion.

If we leave out this clue, a one-way conclusion seems very plausible.

put three hypotheses on the same scale
Hypotheses were not evaluated in fancy sentences. We wrote down the number of explanatory clues, the number of new assumptions required, and the degree to which they can withstand contrary evidence. Even if one clue is completely explained, if the remaining three clues have to be discarded, it is not a good hypothesis.
Hypothesis A. A crime planned by someone who knows the family.
The advantage of this explanation is that it makes relatively few assumptions: “The crime is believed to have occurred between the night of June 9 and the early morning of June 10, 1912.” I first assumed that this hypothesis was true and re-traced the event from beginning to end. Each sentence linked where and what the character saw, what judgment he made, and then moved to the next location. There was always a hidden assumption at the point where the connection was lost.
The biggest weakness is that it does not sufficiently explain “Itinerant pastor George Kelly was indicted and tried twice but was not found guilty.” If you keep adding exceptions to your hypothesis, you can explain anything, but such an explanation predicts nothing. I lowered the score of the hypothesis the moment there were more than two exceptions. Conversely, scores were increased only when two independent clues pointed in the same direction.
In the end, this hypothesis cannot be completely discarded, but it cannot be taken as a conclusion either. If you read the incident like a novel, the blank spaces will be filled in naturally. If you read it like an investigation record, the blank spaces remain. I chose the latter. Even if the blank space left is inconvenient, that inconvenience protects the scope of what the evidence can say.
Hypothesis B. A serial killer who moved across several states committed a crime.
The advantage of this explanation is that it makes relatively few assumptions: “The site is visited by so many people that it has become difficult to preserve evidence by modern standards.” I first assumed that this hypothesis was true and re-traced the event from beginning to end. Each sentence linked where and what the character saw, what judgment he made, and then moved to the next location. There was always a hidden assumption at the point where the connection was lost.
The biggest weakness is that it does not sufficiently explain “Other serial crime connection theories and regional resentment theories have also been suggested, but there has been no official conclusion.” If you keep adding exceptions to your hypothesis, you can explain anything, but such an explanation predicts nothing. I lowered the score of the hypothesis the moment there were more than two exceptions. Conversely, scores were increased only when two independent clues pointed in the same direction.
In the end, this hypothesis cannot be completely discarded, but it cannot be taken as a conclusion either. If you read the incident like a novel, the blank spaces will be filled in naturally. If you read it like an investigation record, the blank spaces remain. I chose the latter. Even if the blank space left is inconvenient, that inconvenience protects the scope of what the evidence can say.
Hypothesis C. Crimes committed due to a combination of regional conflict and personal resentment
The beauty of this explanation is that it makes relatively few assumptions about the proviso that “Itinerant pastor George Kelly was indicted, tried twice, but not found guilty.” I first assumed that this hypothesis was true and re-traced the event from beginning to end. Each sentence linked where and what the character saw, what judgment he made, and then moved to the next location. There was always a hidden assumption at the point where the connection was lost.

▲ Comparison of hypotheses – explanatory power and gaps
Conclusions I threw away
When I began my investigation, I too was drawn to the most popular explanation. It summed up events in one sentence and gave intention to every object. But when the data was collated, the explanation required a new coincidence for every blank space. I erased that conclusion and started again. Good reasoning is less about adding things and more about removing unnecessary assumptions.
Later comparisons may show similarities in the methods of the crime, but they do not prove the same culprit. The contaminated scene and unstable confession are the biggest limitations of the case.
In particular, details repeated in later testimonies and on the Internet were separated from the original records. Just because the same sentence appears in multiple places does not mean there are multiple independent sources. First, we checked the possibility that a single incorrect sentence was duplicated. After going through this process, the size of the case decreased, but the weight of the remaining clues actually increased.
▲ Counterevidence check — the conclusion I discarded
Final Reason: What I arrived at
Villisca's mystery remained not because there were no suspects, but because there was a lack of reliable evidence to pin a suspect on the scene.
This conclusion is not a completely definitive ruling. This is a direction that requires the fewest assumptions and simultaneously explains the most clues within the currently available records. It may be revised as new physical evidence emerges. However, it is also clear that the conclusion may change depending on what comes out. Reliable original records, verifiable forensic data, and independent evidence directly linking objects and people are needed.
I do not write that the case is closed. Instead, write down how far you can close it. That boundary is the result of this investigation. The fun of mystery is not that anything is possible. The goal is to find out which of the possible explanations can be discarded.
▲ Final judgment – explanation that requires the fewest assumptions
Additional Investigation Records 1. Redraw the timeline
At dawn, I opened the case sheet again. This time, the conclusion was obscured and only a record was left: “The crime is believed to have occurred between the night of June 9 and the early morning of June 10, 1912.” Even events you thought you already knew reveal a completely different picture if you erase the conclusion. I lined up the locations and times and wrote down the minimum travel time. The gaps between records were not filled by imagination but were marked with empty squares. As the square grew, the reliability of the hypothesis explaining that section decreased.
Above that, I put the hypothesis that “a crime was planned by someone who knew the family.” At first everything seemed to fall into place. However, when we asked the question, “If there was no contamination at the site, what evidence should have been checked first?”, a weak part of the explanation was revealed. Hypotheses must withstand questioning. If you keep bringing in new characters or coincidences to avoid questions, from that moment on, it becomes creation rather than reasoning. I used my creative sense only for the mood of the sentence and did not place it in the place of facts.
The results I got from this section are neither a definitive name for the culprit nor a complete decipherment. Instead, it became clear which explanations required fewer assumptions and which ones flipped when new discoveries were made. Even if the case cannot be closed, it is possible to narrow the scope of the investigation. This record is intended to leave behind that narrowed boundary.
