My Case Investigation Record 20 <SEG0/> Hinterkaipek Murder
Six victims of a Bavarian farm in 1922
▲ Cover of events — opening records
A family and six maids were killed at a Hinterkaipek farm in Bavaria, Germany. Footprints, lofts and rumors of a criminal staying are famous, but the intensity of the records is different.
Hinterkaipek is a case where a long list of suspects cannot be solved if the evidence chain is short.
Prologue: A Record-Breaking Night
When I unfolded the incident data on the desk, the first thing I noticed was not the correct answer, but the imbalance. Some scenes were too clear, and some times were entirely empty. People try to explain the whole incident by holding on to a clear scene, but I marked the empty section first. Mysteries arise because there are many clues, but sometimes the distance between them is too far.
The victims were found on the farm after being invisible for several days. The crime tool was estimated to be a pick tool on the farm.
I didn't see this event as a work to confirm a known ending. The records were arranged in chronological order, the routes of the objects were drawn separately, and the sightings and interpretations were marked in different colors. The most famous explanation was then deliberately reviewed at the end. Because if you first read a famous hypothesis, all the clues appear to exist for that hypothesis.

Case Files: What I Could Believe
| Number | Verified Records | Current Reliability |
|---|---|---|
| 1 | The crime is estimated to be around March 31, 1922. | High |
| 2 | The possibility was raised that someone stayed after the crime, including traces of livestock being cared for and chimney smoke. | High |
| 3 | The site was contaminated with a large number of visitors and the initial investigation skills were limited. | the middle |
| 4 | Several suspects were investigated, but no conviction was made. | the middle |
The motive of the crime, the order in which the victims were lured to the barn, whether they stayed after the crime, and whether they were the sole offenders remain.
The sentence 'unexplained' is not the same as the sentence 'supernatural' or 'someone intended'. I didn't use the blanks as evidence.
▲ Timeline — Flow before and after events
Reconfiguring Scene: The Last Definite Point
I changed the place where the incident took place to a real route rather than a stage in my head. I divided the starting point, the last check point, and the place of discovery, and calculated the time required in the meantime. Several dramatic descriptions of later generations were missing in the process. Instead, the recorded sound, weather, means of transportation, and the location of objects came forward. The fictional atmosphere arose from the texture of that very fact. There was no need to add an unidentified secret passage or an unnamed accomplice.
When I reconstructed the last scene, I did not make up the character's mind. Fear, planning, error, and fatigue can cause the same behavior. So, I wrote down my actions first and left my emotions only to the extent possible. The events became less colorful but more specific thanks to this principle.
Clue 1. The crime is estimated to be around March 31, 1922.
I placed this sentence in the middle of the case record and checked the tense first. It started from who observed it, when it was written right on the spot, or whether it was added as a later memory. The longer the clues to the unsolved case get, the smoother it becomes. However, what is needed in the investigation is not the smoothness but the source. The outline of the case changed as soon as the clue was distinguished whether it was a direct observation, a trace left by an object, or someone's interpretation.
If only this clue is separated, a conclusion in one direction seems very plausible. However, I immediately confronted the next record, "The possibility that someone stayed after the crime, such as traces of the caring of the livestock and chimney smoke, was raised." If the two do not naturally coexist in the same explanation, the explanation is still only a story. The hypothesis that fails to pass the question of "How strongly will the traces of livestock management after the crime support the criminal's stay?" turns away from the rest of the records instead of explaining one clue.
So I made three compartments in my case notes. The first is confirmed facts, the second is reasoning that has only taken one step from facts, and the third is the possibility that you cannot choose without additional evidence. This clue is a mixture of the parts that are close to the first compartment and the parts that stay in the second compartment. I did not erase that boundary. Because leaving boundaries is the only way to correct reasoning when new records emerge later.
▲ Key Clue 1 — Traces left by records
Clue 2. The possibility that someone stayed after the crime, such as traces of the livestock being cared for and chimney smoke, was raised.
I placed this sentence in the middle of the case record and checked the tense first. It started from who observed it, when it was written right on the spot, or whether it was added as a later memory. The longer the clues to the unsolved case get, the smoother it becomes. However, what is needed in the investigation is not the smoothness but the source. The outline of the case changed as soon as the clue was distinguished whether it was a direct observation, a trace left by an object, or someone's interpretation.
If only this clue is separated, the conclusion in one direction seems very plausible. However, I immediately confronted the next record, "The scene was contaminated with a large number of visitors and the initial investigation technology was limited." If the two cannot naturally coexist in the same explanation, the explanation is still only a story. In particular, the hypothesis that does not pass the question of "Why did the family move to the barn one by one?" turns away from the rest of the records instead of explaining one clue.
So I made three compartments in my case notes. The first is confirmed facts, the second is reasoning that has only taken one step from facts, and the third is the possibility that you cannot choose without additional evidence. This clue is a mixture of the parts that are close to the first compartment and the parts that stay in the second compartment. I did not erase that boundary. Because leaving boundaries is the only way to correct reasoning when new records emerge later.
▲ Key clue 2 — An mismatched piece
Clue 3. The scene was contaminated with a large number of visitors and the initial investigation skills were limited.
I placed this sentence in the middle of the case record and checked the tense first. It started from who observed it, when it was written right on the spot, or whether it was added as a later memory. The longer the clues to the unsolved case get, the smoother it becomes. However, what is needed in the investigation is not the smoothness but the source. The outline of the case changed as soon as the clue was distinguished whether it was a direct observation, a trace left by an object, or someone's interpretation.
If we separate this clue, a conclusion in one direction seems very plausible. However, I immediately confronted the next record, "Multiple suspects have been investigated but no conviction has been made." If the two do not naturally coexist in the same explanation, the explanation is still only a story. In particular, a hypothesis that fails to pass the question of "How is local resentment compatible with the traces of theft?" turns a blind eye to the rest of the records instead of explaining one clue.
So I made three compartments in my case notes. The first is confirmed facts, the second is reasoning that has only taken one step from facts, and the third is the possibility that you cannot choose without additional evidence. This clue is a mixture of the parts that are close to the first compartment and the parts that stay in the second compartment. I did not erase that boundary. Because leaving boundaries is the only way to correct reasoning when new records emerge later.
▲ Key clue 3 — Evidence that shakes the hypothesis
Clue 4. Several suspects have been investigated but no conviction has been made.
I placed this sentence in the middle of the case record and checked the tense first. It started from who observed it, when it was written right on the spot, or whether it was added as a later memory. The longer the clues to the unsolved case get, the smoother it becomes. However, what is needed in the investigation is not the smoothness but the source. The outline of the case changed as soon as the clue was distinguished whether it was a direct observation, a trace left by an object, or someone's interpretation.
If this clue is separated, the conclusion in one direction seems very plausible. However, I immediately confronted the next record, "The crime is presumed to be around March 31, 1922." If the two do not naturally coexist in the same explanation, the explanation is still only a story. In particular, the hypothesis that fails to pass the question of "How strongly will the livestock management trace after the crime support the criminal's stay?" turns a blind eye to the rest of the records instead of explaining one clue.
So I made three compartments in my case notes. The first is confirmed facts, the second is reasoning that has only taken one step from facts, and the third is the possibility that you cannot choose without additional evidence. This clue is a mixture of the parts that are close to the first compartment and the parts that stay in the second compartment. I did not erase that boundary. Because leaving boundaries is the only way to correct reasoning when new records emerge later.
Putting the three hypotheses on the same scale, the
hypothesis did not evaluate them in a nice sentence. The number of clues to be explained, the number of newly requested assumptions, and the degree to which they can withstand opposite evidence were written down, respectively. A complete explanation of one clue is not a good hypothesis if the other three are discarded.
Hypothesis A. Crime of an acquaintance with family relationships and grudges
The advantage of this explanation is that it accepts the clue that "the crime is presumed to be around March 31, 1922" as a relatively small assumption. I first assumed that this hypothesis was true and re-staged the case from start to finish. I connected where the character saw what he saw, what he made, and what he moved to the next place one sentence by one. At the point of disconnection, there must have been a hidden assumption.
The biggest weakness is that it does not fully explain "the scene was contaminated with multiple visitors and the initial investigation skills were limited." Anything can be explained by continuing to add exceptions to keep the hypothesis alive, but such an explanation does not predict anything. I lowered the score of the hypothesis the moment the two exceptions were exceeded. Conversely, I raised the score only when two independent clues pointed in the same direction.
In the end, this hypothesis cannot be completely discarded, but it cannot be concluded as it is. If you read an event like a novel, the blanks will naturally fill in. If you read it like an investigative record, the blanks will remain the same. I chose the latter. Even if the blanks left are uncomfortable, the inconvenience protects the extent to which the evidence can speak.
Hypothesis B. Explanation that the invasion for the purpose of theft spread to murder
The advantage of this explanation is that it accepts the clue that "the possibility that someone stayed after the crime, such as the trace of the livestock's care and the smoke of the chimney, was raised." I first assumed this hypothesis to be true and re-stalled the time of the event from beginning to end. I connected where and what the character saw, what judgment he made, and moved to the next place one sentence at a time. At the point of disconnection, there must have been a hidden assumption.
The biggest weakness is that it does not fully explain "multiple suspects have been investigated but no conviction has been made." If we keep adding exceptions to keep the hypothesis, we can explain anything, but such an explanation does not predict anything. I lowered the score of the hypothesis the moment the two exceptions were exceeded. Conversely, I raised the score only when two independent clues pointed in the same direction.
In the end, this hypothesis cannot be completely discarded, but it cannot be concluded as it is. If you read an event like a novel, the blanks will naturally fill in. If you read it like an investigative record, the blanks will remain the same. I chose the latter. Even if the blanks left are uncomfortable, the inconvenience protects the extent to which the evidence can speak.
Hypothesis C. Explanation that a mobile criminal chose a farmhouse
The advantage of this explanation is that it accepts the clue as a relatively small assumption, "The scene was contaminated with multiple visitors and the initial investigation skills were limited." I first assumed that this hypothesis was true and re-staged the case from start to finish. I connected where the character saw what he saw, what he made, and what he moved to the next place one sentence by one. At the point of disconnection, there must have been a hidden assumption.
The biggest weakness is that it does not fully explain "the offense is presumed to be around March 31, 1922. If you keep adding exceptions to keep the hypothesis, you can explain anything, but such an explanation does not predict anything. I lowered the score of the hypothesis the moment the two exceptions were exceeded. Conversely, the score was raised only when two independent clues pointed in the same direction.

If you read it like an investigative record, the blanks will remain the same. I chose the latter. Even if the blanks left are uncomfortable, the inconvenience protects the extent to which the evidence can speak.
▲ Hypothesis Comparison — Explanatory power and gaps
The conclusions I abandoned
I was also drawn to the most famous explanation at the beginning of the investigation. It organized the case in one sentence and gave everything intention. However, when the data were compared, the explanation required a new coincidence for each blank. Then I erased the conclusion and started again. Good reasoning was more about removing unnecessary assumptions than adding anything.
The claim that the criminal stayed on the farm explains some circumstances, but not all details are identified equally with contemporary records. There is not enough evidence to connect the suspect with the tool.
In particular, the details repeated on the Internet and later testimonies were separated from the original record. Just because the same sentence appears in multiple places does not mean that there are multiple independent sources. The possibility that one wrong sentence was duplicated was first confirmed. The size of the case decreased after this process, but the weight of the remaining clues increased.
▲ Counterfeit Checks — The Conclusion I Abandoned
Final Reason: The Results I Reached
Hinterkaipek is a case where a long list of suspects cannot be solved if the evidence chain is short.
This conclusion is not a complete final decision. It is a direction that requires the least assumptions in the currently disclosed records and explains the most clues at the same time. It can be corrected when new evidence comes out. However, it is also clear that the conclusion changes when it comes out. Reliable original records, verifiable legal and scientific data, and independent evidence that directly connects objects and people are needed.
I don't write that I closed the case. Instead, write how far you can close it. That boundary is the result of this investigation. The fun of the mystery is not that anything is possible. It is in finding out what can be thrown away among the possible explanations.
▲ Final Judgment — Description that requires the least assumption
Additional Investigation Records 1. Redraw the Timeline
Reopen the event table at dawn. This time, he only covered up the conclusion and left a record saying, "The crime is presumed to be around March 31, 1922. Even incidents that I thought I already knew will take a completely different shape if I erase the conclusion. I connected the place and time in a line and wrote the minimum time required for movement. The gap between the records was marked with an empty square without filling in imagination. The larger the square, the lower the reliability of the hypothesis explaining the section.
On top of it, I posted the hypothesis, "The crime of an acquaintance with family relationships and desires." At first, everything seemed to fit. However, when the question, "How strongly will the traces of livestock management after the crime support the criminal's stay?" was substituted, the weak part of the explanation was revealed. The hypothesis must endure the question. If you keep calling new people or coincidences to avoid questions, from that moment on, it becomes creation, not reasoning. I used the sense of creation only in the atmosphere of the sentence and did not put it in the place of fact.
The result I got from this section is not the name of the criminal or the complete decryption. Instead, it became clear which explanations required fewer assumptions and what would be reversed if new findings were made. Even if the case is not completed, it is possible to narrow the scope of the investigation. This record is intended to leave that narrow boundary.
