Kedi Cabin Murder
The remaining night in Cabin 28

In April 1981, Sousaf, son John, and friend Dana were found murdered in Cabin 28 in Kedi, a small railway resort in the Sierra Mountains of California. Twelve-year-old Tina disappeared.

From the conclusion of this record to
At least one person around the family was included and it is most likely that there was an accomplice who helped the movement. However, the statements and items recovered decades later are not at the level of concluding that a specific person is the culprit due to the weak context.

Prologue: Recorded Night

After the night deepens, the data was spread on the desk. The first thing that caught my eye was not the answer, but the imbalance. Some scenes were as clear as photographs and some time zones were empty as a whole. People try to capture one clear scene and explain the whole thing, but I marked the empty section first. Mysteries arise because there are many clues, but they also arise because the distance between clues is too far.

The children in the other room of the house survived. Some of Tina's remains were identified in 1984 near Camp Aitin in the distance. The initial investigation was criticized for not sufficiently linking potential sightings with physical evidence, and new items such as hammers were again noted in a later review.

I deliberately read the famous hypothesis at the end. First of all, when we encounter the conclusion, it seems that all objects and symbols exist for that conclusion. Therefore, the timetable, place, object, and original text were organized first, and the witness and interpretation were placed in different compartments. The novel-like atmosphere was drawn from the cold texture of the actual record, not from a made-up secret.

The number of perpetrators, whether Tina was alive when she left the scene, the path of the harmful movement, and the substance of the initial suspect have not been determined.

Caution trap
'Unexplained' is not the same as 'supernatural', 'a huge conspiracy', and 'only this hypothesis is possible'. I didn't count the blanks as evidence.

Scene Reconstruction: Finally, the place of the certain point

was changed to the actual movement, not the stage in your head. We divided the starting point, the last check point, and the location where the item was found and calculated the minimum time required in between. When the dramatic description of later generations was removed, small and specific elements such as sound and lighting, doors and roads, paper and ink, and the spacing of symbols came forward.

The person's mind was not fixed and the action was written first. The same behavior can be caused by fear, planning, error, and fatigue. If it is a code, the same symbol can be a sound, a word, a separator, and a meaningless sign. After writing down all possible roles, he erased the roles that conflict with other records one by one.

Clue 1. Three people were found murdered in Cabin, 28 Kedi on April 12, 1981.

I split this sentence into three pieces first. It indicated who first checked, how close the confirmation was to the incident, and where the later interpretation was attached. Old events and codes turn into clearer stories than the original while being repeatedly cited. But clarity is not the same thing as accuracy. In my notes, I separated the direct record, the traces left by the object, and the reasoning of later generations into different colors.

This clue was then matched with the record, "Young Tina Sharp disappeared from the scene and some remains were found in 1984." It is not a good hypothesis if one hypothesis explains only the first sentence and avoids the second sentence. In particular, if you fail to pass the question, "What sound was transmitted between the room and the living room with children?" the attractive explanation also lowered the score. I've seen clues that make the conclusion uncomfortable longer than clues that make the conclusion cool.

If you look at the clues this way, the case seems a little less dramatic. Instead, there is a boundary between how far it is clear and where it is imagined. That boundary is necessary to correct reasoning when new data are released. The most dangerous moment in the unwritten record is not when you make a false hypothesis, but when you turn the hypothesis into a sentence of fact.

Clue 2. Young Tina Sharp disappeared from the scene and some remains were found in 1984.

Put three hypotheses on the same scale The

hypothesis was not evaluated as a cool sentence. The number of clues to be explained, the number of newly requested assumptions, and the degree to which they endure the opposite evidence were written, respectively. Even if one clue is fully explained, it is not a good hypothesis if the other records have to be discarded.

Hypothesis A. A person close to the family committed a crime with an accomplice on the grounds of conflict.

This explanation has the advantage of accepting "three people were found murdered in Cabin No. 28 of Kedi on April 12, 1981" as a relatively small family. I assumed that this hypothesis was correct and walked time and space all over again. Each time people, objects, and symbols moved to the next location, they wrote down the actions and times they needed. There must have been a hidden assumption at the point where the sentence was cut off.

The biggest weakness is that it does not fully explain "the children in the other rooms in the house survived." If you keep adding accomplices, coincidences, and lost things to keep the hypothesis alive, you can explain anything. However, such an explanation does not predict new clues. I only scored when two independent records pointed in the same direction, and I scored every time I called in a new exception.

117100118

So, whether or not to adopt this hypothesis as a conclusion was judged not by atmosphere but by cost. The number of clues to be explained, the number of newly requested households, and the degree to which they endure evidence against them are listed in the same table. Novel scenes were used to show the texture of facts, but not as evidence to fill in the blanks.

119101120

Hypothesis B. One main culprit dominated the site and another person helped to move and conceal.

121102122

This explanation has the advantage of accepting "Young Tina Sharp disappeared from the scene and some of the remains were found in 1984" as a relatively small assumption. I assumed that this hypothesis was correct and walked time and space all over again. Each time people, objects, and symbols moved to the next location, they wrote down the actions and times they needed. There must have been a hidden assumption at the point where the sentence was cut off.

123103124

The biggest weakness was that "the crime was a way of controlling multiple victims and taking considerable noise.It is not enough to explain " If you keep adding accomplices, coincidences, and lost things to keep the hypothesis alive, you can explain anything. However, such an explanation does not predict new clues. I only scored when two independent records pointed in the same direction, and I scored every time I called in a new exception.

125104126

So, whether or not to adopt this hypothesis as a conclusion was judged not by atmosphere but by cost. The number of clues to be explained, the number of newly requested households, and the degree to which they endure evidence against them are listed in the same table. Novel scenes were used to show the texture of facts, but not as evidence to fill in the blanks.

127105128

Hypothesis C. From the beginning, unexpected witnesses were added to the crime targeting a specific victim.

129106130

This explanation has the advantage of accepting "children in different rooms in the house survived" as a relatively small assumption. I assumed that this hypothesis was correct and walked time and space all over again. Each time people, objects, and symbols moved to the next location, they wrote down the actions and times they needed. There must have been a hidden assumption at the point where the sentence was cut off.

131107132

The biggest weakness is that it does not fully explain "old testimony and items were reviewed again in later re-investigation but did not lead to prosecution." If you keep adding accomplices, coincidences, and lost things to keep the hypothesis alive, you can explain anything. However, such an explanation does not predict new clues.

Conclusions I abandoned

137111138

When I started the investigation, I was also drawn to the most famous explanation. It organized the case into one sentence and gave intention to everything. However, in contrast to the original record, each blank required a new coincidence. I erased the conclusion then and started again. Good reasoning is not about adding anything, but about removing unnecessary assumptions.

139112140

I asked 'who could have stayed in the house naturally' before the brutal scene description. If the three victims were controlled and Tina was moved past the room with children, it would be more advantageous for someone who knows the trust of the family or the path of life than an unfamiliar intruder.

141113142

In particular, the details repeated on later articles and the Internet were separated from the source. Just because the same sentence appears in multiple places does not mean that there are multiple independent sources. We first checked the possibility that one error was duplicated. After this process, the case became less colorful, but the weight of the remaining clues increased.

Anti-evidence: Sentence to destroy my reasoning

145116146

The investigation ends quickly if I gather data that upholds my conclusion. So I put the three most uncomfortable questions next to the conclusion.

147117148

• What sound was transmitted between the room with children and the living room?
150119151
• Why did Tina take her from the scene?
152120153
• Was there any time with the vehicle that was able to move the remains to Camp Aitin?

155122156

These questions are not decorative. It is a switch that will change its conclusion when new data comes in. The ranking of the hypotheses changes immediately when directly linked information, such as the sighting source, preserved physical evidence, comparative samples from the same author, and independent dating. On the contrary, when the word "likely" increased, the ranking did not change.

Final Reasoning: I Reached

159125160

Judgment
At least one person around the family was included and it is most likely that there was an accomplice who helped the movement. However, the statements and items recovered decades later are not at the level of concluding that a specific person is the culprit due to the weak context.

161126162

This conclusion is not a complete final judgment. The direction calls for the fewest assumptions in the currently disclosed records and explains the most clues at the same time. It is also clear that what comes out changes the conclusion. Reliable original records, verifiable legal science data, and independent evidence directly linking people and objects are needed.

163127164

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. It's about finding out what you can throw away among the possible explanations.

Re-expanding the data on the desk, this time covering the conclusion. "Three people were found murdered in Cabin 28 Keddy on 12 April 1981," he continued in a line of place and time. Unconfirmed sections were not filled by imagination but marked with blank squares. The larger the square, the lower the reliability of the hypothesis to pass through the section.

On top of it, I posted an explanation, "A person close to the family committed the crime with an accomplice for conflict reasons." At first, everything seemed right, but when I substituted the question, "What sound was transmitted between the room and the living room with the children?" a weak connection was revealed. Hypothesis has to endure the question. If you keep making new coincidences to avoid questions, you will create, not reasoning, from that moment on.
