Everyone was stunned when they heard what those female students said, and the pen fairy was not a new statement at that time. With the rise of the Internet, the forum on the Internet, especially the ghost talk section on a forum, has long spread the pen fairy. Since I have encountered many superstitious cases, I have been exposed to a lot of these contents.

The term "pen immortal" did not come into being in modern times, and it is recorded in many ancient books, and it evolved from one of the oldest witchcraft in history, and was first called fu 乩 (jī), which is a form of divination. Fu Ping generally refers to the use of a horizontal stick and a pen, two fingers against the horizontal stick, there is a sand table below, the pen draws the lines in the sand table, the main servant reads the "Book of Heaven".

When the school leaders heard this, they angrily scolded the female students, saying that they were ridiculous. These leaders have been in administrative positions for many years, and their main responsibility is to manage the affairs of the police academy, and they do not have a special understanding of the investigation, and the only help they can provide for cases is to mobilize police academy experts and assist the police in handling cases.

They didn't know much about the traces and physical evidence extracted from the scene, so naturally they didn't think about the pen and the blank paper on the table. Many female students said that they either intentionally or overheard the people in the dormitory talking about playing this kind of game, and then contacted pen and paper, I am afraid that the three female students really went to play this kind of game.

I interrupted the leader's words and asked a few female students to continue, and the investigation experts and Wen Ning who were present also felt that something was wrong, and they all surrounded them. At the urging of everyone, several female students continued.

The reason for the incident was that a week ago, after the usual physical training was over, it was already night, and the female students went back to the dormitory one after another to take a shower and rest. The female students who were present said that when they passed by the deceased's dormitory, they found it full of screams, and when they walked in, they realized that the four people in the dormitory were reading an old book bought under the overpass.

There are many ways to see ghosts in the book, and among them is the pen fairy. The four people in the deceased's dormitory were horrified to watch, so they let out screams, and many people expressed their incomprehension of their actions, saying that there were no ghosts in this world at all. The four girls in the dormitory were convinced of the contents of the book and said they would give it a try.

The day before leaving school for the holiday, the four girls said they would try it again, and at that time everyone thought they were joking, and this kind of play was completely false, so everyone didn't pay attention to it. But unexpectedly, after they went home, they received a notice from the school and immediately returned to the police academy.

They thought that it might have something to do with the incident, so after discussing it, they decided to provide clues to the police and the police academy. Wen Ning beckoned, and immediately asked people to go to the dead man's dormitory to find the book that could see ghosts. The police have conducted an inquest into the deceased's quarters, but they have focused their main efforts on trace extraction.

As far as I know, there are a lot of textbooks and textbooks for every student at the police academy, and the three deceased and another girl in the dormitory are already in the stage of graduation, and there are even more books, so the police have not investigated them one by one. The people sent by Wen Ning immediately went to look for the book, and Wen Ning also told them to carefully go through each book several times, and if they found other strange books, they would also bring them back.

Wen Ning asked everyone to sit down and continued to ask about the female students present. Everyone said that since the four girls read that kind of book, they all seemed to be different people, they didn't even dare to go out at night, and they also took leave of absence for physical training, and finally went to participate in a few evening training sessions under the pressure of the instructor.

But everyone found that the four girls were absent-minded and often nervous, and even went to the bathroom with four people. For several nights, when everyone was about to fall asleep, they could hear screams coming from the dormitory of the four girls, and at first some people were worried about knocking on the door to investigate, but after discovering that the four girls scared themselves, no one paid attention to them.

A lot of people have complained about keeping them from being too noisy at night, but the screams always sound at midnight.

As soon as the girls said this, I immediately connected to the strange behavior of the four girls that night. If it had been influenced by that book, the suspicious behavior of the four girls would have been explained. After Wen Ning asked, I asked what I wanted to know.

I need to know all the aspects of the deceased so that it is easier to solve the case. I asked about the personalities of the four girls and how they did in school. Everyone said that the four people in the dormitory have similar personalities, treat people very well, and their academic performance is average, because the four girls are all outsiders, so unless they are winter and summer vacations, they do not often go out of the police academy, except for buying daily necessities to go out of school, the rest of the time, they are spent in the police academy.

At the end of the questioning, Wen Ning asked the female students to sign the interrogation transcript and let them all go back. After a while, the door of the appraisal room finally opened, and the appraiser walked out of the appraisal room sweating profusely. Wen Ning hurriedly inquired about the results of the appraisal.

The appraiser gave us a copy of the photocopied appraisal results, and we listened to the appraiser's analysis against the above records. The comparison of the footprints has come out, and the three footprints at the scene are indeed left by the three pairs of shoes at the scene of the crime, and the three pairs of shoes, through DNA comparison, the three pairs of shoes and three sets of clothes have also been confirmed to be the three deceased.

As for the other footprint of Geng Fufu, the owner of the farmhouse, since no sole with the same pattern was found, there is no way to directly confirm that it was left by the fourth girl in the dormitory, but according to the shoes retrieved from the deceased's dormitory, the appraiser presumed that the footprints belonged to the fourth girl through the comparison of the size and width of the shoes.

For the identification of fingerprints, due to the small force area of the pencil, the fingerprints are all overlapped together, and the appraisers have taken great pains to extract and identify multiple overlapping fingerprints. Compared with the fingerprints collected from the girls' dormitory, the appraisers found that all the fingerprints left on the pencils had appeared in the girls' dormitory.

In order to rule out that someone else left fingerprints in the girls' dormitory, the appraisers and the police specially selected several personal belongings in the girls' cabinets for extraction, which are generally only touched by the owner himself. Through exclusion, a total of 40 fingerprints of different fingers were extracted from the girls' dormitory, and the appraisers identified these fingerprints as the lines on the ten fingers of four people.

The conclusion given by the expert is clear, and coupled with the presumption of footprints, it can be basically confirmed that the fourth female student in the dormitory also visited the scene. Wen Ning asked the leader of the police academy if the girl could be contacted, the leader shook his head, saying that the girl did not have a mobile phone, contacted the family, and relatives also said that she did not go home.

Because of the fear that something would happen to the girl, the girl's relatives immediately rushed to City B.

Everyone frowned and pondered, seeing that everyone didn't speak, the leader of the police academy asked me what I thought, Wen Ning glanced at me, pretended to smile, and let me talk about it.

"The fingerprints of the four girls were found on the pencils found at the scene, which indicates that the four girls probably played the game of Fu Ping, that is, the pen fairy, before they died, haven't you thought that this kind of game needs a pen, and the wounds on the three corpses were also pierced by the pen, don't you think it's strange?" I asked.

Wen Ning retorted: "One is a pencil and the other is a fountain pen, Professor Li, your statement is too far-fetched, right?" ”

I shook my head: "It's just my speculation, I think there's a connection between the two." As soon as Wen Ning wanted to refute again, I gaged him with a sentence. Wen Ning believed that piercing the wound with a pen was just an act that the suspect had not carefully considered, but the palms and soles of the deceased's hands and feet were amputated, and the wounds were relatively smooth, so the tool for amputating the limbs should be a relatively sharp knife.

If there is a knife, why did the suspect use a pen to stab the body.

When I asked, everyone shut up. Human skin and muscle tissue are tough, and each corpse has dozens of pen-piercing wounds, and it is absolutely impossible to use one pen to pierce three corpses with hundreds of wounds, because the fountain pen will be damaged.

This requires careful consideration of the murderer's purpose......
