Chapter 3 2. The magical "Bone Shrinking Skill" and "Fingerprint"

It turned out that on the eve of his return to China, he drank farewell to several Chinese colleagues at home.After the farewell, everyone took a group photo.Not only can you see a Persian rug in this group photo, but you can also see a Scottish tea set! With photos as evidence, German experts quickly listed a reliable list of stolen items. Now, it's the turn of the police to sit in the wax. Lao Hou was the first group of police officers to arrive at the scene, the sub-team leader, and he can still recall the details of the case to this day. The German expert lived in the third row of buildings southwest of the main road facing the university gate. The crime occurred on the third floor of the six-story building. The inner and outer rooms were basically evacuated. Suspicious traces of value.

The case happened in the unit building, which made Lao Hou very upset. A friend who is a policeman once told me a joke, saying that some film and television dramas are not realistic enough.As long as the phone ringing to report the crime on the TV, the police will be "as crazy as they have been beaten with chicken blood."In fact, the real police are very annoying to the report call, and wish they would never hear it for the rest of their lives.However, if that happens, the police will also face the threat of losing their jobs.Therefore, we can only pray that the place where the crime occurred will be better and that the case will be solved better.

Where is the case easy to solve?It is best to be a traditional residential house, where the neighbors are almost transparent, and it is easy to get information about whether there have been strangers, whether their life is good or not, if you can find one or two people who like to talk about the owner, Li’s family, "Eight wives", then they should be called "case-solving treasures". The apartment buildings where German experts live do not have such good conditions. Most of the residents in the apartment buildings have a cold relationship and seldom communicate with each other. This is true no matter in China or abroad.Japanese porn star Ai Iijima died in the apartment building, and no one knew about it for many days.

Especially in the university, the neighbors are all intellectuals, and they tend to be self-sufficient, which annoys the police uncle very much. Asking the neighbors to find out the situation was as expected, but they returned in vain. Most of the neighbors only knew that this family was a foreign expert, and they didn't even know which country this person was from. Since the doors and windows were in good condition, the direction of detection once pointed to the insider thief, but all the suspects who might be the insider thief soon proved to have no time to commit the crime. The puzzled old Hou walked out of the building door, looked back in a mysterious way, and suddenly realized something.

He asked the security officer who accompanied him: "Can I find out, has anyone seen a thin man around here recently?" "A very thin person?" The security staff who accompanied him were stunned: "How thin is it?" Before Lao Hou could answer, a "professor" suddenly spoke up: "Slim man? Yes, there is a guy who looks like a bamboo pole in an alley. Arrived." "Oh? How long have you not seen him?" "33 days." A month ago, it happened to be the time the investigators deduced that the crime was committed! The "professor" was immediately invited to the office to talk about the thin man he had seen.

The question is, how did this "professor" remember so clearly and accurately judge that the thin man disappeared 33 days ago?More than that, the old man could even describe the skinny man's thick ankle bones and his upper body being longer than his lower body in very detailed features. But he couldn't remember the skinny man's appearance at all! If you ask Lao Hou what he thinks of intellectuals, especially "professors", he must show great respect and wish his son could become a "professor". Hey, comparing a "professor" to a son, what kind of respect is this?

This is not surprising at all. Laohou's education level is limited, and he reckons that his chances of becoming a "professor" are not many, but he sincerely respects learned people and hopes that his son will become a "professor" in the future after studying more. Isn't this a very normal ideal? When it was hot to go abroad, brothers who could not get a visa or a green card often gritted their teeth and decided to have an American or French son. From then on, they no longer had to look at the face of the visa officer. Lao Hou is quite similar. However, if you want to feel Lao Hou’s private thoughts, I’m afraid there are some complaints besides respect—this first-class "professor" is probably a guy with a high IQ and a low EQ, or why even the neighbor next door is a man? Can't tell if it's a woman?If it is very easy to start a civil war in the "Professor"'s house, just ask his mother-in-law's birthday in front of the "Professor"'s wife, or hem and haw, or talk nonsense. opened.

However, after all, such characters are highly intelligent and curious. In Laohou's words, they are a bit like big children. clues.For example, the thin man mentioned by Laohou, no one noticed, but this "professor" remembered it, and was able to explain the various characteristics of the thin man so clearly. After the questioning, Lao Hou said that this person is very suspicious, "Professor", you'd better be at home anytime these days, we still need to ask you to identify him. The "professor" shook his head, saying that it was unlikely, I wanted to work and go on a business trip.

"Going on a business trip? Where are you going?" "Sichuan and Mianyang have a breeding base for fine-bred pigs with lean meat, and Ala has a project there..." I wrote down the phone number of the training base, and after the "professor" went out for a while, Laohou and the others suddenly realized, and laughed like crazy.Needless to say the reason. After laughing, someone asked the captain: "How did you think there was a skinny man in this case?" Lao Hou said that I also had a whim, and we have to collect evidence later.He dragged everyone to the outside of the dormitory building, pointed to the window of the toilet in the apartment of the German expert, and everyone suddenly understood what he was thinking.

All the doors and windows of the German expert apartment are locked, except for the vent above the toilet, the lid is not closed, probably to keep the air in the apartment fresh when no one is around.This vent is square and measures only 30 cm on a side.From downstairs, the opening and closing of this vent can be clearly seen.Investigators can see it, and thieves can certainly see it too. 30 centimeters, that is, the width of a half disc, normal people would never have thought that this would be a place where thieves could come in and out, but Lao Hou thought of it. Because he had read the case files of the old thieves before liberation, and one of the "snitch" confessions mentioned that some skilled habitual thieves were able to deform their bodies and steal into houses through very small windows.This kind of thing is the so-called "bone shrinking skill" in the legend.

In fact, bones cannot shrink, and bone shrinking skills are not mysterious. It is just to know how to stretch ligaments and muscles to change your body shape. In December 2007, Phoenix Satellite TV had a report about the first exchange between the Chinese and Indian militaries after years of estrangement: the Chinese officers and soldiers participating in the exchange performed fierce events such as breaking a monument with a single palm and breaking bricks above their heads. , Shocked everyone. Not to be outdone, the Indian army immediately performed stunts: Indian soldiers performed various shapes such as lotus flowers, railroad tracks, and temples on poles, as well as difficult fire-breathing, which dazzled people. After seeing this report and pictures of the Indian Army’s performance, a grassroots commander of our army was dizzy and said to Sa in private: “I’m convinced, if I encounter such a master in hand-to-hand combat, I don’t know where to start. Start..." Those who surrender without fighting, are Indian soldiers? Regardless of the issue of war, from the perspective of scouts, the continued practice of this Indian soldier is basically the category of bone shrinking skills.However, the bone shrinking skill also has limitations, that is, some things cannot be shrunk.For example, the head, there are those who can make the head smaller. The Incas in Peru are said to have this ability, but they can only change the dead but not the living.This case can only be done by living people, so there is no need to consider this technique. The limit of bone shrinking skill is that as long as the head can pass, people can pass. The 30 cm square ventilation hole, the head can pass through, and people, logically speaking, must also pass through.However, the person doing this case must not be a fat man.If you ask Yingda to do this, no matter how good his kung fu is. Cui Yongyuan... Well, it's about the same as going through the window of CCTV.Forget it, let's not pass through the sieve one by one, Xiao Cui can get in by walking through the door and telling the truth, why go through the window? Thieves with bone shrinking skills are relatively rare, but they are not without them. Lao Hou has always "extravagantly hoped" that he can run into one.Therefore, Lao Hou asked everyone if anyone had seen a thin man. Some people were still wondering: Old Hou, even if the thief could get in, how could he get the TV, carpet, and washing machine out of such a small window?After finishing speaking, I gave myself a big mouth: won't people open the door when they go in?Still need to drill from here?This is a question of IQ. Speculation is speculation, what is needed to solve the case is evidence. Where is the evidence?Lao Hou walked downstairs calmly for a while, and finally turned around and called a trainee investigator: "Go, get the silver powder and brush." Silver powder and a brush are used to take fingerprints. Captain Hou prepared these two things. Where do you want to take fingerprints? After reporting the crime, the fingerprints in the house have been checked once, and the result of that time proved that: apart from the German experts and friends who had been there, the investigators only found the fingerprints of a male stranger in the house, and there were a lot of them. It was the fingerprints of this stranger that made the investigators think of outside thieves, because it is easy to know who can enter and exit this apartment, and it is unlikely that someone will go in and walk half the night, leaving a lot of people behind. Fingerprints, something that German experts don't know yet - the peddler who sells garlic mortar must not have this ability. The scouts judged that the person who left fingerprints was probably the suspect. Now, this judgment has to be discounted: first, modern thieves are also modernized, and they all know the power of fingerprints, and burglars often wear latex gloves.This kind of behavior is very embarrassing for the police. It is not easy for Laohou and the others to find fingerprints full of houses. However, they can’t arrest all latex gloves sellers in China because of this; second, there are many foreigners who come to China. He has become more and more unruly, God knows who he will bring back, what kind of special orientation he will have.Just because the fingerprints left are not of the opposite sex, it is not enough to determine that the person who came was a thief rather than something ambiguous in it.You can't ask about this kind of thing. If someone says "privacy has nothing to do with the case", it will not be easy for you. Fortunately, the situation was not as complicated as it is now. But this conclusion made everyone a little surprised: it means that the whole moving operation may be done by one person. If one person can move people's house without even wine bottles left, is this master a strong man? Lao Hou didn't check the inside of the house this time, what he cared about was how the thief got to the third floor. Old Hou Chong's trainee girl pointed to the drainage pipe outside the apartment building: "Go, you climb up and look for it." Old Hou doesn't do things like take fingerprints, that's for trainee scouts. The official level crushes people to death.When Lao Hou gave an order, they had to climb up and check centimeter by centimeter under the sun. But don't think that Lao Hou is easy. If there is a murder case, there will be a carrion autopsy. Lao Hou will not even be able to wear a mask for the autopsy with the forensic doctor.This was called a different division of labor in the revolution at the time, but now it is called life-suffering and we cannot blame the society... For this old Hou, he joked that the police are a vulnerable group in society, and everyone has their own opinions on whether they recognize it or not. The painstaking efforts paid off, and the little policeman went up and worked hard, and finally came to a conclusion: there were also fingerprints on the drain pipe, which matched the fingerprints of the strangers in the house! Now that the suspect has been found, Lao Hou smiled: This time, you don't have to worry about eating other people's braised pork for nothing. The fingerprints found here show that Laohou's idea is right. Someone has indeed climbed up the drainpipe. Everyone will ask: Can the fingerprints on the drainpipe a month ago, exposed to the wind and sun, still be preserved? What's so strange about this is that fingerprints leave not only indentations, but also residues such as fat. Under extreme conditions, archaeologists have even collected fingerprints thousands of years ago.Of course, it also depends on the carrier and the environment, such as the door handle of a building, hundreds of people come in and out every day, pull and pull, and fingerprinting is basically meaningless. Laohou always pays attention to fingerprints when solving cases. There is an example. One day, Lao Hou was on sick leave, and was called to a certain hotel by a phone call: His subordinates have encountered troubles, and they asked Captain Hou to come forward to help make peace. what happened?The police still care about making peace? It turned out that there was a theft in the local area, and some cash put in an envelope by a certain diplomat was stolen. The police officer who handled the case quickly came to a judgment based on the records of entering and leaving the room.It should be said that the professional level of this police officer is still good, but this person's style is a bit simple and rude, and he used some methods against the suspect, but he did not get any evidence. Unfortunately, the suspect firstly compares himself with hob-blade meat, and his methods are ineffective; secondly, he has some special family and social relationships, and he persisted even though the case was not settled.After the dispute between the two parties, I thought that Lao Hou had worked in the Foreign Affairs Office for a long time and had rich social connections, so I asked him to help mediate. Lao Hou came to the restaurant and quickly solved the problem. He didn't do mediation, because looking at this case, Lao Hou felt that there was still work to be done.Lao Hou pointed to the envelope where the diplomat put the money, and told the scouts to do fingerprint identification.The scout didn't move the place, and said, Lord Hou, our team leader has already checked it, and there are no fingerprints on it, probably the suspect wiped it off.Lao Hou didn't raise his eyes, and said that he would use enhanced inspection methods and test again. As a result, several fuzzy fingerprints were found. Although the one on the inside of the envelope was fuzzy, it could still be compared. It was in line with the suspect.After solving the main contradiction of who is the thief, the matter of resorting to means is a secondary contradiction, so it is naturally easy to solve. Afterwards, someone said that Lao Houshen could guess that the envelope had been wiped and there were fingerprints on it.Lao Hou himself didn't think so. He said that the envelope was a special envelope for a certain European government. It was of good quality and strong absorption. Soaking in sweat will leave deeper marks.With these two points, even if the envelope is wiped after committing the crime, there may still be residual fingerprints. "It's just a logical problem plus an empirical problem." Lao Hou said.
