Chapter 9 4. "Doubtful Formation" makes old and little gods helpless

In the middle, Zhang Liangji and other commanders thought of a person—Ma Yulin, the founder of Chinese footwork tracking.Ma Yulin is a pioneer in the scientific detection of Chinese public security circles.Because he created the practical footprint analysis technology, he can scientifically judge the suspect's age, height, weight, gender, etc. through the footprints, and has solved many major cases based on this.Insiders in the public security circle gave him the nickname "Horse Immortal". A friend provided a small case of Immortal Ma: “One year there was a cable theft case in the coal mine of my hometown, and the public security organs invited Immortal Ma. After he came to the coal mine, he first looked at the scene of the crime, and then he looked at the footprints of all the workers in the factory where the cable was thrown. After reading it, he asked one of them to cut the cable in front of him. After cutting the cable, Mr. Ma stared at his eyes and said that you cut it with your left hand, so the man cut it with his left hand. After cutting the cable, Mr. Ma took a look at the traces of the cable and decided that it was him. During the investigation of this case, Mr. Ma Not only looked at the footprints, but also observed the traces of the criminal cutting the cables, and he deduced that the criminal committed the crime with his left hand."

Zhang Liangji believes that although "Scud" runs fast, it is not a bird after all.As long as he lands, there must be footprints.With footprints, Immortal Ma has a chance to strike.When the "Scud" case was solved, Ma Shenxian was old, and the job of tracking footprints was entrusted to Sun Zhongsheng, a disciple of Ma Shenxian.Sun Zhongsheng has won the true biography of Immortal Ma, and has repeatedly solved strange cases. The cases and analysis methods he told the scouts were eye-opening.Sun Zhongsheng's live performance is even more exciting. For example, when soldiers, farmers, and drivers land on the ground, the center of gravity of the footprints is obviously different.Therefore, let the scouts collect footprints at will, and the depth of different parts of Sun Cong's footprints can actually determine the suspect's occupation.This set of skills made the scouts very admired, and they called Sun Zhongsheng a "little fairy".The arrival of Sun Zhongsheng opened a new door for the detection of the case.It is worth mentioning that Sun Zhongsheng's lover, Li Songzhi, is also a policeman, a model of Beijing's public security system.The problem is, because he knew that the police were arresting him, after "Scud" committed the crime, he paid great attention to cleaning up the traces.In the previous case with "Scud", the place where the "Scud" moved was either in the paddy field or on the asphalt road, and its clear footprints could not be obtained.

The hard work paid off, and the opportunity finally came.After Sun Zhongsheng joined the investigation of the case, one late night in the winter of 1976, Xiao Weimin's team, who was squatting on guard, confronted "Scud". According to Lao Sun's recollection, Xiao Weimin reported that the encounter with "Scud" was at two or three o'clock in the middle of the night. After the two sides fought against each other, the old and cunning "Scud" turned around and ran away.After the police shouted in vain, they found that the other party was running away, so they started to chase. Because it was too dark and the terrain was complicated, the pursuit ended in failure.

Since it was mid-winter and the ground was hard, it was very difficult to track down the perpetrator.However, after dawn, Xiao Weimin and two team members patiently tracked and followed the traces left by the criminal, and they still accurately tracked two kilometers to the east of Shuangqiao Railway Station, 300 meters away. Next to the small village of Xianninghou Village.After chasing here, Xiao Weimin suddenly smiled.It snowed a few days ago. Due to the wind direction, the snow in some places around Xianninghou Village has not yet melted, and there is still one to two centimeters of residual snow.

On the snow, the criminal's footprints suddenly appeared! "Call the little god." Xiao Weimin carefully protected these footprints, and at the same time called the command with some pride. "Little Immortal" Sun Zhongsheng arrived immediately and began to analyze the criminal's footprints. An unexpected result appeared: this person, judging from the stride length, should be between 1.50 and 1.90 meters tall - this has no reference value at all. You must know that Sun Zhongsheng usually judges a person's height. There is only a difference of two centimeters at most; this person, judging from the depth of his footwork, should be a fat man like a meat ball, but this is completely inconsistent with the suspect described by the victim, Xiao Weimin and other scouts completely disagree :

"If it was a big fat man, we would have caught up with him long ago." The center of gravity of its footprints is also suddenly forward and backward, which is very strange.The little god who usually does analysis well and soundly, was completely stumped this time.However, he still analyzed the person's course of action: After this person arrived in Xianninghou Village, he ran around a villager's yard in circles, making his footprints very messy.This vicious circle similar to an endless loop made Sun Zhongsheng spend a lot of effort before he found a very inconspicuous footprint, going straight to the tunnel of Shuangqiao Railway Station, and finally disappeared on the roadbed paved with coal gangue.

Ma Zhongsheng speculated that the perpetrator disguised the footprints in order to disrupt the police's tracking.Some helpless little gods took pictures of the footprint samples and sent them to the old gods.Later, Ma Shenxian wrote back, and his analysis of these footprints showed that the perpetrator had indeed camouflaged the footprints. Among the footprints circling the villagers' houses, some were walking forward but jumping, and some were walking backwards. There are also people who walk diagonally with their feet in their shoes.His stride became extremely erratic due to hopping, and his center of gravity was reversed due to walking backwards.Even, the criminal was carrying heavy objects on his back during his escape, which made it difficult to judge his weight.Unfortunately, at that time, Ma Shenxian was already in very poor health and passed away soon (the case had not been solved at that time), so he could not provide more help in this case.

Could it be that this kid is a guy who is very familiar with public security reconnaissance, and he actually knows how to set up suspicious positions to interfere with our investigation of footwork?Moreover, he dared to run around the villager's house when there were soldiers chasing after him. This person is really brave enough.Afterwards, the police realized that this was only because the way of thinking was different from that of the criminal. The police looked highly on this "scud".He set up doubts around the house, just because he suddenly found that there was snow under his feet, he jumped up and down just to mess up his footprints, he kept changing his center of gravity so that people in the house would see him, and he carried heavy loads just because There was something he had robbed near the house, and he had to move it so the police wouldn't see it.Wearing his shoes backwards was intended to mislead the police, but he was circling the house for another reason entirely: he was worried that the footprints in the snow in front of his house would attract the police.

The police did not notice that a veterinarian lived in the house surrounded by "Scud" in Xianninghou Village. Not far to the south of Shuangjing Bridge today, there used to be a veterinary station (now demolished) on the east side of the river. Most of the older people still remember this place.Someone will even tell you that there are two veterinarians in that veterinary station: one is very old, and the other is a very ugly one named Li. This veterinarian surnamed Li lives in this house in Xianninghou Village. In 1973, veterinarian Li Baocheng was once listed as a suspect in the "Scud" case in Shibalidian, but he was not taken seriously because his residence was too far from the crime scene.There is another reason for not being able to investigate further: During the investigation, the public security officers let several victims listen to the suspect's recording, and no one had any abnormal reaction to Li Baocheng's recording.

If some of the police are familiar with the work of veterinarians and know that some veterinarians control the throat muscles to imitate the sounds of animals to obtain "communication" during treatment, they may pay more attention to Li Baocheng.However, since none of the victims could recognize Li Baocheng's voice, the suspicion against him could not be upgraded.At that time, there were too many suspects around, and all of them could not be controlled by surveillance.However, after the case was uncovered, it was confirmed that this Li Baocheng was exactly the "Scud" and "Shuangqiao old hooligan" who had troubled the headhunters in Beijing for ten years.

Li Baocheng, born in 1944, is a native of Xianninghou Village. He is usually evaluated as "serious in his work and enthusiastic in his work".His wife is from Xianghe County, Hebei Province, and often works night shifts, causing their sexual life to be inharmonious.At the same time, it was precisely because his wife often worked night shifts that Li Baocheng was provided with excellent conditions for committing crimes.After the incident, Li Baocheng's wife was very surprised, and the police believed that if her surprise was acting, she would have won the Hundred Flowers Award. Because he is a veterinarian, Li often travels from village to village to inspect livestock in farmers' fields.Therefore, he is familiar with almost all the remote paths and passages in the paddy and dry fields in the local area, and he also knows the family situation of the victims in each township and village.In addition, at the veterinary station, he has to provide treatment for the livestock of farmers in various villages. During the chat, the farmers often reveal news such as "the police came to our village to catch 'Scud'". The situation of the police arming.These all laid the groundwork for Li Baocheng's inability to be brought to justice for ten years. What's interesting is that Li Baocheng, a veterinarian, doesn't treat dogs.Then why is Heibei so afraid of him?This is also where the police did not understand at first.It wasn't until I learned some veterinary knowledge during the interrogation that I understood why such a strange thing happened.It turns out that in the veterinary profession, the main drugs used by dogs and horses are the same.Although people can't smell Li Baocheng's smell, dogs can tell it.Dogs, like children, are reluctant to deal with things like people in white coats, injections and medicines.To put it aside, in the pet hospital, dogs enjoy it more than people, and they don't have any dislike for doctors.But that was during the movement, and humanitarianism was unreliable, let alone dog ways.If there is something wrong with the dog, the treatment is generally simple and rude.So as soon as he smelled this smell on Li Baocheng, the dog's fur immediately stood up. As for the fact that the dog trainers did not chase after the dog, the dog also had its own reasons: you are a master who is loyal most of the time, but when you meet someone in a white coat, you will be a traitor to your mother. Don't cover me.This time I was forced to look for a white coat again, either for vaccinations or enemas, nothing good would happen!I will not go…… Li Baocheng was also quite afraid of police dogs at first, but later found that the dogs trembled when they saw him.After all, he had worked as a veterinarian for many years, so he immediately understood his deterrent to dogs, and immediately became courageous. The thing that made the "little fairy" dizzy turned out to be like this: Li Baocheng fled in embarrassment after encountering the police. Seeing that he ran to the door of his house, he suddenly found that there was still unmelted snow around him, and his name was clearly printed on it. "God, didn't I bring the police home?!" In a panic, Li Baocheng ran around the house, jumping and trampling his footprints, hoping to confuse the police.He also carried the stolen food sack placed at the gate and hid it in a nearby field through the culvert next to the Shuangqiao Railway Station.Then...then it was almost dawn, and he didn't go home anymore, he went directly to work at the veterinary station. Naturally, the police failed to find his footprints back home, and made him shrink back on the threshold of exposure. Bold, agile, familiar with the local conditions, accustomed to disguise, and has never dealt with prisons, his thinking has nothing in common with habitual criminals, allowing Li Baocheng to escape the police trap time and time again. From winter to spring, despite a lot of effort, the "Scud" in Shibalidian was still missing, which brought great distress to the police officers who handled the case. Around the 1980s, there were fewer major cases, and the early 1980s was the golden year for China's public security.The thirteen divisions are separated, Zhang Liangji has a new job, but he is so worried about the "scud" in the Shibali store that he issued a military order and took the case away, which shows how awkward he was with this case . The "Scud" in Shibalidian has become the wheat city of the Beijing police.Lao Sun said that he did a very tedious thing at that time, which turned out to be the greatest contribution of the police to the cracking of the case: the police, based on the criminal characteristics, traces left behind and the target of the crime, collected more than 300 cases at different times and in different locations. The cases were summarized together and set up as a dossier.According to the conclusion of the police, these cases should all be committed by one person, so everything was broken. Originally, I wanted to write more about the ups and downs of the failed police officers. After reading a paragraph of text, I thought it would be better not to add superfluous things to the police.This text was written by a brother of ours who was a policeman. From the background, it seems that there is a "professor" who shared the joys and sorrows with the police comrades. After some investigation, he wrote a report to talk about the hardships of the front-line policemen, and published it in the internal public security journal.Ordinarily, this is a good thing, but when the police saw it, they were almost stunned. It turned out that this "professor" wrote: "More than 90% of the policemen in this province have occupational diseases such as stomach problems and arthritis. Almost all the front-line policemen are sick, and those who are not sick are all new to work." Writing here, even if we say that we are sick, the police can still accept it, after all, they are kind. However, looking further down: “One-third of the front-line policemen suffer from different degrees of mental illness symptoms due to high psychological pressure, and half of these one-third are completely consistent with the symptoms of mental patients.” The police comrades concluded: By analogy, our country largely relies on lunatics to maintain social order.Afterwards, some bored people from the bureau's office and the political department analyzed the police list to see if they could find 30 lunatics in the overall situation... It can be seen that, for laymen, sometimes praise is not good. Just focus on the case. In other words, after 1979, the "old hooligan" has been quiet for quite a long time. When the police met and talked about it, they all had a bad guess: this old boy is probably too old to work, and it is not good to make trouble. It would really let him get away with it for the rest of his life.As he was talking, Lao Sun did not expect that an unexpected opportunity hit him on the head like a brick.Old Sun said it was evil, the case was solved because the Public Security Bureau wanted to rectify the party...
