Social evolution has been evolved today, human beings have the ability to transform and resist nature, but it is difficult to get rid of the threat and disaster from human beings. Such as terrorist events.

The common way of making horror is explosion, without warning, it is difficult to prevent. The scene after the frying was tantamount to the ruins of a war. Fortunately, my country's public security organs continued to control high pressure on explosive items, and related malignant cases have become less and less.

There are many experts in the anti -explosion team of the Chinese police community, especially the older generation of experts. It is because they are "one foot tall and one foot high", and many seemingly unsolved cases can only be obtained. Surveying. One of the first eight "invited criminal investigation experts" of the Ministry of Public Security was one of them.

Highlight is doing experiments

To be honest, it is difficult to interview high -light fighting. He is too rational and objective. He always said with his nice voice and in order to say: "I have participated in the on -site inspection work of the ×× bombing case", "a person's role is insignificant, it is a case that everyone breaks together" and so on. Indeed, he is not the thrilling hero. He is a talented and scholar, and he is so wise and heavy. I just need to record his extraordinary stories.

Most of the media called Gao Guangdou as a "blasting expert", so I just sat down in front of his desk, and he said, "To solve a conceptual problem first, others say that I am a blasting expert. In contrast to the blasting project, in the face of the end of the explosion, using reverse thinking to reverse the initial state before the explosion to achieve the purpose of solving the case. "Then he recalled the explosion of the explosion of the Shijiazhuang Mianxiang dormitory building.

From 4:16 am to 5:01 am on March 16, 2001, five buildings in Shijiazhuang City, Hebei Province exploded one after another. The scene was like a fierce war. There were 108 people on the death list. The 86 -year -old man, as well as a baby to be fed. This extremely rare case since the founding of the People's Republic of China has attracted great attention from the Party Central Committee and the State Council. The Ministry of Public Security mobilized the national elite forces to invest in case detection.

Gao Guangdou called the detection of explosions a "anti -push system project". In the "Engineering", there were 7 investigating cases, and the Ministry of Public Security of the Ministry of Public Security invited criminal investigation experts in the Ministry of Public Security was incorporated into various groups. The survey and inspection team where the highlights are located have conducted a comprehensive investigation of the fried point position of each explosion site. His work is mainly to "rebuild" the scene in the process of "anti -push", so that this highly disorderly ruins step by step anti -countermeasure Push back the initial state of an instant. He used the collection of physical evidence to analyze the explosive ingredients to determine what explosives were; based on the distance and the size of the bleeding pits, the amount of explosives was estimated to analyze and judge the explosion center.

In order to obtain evidence, they were large as large as the cement board, small to the surrounding dust, and crushed objects. They were investigated and screened with small sister -in -law to find the explosion leftover. Finally, it is inferred that most of the explosive centers at the explosion site are in the corridor; the explosive composition is the same as that of the explosive device; except for the large amount of explosives, except for the large amount of Building 15, the amount of Building 16 is small, and the remaining several places are basically the same. This inference combined with the related personnel involved in the five explosions, the criminal suspect Jin Ruchao eventually locked the criminal suspect. This person was imprisoned for rape. After the release of his prison, he did not know repentance after being released.

After the case was cracked, Jin Ruchao's confession confirmed the in turn confirmed that the judgment of the highlights and his group's judgment on the explosion center, the nature of explosives and the amount of dosage were basically correct.

At about 3 am on July 16, 2001, an explosion in Ma Fang Village, Dangcha Town, Hengshan County, Shaanxi Province, was also a "war". There is a basketball court as big as a pit. Half of the villages are almost razed to the ground. More than 20 houses, 311 houses are damaged, and more than one hundred casualties.

The explosion center is the home of the villager Ma Shigui. When Gao Guangdou and other experts arrived at the scene, the villagers rumored that the cause of the explosion was that Ma Shigui had an affair and a crack in the relationship with his wife. Therefore, he fled the explosives in the yard in the middle of the night and killed his wife and four children.

The relevant departments sent 100 armed police to assist in the work. Gao Guangdou "trained" on the spot for 5 minutes, and asked these armed police soldiers to help find corpses in the ruins. To be precise, it is a human tissue of meat blocks and bone blocks -walnut size or slap size. According to the exact position of the Ma Shigui family in the moment before the explosion, the search direction was determined. In the first round, 49 tissue blocks were found, most of which were walnut size, and many of them were broad beans. After a forensic doctor's DNA test, it was confirmed that the 6 family of Ma Shigui died of the explosion, which excluded the possibility of Ma Shigui. The murderer had another person.

Faced with the fierce scene, Gao Guangdou observed at the scene and around him for a while, and decided to take the type of explosive on the roof at medium -distance distance from the fried point. One, the distance between this roof and the scene is exactly where the explosive residues are densely distributed; second, the dust on the roof is less polluted, which is conducive to the test results. If the soil test from the ground, because the villagers have been in interest here for many years, the decomposition products of the people and livestock excretion in the soil can have the same substances as the explosive ingredients, which will inevitably affect the test effect. After experimental analysis, the variety of explosives determined by highlights is a nitrate explosive containing diesel. At the same time, it is estimated that the final explosive volume is about 30 tons. This estimation result played a positive role in the direction of the investigation. First of all, this kind of ammonium nitrate explosives are local explosives produced locally. Many villagers in the village and nearby are manufactured. The elder brother of the victim Ma Shigui opened a soil explosive factory on the mountain. If this case is artificially detonated, the crime person is likely to have something to do with the local explosive factory. Secondly, such a large explosive amount may also have something to do with some contradictions in the explosive industry. It should be investigated around the local or nearby explosives.

After the work of the local criminal police, Ma Shigui's elder brother Ma Shiping surrendered to the local public security organs to report on his home -made more than 30 tons of ammonium nitrate explosives in his home, and revealed the suspicion of the villager Ma Hongqing in the village. The investigators found that Ma Hongqing had a loss of business for years. Due to his poor character and poor reputation, no one cooperated with him, and he would vent his dissatisfaction to Ma Shiping, who was usually contradictory with himself. At around 3 am on the 16th, Ma Hongqing carried a fuse and detonator, and rushed to the back wall of the small kiln of the soil nitrate explosives of the Ma Shigui, stretched out a small hole in a bag of explosives from the window, inserted the detonator into explosives into explosives. In the middle, the fuse connected to the detonator was ignited, and soon after returning to the scene to return home, the explosion sounded.

In 1999, a private long -distance car in Jinzhou exploded during driving. There was no spared person for exemption. More than 10 deaths were killed, and the remaining personnel were injured to varying degrees.

The explosion occurred at night, except for the driver, passengers were in the dream hometown. The sleeper on the car is narrow, and people can only curl up to sleep. The highlights measured that the center of the explosion was on a sleeper in the front of the carriage. The female passenger's abdomen and legs on the sleeper were severely blown up on the front of her legs, indicating that the explosive bag was surrounded by her abdomen and thighs. If this female passenger is suspected according to the basic experience of the past. However, Gao Guangdou did not easily conclude. In the investigation, a black wire was found from the female passenger's sleeper to the back of the car. Why does the wire connect to the rear of the compartment? If this female passenger's suicide explosion, there is no need to use such a long wire. In addition, the people in the front of the carriage were seriously casualties, but the people in the back of the carriage were all minor injuries. In this regard, he believes that the suspect may be someone in the back of the carriage.

As a result, the investigators checked the wounds of all the wounded one by one. Almost everyone's wounds were exposed to exposed parts such as chest, limbs, or hips. Only one person's injury position was special: underarms and foot plates.

Highlight fights working in laboratory

After discussing with forensic doctors, it should be done by this person! When the explosion occurred, he would only cause injuries to the armpit and soles of the feet when he hugs his head and lying on his head. Why does he have this posture? There is only one explanation, he knows that the explosion is about to occur, and the heart of self -protection makes it.

The policeman asked the person directly: "What posture do you post in the explosion?" He replied, "Lying on your head, holding his head." The police said, "Then you talk about lying on his head and holding his head?" He had to admit that the explosion was made by him.

Highlight fights at the "5.7" air crash.

The "positioning -qualitative" mode is also successful in air crash analysis. After the "5 · 7" air crash in Dalian in 2002, the highlights followed the expert group for 40 days in Dalian. During the day, he and other experts measured the calculation of the crashed aircraft model, learned experience, and exchanged opinions. In the evening, before he drawn the "Flat Map of the Furious Plane" he painted, he positioned each killed passenger one by one. Under the cooperation between the public security, civil aviation, and the relevant experts of the Chinese Academy of Sciences, it finally accurately qualified the air crash.

Many of the scientific methods used on the scene on the scene are his own invention and creation -from the method of on -site exploration equipment, drugs and extraction samples, to the rapid inspection method of the laboratory, calculation formula, etc. Most of them are the original, effective, or even authoritative methods that he summarizes his predecessor's experience. This is the amount of the expert in Gao Guangdou!

In 1981, he first cited the electrode technology to detect the inorganic component of the explosion case and achieved good results;

In 1982, a trace explosive spray appende was successfully developed. When the test site was detected, the common trace organic explosives were shown in the color of the spraying agent developed. This result won the third prize of Beijing Science and Technology Progress;

In 1983, he was inspired by the concept of environmental protection and science. First, he first proposed a new concept that separated the existing relics from the residues, and formed the first and only explosive analysis research room in China. Persons' research on the basic laws of the distribution of explosive residues has completed the research of the basic laws of the distribution of explosives. The results of this similar mathematical issue make the extraction of explosive residues faster and accurate;

In 1986, he summarized the empirical formula of using the trauma area radius to estimate the amount of explosives -he was called the "experience formula", which was actually another innovation, because this formula was he explored and refined from many explosions. For the first time, using this calculation formula can calculate how much the criminal suspect uses the amount of explosives, it can be said that it has filled a vacancy of my country's criminal investigation science and technology. Highlights are detecting explosive certificates

As we all know, the explosive engineering technology is a very mature field. The performance characteristics of explosives and their related issues are almost studying by their predecessors. In the absence of previous people who can learn from knowledge, it is very difficult to obtain a new breakthrough in the actual problem of solving the application type in the scene of the explosion, especially if it is very small creation. Therefore, it is not difficult to imagine how much Gao Guangdou has achieved the above results.

During the study of the basic laws of the distribution of explosive residues in design leaders, he and his colleagues of the Institute of Criminal Science and Technology of the Beijing Public Security Bureau used different dosage to do more than ten explosion tests in the suburbs of Beijing. After each explosion test, the back of the laboratory on the edge of the pit and peripherals is densely taken back to the laboratory for physical and chemical analysis to summarize what density explosion residues are distributed. A year later, the soil they memorized was more than two tons, and they got a convincing result.

After reading this, the highlight fighting in your mind must be an expert in an explosion case analysis. In fact, this is not the full picture of the high light fight. He has written a paper entitled "Thinking Innovation and Investigation Practice", which is his research and sublimation of public security technology and the personal experience of the police for many years. Gao Guangdou had been the captain of the Interpol for 4 years, and personally guided and participated in the detection of criminal cases of heavyweight. He had the experience of criminal police case handling and also had the characteristics of a criminal police.

He said in the paper: "Inspirational thinking is not superstition, it is a return on hard work. It is based on logical thinking and image thinking. Under the subconscious The spark of inspiration is the most rare and valuable form in thinking. Every investigator and commander of each battle has experienced inspirational thinking experience. "

In 1987, when the director of the Criminal Science Institute was the director of the Criminal Science Institute, he received visiting American colleagues.

For example, in Wuhan's "Valentine's Day Explosion", he flew to Wuhan and changed the police car to the majestic Wuhan Yangtze River Bridge. When he was beautiful outside the window, his inspiration appeared and he was caught. Beauty is very suitable for a person who is a "home".

Gao Guangdou was not "nervous", and he thought of the explosion of the Beijing Railway Station in October 1980. The explosion killed 9 people and more than 80 people were injured. On the 8th day of the case, the investigator found a testament he wrote to his friend at the residence of the criminal Wang Zhigang: "Although the place I went to, it was not ideal, but after all, it was a destination."

After repeated testing, Gao Guangdou believes that there is inspiration in the world. The "Valentine's Day Explosion" is similar to the explosion of the Beijing Railway Station. The suicide explosion is obvious. Those who are determined to die will generally design a "destination" for themselves. These two cases occurred on the "road". They are both the roads and the end of life, and they are all famous places. All are young "fearless" life; the variety and explosive amount of explosives must be set to death ...

After the "Valentine's Day Explosion" was detected, the investigator found his legacy at the suspect's house: "In a beautiful place, ending my not beautiful life." Like Wang Zhigang's suicide note.

Gao Guangdou believes that on -site surveys and investigations are inseparable, and survey is investigation. He made a obvious contribution in the analysis of the explosion case. The editor -in -chief "Survey Technology Science" has also been released. However, he is not satisfied with the discipline of the explosion analysis. He uses his enthusiasm for the public security cause and all wisdom to be a police officer. He said, "I am not an expert, but a miscellaneous family."

The dedication of Gao Guangdou lies in his ability to cultivate a new generation of explosion case analysts. Beginning in 2001, while handling the case everywhere, he continued to conduct lectures on the "detection of explosive case commanders training class" in various places. Many people are all criminal scientific and technical commanders and backbones in various places. They can be described as the world. Perhaps in the future, some of these backbones will become an analysis expert like him.

Gao Guangdou felt that such a lecture method was very good at his heart. He said: "I am not satisfied with the form of a master with a apprentice, but likes to transfer to 'retail' for 'wholesale'." Gao Guangdou has a sense of responsibility to cultivate successors. And the sense of urgency, although the current young people have a strong operation ability, due to the limitations of various factors, it is difficult to find the vacuum or blank spots in academic or work. Experts like him bring them more. Highlights' homes are not different from the vast majority of happy families: he and his wife are dedicated and loved their homes. If you have to say different places, that is, the home of the highlight is full of scent and academic atmosphere, and there is no trivial and secular taste.

Gao Guangdou's wife was originally a Shanghai girl. At the age of 14, she followed her brother who worked on the railway to Gansu. When she met her mother, she also went to Gansu with her mother. Gao Guang Dou is good at learning. He has his own claims in the event of an incident. He is handsome and handsome. Naturally, he has a good impression in her heart. And her outstanding performance and beautiful and dignified, she also made Gao Guangdou look at each other. After graduating from high school, the two thought they would be different, but did not expect that Gao Guangdou was admitted to the Department of Chemistry of Lanzhou University. She was admitted to Lanzhou Medical College, and only one wall was separated by two universities.

They transferred from green plums to their first love. They were not easy and romantic. When Gao Guang fighting in college, he had made dissatisfaction with "big steel" and "Great Leap Forward". During the 5 years of college, he was criticized for 3 years. Other students alienated him, and she always believed that The high light bucket is correct. At this point, the beautiful impression that stayed in each other in the middle of the middle school was clear, and they fell in love.

Highlights when you were young

After graduating from college, Gao Guangdou was assigned to the Beijing Public Security Bureau for criminal science and technology, and she stayed in the Gansu Tianshui District Hospital as an obstetrician and gynecologist. That year, they got married, and they lived for 7 years after marriage. Highlights originally expected to adjust their wives to come to Beijing to reunite. They did not want to be decentralized to plant grapes at this time.

At this time, the state engaged in the "three -line construction", and the Beijing switching plant assisted the construction of the "Great Wall Switch Factory" in the construction of the Tianshui Construction of Gansu. The high -light fights who were unwilling to discard the business decided to return to Gansu Tianshui with the third -line construction project. At this time, the central government instructed the talents of the original front of each front, especially the talents in the public security industry to "return to the team." Gao Guangdou returned to the Beijing Public Security Bureau for 11 years in 1980. The family also came to Beijing together. The wife was placed in the public security hospital and still became the bank of an obstetrician and gynecologist.

The big tree of the highlight fighting career began to harvest fruit after returning to the Beijing Public Security Bureau. When he returned to Beijing, he quoted the electrode technology to the on -site detection of the explosion. This was very advanced at the time. In the second year, the successful trace explosive spraying agent was developed. In the third year Essence

Echo his achievements in his career one after another. His wife is also excellent in the unit. Because of the good medical ethics, many patients come to see her to see a doctor. Gao Guangdou praised his wife with him "very well in his career." His wife is a career -oriented woman. She despise the mediocre people and never complain about her husband's busy year.

Of course, Gao Guangdou also has his own mood. He likes to read various books, pay attention to various information, like to play and sing, and love to blow the piano. That is the hobby of his student days. In the event of a unit engaged in the joint event, he blows up the piano to accompany everyone. Sometimes when he is too tired to adjust, he will also take out the treasures of the saxophone tube and blow a few melodious old songs. At that time, he would temporarily forget the scene of the bombing of Lin Lin for the time being.

"Miscellaneous Family" is exactly the depression of highlights -there are many expertise experts: 4 years of Captain Captain, Director of Criminal Science and Technology Research Institute, 5 -year Science and Technology Division, 40 years of criminal investigation science and technology research, The current vice chairman of the Beijing Institute of Technology; the Ministry of Public Security invites criminal investigation experts to directly participate in more than 30 accidents and investigations of the Great Bang Cases; the leaders have completed 6 public security science and technology issues that have nothing to do with the bombing case and 2 public security science and technology projects; Xiang State Invention Patent; Winning two Beijing Science and Technology Progress Awards; scientific and technological management experts with outstanding contributions ...

The performance of the highlight fighting is the spirit, quality, moral, human light, and vitality of life vitality that transcend these things -the people who create hero performance.

The Ministry of Public Security invited criminal investigation experts to take a group photo (three high light buckets on the right)

On September 2, 1999, when the Ministry of Public Relations of the People's Republic of China announced the first batch of "criminal investigation experts" hired by the People's Republic of China, he used eight words to evaluate high -light fighting: "with excellence and meritoriousness."

The highlighting name is actually deserved.
