The explosion shocked * * *

Mysterious explosion of mining and pharmaceutical factory

The tragedy shocked * *. * * * "Security Minister" Mao Renfeng gloated.

Play black humor; Soviet experts painted this land as a prison.

Make the case complicated. Detectives are observant.

The truth finally came out.

1950 June 14

The second session of the first Committee of China People's Political Consultative Conference was grandly opened in Huairentang.

4: 00 p.m sharp

Chairman * * * and Vice Chairman, Li, Shen Junru, Guo Moruo and Chen Shu are equal.

Stepped onto the rostrum with warm applause. Secretary-General Li declared the meeting open. * * * After the Chairman made a statement, members of CPPCC made statements. At the end of a speech by a member of the democratic party from southwest China.

When Zhou Enlai, who was sitting next to him, stood up and shook hands with him.

Suddenly, there were two loud noises on the east side of * * *.

Like a gust of wind blowing

The quiet venue rippled like a spring. It was quiet for a moment.

* * * glanced at the audience.

smile faintly

"Comrades, please continue to speak."

Zhou Enlai quickly wrote a line on the paper.

Give it to the staff. 10 minutes later

The staff also reported to Zhou Enlai in the form of a note: 5: 20.

There was a big explosion at Heji Mine Pharmaceutical Factory in Hua Fu.

Casualties and the cause of the explosion are unknown; Public security and firefighters have arrived quickly.

Is being rescued at the scene.

For more than 50 years,

This explosion has become one of the most serious explosions and fires in Beijing since the founding of New China. Just after these two loud noises were introduced into Huairentang.

Black smoke billowed over the pharmaceutical factory of Hua Fu Hutchison Mining Bureau.

Up into the sky. According to eyewitness accounts afterwards.

The scene was a mess.

The fire raged.

In the thick smoke, telephone poles, branches and limbs of victims hanging from the ruins can be seen faintly.

The blood of the dead and wounded splashed on the ground and walls.

It's really scary.

After 6 fire squadrons and other personnel 10 hours of hard work.

Fire caused by explosion

It was all put out in the early morning of the next day. According to the data.

The explosion caused great losses.

39 people died (including 32 citizens and 7 employees of Heji Mine and Pharmaceutical Factory in Hua Fu).

406 people were injured; A total of 497 houses collapsed.

1928 rooms partially collapsed.

On the same evening

Luo Ruiqing, Minister of Public Security, Peng Zhen, Secretary of Beijing Municipal Party Committee, and Nie, Mayor, immediately instructed the Beijing Public Security Bureau to quickly find out the cause of the explosion.

If it is really destroyed by enemy agents.

We must file an investigation immediately.

Arrest and punish severely.

The Beijing Municipal Public Security Bureau received instructions.

Deploy immediately

The next day, 17 scouts were sent to form a task force.

The first thing after the establishment of the task force

Is to analyze and determine the cause of the explosion. A Soviet blasting expert named Matvei Ye Fu was invited to visit Hua Fu Hutchison Mining Pharmaceutical Factory.

Hua Fu Hutchison Mining Pharmaceutical Factory is a private enterprise owner and the 208th Military Division of North China Military Region, which specializes in producing mine explosives and detonators. June 15 pm

Matvei Ye Fu explored for more than two hours.

It is believed that these two loud noises were caused by two small explosions.

The explosion sites are the decoration of finished explosive charge and the packaging point of detonator. Both belong to the finished product workshop of the factory.

The positions are about 30 meters apart. Discovery

There is a big pit 7 meters long, 3 to 4 meters wide and about 1 meter deep under the site 1; There is a bigger and deeper pit under the scene 2. This is all that's left after the explosion.

When the explosion happened, Matvei Ye Fu asked the factory about the product storage in these two locations.

On this basis, the destructive power of the explosion is accurately calculated.

Finally draw a conclusion

The first explosion was the detonator packaging point.

This led to the explosion of the finished explosive.

That afternoon

The task force held the first case analysis meeting. Matvei Ye Fu analyzed the scene of the explosion for the scout.

Several possible detonation modes are also explained. Matvei Ye Fu said firmly.

The explosion was sabotaged. He stressed

Pay special attention to the following two detonation modes.

One is a time bomb.

Second, phosphorus chemicals such as white phosphorus and yellow phosphorus are artificially ignited or spontaneously ignited.

The contingent accepted the advice of Soviet experts.

The residue from the explosion site was extracted and sent to Tsinghua University for composition analysis. meanwhile

The task force is busy looking for clues about the people who left the finished product workshop before the explosion.

Fortunately, at the suggestion of the military, the factory

The registration system of origin entry and exit was implemented five months ago.

All production workshops are guarded.

All personnel entering and leaving must register the time of entry and exit with the doorman. The concierge and two explosion points in the finished product workshop are just dead ends.

The doorman just hurt his ear a little. Fortunately,

He took the register with him when he fled the scene after the explosion.

fast

Chemical experts in Tsinghua University produced the analysis results of the evidence obtained at the explosion site: in addition to the metal composition of the detonator itself, the No.2 scene

No other metal objects were detected; No metal objects were found at 1. in other words

The explosion was not caused by a time bomb.

The task force analyzed accordingly.

The possibility of open flame detonation (refers to the explosion caused by directly igniting explosives with matches, lighters and other open flames) is almost zero.

This leaves only the possibility of spontaneous combustion and explosion of phosphorus chemical workers. Considering the working environment on site

It is estimated that the time to release phosphorus chemical workers will not be too long before the explosion time.

Otherwise, it is easy to be found. therefore

The task force decided to rule out the logistics personnel among the suspects first. Other personnel

Make a list.

Then investigate separately.

After the scheme is determined

The task forces are out.

I went to several hospitals separately to visit the seriously wounded. June 17 pm

The investigation has been completed.

After the analysis and appraisal of the task force

Three suspects were initially identified.

Xiao dingtian

Workers in this factory. June 14.

He didn't eat at noon

A look of anxiety. in addition

He usually leaves dangerous goods (such as matches, lighters, cigarettes, keys, knives) before going to work in the morning.

And lock metal objects such as silver rings into a box fixed by everyone)

Dally, deliberately left behind. When I went to work that afternoon,

No one has seen what he is doing since half past three. After the explosion,

He limped away from the scene with a burned leg.

Got on the bus that came to the rescue.

Get out of here.

Zheng Xinmin

Technician, 208th Division, North China Military Region. June 14.

He never enters the workshop after 3 pm, so he is uncharacteristic.

I entered the workshop at 4 o'clock. According to the workers at the scene No.2 at that time,

Said he saw him wandering around there.

Play jokes on the packers from time to time. Shortly after he left.

There was an explosion.

Ding Songlin

In the finished product workshop of Hutchison Mining Pharmaceutical Factory in Hua Fu, I made a living by moving wooden boxes. He is the only lucky person in the finished workshop who is not injured except the doorman. Ding's job is on site 2.

This should be a narrow escape.

This is very strange!

The task force decided that

Summon Xiao Dingtian, Zheng Xinmin and Ding immediately!

June 18 pm

Xiao Dingtian came to the East Suburb Public Security Bureau alone. He is wearing a suit and tie.

I came by rickshaw.

Holding a bag in his hand. His clothes and manners.

The scouts coming from the ravine froze for a long time.

The trial begins. The investigator asked, "Xiao Dingtian.

Do you know why I called you to the precinct? "

Xiao Dingtian looks like he has answers.

Looking at the investigator calmly replied: "I know! I must suspect that I have exploded. "

"You can say that.

Are you guilty? "

Xiao Dingtian replied: "It's not a guilty conscience.

I'm afraid you'll arrest me before asking me questions. "

"Do you think we are such people?"

Xiaodingdian smiled: "That's good.

I can tell you.

I had nothing to do with the bombing! "

Speaking of which,

Let's cut to the chase.

The investigator asked him to answer some questions. Xiao Dingtian is poised.

11: "I didn't have lunch that day."

Because I'm very upset.

Put things away when you go to work and enter the workshop.

I'm checking the hanging watch.

I suspect it is lost. Then I went to the hospital to dress the wound and went home to see it.

I didn't lose my pocket watch.

I feel very at ease. "

"After half past three that afternoon.

Where are you? "

Xiao Dingtian thought for a moment: "I'll go to the infirmary.

I didn't return to the workshop until after 5 o'clock.

No sooner had I got back than there was an explosion. It would be nice if I went back later. "

The investigator immediately found the flaw: "Why doesn't the doorman have a record of you going in and out of the finished product workshop?"

According to Xiao Dingtian's explanation

When he left the workshop that day

The doorman is not in his post.

He came out. When I go back,

I did meet the doorman.

But I heard him say something he didn't see when he came out before.

Tell him not to register.

Xiao Dingtian said it easily.

This makes investigators nervous: if the doorman really works like this,

Are there any other loopholes?

An investigation was launched immediately afterwards. Go to the infirmary first

ask

What Xiao Dingtian said is true. such

We can preliminarily rule out Xiao Dingtian's suspicion. soon

For example, Xiao Dingtian.

The interrogation of Ding and Zheng Xinmin did not find any doubts.

June 23(rd)

10 days after the explosion.

The telecommunication investigation technicians of the Beijing Public Security Bureau intercepted a secret message from the Security Bureau of the Ministry of National Defense of Taiwan Province Province.

The decoded message is as follows: "609" Congratulations on the success of the bombing operation in Peiping carried out by your regiment.

According to the order of the chairman, the seat of the presidium has been granted.

A special envoy will leave for Pingping in a few days.

The secret news caught the attention of the public security department.

The leaders concerned ordered an immediate investigation. the next day

Telecom investigators intercepted a secret message again.

It is aimed at the technical problems of explosion to "guide" "609"

It is said that this is the opinion of American experts. This secret message is 3654 words long.

The technical data, casualties and losses listed in it.

There was no public disclosure at the time. This initially confirmed the judgment of the task force at the first case analysis meeting: the explosion was indeed a spy!

The Beijing Public Security Bureau quickly dispatched eight investigators and set up another task force.

Communicate with the original investigation task force

Close cooperation. but

Separate investigation of cases. For the convenience of narration

We call this task group "the second group".

The second group has a cryptographer.

After taking over this case,

He immediately studied the two secret messages.

It turned out that something had happened. first

When the secret service of Taiwan Province Province contacted the spies lurking in the mainland by radio.

Generally, two sets of passwords are used in turn.

That is, this time with password a.

Use password b next time. Over a period of time

Change both sets of passwords again. in addition

And a backup password.

In case of emergency. These two secret messages

But uncharacteristically violated this rule.

Two secret messages use the same set of passwords; second

The cipher group used in these two secret messages.

Deciphering is extremely difficult.

It is basically a copy of the password used by the enemy radio station found at the beginning of the year; third

Two sets of passwords use the same radio frequency.

This is usually not used by enemy spy agencies.

Because it is easy for us to listen.

In view of these three points

Experts believe that

Secret information may be intercepted, intercepted and deciphered by us on purpose. He talked about his views to the person in charge of the project.

Could this be the intentional behavior of the enemy?

To confuse us? If it is.

There may be other reasons in this case.

The task force believes that

The data listed in the second telegram has not been published.

Few people know.

We can start with this clue.

The survey was conducted jointly by two task forces. 1 Team is responsible for investigating the situation of Heji Mine and Pharmaceutical Factory in Hua Fu.

The second team is responsible for investigating the situation outside the factory.

Group L analyzed the data in the second secret telegram.

Confirm that this is from the inside of the pharmaceutical factory of Hua Fu Hutchison Mining Bureau. After the factory exploded,

In view of the situation at that time

Details of the casualties were not released. Only the owner of the pharmaceutical factory of Hua Fu Hutchison Mining Bureau, the relevant departments of the North China Military Region and the 208th Division, as well as the public security and civil affairs departments know about this matter.

Moreover, the information of the last four departments is relatively general.

Only Hua Fu Hutchison Mining Pharmaceutical Factory has the most detailed data. And the data in the secret letter is very detailed.

Therefore, investigators suspect that the enemy spy obtained information from Heji Mine in Hua Fu.

Investigators found Yu, the boss of Hutchison Mining Pharmaceutical Factory. According to him.

After the explosion,

He once ordered three subordinates to take care of the aftermath. The investigation went unexpectedly smoothly. One of three people

That's Kim, the manager of the production department.

When asked by investigators, he told a story: after the explosion, one of his cousins, Cha Yifeng, visited him.

I went to the unilateral investigation report of the pharmaceutical factory of Hua Fu Hutchison Mining Bureau, which was just sorted out at that time. Cha Yifeng said that he works in a newspaper in Tianjin.

I am going to write an investigation article on this matter.

Need to know some data.

After investigation

Cha Yifeng does live in Tianjin.

But not a reporter.

But a businessman who used to be a reporter.

There is a western medicine wholesale company in Shigu Hutong. What does a businessman want with this investigation report? Doubts about checking other peaks suddenly rose.

With the assistance of Tianjin Public Security Bureau

An invisible net quietly spread out. Cha Yifeng is under 24-hour all-weather monitoring. July 1

The police intercepted a letter sent by Cha Yifeng to Hong Kong.

There is evidence that he is engaged in espionage. When the police consider what action should be taken

A Taiwan Province spy arrested in Shanghai gave up his partner Cha Yifeng in Tianjin. July 3 rd

Cha Yifeng was arrested.

Immediately escorted to Beijing.

There is not much trouble.

Cha Yifeng honestly explained the reason for asking Jin for materials.

It was indeed appointed by a secret order of the secret service of Taiwan Province Province.

These two secret telegrams are just as the experts speculated.

This was concocted by the enemy secret service afterwards. This conclusion was confirmed in 1953. That year

Mao Renfeng, director of the Secrecy Bureau of the Ministry of National Defense of Taiwan Province Province, mentioned this matter in the article.

Calling the move "a joke with the public security organs."

After the "secret telegram case" was solved,

The members of the task force are much more awake.

A new idea is gradually taking shape. ...

1July 5, 950

The second team was withdrawn.

The former task force continued to investigate the case of Hua Fu Hutchison Mining Pharmaceutical Factory. The task force decided to re-examine the scene of the explosion. Three experts who participated in the investigation on July 6th.

You are from the North China Military Region.

One was invited from Shanghai by the Beijing Municipal Public Security Bureau. Three experts investigated two websites that were still closed.

Then I visited some employees in the factory.

A simulation test was also carried out. After careful analysis

The final conclusion is that the explosive explodes first.

Then it triggered the explosion of the detonator packaging point. This conclusion is contrary to that of Matvei Ye Fu, a Soviet expert.

According to this conclusion, the task force adjusted its investigation ideas.

The investigation line of sight shifted to the scene of 1.

When the explosion happened,

There are three workers decorating explosives at the scene.

They were all killed. According to the doorman's records,

The three men had handed in their contraband when they entered the workshop in the morning. such

If one of them causes an explosion,

Most of them are still likely to cause explosive objects. therefore

What exactly did they bring to work that day? This is a problem that investigators need to find out.

Investigators visited the families of three victims. The victim's wife is Liu Gu.

I recalled that my husband was wearing a pair of shoes nailed to his brother-in-law's ass at work that day. The investigator immediately thought of

When the fingernails rub the ground,

Sometimes sparks are generated.

Will it cause an explosion?

If these leather shoes really caused an explosion,

This pair of leather shoes should have disappeared with the owner.

I don't think these shoes were found at the scene. Fortunately, after the explosion,

Public security personnel arrived early.

Blocked the scene in time

After the fire was put out

Put everything together.

Pile up into a hill. at present

Scouts searched the hill. Two days later.

The mountain has been turned over.

The investigator accidentally found a pair of leather shoes with spikes on the soles!

Liu Gu's wife recognized at a glance that this was the shoe worn by her husband on the day of the accident. What's going on here? If this pair of leather shoes belongs to the Liu family,

I'm sure I didn't wear it into the workshop.

Then what shoes did he wear into the workshop that day? Visit again and get to know

Liu Gu found himself wearing the wrong shoes when he entered the factory that day.

I borrowed a pair from a worker who lives nearby. The worker was also seriously injured.

I'm still in the hospital.

Liu Gu's accident was ruled out.

The investigation is continuing. One of the clues caught the attention of investigators. When the victim Fan Zhenguang handed over contraband before entering the workshop that day,

Someone heard the clang of metal in the pocket!

Clash of metal? What would that be? The investigator checked Fan Zhenguang's warehousing registration that day.

The items he handed in were: half a box of matches, a string of five keys and a pack of 14 cigarettes. If you take away what you refuse to hand over, what else will there be? usually

This is a silver dollar.

Did Fan Zhenguang bring silver dollars into the workshop that day? Investigators interviewed more than 100 people again.

I finally learned the truth from an old worker who was seriously injured: the morning of June 14.

He transferred four silver dollars to Fan Zhenguang. He handed Fan Zhenguang the silver dollar.

He was reminded that he must put it in the safe.

Otherwise it may be unsafe to enter the workshop. Fan Zhenguang agreed at that time.

But I didn't expect that he didn't put it in the safe at last.

The task force invited experts again.

Ask them to verify whether the silver dollar will ignite the explosive and cause the explosion. The expert found the silver dollar.

Many simulation experiments have been carried out.

The results show that the silver dollar can really ignite the explosive when it collides. Make a judgment based on these reasons

It is inferred that Fan Zhenguang is operating.

Inadvertently slipped the silver dollar onto the explosive being packed.

Sparks from the collision of silver dollars triggered the explosion.

According to this inference

With the help of the factory, the investigator

Near the scene, three silver coins blown into indistinguishable shapes were found.

The other one is missing.

so far

The task force made a final conclusion on this case: this was a serious explosion accident caused by careless operation.

The members of the task force worked hard for a month and a half.

Although I didn't find the expected "big fish"

However, its fair and meticulous work style and professional and authentic work standards have been rewarded by the party and * * *.
