I don't want to solve the case when I'm a little policeman.

Chapter 914 The secret behind it

Half an hour later, as soon as Xu Zheng changed his clothes and came downstairs, Han Dongwen and his wife informed Xu Xiuchuan of what was going on there. He didn't even have time to eat lunch, so he hurried to Hitotsubashi District Taikang Hospital.

As soon as I arrived at the door of the ward, I saw many police officers from the Hitotsubashi District Bureau, wearing police uniforms, forming small circles and discussing something.

Xu Zheng walked over quickly and saw a few familiar former colleagues in the crowd. He was about to go over and say hello. What he didn't expect was that these people who had been very enthusiastic towards him in the past actually pretended not to see him this time. he.

This scene made his heart skip a beat. He didn't have time to analyze why those people had such an attitude, because his grandma Su Tongyun just walked out.

Seeing Xu Zheng coming, the old man turned his head slightly and waved his hand to prevent him from visiting Aunt Bai in the ward, "Come here, I will tell you something."

Grandma and grandson walked aside. Grandma Su Tongyun sighed without saying anything, with a sad look on her face, "Did you see the expressions of those people at the door of the ward just now?

Sigh...don't take it seriously, your Aunt Bai's condition may really have something to do with us..."

It turns out that the reason Aunt Bai got the tumor this time was that their home contained a radioactive gas - radon.

In ordinary family life, decoration materials, such as feldspar, granite and other natural stones containing radioactive elements, easily release radon gas.

When radon gas is evenly distributed indoors, it decays to produce alpha particles and produce progeny with shorter half-lives.

These daughter bodies can attach to aerosols in indoor air to form radioactive aerosols, which may enter the body as people breathe and be deposited in the respiratory system.

Living in an environment with high concentrations of radon gas for a long time may increase the risk of lung cancer.

If there are still people smoking at home, secondhand smoke will increase the harm of radon gas to the human body.

This morning, the laboratory team tested all the decoration stones in Xu Xiuchuan's home, and finally found the source of radon gas in several orchid pots and soil.

Among them were two pots of orchids, the material of which was made of moonstone from feldspar, and these two pots of orchids happened to be given to Aunt Bai by grandma Su Yuntong.

So far, although the source of the radon gas that caused Aunt Bai's illness has not been detected, the two pots of orchids given to her by Xu Zheng's family are suspected.

Moonstone is very precious. It is a feldspar mineral with moonlight effect composed of a mixture of two feldspars. It is almost not produced in China, or the production is extremely low, and most of them are imported.

If all the flowerpots were made of moonstone, it would cost at least hundreds of thousands or millions.

Most of the items circulating on the market are moonstone bracelets.

Of course, the two suspected flower pots of Xu Zheng's family cannot all be made of moonstone. They are just inlaid with a circle around the mouth of the pot.

In fact, there is no authoritative organization that has determined whether radioactive nitrogen is used in moonstone and whether it can cause cancer. Even if there is, the public will think that the organization serves capital.

But many people still think that moonstone bracelets contain radiation.

Xu Zheng remembered that he had checked this information before. Moonstone and marble are both naturally occurring minerals and contain trace amounts of carcinogenic molecules, but they are far below the national standards.

In other words, long-term wearing will not cause lung cancer.

After learning the truth from his grandma, Xu Zheng finally understood why the people at the door didn't want to talk to him. They were probably worried that there was something wrong with the two flower pots that his grandma gave to Aunt Bai.

As for these two pots of orchids, Xu Zheng remembered that their home was renovated two years ago. Grandma's small garden and Han Rui's yard were knocked down and rebuilt into a large yard.

Because they all want to give the children a large space to play, they no longer plant flowers and plants, but plant everything with turf.

So grandma gave away the flowers and plants she had cultivated for many years.

I didn't expect that something like this would happen this time.

"Grandma, I remember that the orchids you raised were all phalaenopsis. They should be about ten years old. Don't worry, if it really caused cancer, our grandparents and grandchildren would be dead long ago."

Listening to Xu Zheng's comforting words, grandma Su Tongyun was still sad, "I'm not worried that it's us, but I'm worried that your Aunt Bai's disease is late-stage lung cancer."

"Ji people have their own destiny. Uncle Xu has been an honest official throughout his life, worthy of the people and the police uniform. Aunt Bai and the others will definitely love each other until they grow old."

While the two were talking, Xu Xiuchuan walked out of the ward. He looked up and saw Xu Zheng. He stretched out his hand and said, "Xiao Zheng is here. Your aunt just talked about you. Come in quickly."

Xu Zheng saw that Xu Xiuchuan's expression was relaxed and his face was no longer sad. It was obvious that he had good news. He did not enter the ward directly, but asked at the door: "Uncle, have the results of aunt's biopsy come out?"

Xu Xiuchuan is an old man. When he saw the situation at the scene, he instantly judged it. He hurriedly explained: "It's out, it's out. It's non-small cell cancer. Fortunately, it's not in the late stage.

The doctor said that it is probably in the second stage now, but the cancer cells are larger, and it is still very hopeful to be cured. "

Xu Zheng felt relieved when he heard that Aunt Bai was not in danger for the time being. Aunt Bai had always been kind to him and was an elder he respected very much.

But he was still worried because Xu Xiuchuan didn't mention the issue of radioactive sources just now.

Maybe the results from the testing unit haven't come out yet.

Xu Zheng entered the ward, but Xu Xiuchuan did not follow him in. Instead, he took out his mobile phone and made several calls in succession. While talking, the expression on his face changed in various ways, and his eyes suddenly turned cold.
In the ward, Aunt Bai, who was lying on the bed, had a gloomy face and a languid expression. When she saw Xu Zheng and Su Tongyun coming in, she forced herself to smile, "Xiao Zheng is back?

Seeing that it was really not the right time for me to be ill, I even asked our child to make a special trip. "

Xu Zheng hurriedly stepped forward and took her hand, "Aunt Bai, what are you talking about? No matter how busy I am, I have to come back to see you. Sister Xiaorui was originally going to come with me. I asked her to come back to see you in the afternoon. ”

Aunt Bai understands that the police are currently investigating the real cause of her illness. She has never doubted Xu Zheng's family, but due to business matters, she, the client, cannot make any suggestions casually.

"Oh, look what happened. Xiaozheng, don't take it to heart. Auntie and your uncle have always treated you as their own child."

Grandma Su Tongyun took over, "Let's close the door and speak our own language. If Yuru, your illness is caused by man-made factors, Xiao Zheng will come back and ask him to handle the case.

I would like to see who is so bold and dares to frame the family members of police officers. "

Aunt Bai forced a smile and shook her head slightly, "Xiao Zheng handles major cases and is very busy. I can't trouble him with this little thing, so I asked him to sit with me for a while and talk. It's better than anything else.

In the blink of an eye, all the little clay monkeys back then were married and had children.

Xiaozheng, you have to hurry up and have a second child.

The same goes for Xiaorui. You can take leave from work. You can take a leave of absence for a year and a half, and then you can go back to work after giving birth to your second child. "

Xu Zheng couldn't accept this. The expectations of the elders were like a huge mountain. If he interceded for Sister Xiaorui, he would tell Sister Xiaorui face to face about the subsequent birth.

He could only change the subject first, "Brother Junqi and Manman haven't come back yet?"

When Aunt Bai heard Xu Zheng mention her two children, she snorted, "Don't mention them. I didn't tell them about my illness this time, and you don't tell them either. What can they do when they come back?"
Besides pissing me off! "

Every family has its own problems. Xu Junqi is two years older than Xu Zheng. Now let alone getting married, he doesn't even have a girlfriend. When they talk about him, Xu Xiuchuan and his wife both sigh and shake their heads.

Especially Xu Zheng, a role model who got married at the age of 24 and had children at the age of 25, Xu Junqi is not favored by his parents.

In this regard, Xu Zheng and his grandmother Su Tongyun could only advise and make excuses for Xu Junqi and his sister.

After a while, Xu Xiuchuan came back and called Xu Zheng out, "Xiao Zheng, how long will it take at the earliest for the Guohe Fugitive Office to bring someone back from abroad?"

It turns out that the test results from the laboratory department just came out.

The real source of radiation was not the two pots of orchids that Xu Zheng's grandma gave to Aunt Bai, but a pot of golden sand chrysanthemum that Aunt Bai bought at the orchid trading place a year ago.

There is no problem with the orchid or the pot, but the soil contains high concentrations of radon mineral debris.

According to professional analysis, radioactive sources are one of the conditions that cause lung cancer, but second-hand smoke is also an important cause. Therefore, Xu Xiuchuan now extremely regrets that he did not insist on quitting smoking.

But this is not a time to think about quitting smoking.

It is the source of the pot of golden sand tree chrysanthemum.

According to the case handling procedures, causing someone to become seriously ill is a criminal offence. The Hitotsubashi District Criminal Police Brigade took over the case. Under the existing conditions, they quickly tracked down the businessman who sold Aunt Bai the orchids a year ago.

I also investigated the origin of the orchid soil from a businessman.
Although the real murderer has not been found so far, the investigation revealed that there were 13 orchids in the same batch a year ago, and they were all sold on the day Aunt Bai bought them.

People from the criminal police brigade are now contacting those buyers.

The reason why Xu Xiuchuan came to Xu Zheng was because the salesperson who sold orchids last year applied to immigrate abroad after last year's flower show, and this person was the most suspicious.

There are many ways to bring criminal suspects or criminals back from abroad through official channels. Generally, they follow the procedures of Interpol, but the time is very slow and involve various negotiations and transactions.

If the "Red Notice" channel is used, then domestic police officers are sent on business trips abroad to proactively persuade them to return, or they use anti-corruption channels negotiated by the two countries' foreign affairs agencies.

There are also ways to smuggle people into the country without going through official channels.
Now Xu Xiuchuan is asking about the "Red Notice" and wants to catch the criminal suspect as soon as possible. Xu Zheng has no specific contact with this aspect, "Uncle, if you are just a salesperson, the Guohe Fugitive Office will definitely not agree to help.

However, I can ask friends from relevant departments for help. As long as we can determine the location of that person and bring him back, it will only take three to five days. "

"This" Xu Xiuchuan hesitated. He could ask his superiors for help and contact the Guohe Escape Office, but he didn't want Xu Zheng to come forward to help because he was worried that it would affect his career.

Xu Zhengneng could guess what Xu Xiuchuan was thinking and wanted to explain that he was no longer what he used to be. However, due to the occasion, he changed the subject and asked, "Uncle, which country did that salesman go to?"

"Toyang!" Xu Xiuchuan gritted his teeth, "The year before last...well...how should I put it, Xiaozheng, you still remember the year before last, when a Japanese man and three losers went to your house in the middle of the night to ambush you, right?

Afterwards, we found out about this group’s accomplices in Changming, during which time there was a couple in my jurisdiction.

At that time, I was the executive deputy of the branch and the first person responsible for arresting them. At that time, someone passed a message to me and asked me to clear the way for them to escape Changming.

Counting the time now, it was after I finished my errands that I started to set up a trap for you, Aunt Bai.

It's all my fault. I remember people threatening me, but I didn't pay attention at all. "

Xu Zheng almost cursed when he heard this. He thought that whatever happened to Aunt Bai's illness had something to do with him, but then he thought about it. Regardless of whether it was related or not, he needed to find out the truth, both publicly and privately.

However, he still comforted Xu Xiuchuan, "It's still too early to draw conclusions. Maybe the real target of the murderer is not Aunt Bai, but one of the other 12 people."

Xu Xiuchuan nodded and subconsciously took out a box of cigarettes. Just as he was about to take out one, he thought of his wife in the ward and clutched the cigarette box tightly. "I have asked my colleagues to investigate the other 12 people who bought the same batch of orchids.

The results are expected to come out in the afternoon. "

Xu Zheng originally planned to take the high-speed train back to the capital tomorrow morning, and the tickets were all booked, but now he didn't talk about it, mentally preparing to wait until the case was revealed.

In fact, he was very curious now. Could it be that the murderer behind the scenes just wanted to use a pot of highly radioactive orchids to take revenge on Xu Xiuchuan or Aunt Bai?

Or the other 12 flower buyers?

Doesn't the murderer have other intentions?

And did Xu Xiuchuan hide anything else from him?
The more Xu Zheng thought about it, the more he felt that there must be another mystery behind it, but before he could ask for details, a group of people walked in the corridor of the hospital, all of whom were senior officials of the Changming Municipal Bureau.

They are also his old bosses.

When everyone met, they exchanged greetings and greetings. Li Wanwan followed behind, holding flowers in her left hand and a fruit plate in her right hand. At first glance, she looked like she was running errands.

But the fact that she can follow the leader here also represents her elders.

The leaders entered the ward to visit the patients. Li Wanwan went in and put down the flowers and fruit plate, chatted with Aunt Bai for a few words, then withdrew again, ignoring the greetings of other people in the corridor, and walked to Xu Zheng alone.

"Senior brother, you didn't tell us when you came back."

Xu Zheng did not follow Wan Haihong and others into the ward. The inside was too small and there was no room to stand even if they squeezed in. However, he felt awkward staying outside.

The people at Hitotsubashi District Bureau who didn't want to say hello to him just now, now know the reason for Aunt Bai's illness, and they all become enthusiastic, as if the previous unpleasantness has not happened.

In this regard, he could only patiently chat with them for a few words, and just then Li Wanwan came out and rescued him from the embarrassment and helplessness.

"I came back in the morning. I only plan to stay at home for one day this time. What are you telling me to do? Are you not busy?"

How could the criminal police not be busy? Li Wanwan put his head on his forehead and sighed, "We haven't had a day off since the Chinese New Year. Brother, do you have any plans to come to Pingjiang Province in the near future from your homicide backlog office?
Hehe, I want to apply to join the task force in advance. "

The wealth should not go to outsiders, Xu Zheng is not a person of high moral standards, he nodded and agreed: "Don't worry, as long as we plan to solve the backlog of murder cases in Pingjiang Province over the years.

I will definitely agree to let you join the task force. "

Satisfied with the affirmative answer, Li Wanwan tilted her head and suggested: "Brother, how about we handle the Changming University corpse dismemberment case first?"

Xu Zheng was stunned when he heard this, and immediately didn't want to talk to her. It was true that the case was not much less difficult than Aunt Mei's case.

Even because the murderer's method of committing the crime was clean and simple, Xu Zheng would never reopen the case without new evidence.

Unless the system can help!
