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

Chapter 445 Research and Judgment Without Results

Ten years of life and death.
In ten years, we can't say that the sea is changing, but it can also be said that the world has changed. In the case of Wumei's disappearance ten years ago, many witnesses' testimonies have been unable to be verified. The second brigade has been busy for two days. A systematic study and judgment is carried out once.

In the past two days, besides running to the remaining three houses, Xu Zheng also went to the place where Wumei disappeared, which were basically parks or riversides. Ten years ago, it was difficult to popularize cameras in these places because there were too many waterways in Changming and there were also many parks.

Including the sycamore trees all over the city, to be honest, they greatly affect the field of view of the camera.

Now the seven members of the second brigade, including the captain, have their own opinions. Since Xu Zheng was inspired by the AI ​​program that automatically generates a Trojan horse the day before yesterday, he has been wondering if the murderer would also use a Trojan horse program to implant Wumei's phone .

It’s just that in the past two days, he also asked the Internet police and the masters of mobile phone maintenance. There was indeed such a Trojan horse ten years ago, but this kind of Trojan horse sent Trojan horse links through text messages and WeChat. Android phones can indeed open it. .

But Wumei's family is superior, and all of them are Apple phones. Trojan horses like the stability of Apple phones can't be downloaded at all.

Therefore, Xu Zheng's current investigation has encountered a bottleneck.

The direction of Lang Shaobai's investigation was that photo. He synthesized the files and found experts in painting, appreciation, and psychology to conduct research and analysis on it. The result came to the conclusion that the photo should be an oil painting hand-painted by the murderer himself.

Although the photo shows the hazy innocence of the first love, these experts judged based on experience that this is all the imagination of the painter. In reality, he should not be recognized by the first love, that is to say, he is just a secret love.

What's more, based on the painting lines and color matching in the photos, it can be proved that the painter is not more than 25 years old, introverted, has psychological problems, and has not studied painting for more than three years. This person is considered talented but not many.

But these are similar to the conclusions drawn from the work of investigating the case back then. The investigators also found clues from this, and searched the entire Changming for people who had studied painting, but they never found the murderer.

This time, Lang Shaobai found a direction that he hadn't looked for before, which was to start with the paint and paper for photo painting, but two days passed, with little success.

Several other people also had their own ideas. Ji Meiyue sorted out the files as usual. She always thought that if she looked through these old files more, there would be surprises. Anyway, these two days passed, and everyone didn't see the surprises.

Wei Yi's thinking is a bit difficult. He has always wanted to prove that Wumei has other relationships with the murderer or the girl who has a crush on the murderer. This point has been investigated by every task force, but they have not been found.

This time Peng Yue and Zhuang Qiang got together, and the two people's investigation ideas are even more novel. They have traveled all over Changming's psychological clinics in the past two days, including the psychological departments of large, medium and small hospitals, but none of them met the conditions or had the time. Too long, the medical records are lost or the doctor can't remember the patient.
The most important thing is that in the past ten years, many psychological clinics have been closed down and banned for a long time. If we want to find out who went to see a psychiatrist in the past, we must work hard.

As for Captain Zhang's investigative thinking, everyone is not very clear. In the past two days, she left early and returned late, and no one knew what she was doing.

Now that the research and judgment had just started, after the report was over, everyone realized that no one had found any clues in the past two days, including Captain Zhang.

This time it was back to before liberation.

Seeing that everyone was a little discouraged, Zhang Yuqi smiled and encouraged everyone, "The leader of this case has given us enough time, and we won't handle other cases, so you don't need to worry at all."

"Yeah, that's where it is." Lang Shaobai took off his glasses, pressed the sore corners of his eyes with his thumb and forefinger, "It's been ten years, and many investigators have failed in this case, so let's investigate now." Two days, what's the rush?"

"Besides." Lang Shaobai pointed to Xu Zheng, "We still have Xiaozheng, you don't need to believe in yourself, but you must absolutely trust Detective Xu."

Xu Zhengzheng was looking at the electric car case that went to Director Nie's office to report to the Liulihe Police Station yesterday, and took an unopened thermos cup from Director Nie. There was no inscription or logo on the cup, and it felt very good. It looked like it was specially made. thing.

After hearing Lang Shaobai's praise, Xu Zheng smiled wryly, "Brother Lang, you've dug a hole for me, but this time I won't dance. I've been just as confused as you these days."

Regardless of Xu Zheng's excuses, he started to make noises, and Peng Yue was the most active, "Come on, come on, this time I'm in the dealership, let's bet, Xu Zheng can find the clues in a few days, and catch the real culprit in the next few days."

Zhuang Qiang was not far behind, "Then one person guessed right, are you going to treat someone to dinner?"

Ji Meiyue continued quietly: "I seem to remember that Peng Yue already owes us three meals."

Who knew that Wei Yi next to him said abruptly: "Four times, I remember it very clearly."

"Can you still have a pleasant chat, thinking about deducting the [-] cents in my pocket all day long, can this work, the previous cancellation, this time, if I still lose, how about just treating me directly?" Peng Yue used again He came up with his dragging formula.

Anyway, his dinner treat will be next time.

Everyone laughed happily for a while, Xu Zheng coughed and interrupted the fun, "Based on the current information, we don't even have any information about the murderer. As for the murderer's profile, there are several versions, but these are not helpful for solving the case." What substantial help.

Moreover, the murderer is alive or dead now. He kidnapped these five beauties ten years ago. Why did he stop?Are the five women still alive?
Were they imprisoned in a hidden place, or were they directly killed?
Our police can't find them either. "

Zhuang Qiang was speechless, "Zheng'er, if according to what you said, the five women were imprisoned in a hidden place by the murderer, like in European and American movies, the murderer must be rich, and he must be very rich, or else just buy medicine or It costs a lot of money to buy condoms and things that invigorate the kidney and strengthen the yang.”

Peng Yue nodded and added to him: "There are also contraceptives. Before Wumei disappeared, two of them had children."

"Did the two of you make a mistake?" Xu Zheng raised his forehead, "I just made a hypothesis. In Changming, tell me where to find such a hidden place, and the murderer must be rich and over 20 years old. Aged, living alone."

"Xiaozheng, if not all five women survived, what about only two women?" Lang Shaobai crossed his hands, narrowed his eyes slightly and said in thought: "Maybe two women are alive, or at least one woman is alive. This is the reason why he did not continue to commit crimes."

Ji Meiyue frowned, "Squadron Lang, what do you mean, there is a woman who made the murderer fall in love with her? It's been ten years. What kind of love is being with the murderer after ten years of imprisonment?"

Lang Shaobai was also full of distress, "At present, our police have too few clues. We have just deduced these according to the thinking of men. In fact, whether the murderer is male or female, old or young, it is not certain, but it is certain. The murderer was mentally ill."

Seeing everyone scrambling to discuss, Zhang Yuqi also said at this time: "I have been conducting investigations for the past two days, and the direction of my investigation is to believe that the murderer is a woman, and she is a T, a psychopath, who loves Wumei's appearance. Why did the murderer stop later, I can't figure it out."

When everyone heard that Zhang Yuqi's investigation direction was so weird, their expressions became weird. Zhuang Qiang raised his eyebrows at Peng Yue, and Peng Yue shook his head slightly
"Brother, what is T?" In the weird atmosphere, Li Wanwan, who knew nothing, asked Xu Zheng in a low voice, but the research room is not big, and the voice is so small that everyone can hear it.

"Haha." Everyone laughed, even Zhang Yuqi smiled and shook her head.

I have encountered all kinds of strange things in criminal investigation and handling cases. This is drizzle for everyone. Just now I just felt that the captain did not take the usual path.

Zhuang Qiang squinted his eyes and said with a smile: "Come to brother Wanwan, I'll give you a good idea of ​​what a T is."

Ji Meiyue rolled her eyes at him, pulled Li Wanwan over and explained to her in a low voice.

Zhang Yuqi saw nothing new in the research and judgment, and directly announced, "Let's get off work first, and you all think about it when you go back. If you are the murderer, how did you choose to abduct these five women without being caught by the police."

Seeing that the first trial and judgment of this case ended in such a hasty way, Xu Zheng just sighed in his heart. The case is not easy to handle. Generally speaking, the police resources for restarting old cases are greater than those for new cases. Lines will receive effective feedback and support.

But the premise is that the Second Brigade must be able to find a fruitful investigation direction.

Now, two days of trial and error have passed, and the next step is to investigate in groups.

When it was time to get off work, Xu Zheng did not go home, but drove to the provincial office, and picked up his classmate lawyer Xiao Dingyi at the gate of the provincial office. Today, he has signed an appointment with the logistics equipment department of the Ministry of Public Security.

Because they are all inside the police, the signing place was arranged by Xu Zheng's teacher, Professor Ji Dongli, and became his work place.

"Xiaozheng, let me tell you the truth. You asked me to help you look at these contracts that may be tens of millions. I don't feel at ease. I'm always afraid that your business will be ruined." Xiao Dingyi is also a freshman at work. Boy, he is about the same as Xu Zheng, and he has just become a regular for about a year.

Xu Zheng comforted him, "Don't worry, as long as there are no big traps in the contract, it is not illegal, and there are huge liquidated damages, it will not be a problem. Besides, this is my teacher, Professor Ji, who led the way, and it is the Ministry of Public Security." Yes, there will definitely not be those messy things."

"That's what you said." Xiao Dingyi forced a smile, his face relaxed a little.

Soon, in Professor Ji Dongli's office, the two parties met each other. Professor Ji introduced them to each other, and after a few words of courtesy, the leading man wearing glasses said, "Comrade Xu, we will catch up soon." Let’s make a long story short for this flight at the latest, this little brother should be the lawyer you hired, so let him have a look at the contract details first?”

Xu Zheng hurriedly agreed, Xiao Dingyi took the contract and watched it carefully, the man with glasses said again: "I just told your teacher about the contents of our contract, so let me briefly explain it to you now."

Professor Ji stopped him, "Commissioner Kang doesn't need to be so troublesome." He turned to look at Xu Zheng, "The content of the contract is probably what you discussed before, this time it's just on paper, since Commissioner Kang and the others are in a hurry Airplane, you just sign the contract.”

Now that Professor Ji said so, Xu Zheng nodded quickly. Soon, he signed several documents and left his identity information and bank card number. Because it was a written contract, Commissioner Kang waited for him to sign, and then Passed it back and stamped it, which means the contract was successfully signed.

The successful signing of these two contracts not only means that Xu Zheng's invention can make a profit for him, but also means that he cooperates with the Ministry of Public Security. This alone can let the big bosses in the Ministry know about him.

After sending Commissioner Kang and his party away, Ji Dongli teased Xu Zheng with a smile, "Boy, be happy, maybe just these two things will make you a million dollars a year."

"How can the teacher have so many?" Xu Zheng thought he was joking, "The use of these two things is very limited, and the amount of use is also small. Even if they are provided to police units at all levels across the country, there will not be much money. .”

Ji Dongli knew that Xu Zheng didn't believe him, "Go, I'll take you to do an experiment."

He just stood up and looked at Xu Zheng's classmates, "Young man, I won't take you this time. We have to go to the laboratory. Can you stay in my office and drink tea?"

How could Xiao Dingyi dare to stay here and see that it was the office of a big boss. In case of any omission, he couldn't explain it clearly, so he quickly bid farewell, but Xu Zheng didn't keep him. Anyway, the provincial office is difficult to enter and exit. No one will stop him when he goes out.

After seeing off Xiao Dingyi, Ji Dongli took Xu Zheng to learn about the planing studio. At this time, there were two workbenches busy inside.

To be honest from the bottom of my heart, Xu Zheng still can't accept dissecting a corpse by himself. It's not the same as a skull, it's a bone. What is this? He looked at the workbench.
That's all, I can't watch it, it will affect my appetite for dinner if I watch too much.

Ji Dongli didn't delay when he came here, pointing to a very clean ground, "There was a piece of blood dripping here in the afternoon, and now it has been wiped clean with water, now let's use the skull blood contrast agent you found to see if it is there other effects."

After speaking, he took out a contrast agent from his pocket and sprayed it evenly on the floor tiles. After he sprayed for the second time, a scar different from the light blue color of the contrast agent suddenly appeared on the clean floor tiles just now.

"See, with such a contrast agent, even if the murderer cleans the blood at the crime scene, we can easily find clues, unless he uses other means to destroy the scene, such as gasoline, fire, soaking in water and other abnormal means. "Professor Ji said confidently.

Xu Zheng couldn't be clear when he saw this. This contrast agent should be improved by Professor Ji. Its previous function was only to visualize the blood flow of the skull. "Teacher, thank you for your hard work."

Ji Dongli laughed, "Let's go, get off work early today, go to my house for dinner, by the way, call your girlfriend, your teacher has read it a few times."
