Chapter 604 Abnormal Woman

The Jingcheng case is more difficult than the Jiangcheng case.

The big point is that no new cases have emerged in the Jingcheng case, and the investigation coverage has reached 99%, making it difficult to find a breakthrough.

However, Chen Yi already had a rough profile of the murderer and needed clues to fill in the clarity.

A father seeking revenge for his daughter.

Combined with the personalities of the three victims and human nature, this is currently the greatest possibility.

The next afternoon, in less than a day, the information had been retrieved. The operation was very simple. In the era of electronic information, computers can be used to supplement student status information and then screen based on keywords.

Student status is basic citizen information, bound to the ID card, and is public information to the police.

The victim Qiao Rui has tens of thousands of alumni among the 65,000 patients, including primary school alumni, middle school alumni and university alumni. Excluding those over thirty-one and under nineteen, there are still 4,000 people left.

Of the 4,000 people, 3,000 are women.

Most of them are primary schools and middle schools, and there are only eight alumni from universities, because Qiao Rui went to university elsewhere.

Of the eight, five were women.

The proportion of patients with depression, including mild depression and men, is about 3%, 120 people.

Three percent, which is not a low proportion, does not include those who did not come to see a doctor or those who went to well-known hospitals in other places. This shows that the lives of a considerable number of young people are not that good.

In six years, Xiang Shu treated a total of 90 young women with depression according to their age, gender and school.

After getting the data, Chen Yi immediately issued an order: "Coordinate 18 investigators, two in a group, each group is responsible for ten people, to visit and inquire in person, and be sure to see the person to make sure the person is still alive. "

Chai Ziyi: "Don't worry Chen Xun, nothing will go wrong. I'll make arrangements first."

After Chai Ziyi left the temporary office of the special case team, Chen Yi focused on the remaining 3,900 people.

Again, depression is just speculation. If A exists, it is unknown whether she is depressed. She may have other diseases.

"Taken together, A is definitely a woman...but the man cannot be ignored."

Chen Yi touched his chin. It felt obviously frosted. He forgot to shave in the morning.

"Should we contact him by phone again, or deploy police forces to conduct a comprehensive visit?"

With 3,900 people, it would take 390 days to meet ten people in one day. This time can be shortened by the number of police. If there are 7,000 police, theoretically they can all meet in one day.

Even if you go out of town, you can still ask the local police to assist in the investigation.

But does A really exist? Is she really on Xiang Shu's patient list?

While thinking, Chai Ziyi returned and the order had been issued. The ninety people would complete the interview within a few days. The purpose of the interview was to determine whether the person who answered the phone was actually him.

This is the second blind spot in this case that is not an investigation blind spot. Chai Ziyi had already done a good job back then. He called more than 60,000 people one by one to find hidden medical malpractice. He was very decisive.

"Chen Xun, I have a question." Chai Ziyi said.

Chen Yi swiped the computer at random to scan the list: "Say."

Chai Ziyi: "If all ninety patients with depression are alive, it seems that the suspicion cannot be ruled out? Because there may be depression murderers but the murderer did not commit suicide. I checked the records and there was no young woman who died abnormally."

Chen Yi turned around: "Chai Zhi thinks the murderer might be a woman?"

Chai Ziyi: "Of course a man is most likely, but..."

Chen Yi: "I understand what Chai Zhi means. A woman killed three adult men in a row, and she still used hanging method. It's a bit difficult, but it can be done in theory, but every step we take now is It might be wrong. It's just a process of trial and error, so don't think too much about it for now.

To borrow a sentence: make bold assumptions and verify carefully. "

It is impossible for the investigators to think exactly the same. Chen Yi would not impose his own judgment on Chai Ziyi. The other party was also worried that it would be in vain. After all, after so many years of investigation, he had a mentality of worrying about gains and losses.

But the probability that the murderer is a woman is very low for him.

It could even be said that he was certain that the murderer must be a man.

As the leader of the special case team, Chen Yi has the right to decide the direction of the investigation, but this sentence cannot be clearly stated. Chai Ziyi is quite willing to make friends.

"Understood." Chai Ziyi nodded and asked: "What should we do with the remaining 3,900 people? Make a phone call or visit in person?"

Chen Yi: "How long does it take to conduct a face-to-face visit?"

Chai Ziyi thought for a long time and replied: "Deploy police forces from various branches and police stations to cooperate. Counting the auxiliary police, on the premise of ensuring normal public security in the city... there are still five to six hundred people."

It is normal to coordinate 600 people to investigate major serial murder cases. If it is not enough, they can continue to be drawn from other cities.

In the 1980s, in order to investigate a heinous shooting case, Imperial City mobilized 30,000 police officers across the country. It took seven months to detect the case, and they also conducted a blanket search when making the arrest.

The more serious the case, the higher the priority. In contrast, it is impossible for the police to dispatch a large number of police forces to help find someone just because his mobile phone or electric car is stolen.

Chen Yi weighed for three seconds and finalized: "We will wait for the results of the interviews with the ninety people. If there is no harvest, we will start a comprehensive interview and everyone will see it.

This time, we will use the human wave tactic. If the police force is not enough, we will send investigation letters to surrounding cities in the name of the special case team. "

Chai Ziyi accepted the order: "Yes!"

…

The time came three days later.

The results of interviews with ninety people have come out. There is nothing abnormal. They are all alive and well, and no one said they knew Qiao Rui.

At that moment, Chai Ziyi immediately notified all police stations and sub-bureaus in Jingcheng and mobilized a total of 580 people in one day to prepare for a comprehensive visit to 3,900 patients.

Work in pairs to make sure no one is missed.

If you have moved out of town and drive to a nearby city, or ask the local police to assist in the investigation of a distant city, you must meet face to face and ask in detail whether you know Zhang Wenyang and Qiao Rui.

Before the mission was carried out, Chai Ziyi issued a written document to all investigators: the interview subjects may lie, so each person must be observed carefully, and subtle changes in expressions and tone must be captured, and records must be kept.

The main purpose is to remind the police at the police station that they lack experience in investigating serious cases and are prone to making mistakes.

During this period, He Xin and others successively reported real-time investigation results.

The first is Xiang Shu.

Doctor Xiang Shu has good medical ethics, and there are no mistakes in the records in the file. Almost all colleagues and patients have positive comments about Xiang Shu, and the remaining few negative comments are highly subjective.

No matter how perfect it is, there is no guarantee that everyone will like it, unless it is a hundred dollar bill.

In terms of business, Xiang Shu worked very hard. After joining the Economic Development District Hospital, it took him five years to be promoted from attending physician to deputy chief physician. He has a bright future.

If there are certain medical research results in the future, he will become one of the few chief physicians in the Economic Development Zone.

In addition to these, Shixin also investigated whether Xiang Shu had misdiagnosed during his work, which caused adverse consequences and there was no record.

The probability of misdiagnosis is very low. With the current medical level, as long as doctors perform their duties, it is almost impossible.

In a simple sentence: I may not be able to cure you, and I may not know what disease you have, but as long as I draw a conclusion, I will never make a wrong diagnosis.

In this matter, the doctor is still very cautious.

And if you don’t understand, you can ask your seniors.

Some people who are unable to get the appointment as director will choose to get the appointment of a very young attending physician, because young attending physicians have little experience and dare not talk nonsense if they encounter complex conditions, and then take the initiative to ask the seniors in the hospital.

If you register a director number, a director will treat you.

You sign up for an attending number, and if you are lucky, several directors may come to see you, which is equivalent to an outpatient consultation.

Therefore, the motive for Xiang Shu’s death due to misdiagnosis can be ruled out.

"Oh, what a pity."

Shi Xin lamented Xiang Shu's death, which was a loss to the Economic Development District Hospital and a loss to the nation's medical industry.

It seems that in the hospital, he heard a lot about Xiang Shu and was inspired by it.

Zhang Wenyang's interpersonal relationships are a little complicated. As a dance teacher, he will know people from all walks of life. Everyone's evaluation of Zhang Wenyang is pretty good. Although it is not as rave reviews as Xiang Shu, at least no one scolds him for something.

To Chen Yi's surprise, Teng Dabin and Su Ying found something that was not in the file. Sure enough, the combination of men and women had miraculous effects, but it was of little use temporarily.

"Zhang Wenyang has the qualification to recommend a quota for the Peach Blossom Award Dance Competition. Not many people know about this matter. You must ask specifically and to the right person before you can find out." Su Ying reported.

Teng Dabin affirmed Su Ying's investigative ability: "Su Ying has some skills in forensic medicine. He said that in addition to love killings, in other cases of murders with clear targets and the victims are men, tracing the source must be inseparable from interests.

So, she wanted to find out whether a professional dance teacher had certain social resources.

The money is definitely out of the question, the man surnamed Chai has already found out clearly. "

"Call Chai Zhi or Captain Chai! Put away your charlatanism!" Chen Yi reminded, as if across a mountain, he had never heard of this competition: "Peach Blossom Award?"

Su Ying explained: "The Peach Blossom Award is one of the top competitions in the domestic dance industry. There is a threshold for registration. I have asked several girls who are studying dance. They all have the dream of participating in the Peach Blossom Award competition. Even if they are just accompanying runners, they can win Certain popularity.

Zhang Wenyang has connections who can recommend places for the competition. As long as the recommendation is made, the competition can be predetermined. I don’t know if he has recommended it over the years. You need to check within the competition committee. "

Hearing this, Qin Fei said: "Sister Su, will this clue help the case?"

Su Ying: "I don't know, it doesn't hurt to have one more clue. Let me tell you a possibility: someone asked Zhang Wenyang to recommend him to participate in the competition, but Zhang Wenyang didn't agree, and the other party killed him out of spite."

Qin Fei felt it was a bit ridiculous.

But Chen Yi smiled and said: "It's a good guess. Reality doesn't follow logic. Even psychiatrists can't understand the reasons why some madmen kill.

Let me add based on what you said, a girl wanted to participate in the competition and Zhang Wenyang refused, so she couldn't think of hanging herself. The father blamed Zhang Wenyang for his daughter's death and ended Zhang Wenyang's life by hanging. "

Su Ying nodded: "Chen Xun's statement is more reliable. How is the investigation at Qiao Rui's side?"

Chen Yidao: "We are still investigating, and the scope has been expanded to include all his alumni during his schooling. When it comes to interpersonal relationships, Qiao Rui is the easiest among the three, and he is also the youngest. It is relatively easy to investigate and find abnormalities, so he is Investigation focus."

Su Ying was a little surprised: "How many people are there?"

Chen Yi: "There is more than one victim. We need to find points of overlap. Xiang Shu's patients are the basis for selection. There are not many, maybe three thousand people."

The investigation of this case adheres to the principle of easy things first and difficult ones later. If there are no abnormalities in the patients and alumni, Chen Yi must carefully consider how to move forward with the case, and even be prepared for the special case team to return without success.

Teng Dabin: "I asked why there are so few people in the detachment today, I even sent them out to visit.

Chen Yi, how sure are you about this case? "

Chen Yi habitually took out his cigarette case and said with a smile: "It's not me, it's us. How sure are we? Confidence is necessary for this old case with no clues. Since you asked, let's be 100% confident. "

Teng Dabin grinned: "It sounds like bragging, but when it comes out of your mouth, I don't mean to despise you at all."

Chen Yi lit a cigarette and said: "The police have a numerical advantage. As long as they find the connection between the three victims, no matter how outrageous the connection is, they can get to the truth of the case. Do you understand me?"

Teng Dabin was slightly serious: "Understand, investigating the case is not the work of one person, it requires the joint efforts of everyone.

Then get busy. Su Ying and I are leaving first. We have to continue digging about Zhang Wenyang. I gradually began to like this feeling of decryption. "

After working undercover abroad for many years, he was exposed to new things.

…

Another few days passed.

With the intervention of hundreds of police officers, the interview work went very smoothly. Each group of investigators only needed to be responsible for thirteen people. Today, there was finally an abnormal situation.

Chai Ziyi placed a person's information in front of Chen Yi.

The name is Ge Shuiyun, female, 34 years old, local.

Thirty-four is his current age. He was 26 when the crime occurred eight years ago. He attended a middle school in the Economic Development Zone in high school. He was an alumnus of the victim Qiao Rui and was in the same school but in a different class.

When I registered at the Neurology Department of Kaikai District Hospital, I was 25 years old and had symptoms of neuralgia and numbness in my limbs. The medical records showed that there were no major problems for the time being. I returned for a follow-up visit three days later, but the patient did not come for a follow-up visit.

I don’t know if I have learned to dance. I just got the information and haven’t started investigating yet.

The unusual thing about this girl is that she cannot be contacted. The mobile phone number in her personal information has been changed a long time ago, and there is no current number under her ID card.

"Chen Xun, not only can we not contact Ge Shuiyun, but his ID card has also been silent for nine years. Have we found the right person?"

Chai Ziyi sat down and spoke.

"Nine years." Chen Yi picked up the information, stared at Ge Shuiyun's name for a long time, and said, "Ge Shuiyun? If the name is reversed..."

As soon as Chai Ziyi came to his senses, his eyes suddenly became solemn: "Yunshui Inn?"

Chen Yi: "Dig deeper and get her detailed information."

Chai Ziyi stood up quickly: "Okay, I'll go right away."
