All three doctors are not too old, they are all in their thirties. The height and body shape are also similar, and the face shape is a public number. It seems that everyone can substitute those two photos. So there is no difference just in appearance. The serious crime team considered that it did not want to startle the snake and find out the real murderer. So a few old men got a fake ID card and hung up the numbers of the three doctors, planning to find a way to obtain the DNA samples of the three doctors for testing when they registered.

However, the three of them expressed surprise at the arrival of several men. Jiang Chonglang said calmly: "Doctor, it's like this." This time, we came with a patient on our back, and she was embarrassed to come. You can answer our questions with confidence. The three doctors were all dazed, but nodded awkwardly. So a few people asked the three people three times in a row according to some gynecological knowledge that Zhang Lanshan gave them last night. Then, he took out his mobile phone and said to the three doctors: "This is the patient's WeChat account, and she will add our hospital's WeChat account when the time comes, or you can add it too." ”

WeChat's avatar is Yang Qianting's photo before her death. In this regard, the three doctors showed mixed results. Dr. Ye Yasen was surprised and said: "I have seen this woman, wasn't she pregnant not long ago, how can she have it again, she is so strong." Okay, I'll contact her and I'll schedule the surgery as soon as possible. However, everyone could see a little panic and nervousness in his eyes; Doctor Nie En also recognized Yang Qianting, and said with a little disdain: "It's this woman again, I've seen it, okay." When to come. But I don't use WeChat much, let him come by himself, I won't take the initiative to contact him. Jiang Chonglang asked, "What, you know her, can you tell us about it?" "I'm sorry, but as a doctor, I have an obligation to keep my patients' privacy confidential. However, before leaving, several people heard Dr. Nie En muttering in a low voice through the crack in the door: "Sure enough, Sister Yao will always be Sister Yao, and the dog can't change ****." ”； Dr. Chen Yuzhi doesn't seem to have a good memory, and he doesn't seem to remember Yang Qianting. glanced at the photo and said directly: "Okay, I'll try to ask her and arrange a time." ”

Of course, in the process of seeing a doctor, several people did not forget to collect the DNA of several doctors: when each doctor was talking, Han Yuchao immediately handed over a tissue and said: "Doctor, your saliva is about to flow out, you wipe it quickly." ”

On the way back, everyone discussed who was the real murderer, and the specific method was to guess ---. There can be a reason or no reason. First of all, everyone ruled out Nie En's suspicion in unison. Some of the rest guessed that it was Ye Yasen, and the other part guessed that it was Chen Yuzhi. guess the former thinks that Ye Yasen is so nervous when he sees Yang Qianting's photo; Only the latter thought that maybe Chen Yuzhi's too calm performance was probably hiding something, because he shouldn't have no impression of the deceased. This is the public saying that the public is reasonable, and the mother-in-law is reasonable. But whose guess is correct, the truth will not be revealed until the DNA test results of the three people come out.

Just when several parties are arguing over each other, and the debate is about to reach a fever pitch. Jiang Chonglang suddenly held up his mobile phone and smiled: "Look, a fish has been hooked." Everyone gathered together to take a look, and it turned out that Ye Yasen applied to add the WeChat of "Yang Qianting" given to him by the serious crime team during the day, and everyone suddenly smiled and clicked "agree". After that, the first sentence that Ye Yasen passed was: "Why are you pregnant again, it's not mine, I remember that we don't have anything inside?" ”

Everyone couldn't help but burst into laughter after watching it, but after the laughter, they couldn't help but feel a little inexplicable and didn't know how to reply. Finally, after deliberation and discussion, try to reply: "What do you say, I don't know, you say more details." ”

The other party immediately replied: "That night, when I was on the night shift. ”

The crowd was even more inexplicable, and they didn't know what to do, so they could only say, "I'll talk about it tomorrow." ”

The next day, everyone went to Ye Yasen's office early in the morning and told Ye Yasen the true situation. Ye Yasen was surprised, but also honestly explained the reason for yesterday's incident. It turned out that Yang Qianting had been restless when she was hospitalized, and when she saw the male doctor, she wanted to throw herself into her arms. Dr. Ye Yasen has also been teased by her several times. After she was discharged from the hospital, one day the two accidentally met on the street. Yang Qianting took the initiative to beckon him to drink, saying that her life was not going well, and why she couldn't meet a good man. Later, the two went to the hotel to open a room, and after getting drunk, they didn't know what happened. Anyway, whether the two have had sex or not, Ye Yasen repeated vigorously like a repeater: "Officer, I don't know, I really don't know; Officer, I don't know, I really don't know; Officer, I don't know, I really don't know ......".

Whether Ye Yasen knew it or not, he was still taken by Jiang Chonglang to the Public Security Bureau for investigation. Jiang Chonglang said, "Doctor Ye, you don't have to say anything. When your DNA test results come back, I'll know if you're lying. ”

Soon the DNA test results of the three people came out, but the results still disappointed the serious crime team. The DNA of the three doctors did not match the DNA of the male saliva on the cigarette butt. In other words, none of the three doctors were the killers of this serial murder.

Just sent Ye Yasen out of the door. saw Zhang Lanshan walking in in a hurry, and as soon as she came in, she asked: "I heard that you arrested Ye Yasen, his DNA does not match the murderer, and the murderer is not him." ”

Jiang Chonglang was stunned for a moment, not knowing what Zhang Lanshan said without a clue: "That's right, so we let him go." ”

This time, Zhang Lanshan was stunned: "We carefully compared the composition of the four groups of DNA, and found that the DNA of the saliva on the cigarette butt was arranged with the DNA of the three suspects. After the analysis of the chromosomes of the male family, it was found that the owner of the DNA of the saliva on the cigarette butt was related to Ye Yasen. If Ye Yasen has a brother, cousin or cousin or something, it is very likely that he is the murderer. ”

"What," Jiang Chonglang was stunned, he didn't expect this relationship. He hurriedly ran out and chased Ye Yasen back, but Ye Yasen thought he had broken the law.

Jiang Chonglang found out the two photos found from Yang Qianting's WeChat and showed them to Ye Yasen. Ask him if he has a brother who is about 1.8 meters tall, tall, thin and has a long face. Ye Yasen looked at it and said, "Yes, his name is Ye Xinwei." It's my uncle's cousin, who is 3 years younger than me, and who is the medical device supplier of our hospital, and he used to be a doctor like me, but three years ago, his girlfriend died in childbirth, and he was the doctor who delivered the baby at that time. I guess I was too sad, so I changed careers. Why, he can't be a murderer. ”

According to Ye Yasen's identification, Jiang Chonglang quickly found Ye Xinwei and tested his DNA. It was found that Ye Xinwei's DNA was the same as the DNA of the man's saliva on the cigarette butt.

In the face of ironclad evidence, Ye Xinwei had nothing to say, and in the interrogation room, facing the police officer opposite. He honestly confessed all the crimes: in the past three years, he has committed all three murders and corpses. In fact, there were not three lives in his hands, but five. The two extra ones are his ex-girlfriend who once betrayed him and the child in her womb.

The police found a photo of his ex-girlfriend from Ye Xinwei's home, and the face in this photo is a bit like Shi Ming, a bit like Liu Qiao, and a little like Yang Qianting. Ye Xinwei's ex-girlfriend is their common "template".

The story behind the murderer: neither so confusing, nor so many joys and sorrows. It is nothing more than a story of a cliché and bloody love triangle.

When Ye Xinwei was just a little doctor a few years ago, he talked about a girlfriend named Qin Ruomei. Qin Ruomei disliked Ye Xinwei, who had no ability and no money. So he slept with other men behind his back, which led to an unexpected pregnancy, and after his belly was big, he lied to Ye Xinwei that this was his species.

At the beginning, Ye Xinwei didn't know that he was cuckolded by Qin Ruomei, and he happily welcomed the arrival of his little life, preparing to get married, and preparing to be upgraded to be a father. But there was an accident, he overheard the call between Qin Ruomei and others, saying that he would like to be a father, and he knew the truth of the matter. It turned out that so much of his efforts were for others to make wedding clothes, and he was so angry at that time that he wanted to kill the woman in front of him immediately, but reason still stopped him.

Ye Xinwei continued to pretend that he didn't know anything, and said that he wanted to deliver his child in person, but Qin Ruomei agreed when he was kept in the dark. When it was time to give birth, Ye Xinwei used a little trick to make Qin Ruomei die with two corpses, and both mother and son died. When recalling this incident now, Ye Xinwei said viciously and regretfully: "The most regrettable thing I did at that time was that I didn't cut open that slut's belly, dig out her heart and liver, and see if it was black or white." ”

After Zhang Lanshan outside the interrogation room saw this scene, she said to Jiang Chonglang next to her: "This is the origin of the distortion of crime, if Ye Xinwei could look at it rationally at that time and calmly choose to break up with his girlfriend, there would not have been so many tragedies later." ”

After the incident, although the family of the deceased had a big quarrel and asked for an autopsy to find out the real cause of death. However, Ye Xinwei took out the so-called "evidence" that had been prepared for a long time, and it was "proven" that the deceased Qin Ruomei had a major physical illness and was not suitable for childbirth, so the matter was over. However, after that, Qin Ruomei's face left a deep imprint in Ye Xinwei's heart, and when she saw it, she would be angry and unhappy for a long time, thinking that they were water-based poplars who liked to seduce men. Therefore, whenever a woman who looks a little like Qin Ruomei comes to see a doctor, he will pay special attention to it.

Because Ye Xinwei's series of strange behaviors attracted the attention of the relevant leaders of the hospital, he finally found an excuse to dismiss him. And Ye Xinwei has no intention of being a doctor, and he has also changed careers to become a medical device supplier. But Ye Xinwei followed his relationship with his cousin Ye Yasen, and often came to the hospital, and occasionally saw some patients. In this way, Ye Xinwei met Shi Ming, Liu Qiao and Yang Qianting successively.
