Chapter 92 It turned out to be him!

Ring ding ding ding ding !

A rapid phone ringing pulled Zhou Ning out of the anatomical training, shook his head and hangover made him feel drowsy. He struggled for a few times before grabbing his phone. Seeing the words Xu Da, he was scared to death by yawning halfway through.

"Xu Da!"

"Didn't get up?"

"If the leader has any instructions, it's scary."

"Haha, you have drunk a lot. It's past ten o'clock. Come to the team quickly. Do you remember the task you assigned to me last night?"

Zhou Ning was stunned, recalled carefully, and instantly remembered that after he separated from He Shancun, he seemed to have called Xu Dayuan. As for the content, he forgot all the content at this moment. After all, that part was already a bit broken, so he asked tentatively.

"Xu Da, I'll go now, but what did I say to you?"

"Zhou Xiao Zhouyi is playing with me, right?"

Zhou Ning was so scared.

"Where can it be? I've remembered the direction of the investigation. Last night, I told you that I changed the direction of the investigation and looked for those private andrology hospitals or infertility institutions in the provincial capital. I just woke up and my brain turned on was a little slow."

"Okay, stop talking nonsense and come here quickly."

After saying that, the phone had already hung up. Zhou Ning got up, washed up, put on his clothes and rushed out. Ten minutes later, he arrived at the criminal police team.

He didn't take a taxi. He invited He Shancun to dinner last night, which was already an unexpected expense this month.

Besides, Xu Dayuan really wanted to scold him, but this was not the tone. It seemed that there was a discovery in the provincial capital, but in order to quickly metabolize the remaining alcohol in his body, he was not in a hurry and ran to the second floor.

As soon as I went up the second floor, I heard Xu Dayuan's loud voice, as if he was calling someone, and his tone was quite domineering.

Looking at the sound, Xu Dayuan was actually talking to Liu Yongxin and the others in Dr. Lu's office.

Although it was Saturday, most of the people from the software research team were there. After all, Dr. Lu found a lot of skulls for them, including the remains of World War II and the remains of the unmanned tombs during excavation on surrounding roads. Anyway, there are a lot of materials that can be tested.

Zhou Ning just leaned his head, and Xu Dayuan seemed to have eyes on the back of his head, and opened his mouth and shouted:

"Don't just stumble, Zhou Xiaozhou comes in quickly."

"What's wrong with the leader?"

Xu Dayuan waved his hand, and Zhou Ning quickly walked to Liu Yongxin. On the computer display screen, there were surveillance screens. A brief look at this page alone, there were more than 40.

"This is the surveillance of several private andrology departments and infertility institutions in the provincial capital. Dr. Lu just asked someone to check it out. They usually keep surveillance videos for one month, but the files will be kept for a long time, and in the clinic, they will take photos and archive them for the medical staff."

With Liu Yongxin's introduction, Xiaoqu has adjusted the picture, and now there are pictures, with a photo from the doctor's perspective. The photo is very clear, and he took both the patient's files and himself.

"I feel that the murderer of the 3.10 case knew that he had sexual chromosome abnormalities very early, so the search for surveillance is not very meaningful. I will just screen these files from 2005 to 2010. Those who have XXY abnormalities will be uniformly screened. These people are our scope of investigation."

Xu Dayuan looked at Zhou Ning and kept nodding.

"You don't have to 2005. Let's see when they started keeping archives. Let's not let one go. After all, there are not many such patients and it is easier to screen."

Xiaoqu nodded with a smile.

"I'll try it. This speed is very fast. The electronic medical files they keep all contain the names of the disease."

As he said that, his hands started to operate, and for a moment, many files appeared on the huge display screen. A number 447 appeared behind the search box below, which is very large.

Xiao Qu turned around and handed the mouse operating disk to Zhou Ning.

"The four hundred and forty-seven patients with XXY sex chromosome abnormalities are concentrated in these two Putian-based andrology hospitals. I will compare the information in the public hospital later. Patients who use medical insurance can have real names, and those who are at their own expense can choose their real names."

Xu Dayuan nodded, Zhou Ning clicked on a photo and started to check it out. There were more than 400 people. If each of them investigated carefully, the manpower and material resources required would be unimaginable.

"Zhou Xiaozhou, have you and Forensic Liu portrayed the murderer in an image? What aspects do we screen?"

Zhou Ning looked at Liu Yongxin, and Liu Yongxin nodded at him.

The meaning was obvious, so he let go. After all, in this case, the two of them had long studied some of the details of the murderer, from the intensity of the abuse and the direction of the injury, as well as the length of the scratches in the deceased's shading avenue.

"For the on-site and autopsy analysis of the 3.10 case, I think the murderer is not tall and thinner than an ordinary man. Only in this way can he reduce his danger. Otherwise, a burly man, even if he is injured in disguise on the roadside, Cheng Chunyan will not come to help.

As for age, combined with the time of the serial murder case in red, from 2006 to the present, this person is at least 22 years old. I asked Director He that most patients with XXY chromosome abnormalities have little secondary characteristics or are extremely slow in development. The youngest person who committed the first crime was 17 years old, that is, people born before 1989.

In addition, based on the scratches in the deceased's body, the length of the murderer's finger is 7.5cm. According to the normal ratio, the murderer's hand is 16-17.5cm, which is smaller than the hands of ordinary girls, so we estimate that the murderer's height is no more than 170.

Of course, there is another point, that is, the household registration of Qin Island, or people around the seaside cities. After all, he knows a lot about tides because the tides in the sea around Qin Island are very different from other places."

Liu Yongxin kept nodding, obviously very much in his opinion. Xu Dayuan took out a small notebook and quickly recorded what Zhou Ning said. There were very few clues to the murderer on a corpse. It was already very difficult for the forensic doctor to work to this extent.

"Okay, Xiaoqu, please first compare the same patients in all major and middle-aged provincial capitals as we have selected last night. You will first conduct a rough screening. Let's make detailed judgments and investigations according to the age range we have given."

Xiao Qu didn't say nonsense and started screening quickly. After all, a large part of it was minors, so the screening speed was not slow. Then he compared it with similar patients in major key hospitals in the provincial capital. After more than ten minutes, the remaining files on the screen were only 154.

Seeing Xiaoqu stop, Zhou Ning walked over, took the mouse, and opened each file to observe. After all, most of them had photos and electronic medical records. Although they could not see their height, they could also make comparisons while sitting.

Zhou Ning looked at it one by one, and some were too feminine, with long pointed nails, and those clearly showed that the value generator was not fully developed in the case, were eliminated one by one. When opening a file marked with the patient's name Yang Guang, Zhou Ning paused.

Zhou Ning's actions attracted Liu Yongxin's attention.

Looking at Zhou Ning, he looked at the display screen again. The archive date was August 12, 2004. The man was wearing a hat and glasses, his hands curled up in his sleeves. The date of birth was February 24, 1979. Liu Yongxin found nothing special.

"What's wrong?"

Zhou Ning enlarged the picture, and the screen was full of features of the person's face. After careful identification, he looked at Liu Yongxin.

"This person is Cui Guanglin, the boyfriend of my sister Zhou Xiaoyu. We only met last night. Although we were wearing a hat and pretending, I remember the mole on my nose."

Liu Yongxin was also stunned. He didn't expect that he could meet an acquaintance in such a scene.

"Since he has screened it, it is obvious that he has chromosomal abnormalities. Don't you know about your second uncle?"

Zhou Ning shook his head and briefly told him about what happened last night, and Xu Dayuan also came over.

"No wonder this kid is acting like this. It seems that he has known that he has a physical problem for a long time. What else can I consider hiding this way? I will call Lao Zhou later and make it clear that this kid cannot ask for it."

Zhou Ning shook his head.

"It's better for me to say that this is not appropriate for Uncle Second, and even if we break up, we can't let the other party know that we found out about it. After all, they are still working in the same high school."

Liu Yongxin nodded and patted Zhou Ning on the shoulder.

"You are right, but since this kid has been screened out, let's see when he went to see a doctor. Let's have a good screening."

Xu Dayuan understood what Liu Yongxin meant and nodded, but Zhou Ning lowered his head and pondered for a moment. He recalled the details of seeing Cui Guanglin last night. He shook hands with his hands and felt that the size was not strong, but there was a band-aid on his fingers, which made him even more worried.

Liu Yongxin hit his shoulder, he looked up and smiled at Liu Yongxin, and quickly continued the work on his hands.

In half an hour, the screening work was completed, and at this time there were only 32 people left.

"I will arrange it now and check the real information of these people, and then start checking one by one, one of which is the time of the incident and the other is whether there are any injuries on the body."

"Well, I agree with Xu Da's arrangement."

Zhou Ning raised his hand and stopped Xu Dayuan's arm.

"Don't worry, Xu Da, I want to confirm all the incident time of this red-clothed serial murder case in the Municipal Bureau."

Xiaoqu directly clicks on a file, and all the time has become a list and appears on the display screen, all of which are bodies found in February, March, August and September.

However, if you estimate the death time of the deceased, it will basically be the time of the case in February and August. If the city bureau came last time and just took a look at it, it is probably a matter of time to consider it.

"Xu Da, first investigate Cui Guanglin, it was not because of Zhou Xiaoyu, but when I was having dinner last night, I remember Cui Guanglin had a band-aid sticker on his finger. Besides this March 10 case, all cases were in February and August, which was winter and summer vacations."

Xu Dayuan and Liu Yongxin were both stunned, and their faces became more and more serious.

"Then check him first!"

Sorry, I just finished my busy schedule, and some updates are a little late!
