Chapter 92 It’s him!

Ring ring ring!

A rapid ringing of the phone pulled Zhou Ning out of the anatomy training. He was so groggy from the hangover that he shook his head. He struggled twice before grabbing the phone. When he saw the word "Xuda", he yawned halfway.

They were all frightened.

"Xu Da!"

"You haven't gotten up yet?"

"If the leader has any orders, just tell him directly. This is really scary."

"Haha, you must have drank a lot. It's already past ten o'clock. Come to the team quickly. Don't you remember the task you assigned me last night?"

Zhou Ning was stunned for a moment and recalled it carefully. He suddenly remembered that after he separated from He Shancun, he seemed to have called Xu Dayuan. As for the content, he had completely forgotten it at the moment. After all, that part was already fragmented, so he quickly asked tentatively.

"Xu Da, I'm going now, but what did I tell you?"

"Zhou Xiaozhou is playing with me, right?"

Zhou Ning was so scared.

"How can I, wait a minute, I remembered, the direction of the investigation, I told you last night that I changed the direction of the investigation, and look for those private men's hospitals or infertility institutions in the provincial capital that have better advertising effects.

I just woke up and my brain is a little slow to start up."

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

After hanging up the phone, Zhou Ning got up, washed himself, put on his clothes and rushed out, arriving at the criminal police team ten minutes later.

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

Besides, if Xu Dayuan really wanted to reprimand him, it would not be in this tone. It seemed that the provincial capital had discovered something, but in order to quickly metabolize the remaining alcohol in his body, he did not rush and just jogged to the second floor.

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

Following the voice, Xu Dayuan was actually in Dr. Lu's office, talking to Liu Yongxin and others.

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 remains from World War II, as well as bones from uninhabited graves discovered during excavations on surrounding roads. Anyway, they can be tested.

There is a lot of material.

As soon as Zhou Ning put his head in, Xu Dayuan seemed to have eyes on the back of his head, and he opened his mouth and shouted:

"Stop poking around, Zhou Xiaozhou, come in quickly."

"What's wrong, leader?"

Xu Dayuan waved his hand, and Zhou Ning quickly walked to Liu Yongxin's side. On the computer screen, there were surveillance images one after another. At a glance, there were more than forty on this page alone.

"This is the surveillance of several private andrology and infertility institutions in the provincial capital. Dr. Lu just asked people to check it. They usually save the surveillance videos for a month, but the files will be kept for a long time, and in the clinic, patients will be seen

The staff took photos and archived them.”

Following Liu Yongxin's introduction, Xiaoqu has adjusted the picture. At this moment, there are pictures one after another. The top is a photo from the doctor's perspective. The photo is very high-definition and includes both the patient's file and himself.

"I feel that the murderer of the 3.10 case knew that he had sex chromosome abnormalities very early on, so the surveillance search is of little significance. It is better to screen all the people with XXY abnormalities in these files from 2005 to 2010. These talents

This is the scope of our investigation."

Xu Dayuan looked at Zhou Ning and nodded repeatedly.

"You don't have to go back to 2005 to see when they started keeping files. Let's not let anyone go. After all, the number of such patients is not particularly large and it is easier to screen."

Xiaoqu smiled and nodded.

"I'll give it a try. It's very fast. The electronic medical files they save all have the names of the diseases."

As he spoke, his hands started to operate with crackling sounds. In a moment, many files appeared on the huge display screen, and a number 447 appeared behind the search box below. This number was very large.

Xiao Qu turned around and handed the mouse control panel to Zhou Ning.

"Four hundred and forty-seven patients with XXY sex chromosome abnormalities are concentrated in these two Putian men's hospitals. Later I will compare the information with the public hospitals. Patients with medical insurance can use their real names, and those who pay for themselves can do so.

Choose your real name.”

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

"Zhou Xiaozhou, have you and Forensic Doctor Liu done anything to portray the murderer? In what aspects should we screen?"

Zhou Ning looked at Liu Yongxin, who nodded towards him.

The meaning was obvious, so he let him go and said that after all, in this case, the two of them had already studied some of the details of the murderer, including the intensity and direction of the torture injuries, as well as the length of the scratches in the vagina of the deceased.

"Regarding the scene and autopsy analysis of the 3.10 case, I think the murderer was not tall and thinner than ordinary men. Only in this way can he reduce his danger level. Otherwise, even if a burly man pretends to be injured on the roadside, Cheng Chunyan will not

Come and help.

As for age, combined with the time of the Hongyi serial murder case, from 2006 to now, this person is at least 22 years old. I asked Director He that most patients with XXY chromosome abnormalities have no obvious secondary sexual characteristics, or

Development is extremely slow, and the youngest person who commits a crime for the first time is 17 years old, that is, those born before 1989.

In addition, judging from the scratches on the body of the deceased, the longest finger of the murderer was 7.5cm. According to normal proportions, the murderer's hand was 16-17.5cm long, which is smaller than the hands of ordinary girls.

, so we estimate that the maximum height of the murderer is no more than 170cm.

Of course, there is another point, that is, people with registered residence in Qindao, or people from nearby seaside cities, after all, they know the tides quite well, because the tides in the sea area around our Qindao are very different from other places."

Liu Yongxin kept nodding aside, obviously very much approving of Zhou Ning's judgment. Xu Dayuan took out a small book and quickly recorded what Zhou Ning said. There are very few clues to find the murderer on a corpse. It is already very difficult to think about it to this extent.

It is difficult for forensic scientists to do their job.

"Okay, Xiaoqu, please first conduct a rough screening according to the age range we gave, and compare it with the same patients from major universities and middle schools in the provincial capital last night, and we will make detailed judgments on the selected people.

investigation."

Xiaoqu didn't talk nonsense and quickly started screening. After all, a large part of them were minors, so the screening speed was not slow. Then they compared it with similar patients in major key hospitals in the provincial capital. After ten minutes, the screen

There are only 154 files left.

Seeing Xiao Qu 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 couldn't see their height, they could still make comparisons while sitting.

Zhou Ning looked at them one by one. He eliminated those who were too feminine, had long pointed nails, and those who clearly showed incomplete development of the generator in the case, and then opened a file marked with the patient's name Yang Guang.

At this moment, Zhou Ning made a move.

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

Looking at Zhou Ning and then looking at the screen, the file date was August 12, 2004. The man was wearing a hat and glasses, with his hands curled up in his sleeves. His date of birth was February 24, 1979. Liu Yongxin didn't find anything special.

place.

"What's wrong?"

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

"This man is Cui Guanglin, my sister Zhou Xiaoyu's boyfriend. We just met last night. Although he was disguised with a hat, I remember the mole on his nose."

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

"Now that he has been screened out, it is obvious that he also has a chromosomal abnormality. Don't your second uncle and the others know about it?"

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

"No wonder this kid behaves like this. It seems that he already knew that he had a physical problem. What's the point of hiding it like this? I'll call Lao Zhou later and make it clear that I can't have this kid."

Zhou Ning shook his head.

"Let me tell you, it's not appropriate for my second uncle to talk about this matter. And even if we break up, we can't let the other party know that we found out about this. After all, they still work in the same high school."

Liu Yongxin nodded and patted Zhou Ning on the shoulder.

"You're right, but since this kid has been screened out, let's check when he went to see a doctor."

Xu Dayuan understood what Liu Yongxin meant and nodded accordingly, but Zhou Ning lowered his head and pondered for a moment. He recalled the details of meeting Cui Guanglin last night. He didn't have a strong sense of size when shaking hands, but there were band-aids on his fingers. This made him feel even more...

worries.

His shoulder was bumped by Liu Yongxin. He raised his head and smiled at Liu Yongxin, and quickly continued the work at hand.

After half an hour, the screening work was completed. At this time, there were only 32 people left.

"I will make arrangements now to check the real information of these people, and then start to investigate one by one, one is the time of the crime, 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, Mr. Xu, I want to confirm all the time of occurrence of this serial murder case in red from the city bureau."

Xiaoqu directly clicked on a file, and all the times appeared on the screen like a list. All the bodies were found in February, March, August and September.

However, if we estimate the time of death of the deceased, it is basically February and August. If the city bureau came last time and judged that this case was not a serial murder case at a glance, I am afraid that the time should also be considered.

a little bit.

"Xu Da, check Cui Guanglin first, not because of Zhou Xiaoyu, but when I was eating last night, I remembered that Cui Guanglin had a band-aid on his finger, and except for the 3.10 case, all the crimes occurred in February and August.

This is the winter and summer vacation.”

Xu Dayuan and Liu Yongxin were both stunned, their faces becoming more solemn.

"Then check him first!"

Sorry, I just finished my work and the update is a bit late!
Chapter completed!
