Bell bell bell!

A rapid phone ringing pulled Zhou Ning out of the anatomy training, shaking his head and the hangover made him groggy, and he struggled twice before grabbing the phone, and when he saw Xu Da's two words, he was scared when he yawned halfway.

"Xu Da!"

"Didn't you get up?"

"What does the leader have to say, it's weird and scary."

"Hehe, you've drunk a lot, it's past ten o'clock, hurry up and come to the team, don't you remember the task you assigned me last night?"

Zhou Ning was stunned for a moment, recalled it carefully, and instantly remembered that after separating from He Shancun, he seemed to have called Xu Dayuan, as for the content, he had forgotten everything at the moment, after all, that part had been somewhat fragmented, and hurriedly asked tentatively.

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

"Zhou Xiaozhou, you're playing with me, right?"

Zhou Ning was so frightened that he couldn't do it.

"How can it, wait until I remember, the direction of the investigation, I told you last night that I changed the direction of the investigation, and went to those private men's hospitals or infertility institutions in the provincial capital where the advertising effect is better, I just woke up, and my brain is a little slow to start."

"Alright, don't talk nonsense and come here."

After finishing speaking, the phone was hung up, Zhou Ning got up with a grunt, washed up and put on his clothes, and rushed out, and arrived at the criminal police team ten minutes later.

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

Besides, Xu Dayuan really wants to train him, it's not this tone, it seems that the provincial capital seems to have made a discovery, but in order to let the remaining alcohol in his body be metabolized quickly, he is not in a hurry, so he trotted to the second floor.

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

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

Although it was Saturday, the people in the software research team were basically there, after all, Dr. Lu found a lot of skulls for them, including the remains of the previous World War II, as well as the bones of uninhabited tombs found during the excavation of the surrounding roads, anyway, there are a lot of materials that can be tested.

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

"Don't probe your brain, Zhou Xiaozhou hurry in."

"What's wrong with the leader?"

Xu Dayuan waved his hand, Zhou Ning hurriedly walked to Liu Yongxin's side, on the computer monitor, there were monitoring screens, and at a cursory glance, there were more than forty of them.

"This is the monitoring of several private andrology and infertility institutions in the provincial capital, just now Dr. Lu has asked people to view, they generally keep a month's surveillance video, but the file will be kept for a long time, and in the consultation room, the patients will be photographed and archived."

With Liu Yongxin's introduction, Xiaoqu has adjusted the picture, and at this moment it is a picture, on which is a photo from the doctor's point of view, the photo is very high-definition, and the patient's file and himself are taken in.

"I feel that the murderer of the 3.10 case knew that he had sex chromosome abnormalities very early, so it is of little significance to monitor the search, or to put these files in 2005 to 2010, all people with XXY abnormalities will be screened uniformly, and these people are the scope of our investigation."

Xu Dayuan looked at Zhou Ning and kept nodding.

"You don't have to have to be in 2005 to see when they started keeping files, let's not let one go, after all, the number of such patients is not particularly large, and it is relatively easy to screen."

Xiaoqu smiled and nodded.

"I'll try it, it's fast, and the electronic medical files they keep have the name of the illness on them."

As he spoke, his hand crackled and operated, and in a moment a lot of files appeared on the huge display screen, and a number 447 appeared behind the search box below, which is a huge amount.

Xiaoqu turned around and handed the mouse operation disk to Zhou Ning.

"Four hundred and forty-seven patients with XXY sex chromosome abnormalities are concentrated in these two Putian men's hospitals, and I will compare it with the information in the public hospital later, and patients with medical insurance can have their real names, and those who pay their own money can choose their real names."

Xu Dayuan nodded, Zhou Ning clicked on a photo and began to view, more than four hundred people, if each one of them was carefully investigated, it would take unimaginable manpower and material resources.

"Zhou Xiaozhou, have you and Forensic Doctor Liu ever portrayed the murderer? What do we screen for? ”

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

The meaning was obvious, so he let go and said, after all, in this case, the two of them had already studied some details and characteristics of the murderer, from the strength and direction of the torture injuries, as well as the length of the scratches in the deceased's hallway.

"For the scene and autopsy analysis of the 3.10 case, I think the murderer is not tall, thinner than ordinary men, only in this way can his danger be reduced, otherwise a burly person, even if he is injured on the side of the road, Cheng Chunyan will not come to help.

As for age, combined with the time of the red-clothed serial murder case, from 2006 to the present, this person is at least 22 years old or older, I asked Director He, most of the patients with XXY chromosomal abnormalities have no obvious secondary sex characteristics, or are extremely stunted, and the youngest of the first offender is 17 years old, that is, people born before 1989.

In addition, judging from the scratches in the deceased's body, the length of the murderer's finger, the longest finger is 7.5cm, and according to the normal proportion, the length of the murderer's hand is 16-17.5cm, which is smaller than the average girl's hand, 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 Qindao, or the people in the surrounding cities near the sea, after all, he knows the tides quite well, because the tides in the waters around Qindao are very different from other places. ”

Liu Yongxin kept nodding on the side, obviously recognizing Zhou Ning's judgment very much, Xu Dayuan took out a small notebook and quickly recorded what Zhou Ning said, there are very few clues that can find the murderer on a corpse, and it is already very difficult for forensic doctors to be pondered to this extent.

"Okay, Xiaoqu, you first follow the age range we gave, compared with the same patients in the provincial capital last night, you first conduct a rough screening, and we will make a detailed judgment and investigation of the screened personnel."

Xiaoqu didn't talk nonsense, and hurriedly started screening, after all, a large part of them are minors, so the speed of screening is not slow, and then compared with similar patients in major key hospitals in the provincial capital, after ten minutes, the number of files left on the screen is only 154.

Seeing Xiaoqu stop, Zhou Ning walked over, took the mouse, and opened each file for observation, after all, most of them have photos and electronic medical records, although they can't see their height, they can also make comparisons while sitting.

Zhou Ning looked at the past one by one, there were those who were too feminine, with long pointed nails, and those that clearly showed that the biovalue was not fully developed in the cases, and they were eliminated one by one, and when he opened a file marked with the patient's name Yang Guang, Zhou Ning moved.

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

Look at Zhou Ning and look at the display screen, the file date is August 12, 2004, this person is wearing a hat and glasses, his hands are curled up in his sleeves, the date of birth is February 24, 1979, Liu Yongxin did not find anything special.

"What's wrong?"

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

"This person is my sister Zhou Xiaoyu's boyfriend Cui Guanglin, we only met last night, although he wore a hat and disguised, but I remember this mole on his nose."

Liu Yongxin was also stunned, he didn't expect to meet acquaintances in such a scene.

"Since it has been screened out, it is obvious that he is also chromosomal abnormal, don't you know about your second uncle?"

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

"No wonder this kid behaves like this, it seems that he already knows that he has a physical problem, what else is there to consider in this concealment, I will call Lao Zhou in a while to make it clear, this kid can't ask for it."

Zhou Ning shook his head.

"Let's talk about it, it's not appropriate for the second uncle to talk about this, and even if they break up, they can't let the other party know that we found out this, after all, they are still working in a 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 see when he went to see a doctor, let's take a good look at it."

Xu Dayuan understood what Liu Yongxin meant, and nodded his head, but Zhou Ning lowered his head and pondered for a moment, he recalled the details of seeing Dao Cui Guanglin last night, and the handshake did not have a strong perception of the size, but there was a band-aid on his finger, which made him even more worried.

was bumped on the shoulder by Liu Yongxin, he looked up and smiled at Liu Yongxin, and hurriedly continued the work at hand.

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

"I'll arrange it now, 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 injuries on the body."

"Well, I approve of 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 times of the red-clothed serial murder case in the city bureau."

Xiaoqu clicked directly on a file, and all the time had become a list appeared on the display, all of which were corpses found in February, March, August, and September.

However, if you estimate the time of death of the deceased, then it is basically the time of February and August, if you say that the last time the city bureau came, you can judge that this case is not the basis for serial murder at a glance, I am afraid that the time is also a point to consider.

"Xu Da, check Cui Guanglin first, not because of Zhou Xiaoyu's relationship, but when I had dinner last night, I remember that Cui Guanglin had a band-aid on his finger, and except for this 3.10 case, all the cases occurred in February and August, which is the winter and summer vacation period."

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

"Then check him first!"
