novice forensic medicine

Chapter 92 It turned out to be him!

Ring Ring Ring!
A rush of phone ringing pulled Zhou Ning out of the anatomy training. He shook his head and was drowsy from the hangover. He struggled twice before grabbing the phone. When he saw the word Xu Da, he yawned halfway. They were all scared.

"Da Xu!"

"Aren't you up?"

"It's scary for the leader to tell you what to order."

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

Zhou Ning was taken aback, recalled it carefully, and instantly 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 hurriedly asked tentatively.

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

"Zhou Xiaozhou is playing with me, right?"

Zhou Ning was too scared.

"Wait, wait until I remember, the direction of the investigation, I told you last night that I changed the direction of the investigation, to look for those private andrology 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."

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

After finishing speaking, the phone was hung up, Zhou Ning got up with a grunt, washed up, put on his clothes and rushed out, and arrived at the criminal police team 10 minutes later.

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

Besides, Xu Dayuan really wanted to reprimand him, so it was not in this tone. It seemed that the provincial capital had discovered it, but in order to quickly metabolize the remaining alcohol in his body, he was not in a hurry, so he just trotted to the second floor.

As soon as he went up to the second floor, he 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 the others.

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

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 poke your head around, Zhou Xiaozhou come in quickly."

"What's wrong, leader?"

Xu Dayuan waved his hand, and Zhou Ning hurried to Liu Yongxin's side. On the computer screen, there were monitoring pictures one by one. At a glance, there were more than 40 on this page alone.

"This is the monitoring of several private andrology and infertility institutions in the provincial capital. Dr. Lu just asked people to check it. They usually keep the surveillance video for a month, but the files will be kept for a long time, and in the clinic, they will be sent to the doctor. The staff took photos and archived."

Following Liu Yongxin's introduction, Xiaoqu has adjusted the screen. At this moment, there are pictures one by one. The picture above is a picture from the doctor's perspective. The picture is very clear, and both the patient's file and himself are taken in.

"I feel that the murderer in the 3.10 case knew about his sex chromosome abnormality very early on, so the monitoring search is of little significance. It is better to screen all those with XXY abnormalities in these files from 2005 to 2010. These talents That's the scope of our investigation."

Xu Dayuan looked at Zhou Ning and nodded repeatedly.

"It doesn't have to be 2005. Let's 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 easier to screen."

Xiao Qu smiled and nodded.

"Let me try it. It's very fast. The electronic medical records they keep all have the names of the diseases."

As he said that, he started to operate with crackling hands, and for a while, many files appeared on the huge display screen, and a number 447 appeared behind the search box below, which is a huge number.

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

"440 patients with seven XXY sex chromosome abnormalities are concentrated in these two Putian male hospitals. Later, I will compare the information with the public hospitals. Patients with medical insurance can use their real names, and those who pay their own expenses can choose their real names. .”

Xu Dayuan nodded, and Zhou Ning clicked on a photo to start checking. There are more than 400 people. If every one of them is carefully investigated, it will take unimaginable manpower and material resources.

"Zhou Xiaozhou, have you and Forensic Doctor Liu made a portrait of the murderer? From what aspects do we screen?"

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

The meaning was obvious, so let him let go and say, after all, in this case, the two of them had already studied some details of the murderer, from the intensity and direction of the abuse injuries, and 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 is not tall and thinner than ordinary men. Only in this way can he reduce his danger. Otherwise, Cheng Chunyan would not Come and help.

As for the age, combined with the time of the serial murder case in red, from 2006 to the present, this person must be at least 22 years old. I asked Director He that most patients with abnormal XXY chromosomes have no obvious secondary sexual characteristics, or The development is extremely slow, and the youngest person who committed the crime for the first time was 17 years old, that is, people born before 1989.

In addition, judging from the scratches on the body of the deceased, the length of the murderer's fingers, the longest finger is 7.5cm, inferred according to the normal proportion, the murderer's hand length is 16-17.5cm, which is smaller than the hands of ordinary girls , so we estimate that the maximum height of the murderer is no more than 170.

Of course, there is another point, that is, the household registration of Qindao, or the personnel of the surrounding seaside cities. After all, he knows the tides quite well, because the tides in the sea area around Qindao are very different from those in other places. "

Liu Yongxin kept nodding at the side, apparently approving of Zhou Ning's judgment, Xu Dayuan took out a small notebook and quickly recorded what Zhou Ning said, there were very few clues to find the murderer on a dead body, it was already very difficult to think about it to this extent. Difficult for forensic work.

"Okay, Xiaoqu, first, according to the age range we gave, compare it with the same patient in the provincial capital and high school last night, you first conduct a rough screening, and we will make a detailed judgment and evaluation of the screened out people. investigation."

Xiao Qu didn't talk nonsense, and quickly started screening. After all, a large part of them are minors, so the screening speed is not slow, and then compared with similar patients in major hospitals in the provincial capital. Ten minutes later, the screen There are only 154 files left on the website.

Seeing Xiaoqu stop, Zhou Ning walked over, took the mouse, and opened each file to observe. After all, most of them have photos and electronic medical records. Although the height cannot be seen, it can be compared while sitting.

Zhou Ning looked at them one by one. There were those who were too feminine, those with pointed and long nails, and those who clearly showed that the birth organ was not fully developed. Zhou Ning paused.

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

Look at Zhou Ning and look at the screen again. The file date is August 2004, 8. This person is wearing a hat and glasses, with his hands curled up in his sleeves. The date of birth is February 12, 1979. Liu Yongxin did not find anything special place.

"what happened?"

Zhou Ning zoomed in on the picture, and the whole screen was filled with the features of this person's face. 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 himself, I still remember the mole on his nose."

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

"Since it was screened out, it is obvious that he also has a chromosomal abnormality. Don't your second uncle know?"

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

"No wonder this kid behaved like this. It seems that he already knew that he had a physical problem. There is nothing to consider in hiding it like this. I will call Lao Zhou later to clarify that this kid can't have it."

Zhou Ning shook his head.

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

Liu Yongxin nodded and patted Zhou Ning on the shoulder.

"You're right, but since this kid was screened out, let's see when he went to see a doctor. Let's screen it out."

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, which made him feel even stronger. concerns.

His shoulder was bumped by Liu Yongxin, he raised his head and smiled at Liu Yongxin, and quickly resumed his work.

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

"I'm going to make arrangements now to check the real information of these people, and then start to check one by one, one 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 blocked Xu Dayuan's arm.

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

Xiao Qu directly clicks on a file, and all the times appear on the screen like a list, all of which are corpses discovered in February, March, August and September.

However, if you estimate the time of death of the deceased, it is basically 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 a serial murder case. I am afraid that the time is also considered. a little bit.

"Xu Da, check Cui Guanglin first. It's not because of Zhou Xiaoyu's relationship, but when I was eating last night, I remembered that Cui Guanglin had Band-Aids on his fingers. Besides this 3.10 case, all the cases occurred in February and August. This is summer and winter vacation."

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

"Then check him first!"

　Sorry I just got busy, the update is a bit late!
