Chapter 88: Special Occupations
Dr. Lu's words made Zhou Ning couldn't help laughing. This person was pleasant to work with. However, there was nothing wrong with using the excuse of Qindao University's research to investigate. After all, it was an experimental project.
"Then search it!"
Zhou Ning handed the control handle to Xiaoqu. Xiaoqu did not refuse and operated it quickly. The five comparison display frames began to search respectively, but this time it was not as fast as the previous search for Cheng Chunyan.
After more than ten minutes, the display box stopped searching, and there were still question marks in the five comparison boxes. Nothing was found. This discovery made everyone stop their work and come over. Dr. Lu was speechless.
"The first one works, so what's the problem with these few? Did you make any other settings?"
Xiaoqu was also confused and kept shaking his head.
"I don't know. It's the same method as last time, and the operation is exactly the same. I don't know why it didn't find it."
Zhou Ning looked at the electronic file in his hand, raised his head after a while, and said:
"Are you comparing the provincial household registration system?"
Xiao Qu paused, clicked on the option just now, then looked at Zhou Ning and said:
“Yes, this is the provincial household registration system.”
"If we can connect to the national household registration system, then we can try again. The tests on these files show that four out of five people tested positive for HPV, and one tested positive for HIV.
The file suspected that the five people were in special professions. I think if they were engaged in this industry, they were more likely to be from other provinces. After all, no one wants to work in this industry at their doorstep, and once they quit, they can go back to live without knowing about this history. "
Dr. Lu and several people around him nodded.
"The national household registration system can be connected, but the search speed is a little slow. Xiao Qu, please change it quickly and try again."
As soon as Xiaoqu heard it, he quickly started to operate and the comparison began again.
Zhou Ning stared at the flashing comparison images, but what he was thinking about in his mind was the murderer's DNA.
Why would such a cautious person be so hasty this time? Is it just because the 'prey' in his eyes was suddenly left alone?
Although this was a reason, it still seemed reckless for someone who had been at large for five years.
Of course, if the report had been made an hour later, the body would have been swallowed by the sea, but the bloodstains on the windshield showed his haste. How should I put it, it was not perfect.
Yes, that’s the word. The previous cases were perfect, but this one is not perfect enough!
Zhou Ning is a very passive person. From school to work, he has always been very passive. Although he can speak appropriately, it is only because he has no parents and needs to take care of the emotions of many people, so he involuntarily makes himself behave appropriately.
The murderer's pursuit of perfection is a perverted reaction based on physical defects. This perverted reaction is progressive after each crime. Only further perversion can satisfy him.
Ordinary people cannot understand this, but Zhou Ning knows that such a person must have been abused in childhood, or grew up under oppression, which is why he behaves this way.
Just then, a beeping sound interrupted Zhou Ning's thoughts. He looked at the display screen and saw that three of them had found corresponding identity information, and the other two were still being searched.
This discovery made everyone present excited.
It seems that the search direction is correct, and these five people must not be from the province.
After waiting for another ten minutes, the other two also stopped, but there was no photo in the comparison box. Instead, one showed the number 5 and the other showed 7.
"Does it mean that five similar people were found?"
Xiaoqu quickly clicked on the number 5, and sure enough, five identity information appeared behind it. These were five old-style ID cards, with blurry photos and low pixels.
"Forensic Doctor Zhou, these five people have similarities with the fourth victim, so the system has searched them out. The fifth victim has the same problem. I suspect the victim did not get a new ID card."
Zhou Ning quickly looked through the contents of the autopsy report and found that both victims No. 4 and No. 5 were killed in 2006. The time of the crime was March 15th and August 26th respectively.
"In 2004, we started replacing the second-generation ID cards, but most people replaced them in 2007-2008. If you are not local , many people replaced them even later. Print out the information of these people. I will report to Mr. Xu. As for whether to contact the municipal bureau, we will talk about this later."
Dr. Lu came over and looked at Zhou Ning with a smile.
"We are conducting an experiment. As for the verification of the experimental results, you will naturally come to do it. Of course, if you feel it is inconvenient to tell the Municipal Bureau, I can coordinate this. After all, the way we got this information in the first place was also through discussing it with the bureau leaders."
Zhou Ning also laughed. Dr. Lu was such a considerate old man.
"Well, Dr. Lu, I'll go talk to Xu Da first. After these two tests, I think there is no problem with the operation of the software. As long as it can be updated in real time and synchronized with the national household registration information database, there will be no problem in searching."
Dr. Lu still seemed dissatisfied and kept shaking his head.
"The speed of comparison is still too slow. We need to further improve this. Also, if we can synchronize the repair of the blurred portrait you mentioned, then even the old generation of ID cards can be successfully compared."
Zhou Ning nodded. This was indeed the case. Just like now there were twelve similar people found for the two victims, if the blurred portraits could be restored, then the comparison would be much more convenient.
"No hurry, it's already very impressive now. If the experimental report needs our signature and seal, please prepare it. Xiaoqu, send me the information."
Xiaoqu quickly sent the comparison results he had just searched to the laptop that Zhou Ning was holding.
Zhou Ning hurried out of the office and went straight to Xu Dayuan's office. As soon as he came in, he saw Liu Yongxin sitting opposite Xu Dayuan. When he saw Zhou Ning, Xu Dayuan waved his hand.
"Come and sit down. I heard from your master that a special DNA sample was found. Let's not consider whether it is a serial case or not. Let's just investigate this case."
Zhou Ning sat down and placed the laptop in front of the two of them.
"Let's not talk about that for now. Take a look at this. This is the person's ."
The two of them stared at each other for a while. Xu Dayuan's eyes widened and he hid the surprise on his face. He was quite smart and reacted immediately when he saw the five pieces of information behind a person.
"Three of them were found directly, and these two were found with similar ones, is that right?"
Zhou Ning nodded, and Liu Yongxin leaned on the table with a serious expression on his face.
"Xu Da, think about this matter carefully. If we touch upon it, what will be the reaction of the Municipal Bureau?"
Xu Dayuan glared.
"I don't care what they think. We have to continue the investigation. This case happened in our Qidong District. We will not go beyond our boundaries in the investigation. As for these few people, they were just doing it by chance. Can it be that we are wrong after solving the case?"
Xu Dayuan's words made Zhou Ning feel comfortable. Working with a leader like this would give you confidence.
"Anyway, the information was provided by Dr. Lu. I'll ask He Chunyang to verify it one by one. If it doesn't work, I'll send someone over there, or ask a local colleague to help investigate. "
Zhou Ning found the previous autopsy report and pointed to a part of it and said:
"Among these five people, four were HPV positive and one was HIV positive. I think this is related to their profession. We have now found the information of the deceased. We can take their photos and identity information and ask the anti-pornography personnel of the public security brigade to check whether they have been dealt with. This seems to be faster."
Liu Yongxin thought about it and moved closer.
"Since they are similar, why not check both of them? If one is chased away, then both are released. Also, the places where these victims were killed are all in the urban-rural fringe. I think the place where the bodies were killed and dumped won't be too far away. We can just focus on searching around there."
Xu Dayuan grinned, took out his cell phone and dialed a number.
"Lao Liang? What are you doing? I have something to talk to you about. Don't worry, I won't lie to you this time. It's definitely a good thing!"
