Department of Psychology Forensic

Chapter 109 Four People!
In an instant, Zhou Zhengteng stood up abruptly, quickly met Jiang Luoluo who was walking over, and took the report card from the latter.

"let me see……"

Zhou Zheng couldn't wait to open the list, the contents of which would greatly affect the follow-up of the case.

Immediately, the content on the report sheet was constantly presented in his sight, which recorded in detail the DNA profile and comparison results of each bone powder test.

"How?" Cui Jun asked nervously.

"The first, seventh, and eighth copies are the same, they belong to human DNA, and they belong to the same person." Zhou Zheng continued with an extremely serious expression, "The third and sixth copies are consistent, and belong to human beings." The DNA also belonged to the same person, but unlike the matching result of the previous DNA, it belonged to the DNA of a second person."

"Sure enough, it's a case of multiple bones!" Cui Jun's face was ugly. He didn't want to see such a conclusion. He hoped that the results of the scientific appraisal would show that his judgment was wrong, so that there would be fewer victims.

"The second and fifth copies are also human DNA, and the comparison is consistent, and they belong to the same person. This DNA sequence is different from the previous two, and belongs to the third person, but..." Zhou Zheng took a deep breath and said: "From Judging from the DNA sequence, the similarity between this victim and the previous two is as high as 50%, and it should be the child of the other two deceased, moreover, it should be a son."

"A family of three." Cui Jun's face became even more ugly. The nature of such a case is too bad, it is simply a case of extermination.

"The fourth copy..." When Zhou Zheng saw this, his pupils shrank sharply, and a strong shock flashed in his eyes. He raised his head suddenly, moved his eyes away from the report, and stared closely at Cui Jun. Asked: "Master, the fourth bone meal, if I remember correctly, it should come from that skull!"

"How could your memory be wrong!" Cui Jun nodded and said, "It's that cracked head. Tell me, what's wrong?"

"The identification result of the fourth bone powder also belongs to human DNA, which cannot be compared with the previous three, but it is compared with another DNA identified not long ago."

"You mean..." Cui Jun's eyes widened suddenly, and his pupils trembled slightly.

"This is the head of the victim in the cross-sea bridge dumping case!" Zhou Zheng said in a deep voice.

"Immediately apply for a merged case!" Cui Jun immediately took out his mobile phone, he didn't know whose number he had dialed, and got in touch in a hurry.

Holding the report card, Zhou Zheng couldn't calm down for a long time. After a period of silence, he suddenly found that Jiang Luoluo, who had sent the report card, was still standing there.

"Thank you." Zhou Zheng nodded to Jiang Luoluo.

"You're welcome." Jiang Luoluo was a little embarrassed immediately, as if she had never been praised like this before, and then hurriedly said: "Well, I have something to do, so I'll go first."

After finishing speaking, Jiang Luoluo turned and left without staying here too long.

Zhou Zheng stared ahead with serious eyes, he didn't know what he was thinking, and then glanced in the direction of Master, who was on the phone.

Multiplayer bone case!

And... there are still four people!

The nature of such a case is not bad, it will cause great social impact and panic, and the pressure to solve the case will follow.

Zhou Zheng knew very well in his heart that since the Ministry of Public Security put forward the idea that "homicide cases must be solved", the detection of murder cases has become the most important task of the public security organs everywhere.

"I thought the case of dumping corpses on the cross-sea bridge was about to be solved, but I didn't expect that another victim would be involved here. This is already a serial murder case."

Zhou Zhengdun felt confused. He sat at the work station, took out a piece of A4 paper from the printer, and picked up a pen to draw on it.

"The place where the body parts were first found was on the cross-sea bridge, but in fact the place where the body was dumped was Wang Qi's car."

"The second time the body was dumped was at Jianghai North Station."

"The third place where the body was dumped was at the Jianghai Zoo."

"What does this murderer do?"

Zhou Zheng frowned tightly, and strong doubts emerged in his heart. According to the relevant research on criminal psychology, when the murderer of the corpse dumping case often moves the corpse, he will choose the route he feels safe in his heart, and throw the corpse. In a safe area that is not easy to find.

But...Whether it's Wang Qi's car, Jianghai North Station, or the zoo, these are places where dead bodies cannot be hidden.

It can be found almost immediately after the body is thrown.

Why would the murderer do this?
Zhou Zheng rubbed his forehead. He knew that the murderer would not do meaningless throwing of the corpse. If it was thrown away casually, there was no need to go through such a fuss. The distance between these three places is too far, and they form a triangle when connected.

Why do you do this?
The more Zhou Zheng thought about it, the more confused he became. He faintly felt that there was some reason for this, and he had an extremely strong premonition that as long as he found out the reason for throwing the corpse like this, he would find out the murderer.

……

Cui Jun's phone call made the Municipal Bureau pay more attention to the case of dumping corpses in the zoo, and an emergency special meeting was held immediately.

Zhou Zheng attended the meeting together.

The special meeting this time is not in the criminal police office, but in the exclusive conference hall of the Municipal Bureau. There is a big round table that can accommodate very limited people.

There were only seven people in the conference room, Director Ma Yan, Deputy Director Qin Wangde, Criminal Police Captain Xia Yan, Criminal Police Team Zhao Lei, Trace Inspection Department Feng Yu, Forensic Doctor Cui Jun, and Zhou Zheng.

"Everyone's time is very precious. Let's make a long story short and get straight to the point." Ma Yan sat on the main seat with an extremely gloomy face. Recently, a series of major criminal cases occurred in Jianghai City, which made him, the director, bear great pressure , said: "Everyone knows the DNA test results of the bones of the zoo dumping case. The body parts of different victims were thrown into the zoo. This is a very bad case. Standing on the head of the victim of the corpse dumping case, the murderer’s continuous crimes are very obvious. We need to merge these three cases into the cross-sea bridge dumping corpse case. We will set up a special task force, and the team members are present here Everyone."

The scene was deadly quiet, everyone's face was not good-looking, and no one interrupted to speak at this time.

"Since the case is merged and a task force has been set up, everyone's intelligence must be synchronized in real time. If you find something, you don't have to wait until the meeting to announce it. You must inform each other as soon as possible, and work together to strive for the first time. Solve the case." Qin Wangde said, his eyes swept across the crowd, he looked more amiable than Ma Yan, and then said: "Now everyone can speak freely if they have any ideas."

"After the case of dumping corpses in the zoo, we can at least be sure that the murderer is still in Jianghai and has not left." Xia Yan said first.

"Yes, this can be confirmed. Throwing of corpses will not be entrusted to other people, unless they are accomplices." Qin Wangde nodded.

"I'm not sure about one thing. I don't know whether I should say it or not." Zhao Lei hesitated to speak.

"Say!" Ma Yan simply spit out a word.

"I got in touch with Sun Shaoming, the captain of the criminal police in Changnan County. During the further investigation of the Yemei tattoo shop, I found out from the payment records that the ID of the payment WeChat account is 'Xiaoxi', and they have already applied to the telecommunications department. The investigation permit has not yet been approved." Zhao Lei pursed his lips and said.

"Xiaoxi..." Qin Wangde frowned, and said: "XX, not QX or SX, but it takes up an X, maybe the victim's name is Xi, and the abbreviation of the surname is one of Q and S." , This is very important news!"

"That's right, I agree with Bureau Qin's point of view. This is the key information. I think I know how to find out the identity of the victim." Xia Yan suddenly had an idea in his mind, and said, "There is no definite missing person in Jianghai City. The case report shows that the victim is not from this city, so we can investigate the travel records of the tickets. In the past six months, people who bought tickets to enter Jianghai City and did not buy tickets to leave, the big data must have records, and then As long as we find someone named 'Xu Xi', this person is most likely the victim."

"This..." Qin Wangde's mouth twitched fiercely, and he said, "Xia Yan, do you know the daily passenger flow in Jianghai City? In addition to Jianghai Station, there is also the North Station and the airport. There are more than a dozen passengers at the bus station." One, and the bus still does not record the real name, you just said to find people within half a year, this is really 'big data'!"

"It's indeed a bit troublesome, but this is also a solution." Xia Yan said helplessly: "Isn't there no way now!"

"What's the difference between your approach and looking for a needle in a haystack? We know that the needle fell in this place, but we can't get it back!" Qin Wangde shook his head. He understands that if such data is investigated, even if it has a computer system Help, there are not too many qualified people. He has handled a theft case in the past. At that time, he knew that the criminal took a flight to leave Jianghai for Yanjing, and then from Yanjing to Shanghai. It was just two trips to compare the same name. The workload is surprisingly complex.

"Is there a possibility..."

However, at this moment, Zhou Zheng's voice suddenly sounded, which immediately attracted everyone's attention.

"The victim is a local!"

After Zhou Zheng's voice fell, everyone's expressions changed drastically. After all, this was the inference they made in their previous reasoning. If something went wrong from here, then the follow-up direction would be wrong.

"Zhou Zheng, do you have any basis?" Ma Yan narrowed his eyes slightly and asked. Among the people present, he had the least contact with Zhou Zheng, but it didn't mean he didn't know Zhou Zheng. He and Fan Guoliang were very close friends. Friends, Zhou Zheng has been mentioned many times during the chat.

"No." Zhou Zheng shook his head and continued: "However, the basis for us to judge that the victim is not from this city is that no one has reported missing, but judging from the DNA test results of the bones, this is a family of three who were all killed. It’s a murder case, and the body is not at home, so it’s still possible that no one will call the police in a short time.”

"It makes sense." Qin Wangde held his chin and said, "I have accepted a case of sudden death. The deceased stayed up late at home playing games and suffered a sudden cardiac arrest. He rented a house and he was the only one. In addition, he lived on the top floor, and there was no one in the next door, and it was not discovered until half a month later that the smell of corpses wafted from the ventilation duct of the bathroom."

"It does make sense to say that, so we can't investigate purely based on outsiders, and we can't completely investigate based on locals. We must combine the two at the same time until we find relevant evidence." Ma Yan nodded and turned to Xia Yan Looking over, he asked, "Is there any result from the investigation of the doctors in this city?"

"Yes." Xia Yan took out a piece of paper from the file bag in his hand, with a string of names written on it, and said, "There are not many doctors with surgical qualifications in this city. There are three people in total, and their names are Qin Xu, Song Xiu, and Sun Xiao, but no one among them has a hobby of fishing."

"It's easy to hide the hobby of fishing through the in-depth investigation of these three people, but not everyone can master the skills of the scalpel. Unless there is conclusive evidence to rule out their suspicion, otherwise, keep an eye on them." Ma Yan ordered.

"Understood, I have already sent someone to watch." Xia Yan nodded.

"Is there any clue on the zoo monitoring side?" Ma Yan continued to ask.

"The transfer has been completed, and I am searching quickly. Since it is throwing the corpse, I can't determine the specific time. I can only roughly estimate that it was after the Siberian tiger ate for the last time. The surveillance video in the park and the video in the lion and tiger park are all quickly Investigate." Xia Yan replied.

"Forensic Cui, did you find anything over the corpse?" Ma Yan shifted his gaze to Cui Jun.

"I'm going to conduct a second autopsy." Cui Jun said solemnly with stern eyes: "We didn't conduct the first autopsy very carefully, mainly because we found that the bones did not seem to belong to the same person. Now that the DNA test results are out, we are going to The bones are grouped and the bones of the same victim are put together so that the next step of inspection can be carried out."

"Then I'll leave it to you, try your best to find enough clues to prove the identities of these people, and bring us back from the passive situation." Ma Yan stared at Cui Jun, and he understood Cui Jun's words in his heart, unlike the victim's body If some parts are put together for inspection, not only will no information be obtained, but it will interfere with each other.

……

As Director Ma Yan said at the beginning, the project will end soon without delaying everyone's time.

At this moment, Zhou Zheng and Cui Jun changed into their autopsy suits and stood in front of the moving corpse bed, regrouping the marked bones. After putting together the body parts of the same person, the second autopsy would begin.

　Ask for a monthly ticket at the beginning of the month, thank you for your support!
