Mystery Case Tracing [Criminal Investigation]

There was a deathly silence in the conference room, and the whistling sound from the projector radiator fell clearly into everyone's ears.

"Tell me what you think." Zhang Chao looked at Qi Chuchen.

"Just said Lu Zhongyan, Meng Handong had close contact with Chen Jia some time before his death. I don't have this specific piece of information at hand. Could you please tell me how this specific contact was made?" Qi Chuchen looked at Gao Rui.

Gao Rui organized the language and began to introduce this "close contact" to everyone again in writing.

The police technically retrieved the QQ and WeChat exchange records of Chen Jia and Lu Zhongyan, and found that the two were in several QQ "special friendship groups". They didn't say anything in the group, but they added friends in private. Lu Zhongyan had sent out special invitations to Chen Jia several times. Chen Jia's reply was ambiguous, and he did not directly agree on QQ.

The two also added friends on WeChat. The addition time was more than ten days before Lu Zhongyan was killed. There were many video chat records in WeChat. Besides that, Chen Jia did not send any voice or text content, but Lu Zhongyan sent a sassy from time to time. Voice, and still did not give up the appointment with Chen Jia.

Probably, Lu Zhongyan was hacked by Chen Jiala more than a week before his death, and it seemed that Chen Jia was unbearable to harass him. In addition to Chen Jia, we have also found that Lu Zhongyan and many people have sent such invitations, and most of them have been made.

Meng Handong has money. He fills up the most senior VIPs in the bars he frequents. He has wine in stock. He basically sits and fishes in the VIP area every time. The VIP area has more hidden monitoring. The police tuned out all the surveillance videos of Meng Handong’s consumption in the last 3 months and found out that there were two simultaneous appearances in the period of one and a half months to one month before Meng Handong’s death. Meng Handong took the initiative to kiss him. I passed Chen Jia, once on the sofa, and once stood in the corridor next to him. They were very obsessed with each other, but it was not Chen Jia who Meng Handong took away that night.

The expressions of the people in the conference room are simply brilliant, Qin Lili has a gossip expression, and she can't wait to follow up and ask.

Qi Chuchen thought about it, "According to the interview, Chen Jia is not Lu Zhongyan, and Meng Handong’s playmate is very low in the circles we have visited. So can we think: Chen Jia and Lu Zhongyan are dealing with emotional relations? , Meng Handong is very different. He “can’t play” and we visited a group whose ideal goal is to make friends. So when it comes to Meng Handong, Lu Zhongyan can say something, but he doesn’t have a deep understanding of Chen Jia, then Can we try to find some people in this circle who are hidden underneath, who are unwilling to reveal their orientation, their relationship partners are more stable, or those who don’t like to play or can’t play with others to see if anyone knows Chen? Jia? Especially the people who are the same as Chen Jia’s hometown, whose social circles may overlap in the past, are older than Chen Jia. Such people should not be in the groups and forums that Chen Jia currently has in our investigation. There is also a kind of people who are born in the circle of play, but who do not play but have the information source." Qi Chuchen summed up everyone's progress just now and put forward a new direction.

For a while, everyone in the conference room was lost in thought, where to find such a hidden person?

"The founder of a well-known GAY bar in Fengqi City that has been open for more than five years, the owner of this type of bar in Chen Jia's hometown of Minyang County, and the older local normal and healthy hobby and dating group owner." Zhu Zhen is next to him. Said something.

"Next, we are going to sort out the big and small GAY bars in this city. Founders who have opened more than 3 years, people who have opened such bars five years ago in Minyang County, and highly active people over 30 years old in Minyang County. The person in charge of the dating group screened out the social overlaps with Chen Jia, and once again checked Chen Jia’s social relations in Minyang, focusing on the special orientation. If possible, dig out all the same-sex he has contacted. Gao Rui is responsible Fengqi’s, Luo Hao, and Zhu Zhen are in charge of Minyang. The others continue to work as previously arranged. The hospital must keep an eye on it. You can arrange for the shift. If Mo Feng wakes up, notify me immediately! There is also monitoring that Lu Zhongyan is missing. Mobile phone, and Chen Jia’s communication tool will continue to follow. We will meet again at nine in the morning. If you have any ideas or ideas in the middle, you can directly talk to me. Now everyone is working.” Zhang Chao arranged the work and waved to everyone. Disbanded.

Everyone walked out of the meeting room one after another. Qi Chuchen did not leave. Zhang Chao went to Qi Chuchen and opened a chair and sat down. He took out a cigarette and threw it to Qi Chuchen, leaving Qi Chuchen absent two days ago. Their investigation The work again gave Qi Chuchen a few key points:

During the independent investigation by the following two brigades, all the social intersections on Lu Zhongyan’s side were circling, flirting, making appointments, being rejected, making appointments successfully, and continuing to make appointments. Even if 1,000 of them were dug out, they could not escape these states. The account of the victim's room reservation was stolen, and the clue of the person who booked the room could not be traced.

The second victim, Meng Handong, could not find any clues besides making appointments. He felt that these two irritable stallions died in different breeding grounds, far apart, and the method of death was very different. . Looking at their dates after putting them together, they found that there are many intersections. Except for the appointments, there is no appointment except Chen Jia and others on the surface.

Zhang Chao took the lead and secretly checked a few people from these dates. In these intersections, apart from Chen Jia, others appeared again, either working, studying, or continuing to make appointments. Only when Chen Jia disappeared, there was no news. It was very abnormal to see Chen Jia deliberately show his face before the two deceased were alive.

Qi Chuchen took the lighter and lit it, took a long breath and spit it out.

"The connection is too thin! No DNA was found on the first victim, Lu Zhongyan, and his clothes and mobile phones were taken away; the second victim, Meng Handong, had DNA in his nails, but it was not in our database; the third victim, Mo Feng Now half-dead, the connection between these three is too thin, it looks like it will be broken if it can't be stretched, we must now pick out the shadow of Chen Jia, make it concrete, and make it plump!"

"It seems that the victims of the three independent cases happen to be of the same sex, and they all happen to be relatively open. The circle is not likely to happen to have an appointment with Chen Jia. But since I have applied for the case of Lu Zhongyan and Meng Handong, I I think the two people must have a potential relationship. There are so many coincidences. Chen Jia is not a lone star, and he has no appointment with him to die? Impossible! Even if it is not Chen Jia, it has something to do with their circle. People. It’s just that we haven’t investigated enough, so there’s a lot of fog." Zhang Chao took a bit of a cigarette.

"Lu Zhongyan and Meng Handong must have come down at once, even if it is my intuition for handling the case for so many years. There is no perfect crime. Lu Zhongyan died like that, but the clues are too clean. I feel that the fog behind him is the key! If you can find it The DNA comparison of Chen Jia’s biological samples may make it faster to determine whether Chen Jia is related. Only then can we analyze where he is hiding and will continue to commit crimes? In other words, if it’s not for Chen Jia, then we will be around today. Chen Jia’s investigation is invalidated, and the rest will have to be repeated! And it will be more difficult because this person hides deeper.” Qi Chuchen pushed off the cigarette **** in his hand, stood up and patted the scattered soot on his body, preparing to go to the office. .

"I have a spare machine. Take it and use it first. The instant messaging is also installed in it. Go back and buy it when it's empty. It just so happens that this new model will be on the market." Zhang Chao wiped out the cigarette butts and walked out of the meeting room together. .

"it is good!"

Back at the office, Zhang Chao took out the mobile phone from the drawer and threw it to Qi Chuchen. Qi Chuchen hurriedly let the 300 ringing phones lie in the drawer. Installed the phone card, boarded the instant messenger, opened the text message, wanted to send a message to Yan Mu, and looked at the white sky outside the window: Is he still asleep? Immediately locked the phone and walked to Gao Rui to help Gao Rui sort out the information.

In the office, apart from the sound of crackling keyboards, there are soft whispers from time to time. Several sets of LED tubes illuminate the entire office like daytime, as if night has never fallen here.

At nine o'clock in the morning, Zhang Chao's office was white and foggy.

Luo Hao first introduced the information screened with Zhu Zhen. “Based on the ideas at the meeting, we found that we are still in Minyang and there are 3 eligible men. One is the veterinary pet shop owner Da Chen Jia, who was three years old, and Chen Jia was the same in high school. A teacher in charge of a class, the emotional orientation of that teacher is also a bit unclear." After saying this, Luo Hao turned his head and looked at Zhang Chao and Qi Chuchen, and they met each other without saying a word.

Luo Hao continued: "Now there is no GAY in Minyang. The only one that has been opened earlier has not been open for long. The area of ​​Minyang is small and it will be relatively conservative, so the customer base is very small. Going down, this boss has opened an e-sports game-themed internet cafe in Minyang. There is also an outdoor game organizer who organizes outdoor activities many years ago. After looking up the previous information, his boyfriend is looking for it in the outdoor circle. Yes, Chen Jia used to be more active in his self-built forum and participated in several outdoor activities organized by him."

"Chu Chen and I screened the situation in this city. There are currently three popular bars in the circle. The founders are all about 35 years old. They have been open for six or seven years. If you count the elderly in this circle, there are two other bars last year. , The previous year or transfer or closure, the boss went abroad. Many others have been opened for less than 3 years, and the bosses are young people in their early 20s." Gao Rui went on to talk about his own situation.

"Luo Hao, Zhu Zhen, you are now leaving for Minyang, and strive to see all three of you today, and we will continue to meet when you come back tonight. Chu Chen Gao Rui, you two will go to the Second People's Hospital with me." Zhang Chao arranged After that, put on the coat and go out with a few people.

"Boss, give me the keys to get the car." Gao Rui asked Zhang Chao to take the car keys and hurried downstairs.

"Who did you go to Xinjiang with?" Zhang Chao and Qi Chuchen walked behind and asked quietly.

Qi Chuchen hesitated, "I went there alone... I met a Fengqi who passed by in Xinjiang and walked with him."

"Um~~" Zhang Chao nodded thoughtfully.

Mo Feng arranged it in the intensive care unit on the top floor, next to the doctor's office and the nurse's station. Three policemen stood guard at the door and saw Zhang Chao coming, and immediately got up: "Team Zhang, Brother Qi, Brother Rui."

"Have you been awake?" Zhang Chao asked.

Qi Chuchen looked at the man lying on the hospital bed from a distance through the glass. The bedside is full of various instruments, covering most of his body. The curtain was half pulled, and his face couldn't be seen clearly.
