Mystery Case Tracing [Criminal Investigation]

I have been spinning for too long recently, and I haven't eaten a serious meal for a long time. Qi Chuchen felt that this meal might be the most fragrant meal he had eaten in the past few years. It was so fragrant that he couldn't bear to open his mouth too much. He took a small bite to fully taste the taste of the food. If an inappropriate adjective is used for this meal, it would be: the marrow knows the taste!

After a meal was finally finished, Qi Chuchen took the lunch box and went out to wash it cleanly. When he came back, he took a napkin and wiped all the drops of water. Then he took a picture together, opened WeChat and sent it out.

"It's all done, the cooking is good, keep working hard."

"If you still want to eat, just put the lunch box in your duty room, and I will get it empty when I turn around." Yan Mu replied.

Just as Qi Chuchen wanted to continue typing, the phone rang untimely.

"Chen Jia may be following me." Luo Zheyu's slightly hesitant voice came from the other end of the phone.

"Where are you now?" Qi Chuchen asked.

"Office, I'll come to work overtime." Luo Zheyu said.

"I'll come over right away, you stay in the office and wait for me." Qi Chuchen hung up the phone and went to Zhang Chao's office.

"Luo Zheyu called again and said that he might be followed by Chen Jia. I'll see what's going on first." Zhang Chao nodded, "Be careful. Let him find a place that is convenient for monitoring to live temporarily."

Qi Chuchen called Gao Rui to leave, walked to the door of the office, remembered something, hurried back to his office, put a thermal bag with a lunch box on it, and left again.

After going downstairs, Qi Chuchen didn't get in the car directly. He first walked to the duty room and handed the bag to the staff on duty in the guard room: "Leave this thing, and someone should come to pick it up later."

The concierge took a note and wrote: Officer Qi's belongings, wait for someone to fetch it. Put it up, lift it up, and put it on the shelf next to the wall.

Gao Rui drove the car to the door of the guard room, Qi Chuchen got on the co-driver and set off for the Cultural Creative Science Park together.

When we arrived at Luo Zheyu's 26th floor office, the door was open and Luo Zheyu was sitting in a large office chair in a daze. Seeing Qi Chuchen and the others coming in, they stood up and beckoned, leading them to the floor-to-ceiling glass on the side of the office. He raised his finger to the road far away outside the window,

"He was standing there just now, looking at me. I don't know how long he was there. After he found out that I saw him, he left soon."

"About what time, specific location?" Qi Chuchen took out his mobile phone. Start dialing.

Luo Zheyu looked at the phone call log, "It's past seven o'clock, right under the street light."

"You go to the side of Luo Zheyu's office building and go out along this road. Go to the left side of the road opposite the car access road at the park gate, and cross the road until there is a street light on the opposite side that is directly facing the sight of the office on the 26th floor. You pass now, and I stand In front of the office window, you can see me when you are here. If you stand right, I will give you a gesture. If you stand wrong, you will move left and right according to my gesture.”

Five minutes later, the two plainclothes ran to the place Qi Chuchen told him on the phone. Standing under the street lamp, they looked back and saw Qi Chuchen three people standing in front of the window on the 26th floor.

Qi Chuchen turned his head and asked Luo Zheyu: "Is this the position?"

Luo Zheyu nodded, Qi Chuchen raised his right hand above his head, thumbs up, the other four fingers clenched fists, and gestured at two plainclothes. The two plainclothes returned a gesture and bury their heads looking around on the ground. After a while, he put on his gloves, took out the evidence bag he carried with him, picked up something from the ground and put it into the evidence bag. After putting it away, call Qi Chuchen,

"I found a white cigarette butt, go back to the laboratory."

"Okay, you take it back first, here are me and Gao Rui, we will contact you later." Qi Chuchen confessed his plainclothes.

"Are you still working overtime?" Qi Chuchen turned to ask Luo Zheyu.

"You don't need to add it." Luo Zheyu's voice sounded a little helpless.

"You come home with me, my community is convenient for our people to follow. You live in my house these days, and I will pick you up when you go to get off work and work. If there is nothing else, you'd better stay at my home and company." Qi Chuchen Without waiting for Luo Zheyu's response, he took out his cell phone, sent a text message to the two plainclothes just now, told them an address, and went back to hand in things to this address to wait for the arrangement.

Luo Zheyu walked to a set of wooden cabinets against the wall in the office, opened it, took out a handbag from it, put a few clothes in it, and said, "Let's go." He followed Qi Chuchen and Gao Rui went downstairs. , Got into the car and returned to Qi Chuchen's house.

Qi Chuchen's home is a two-bedroom, two-living room, located close to the city center, not far from the city bureau, and going to Luo Zheyu Company is not a detour. Qi Chuchen's life is simple, and there are only a few places for activities at home. The second bedroom is basically unoccupied, and the furniture and bedding are almost brand new.

Qi Chuchen led Luo Zheyu home and opened the second bedroom: "Thank you for a few days here. Chen Jia has caught it, and you will be free. We don't want to make any more trouble, I hope you cooperate." Take out a set of towels, bath towels and toothbrushes from the locker.

"Brother, you have all these things so good, do you often take people home overnight?" Gao Rui looked beside him with surprise. The people and things he has come into contact with in the past few days have rubbed him so that it is very normal for everyone around him to do something that conflicts with his image.

"Go to your uncle, this is from the mall for events and the credit card center. You didn't see the logo on it." Qi Chuchen glared at Gao Rui.

The two plainclothes quickly arrived at Qi Chuchen’s home complex. Qi Chuchen confessed to Luo Zheyu. Before going out, he took out a bunch of keys from the upper drawer of the shoe cabinet at the door and threw it to Luo Zheyu, then went downstairs and came to watch. The two plainclothes confessed a few words, and then went back to the city bureau with Gao Rui.

The DNA test of the cigarette butts brought back by plainclothes the next morning was completed, and the DNA samples in Meng Handong's nails were the same as those found in Luo Zheyu's family.

In the next few days, Qi Chuchen drove from the city bureau to his home at 8 o'clock every morning, picked up Luo Zheyu and sent him to the company, and then picked him up from his home according to Luo Zheyu's work schedule every night, and then returned to the city bureau to work overtime.

After the technical team worked overtime to make the gait analysis, the monitoring of each bar was extracted and a part of the consistent production was extracted and part was given to Zhang Chao and the others. Everyone was spinning around with different surveillance videos for a few days.

After boiling countless pairs of eyes, Chen Jia's whereabouts for these two or three months finally surfaced slowly.

From the beginning of June, Chen Jia wore different styles of women's clothing. Roughly speaking, there were more than one set. He began to appear in seven popular bars in the circle. He would go to 1-2 stores almost every day, and when he repeated the next day. It will stagger the previous time period, and sometimes reappear at the same bar two or three hours apart, but usually change the wig and change the makeup; among them is the rainbow club that Qi Chuchen and the others have been to twice. Two of these seven bars are frequently visited by Lu Zhongyan. The first time he appeared in women’s clothing, he successfully attracted Lu Zhongyan’s attention. After receiving Lu Zhongyan’s attention, Chen Jia began to reduce the appearance of the bars in Lu Zhongyan. During this period, he changed back. Men's clothing, appeared in the bar where Meng Handong appeared, and had the first direct contact with Meng Handong. It wasn't until 3 days before Lu Zhongyan's death that Chen Jia again appeared in Lu Zhongyan's line of sight while wearing women's clothing, and then disappeared. Then he disappeared for a week or so. Men's clothing appeared in the bar frequently visited by Meng Handong, and had a second contact with Meng Handong. Five days later, Meng Handong was killed. Before and after Meng Handong's murder, Chen Jia went to the bars frequently visited by Mo Feng with her women's clothing. Most of the time, it was after ten o'clock in the evening. He went in for a circle and left after an hour and a half, as if looking for someone.

At two o'clock in the morning, the meeting room on the third floor of the Municipal Bureau. In the past few days, in everyone's eyes, every frame of impressions in the surveillance video that has been passed through countless times in their minds has finally converged into a clear and captureable line.

Zhang Chao wrote on the whiteboard: A, Lu Zhongyan, B, Meng Handong, C and Mo Feng. Everyone knows that these three letters represent the bar where Chen Jia and the three victims were in frontal contact. Among the pictures that could not be captured by the surveillance system. Outside, Chen Jia used a special way to go to the crime scene with them.

Zhang Chao wrote on the other side of the blackboard, D, E, F, G, and a big question mark was drawn underneath. This is asking everyone, including Zhang Chao himself, which of these bars will Chen Jia take away from the next person, and what characteristics this person might have?

"In the video of the last few days, Chen Jia started to appear in these bars once or twice in women's clothing. He never appeared in the three bars where the victim was frequented after the victim died. Everyone can talk about what they think."

"Stupidly, we don't have a lot of things in our team, just a lot of masters, and we mix into various bars under the disguise." Zhu Zhen said.

Zhang Chao nodded.

"The four bars don’t have so many manpower for deployment. You can select and take turns. Each night, two focus on deployment. The other two arrange people to stay behind and provide support. Then there is no situation. After the business ends, take the surveillance video to come back and watch. "Luo Hao said.

Zhang Chao nodded again.

"These bars are densely staffed. Chen Jia's appearance is usually during the busiest business hours. If you do something in the bar, it may hurt the innocent and it is more difficult. I also tend to pretend to trap." Another individual said.

Zhang Chao had an expression of comfort.

"There are only three, and I suggest to cross the rainbow. The three bars that Chen Jia chose before were all rather sluggish, and there were not much monitoring in ordinary areas, so it was convenient for Chen Jia to contact the victims. The rainbow atmosphere is relatively high-end, not as high as other bars, and it is not easy to rush Being dizzy and monitoring a lot is not conducive for Chen Jia to stir up the victim's emotions." Qi Chuchen pointed to the blackboard.

"Any other considerations?" Zhang Chao held the pen without moving, looking at Qi Chuchen

Qi Chuchen looked at the whiteboard calmly, not knowing whether he was thinking or phrasing at the moment.
