Huang Ying took Han Chaoyang's dirty clothes and left with Xie Lingling, and Han Chaoyang returned to the operation area and told Wu Wei about taking half a day off tomorrow.

"If you should ask for leave, you must participate in such an important ceremony, so call Tengda." ”

"You can't leave people here, and as soon as I leave, you can only stare here tomorrow morning, and you can't do anything else. ”

Wu Wei had just thought about what he was going to do tomorrow morning, and he didn't want Han Chaoyang to go. At the same time, I know very well that the person next to me who participated in the appointment ceremony of PolyU is not only his personal business, but also the business of the sub-bureau. It can be said that his acceptance of PolyU's invitation as a distinguished lecturer at the PolyU School of Art to assist PolyU in building a high-level orchestra is a prerequisite for helping the Xinyuan Police Station to "co-opt" the PolyU Guard and form the Yanyang University of Science and Technology Volunteer Security Patrol Team.

It is very important to solve the case, but the murder case in front of me is the case of the high-tech district bureau, and the affairs of your own unit are obviously more important than the affairs of other units.

Wu Wei still has this "overall situation", and smiled casually: "It doesn't matter, anyway, we are not the main force in solving the case, and the leaders of the task force don't expect us to play any role at all." Moreover, the circumstances we are looking into are all based on baseless speculation. There is only the possibility of pranks, but this is extremely unlikely. ”

"I thought so too, but fortunately I didn't report it directly to Tengda, otherwise I don't know what jokes would have been made. ”

"Call Tengda first to ask for leave, and then Tengda will rest later. ”

"Okay, it's too noisy inside, I'll go out and fight. ”

……

As soon as it gets dark, there are no people in the steel wholesale market, there are few cars on the road outside, and the project headquarters on the third floor of the Yuanfeng Hotel is still brightly lit.

The investigation of the case has reached an impasse, and Teng Jiming has not slept well for two days and two nights, and now he can't sleep either. was half-leaning back in the chair, staring at a photo posted on the white blackboard, smoking a cigarette while listening to the criminal policeman Xiao Liu's report on the feedback from each group.

"The video analysis team repeatedly reviewed the 27 traffic, public security and civil surveillance videos around the sand and gravel plant from 10 p.m. on the 15th to 12 noon on the 18th, and found a total of 461 trucks, vans, cars, motor three-wheelers and electric three-wheelers that may be used to transport corpses, because some of the surveillance cameras are not high-definition, only the license plate numbers of 184 of the motor vehicles are ......"

The autopsy results showed that the victim was killed at night, and the murderer would not choose a crowded daylight when throwing the body.

There are few surveillance cameras in this area, and the light is not good at night, and the video taken is not clear, so it is difficult to lock the suspect through surveillance.

Teng Jiming didn't have much hope for this, raised his arm to knock the cigarette ash, and asked in a hoarse voice: "How are the victim's mobile phone call records checked?"

"The three mobile phone numbers we have are all used by the victim before he came to Yanyang. A total of 132 contacts were counted, excluding those advertising and sales, telecommunications fraud, hotels, song halls and food delivery calls, only 12 of them really contacted the victims more frequently, and all of them were from Kaijing County. The team, with the assistance of the Kaijing County Public Security Bureau, has found 10 of them, and two others are missing. ”

The leader also ran outside for a day, and just came back before dinner, so he didn't know much about these situations.

Xiao Liu glanced down at the record and continued to report: "One of the two people who have not been contacted for the time being is named Zhou Zhongjie, 24 years old this year, with a criminal record, he was sentenced to three years in prison on suspicion of theft and intentional injury, and was released from prison in September last year.

The team found his family, and his parents said that he had gone to the south to work in March this year and had not contacted his family since he left. Several other people who often fooled around with Cao Shengkai before also confirmed that Zhou Zhongjie went out to work before Cao Shengkai came to Yanyang, and after he went out, before Cao Shengkai came to Yanyang, he had not heard of the two having contact. ”

Teng Jiming took the photo and glanced at it, and asked, "What's the other one?"

"The other surnamed Wei, named Wei Xiaojun, is the same age as the victim, was a classmate of the victim when he was in middle school, was expelled from school for fighting with the victim, and has been idle in the county seat since then. During the Spring Festival this year, his cousin took him to work at a construction site in the East China Sea, but he was so tired that he ran away after working at the construction site for less than a month, and he has not contacted his family until now. ”

There are all kinds of indications that these two guys should have nothing to do with Cao Shengkai's death, but they still have to be investigated.

Teng Jiming snuffed out his cigarette butt, turned around and said: "Luo Zhi, I went to several business halls of CCB today to check the surveillance, and found that he went to the counter to deposit money alone, and he didn't look flustered. At least on the surface, it doesn't look like engaging in drug crimes. ”

"The two bank cards are reserved for all the previous mobile phone numbers?"

"All before coming to Yanyang, in fact, these two cards were also done in my hometown. Teng Jiming paused, and then said: "When I applied for ICBC's debit card, he opened online banking and mobile banking, but he never used it, and he didn't use it much for mobile payment. Judging from the bank's transaction records, he often swiped his card to make purchases and occasionally went to the ATM to withdraw money. ”

This Cao Shengkai is not not in fashion, but has been living in a small county before, and the mobile payment application in the small county town is not as wide as in the provincial capital. Once you've made it a habit to make purchases with your card and cash, it will take a while before you can accept mobile payments.

It is difficult to find out the eyebrows through the line of money, and Deputy Detachment Leader Luo muttered: "What about the hotels where he stayed?"

"Lao Zhu is checking, there are a lot of accommodation records, but the surveillance video of many hotels is only stored for a month or even less, and from the few videos he saw, he is staying alone. ”

"People are social animals, and he has a group of people fooling around with him in his hometown, why did he become so low-key when he arrived in Yanyang, no matter where he went, he was alone, sneaky, what the hell was he doing?"

"He's certainly not alone. Teng Jiming took out a hotel accommodation record from the folder, stared at the time and date on it, and said with a frown: "I have been in Yanyang for a few months, and I only stayed in a hotel for 26 days. ”

As he was talking, his phone rang suddenly.

Looking at the caller ID, Teng Jiming was really a little excited, and hurriedly pressed the call button.

"Comrade Han Chaoyang, did you sift out something?"

"The report is huge, today is about the same as yesterday, and no valuable clues have been screened out. ”

Didn't sift out valuable clues to make a call!

Teng Jiming's face was already not good-looking, but now it became more ugly, holding his mobile phone tightly and asking coldly, "What's the matter?"

"The Polytechnic University will hold an appointment ceremony for chair professors and distinguished lecturers tomorrow morning, and I promised that the university leaders would accept the appointment and concurrently serve as a distinguished lecturer of the PolyU School of Arts. I was informed by the school that I would attend the appointment ceremony tomorrow morning and that I would like to take a half-day off. ”

Are the community police very idle, what kind of part-time work they do!

If it was the police of the High-tech District Bureau who was transferred to the task force to make this call, Teng Jiming would not only not agree, but would also criticize him, but the young man on the other end of the phone was not a police officer of the High-tech District Bureau, and he said it very clearly, and the leaders of their Yandong Branch knew everything.

Anyway, there are two policemen in the Yandong Branch in the sand and gravel factory, as long as one policeman is watching the scene.

In fact, there is no need to arrange for the police to keep an eye on the sifting sand, just arrange two auxiliary police, the main reason is that their stone bureau is too inauthentic, and the body was obviously found in their jurisdiction, but it was actually pushed away, what is this not prevarication?

"Since the ceremony is important, let's go to it, go early and come back early. ”

"Yes, thank you. ”

"I still have some things, hang up first. ”

Han Chaoyang really mustered up the courage to make this call, put down the phone and smiled with relief: "Finally asked for leave, Angkor, I'll be watching at night, you go and rest." ”

"It's okay, I'll keep an eye on it, you have to attend the appointment ceremony tomorrow, and if you don't sleep now, you will definitely be listless by then." You represent not only yourself, but also our Fa Yuen Street Police Station and even the Yandong Branch, and you must nurture your spirits and don't let PolyU leaders and PolyU teachers and students see the jokes of our Branch. ”
