Chapter 265

Xu Dayuan coughed, and Zhang Niannian realized that he was a bit outrageous, so he quickly smiled and waved his hands.

"I'm emotional, I'm serious. After the incident, we checked the surveillance cameras around the deceased's house. At 5:11 on the evening of May 21, Zhang Wei drove out in his van, drove around a few times, and returned to the deceased. His sister Xia Lihua called.

I don't know if it was because Xia Lihua was worried. He didn't say anything about Xia Limin not coming home. He just asked a few casual questions and then hung up the phone. Then he went out again after 23:00, but this time it didn't take long. If we need this monitoring, we also keep it and provide it. "

Xu Dayuan shook his head, this surveillance is meaningless.

"Have you checked Zhang Wei's cell phone?"

Zhang Sannian nodded.

"When we found the deceased, we listed Zhang Wei as a suspect for investigation. However, Zhang Wei's reaction was that he was deeply saddened and his mood was very unstable. He never admitted that the body was Xia Limin. Until Xia Lihua and Xia Limin made a DNA comparison, he to accept the result.”

Xu Dayuan turned the pen in his hand and drew a circle on Zhang Wei's name.

Indeed, in general such cases, the spouse will be listed as the first suspect. After all, the fact is the same. According to the statistics of the United Nations in 2011, in the murder cases of women, 58% of the murderers are family members, and 34% of the murderers are husbands or boyfriends (including former and current).

Maybe the reality is cruel, but this is the reality, the closest person may be the biggest threat to your life.

"Do you have Zhang Wei's information here? Information about work and life before and after marriage, and Zhang Wei's status after the case happened. Is there any relevant investigation on these?"

Zhang Niannian looked a little embarrassed, and quickly opened the notebook and said.

"There is no relevant information added to the dossier, but some can be found on the household registration. We have also done related investigations before, but after excluding sexual suspicion, the relevant content was removed.

Zhang Wei, born on February 1980, 2, is 12 years old. Before marrying Xia Limin, he had a marriage once. He had a pair of children, five and three years old, who were raised by his ex-wife.

房子还有存款也都给了前妻，在2010年9月29日办理的离婚，与死者夏丽敏是在2010年12月3日领证的，二人没有办婚礼。

Xia Limin's elder sister did not object to this point. After all, her younger sister has such a temperament, she felt that there was no wedding, and if they broke up later, it would be easier to talk about it.

As for work, Zhang Wei used to work in a law firm, but because he guarantied for his colleague Li Xin and was suspected of interfering with the normal progress of litigation and arbitration activities, he was burdened with high debts, lost his job, and was revoked his lawyer's license .

But he still has commercial housing, and now he opened an Internet cafe. The Internet cafe is currently in operation, but the benefits are not particularly good. Xia Lihua said that Zhang Wei is very good to Xia Limin. He buys whatever he wants, mobile phones, cosmetics and clothes, all for her. the best. "

Seeing that Zhang Sannian stopped, Xu Dayuan knew that their investigation was limited to all Zhang Wei's experiences before Xia Limin's death, but according to this investigation, Zhang Wei seemed to be very kind to Xia Limin.

"Zhang Wei doesn't know about Chang Yuzhang's existence, does he?"

Everyone fell silent. After all, Chang Yuzhang's investigation was done by Tao Zhenshan in the morning, and Zhang Niannian didn't pay much attention to Chang Yuzhang, so Xu Dayuan waved his hand.

"Okay, let's go here for the first project meeting. Captain Zhang is here to investigate all Zhang Wei's information. Whether it is useful or not, I want to know all his information, and whether he knows Chang Yuzhang? Do you know Xia Li?" The relationship between Min and Chang Yuzhang?"

Zhang Niannian got up with an embarrassed expression on his face, but his eyes were very firm. It seemed that after Xu Dayuan said so, he also found some direction and stopped bumping around like headless chickens as before.

"Xu Bureau, I will investigate now, and report as soon as I have any news."

Zhang Sannian took people away, and Xu Dayuan waved his hands at Xiao Zeng and Liu Yufei, signaling them to follow. They were not hypocritical, after all, they came here to solve the case, and after this case, none of them attended the meeting. , even the dossier Xu Dayuan didn't let him touch it.

Xu Dayuan raised his chin towards Xiao Bai.

"Call Lao Tao, hasn't he brought it back after so long?"

Bai Ruixin hurriedly dialed Tao Zhenshan's phone, turned on the speakerphone, and the other party connected. As soon as Xiaobai gave a hello, Tao Zhenshan interrupted him and said:

"Tell the leader, don't rush us. We've already reached the gate. Come down and go to the interrogation room. I brought him from the insurance company and he's signing a contract. I kindly waited for him for 3 minutes."

Liu Yongxin lowered his head slightly, covering his nose with his hands and suppressing a smile. Xu Dayuan forced these people too hard, and he knew it was Xu Dayuan's arrangement when they answered the phone one by one. Now it is straightforward enough, don't ask me, I will explain to the head office Come on!

Xu Dayuan stood up, and Liu Yongxin poked Zhou Ning's arm.

Zhou Ning sighed, what do you mean?

Holding the notebook between his hands, Xu Dayuan quickly walked over to Zhou Ning, patted him on the shoulder, and glanced at Xiaoqu again.

"Don't dawdle, we are all in the working group. Director Zhou followed me to watch the trial. Xiaoqu will temporarily install a monitoring system in the interrogation room, which is to use the fourth-phase function that you experimented with."

Zhou Ning paused, when did the fourth issue come out, why didn't he know?
Seeing Zhou Ning's expression, Xu Dayuan instantly felt comfortable.

"Zhou Xiaozhou, you really don't care about Dr. Lu. You proposed the fourth phase. He has already taken shape. What does it mean that you don't know how to start collecting data and conducting experiments?"

Zhou Ning scratched his head.

"Leader, I don't think you need me to help you stand in the observation room. After all, this is not the city bureau, and there may not be an observation room."

Xu Dayuan raised his hand to stop Zhou Ning's remaining words.

"Don't worry, you must have it!"

The few people didn't say any more, they walked downstairs quickly, the accompanying criminal police hurriedly swiped their cards, and the few people followed this person to the next door to the interrogation room. Sure enough, there is an observation room here, and the conditions are not worse than those of the Municipal Bureau, Xu Dayuan tsk With a sound.

"It looks like it has just been renovated. The walls inside are all soft, and there are surveillance cameras at all four corners. Have you finished Xiaoqu?"

Xiao Qu clattered on the computer, and when Xu Dayuan asked, he stopped for the last time. A surveillance camera was facing the interrogation chair. Judging from the angle, it should be pasted next to the one-sided glass.

Da Zhao leaned over and took a closer look, but found nothing special.

"This thing can be combined with the application of the fourth phase. I don't see any difference from ordinary surveillance?"

Xiao Qu waved his hand in disgust.

"What do you know, there is no one sitting here, and this data collection requires comparative data. Xu Dayi will go in, and you can ask questions such as name, age, work unit, home address, etc., and you will know it at a glance. True and false information must be interspersed with true and false information.

I will collect and analyze the data first, and then you ask, whether he told the truth or concealed something, the software can analyze it for you, and the notebook on the table inside is a prompter, you can see what I gave The hint, and that sentence is a lie. "

Xu Dayuan became interested, rolled up his arms and sleeves, and waved at Xiaobai.

"Come on, you come in with me for interrogation, what does the prompt look like?"

Xiaoqu turned to a picture on her mobile phone and held it in front of Xu Dayuan and Zhou Ning. On it was a red frame with a sentence inside, and the problematic parts were drawn out by green wavy lines.

Zhou Ning almost choked on this color scheme, but it is indeed red and green, which is really eye-catching. Xu Dayuan nodded in satisfaction, and quickly walked to the next door.

Tao Zhenshan had already brought him in, and Chang Yuzhang was handcuffed to a chair. He suddenly lost his previous indifference. Although he had been to the police station before, it was just to take notes, and the walls of such a closed room were still blue. The upholstered, handcuffed seat, and the three policemen staring at him, made his eyes wander.

Obviously, the kid panicked.

Xu Dayuan knocked on the table with his pen, and Chang Yuzhang quickly set his eyes on Xu Dayuan.

"Do you know where this is?"

"Public Security Bureau."

Xu Dayuan shook his head.

"Inaccurate, this is Rudong City Criminal Police Brigade, and we are policemen from Qindao City Criminal Police Detachment, since I called you here, I think you know what's going on, and you know the procedures, come on and be yourself Introduce, starting from name, gender, age, to home address and work unit, one by one."

Chang Yuzhang nodded, swallowed a mouthful of saliva, seemed to be trying to calm himself down, and then said slowly:

"My name is Chang Yuzhang, male, I am 25 years old, and I am from Rudong City. My family lives in Unit 12, Building 12, Changle Garden, No. 302 Yuehu North Road, and my workplace is Rudong Branch of Cathay Insurance Company."

Xu Dayuan raised his eyebrows.

"Do you know Xia Limin?"

"know."

There was a loud snap, and Chang Yuzhang trembled from the sudden movement, and raised his hand unconsciously, but the handcuffs restricted his movements.

"Let me tell you, I have a bad temper and I don't have much patience. We are cleaning up the backlog of cases and we are very busy with work. If you ask what you know, just say it yourself. Don't ask a question and nod, or just answer if you know or not. Yes. Yet?
Just like I asked you, do you know Xia Limin?Just answer me directly, how did you know each other, what is the relationship, answer it yourself, understand? "

Chang Yuzhang nodded vigorously, and seemed to feel that his actions did not meet Xu Dayuan's requirements, so he quickly waved his hands and said quickly:
"We know each other. We are classmates in high school. My birthday is small, and I study for a year at night. We used to be boyfriend and girlfriend, it's that simple."

Right after these few words were exited, on the computer in front of Xiao Qu and Xu Dayuan, a red dialog box popped up, in which the last half of the sentence was marked with green wavy lines, which kept flickering.

With this brightness, it looked like a marquee in a night show, Xu Dayuan's eyelids twitched and he pressed down on the screen.

Da Zhao couldn't hold back his laughter, he punched Xiao Qu's shoulder with his fist, and couldn't stand the laughter anymore.

"Don't tell me Xiaoqu, this reminder was designed by you, it blinded my 24K eyes, as long as there is a reminder, what are you doing with such a night scene like a marquee? Hahahaha!"

Xiao Qu gave him a blank look, but he didn't refute. After all, he also felt that he was a bit thrown, so he quickly looked at the picture of Chang Yuzhang.

He stood up and walked to Chang Yuzhang's side.

"Former boyfriend and girlfriend?"

Chang Yuzhang nodded.

"Well, I went to bed!"
