Chapter 266 Why Did He Kill Her?
Xu Dayuan stared into Chang Yuzhang's eyes without blinking.

What he asked was his former boyfriend and girlfriend?
And the answer Chang Yuzhang gave was that he had slept.

It seems that he answered Xu Dayuan's question, but this answer means that he is denying that they are boyfriend and girlfriend, at least Chang Yuzhang unilaterally does not think that they are boyfriend and girlfriend, more like sex.

After all, they met so frequently at the Golden Harvest Hotel, and after thinking about it, it really fits this answer.

"On May 2011, 5, when did you leave work? When did you get home?"

"I don't remember, it was a bit late when I got off work, I had dinner with a client, and then I went home."

The marquee behind Xu Dayuan began to flicker, Zhou Ning raised his forehead and raised his hand to block Xiaoqu's direction. After all, in the dark, Xiaoqu's computer is more dazzling, and the atmosphere is directly full.

Xu Dayuan was not impatient, folded his arms, and asked:

"Let's change the question. Did Xia Limin give you a phone card, and this phone card was used by you for unilateral contact. Is there such a thing?"

Chang Yuzhang nodded, and didn't say yes this time, but Xu Dayuan didn't hesitate, and quickly asked:
"Did you see Xia Limin that day?"

"No."

Chang Yuzhang shook his head without even thinking about it, Xu Dayuan stretched out his hand towards Xiaobai, Bai Ruixin hurriedly hugged the notebook, moved closer, and thoughtfully found the surveillance screen processed by Xiaoqu.

Of course, the interception has been done, seeing the surveillance, especially in the surveillance, the moment he turned his head, the intercepted video enlarged his face, followed by a comparison picture, Chang Yuzhang looked at Xu Dayuan in a daze, obviously this operation Let him be a little overwhelmed.

Xu Dayuan was patient, pointed the notebook to Chang Yuzhang, and patiently explained:

"Don't worry, let me introduce it to you. This is a software developed by our city bureau and Qindao University. It can process blurred videos clearly, and can also collect the features of faces in the screen, and then compare them. See below Is it marked, the match rate is 100%, you can check the time again!"

Following the direction of Xu Dayuan's finger, Chang Yuzhang saw the time displayed on the monitor. After the monitor was played, all the models and numbers were typed out next to it, along with the information on the driving license. Chang Yuzhang just stared at the screen for a long time. There are 5 minutes.

Zhou Ning knew that he was thinking of countermeasures, but the facts were in front of him, and there was nothing to quibble about at this moment.

After a long silence, Chang Yuzhang closed his eyes and said:
"I've seen her. I've seen her the night Xia Limin died. I don't want to be entangled with her anymore. She's married and her husband is good to her, but she just clings to me and threatens me.

Xia Limin said that if I disappeared or broke up with her, she would post the video of us together directly on our unit's website.

At that time, there was a person in the Rizhao branch who was framed for destroying his family, and then the video was posted on our company's website. Even though the story was false, that person was forced to resign in the end, and the leader said it would damage the company's image.

I just got better, and several contracts have already been signed. I don't want her to make trouble at this time, so I asked her to come over and want to talk. I also prepared 2 yuan. This is what I can do. The biggest compensation I can do, after all, I have no money.

All the houses I live in are rented, and a car is all I have. I don't want to waste my feelings on her when I'm over [-], but Xia Limin doesn't listen to it at all, and wants to find a video to threaten me.

I was in a hurry, grabbed her mobile phone, and threw it into the lake. Then we quarreled. During the process of pushing and shoving, we fell off the bridge together. I got up and yelled twice, but I didn't see Xia Limin, so I climbed ashore.

I wanted to call the police, but I couldn't. I couldn't swim, and I struggled in the water for a long time. I didn't know how deep it was. Besides, my phone got wet.

I wanted to find someone, or borrow a mobile phone, but there was no one in Yuehu Park. I got in the car and put on some dry clothes, and walked home. My ears seemed to be blocked, and I went home. After washing my face, I became dizzy and lost consciousness.

I found out later that I had a fever at the time. I don’t know if it was because the water was not clean. I woke up the next night. I saw in the news that night that Xia Limin drowned in Yuehu Park, and I dare not say it. But I didn't kill anyone. "

Liu Yongxin stood behind Zhou Ning and clicked his tongue.

This kind of rhetoric was tailor-made by lawyers, completely avoiding the point of responsibility, and at best it could be regarded as moral condemnation.

To Liu Yongxin's surprise, the dialog box did not flicker this time. I don't know what the software is doing. Does this mean that what Chang Yuzhang said is true?Didn't the micro-expression on his face be interpreted as a sign of lying?

Zhou Ning and Liu Yongxin were stunned by this discovery. They looked at each other, and Liu Yongxin frowned.

"During a dispute between the two, they accidentally fell into the water. One of the survivors couldn't swim. He wanted to call the police, but his phone got in the water. There was no one around. When he got home, he fell into a coma with high fever. When he woke up, he found that the person who fell into the water had drowned. It was still on the news. Yep, that's the perfect excuse.

Not to mention murder, even the crime of inaction cannot be convicted. Now it is known that the mysterious phone is Chang Yuzhang who is in use. He is also Xia Limin's lover. The two of them fell into the water together, which may prove that Chang Yuzhang grabbed Xia Limin's hair , drown her? "

Zhou Ning nodded and continued:

"And the most important point is that the back of the deceased was injured by the handle of the battery car. There are bruises and bone cracks. Even without bone grinding, it can be judged that this is an injury during his lifetime, but who threw the battery car? Yes, because of this battery car, Xia Limin was unable to struggle and drowned."

The few people were silent. Regardless of autopsy or on-site investigation, the biggest problem now is the lack of important information about the murderer.

For example, if there is a skin flap in the nail of the deceased, DNA can be identified, and during the comparison process, there are scratch marks on the other person's body, and even the marks are exactly the same as the skin flap. This is an ironclad proof.

And this case was originally disguised as an accident. Zhang Niannian and Xu Guanhai investigated it for almost a year. If there was such obvious evidence, this case would not become a backlog.

Zhou Ning looked back at Da Zhao and Yang Xuetong. Today, these two people did not speak when they came in. They stood obediently and watched from the side. This is not like the two of them.

"Big Zhao, is something wrong with you today?"

Da Zhao shrank his neck and wrapped his police uniform coat a little tighter. The observation room here is indeed a bit cold, he sighed and said resignedly.

"It's no good to call me, Zhou Xiaozhou, what do you want me to do, tell me, anyway, our people are here, so tell me what you want to do."

Zhou Ning was very moved and patted Da Zhao on the shoulder.

"Although the battery car has been soaked in water for two days, since someone has grabbed it, it will definitely leave traces, but I don't know where the battery car was caught by the murderer. Why don't we disassemble the battery car into parts and check for fingerprints and DNA?"

Big Zhao opened his mouth wide, stared at Zhou Ning for a long time, closed his eyes as if he adjusted his heartbeat for a long time, and then opened his eyes to look at Zhou Ning.

"It doesn't matter if I do my best, Zhou Xiaozhou, but let me wipe the entire battery car with a swab, and then send it to Sister Cui for inspection. Do you think Sister Cui will be impatient?"

Zhou Ning shrank his neck, as if his ears were the roar of Sister Cui.

"Say hello in advance, and ask if you want to send the battery car or samples?"

Da Zhao didn't talk nonsense, and hurried to make a phone call to inquire. At this time, the interrogation in the interrogation room next door had ended. Xu Dayuan looked at the computer, as if he was very dissatisfied with the performance of this software.

He straightened up and waved to Liu Yufei.

"You avoid it first, and ask Director Zhou to send someone over to collect fingerprints and blood samples for Chang Yuzhang, and then examine him."

Liu Yufei rolled her eyes, she understood, what to check, but is it interesting to keep her away like this every time?

The movement of his feet didn't stop, Liu Yufei walked out, Da Zhao and Sun Gaotie walked in quickly, checked Chang Yuzhang, and collected blood samples and fingerprints, Da Zhao's physical examination did not find any scars No scratches, Chang Yuzhang was sent out directly.

Watching people go away, Xu Dayuan walked to Zhou Ning and Liu Yongxin's side.

"Don't you ask me, why did you let him go?"

Liu Yongxin didn't bother to say anything, but just stared at the direction Chang Yuzhang left. The man didn't turn back when he walked to the door, as if he couldn't leave without turning around.

Zhou Ning shook his head. Xu Dayuan has been doing criminal investigation for so many years, and his brain is not so good. Although according to Chang Yuzhang's words, he has been cleared of suspicion, but this is a one-sided statement after all. People are locked here for 24 hours at most. , does not solve any problems.

If it is released, it is possible to do something.

Zhang Niannian came over in a hurry, unable to hide the anxiety on his face, but seeing the three of them so calm, he could detect a hint of taste in the blink of an eye, and his eyes lit up after thinking about it.

"Xu Bureau, what do you mean, let us stare at Chang Yuzhang to see what he does?"

Finally someone took over, Xu Dayuan also heaved a sigh of relief, looked at the calm master and apprentice, sighed and said:
"It is necessary to monitor his mobile phone to see who he contacts and even meets. After all, without professional guidance, he cannot completely avoid being suspected."

Zhou Ning frowned, and a thought floated in his mind, but he didn't catch it. He glanced at the momentum of the corridor again, and Chang Yuzhang left very decisively, to be precise, he fled.

Looking at it now, Chang Yuzhang is the most suspicious. As an ordinary employee of an insurance company, he and Xia Limin were his first love, and they have been together intermittently for so many years. Even after Xia Limin got married, the relationship between the two has never been broken. Why did he kill him? she?
Xu Dayuan glanced at the time, then looked at Zhang Sannian.

"It's getting late. Zhang Wei's investigation needs to be done quickly. Didn't he open an Internet cafe and go there to ask the staff to find out how he is after Xia Limin's death?
There was also his ex-wife and two children, divorced in a hurry at that time, and quickly married Xia Limin, is there a reason for his ex-wife?And the divorce that year, was it before or after his accident?

Even the assets under his name, I want to know all about Zhang Wei's information!By the way, there is also Chang Yuzhang's account information. After Xia Limin's marriage, up to now, the bank has retrieved all of it. "

Zhang Sannian opened his mouth slightly, unable to keep up with Xu Dayuan's brain circuit for a while.

"Wait, Bureau Xu, are you suspicious of Chang Yuzhang or Zhang Wei?
