Chapter 458 He Forced Me

Zhu Xingxing nodded vigorously, reached out and touched the inside of the shoe, his eyes became more determined.

"Absolutely. The part inside the shoe is hard. It should be filled with milk and then dried in the shade. Go back and send it for inspection. The result will definitely come out soon."

Zhou Ning let out a long breath. This discovery is considered to be consistent with his deduction just now.

He took out his cell phone and dialed Liu Yufei's cell phone.

"Sister Fei, is it convenient to talk?"

"Well, you said, I entered the room and closed the door, did you find anything new?"

"We have found some new evidence, but we need a quick laboratory test to prove our analysis. We will not go to the eighth floor. We will go back to the technical department first. You can delay it. For example, go to the monitoring room and find someone from the second unit." Monitor the screen, ask Ye Chengchen some painless questions, can you give us half an hour?"

"Understood, don't worry, I will delay here, you go back as soon as possible, and tell Bureau Xu again."

"it is good."

After finishing speaking, Zhou Ning hung up the phone. At this time, Da Zhao ran back excitedly, holding up the camera, and showing it to Zhou Ning.

"Zhou Xiaozhou, I found a new discovery. On the glass of the window, I found a mark. After looking at it for a long time, I realized that this mark should be left over from the cheeks after makeup, with lines on it. look!"

Zhou Ning glanced at it, and sure enough there was a whitish imprint on the glass, and there seemed to be something shiny on the top, and there were two horizontal lines under the shiny, Zhou Ning squinted his eyes.

"Did you sample it?"

Da Zhao held up a piece of sampling paper, which was a kind of sticky substance.

"After carefully sampling it twice, I can see that the imprint has faded a lot. Don't worry, this amount is definitely enough for detection."

Zhou Ning nodded. This kind of foundation, especially on the lines on the corners of the eyes, is easy to leave human dander. If this comparison is successful, it can at least prove that when the child was thrown downstairs, she was by the side. If you are a participant, it depends on the inspection of sister Cui's clothes.

"Let's go, Lao Yang goes to the eighth floor and collects samples of Ye Chengchen's cosmetics. Let's go back directly and send them for inspection as soon as possible."

Everyone knew the seriousness of the matter, and without any delay, Lao Yang went down with the box.

After waiting downstairs for 2 minutes, Lao Yang also ran over quickly and got into the car panting. The driver Lao Wang stepped on the gas pedal, and the car sped out with the whistle of the siren.

January 2013, 3 3:16
There was a sound of hurried footsteps, and everyone in the observation room looked towards the door. Da Zhao was out of breath, holding up a stack of reports, with an excited look on his face, and handed the reports to Zhou Ning.

"The results came out, not just the slippers and daddy shoes, but nail residue, and the clothes on the two children."

This made Zhou Ning's eyes brighten, and he quickly read it carefully. The report was very detailed, so he quickly read it carefully.

"1. The hair found on the vacuum cleaner and mop sent for inspection at noon on 801, after DNA testing and comparison, belonged to two people, one was Ye Chengchen and the other was Zhang Bo. Ye Chengchen was found on the doorknob on the fifteenth floor with a milk The fingerprints of the stains, the milk stains are consistent with the milk products in Zhang Yangrui's stomach;
2. The same type of dairy product residues were found in the samples collected from the edges of the slippers and daddy shoes submitted for inspection, and the DNA of the boy Zhang Yangrui was detected at the same time;

3. The nail ornaments found on the slippers submitted for inspection were of the same material grade as those on the nail fragments submitted for inspection, and Ye Chengchen's DNA was also detected on them;

4. The shape of the palmprint, DNA sample, and nail polish residue collected on the boy Zhang Yangrui's pants are completely consistent with Ye Chengchen's palmprint, DNA, and nail polish residue, and can be analyzed according to the shape of the palmprint. Zhang Yangrui's pants with the grip facing up;
5. On the back of the girl Zhang Ruixue's coat, Zhang Bo's palm prints, fingerprints, and DNA residues were found, which also formed traces of grasping. In the residue of Zhang Ruixue's nails, a piece of dander was found. After DNA comparison and detection, it belonged to Zhang Bo. "

Of course, there are many more, very detailed, but these are the most important. After reading the test report, Zhou Ning handed the report to Xu Dayuan, Xu Dayuan's face was livid, and he nodded slightly.

"Okay, I got it. Help me inform Zhang Ping, let him prepare, and send Zhang Bo over in a while. I'll go and meet Ye Chengchen with Yufei first."

After saying this, Xu Dayuan sighed, and quickly walked towards the next door.

After a while, he opened the door and entered the interrogation room. Ye Chengchen was startled by the sudden voice, and suddenly raised his head to look at Xu Dayuan who came in. His eyes shifted from Xu Dayuan's face to his hands.

Seeing so many papers, her eyelashes trembled, and she quickly turned her head away.

Liu Yufei's eyes lit up, and she hurried over.

"Leader, is the report out?"

Xu Dayuan nodded, handed the report to Liu Yufei, and walked in front of Ye Chengchen alone.

"Don't you want to say yes? Maybe you think that the design of what you have done is flawless, but the current technology is not something you can understand. It is really vicious to not read much. Why did you kill two children? Could it be that Two children getting in the way of your marriage?"

Ye Chengchen didn't speak, but at this moment he completely lost the confidence he had before.

"Don't say yes, let me tell you, you and Zhang Bo made a plan in advance to trick Zhang Ruixue into Zhang's house for the night, and you even changed Zhang Bo's mobile phone in advance, a second-hand phone that has been flashed, and it still looks decent Downloaded some apps.

Then delete and restore the factory settings, and even found a photo of Zhang Bo’s ex-girlfriend as a screensaver. Your plan is simply too thoughtful. Even that photo, you transmitted it using Bluetooth, although we can’t find the path. But that's okay, we know it's an HTC phone.

On the evening of the 801nd, when you returned to Unit [-], Building [-], Vanke Charm City, you were still well-dressed. After all, this dress is very different from your usual one. Who would have thought that such a dress and height is a woman. Of course, you cleaned Room [-] thoroughly. Yes, get rid of all traces of Zhang Bo, but remember to empty the vacuum cleaner bag next time.

Early in the morning, according to the appointed time, you stayed in the stairwell on the fifteenth floor. You should have put on your shoe covers at this time, and you shouldn't be wearing such a pair of characteristic shoes. After all, we can easily find you from the shoe prints.

Seeing Zhang's mother going out, you go directly to 1502. Of course, it may be Zhang Bo who came out to call you. After all, they are his two children. I guess you can't do it. When you walk towards 1502, put on your shoe covers , so no footprints were left.

After entering the house, I put on a pair of cotton slippers that I don’t use often, and followed Zhang Bo to find the two children. I think it was Zhang Ruixue who was hugged by Zhang Bo. Inside the guardrail, Zhang Yangrui was picked up.

The child reacted violently. When struggling, you kicked the bottle over and the milk flowed into the cotton slippers, but you didn't pay attention at the time.

Holding the child in his backhand, controlling his movements, he walked to the window of the master bedroom with Zhang Bo. Zhang Bo held Zhang Ruixue's clothes on the back, smashed open the screen window sideways, and threw the child down. You followed closely and threw Zhang Yangrui downstairs.

However, you are not as strong as Zhang Bo. When you were thrown downstairs, Zhang Yangrui struggled continuously. In the end, you grabbed Zhang Yangrui's crotch and threw the child out of the window upside down. Then you quickly left 1502 and put the cotton slippers in the shoe cabinet.

When you go out, take off the shoe cover. At this time, the milk stain on the shoe cover splashes on your old shoes, and some of your hands are also stained, so fingerprints, milk stains and DNA are left on the stair door , Back at 801, you dressed up and left in the chaos. I'm right, do you have anything to add? "

Ye Chengchen was not silent this time, and looked at Xu Dayuan with a pale face.

"I didn't, it wasn't me, I didn't kill anyone!"

Xu Dayuan held up Zhang Yangrui's on-site photo. Liu Yufei showed it to Ye Chengchen before, but she averted her gaze. Now, just in time to meet Ye Chengchen's gaze, Xu Dayuan held up such a tragic photo.

"Didn't kill anyone? Look at this child, he was only one and a half years old, and he was still babbling, and he was forced to separate from his mother. You two, one of you fought for custody but didn't raise it, just to embarrass your ex-wife, and the other knew that he had He has sons and daughters, and if he doesn't stay away, he even persuades him to kill his children.

Take a closer look, he fell from the [-]th floor and fell directly on the marble steps. The steps were all smashed. From head to toe, the child suffered more than a dozen fractures, internal organs were ruptured and shifted, and the abdominal cavity was full of blood. You know what brain matter is. like?
Come take a closer look and see how the child's brain contents flow out in a liquid state. Don't you feel guilty, you were able to sleep last night, you have never read a book, and you have received nine years of compulsory education. What you have done can be regarded as A person's behavior? "

Ye Chengchen was overwhelmed by Xu Dayuan's thunderous reprimand, she even forgot to turn her head, just leaned on the chair like that, and slid down slowly, the bloody photo was almost pasted on her face, there was nowhere to escape.

Ye Chengchen's chest rose and fell violently, and he raised his hand to grab his hair. Following the movement, the handcuffs and chains made a crisp sound, and Ye Chengchen pulled his hair and shouted 'ah'.

With a cold face, Liu Yufei slapped the table. Xu Dayuan was taken aback by such an abrupt sound, and Ye Chengchen stopped crying directly.

Liu Yufei looked at Ye Chengchen coldly, and glanced at her from top to bottom.

"Why are you crying? Talk! What happened? You can talk if you don't want to. We are now interrogating Zhang Bo. If Zhang Bo says it, the responsibility will be placed on you. You won't have a chance to speak. If you understand it, sign it." , refusing to acknowledge the various facts and evidence investigated by the police.”

With that said, Liu Yufei grabbed a document that had just been printed out, and patted it in front of Ye Chengchen, and then forcefully stuffed a pen into Ye Chengchen's hand.

Ye Chengchen kept shaking his head, looked at the pen in his hand, and the printed paper. She couldn't read the writing on it, so he threw away the pen and shouted loudly.

"If I don't sign, Zhang Bo forced me, he forced me!"
