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

"Absolutely, this position in the shoes, hard, should be poured into the milk and then dried, go back and send it for inspection, this will definitely come out quickly." Zhou Ning let out a long breath, this discovery was consistent with his inference just now.

took out his mobile phone and dialed Liu Yufei's mobile phone.

"Sister Fei, is it convenient to speak?"

"Well, you say, I entered the room and closed the door, is there something new?"

"Find some new evidence, but we need a laboratory to conduct a quick test to prove our analysis, we won't go to the eighth floor, go back to the technical department first, you can delay for a while, such as go to the monitoring room, find the monitoring screen of the second unit, ask Ye Chengchen some questions that don't hurt or itch, can you give us half an hour?"

"Understood, don't worry, I'll delay here, you go back quickly, and talk to Xu Ju again."

"Okay." After speaking, Zhou Ning hung up the phone, and at this time, Da Zhao ran back with some excitement, holding the camera, and showed Zhou Ning.

"Zhou Xiaozhou, I found a new discovery, on the glass of the window, I found a mark, I looked at it for a long time before I found out that this mark should be inadvertently pasted on the cheeks after makeup, with lines on it, you see!" Zhou Ning glanced at it, and sure enough, there was a whitish mark on the glass, and the top seemed to have something shiny, and there were two horizontal lines below the shiny, Zhou Ning squinted.

"Sampling, huh?" Da Zhao held up a piece of sampling paper, which was the kind of sticky substance.

"I carefully sampled twice, and I saw that the imprints were a lot shallow, so I can rest assured that this amount is definitely enough to detect." Zhou Ning nodded, such a foundation, especially on the lines at the corners of the eyes, it is easy to leave human dandruff, if this can be compared successfully, at least it can prove that when the child was thrown downstairs, she was next to her, as for whether she is a participant, it depends on the inspection of Sister Cui's clothes.

"Let's go, Lao Yang will go to the eighth floor and collect samples of Ye Chengchen's cosmetics, let's go back directly, and send them for testing as soon as possible." Everyone knew the seriousness of the matter, and without delay, Lao Yang carried the box down.

After waiting downstairs for two minutes, Lao Yang also ran over quickly, gasping and getting into the car, the driver Lao Wang kicked the accelerator, and with the whistle of the siren, the car sped out quickly.

...... At 16:44 on March 3, 2013, a rush of footsteps came, everyone in the observation room looked at the door, Da Zhao was panting, holding a stack of reports, with an excited look on his face, and stuffed the report to Zhou Ning.

"The results came out, not just the slippers and daddy shoes, but also the nail residue and the clothes on the two children." This made Zhou Ning's eyes light up, and he quickly read it carefully, the report was very detailed, and he quickly picked the key points and read it.

"1. On the vacuum cleaner and mop sent for inspection at noon in 801, the hairs found belonged to two people after DNA testing and comparison, one was Ye Chengchen and the other was Zhang Bo, and Ye Chengchen's fingerprints with milk stains were found on the doorknob on the fifteenth floor, and the milk stains were consistent with the dairy products in Zhang Yangrui's stomach; 2. On the edges of the slippers and dad shoes submitted for testing, residues of the same type of dairy products were found in the collected samples, and the DNA of the boy Zhang Yangrui was detected at the same time; 3. On the slippers submitted for inspection, the nail decorations found 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. On the boy's Zhang Yangrui's pants, the palmprint morphology, DNA samples, and nail polish residues collected are completely consistent with Ye Chengchen's palmprints, DNA, and nail polish residues, and according to the palmprint morphology, it can be analyzed that Ye Chengchen's palms are grasping Zhang Yangrui's pants with his palms facing up; 5. On the back of the girl's coat, Zhang Bo's palm prints and fingerprints, as well as DNA residues, were found, and their forms also formed grasping marks, and in the residue of Zhang Ruixue's nails, a piece of skin dander was found, which was detected by DNA comparison and belonged to Zhang Bo. Of course, there are many, 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 pale, and he bowed slightly.

"Okay, I know, help me inform Zhang Ping, let him prepare, send Zhang Bo over in a while, I'll go over with Yu Fei to meet this Ye Chengchen first." After saying this, Xu Dayuan sighed and walked quickly towards the next door.

After a moment, pushing the door and entering the interrogation room directly, Ye Chengchen was startled by the sudden voice, and looked up at Xu Dayuan who came in, his eyes shifted from Xu Dayuan's face to his hand.

Seeing so much paper, her eyelashes fluttered, and she quickly staggered her head. Liu Yufei's eyes lit up and she hurriedly walked 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 yet? Maybe you think that what you do is designed seamlessly, but the current technology is not something you can understand, and not reading much is really vicious, why do you kill two children? Are those two children holding you back from getting married? Ye Chengchen didn't speak, but at this time, he completely lost his previous confidence.

"Don't say okay, then let me tell you, you and Zhang Bo made a plan in advance, tricked Zhang Ruixue to Zhang's house for the night, and you even changed Zhang Bo's mobile phone in advance, a second-hand mobile phone, and downloaded some apps decently. 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 if it is that photo, you are transmitted by Bluetooth, although we can't find the path, but it doesn't matter that we know it's an HTC phone. On the night of the second day, you returned to the second unit of Building 5 of Vanke Charm City, and you were still dressed up carefully, after all, this kind of dress is very different from your usual dress, who would have thought that such a dress and height would be a woman, of course, you cleaned room 801 thoroughly, and disposed 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 will stay in the stairwell on the fifteenth floor, you should put on shoe covers at this time, let alone wear such a pair of shoes with characteristics, after all, from the shoe print, we can easily find you. Seeing Zhang's mother go out, you went directly to 1502, of course, it may be that Zhang Bo came out to call you, after all, they were his two children, it is estimated that you can't get started, when you walked towards 1502, you put on shoe covers, so there were no footprints. After entering the house, I put on my shoes and stepped into a pair of cotton slippers that I don't usually use, and followed Zhang Bo to find the two children, I think it was Zhang Ruixue who Zhang Bo hugged, after all, Zhang Ruixue is big, and it is impossible for you to hug it casually, and you go to the guardrail in the living room and pick up Zhang Yangrui. The kid reacted a lot, and when he struggled, 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 with his backhand, controlling his movements, he walked to the window of the master bedroom with Zhang Bo, Zhang Bo carried Zhang Ruixue's clothes on the back, knocked the screen window on the side, and threw the child down, and you followed closely behind and threw Zhang Yangrui downstairs. But your strength is not as good as Zhang Bo, when you left downstairs, Zhang Yangrui kept struggling, you finally carried Zhang Yangrui's crotch and threw the child out of the window upside down, and then you left 1502 quickly, and put the cotton slippers in the shoe cabinet. When you go out, take off the shoe covers, at this time the milk stains on the shoe covers are splashed on your dad shoes, and you also have some stains on your hands, so you leave fingerprints and milk stains and DNA on the staircase door, back to 801 You dressed up and left while the chaos was there, how about I am right, do you have anything else to add? Ye Chengchen was not silent this time, and looked at Xu Dayuan with a pale face.

"I didn't, not me, I didn't kill anyone!" Xu Dayuan held up Zhang Yangrui's live photo, Liu Yufei showed it to Ye Chengchen before, but she avoided her gaze, and at this time, just in front of Ye Chengchen's gaze, Xu Dayuan held up such a tragic photo.

"Didn't kill anyone? Look at this child, he is only one and a half years old, and he is still learning to speak in Yiya, so he was forced to separate from his mother, the two of you, one of you fights for custody but does not raise him, just to embarrass his ex-wife, and the other knows that he has children and daughters, and he does not stay away and provokes him to kill his children. Take a closer look, he fell from the fifteenth floor and fell directly on the marble steps, the steps were all smashed, the child was broken from head to toe, more than a dozen fractures, internal organs were ruptured and displaced, and the abdominal cavity was full of blood, do you know what the brain is like? Take a closer look, look at the liquid flow of this child's brain, don't you have a weak heart, you can sleep last night, you haven't read again, and you have received nine years of compulsory education, what you do can be regarded as a person's behavior? Ye Chengchen was shocked by Xu Dayuan's thunderous reprimand, she forgot to turn her head, just leaned back on the chair like that, slid down slowly, and the bloody photo was almost pasted on her face, and there was nowhere to escape.

Ye Chengchen's chest rose and fell strongly, he raised his hand and grabbed his hair, and with the movement, the handcuffs and chains made a crisp sound, and Ye Chengchen pulled his hair and shouted 'Ah'.

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

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

"Cry what cry, talk! What is the end, you don't want to talk and talk, we will interrogate Zhang Bo now, if Zhang Bo says it, the responsibility will be put on you, and you will have no chance to speak, you will sign if you understand, and refuse to admit the various facts and evidence of the police investigation. As he spoke, Liu Yufei grabbed a document that had just been printed out and slapped it in front of Ye Chengchen, followed by a pen that was stuffed into Ye Chengchen's hand.

Ye Chengchen kept shaking his head, looking at the pen in his hand, and the printed paper, she couldn't see the handwriting on it clearly, threw away the pen and shouted loudly.

"I don't sign, it's all Zhang Bo who forced me, he forced me!"
