Chapter 36 What happened?
Liu Yongxin shook his head.
“The evidence is not strong.”
Zhou Ning nodded and placed the evidence bag of the kitchen knife on the table.
"When strangling Chen Zhenya, the latex gloves were torn. I don't think the murderer would notice it. After all, his adrenaline was surging at that time. The pleasure of revenge occupied all his thoughts. There might be some residue on the knife. Let's see if we can stay lucky!"
When Liu Yongxin saw the kitchen knife, an excited smile appeared on his face.
"Sure, have you found the first scene?"
Zhou Ning nodded and told Liu Yongxin everything he had discovered in the Blue Sea and Blue Sky Garden.
"Never underestimate the aunties in the community. Their observation skills and information are always the best. Come on, don't just stand there, let's get started."
After that, the two began to carefully observe the handle of the kitchen knife. According to the shape of the wound on the victim's face, Liu Yongxin judged that the murderer was right-handed. So the damaged glove was not discovered because it must be in a hidden place, so it could only be under the palm or on the side of the little finger.
After searching for a while, I found a small triangular piece of latex glove fragment at the very end of the knife handle.
It just scraped the base of the knife handle and protruded into the groove where the handle flipped upward. This kitchen knife is a bit old and the handle is movable.
There were bloodstains on the fragments, and Liu Yongxin grinned.
"Hurry up, hurry up, tell Xiao Liu to come up. Don't send him to the county hospital. Send this thing and the murder weapon to the city bureau. I'm going to call the city bureau's testing center now and ask them to do a thorough job."
Zhou Ning thought about it and found the evidence bag containing the deceased's clothes.
"Since we're sending it for inspection, and we're asking for it from a human, why don't we send the deceased's clothes for inspection as well? I noticed a few dried marks on the front of the deceased's pants, and I'm not sure if it was urine or something else."
Liu Yongxin nodded, he naturally agreed with this.
Zhou Ning took out his phone and asked Xiao Liu to come upstairs. After Liu Yongxin gave some instructions, Xiao Liu left quickly. Then Liu Yongxin called an acquaintance in the Municipal Bureau. He was so polite that he was even more respectful than when he spoke to Xu Dayuan. However, if you ask someone to work overtime, you do have to say it nicely.
After getting home from get off work and taking a shower, Zhou Ning buried himself in the bed.
Fatigue and sleepiness came over him, and just when he was about to fall asleep, his cell phone rang. Zhou Ning quickly grabbed the phone, saw Xia Momo's name, and quickly answered the call.
"Hey, Teacher Xia!"
"Zhou Ning, did I disturb you at work?"
"No, I'm off work and at home."
Xia Momo was obviously relieved and her tone became more relaxed.
"I don't have anything else to do. I just want to ask you about the model and whether it helps you."
Zhou Ning smiled, as if Xia Momo’s two dimples were right in front of him.
"I have been busy and didn't tell you. This model has helped us a lot. Today we have found the identity of the deceased. Thank you, Teacher Xia."
"No need to be polite. Just have a good rest. I won't disturb you. I'll just help you."
Zhou Ning sat up.
"Okay, you should have a good rest today. You didn't sleep all night last night. By the way, this case is urgent, so I won't go to your class tomorrow."
"I see. Let's talk about it after you're done. If you don't have time on the weekend, you can come to my place and get a few plaster statues. Practice when you're free in the evening. When you're done, take a photo and send it to me on QQ."
"Okay, I'll call you when I'm about to go over."
"Good night."
"Good night."
After hanging up the phone, Zhou Ning plugged his phone into the charger and fell asleep. Of course, only two minutes later, he appeared in the room without doors and windows again. There was still a pile of books in front of him, and the system prompt sounded again.
Case number one……
…
The next day.
As soon as Zhou Ning arrived at the team, he saw busy figures working there.
Zhao Xinli followed Zhou Ning into the office with a mysterious look on his face. After closing the door, he started chattering without Zhou Ning asking.
"Yu Jingwei and his daughter were brought back last night. Their blood has been drawn and sent for testing to see if it matches the . This comparison should be quick, right?"
Zhou Ning glanced at his watch.
"If you sent it last night, it would be almost ready to come out."
Zhao Xinli raised his eyebrows and bumped Zhou Ning's arm. Actually, he wanted to bump him on the shoulder, but he was not tall enough.
"Then what are you still standing there for? Go check it out online!"
Unable to convince this guy, Zhou Ning did not argue and quickly turned on the computer. There was a sound like a tractor starting up, and this old and broken computer was successfully turned on.
Zhao Xinli stood aside and continued to complain.
"You said we have set up a district, why don't you give us some new things? Just throw this broken computer outside, and the junk won't even bother to pick it up."
"If you have the guts, go tell Xu Da about this."
Zhao Xinli immediately backed down, smiled with his teeth showing but his eyes not showing and waved his hands.
"I'm just complaining, but I heard that we're moving to a new building soon. It will be completed by the end of the year, and we'll probably be able to work there in May next year. We'll finally not be on this small second floor anymore. I miss it a little bit."
Zhou Ning rolled his eyes at him and opened his mailbox without saying anything. Sure enough, ten minutes ago, the Municipal Bureau Inspection Center sent an email.
After opening the download, both of them stared at the screen. Zhao Xinli couldn't understand it, while Zhou Ning read the reports one by one.
The front area of the deceased's trousers was found to contain the deceased's semen.
The two DNAs found on the nylon rope and the knife belonged to the same person. This discovery did not surprise him much, after all, it was expected.
However, when Zhou Ning turned to the last report and saw the conclusion, he was stunned.
"What's the matter? Tell me!"
"The blood sample No. 82 sent for testing did not match the DNA sample No. 2 and was not from the same person. In other words, Yu Jingwei's DNA did not belong to the same person as the DNA found on the nylon rope and the knife."
"Wrong one?"
Zhou Ning nodded, quickly printed out the report and handed it to Zhao Xinli.
"Hurry and send it to Xu Da."
Zhao Xinli ran away with the report, and happened to meet Liu Yongxin who came in humming a tune. The two almost bumped into each other. Zhao Xinli didn't even bother to say anything, and ran to Xu Dayuan's office. Looking at Zhao Xinli, Liu Yongxin walked in with a puzzled look on his face.
"Why is this kid so dazed so early in the morning? What happened?"
"The city bureau just sent us the test results. The stain on the pants is the deceased's semen. The DNA collected from the knife we sent for sample belongs to the same person as the one on the nylon rope. However, the blood sample of Yu Jingwei sent for test last night does not match this DNA."
Liu Yongxin was also stunned.
"Does this mean that the investigation is going in the wrong direction?"
Zhou Ning didn't say anything, biting his lip and thinking. If the murderer followed Chen Zhenya to his home, killed him, and got the password to the deceased's home, this would be a reasonable explanation.
However, the body was hidden in the house rented by Yu Jingwei, which is not accessible to everyone. Currently, only four people can enter: the landlord has the key, Yu Jingwei has the key and password, and the other two are Song Luqing and Wang Yi who are staying there temporarily.
Thinking of Wang Yi, Zhou Ning remembered what the fat old lady said, that Wang Yi had a daughter attending Gangkou Primary School. He had overlooked this detail before. Zhou Ning raised his head and went straight to Xu Dayuan's office.
Pushing the door open, Zhao Xinli was standing in front of Xu Dayuan. When Xu Dayuan saw Zhou Ning coming in, he looked over.
"What happened to Xiao Zhou, the forensic doctor?"
"Master Xu, I'm going to interrupt you for a moment. I have an idea. The aunt who provided the clues before once said that Wang Yi has a daughter who attends Gangkou Primary School. Can we find out more about the situation from that child?"
Xu Dayuan looked solemn.
"Are you suspecting that the deceased had molested this child before?"
Zhou Ning nodded and shook his head, clenching his fists.
"Maybe it's more than that. The girl that the fat aunt mentioned was lucky. She was found in time, so her family didn't investigate further. A father would be very upset if he knew about such a thing, and the possibility of revenge is very high."
Xu Dayuan stood up, grabbed his hat and put it on.
"You and Da Zhao come with me to school. Oh, and bring Sister Feng with you."
Sister Feng is the only female police officer in the team. She is fifty years old and is usually responsible for handling clerical affairs in the team. Whenever there is a female suspect or when children are involved, she usually follows them, after all, this is more convenient.
Everyone went downstairs. Liu Yongxin made a phone gesture to Zhou Ning at the door of the office. Zhou Ning understood that Liu Yongxin meant to call him when there was any news . Zhou Ning nodded and followed everyone.
When the car started moving, Xu Dayuan finally remembered and slapped his thigh hard.
"I'm so busy. Is school closed today, Sunday?"
