Liu Yongxin shook his head.

"The evidence is not solid."

Zhou Ning nodded and placed the evidence bag containing the kitchen knife on the table.

"When strangling Chen Zhenya, the latex gloves were torn. I don't think the murderer would notice. After all, that was the time when his adrenaline was soaring. The thrill of revenge occupied all his thoughts. There might be residue on the knife. Let's see.

, can you always stay lucky?"

Liu Yongxin saw an excited smile on his face when he saw the kitchen knife.

"Okay, have you found the first scene?"

Zhou Ning nodded and learned everything from Liu Yongxin about the discovery of Bihailantian Garden.

"Never underestimate the aunts in the community. Their observation skills and information are always the best. Come on, don't let us start work."

After saying that, the two began to carefully observe the handle of the kitchen knife. According to the shape of the wound on the deceased's face, Liu Yongxin judged that the murderer was right-handed. If the damaged glove was not found, it must be in a relatively hidden position, so it could only be under the palm or the side of the little finger.

Location.

After some searching, I found a small triangular piece of latex glove at the very end of the knife handle.

It scrapes right against the base of the kitchen knife's shaft and pokes out of the upward-turned groove of the kitchen knife. This kitchen knife is quite old and the handle is also movable.

There were blood stains on the fragments, and Liu Yongxin bared his teeth and laughed.

"Hurry up and call Xiao Liu to come up. Don't send it to the county hospital. Send this thing and the murder weapon to the city bureau. I'll call the city bureau's inspection center now and ask him to do it carefully."

Zhou Ning thought for a while and found the evidence bag of the deceased's clothes.

"Since we are submitting for inspection, we still require people to do so. Why don't we also submit the clothes and pants of the deceased for inspection? I previously found a few dried marks on the front door of the deceased's pants. I'm not sure if they are urine or something else."

Liu Yongxin nodded, naturally he agreed with this.

Zhou Ning took out the phone and asked Xiao Liu to go upstairs. Liu Yongxin gave instructions and Xiao Liu hurriedly left. Then Liu Yongxin called an acquaintance in the city bureau. He was so polite that he was not so respectful when talking to Xu Dayuan, but he asked him to work overtime.

When doing work, you really need to speak well.

After getting home from get off work, Zhou Ning buried himself in the bed after taking a shower.

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 your work?"

"No, I'm off work. I'm at home."

Xia Momo was obviously relieved and her tone became more relaxed.

"I have nothing else to do, I just want to ask how that model is and if it can help you?"

Zhou Ning smiled, as if the two little pear dimples of Xia Momo were right in front of him.

"I have been so busy that I didn't even 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 say polite words, then you can have a good rest. I won't disturb you anymore, as long as I can help you."

Zhou Ning sat up.

"Okay, you should have a good rest today. You didn't sleep last night. By the way, this case is urgent, so I won't go to your class tomorrow."

"I understand, you can talk about it after you finish your work. Besides, if you are not free on the weekend, you can come to me to pick up a few plaster statues, practice them when you are free in the evening, take pictures and send them to me on QQ."

"Okay, then I'll give you a call when I go there."

"Good night."

"Good night."

After hanging up the phone, Zhou Ning plugged the phone into the charger and fell asleep. Of course, within two minutes, he reappeared in the room without doors and windows. There was still a pile of books in front of him, and the system beep sounded again.

Case number one

The next day.

As soon as Zhou Ning arrived in the team, he saw busy figures.

Zhao Xinli followed Zhou Ning into the office with a mysterious look on his face, closed the door without Zhou Ning asking, and Zhao Xinli started talking.

"Yu Jingwei and his daughter were brought back last night. Their blood has been drawn and tested to see if it matches the DNA you extracted. Isn't this comparison quick?"

Zhou Ning glanced at his watch.

"If I sent it last night, it would be almost ready to come out."

Zhao Xinli raised his eyebrows and bumped Zhou Ning's arm. In fact, he wanted to bump his shoulder, but he was not tall enough.

"Then why are you still hanging around? Hurry up and look online!"

Unable to resist this guy, Zhou Ning didn't argue and quickly turned on the computer. The sound was like a tractor starting for a while. This old and worn-out computer was successfully turned on.

Zhao Xinli was on the sidelines and kept complaining.

"You said we have already divided into districts, so why don't you give us some new household items? Just leave this old computer outside, and people who collect rags won't even bother to pick it up."

"If you have the guts, tell Xu Da about this."

Zhao Xinli was stunned for a moment, smiling and waving his hands without seeing his teeth.

"I just complained, but I heard that we are moving to a new building soon. It will be completed by the end of the year. It is estimated that we can go there to work in May next year. Finally we are no longer on this small second floor. Don't say I still miss it a little."

Zhou Ning rolled her eyes at him and opened her mailbox without saying anything. Sure enough, ten minutes ago, an email was sent from the municipal inspection center.

After opening the download, both of them stared at the screen. Zhao Xinli couldn't understand, while Zhou Ning read the reports one by one.

The position on the front door of the deceased's pants was found to be the deceased's rice liquid.

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.

But when he turned to the last report and saw the conclusion, Zhou Ning was stunned.

"What's going on, what's going on, tell me!"

"The blood sample No. 82 submitted for examination does not match the DNA of No. 2 and is not the same person. That is to say, Yu Jingwei's DNA and the DNA found on the nylon rope and knife do not belong to the same person."

"Caught by mistake?"

Zhou Ning nodded, quickly printed out the report and handed it to Zhao Xinli.

"Send it to Xu Da quickly."

Zhao Xinli ran away with the report, and just when Liu Yongxin came in humming a tune, the two almost bumped into each other. Zhao Xinli didn't even bother to talk, so he ran to Xu Dayuan's office to see Zhao Xinli. Liu Yongxin walked in with a puzzled look on his face.

.

"Why is this kid so dumbfounded so early in the morning? What happened?"

"The city bureau just sent the test results. The traces on the pants are the rice liquid of the deceased. The DNA collected on the knife we ​​sent for samples belongs to the same person as the one on the nylon rope. However, the Yu Jingwei blood sample sent for testing last night does not match this DNA.

"

Liu Yongxin was also stunned.

"This means that the direction of the investigation is wrong?"

Zhou Ning said nothing, biting his lip and thinking deeply. If the murderer followed Chen Zhenya to his house, killed him, and obtained the password of the deceased's house, this could be explained.

However, the body is hidden in the house rented by Jingwei. Not everyone can enter this house. At present, 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 Song Luqing who live there.

Wang Yi.

Thinking of Wang Yi, Zhou Ning thought of the fat old lady who had said that Wang Yi had a daughter who attended Gangkang Primary School. She had ignored this detail before. Zhou Ning raised her head and went straight to Xu Dayuan's office.

Pushing the door open and entering, Zhao Xinli was standing in front of Xu Dayuan. Seeing Zhou Ning come in, Xu Dayuan looked over.

"What happened to forensic doctor Xiao Zhou?"

"Xu Da, let me interrupt you. I have an idea. The aunt who provided clues before once said that Wang Yi has a daughter who goes to Gangkang Primary School. Can we find out about that child?"

Xu Dayuan looked solemn.

"Do you suspect that the deceased had molested this child before?"

Zhou Ning nodded and shook his head, clenching his fists at the same time.

"Perhaps it's more than that. The girl the fat aunt said was lucky. She was discovered in time, so the family did not investigate further. A father who knows such a thing will be very broken, and the possibility of revenge is extremely high."

Xu Dayuan stood up, grabbed his hat and put it on.

"You and Da Zhao go to school with me, and take Sister Feng with you."

Sister Feng is the only female police officer in the team. She is fifty years old. She usually handles internal affairs in the team. Whenever there are female suspects or children involved, she usually follows her. After all, it is more convenient.

When everyone went downstairs, Liu Yongxin gestured with Zhou Ning to make a phone call at the door of the office. Zhou Ning understood that Liu Yongxin meant to call him if there was news. Zhou Ning nodded and followed everyone.

The car started moving together, and Xu Dayuan finally remembered and patted his thigh hard.

"I'm so busy. School is on holiday today, right?"
Chapter completed!
