Liu Yongxin shook his head.

"The evidence is not conclusive."

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

"When strangled Chen Zhenya, the latex gloves were broken, I don't think the murderer would notice, after all, that time was the period of his adrenaline rush, the thrill of revenge occupied all thoughts, and there may be residues on the knife, so let's see if we can keep lucky!"

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

"Okay, you've found the first scene?"

Zhou Ning nodded, and learned from Liu Yongxin about what he found in the Blue Sea and Blue Sky Garden.

"Never underestimate the aunts in the community, their observation skills and information are always the best, come on, don't be stunned that we start work."

After speaking, the two began to carefully observe the handle of the kitchen knife, according to the shape of the deceased's facial wound, Liu Yongxin judged that the murderer was right-handed, so the glove was not broken, it must be a relatively secret location, so it can only be under the palm, or the side position of the little finger.

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

It is scraped right at the root of the kitchen knife shaft, sticking out of the groove where the handle is flipped upward, this kitchen knife is some years old, and the handle is also moving.

There was blood on the fragment, and Liu Yongxin gritted his teeth.

"Hurry up, call Xiao Liu to come up, don't send it to the county hospital, this thing and the murder weapon, send it to the city bureau together, I will call the inspection center of the city bureau now, and let him do it carefully."

Zhou Ning thought about it and found the physical evidence bag of the deceased's clothes and pants.

"Since it is sent for testing, it is still the kind that requires people, or send the deceased's clothes and pants for examination, I found that there are several dry marks on the door in front of the deceased's pants, not sure if it is urine, or something else."

Liu Yongxin nodded, and he naturally agreed.

Zhou Ning took out the phone and asked Xiao Liu to go upstairs, Liu Yongxin commanded for a while, Xiao Liu hurriedly left, and then Liu Yongxin called an acquaintance in the city bureau, that politeness, he didn't talk to Xu Dayuan so respectfully, but let the family work overtime, it is really necessary to say it well.

When he got home from work and took a shower, Zhou Ning buried himself in bed.

Exhaustion and drowsiness came up, just when he was about to fall asleep, the mobile phone rang, Zhou Ning quickly grabbed the phone, saw Xia Momo's name, and quickly answered the phone.

"Hey, Teacher Xia!"

"Zhou Ning, am I disturbing your work?"

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

Xia Momo obviously breathed a sigh of relief, and her tone was more relaxed.

"I don't have anything else to do, I just want to ask how that model is, and if it helps you?"

Zhou Ning smiled, as if Xia Momo's two small pear vortices were in front of him.

"I've been busy, I haven't told you a word, this model has helped us a lot, and I have found the identity of the deceased today, thank you, Mr. Xia."

"No need to say kind words, then you can rest well, I won't bother you, just help if you can."

Zhou Ning sat up.

"Okay, you can rest well today, I didn't sleep all night last night, by the way, this case is more urgent, I won't go to your class tomorrow."

"I know, you'll talk about it when you're busy, and if you don't have time on the weekend, you can come to me to take a few plaster statues, practice when you have time in the evening, draw a picture and send it to me on QQ to see."

"Okay, then I'll call you when I go over."

"Good night."

"Good night."

Hung up the phone, Zhou Ning plugged the phone into the charger, and fell asleep like this, of course, only two minutes, he reappeared in the room without doors and windows, there was still a stack of books in front of him, and the system's prompt sounded again.

Case 1.......

......

Following.

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

Zhao Xinli followed Zhou Ning into the office with a mysterious face, closed the door and didn't need Zhou Ning to ask, Zhao Xinli chattered.

"Yu Jingwei and his daughter were brought back last night, and their blood has been drawn and sent for testing, just to see if it can match the DNA you extracted, this comparison is fast, right?"

Zhou Ning glanced at his watch.

"If I sent it last night, I could almost come out."

Zhao Xinli raised his eyebrows and bumped Zhou Ning's arm, in fact, he wanted to hit his shoulder, but his height was almost high.

"What are you doing in a daze, hurry up and take a look on the Internet!"

couldn't resist this goods, Zhou Ning didn't argue, and quickly turned on the computer, and the sound like a tractor starting sounded for a while, and the old and dilapidated computer was successfully started.

Zhao Xinli was on the side, still complaining.

"You said that we have set up districts, why don't you give us some new things, just throw this broken computer outside, and it is not uncommon for people to pick up the rags."

"You have a kind of, say this to Xu Da."

Zhao Xinli was stunned for a second, smiling and waving his hand when he saw his teeth.

"I'll complain, but I heard that we're about to move to a new building, which will be completed at the end of the year, and it is estimated that I will be able to go to work in May next year, and finally not on this small second floor, not to mention that I still miss it a little."

Zhou Ning glanced at him, opened the mailbox directly without saying much, and sure enough, ten minutes ago, an email was sent from the inspection center of the Municipal Bureau.

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

The location of the front door of the deceased's pants was tested to be the deceased's rice green liquid.

The discovery that the two pieces of DNA found on the nylon rope and the knife belonged to the same person was not much of a surprise to him, after all, it was expected.

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

"What's the matter, what do you say!"

"The blood sample No. 82 sent for testing did not match the DNA No. 2 and was not the same person, which means that the DNA of Yu Jingwei and the DNA found on the nylon rope and knife did not belong to the same person."

"Caught the mistake?"

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

"Hurry up and send it to Xu Da."

Zhao Xinli ran away with the report, and when he ran into Liu Yongxin humming a tune, the two almost collided, Zhao Xinli didn't bother to speak, so he ran to Xu Dayuan's office to see Zhao Xinli's figure, Liu Yongxin walked in with a puzzled face.

"Why is this kid stunned early in the morning, what's going on?"

"The test results were sent by the city bureau just now, and the traces on the pants are the deceased's rice green liquid, and the DNA collected on the knife we sent the sample belongs to the same person as the nylon rope, but the blood sample of Yu Jingwei sent for testing last night does not match this DNA."

Liu Yongxin was also stunned.

"That means the investigation is going in the wrong direction?"

Zhou Ning didn't speak, biting his lip and pondering, if the murderer followed Chen Zhenya to his house, killed him, and got the password of the deceased's house, this could be explained.

However, the hidden body is in the house rented by Jingwei, this is not for everyone to enter, at present, there are only four people who 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 borrowed there.

Thinking of Wang Yi, Zhou Ning thought of what the fat lady said that Wang Yi had a daughter who went to school in Port Primary School, and ignored this detail before, Zhou Ning raised his head and went straight to Xu Dayuan's office.

Pushing the door in, Zhao Xinli was standing in front of Xu Dayuan, and saw Zhou Ning coming in and Xu Dayuan came over.

"What's wrong with Forensic Doctor Xiao Zhou?"

"Xu Da, let me interrupt you, I have an idea, the aunt who provided the clue once said that Wang Yi has a daughter who goes to the port primary school, can we find out about the situation with that child?"

Xu Dayuan's face was solemn.

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

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

"Maybe it's not just that, the girl that the fat aunt said was lucky, she was found in time, so the family didn't dig deeper, a father would be very devastated if he knew about such a thing, and the possibility of revenge was extremely great."

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

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

Sister Feng is the only female policeman in the team, she is fifty years old, and she is usually responsible for handling internal affairs in the team.

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

The car moved together, Xu Dayuan remembered, and slapped his thigh hard.

"I'm busy, school is off on Sunday today, right?"
