Chapter 35 Two DNAs on a Nylon Rope
March 12 11:14
The investigation work has officially started, and the information of each building has been distributed. Because of the huge workload that needs to be investigated, the people from the port police station have also been transferred, and they will start to act after a meeting and assignment.

Zhou Ning and Zhao Xinli were in a group. They were not assigned a fixed building number, but they still stood in the square and waited.

After all, it was Saturday, so many policemen came to the community, and many spectators came down to watch. Of course, most of them were old men and women.

Zhao Xinli has good eyesight. Among the crowd watching the excitement, he spotted the fat old lady in the morning at a glance, and dragged Zhou Ning to hurry over.

"Auntie, do you remember me?"

The fat old lady was taken aback and smiled.

"Remember, young people, what are you doing here? Didn't you find that old man surnamed Chen?"

The fat old lady said to Zhou Ning that it is convenient to be good-looking. No matter what age she is, she is friendly to such a handsome face. Zhou Ning motioned them to go to the stone table in the square, People sat down, Zhou Ning asked.

"Auntie, you have been in the community for a long time, can you tell me about Chen Zhenya in detail?"

"Chen Zhenya? Is that the old head Chen?"

Zhou Ning nodded.

"Yes, it's him. We want to know about the situation with you. Who is this Chen Zhenya familiar with in the community, or who has a very bad relationship with him? Even if he has quarreled, it's fine. Tell us everything you can know."

The fat old lady stopped smiling, with a hint of caution on her face.

"Young man, tell your aunt, what did this man do? Why are there so many police investigations?"

Zhou Ning paused. The case has not yet been settled. If it is revealed that it is not in compliance with the rules, Zhao Xinli did not think so much. He approached the fat old lady and said in a low voice:
"Auntie, I can only tell you one thing. This Chen Zhenya was killed. We didn't find the murderer. I want to let you know that we can catch the murderer earlier. You can feel at ease living here, right?"

Zhou Ning was stunned, and glanced at Zhao Xinli, who blinked at Zhou Ning.

Sure enough, the old lady had a clear face and slapped her thigh.

"I'm guessing right. The old man is still so weird and stubborn, and he will cause trouble sooner or later."

Zhao Xinli squatted on the ground, approached the fat old lady as if chatting about homework, and asked gossipingly.

"Auntie, tell me, we don't take notes, we just chat, tell me what you saw or heard, and we will investigate what happened, don't worry, nothing will involve you , Aren’t we all for the safety of our children and family members, if we live in the same neighborhood as the murderer, you won’t be able to sleep either.”

Zhou Ning didn't speak, Zhao Xinli was a chatterer, and these few words touched the heart of the fat old lady.

"The fat boy is right, so I'll talk to you guys. I told my son and wife before that they told me not to mind my own business, but this old man Chen has a bad character, so we all go around him. "

"Why is your character bad? Didn't you say that this old man keeps looking for his wife? Is there anything else going on?"

The fat old lady leaned forward, looked around, lowered her voice, and said mysteriously:

"Dirty things, who can talk about it, this summer, a little girl from a family in Building No. [-] couldn't be found. We all helped to find her, and finally found someone in the gazebo outside the community. The child was scared. broken.

After comforting her for a long time, the child said that an old man carried her to the gazebo and touched her up and down. His panties were all stripped off. After hearing this, the parents hurriedly asked which old man it was, and the child pointed at Old Chen. Head, said it was this grandpa black.

The parents quarreled with old Mr. Chen and almost started to fight. Old Mr. Chen yelled with a stick, how could a four or five-year-old kid be believed?

After quarreling for a long time, the family was afraid of shame, so they took the child away without calling the police. After all, there was no monitoring and no evidence. Just relying on the child's dictation, this thing doesn't count, but we all told the child not to approach alone That old man. "

Hearing this, Zhou Ning was stunned, the old man was so dirty.

Suddenly, he thought that Yu Jingwei, who was renting a house, was traveling with his daughter.
Zhao Xinli's small eyes widened with disbelief.

"Really, this old man is so old, can he do this?"

The fat old lady looked serious, tilted her head and said:
"Although I didn't call the police, I don't think the child will lie because of this. The family is located in 601, Unit [-], Building [-]. If you don't believe me, you can ask, but the parents of that family are boring, and they don't necessarily tell them if they ask, and they are afraid of affecting the child. Bar."

Zhou Ning winked at Zhao Xinli, and handed him a few words typed on the phone. Zhao Xinli got up to make a call. This matter must be verified. If it is true, it is likely to be revenge.

"Auntie, was he discovered, just this time?"

The fat old lady nodded.

"This is the only time I know. It's not a glorious thing. Who can say it with great fanfare? That is, this time the child was lost. Everyone helped to find it, so I found out a little bit, but the community Not many inside know the details."

Zhou Ning rummaged through the pictures on his phone. During the previous project meeting, he saved Yu Jingwei's photo and handed it to the fat old lady.

"Auntie, look, do you know this person?"

The fat old lady took a closer look, and then came to a realization.

"Isn't this the tenant who the police went to that house yesterday?"

"Has he had a relationship with this Chen Zhenya? Or have they had any conflicts? As far as I know, there is a girl in his family."

The fat old lady shook her head.

"I'm not familiar with this one. This person doesn't rent a house very much. He always comes to live with a tall young man. Oh, he also has a daughter. It seems that he is studying in the Haigang Primary School next to the community."

"A tall young man?"

The fat old lady looked up and down at Zhou Ning.

"Well, I'm a little shorter than you by two or three fingers, and I'm about 1.8 meters tall, but I'm a bit stronger than you. I've only met him but never spoken to him, and I don't know his last name."

Zhou Ning recalled it, and it seemed that he was talking about Wang Yi, who was very tall. I remembered that Wang Yi said that he and Yu Jingwei were classmates, and Yu Jingwei also gave the dog to him to take care of when he went on a trip.

Right here, a man ran quickly to the side of the fat old lady, and pulled the old lady up from the chair with anxiety and vigilance on his face.

"Mom, why did you come out? The child is crying at home. Go back and have a look."

The fat old lady was pulled to stand up and patted her son's arm vigorously.

"What are you pulling me for? The police asked me not to make it clear. What are you in a hurry for?"

"You didn't shut the door, go home quickly."

The man spoke in a hurry, and stretched out his hand to pull the fat old lady. In fact, Zhou Ning understood the man's reaction very well. After all, in this society, one thing more is worse than one thing less. Especially when encountering a murder case, many people are unwilling to testify. No one is afraid of revenge. After all, these They are all vicious people, and ordinary people can't deal with them.

Zhou Ning stood up and nodded slightly towards the fat old lady.

"Thank you, auntie, rest assured that we will not affect your normal life."

The man didn't say anything else, and left with the fat old lady.

At this time, Zhao Xinli and Xu Dayuan walked back, seeing the fat old lady leaving, they all looked at Zhou Ning.

Zhou Ning repeated what the fat old lady said, and Xu Dayuan nodded repeatedly.

"It's understandable. They all have children, and no one wants to cause trouble. I asked He Chunyang to bring Yu Jingwei back. He has been found in Luxi Province. Zhao Xinli should send Xiao Zhou's forensic doctor back."

Zhou Ning didn't resist, and he didn't have much to participate in. As for the follow-up, he still had to wait for the results of their interrogation.

It was almost five o'clock when we returned to the forensic room.

Seeing Liu Yongxin in front of the computer, Zhou Ning hurried over.

"Master's city bureau test results came out?"

Liu Yongxin took off his reading glasses and moved away from the seat in front of the computer.

"It's here. Let's take a look. Sea salt, fish, and sediment components were found in the crevices of the deceased's nails. As a result of blood analysis, high concentrations of nifedipine and losartan potassium were found in the deceased's blood and stomach contents." , it seems that the deceased had high blood pressure and had taken medicine an hour or two before death."

Zhou Ning took a closer look. This result was expected. After turning a few pages, he saw the sampling results on the nylon rope and found two DNAs. One belonged to the deceased, and the other was not found in the system.

This discovery is almost as likely as winning the lottery. The probability of the murderer's DNA being collected on a nylon rope is small enough.

Seeing this, Zhou Ning was thoughtful.

When the deceased slashed Chen Zhenya's face, he was wearing latex gloves. He couldn't have strangled Chen Zhenya and then remembered that he didn't wear gloves. He put them on in the middle. It cost 32 knives. Your gloves are broken?

"Master, if the suspect is found and the blood is drawn and compared to the DNA, is this conclusive evidence?"
