Chapter 61 Shocking DNA Test Results

2011 year 1 month 29 day 18: 32
Zhou Ning was not in a hurry to leave. Xu Dayuan told the city bureau about the situation, and the DNA comparison was given priority there. As for the interrogation situation, Da Zhao kept broadcasting it back and forth, and that Shen Guanlin admitted everything.

He killed Zhang Jiahui in the early morning of the 21st, drove his son's car, transported the body to the reservoir, and then dumped the body and discarded the murder weapon. His son didn't even know that he had driven the Prado.

As for Shen Weijie, he shouted at the beginning, then started crying, saying over and over again that he didn't know Zhang Jiahui, and he didn't know what this person did, and there was no intersection.

Such a confession, Zhou Ning did not believe it.

After eating the lunch box, while Zhou Ning was staring at the screen, two coughs came from the computer.

An email came to the mailbox, Zhou Ning clicked to download it, and printed it out without reading the content.

Getting up and walking to the printer, Xu Dayuan had already walked in with his mobile phone in hand, and nodded when he saw Zhou Ning and the printer at work.

"Thank you, the results are being printed, I'll treat you to dinner when you come to Qidong, it's decided!"

After hanging up the phone, Xu Dayuan came over.

"How is it, there is a result?"

Zhou Ning read the pages one by one, and when he saw the last page, Zhou Ning paused, pushed his glasses and looked at Xu Dayuan, feeling a little dazed.

"Don't make such an expression, what's the matter with you talking, I'm confused!"

"The results of the comparison are all right. The male DNA sample found in the wound belongs to Shen Guanlin. The DNA left on the outer packaging of the murder weapon and the tape on the outer packaging of the license plate belongs to the same person as Shen Weijie. As for the blood stains on the murder weapon, it is the same as Zhang Jiahui.

As for the fingerprint on the Prado tire screw, it is the same person as the unnamed fingerprint on the wrench, but I don't know who it is, but I suspect it is a woman, because there is a mark on the fingertip, which is the mark left by the long fingernail.

I was just surprised that there was an extra DNA comparison result, probably due to the fact that the two names we provided had the same surname, so we did an extra comparison. This Shen Guanlin and Shen Weijie are not father and son, so it can be said that they have nothing to do with each other. "

Xu Dayuan kept nodding his head and listened carefully to Zhou Ning's retelling until the last sentence, when he raised his head in surprise.

"I'll go, does Shen Guanlin know about such a big green hat?"

Zhou Ning shook his head. He couldn't judge this, but the interrogation information sent back by Da Zhao felt a strong desire to protect.

"Okay, don't guess here, just go downstairs to the interrogation room, the two father and son share one room, let's go to the observation room next to it, have you been there?"

Zhou Ning became interested. The system hasn't popped up the task submission interface until now. The countdown is still beating, maybe there is something missing.

"I haven't seen it, can I watch it?"

Xu Dayuan waved his hand.

"Go down and bring you a lot of insight!"

The two went downstairs and opened a door next to the interrogation room. There were two people sitting here, wearing earphones and next to a constantly rotating recording device. Zhou Ning had seen them, but couldn't name them. The two got up and Xu Dayuan waved his hands.

Zhou Ning leaned forward, a huge single-sided glass, he could clearly see the situation inside the interrogation room, Shen Guanlin was handcuffed on the interrogation chair, his hands were wearing long chain handcuffs, he tilted his head to look at the interrogating He Chunyang, and the other a recorder.

Shen Guanlin's expression was indifferent, and his eyes were a little dull.

Xu Dayuan handed Zhou Ning a pair of earphones so that he could hear the voices in the interrogation room. He Chunyang kept repeating, asking Shen Guanlin to describe the process of committing the crime, but he remained silent.

Xu Dayuan grabbed the microphone, pushed a switch, the red light came on, and then said in a low voice:
"Chunyang told Shen Guanlin that the results of the inspection just came out. His DNA was compared and it completely matched the DNA left in the wound of the deceased. There was a conflict between him and the deceased. This is an indisputable fact, but there is still an accident. Harvest, their father and son are not related by blood at all, and the comparison report is in my hand, so I asked him if he wanted to see it?"

Zhou Ning glanced at Xu Dayuan. At this time, Xu Dayuan was staring at the one-sided glass and waved his hand behind him. Zhou Ning hurriedly found the DNA comparison result of father and son and handed it to a criminal policeman.

The man hurried out, knocked on the door and entered the interrogation room.

He Chunyang smiled when he heard the knock on the door, and the recorder got up and handed the report to He Chunyang.

"The test results came out. The DNA sample left from the wound of the deceased perfectly matches yours. Of course, there is also good news. I think this must be beyond your expectations. Come and see for yourself as a professional."

He Chunyang got up, stubbed out the cigarette butt, then walked up to Shen Guanlin, handed over the report, and Shen Guanlin took it with his right hand.

Zhou Ning narrowed his eyes, Shen Guanlin was right-handed.

Shen Guanlin, who was originally calm, paused, as if he didn't understand what the police did. Seeing that He Chunyang hadn't made any other moves, he lowered his eyes slightly. When he saw the comparison content and the corresponding band screenshots, he directly flipped to the last page. Page, looking at the result, trembled all over.

"Impossible, this is fake!"

Shen Guanlin roared, and threw away the report in his hand, a few sheets of paper fell down, He Chunyang squatted down with a smile, picked up the report, and blew the dust on it.

"Don't get excited, you are not young, and your blood pressure tends to go up when you get excited, do you need me to ask a forensic doctor to get you some antihypertensive medicine?
In fact, I quite understand you, 57, the age of retirement, suddenly knowing such a thing, no one can accept it, this is the grievance of nearly 30 years, wearing this green hat, hey, I feel aggrieved! "

"Shut up, shut up! You can't find any evidence, so you're cheating on me here, I won't be fooled."

He Chunyang walked to the interrogation chair, grabbed Shen Guanlin by the shoulder, and forced him to raise his head and look at the surveillance cameras at the four corners of the roof.

"Look carefully, our interrogation is all monitored and recorded. As for the DNA comparison report, it is only because the inspection center thinks that your DNA matches, at least your son's DNA will be similar, and the comparison is made when it is found to be different. You are charged an extra fee, why are you so excited?
Besides, we are the police, what's the point of slandering you or interrogating you like this?It’s really self-indulgent, huh, my son got married and his father-in-law married a car worth nearly one million yuan. "

After finishing speaking, He Chunyang stood up directly. Zhou Ning would give a thumbs up to this set of rhetoric. It was too awesome. No matter how tight the psychological defense line was, such a bombardment would mess up most people.

According to what Da Zhao said, Shen Guanlin used to take all the blame and took all the blame on himself, but now that he knows all this, he has been cheated for almost 30 years, what else can he do?

At this moment, Zhou Ning suddenly thought, Shen Guanlin went out for 21 minutes at 06:30 on the 38st, and when he came back, he was holding a lunch box in his hand. As for arriving home at 23:32 after the operation, he also found a picture of him entering the community.

So, there are two questions here:
1. Is the box lunch a takeaway type?Or a lunch box from home?

2. After 23:32, vehicles entering and exiting the community were not searched and monitored.

Zhou Ning poked Xu Dayuan, he didn't know if he could speak in it, so he quickly typed the two points he just thought of on his mobile phone and handed them to Xu Dayuan to read.

Xu Dayuan nodded repeatedly and dialed a number.

"Go check two monitors for me, and tell me the result immediately."

Xu Dayuan rubbed his chin and turned off the red light of the microphone.

"Do you think that Shen Weijie also has an improper relationship with Zhang Jiahui, Shen Guanlin found out, and that's why he became murderous?"

Zhou Ning shook his head.

"Maybe it's the other way around. Shen Weijie was seduced by Zhang Jiahui, and you come and go, but he found out that his father and Zhang Jiahui have long been unclear. When confronted, Zhang Jiahui was enraged and scratched Shen Guanlin. Zhang Jiahui.

Zhang Jiahui was injured on the occipital, causing such a serious fracture and intracranial hemorrhage, the two of them couldn't explain clearly, so they hid her in the car, and when Shen Guanlin got off work at night, they went to the reservoir to throw the body. "

"Two people throwing the body together?"

Zhou Ning nodded.

"The dead are not heavy, but with the weight of the tires, if you want to throw people into the reservoir and keep as far away from the shore as possible, this is not something that one person can do."

Having said that, Zhou Ning paused.

"Xu Da, I haven't given Shen Weijie's shoes yet."

Xu Dayuan was taken aback.

"shoe?"
