Chapter 401 Computer Experts
Xiaoqu has already started to operate, took a look and quickly handed it to Zhou Ning and the others, blinking with doubts on his face, Zhou Ning glanced at him.

"What's wrong?"

Xiao Qu quickly handed the report to Zhou Ning.

"Look for yourself. I just flipped through it. I can't understand anything else, but I don't understand what it means to not find valid and complete DNA on this murder weapon."

Zhou Ning took it and read it again. There were many reports, and the most important points were clear at a glance.

Zhang Hongwei's DNA and his fingerprints were extracted from the comb that Fu Chunyu's family was carrying, and Yang Liang's incomplete fingerprints and DNA were found on the iron wire in the cellar, which is straightforward enough.

Fu Chunyu's DNA was detected in the samples taken from Yang Liang's tricycle. This big Zhao said that the rear bucket was dirty, and there were bloodstains in the black gaps, and there was no trace of washing at all.

In the report, the grease extracted from the Mencun Bridge was compared, and it was consistent with the sample collected from the rear wheel of Yang Liang's tricycle. This can show that the vehicle used to transport the body parts to the moat was this tricycle.

The corpse in the cellar was confirmed to be Feng Shujuan, and the DNA collected from the skeleton in the septic tank matched Fu Chunyu's. As for Xiaoqu's doubtful part, Zhou Ning read it carefully.

As for the blood found in the greenhouse, it was consistent with Fu Chunyu's DNA.

This is the murder weapon found in the septic tank, an ax and two kitchen knives, both of which have gaps on the blades of the kitchen knife and ax. If the arm is strong enough, the process of dismembering the corpse can indeed be completed.

Fu Chunyu's DNA was found on the three murder weapons, but the pollution was too severe and no other information could be found. Zhou Ning frowned after reading it.

He is confused now, the evidence and the analysis are reversed, there is Fu Chunyu's blood on Yang Liang's car, and the tricycle was used to throw the body, so this is different from yesterday's analysis, could it be that his analysis is wrong?
In addition, the most worrying problem still occurred. After soaking in the septic tank for so long, if there were no gaps in the blades of the kitchen knives and axes, the DNA of the deceased would not be obtained.

Thinking of this, Zhou Ning dialed Cui Lili's phone, the phone rang, and the other side connected.

"I knew that once the email was sent, you would call as soon as possible. Don't listen to me. These are some of the earliest samples taken last night. After all, the pollution is serious, and I don't think it is reliable.

In the early hours of the morning, I had already disassembled the murder weapon. I washed all the joints of the three murder weapons and vibrated the stuffing. The results of this batch of samples will come out in two or three hours. Send it over. "

Zhou Ning smiled.

"Thank you, big sister. I'm already busy flying here. If I send it to the province for inspection, it will take too long, and you won't be able to know what I want here. Not to mention communication, it will make people collapse, but it's because of your hard work!"

"It's useless to talk less, I'm still staring at the machine, hang up now!"

Zhou Ning rubbed his nose and hung up the phone. Cao Pingzhang poked Liu Yongxin enviously.

"I said, your apprentice is not an ordinary leader. This working atmosphere is too enviable. You must know that the laboratory is generally not easy to fiddle with. Let me do an inspection and do what I say. I will never do more. , you, the laboratory, actually figured out a way to solve it yourself, amazing!"

Liu Yongxin rolled his eyes at him.

"Don't be so sour, my apprentice treats everyone sincerely, and will definitely help everyone fight for welfare within his ability. The equipment that the inspection department changed a while ago is of the top international standard. These are all applied by my apprentice and the leader. Expanded funding, after all, seeing the effect of technology on the detection work, this is complementary, you know!"

Cao Pingzhang raised his hands in a gesture of surrender.

"I was wrong, I brought shame upon myself, this is, here we want money but no money, no people, and being able to persist in the autopsy is already my greatest limit, forget it and don't ask, it's useless to ask anyway, anyway Wait for a few hours, then go to work, I have someone send the body."

Said that Cao Pingzhang went out, and the body was brought in not long after. Sure enough, it was frozen overnight, and the smell was much reduced, especially compared with yesterday's septic tank screening, this is already much happier.

Dressed neatly, Zhou Ning began to carefully check the watch of the corpse. He had already seen a rough look yesterday, and what is needed today is a detailed autopsy.

The posture of the deceased has been placed in a supine position, the arms have not changed their direction, and they are still held high. The corruption of the hands, feet, abdomen and face is the most serious, and some of them have become ossified, but the upper arms and legs are still intact, and some are even dehydrated. , a bit like air-dried duck.

Being able to achieve such a state shows that the body of the deceased did not contain much water and fat, and he was thin. Moreover, at the end of August, there was little rain, so he could reach the state of partial bones and partial mummies.

After the inspection, no other scars were found. Zhou Ning then cleaned out the highly corrupted tissue in the abdomen, and then checked the dead man's fingers. This time, he found that there was a broken phalanx in the sand with cut marks on it.

On the ribs, a stab wound was also found, in the middle of the second and third ribs. In such a position, although it failed to stab the heart, it could instantly immobilize the deceased.

Zhou Ning was not surprised by this result. The deceased was likely to be stabbed. She wanted to resist, and her fingers were almost cut off. Then the deceased was strangled by the murderer and thrown in the cellar. However, it may be because of panic or lack of strength. The iron wire It was not tightened, and when it was buried, it slowed down again, broke free from the wire, but could not climb out.

After finishing the autopsy, Zhou Ning breathed a sigh of relief, tore off the equipment, and the body was sent away. After washing his hands, Zhou Ning took out his mobile phone and called Da Zhao.

"How's it going?"

"It's still being cleaned up. It looks like the cellar isn't that big, but there's a lot of sand in the lower layer. What's the matter, is the autopsy over?"

"Well, look carefully. I think there will be a knife in the cellar. Looking at the shape of the wound, it is a double-edged dagger with a width of about 2.8 cm. I think it should be under the corpse."

Da Zhao was speechless for a while, wondering what Zhou Ning saw in the autopsy and how he gave such accurate information.

"Okay, I'll look for it now."

After hanging up the phone, Zhou Ning looked at Xiao Qu.

"You are here to smell, is the work progress faster."

Xiao Qu looked at the relaxed Zhou Ning, he rarely joked like this, it seemed that things were going well, Xiao Qu also smiled.

"Don't say it, I'm here with you, it seems to be progressing very quickly, I really found something here."

It was originally a joke, but Xiao Qu actually discovered something, which surprised Zhou Ning. He opened the window and walked to Xiao Qu's side, staring at the row of laptops in front of him.

"Tell me what you find."

Liu Yongxin also came over, Xiaoqu quickly found the video that was just captured, and opened it for the two of them to watch.

"Look at this black car, the license plate is full of mud, and I can't see what it is, so when the software searches, I let it go. I found that at 10:20 am on October 10, this car The car came to the textile district, but it stopped at the store in front.

You see, a person got out of the car, wearing a sweater and a hat mask, carrying a bag through the small passage on the side, and went directly into the residential building behind. I found the map and checked the location. This used to be Building No. [-] .

At 11:02, he returned the same way, but at this time the mask was gone. He turned his head to the east side here, and I compared his face. Then I quickly searched again based on the information of this vehicle at 16:00 p.m. after the video.

Sure enough, within 2 minutes of being blocked by that vehicle, I tracked the car at an intersection on the east side. I tracked it all the way according to the intersection he passed, and finally went around the urban-rural junction in the west of the city and disappeared.

And after October 10th, I haven’t seen this car at various intersections in Dayao City. Of course, it may have been cleaned. After all, I don’t know the car number. I searched Zhang Hongwei’s name, and there is only one white car left under his name. Wuling Hongguang. "

As he said that, Xiaoqu clicked to open an electronic map. On it was the intersection where the vehicle found and passed, marked by a red line, and the last location where the vehicle disappeared.

To Zhou Ning's surprise, this location turned out to be the intersection leading to the north side of Guanzhuang Primary School.

Could it be that he drove Fu Chunyu to Yang Liang's house, so where did he do it?
and many more
There was a hiss in Zhou Ning's mouth. Liu Yongxin raised his head and glanced at Zhou Ning. Seeing that Xiao Qu seemed to be about to speak, Liu Yongxin raised his hand to cover Xiao Qu's mouth, lest Xiao Qu's words would interrupt Zhou Ning's thoughts.

After thinking for a while, Zhou Ning stared at the computer and said seriously:

"Look up Zhang Hongwei's address, and of course the original address of his hometown. Didn't he study in Guanzhuang Elementary School before? It seems to be called Longwang Guanzhuang Village? By the way, don't they have a technical department in the city bureau?"

Xiaoqu laughed.

"Yes, it's not a serial car accident. We all went there to support. I heard that you brought a computer expert, and he left quite at ease. I will also be an expert this time."

Liu Yongxin rolled his eyes and slapped Xiaoqu on the head.

"Are you stupid, just this computer expert makes you laugh like this? But to be honest, these people's technology is indeed not as good as yours, hurry up and work, comrade expert."

Xiaoqu nodded, and started to operate with crackling hands. Several computers kept switching back and forth. After a while, many monitoring screens appeared. If you look carefully, they all seem to be from the road, and they look similar.

Zhou Ning blinked, obviously this is the traffic police system. In Qindao City Bureau, Xu Dayuan gave Xiaoqu permission, but it was only the third day in Dayao City. Could it be that Huang Youdao also gave him permission.

"Did you get in through technical means, or did you give you permission?"

Xiao Qu quickly waved his hands.

"Director Zhou, don't say that. Team Huang specially gave me the authorization. Otherwise, I wouldn't dare. If this is traced, it will be criminal responsibility. We can't joke like that."

Liu Yongxin stared, Xiao Qu quickly moved away.

"Uncle Liu, don't worry, I found it. Look at this black car, it looks very similar overall."
