Xiaoqu was squeezed to the point where there was no room, so she pushed the person above her head and shouted.

"Don't block my screen, I'm still comparing!"

Everyone stepped aside for a moment, and Zhou Ning glanced at the two screenshots. To be honest, they were just dark silhouettes, and he couldn't see the facial features clearly at all. He didn't know what Xiao Qu was comparing.

But from this angle, you can clearly see the three people in front, two behind and one behind, and the person sitting behind is very thin, with a small head, lying on the gap between the driver's seat and the co-pilot's seat, with his chin resting on his hands, and he can see the side face form.

Such a discovery gave Zhou Ning a pause and quickly looked at the remaining two silhouettes.

Don't say just looking at it like this, you will find the problem. The person in the driver's seat looks like Zhang Wannian at first glance, because his jaw is very characteristic, the bite is misaligned, his face is crooked, and he can't tell it if he doesn't speak. side twisted.

In this picture, the person turned his head slightly, facing the direction of the screenshot. Although it was dark, but the white teeth were dislocated up and down, one could tell it was him.

Zhou Ning quickly patted Xiaoqu on the shoulder, pointed to the display screen and said:
"Can you zoom in on this screenshot? It's the figure on the co-pilot."

"It's blurry when zoomed in."

Zhou Ning thought about it.

"I don't pursue image quality, as long as the contrast is stronger, I can see their bone shape clearly, only the light and shade are enough. I thought too much before. It's not that you can't find people in this screenshot, but you can't follow the previous method. Use the skull search.

You can refer to the X-ray pictures and increase the contrast. After all, Zhang Wannian and Liu Xiangrui can be distinguished from this picture. Zhang Wannian has a dislocated bite, while Liu Xiangrui is extremely thin, and his skull, ulna, and radius are smaller than ordinary people. "

When Zhou Ning said this, Liu Yongxin also took a closer look, and kept nodding beside him.

"Don't tell me, you can really tell the difference this way. Although the car film is too dark, after your treatment, you can still see the outline, and the teeth can be seen clearly. The one driving the car is indeed Zhang Wannian, and the one with the small head behind is Liu Xiangrui, but Why does the co-pilot have such a big head?"

Such a sentence made several people glance at it, and Xiao Qu blinked.

"Maybe it's a matter of angle. Arranged in the order of front and back, the person closest to the monitoring position is the co-pilot, followed by Liu Xiangrui sitting in the middle in the back row, and the farthest is Zhang Wannian in the driver's seat. His head must be the largest. Yes, but it's a pity that this person only has a profile, and there is nothing deformed."

As he said that, Xiao Qu kept moving his hands and continued to operate, looking dazzled, but after a while, the picture was processed again, and the face of the co-pilot could no longer be seen as a picture, but after the comparison was clear, Zhou Ning stared at the screen and pushed his glasses.

"Are there glasses on the bridge of this man's nose?"

Several people looked at the screen, and Liu Yongxin shook his head.

"I can't tell, this is just a black line, I can't tell what it is."

Zhou Ning shook his head and pointed to the position behind this person's ear.

"Here, after the adjustment of Xiaoqu, you can see that the outer ear of this person is standing up. If you look at it from the front, it is what we often call a downwind ear, and the temporal bone behind the ear is sunken, and a shadow can be seen at the position from 1 to 7 o'clock.

Here I think it is the temples of the glasses, and the depression of the temporal bone just shows that this person has worn glasses since he was a child, and the skull is not small, and the head is relatively wide. It is likely that there are indentations of the temples on both sides under the temple, so his head is big. It is not a matter of proportion, but itself is a big head. "

Speaking of this, Zhou Ning paused, and looked at Da Zhao and Yang Xuetong. Although Lao Yang is not as fat as Da Zhao, he is not small. He is 178 tall and weighs about the same. He has a strong figure, a typical Ludong's characteristic Chinese character face, the size of the head is about the same as that of Da Zhao.

An idea jumped out, Zhou Ning quickly went on to say:

"Da Zhao took Lao Yang, Sun Gaotie, and Xiao Zou, and now they are going downstairs. Zou Jialong is in the middle of the rear seat on Poussin. Shake it down, and then we'll come up and compare."

Da Zhao suddenly realized, he understood what Zhou Ning was going to do, he was trying it out for himself, so he quickly waved his hands and took a few people down.

Zhou Ning walked to the window, and Xia Momo stood on one side. She looked at Zhou Ning and asked:

"Have you ever wondered who the person in the co-pilot seat looks like?"

Zhou Ning nodded.

"I have an idea, but I'm not sure yet."

Xia Momo didn't speak any more, after a while, these people came back, rushed to Xiaoqu, connected the camera to the computer, and imported the pictures.

Everyone gathered, Zhou Ning pushed Zhao, and said to Zhu Xingxing:

"Measure Da Zhao, Zou Jialong and Yang Xue's head circumference and front-to-back diameter. I think Lao Yang's head circumference is a little bigger than Da Zhao's, and Zou Jialong's is the smallest."

"impossible!"

Lao Yang immediately retorted.

Big Zhao patted him with a hippie smile.

"Don't get angry. Although you are thinner than me, you have a big bone frame. I have a small frame and my head is not big."

Zhu Xingxing rolled his eyes, and moved over with a measuring tape.

"Whatever the boss said, I will hurry up and do it. There is so much nonsense, I will know when I sit down and measure it."

"I said you can't get a tape measure, this thing strangles your head, can you murder?"

Da Zhao was slapped and didn't talk nonsense anymore. Zhu Xingxing measured the three of them one by one, looked at the ruler and said to Zhou Ning:
“杨哥的头围稍微大一点62前后径18.3，赵新利的头围60前后径18.2，邹家龙的最小54，前后径15.4。”

Zhou Ning looked at the screen, directed Xiao Qu to measure the length of the heads of the three people on the car, and then asked Zhu Xing Xing to measure the front and rear diameters again. On the picture, the difference between Da Zhao and Lao Yang is negligible, while the difference between Zou Jialong is very large , a direct difference of 1.3 cm.

After such an operation, Xiao Qu seemed to think of something, found a few more pictures, and took some measurements.

"Based on this method, the head circumference and height of the co-pilot is somewhat similar to that of Brother Yang, but he is a little shorter. There is not a big difference between fat and thin. The most important thing is to wear glasses."

Everyone looked at Yang Xuetong, which made Yang Xuetong feel embarrassed.

"It's not based on my figure, is it?"

Zhou Ning took out his mobile phone and dialed Xu Dayuan's mobile phone.

"Leader, we have an analysis here. I don't know if it will be helpful for your investigation. Why don't you come over and take a look. In addition, I need to contact Miss Fei and Xiaobai. I need all the heights of these people related to Zhang Wannian and Liu Xiangrui Weight, and of course photos, so we can compare."

"You wait, I'll be there right away."

Half an hour later, Xu Dayuan came to Zhou Ning's office. After some explanations, he already understood the comparison method, so he looked at Zhou Ning.

"Just tell me, do you have someone you suspect?"

Zhou Ning nodded.

"Currently, in terms of height and head circumference, the most suspicious person is Zhang Wannian's brother-in-law Zhang Song. Director Xu showed me the photos of the administrative detention at that time. Zhang Song's height, weight and head circumference are very consistent.

It's just that I can't figure it out. According to the information from Dayao City, Zhang Song has nothing to do with his ex-brother-in-law Zhang Wannian, and they even made trouble at the police station.
In addition, I always feel that the co-pilot looks like he is wearing glasses. I don’t know if Zhang Song is short-sighted. After all, there are no glasses in the administrative detention photos. If he doesn’t have glasses, I suspect another person. "

Da Zhao spoke quickly, staring at Zhou Ning and asked:

"Who?"

Liu Yongxin was thoughtful, he seemed to think of something, Zhou Ning didn't prevaricate this time, but said directly:

"Wang Kaitao, this person's height, body shape and head circumference also match. Haven't you noticed that Zhang Wannian, Wang Kaitao, and Zhang Song are all very similar in body shape?"

Da Zhao blinked, with an unbelievable expression on his face, he spread his hands and said in doubt:

"I believe Zhang Song. That kid eats, drinks, prostitutes and gambles. He has no money and wants to cheat Zhang Wannian. He can do anything. After all, he is a gambler! But this Wang Kaitao graduated from nursing, because he earns little. It’s not nice to say that I just resigned to work alone, but it’s easy to earn thirty or forty thousand, as for it?”

Liu Yongxin pushed Da Zhao, Da Zhao quickly shut up, Sun Gaotie was eager to try.

"What the boss said must be right. Whether it's Zhang Song or Wang Kaitao, it's enough to compare the DNA between these two people. It's better to say that one test is worse than one test. Let's stop arguing."

In a word, everyone quieted down and looked at Zhou Ning and Xu Dayuan. Xu Dayuan was silent for a moment and took out his mobile phone. At this time, it is better to have a direction than to wait. After all, there is no trace of Zhang Song, so just find one.

"I'll get someone to bring Wang Kaitao again. We were in a hurry last time, and we didn't keep his blood sample or fingerprints. You can go to the system to compare them first. As for Zhang Song, after Yufei and the others arrived in Huining, they didn't know what to do. Knowing the procedure, it seems that after seeing Sun Nan, I went to the place where Zhang Song appeared to check the monitoring."

As he said that, the phone in his hand had been dialed at this time, and there were many people from the Municipal Bureau, and Xu Dayuan dialed Zhang Ping's number. "Hey Zhang Ping, you can contact Wang Kaitao now. I remember that he has two jobs to run every afternoon. You should record it there. Go directly and bring him to the city bureau to draw blood."

"Okay, we're near the Central Hospital, and we're just one foot away from that place. The leader wait a moment, and I'll call you when I catch someone."

What does such a yelling mean? Zhang Ping was clear and hung up the phone without talking nonsense. Xu Dayuan contacted Liu Yufei again. This time the conversation was a bit long, and they had just landed there.

Liu Yongxin approached Zhou Ning and raised his hand to poke his arm.

"If Wang Kaitao is the murderer, then we looked for him once before, so we should have alerted the snake."

Zhou Ning exhaled, of course he was worried about this.

"It's 2013 now. If you want to take a train or an airplane, you need a real-name system. Even if you want to escape from here quickly, there is no trace. In fact, if he runs away, it is a good thing, because as long as he runs away, he must be the murderer." .”

Liu Yongxin nodded, approving his apprentice's analysis. At this moment, Xu Dayuan's cell phone rang, and it was Zhang Ping who called.

"Hey, how's it going, did Wang Kaitao find it?"

"Leader, Wang Kaitao ran away!"

I'm in a bad mood. I closed a chapter yesterday and released it in the afternoon. It's so repetitive. I've replaced the content of the previous chapter. If you can't see it, delete the book and add it back. It'll be fine.
