Chapter 195 The experiment is in progress

Xu Dayuan nodded.

"From Xing Xiaoli, I think everyone in the figure skating team seems to be suspicious, especially Wang Ying, who spoke up with Miss Ranran and Li.

But I’m not polite at all. Now everyone is detained on the third floor of the gym. I want to meet you and go back and talk to them separately.”

Zhou Ning put down the whiteboard pen and nodded slightly:

"We'll study the bones later."

After receiving Zhou Ning's affirmative answer, Xu Dayuan swayed his phone.

"Sure, then I won't bother you here anymore. There are still a lot of things over there. If you have any news, I'll tell me the first time."

After seeing Xu Dayuan off, Zhou Ning came directly to the laboratory. After all, the bones of the deceased were placed here. Xia Momo heard the sound of the door opening and saw Zhou Ning and Liu Yongxin coming in.

"Xu Da is gone?"

"Well, the cervical vertebrae and cervical vertebrae sections have been scanned?"

Xia Momo nodded and opened the big screen.

A huge picture appears. The whole picture is a cross section of the cervical spine. The horizontal traces on it are very obvious, and some bone chip defects can even be seen.

“This is too clear.”

Liu Yongxin sighed in surprise, after all, he didn't understand these new homes.

"This is a newly installed high-definition camera, which can take pictures under the microscope. Many details can be observed more carefully. Zhou Ning asked me to contact Dr. Lu and borrowed it."

Liu Yongxin looked at Zhou Ning staring at the picture. It was obvious that his good apprentice had already made plans in his mind, but what could he find on the cross section?

"Do you want to judge whether the murderer is a left-handed or a right-handed?"

Zhou Ning nodded.

"Well, I always have a suspicion, and I always feel that the murderer is familiar with it, but I told me that I can't say it, so I want to see the details of the section, whether it is the proficiency of cutting or the application of left and right hands, to see if I can find some hidden information.

The first thing you can see is the hand saw when you bring it back on the scene. However, it is not like a chainsaw. You can buy it at any hardware store or supermarket. I asked Da Zhao to buy pig legs, pig neck and hand saw. We will do an experiment later and then compare it."

Liu Yongxin came over and stared at the screen as carefully as Zhou Ning. The texture on the cutting surface had a strong sense of direction. The position of the defect was probably the break of the saw blade, but the continuous cutting was almost the same frequency.

"It looks like a right-handed, very skilled, and has a balanced strength."

Zhou Ning nodded, Liu Yongxin's analysis was the same as he thought.

"Good physical strength, strong hand control ability, good at using tools, often watch movies like CSI, have anti-reconnaissance ability, and know some ways to destroy blood-stained DNA."

Liu Yongxin raised his eyebrows.

"According to this analysis, have Wang Ying and Zhuang Chunlan ruled out the suspicion?"

At the same time, the door was opened and Da Zhao heard the sound before he saw the person.

"Hurry up and help me, I can't carry it anymore. Hurry up, who will help lift the pig's head?" The three of them turned around together. The door had been opened. Da Zhao kicked the door and shouted with his neck.

But a few people were thinking about the word pig head in their minds.

"Pig head?"

"I said Zhou Xiaozhou, don't be stunned. Come and help first. I can't let go of my hands, so my sleeves are scraped on the code scanner!"

Several people quickly walked over and found that there was a big pig's head behind Da Zhao. Xia Momo was shocked. After all, the pig's head was trembling and his ears were still shaking. Zhou Ning glanced at him and found that it was not a pig's head, but the first half of a pig.

“How much did it cost?”

Da Zhao rolled his eyes.

"Zhou Xiaozhou is a matter of money, please help me! Don't worry, I will ask Director Pang to reimburse him, and we won't be allowed to bear the cost."

Hearing this, Zhou Ning quickly helped Da Zhao free his sleeves.

Several people carried half a pig and came to the operating table on the other side.

Yang Xuetong also came in with a bunch of tools in her arms, and was shocked to see the pig.

"Isn't it just an experiment? Is it a bit too much to get a pig?"

Da Zhao grinned and wiped his hands clean before he said, "

"Practice is the only criterion for testing the truth. If I study it for a long time, I can't see anything. If I get a half-surgent pig, the strength of the bones is different, so I'd just get one for the first half."

Xia Momo glanced at him.

"What about the second half? Is they selling you like this?"

"Of course, sell it. If you can, hurry up and try it. Zhou Xiaozhou, please choose, who will cut it?"

Zhou Ning looked at the few people and his eyes fell on Yang Xuetong. After all, Xia Momo had to do software operations and related records. Zhu Xingxing looked at the pig and hid back. Liu Yongxin was not physically strong, and Zhao was too energetic.

"Yang Henji comes, and after Teacher Xia's command, we imitate the murderer's cutting movement to see if we can achieve such neat sections and balanced force."

Xia Momo calculated and drew a vertical line on the pig's feet.

"Cut according to the position I've marked, but I need to collect some data, you can wait."

As he said that, Xia Momo placed a pressure pad under the pig's feet, connected it to the machine, and then clicked on the collector, which made him look better than an OK gesture.

Yang Xuetong didn't say nonsense, put on gloves, raised his hand saw, and began to saw down along the position where Xia Momo's marking.

After all, there are many dry mark inspections these days, and the hands are very stable and powerful. When you hit the ground, you can poke the saw blade directly on the pig's skin. After a few strokes, you can feel the increase in resistance on the hands. However, the speed is controlled, and the front end of the pig's feet will fall soon.

Zhou Ning held the timer and saw off a pig's forefoot, and 4:43 minutes.

I picked up the fallen pig's feet and checked the section. Not to mention that the surface is basically the same as the cross section of the deceased's tibia and fibula, they are both strip-like cross-sections with a sense of direction, which are quite neat.

"continue!"

This time, several people placed the pig on the ground, Xia Momo put pressure pads on, and Yang Xuetong knelt on one knee, controlled the direction of the hand saw with his legs, and began to creak the saw.

The cutting speed of the pig's neck was very fast. When it reached the position of the cervical spine, it stumbled slightly. Sure enough, the saw blade was broken. It took another one to continue operating. It took a total of ten minutes. Of course, the time to change the saw blade was also included.

Yang Xuetong stood up and shook her slightly sore wrists.

"Did the team leader use sawing another front pig's feet to compare?"

Zhou Ning shook his head and Zhu Xingxing raised his hand.

"Why should I try it, the team leader? I'm a left-handed person, so it's better to compare time and strength?"

"good."

Zhou Ning simply nodded, Zhu Xingxing came over and began to imitate Yang Xuetong's appearance, and tried hard toward the front pig's feet. I don't know if I kept watching, so I also summarized Yang Xuetong's actions. It took only 5:03 points for her to cut off the front pig's feet, which was comparable to Yang Xuetong's speed.

Zhou Ning paused the stopwatch and raised his head slightly.

"According to this speed, the murderer spent about half an hour to separate the corpses in the Enbo community. He killed the dead, dismantled the corpses and packed them, and cleaned them. Then the time he stayed in the Enbo community was at least one hour, and it was possible for both men and women."

The few people nodded, but Xia Momo spoke at this time.

What she calculated on the computer had results.

"Comparison of the data collected just now, Yang Xuetong and Zhu Xingxing have a huge difference in strength, but the completion level is different. You can find that the patterns on the cross-section are different by looking at the details and comparing the pictures."

As he said that, Xia Momo placed three pictures on a large screen, with the first one marked as the cross-section of the deceased's cervical spine, the second one was the cross-section cut by Yang Xuetong, and the third one was completed by Zhu Xingxing.

The first two surfaces are relatively uniform, the horizontal lines are clear, and the spacing between the lines is almost consistent, but the cross-section cut by Zhu Xingxing is much rougher, with large and small spacing, and even the depths of some places are inconsistent.

"The power is not enough, so this situation occurs. I think the murderer's strength is greater than that of Zhu Xingxing and is similar to that of Yang Xue."

Zhou Ning pulled off his gloves, washed his hands, and then said slowly:

"It seems that the murderer is an adult male, right-handed. In this way, Zhuang Chunlan and Wang Ying are less suspicious. Let's wait for the test results. Of course, there is also a surveillance investigation. When will Xiaoqu come?"

October 7, 2011 7:33

Zhou Ning had just entered the office, and a shout came from behind. When he turned around, he saw Da Zhao coming with a stack of inspection reports.

"Is the identity of the deceased confirmed?"
Chapter completed!
