: Throw away and buried nearby

Zhou Ning laughed twice, and such a sudden action made the two of them confused.

"The hardness of human skulls is between 3-4, and the hardness of natural marble is between 3.5-5.5. I can't find a very suitable stone, so let's use this to simulate it.

Use three actions to test the marble shattered marks, and then compare the marble shattered marks, so that you can understand how the murderer injured the dead.”

Xu Dayuan nodded.

"There is no problem with the experiment, but why did you give me the marble?"

"I'm too tall and it's not easy to hit when I lift it."

Da Zhao didn't bother to be a big deal, so he came over and handed the wrench to Zhou Ning.

"It's okay, I'm short, you'll smash it."

Zhou Ning glanced at him.

"I'm bored, hurry up and do the experiment."

Da Zhao didn't talk nonsense anymore, wearing goggles, and raised the wrench horizontally with both hands.

"Boss, you're ready, I'll come!"

"Aim at me and hit my hand and be careful with your head."

Da Zhao shivered and looked bitter.

"Boss, don't scare me, I'm here."

As he said that, Da Zhao swung his wrench and smashed it towards the marble slab. The marble slab was smashed and splashed out some fragments, but it was not broken. Xu Dayuan also turned over the slab and looked at it. He could feel Da Zhao in his hand.

The strength was not broken and unexpected.

"It's not broken?"

Zhou Ning nodded, marked a 1 on the marble slab with a marker, and then signaled to change to the second piece. This time, Xu Dayuan grabbed the flat hands horizontally, and Da Zhao held the wrench in one hand and smashed it downwards.

With a bang, the marble slab exploded diagonally, and a lot of gravel splashed like a force point, and the cracks also appeared diagonally along the force point. Xu Dayuan took a look.

"This marble has cracks. Next time you smash it, avoid the brown-red pattern, smash it here, and come again."

Zhou Ning quickly went to mark and then moved out of position. Da Zhao held the wrench in both hands for the third time and smashed it from top to bottom.

This time, the marble slab did not crack, and the wrench was embedded in the marble slab. Zhao Xinli scattered some effort before pulling out the wrench. The broken position was indeed the same shape as the wrench head, and a round C-shaped shape

The sag appeared, but the shattered one was a bit powerful. It was obvious that the murderer was not as strong as Da Zhao.

"It seems that Xiao Zhou's forensic doctor was correct. The murderer smashed the deceased vertically with a wrench when he lowered his head."

"I don't understand. It's so cold outside. What can I do to make the deceased squat down honestly? It's not her attention and smash the deceased's head?"

Xu Dayuan was silent. Zhou Ning pursed his lips, looked at the wrench and then at the defects on the marble. He rushed back to the dissection table quickly, restored the deceased's scalp and stared at the defects to observe.

"The murderer smashed the deceased with all his strength, but his strength was not as strong as Da Zhao, but there was also a problem. Just like Da Zhao's move, this way, it would be inserted on the head of the deceased. He wanted to pull the wrench off.

How to do it?"

Da Zhao grabbed his head, pressed Xu Dayuan's shoulder with one hand, and kept shaking behind his head with the other hand.

"Press your shoulders or head, shake it and pull it out."

Xu Dayuan nodded, and he thought so, but his eyes widened in an instant.

"You mean clothes, there will be residues on the clothes of the deceased? I remember the test report just said that on the extract of the wound of the deceased, a male DNA that did not belong to the deceased?"

Zhou Ning smiled. It seemed that the person's subconscious actions were almost the same. He walked directly towards the evidence bag of the deceased's clothes, spread it out, spread it flat on the stainless steel table, and said while looking for it.

"I judged that unknown male DNA to be bloody, the murderer had an injury on his hand, combined with the abrasion of the deceased's nose and eyebrow bone, I suspect that the deceased had a dispute with the murderer, the deceased injured the murderer, and then the deceased was pushed down and the deceased was about to crawl.

When he got up, the murderer smashed the deceased's head from behind."

Zhou Ning said, looking at the deceased's nails. The deceased's nails were seen during the autopsy before. They were cut very short, and they were bare and wanted to cut into the flesh. Because of her profession, Zhou Ning didn't start to lose her.

I think about it much, but now I look at it, maybe this is not the reason.

Pull the LED magnifying glass light and carefully observe the fingertips. The marks of nail trimming are very neat. It is not done by using nail clippers to cut around the edge of the nail for a few times, but by cutting them directly.

Zhou Ning waved his hand to Da Zhao.

"Help me get the lumino spray and spray the dead man's nails!"

"What blood can be left after soaking in the water for so long?"

Although he said this, he kept moving. He found the lumino spray, approached Zhou Ning, and sprayed it carefully. On both sides of the deceased's nails, he could see a faint blue-green fluorescence.

Xu Dayuan also came over. After all, he had been handling cases for many years and had a lot of experience. He immediately reacted when he saw this.

"The deceased scratched the murderer, and the murderer had excellent counter-reconnaissance ability, so even when throwing the body, he would not forget to cut off the deceased's nails to eliminate all possible traces?"

Zhou Ning nodded.

"I think I can search the reservoir carefully. It is twenty meters away from the shore. Maybe I can find the weapon. He will not take it away. Moreover, the murderer's home should be in the opposite direction from the Baimahe Reservoir. After all, we always say it is far.

Throw it and buried it."

Xu Dayuan took out his cell phone and walked to one side to make a phone call.

Zhou Ning moved the LED magnifying glass to the deceased's clothes, observed the two shoulders on the back of the clothes inch by inch. When he searched for the right shoulder, there were three glue-filled things in the opposite direction. Zhou Ning fiddled with the front and side for a long time,

I didn't see what substance this was. After touching with gloves, it became a little sticky and seemed a little reflective.

Is it glue that can still be sticky after soaking in water for so long?

Da Zhao exclaimed, came over quickly, thought for a while and said.

“This is fluorescent paint.”

Zhou Ning looked at Da Zhao in confusion. He didn't understand these things and seemed to have not paid attention to where he used them. Da Zhao quickly continued.

"When the lights on the highway are shining, there is a reflective strip on the middle isolation belt, which is a kind of fluorescent paint. Of course, some dance halls and discos also make this. This thing is faster than ordinary paint, but it probably disappears after soaking in water.

The effect is that the clothes are dry, otherwise it will not be visible as fluorescent paint."

Fluorescent paint, hexagon screws, Prado tires, scratches, wrench, unknown male DNA, Shen Guanlin, Xu Zhanshan, Ma Xiangong, Shen Weijie, these known conditions continue to jump out on the transparent large screen in front of Zhou Ning.

Zhou Ning had a headache. Although he knew about an unknown DNA, he would not have to take all the men related to the deceased to compare them, which was unrealistic.

Xu Dayuan walked in. Without Zhou Ning's words, Dazhao had already said what he had just discovered. Zhou Ning looked at Xu Dayuan.

"Xu Da, I think we still have to find clues from Chen Guanlin. Although Chen Guanlin has time to witness the No. 21 Chen Guanlin, we still have to read the surveillance."

Xu Dayuan took out his cell phone, found a video and clicked on it, which was in a state of rapid playback.

"The surveillance has been downloaded. He Chunyang and the others have carefully analyzed that Chen Guanlin did have surgery during the day on the 21st. When he got off work at 6:30, he went out for 38 minutes. Then he received a call and ran back with a lunch box.

We also verified this. It was the head nurse in the operating room who informed him that he had an emergency surgery. The final time of the operation was 23:10, and the time to arrive at their community was 23:32, and he said he was walking home.

The two times without monitoring are 22 minutes and 38 minutes respectively. In such a short time, the fastest time to travel from Bayuan to Baimahe Reservoir takes 45 minutes, which I don’t think is realistic.”

Zhou Ning narrowed his eyes. He thought that they had studied this timeline many times. This time was indeed not enough to kill and throw away the body. However, when Chen Guanlin's son, Zhou Ning pulled off the mask.

"You checked Sun Ailing's car Xu Da?"

"I asked someone indirectly. It was a car that Sun Ailing's father gave her dowry. Sun Ailing usually drives it, and probably Chen Weijie occasionally drives it."

Da Zhao came over and kept shaking his head in his mouth.

"A rich man actually gave nearly one million dowry. What is his father doing?"

Xu Dayuan flipped through the text message on his mobile phone, and Zhou Ning looked closer and saw that it was written on it. His eyes lit up.

"Outdoor advertising company, Xu Da will check this car. We just found three fluorescent paint on the shoulder of the deceased. I think their company can also use the hexagonal screws, right?"
