Chapter 346 The marks on the palm

Following Zhou Ning's gaze, the two of them looked over.

Sure enough, there was a dark brown mark on the inside of the top of the kennel, with four fingerprints on the edge.

Sun Gaotiu didn't need to give instructions, so he quickly went up to collect fingerprints. This angle happened to be the inside of the iron sheet, completely blocking the erosion of wind and rain, and it can be said that it was quite complete.

Xue Yang compared the cement footprints and said happily to Zhou Ning:

"The residual cement-sole pattern is the same as Chen Gang's footprints, and the stress point is exactly the same. I don't know if this blood stain can match the blood stains on the broken porcelain pieces he smashed. If it matches it, it can be confirmed that it is Chen Gang's DNA."

Zhou Ning didn't say anything, looked up at the wall.

As expected, the wall was like the one who investigated Wang Hongzhan's house before. There were glass fragments on the top and inserted on the wall. It was almost impossible to turn over such a wall with bare hands without leaving any traces. It was necessary to check it out.

However, there seemed to be a lot of blood left on the inside of the top of the doghouse. According to the amount of broken porcelain pieces and blood left in the old house, the cuts would not be very serious. Did Chen Gang still have any injuries when he fled?

Unable to figure it out, Zhou Ning didn't think much. Seeing that the two of them had finished extracting, someone had already sent a ladder. Yang Xuetong climbed up and kept checking on the wall, took a few samples, and then looked at Zhou Ning.

"There are few traces left on the wall. If you find traces of suspected blood stains everywhere, you need to compare them in the laboratory. However, boss, Chen Gang was shot dead when he climbed over the wall. How did the other kidnapper leave?"

Zhou Ning looked around the wall. Although the house had been idle for twelve years, the courtyard wall was very complete, about two meters high, and no place had collapsed. When he just came here, he saw that the wall near the road had been painted with a mobile company advertisement.

"I remember Director Sun said that when they were about to surround the place, someone seemed to see a black shadow climbing over the wall and leaving, but they didn't think so much. After all, Chen Gang was the only one who was going to be arrested at that time. He didn't find the ransom, so he felt that there might be a second person involved."

Yang Xuetong waved his hand to Sun Gaoti.

"Boss, go and see Da Zhao and the others. We borrow two more ladders. Since we have crossed the wall and left, we will sift it up no matter what. I will take a few more samples. At worst, I will be scolded by Sister Cui. It is not a big deal. It is impossible to get hurt on the wall."

Zhou Ning nodded. He knew that although this was a stupid method, it was the most effective.

"Okay, you two should be careful. Let Director Xu send someone to walk around the outside walls and collect all the glass fragments scattered on the ground. Since you are looking for a needle in a haystack, it's not that bad."

Sun Gaoti was very happy and waved his hand to Xu Dayuan and shouted out what Zhou Ning said word for word. Zhou Ning rubbed his nose and quickly entered the second house where Da Zhao and the others were.

As soon as I entered, I found that the light was very dark here. There was a small blue glass window on the east wall. The glass was quite complete. The room had a complete bed, table and wardrobe. The only chair had one less leg. Da Zhao leaned his head into the wardrobe. Liu Yongxin and Zhu Xingxing stood in front of the bed and didn't know what to look at.

Zhou Ning walked over quickly and observed the room. He saw two deep scratches on the table, with blood on the edges. This discovery instantly connected Zhou Ning to the blood on the top of the doghouse.

Could it be that Chen Gang and the kidnappers had internal conflicts and were injured during the dispute? But in Cheng Xinghui's memory, the kidnappers left alone. When the police surrounded the place, Chen Gang hid him and fled.

Wait, according to the kidnapper's urinary nature in the 4/14 kidnapping case in 2004, the first step to get the ransom was to kill people to silence them. Even according to the time of death, it may be that the person had already killed before the ransom.

Then in the 2000 2000 kidnapping case, he came with a ransom and wanted to kill someone to silence him. However, in this process, perhaps Chen Gang softened his heart, or perhaps he heard the sound of the police surrounding him interrupting his plan, so he fled in a hurry.

The more I think about it, the more likely Zhou Ning feels it is.

The blood stains in Chen Gang's old house were quite complete, and they would not be kept so clear if they swept across the ground. Perhaps it was not left unintentionally. There might be the first dispute between Chen Gang and the kidnappers.

After the child was transferred to the Liyuan and received the ransom, the kidnapper did not convince Chen Gang. Although he had a second argument, the kidnapper did not kill Chen Gang, but left with the ransom. If he had taken action at that time, he might not have been able to escape that time.

Seeing that Zhou Ning was still moving, Da Zhao made a shushing move towards Zhu Xingxing. He knew that Zhou Ning must have thought of something.

Zhou Ning put on gloves and pointed at two traces on the table.

“Have you taken a photo and sampled it?”

Da Zhao nodded, and Liu Yongxin came over.

"At that time, the investigator heard the child crying and came in to find Cheng Xinghui. The man was shot dead. We did not investigate the scene again. When we found that the ransom was not found, we did not find any traces left in it."

Zhou Ning observed these two traces. They didn't look like cut by a knife. They were deeply grooved. The wood on the table was defective and looked like it was scratched by a fingernail.

Da Zhao came over and held the swab.

"Why would I take the table back in Zhou Xiaozhou? These are all traces from twelve years ago. I'm afraid the sampling is not standard."

Liu Yongxin waved his hand and used a scalpel to pick out a piece of debris from the corner.

"That's fine, but do you think this trace is a bit strange. I think it's like a mark cut by a grooved knife."

Zhou Ning looked up at Liu Yongxin and paused slightly.

"Can the triangular bayonet do it?"

"Don't guess. I've got a triangular bayonet for someone. Then we can do an experiment. The wood on this table is really soft. You can see if you can mark the marks with your nails. Let's go back and do an experiment to see if the military sting can create such marks."

Zhou Ning nodded.

"The table is taken back, are there any other discoveries in the room?"

Da Zhao pointed to the survey box and lifted up a layer, revealing several bags of physical evidence inside.

"Something came out of the wardrobe. There was a L-size Spring and Autumn work jacket with four words embroidered with rainbow fireworks. According to Cheng Zhi's previous description, Chen Gang was very thin. This should be his clothes, but I don't know why he threw it in it."

Liu Yongxin hugged his arms and narrowed his eyes slightly.

"Do you remember that there were kidnappers' shoe prints left outside the wall, and the shoes were the same as Chen Gang's. Da Zhao also inferred that the man's height and weight, and he could wear the same shoes. I feel that the clothes were also Chen Gang's. Maybe it was because of this that the child was changed into the same clothes and he got the child out."

Da Zhao looked dazed and kept gesturing his fingers.

"That makes sense. The two of them covered up and pretended to be alone, took the child out, and first arrived at the old house of Chen's family. Perhaps the kidnapper wanted to kill someone at that time, but was stopped by Chen Gang. Chen Gang even regretted his cooperation, but the kidnapper threatened Chen Gang and asked him to wait in the Liyuan.

The kidnapper went to get the ransom, and then returned to the Liyuan. Here the kidnappers wanted to attack the child for the second time. As for the bloody dispute, Chen Gang's wound collapsed, the kidnapper ran away with the money, and waited for the police to approach, Chen Gang was thinking about escaping, waiting for Uncle Liu, was there any injuries on Chen Gang's hands at that time?"

Liu Yongxin slapped Da Zhao and gave him a blank look.

"You think my computer? Didn't the file be sent here, you can scan it, and you'll know it just by taking a look?"

Zhou Ning had already opened his phone and found the picture of the file. There were not many photos of the deceased being shot dead, and the angle was quite good. After looking through a few pictures, he found a picture of the unfolding of his hand. There was gauze in the palm of his right hand, but part of it had been loosened and two cut marks on the palm of his palm could be seen, very deep cut marks.

There was a scale next to it. Da Zhao quickly converted it and gave the two cut marks a distance of 0.95 cm. Seeing this result, Da Zhao's eyes lit up.

"We have checked before that the diameter of this 56-type triangular bayonet is 1.8 cm, divided by 2, the radius is 0.9 cm, the circumference is 2.826, and the spacing between the three edges is about 0.942 cm. If the skin on the hand is loose, then this spacing is completely possible. Chen Gang grabbed the triangular bayonet and was cut."

Liu Yongxin smiled and patted Da Zhao's arm.

"It's okay. Elementary school mathematics is good. Please send samples for inspection. We now know a lot of conditions. We just don't know what the relationship between Chen Gang and the kidnappers is. If we find the DNA of unknown men in these samples, we will make a lot of money."

Da Zhao blinked, raised his hand, and counted on his fingers.

"It is indeed known that there are many conditions. The kidnappers are between 175-178, have medium figure, and weigh between 140-150. They have anti-reconnaissance capabilities and can completely escape the encirclement of the police. This is not something that ordinary soldiers can do.

By the way, there is also the fact that he has contacted special lubricants for ships, which has a very different relationship with Chen Gang. According to the cruel state of torture and killing the three members of the Zhu family, the kidnapper is a cruel and ruthless person.

However, he did not attack Chen Gang, but just escaped with the ransom. Logically, leaving Chen Gang's living habit is the biggest threat to his safety."

Liu Yongxin nodded, and Zhou Ning touched the scratches on the table.

"The analysis makes sense. This kidnapper must be very familiar with Chen Gang, and he can tolerate Chen Gang's excessive demands and even touch the bottom line of the kidnapper. After all, he left alone because of his greatest trust in Chen Gang.

As for who is this kidnapper? Does the Chen family know? It depends on the interrogation of Director Xu and others. I didn’t know that Chen Gang was adopted before, and these two families can still be fooled. Now there is no need to hide it. We will go back to inspect first and conduct relevant experiments."

Zhou Ning touched the table and looked at the wardrobe again.

"Take the table back. Chen Gang had a cut on his hand, which means that the dispute here was very fierce at that time. Perhaps the kidnappers also had injuries on his hand. All the extractables on the outside wall were extracted, and all the things in the wardrobe were put back."

Da Zhao nodded and opened the drawer below the wardrobe. A dark green bag suddenly appeared, and the red five-pointed star on it was very conspicuous. Looking at the bag, Zhou Ning paused.

"Wait, Cheng Xinghui said that the man with a hoodie has a bag like this. Didn't he say he was carried away with a ransom?"
