"Brother-in-law, I'll look for it again with you, it's still early, what a pity you just gave up. ”

Ding Zexiang glared at his brother-in-law, turned his head to the exhausted Li Kewang and Wang Dongsheng and asked, "I don't know what the two of you think?"

Although the two of them were tired and their legs were sore, they were embarrassed to refuse when they saw that Ding Zexiang and his brother-in-law were very motivated. Both of them nodded, indicating that they would continue to search for another half hour, and if they could not find any new clues, they would talk about it tomorrow.

The next four people continued to expand the scope of searching, and ten minutes later, Ding Zexiang's brother-in-law finally found a clue, and he shouted excitedly: "Come here, I found the thing!

The three of them were shocked and hurriedly ran to them. With the help of the light of the flashlight, I saw a kerosene pot lying in the gutter.

As soon as Ding Zexiang was about to go down and scoop up the kerosene pot, Wang Dongsheng grabbed him: "Old Ding, this is evidence, we can't just take it up, we should find a way to keep the scene first." ”

Ding Zexiang patted his head: "Yes, yes, yes, I actually forgot about this stubble, the best way to keep the scene is to take pictures, you wait here for a while, I'll borrow a camera." ”

Cameras are definitely a rarity in this era, and most people don't have them. In order to expose this case to the world, Ding Zexiang went directly to the photo studio in the town to borrow it.

He had some friendship with the owner of the photo studio, and he didn't shirk it, so he handed over the camera to him directly, and also told him to be sure to light it when taking pictures, otherwise the photos taken would not be clear.

Ding Zexiang ran wildly with the camera, and when he rushed back to the drainage ditch, the three people who were waiting for him here made a new major discovery.

Li Kewang pulled him to the edge of the drainage ditch, pointed to a mud footprint on the ground and said: "This footprint is very new, it looks like it should have just stepped out not long ago, none of the four of us are wearing this kind of shoes, if nothing else, it must have been left by the arsonist!"

Ding Zexiang squatted down and looked carefully under the light of the flashlight. After watching it for a long time, he couldn't help laughing: "Sure enough! As long as we find shoes that match this mark, we can catch the murderer! You help me take a photo, and I will take pictures of the traces of the scene first!"

The four of them worked together and took more than a dozen photos in a row before stopping.

Ding Zexiang carefully put the camera in his pocket and said with a smile: "With these evidence, we have the bottom of our hearts, let's go back and rest today, and then go to find shoes that match the footprint pattern early tomorrow morning." ”

Li Kewang couldn't help but speak: "Shall we go to the police station tomorrow to ask for help? ”

Wang Dongsheng smiled with a confident look: "Lao Li, we don't need to increase manpower, in my opinion, it is not difficult to find the murderer at all." ”

The other three all looked at Wang Dongsheng with expectant eyes, Wang Dongsheng didn't sell Guan Zi, and then said: "The person who can help Chen Tianhou do this must be his henchman, there are not too many such people, we just need to rule it out a little, and we can determine the main goal, right?"

The eyes of the three of them lit up at the same time, and they all felt that Wang Dongsheng's words were very reasonable.

Ding Zexiang's brother-in-law was the first to speak: "If you want to say who has the closest relationship with Chen Tianhou in our factory, it must definitely be Niu Xiaogang, he is Chen Tianhou's future Chen Long's fast son-in-law, and only he is willing to take risks to do this kind of thing!"

Ding Zexiang nodded again and again: "What you said is reasonable, Niu Xiaogang is not only Chen Tianhou's fast son-in-law, I also heard that he also did bad things with Chen Tianhou, this guy shouldn't be aware of the problem of footprints, those shoes should still be in his home, in order to avoid long nights and dreams, I suggest that we go and control him now." ”

Wang Dongsheng and Li Kewang already knew the relationship between Niu Xiaogang and Niu Xiaoqiang, and they didn't know what Niu Xiaoqiang's attitude was, so they persuaded Ding Zexiang to stabilize first.

Ding Zexiang was a little incomprehensible about this, "What's wrong with you, why do you have to delay time?"

Li Kewang exchanged glances with Wang Dongsheng, and then said with a haha: "Lao Ding, this matter is still a bit hidden, we must deal with the hidden situation to determine whether to do it to Niu Xiaodong, or else, you and your brother-in-law will go to Niu Xiaodong's side to monitor first, I will go back to discuss with Lao Wang, and wait until we discuss the results, and then go over to find you." ”

Wang Dongsheng said: "Don't ask more about the specific situation, I will naturally tell you when the time comes, so it's decided, let's go our separate ways." ”

Ding Zexiang looked at the two of them and felt more and more puzzled. But since both of them have talked about this, it is not easy for him to hold on.

I saw him nod: "Okay, just do what you want." ”

The four of them split into two groups and each acted separately. Ding Zexiang took his brother-in-law to the dormitory building where Niu Xiaodong was located, and monitored Niu Xiaodong's movements downstairs. Li Kewang rushed to the cave factory with Wang Dongsheng to ask Niu Xiaoqiang's opinion.

Niu Xiaoqiang is studying computer technology.

He used to read books every night, but since Watson told him about it, he spends his evenings studying computer technology, and as for reading, he only spends two days a week doing this.

When Wang Dongsheng and Li Kewang arrived at the cave factory, Niu Xiaoqiang was writing a simple program based on Watson's handwritten textbook. He immediately turned off the computer and walked out after hearing the shouts of the two.

Niu Xiaoqiang didn't expect the two to come to the door again after leaving for a few hours, and he couldn't help asking, "...... are the two of you?"

Wang Dongsheng lowered his voice and briefly told what happened in the factory. Niu Xiaoqiang frowned after hearing this: "This matter was really done by Niu Xiaodong?"

Li Kewang nodded: "According to our inference, his suspicion is the greatest, after all, his relationship with Chen Tianhou is there, of course, we have not yet carried out the final verification, so we dare not really identify the arsonist as him, Brother Xiaoqiang, what do you think about this matter?"

Niu Xiaoqiang's question just now was said to himself, in fact, he had already accepted the arguments of the two, but he didn't expect Niu Xiaodong to be so bold, so he would talk to himself.

After a moment of silence, Niu Xiaoqiang instructed: "The two of you will go to the office in the factory first to wait for the news, you leave me the phone number in the office, I will go back and ask the opinions of the family, and after asking clearly, I will call you immediately to explain the situation." ”

The two did not hesitate and immediately nodded and left.
