After the meeting, the Zhang Brigade and his group could not rest after studying, and had to take a fixed-point watch to wait for the visit. What is a Spot Visit? It is to visit people at a specific place and at a specific time according to the circumstances of the case, which is a common method in the investigation work.

This group of people, distributed in ten points in the township, is basically a transportation hub location, and visits pedestrians. By 6 o'clock in the morning, a total of 16 people were interviewed, but all of the interviewed people said that they had not seen or encountered any suspicious people or objects on the night of the crime, and some of them had not appeared at all in the early morning of 26 July. When the sun came out, the investigators were exhausted one by one, dragged their heavy steps and hung their heads back to the police station, and after a simple breakfast, they put themselves into a new job.

In the morning, the technical team arranged a special person to the provincial department to do fiber inspection, and the fingerprint screening work was also in full swing, all the people who may enter the scene of the case have taken fingerprints, and the people who may have touched the items inside have also been found one by one, and fingerprints have been printed for comparison and screening. The blood taken at the scene, after testing, found that there was no other blood type except for the two parties.

In the afternoon, Liu Chuanzhi, a footprint expert from the provincial department, rushed to the scene.

Liu Chuanzhi did not want to come to the scene after asking about the scene and the disposal of the scene on the phone, because he believed that the measures that should be taken by the technical departments at the county and city levels had been taken, and there was no need to come, so he refused to come.

Lao Zheng, the captain of the technical team, was anxious: "Expert Liu, my expert Liu, you have to work hard no matter what." ”

Liu Chuanzhi: "Captain Zheng, it's not that I won't come, I also listened to what you just said, you handled it very correctly, and there is nothing missing." What am I going to do, am I going to repeat your work? Is it necessary, you say?

Besides, there are so many things in the provincial department, I have come a long way, and I have gone to you to repeat your work, and I have eaten too much. I can't finish the affairs of the provincial department.

You have to understand me! We're not strangers, are we? We've been friends for years. "Expert Liu patiently did Captain Zheng's ideological work, the purpose was not to come.

Captain Zheng: "Expert Liu, I understand everything you say, and I can understand you." However, you see, although we have thought of a lot of ways, we still have not extracted fingerprints, and the footprints are so mutilated, the leaders are very dissatisfied. Director Tang made it clear at last night's meeting that he wanted to invite you over. You are a big expert in the provincial department, and the leaders still trust you very much. One sentence you say will work better than a hundred of us. You also know that the grassroots level is such a level, we only have such a ability, and we have been friends for so many years. I have difficulties, I have difficulties, I don't look for you, who am I looking for? You have to understand me, too. Come on, come on! ”

Liu Chuanzhi: "Lao Zheng, I really convinced you, and you really know how to do ideological work." Okay, I'll fight this old bone, work hard, and come to you to have a look. But let me make you clear first, I don't eat at your place, you drink too much. I'm afraid, I'll leave after reading it. ”

Captain Zheng: "Where is it, I didn't have no choice but to find your brother, thank you for your understanding and support." As long as you can come, you can do whatever you want, it's always okay, right? ”

Liu Chuanzhi: "Haha, I love to hear this sentence." You wait, I'll leave right away. ”

After Liu Chuanzhi came, he took the electrostatic photocopying method to carefully deal with the ground on the site, but did not deal with the footprints well.

After dealing with it and exchanging the situation with Director Tang, Liu Chuanzhi rushed back to the provincial department, where there were more cases waiting for him to deal with.

By the time the meeting was held again at 12 o'clock in the evening, there was no progress in the groups, Director Tang's face was even more ugly, and the meeting dispersed in depression.

The group of Zhang's team continued to wait for the visit at a fixed point, and the hard work paid off, or the sincerity of the gold and stone was opened, and finally met a person who worked in a nearby concentrator!

After inquiry, he generally passed near the scene at about 1:30, and at about 1:30 a.m. on the 26th, he walked slowly to the concentrator alone, and suddenly saw three people running out of the direction of the supply and marketing cooperative, running to the east of the town. Surprise me! Since I was in a hurry to go to work, I didn't care too much.

After hearing about this situation, Team Zhang immediately invited this person to the police station, and Director Tang heard that there was a situation, so he and Director Zhang quickly rushed over.

The questioning was conducted in accordance with the procedure.

Q: What is your basic situation?

Answer: My name is Ke Qingping, male, 29 years old, from Kejiadu Bay in this town, and now I work in Zhendong Concentrator Factory.

Q: Tell us about your situation in the early hours of yesterday morning?

A: Okay. I woke up at 1 a.m. yesterday, and after a quick freshening, I left for work. At about 1:30, I arrived at the town crossroads, and I was about to walk from the south to the concentrator, when suddenly three people ran from the direction of the supply and marketing cooperative, and the speed was quite fast. I didn't expect someone to run out in the middle of the night, which scared me, and I whispered, "What are you running in the middle of the night?" "Then I continued to go to work, it was two o'clock in the factory, I looked at the time, from the town to my factory, I usually take about half an hour, so I deduced that the time I saw these three people should be 1:30, and then I went to work in the factory. I was about to go to work again in the early hours of this morning, but I was stopped by you. You should finish asking early, the factory is still waiting to go to work, otherwise your wages will be deducted.

Q: Don't worry about going to work, we will contact your factory leaders, please cooperate with our investigation, okay?

A: As long as the factory leaders have no opinion, I have no opinion.

Q: Do you see the characteristics of these three people?

A: I didn't see this clearly, but from the speed of running, the age should not be very big, because the speed of running is quite fast, in addition, these people should be about 1.70 tall, because I am also 1.70 meters, these people look about the same height as me.

Q: How can you be sure that it is 1.70 meters tall?

A: I was only about 10 meters away from them, and although it was dark and there was no light, I guess they were this height from the shadows.

Q: Did these people carry any items on them?

A: I didn't pay attention to this, they ran very fast.

Q: Where are they running?

A: I ran in the east of town.

Director Tang saw that he couldn't ask any key points, so he lost interest, so he withdrew and left with Director Zhang.

While calling someone to question Ke Qingping, Team Zhang arranged for someone to investigate what he said.
