Because he obviously suspected that Qian Yongchang had a problem, but he couldn't find any clues, could it really be compared with what Du Wenbin said before, take out all the shoes of Qian Yongchang's family one by one, but if you do this, it feels very far-fetched, Qian Yongchang's shoes are all bought in this town, and his shoes are not the only pair.

And after comparative investigation, the footprints they got at the crime scene were very clear, very large, but newly bought shoes, there were no signs of too much wear, if there were traces of wear on the soles, you can also deduce how old the person is through this wear and tear.

After all, the focus of each age group, the focus of the feet is different, and the age of the person and what special posture he usually has when walking can be deduced through the degree of wear, and I don't know if this group of arrivals is too strong in anti-reconnaissance ability, they all wore new shoes, even if they left footprints at the scene, they did not provide them with many clues to break through.

"No, there is definitely something wrong with this matter, they are not immortals, how can they not leave traces, but we have not found it, you think about it, what method did the suspect use to stun so many people? It must have been a drug or ether or something, but we didn't detect it at the scene.

There must be other methods, details, the most important thing is the details, it must be that we have missed some of the most critical details, so that we still have nothing to find, we have to investigate, to inquire again, and to ask them all the experiences when they bought and sold buns with Qian Yongchang that night, no matter how big or small. ”

Qin Shanhai stretched out his hand and patted the table and said to Du Wenbin, Du Wenbin frowned and wanted to say something, but looking at Qin Shanhai's serious expression, he swallowed back his words, in fact, this matter has been investigated countless times so far. But there are still no useful clues from their words, but Qin Shanhai is also reasonable, sometimes solving the case is to start with some details, see the big from the small, and gradually investigate clearly.

Du Wenbin just asked about the process roughly and wrote it down, if there is anything greasy in it, maybe he can find any clues from it, so as to investigate further.

"Dahai, do you see if there is such a possibility, when Qian Yongchang was buying and selling buns with them, maybe he smeared the comatose medicine on his hands, and then took the opportunity to smear a few of the buns, and then happened to be eaten by them, or Qian Yongchang put something in the sale, and they didn't pay attention. Du Wenbin thought about it carefully and said.

Qin Shanhai nodded, he did have this conjecture, when investigating this case before, they almost took all the food and drink from the homes of the more than a dozen stolen villagers to be tested, but whether it was the water they drank or the water they used, or even anything they had eaten, they did not find any medicine that stunned them.

That's why they focused their investigation on the buns, but the investigation found that there was no problem with the buns, but Qin Shanhai was sure

There is definitely something wrong with that bun, or there is definitely something wrong with Qian Yongchang, who sold the buns, and he definitely played a major role in this incident, but there is not enough evidence to arrest him at the moment.

Otherwise, why did the dozen or so stolen families eat Qian Yongchang's steamed buns, and then they fell asleep unconscious, even if there was a big movement, they didn't wake up until the next day, and they didn't find out that their home had been stolen until the next day.

This is definitely not a coincidence, there must be something they didn't find, so Qin Shanhai decided to focus the investigation on the buns, but the previous inspection did not extract the comatose drugs from those buns, but it doesn't mean that some other things didn't happen in the process, so Qin Shanhai decided to ask people to ask the stolen villagers again.

According to the information provided by those who were stolen, analyze it bit by bit to see if you can dig out some of the more critical issues from it.

Du Wenbin glanced at Qin Shanhai, pondered it carefully, and found that it seemed that there was only one way to continue now, otherwise he really didn't know how to continue the investigation.

Du Wenbin said hello and took people to continue the visit, as soon as the front foot left, Lao Zhongtou actually came to the police station, it seemed that Lao Zhongtou was recovering well and was very energetic.

Some time ago, Lao Zhongtou's injury was stable and he was about to be discharged from the hospital early, Zhong Guotao understood his grandfather's temper, and let him be discharged from the hospital and taken home for recuperation when he saw that he was fine.

After the injury stabilized, Zhong Guotao took a lot of people out to study together, Qin Shanhai took care of the old clock as long as he was free, and the cold and warmth can be called meticulous, the old bell didn't feel that there was anything wrong, and accepted it calmly, in the old clock's opinion, Qin Shanhai was like his grandson Zhong Guotao, he was his own child.

I came home after work a while ago, and I haven't seen anyone in the past few days, so the old man was a little worried, and when he went out to inquire, he learned that there was a strange case recently, and a lot of fakes were stolen in the town overnight, and the thieves came and went without a trace, and even the police had no way.

Lao Zhongtou is a security officer, he knows this case, the police station must have been very busy recently, and he is so busy that he can't even take care of eating, Lao Zhongtou is a person who can't be idle, and his injury is almost healed, so he made something delicious and sent it to Qin Shanhai, and by the way, he learned about the theft.

Qin Shanhai hurriedly welcomed Lao Zhongtou into the office and poured him a cup of tea.

Old Clock Qin Shanhai frowned, knowing that he might not have the results of the investigation now, he sighed and said: "I heard the rumors of the people in the town that the thieves said that they can do anything, but I know that it is nonsense at all! I think they are pretending to be ghosts at all!"

After recovering from a serious illness, the old clock's words were still sharp, Qin Shanhai's heart was slightly settled, knowing that the jealous and hateful old bell was back again, and as long as Shanghe Village was there, he would be a little more stable.

Qin Shanhai smiled and said: "Zhong Ye is right, take your time, you will definitely be able to get to the bottom of it, by the way, how is Guotao's side?"

Seeing that Qin Shanhai didn't seem to be willing to discuss the case, Lao Zhong felt that it was okay

can be the reason why the case should be kept secret temporarily, so let's talk about another matter, Zhong Guotao called home several times before, and talked about the situation in Yanjing.

"It's very smooth, it's good to eat and live there, everything is tired, I have to study for ten hours a day, the time is about the same, it shouldn't be long before I can come back from Yanjing, I heard that he also saw a lot of fresh gadgets in Yanjing, and wanted to buy it back and bring us some." I also bought you a gift, this kid has a heart, I thought he didn't understand these before, after going out, he may have seen a long time, and brought gifts to those good friends, but I don't know if his money is enough to spend. This kid called me, full of good, I listened to it and felt a little weak, knowing that he was comforting me, but I was very worried about whether it was really good or false, for fear that he would encounter something difficult there, and it would be difficult to find someone to help him. ”

Speaking of this, Lao Zhongtou's face couldn't help but show a trace of sadness, Qin Shanhai hurriedly relieved: "Guotao is not the kind of person who bites all the hardships and doesn't say anything, he knows the seriousness of the matter, they are going to learn technology, and if they don't have contact with the outside world, there will be nothing wrong, after all, it is a big capital, and the quality of people is high, you can rest assured." ”

chatted with Lao Zhongtou for a while, and Lao Zhongtou said that he would continue to be busy and go back first, in fact, Lao Zhongtou came to this trip, Qin Shanhai knew that Lao Zhongtou was worried about Zhong Guotao, so he came to tell him this.

There were so many accidents before, Lao Zhong was a little suspicious, and even Qin Shanhai himself was a little uneasy, always afraid that something extraneous would happen.

Thinking about it carefully, Lao Zhongtou's worries are not unreasonable, there are more people and more things, even if Zhong Guotao has any difficulties over there, he will definitely tell himself, but he may not necessarily tell Lao Zhongtou, I am afraid that he will be worried, I heard Qin Shanhai say that Zhong Guotao did not call him, and Lao Zhongtou was slightly settled in his heart.

After sending off the old hour, Qin Shanhai originally planned to go out, but he didn't expect to meet Li Yingxue.

Li Yingxue blinked her eyes wide, holding a snow-white notebook in her hand, obviously to do a follow-up interview.

Seeing her work card hanging around her neck, with a serious appearance, Qin Shanhai felt a little funny, she was really a very positive and serious person, and she was very responsible for what she should have promised.

After the two of them sat down, Qin Shanhai couldn't help but say what was troubled him, Li Yingxue frowned, and said helplessly: "I didn't expect this case to be so complicated, I thought that I could find clues from it, but I couldn't find anything, I don't blame you for being so worried, I think even if Liu Suo goes into battle in person, there is no good way." ”

Qin Shanhai smiled bitterly and didn't say anything, Li Yingxue blinked her eyes and continued: "Actually, when you say this, I also think that this Qian Yongchang problem is the biggest, if he didn't do anything, why did he show that smile? And why did he sell buns from more than a dozen houses, and something happened to those dozen or so houses, if this thing was not done by him, many doubts could not be explained, which can only prove one."

The problem is that this matter must have something to do with him. It's just that we haven't found it for the time being, there must be something wrong with this person, you might as well control him, and ask carefully, I think since he has a criminal record, you have enough reason to suspect him. ”

After Qin Shanhai heard this, his face was bitter, and he was about to say something, but Li Yingxue waved his hand, understanding what Qin Shanhai meant, in fact, it was quite easy to arrest him, after all, many places in the investigation of this matter were related to Qian Yongchang, and there was every reason to summon him over temporarily and ask some questions.

But even if he is brought to the police station, because there is no definite evidence, it is impossible to conclusive the case, and the existing evidence cannot prove that Qian Yongchang is a suspect at all, but can only prove that Qian Yongchang has something confusing, after all, his eyes cannot be used as evidence.
