After speaking, Jiang Chonglang squatted on the ground, took out a metal detector from the backpack behind him, and carefully searched for something around this big stone, Han Yuchao looked at him like this, and said, "Brother Chong, are you looking for bullet shells?" ”

"Yes, if you can find the bullet casing, take it back and measure the marks on the bullet and the bullet casing. It will be possible to determine whether the two bullets were fired from the same gun. ”

In pyrotechnics, although guns can be mass-produced, the rifling in the chamber of each gun is different. Therefore, the most common way to determine whether two bullets were fired from the same gun is to check whether the marks on the bullet casing are the same as the rifling wear marks in the gun. The rifling of a gun is like the fingerprint of each gun, which determines the relationship between each bullet and each one.

It's a pity that a few people took a metal detector to look for it on the ground, and after probing for a long time, they still found nothing, "It seems that the murderer is still quite smart and has a certain anti-reconnaissance ability." Knowing that the bullet casings would fall to the ground after the shot, he took the bullet casings away without leaving us a single piece of evidence. Ye Lili sat on the ground and said disappointedly, while taking off the helmet on his head.

"There's no way any murderer can't leave a clue at all, unless he flies over. Besides, didn't we collect a lot of shoe prints, and take these shoe prints back for comparison. You might be able to determine his physical features. Han Yuchao comforted, and by the way, brought the helmet back to her head.

"I don't wear it anymore, I'm dying of heat. It's up to you, so let's wear helmets. Ye Lili asked for another helmet to take it off.

"Bring it on, what if the murderer is right next to us, you will be honest with a bullet flying towards you. I'll tell you: bullets don't have eyes. Han Yu held down the helmet for him.

Jiang Chonglang turned his head, looked at the two of them and said, "Lili, look at our Xiaochao, patient and considerate, down-to-earth and honest in work." In the words of the Internet, it is a standard 'warm man'. Lili, let me tell you, I have walked through this village, but there is no such shop. So, shoot when it's time to make a move, hurry up and take down our Xiaochao, Xiaochao, you are the same, you see what a good girl you are, don't miss her. ”

Hearing Jiang Chonglang say this, the two of them were stunned for a moment, glanced at each other, and then both showed disdain for each other. Han Yuchao said first: "Leave, everything is good, but it's not good at all - no femininity, masters." ”

When Ye Lili saw him say this, he also retorted: "Brother Chao, you are good at everything, but you are not good at all - lack of manhood." ”

Hearing him say this, Han Yuchao was very dissatisfied: "Why don't I have manhood, you talk about it, you talk about it." ”

"Brother Chao, it's not me talking about you, look at you. When I went to the scene of the garbage dump, I had to prepare so many masks, for fear of getting myself dizzy, you see that I am not a little girl like you; And last time it was on the highway not far away, I don't know who was nervously hiding in the car and didn't dare to come out. You say you don't lack manhood. ”

"Hey, I'm responsible for myself and my relatives, human life is only once, how can I not pay attention to it. True. You said that if you have a good one, you said how sad and sad your parents should be. You don't know how sad our family was when my brother died, can you understand this, do you understand? ”

Hearing Han Yuchao say this, Ye Li couldn't speak. Han Yuchao found that when he talked to Ye Lili several times, as long as he talked about his parents and elders, Ye Lili's mood would immediately drop to the bottom. Han Yuchao wanted to ask what was going on, but he didn't know how to speak.

Compared with Ye Li's heartlessness, there is also an unknown sad past. Everyone has a period of sadness that they want to hide but want to cover up.

In this way, a few people returned to the police station, and Xue Ran and Xu Meng also came back from the "City of Bliss", Xue Ran said with a smile: "Team Jiang, as soon as we walked to the door of the clubhouse, the security guard there grabbed our hand and said, 'Comrade policeman, you are here. Recently, because of these two homicides, the road leading to this place has been blocked, and the number of guests has decreased a lot. Now they can't make ends meet here, and they're about to go out of business. ”

"yes, hahaha. Let me laugh three times, retribution, retribution. The last time I went, the security guard was swaggering and treated himself like a superior person. I didn't expect to go die so soon. Cool, cool, cool. Jiang Chonglang said as he patted his thigh excitedly.

Seeing that she was so excited, Zhang Lanshan ran away and patted him on the head to make him sober up: "Normal, what about work hours, don't be like taking medicine." ”

Xue Ran continued: "After that, we went in and met the owner of this club, whose surname was Zheng. He told us that Xue Jingfan is also a frequent visitor here, and he usually doesn't work, but he comes here when he is leisure. As for what he will do after here, Boss Zheng is silent. Of course, we can guess one or two. ”

So it's no wonder that Xue Jingfan wants to stop on the highway, smoke a cigarette and take a breath to rest. It must be too hard work in the clubhouse, and the kidneys are too weak. Xu Meng answered.

After everyone laughed for a while, Xue Ran continued: "Team Jiang, it seems that these two murders have a great impact on the business of the 'City of Bliss', because it is said that the road where the crime occurred was originally specially built by those rich people for convenience, and now that we have closed the road, if we want to go anywhere, we need to make a big detour, and we also drove for a long time today before coming back." ”

"They deserve it, these rich people live extravagantly, are drunk with money, and sing every night, maybe there will be something unsightly in them. Didn't you see what the uncle who led us the way today said, in order to build this clubhouse, this road was built: how much money was spent, how many trees were cut down, and the ecological environment here was destroyed, which is really unkind. It would be best if it could go out of business. Ye Lili said indignantly.

"Build clubs, build roads, and destroy the ecological environment." Listening to Ye Lili's words, these words flashed repeatedly in Jiang Chonglang's mind: "Maybe our investigation is in the wrong direction, we started by investigating the social relations of the deceased to see if he had any enemies and killed people because of revenge, this is indeed the most normal way of thinking." But what if the murderer and these dead people have no grudge, but for some purpose, choose to kill without a goal? ”
