"Where's Team Xu?"

Hao Lao crooked to the scene of the crime and shouted first, Da Yang was squatting next to the corpse in the living room, surrounded by bloodstains.

"Checked the surveillance, what's wrong with you?" he said.

There were quite a few people in the room, some doing scene investigations, they were holding cameras to film everything that could be used as evidence, and some were doing behavioral reasoning, and the group was like a psychopath, and the two of them demonstrated the whole process after the murderer entered the room. And Hao Lao Crooked and Da Yang chatted with each other, not at all like they were at the scene of a homicide, like a construction worker at a height of more than ten meters, or like a group of local tyrants playing a game of golf and casually getting thousands or tens of thousands of courses, not taking the environment in front of them seriously at all.

"Don't mention it, that kid in our family was beaten up at school, and he has to take an hour off tomorrow morning, you said that when we go to school, how can there be so many things?"

There is no need to ask how the deceased died, judging from the high-speed splattered blood stains on the walls, the damage caused by such marks can only be a gunshot, and it must be a shot at close range.

The identification of blood stains used to be done by Chen Da and the people who investigated the scene, and the types are divided into three types, the first is low-speed splash bloodstains, which is relatively rare, such as the murderer keeps hitting the deceased's head with a blunt object, causing the last few strokes after large-scale bleeding, and when there is not much plasma, the blood splash speed caused by the small blood vessel pressure is greatly reduced; The third type is the high-speed splash bloodstain, like a close-range shot, and the bullet marks on the deceased's head prove the source of the blood stains on the wall, and the bullet hole at the center of the splash blood stains indicates that even if there is no body and bullet casings at the scene, the deceased's death method can be verified through the bloodstains.

"Yo, I thought your children had to be five big and three rough, and they would beat other people's masters wherever they went, so there were times when they were beaten. ”

Xiao Liuzi's ridicule caused a room of laughter, and almost everyone who knew Hao Lao Crooked opened their mouths regardless of whether they knew Hao Lao Crooked.

Hao Yong took a step forward, and just saw a pair of men's blue slippers placed crookedly next to the shoe cabinet, looked down several times, and then turned around and walked into the house, there was no trace of tearing inside, and there was only a teacup on the coffee table that had not had time to pour water with tea leaves. Hao Lao Crooked continued to walk forward, walked to the teacup, looked at the corpse that had fallen near the coffee table, and then looked at the high-speed splattered blood stains on the wall of the living room, and said with a sigh of teeth: "It's that simple?"

Da Yang answered: "No, when the murderer came in, the heroine should be very happy, she entered the house and began to make tea, and before she could pour water, the bastard who had changed her shoes and walked in stood behind her, and when the deceased reacted, he turned to face the murderer, he had already shot." ”

It sounds like a process that can be judged without much analysis, but if you think about it carefully, you will immediately feel that the murderer is cold-blooded. The girl lying on the ground is like a flower, about thirty years old is the best time for a woman, she has a mature temperament, her face is not old, not to mention that she is ecstatic about the arrival of the murderer, but at this time you suddenly raised your gun and said that you would be killed?

It's like smoking a cigarette on the road and crushing an ant with the sole of your shoe?

Or is it not personally?

Hao Lao stretched out his hand and scratched his hair: "Brothers, why do I feel awkward about this scene?"

"Who isn't awkward?" said the colleague in charge of the scene investigation: "It's the same as picking up the murder before, there are obvious traces of cohabitation with the deceased in the house, and the annoying thing is that you can't even find the fingerprints of the deceased at the scene, and the one that is cleaned up is called a clean, clean and even the hair that can be seen everywhere in the woman's house I didn't find a one." ”

"No one in the neighborhood heard the gunshots?"

Under Hao Yong's question, Da Yang spoke: "I have asked, and they said that they heard strange sounds, but they didn't know if it was gunshots, anyway, it was not the same as the sound on TV." Because of this strange sound, no one cared...... "8090."

"Oh no, this grandson must have hit the silencer. ”

When it comes to weapons and equipment, Hao Lao is an expert, the difference between this silencer and the TV is that the silencer allows the gunpowder gas in the barrel to expand relatively slowly before spraying out of the muzzle, similar to the difference between opening a can and slowly opening it. Therefore, the sound of pistol firing can reach 60 decibels at most after installing a silencer at 80-100 decibels...... As for decibels, generally speaking, when the outside noise reaches 40 decibels, it is considered a quiet environment, 70 decibels will make people start to pay notice, if it exceeds 150 decibels, people will feel obvious discomfort, and the sound of a rifle can reach 100-120 decibels. This is the reason why when a gunshot is fired, the police will immediately ask the neighbors to confess and ask if they have heard the gunshot.

The problem is that in China, a country where guns are banned, let alone guns, even buying gun accessories will be checked by the eighteenth generation of the ancestors of the next family, who dares to blatantly buy silencers?

Xu Cangsheng walked in quietly, not disturbing Hao Lao's conversation at all, and after entering the house, he leaned his shoulder against the wall without saying a word.

"Whew. The moment Hao Yong turned around, he saw that there was a figure in the place where no one was there just now, and said in a startled manner: "Team Xu, you floated in, there was no sound at all." ”

Xu Cangsheng's face was not very good: "I asked people to work overtime to do the ballistic test." ”

Hao Lao Crooked and the others immediately concentrated, looking forward to the exact opposite of the imaginary answer.

"As a result, it has been determined by the bullets that were driven into the wall and the bullet casings that fell in the room that the gun that killed the deceased was the same police gun that Zong Hang had lost in the taxi. ”

At that moment, Da Yang's faces and the faces of the others all changed, and everyone knew what these two short sentences represented.

Hao Yong also planned to forcibly explain: "No, Team Xu, I can't even find a single hair at the whole scene, will the murderer leave the bullet casings and warheads for us to check? No, you are joking." ”

Xu Cangsheng suddenly turned his face to look at him, and there was no joke in his serious expression at all.

Hao Lao Crooked seemed to understand that the murderer did this on purpose, he deliberately left clues, just like the first time he killed people with hemp rope, as if saying: "I did it, arrest me!"

"Team Xu, don't use ......"

"No, I don't. ”

What Xiao Liuzi wants to say is 'do you need to take Team Chen over to take a look', after all, this is not anyone's personal matter, the whole case looks like the murderer is provoking the police, if you really can't catch people, not only will the innocent people in Liangcheng die in vain, but the police will also be like a slap in the face...... But Xu Cangsheng didn't let him finish at all, and added: "No matter who it is, no one is allowed to tell Chen Da about this, do you understand?"

After speaking, he didn't wait for Xiao Liuzi to answer, turned his head and shouted: "Da Yang, check the facts of the case, the identity of the deceased." ”

"Xu Ying, 32 years old, LL.M. ......"

Hao Lao glanced at Xiao Liuzi crookedly, Lu Xianzhao shrugged his shoulders, both of them heard it, this time the one who died was another Kochi.
