"Okay then......" Cao Ziyan took a deep breath and said as if she had made up her mind: "I'll bring all your clothes back now, I believe in conducting sampling research, and if nothing comes of it in the end, I'm willing to take full responsibility." ”

This move is really a general, if Cao Ziyan really does this, it can indeed prove that this pistol belongs to Ren Xia. At that time, the clothes that Ren Xia used to wipe the pistol were exactly what he was wearing, and Ren Xia didn't expect that there would be residual clothing fibers.

"Are you scared?" Cao Ziyan saw that Ren Xia didn't speak, and said as if victorious: "The police are the smartest hunters, no matter how cunning you are, it is impossible to escape the hunters!"

"What am I afraid of?" Ren Xia took the evidence bag, took out the pistol inside, and threw the evidence bag back to Cao Ziyan: "Now, this pistol has my fingerprints on it, and the clothing fiber is probably wiped off by fingerprints." ”

As we said earlier, the important role of the evidence bag is to prevent the evidence from being contaminated. The term "pollution" here is not a pejorative term, but it means that the initial traces on the evidence no longer exist due to external factors.

Now that Ren Xia is holding this gun in his hand, the clothing fibers may indeed have been wiped off, and Ren Xia's real fingerprints have been replaced by them.

Cao Ziyan didn't expect Ren Xia to make such a move, and she didn't have any precautions at all: "This ......"

"Now take this gun for testing, it does have my fingerprints on it......" Ren Xia smiled slyly: "However, you took the initiative to send the gun over, and I picked it up before I left it, how can you prove that this gun was originally mine?"

"Ren Xia, you're enough!" Cao Ziyan was angry: "Do you believe that I will arrest you now?"

"I don't believe it. Ren Xia hid the gun under the sofa cushion: "You came to me with this gun, in fact, to give it back to me." ”

Cao Ziyan was very surprised: "Why do you say that?"

"The existence of this gun has nothing to do with Zhang Chuantao's killing. Ren Xia's next words were very similar to Kong Fanhui: "Zhang Chuantao is the director of the city bureau after all, and his killing is not the same as an ordinary case, it will cause a huge chain reaction, and a casual little thing in the process of handling the case may lead to unpredictable consequences." In this case, it is better to have one thing to say, that is, find out who killed Zhang Chuantao and directly punish the murderer himself, and don't deal with anything else, this pistol is best to act as if it never appeared. If someone finds out that there is such a pistol left at the scene, it is difficult to say whether it will be used and what it will do. There are so many departments in the police system, and if you don't talk about other departments, let's just say that your criminal investigation detachment, your leader Kong Fanhui, dare to say that he understands every subordinate?"

Cao Ziyan recalled that Kong Fanhui himself had said such a thing, and was speechless: "This ......"

"If there is any mistake in the process of handling this case, it may be used by people within the criminal investigation detachment to get rid of Kong Fanhui. ”

Cao Ziyan didn't understand: "What is the purpose of getting rid of Kong Fanhui?"

"Get rid of Kong Fanhui, and you will have a chance to ascend to the throne......" Ren Xia smiled coldly: "Zhang Chuantao's death means that the pattern of interests will be redistributed, don't you still understand this truth?"

Cao Ziyan suddenly realized: "I see. ”

"How do you make sure that there are no mistakes?" Ren Xia didn't need Cao Ziyan to answer, and gave a direct answer: "It's very simple, more things are better than less things, simplify the case as much as possible in the process of handling the case, and the fewer relevant factors, the easier it is to deal with." If other factors arise and the implication area becomes larger and larger, serious problems may arise, and it is difficult to say whether it will affect Kong Fanhui. For example, this pistol implicated me, so where did I get this pistol, of course someone gave it to me, who gave it to me...... Is there an end to this investigation? In this process, as long as Kong Fanhui is not careful, he will fall into the handle and be accused of being unfavorable in handling the case. ”

"I see. Cao Ziyan immediately made a decision: "You are right, I originally gave it back to you, but you have to remember that I have never been here tonight, and I have not seen this pistol." ”

"Of course. Ren Xia nodded slowly: "Moreover, any problems with this pistol since then have nothing to do with you." ”

Cao Ziyan took back the evidence bag: "That's the truth." ”

"By the way, did you bring your own gun?"

Cao Ziyan was a little vigilant: "Why are you asking that?"

"Because the killer came to the door. ”

Cao Ziyan didn't understand for a while: "What killer?"

"It's the one who shot and killed Zhang Chuantao during the day today. ”

"Sent to the door?" Cao Ziyan still didn't understand: "Which door?"

"Of course it's my door. Ren Xia pointed to the door: "The killer is outside the door now, to be precise, he will walk outside the door immediately, and then knock on the door." ”

Cao Ziyan didn't believe it at all: "How do you know?"

"Wait a minute, someone knocks on the door, you ask who it is, and the outside may answer that the temptation is that it is a food delivery or property staff, and you want to find the owner himself. ”

Cao Ziyan hurriedly asked, "What should I do?"

"Open the door. Ren Xia told Cao Ziyan: "Then you hide on the side of the door, as long as the other party comes in, you will immediately subdue from the rear!"

As soon as Ren Xia's words fell, there was a knock on the door, which made Cao Ziyan startled, feeling that Ren Xia was really amazing, how could he be unpredictable.

Ren Xia glanced at Cao Ziyan and signaled to speak immediately, Cao Ziyan immediately raised her voice and asked, "Who?"

A man's hoarse voice sounded like an accent from outside: "I'm from the property." ”

"What's the matter?"

"May I ask if the director of the industry is here? The other party told Cao Ziyan: "I have a letter of responsibility for arson here, which needs to be signed by every owner. ”

Cao Ziyan subconsciously said, "Wait a minute." Then he looked at Ren Xia in confusion.

Ren Xia said in an inaudible voice, "Hurry up and open the door." ”

"How do you know there's going to be a knock?"

"I'll explain this to you later. Ren Xia told Cao Ziyan: "Anyway, you do what I say, just subdue him." ”

"What if it's wrong?" Cao Ziyan was a little uneasy: "If it's really just a property staff, I'll just put people to the ground like this, isn't it a joke?"

Ren Xia pursed his lips: "Do you make fewer jokes?"

Cao Ziyan was very unhappy: "What are you talking about?"

"There's no mistake about it. Ren Xia told Cao Ziyan: "If you really make a mistake, you will show your ID and say that it is a normal case, and if you accidentally make a mistake, the other party should not be as knowledgeable as you." ”

"What about you?"

"I'm sitting right here. Ren Xia pursed his lips: "Let me appreciate your athletic hands." ”

"Listen to you. Cao Ziyan stood up and came to the door, pulled out her pistol, and then unlocked the door, and immediately stood behind the door.

That is, as soon as the door opened, a man walked in from the outside, dressed like a property officer, holding a stack of documents in his hand, and asked as he walked in: "Is the director here?"

In the next second, Cao Ziyan pounced on her from behind, pressed the opponent's back, pushed her directly to the ground, and then put the pistol against the back of her head: "Don't move! police~!"

The other party raised his hand, scattered the documents on the ground, and asked in a panic: "You...... What do you want to do, I don't have any money, I'm just a part-time worker. ”
