Zuo Luo began to think in his heart that the bodyguard supervisor was the murderer and cooperated with the mobile bodyguard. The mobile bodyguard quietly went upstairs after breakfast and slashed the stairs bodyguard. Then... seven meters away. That could only be the mobile bodyguard and the door bodyguard. The mobile bodyguard could cooperate with the door bodyguard. The mobile bodyguard could see the bodyguard being attacked during the monitoring of the bodyguard.

Su Cheng said arrogantly: "I would like to give you a reminder, don't be fooled by the illusion of a bodyguard at the door. The bodyguard's phone at the door was dropped. The phone he answered was an electric shock device. If you carefully compare the three electric shock positions, you can find that the area of ​​the bodyguard at the door was electrocuted by a larger area."

Song Kai said: "Consultant, you mean that the bodyguard guarding the door of the bedroom door does not need to be calculated, he can be corona at any time."

"Yes, maybe it was his own corona himself." Su Cheng said: "Mobile bodyguards go upstairs, Corona Stair Bodyguards... I must admit that what Zuo Luo said makes sense. The number of murderers in this case is uncertain, and maybe four people may join forces to commit the crime. We should pay attention to a key point. The mobile bodyguards are the person responsible for taking away the bodyguards at the Corona door, as well as the bodyguards' electric shock device of the bodyguards and the bodyguards' electric shock device. After he warned, the bodyguards arrived one after another. At this time, he could easily hand over the electric shock device and the electric shock phone to other people who responded. After all, the boss behind the scenes...haha."

Su Cheng said: "Lu Renyi, we can't encounter cases related to certain people, right?"

"He Gang is not Mrs. Hua, why can't you touch it?" Lu Renyi said: "Start solve the case and I'll pour water for everyone."

Su Cheng watched Lu Renyi enter the Kaishui Room and said, "There are at least two murderers in this case, one of which must be a mobile bodyguard. I currently prefer the bodyguard supervisor because he arranged for the mobile bodyguard to go for breakfast first. But... they all asked the mobile bodyguard to go for breakfast first. However, in terms of the case, the bodyguard supervisor and the mobile bodyguard can perfectly commit the crime."

"Consultant, this may not be true." Fang Ling said: "According to my investigation, there is a deep personal conflict between the mobile bodyguard and the bodyguard supervisor. The bodyguard manager arranged mobile bodyguards to enter this group to restrain each other. Anyone who has malfeasance will be reported. A team cannot be perfect and harmonious. Managers need to use the conflicts between them to balance the relationship."

Fang Ling added: "Of course, due to the boss behind the scenes, they may also join forces." Hua Liang is likely to be the leader of the hanged ghost. If you want to do bad things, the people below will naturally help. He Gang's influence is an objective factor.

While everyone was pondering, Lu Renyi filled everyone with water and sat quietly aside.

After a long time, Zuo Luo asked: "Is the clothes of the mobile bodyguard evidence?"

Fang Ling asked and replied: "Yes, according to his confession, he found that the bodyguard was in a coma after going upstairs. Then he called the bodyguard supervisor on the same channel intercom and ran to the bedroom. He saw the bodyguard at the door unconscious and the bedroom was invisible. He entered the crime scene in the bedroom. Without the channel responded, he turned to the bodyguard main channel to issue a warning." The main channel and the regional channel were separated. If they were not separated, the main channel would be in chaos. Because the bodyguard supervisor would name his team members every ten minutes or even shorter, and the team members had to answer.

Fang Ling: "So his coat, trousers and shirts were collected."

Zuo Luo said: "The heat generated by electric shocks is likely to cause changes in nylon in the pocket."

Song Kai replied: "I have checked my pockets and there is no change due to heat."

Zuo Luo said: "Check dna?"

"The suit pocket has not been inspected yet." Song Kai said: "Boss, this is a blessing." It is possible that the security guards' DNA will be left.

"Maybe we will be lucky?" Zuo Luo looked at Su Cheng who was smiling: "What are you laughing at?"

"A hundred steps and fifty steps to laugh." Su Cheng said: "I don't think it's necessary to have someone else."

Damn, here we come again... By the way, the previous topic has not been finished yet... Forget it, I am not in the mood to argue. Zuo Luo later understood the meaning of laughing for 100 steps. It was not that both of them were stupid, but that Zuo Luo only thought about fifty steps, and Su Cheng thought about one hundred steps, so Su Cheng was laughing for 100 steps Zuo Luo for 100 steps. This laugh was a ridicule.

...

A day passed in a busy and waiting period. Zuo Luo and Su Cheng seemed to have worked. After get off work, Zuo Luo started the car and lit a cigarette leisurely outside the car door. Su Cheng was slowing out and got in naturally. Zuo Luo drove back to the Wulian community. When he got home, Zuo Luo went to take a shower, and Su Cheng called the takeaway. Then Su Cheng went to takeaway, Zuo Luo picked up the takeaway and got a food basin. The two watched the news, watched TV, and ate takeaway. After the end, Zuo Luo cleaned up, Su Cheng made black tea, and then watched the local evening news and rested.

It's normal? What's abnormal is that there is no dialogue between the two.

At around 10 o'clock the next morning, the two of them were waiting in the physical evidence team of the police station. As soon as the report came out, Zuo Luo called: "Bai Xue, take someone to bring the mobile bodyguard and the bodyguard at the door to the police station. I will send you an electronic detention notice later."

Su Cheng called: "Fang Ling, if you bring someone to arrest the bodyguard supervisor, someone will send you a criminal detention notice."

Zuo Luo looked at Su Cheng with a squinted look: "Is it interesting?"

"Yes, it's very interesting."

...

In the end, only the bodyguard supervisor and the mobile bodyguard were brought.

Su Cheng didn't say why he arrested the bodyguard supervisor. Zuo Luo had no choice but to be Fang Ling and Song Kai accompanied Su Cheng for interrogation.

Fang Lingxian formulated the importance of the bodyguard supervisor, and then Su Cheng did not wait for the bodyguard supervisor to complain and said, "We will fight quickly because your methods are too clumsy, and I really don't want to waste too much time... The first evidence is that your dna is in the pocket of the mobile bodyguard."

Bodyguard Supervisor: "I..."

Su Cheng interrupted: "You commit crimes with the mobile bodyguard. The mobile bodyguard went downstairs to have breakfast. You call the bodyguard at the door, and the bodyguard at the door was electrocuted by the phone. At the same time, the mobile bodyguard came back from dining and went up the corona stairs bodyguard. You ran to He Gang's bedroom and killed He Gang, you handed the electric phone to the mobile bodyguard. The mobile bodyguard and you entered the study to shock you. Then you warn. When the time is in place, twenty seconds is enough."

Su Cheng said: "You wore rubber gloves to commit crimes. After committing the crime, the mobile bodyguard used gloves to reverse the electric shock phone and shock device and put it in the pocket. Why? Because you know that electric shock phone and shock device will generate a lot of heat and may damage the material of the pocket. When you wear gloves, you leave DNA, or to be precise, two hairs are left in the gloves. The mobile bodyguard's anti-suspension electric shock device is equivalent to placing your DNA in your own pocket."

Su Cheng: "You dropped the phone number of the bodyguard at the door earlier. Before entering the bedroom, you switched the real phone and the electric shock phone... I guessed that it was a bit strange. What was the mobile bodyguard doing during your murder? I thought it was you who cleared the surveillance information, but when you thought it was wrong, you cleared the surveillance information and turned off the surveillance phone. It would be difficult for the mobile bodyguard to cooperate with you in time. This case requires the cooperation of the mobile bodyguard and you very much. So you cannot turn off the surveillance.

The bodyguard appears on the stairs, and you immediately call the electric shock phone. When the bodyguard at the door answers the phone: When feeding, the bodyguard at the stairs will naturally look at the bodyguard at the door. At this time, the bodyguard at the stairs will attack the bodyguard at the stairs, and the bodyguard at the door is electric shocked. You go to the bedroom to kill people, the bodyguard will clear the information and turn off the surveillance. The two of you are done, you go back to the monitoring room, the bodyguard will take the electric shock phone with gloves and counter-condoms, and then put you in the corona, put the electric shock device into the gloves and put it in your pocket."

Su Cheng said: "Don't worry, I know you want to ask about evidence? The first evidence, how can your hair fall into the pocket of the mobile bodyguard? The second evidence, from the current photos, you can tell that the person who shocked you and the electric stairs bodyguard are left-handed, you are right-handed, your mouse is on the right, and the mobile bodyguard turns off the surveillance, and habitually pulls the mouse to the left, keeping the mouse on the left. The physical evidence group simulated the scene and believed that when the mobile bodyguard turns off the surveillance, you cannot sit on the computer chair in front of the screen."

Su Cheng said: "With these evidences, it is basically possible to conclude that the mobile bodyguards are involved in the crime. Do you think he will betray you? I know that you two have personal conflicts, but they cooperate because of the common task. Once the task is completed, will he drag you into the water? "

Su Cheng stopped the bodyguard supervisor again and said, "Would you say it later? Let's talk about your problem now. Suppose you are sitting in a chair and looking at the screen, you can find that the mobile bodyguard attacked the stairs bodyguard. Unless you are not sitting in a chair. But in the crime scene, you did faint on the chair, in front of the screen. Your confession said that you have been staring at the screen... You have a low-level mistake in this case. The intercom you used before called the analog intercom. When he took He Gang's job, because the analog intercom was easily eavesdropped, he used the digital intercom. There was no big difference in function, use, or even appearance. The main difference is that the digital intercom is more reliable than the analog intercom. At the same time, the digital intercom has a data backend, and can even locate your movement trajectory."

Song Kai looked at Su Cheng and said that, yes, the data backstage and positioning the movement trajectory of Su Cheng were correct. But the problem is that the movement trajectory is not so accurate and cannot be reflected by moving about ten meters. As for the data backstage, the bodyguard supervisor did not use the walkie-talkie when committing the crime, so naturally there was no recording.

Su Cheng is the next small bet. When he gets a digital walkie-talkie, someone will definitely make a difference. However, after using it, people who use analog walkie-talkie for many years may ignore the function of recording the movement trajectory of the digital walkie-talkie. At this time, Su Cheng reminds the bodyguard supervisor that the digital walkie-talkie has this function, which means that the trajectory of the murder he carried with the intercom equipment was recorded. In fact, there is no such accurate trajectory record. If the bodyguard supervisor only knows the first half, then he will collapse. Assuming that he understands everything, it doesn’t matter. As mentioned before, the mobile bodyguard cannot escape.

Of course, you can also examine the mobile bodyguard first and then the bodyguard supervisor, but in this way, Su Cheng has to do two jobs, so Su Cheng chose to do one job.

"What? I dare not take it as a lie?" Su Cheng saw the bodyguard supervisor panic expression and knew that he had bet right. He asked a question and added: "If you can't escape, I will examine you first. I don't want you to lie. I hope you can keep some dignity. Okay, I've said everything I should say, and now you've said it."

The bodyguard supervisor vented his anger: "That's right, I killed He Gang."

The crime process was exactly the same as Su Cheng said. The bodyguard supervisor and the mobile bodyguard cooperated with each other in a wonderful time. They knew that the police would definitely put them on the list of suspects, but as long as the police could not determine who committed the crime, they could not be convicted. The bodyguard supervisor knew that it was troublesome because the mobile bodyguard was basically killed. The mobile bodyguard had a personal grudge with him and could not let him go. Then Su Cheng explained the details of the scene. The bodyguard supervisor found that even if the mobile bodyguard did not betray him, he could not make a lie. The movement trajectory of the digital intercom completely made him give up hope. He thought he had made a big mistake. He remembered the function of recording the movement trajectory mentioned when introducing the digital intercom. However, he was used to using simulated intercom and ignored this function. However, he did not expect that the reason was that the movement trajectory was indeed there, but small-scale movement could not be accurately positioned.

There is also Su Cheng's attitude. Su Cheng did not examine the mobile bodyguard first and did not allow the bodyguard supervisor to interfere. A posture of winning was assured that the bodyguard supervisor was trying to resist. Su Cheng understood his surname and knew that the bodyguard supervisor was a person who likes face. Finally, he induced him to keep some dignity.

Su Cheng has clear consideration in this case. Assuming interrogation of the mobile bodyguard first may lead to a silent confrontation of the bodyguard supervisor. This is a kind of interpersonal relationship psychology. The mobile bodyguard and the bodyguard supervisor have personal grudges. The bodyguard supervisor would rather sell the mobile bodyguard himself than sell himself. If the mobile bodyguard sells the bodyguard and goes out of seclusion, the bodyguard supervisor may choose to remain silent.

All of this increases the chance of interrogation results, which does not mean that it is inevitable. This time, Su Cheng was confident that when interrogating the mobile bodyguard, he asked the mobile bodyguard to sell the bodyguard supervisor. Conspiring to commit crimes is like opening a shop in partnership. It seems that both parties have cooperation and tacit understanding, but when there is a crisis, both parties will have distrust of the other party, and at the same time, they will reduce the other party's contribution in their hearts and increase the negative impact.
