Su Cheng asked again: "We? There is a big difference between us and me. When we talk about me, we say it with confidence. When we talk about us, we are guilty. My biggest mistake is to ignore whether you are a surgeon or a relatively good surgeon. I was thinking that a surgeon can kill, lurk, sneak attack, and kill with one knife, but why should he use a bone-cutting knife? Could it be that the surgeon uses a bone-cutting knife to perform surgery on the patient?"

Su Cheng said: "It is absolutely impossible. Surgeons are best at scalpels. Surgeons are determined to plan to kill people and must carry a knife. How can they get a bone-removing knife? This is a little ridiculous."

Su Cheng said: "I am very willful. I think the weapon is a scalpel, not a bone-cutting knife. Why do you suspect you? Only neighbors can get into the neighbor group and investigate all neighbors. Only you have the ability to kill one blow, and others are not sure whether the heart is in the middle or on the left. That question is, since it is the person killed by a scalpel, how can the bone-cutting knife have blood? How can it become a weapon?"

Su Cheng said: "I went to get a haircut last month and received me as a novice. He accidentally cut my hair a little too short. He quickly made an excuse and asked the master to help him with the aftermath. The hair is too long, the master can cut it short. What should I do? Can I connect it? No, that is impossible. The master is very experienced, so he used my short hair as a reference to cut all my hair short. When I looked at it, I really couldn't tell that it had been cut."

Su Cheng: "Let's get straight to the point. You lurk in Zhang San's bedroom, but I didn't expect that Zhang San was not alone. What should I do? When Zhang San entered the bedroom, he would sooner or later find you. You had no way out, so he assassinated Zhang San with a scalpel as planned. Next, you have a few minutes to think. Then, Hua Feiyu was frightened. We calculated that Hua Feiyu went out to the neighbors to see the living room. It took seventeen seconds during this period. We practiced on the spot. It didn't take so long, it only took ten seconds."

"When Hua Feiyu went out, you immediately went to the kitchen, took the bone-clearing knife to the bedroom, inserted the knife into the wound where the scalpel was opened, then pulled out the knife, put the knife back into the kitchen, avoiding the side, and waiting for the neighbors to pay attention to the bedroom, you took the opportunity to mix in." Su Cheng said: "You have successfully created a murder scene in the secret room."

Su Cheng told Li Si not to speak: "I know you want evidence... it's quite difficult. The bone-cutting knife is longer and wider than the scalpel. You are skillful in the technique. You stabbed it in according to the edge of the knife and completely destroyed the wound. The forensic doctor told us that it is difficult to prove that the murder weapon is a scalpel. And you have relevant knowledge. You have bleaching water at home, which can destroy DNA. Clothes, weapons, and everything is washed clean by you. As a fan of premeditation and detective novels, you have prepared head covers, gloves, shoe covers, which are basic supplies in the operating room. There are no fingerprints, no hair, and no shoe prints... Then when did you take off these things?"

Su Cheng: "It must be that Hua Feiyu was scared and he had to start preparing before he was scared, because you don't know how much time you will have next. You must take off some things first. After Hua Feiyu was scared, you go to the kitchen to decorate the crime scene."

Li Si was shocked.

Su Cheng smiled: "I think you guessed that you didn't know when Hua Feiyu knocked on the door and when he came in, so he took off his hair cover first and hid behind the door. At this time, the windows in the room were closed, and the room was still a little stuffy in December, and you leaned against the wall. Fortunately, there was no hair on the scene. Unfortunately, your dandruff and sweat stuck some on the white and gray wall. You are a doctor, and you should know that your hair may not be able to detect DNA, but dandruff can be detected. This is the report of the physical evidence group to extract fingerprints from you as a witness to enter the scene, and DNA was used to identify the murderer's fingerprints and DNA. After the efforts of the physical evidence group, it was confirmed that the dandruff DNA was exactly the same as your DNA."

Li Si Hao replied after a while: "Okay, I admit that I have entered Zhang San's bedroom and sneaked in, but it was not the time of the incident."

"oh?"

Li Si said indignantly: "Zhang San, that bastard, attacked my wife and took nude photos. Although two months later, although the background was dealt with, my wife was a serious person. She clearly remembered that during the day, the toilet was blocked and she went out to find a telephone number for the ducts on the stairs. After asking, Zhang San said he could do it. Unexpectedly, this beast came to my house to clear the toilet, dared to drug my wife, and took photos. I sneaked into Zhang San's house to check this matter and get the U disk with my wife's photos."

"We have mastered the motive for killing, but it's good to say it again. Your excuse is pretty good. You are going to steal back to the U disk before sneaking into the Zhangsan family, right?"

"right."

"Then why can't you find your fingerprints everywhere?"

"Because I know stealing is illegal, I wear headbands, foot covers and shoe covers."

Su Cheng said: "Zhang San's bedroom has no table, only a wardrobe with two drawers. As a deliberate thief, I would like to ask if the two drawers in the wardrobe are locked?"

Li Si was stunned: "It seems that there is no."

“What’s inside?”

Li Si suddenly came back to his senses: "I don't need to answer this question. You have to prove that I am guilty, not that I prove that I am innocent."

"This statement is OK for the police, but not for the judge. This is the motive for the crime. The judge will ask you to answer. How do you answer?" Su Cheng said: "There is another point, did you sneak into the Zhang San family on the day of the incident?"

Li Si thought wildly, and after a long time, he nodded: "It's past four o'clock, I'll get off work at three at half past three, get home at four o'clock and go directly to Zhangsan's house and leave around four at twenty."

"Are you sure?"

Li Si covered his mouth and rubbed it back and forth, thinking...

Su Cheng said: "You have no way out. Zhang San was feeling uncomfortable the day before the incident and stayed at home for a day. Compared with the time you went to work and Zhang San was at home, in these seven days, you only have time on the day of the incident. You only have time after four o'clock, and Hua Feiyu entered the door at 4:40."

Li Si replied: "I left at 4:20, I'm sure."

Su Cheng asked: "On the day of the incident?"

"Yes, on the day of the incident."

Su Cheng said: "Do you know? Hua Feiyu arrived at Zhang San's door at 4:00 and waited for Zhang San to go home."

Li Si hurriedly said, "I remembered it wrongly, it should be from 3:55 to 4:50."

Su Cheng was too lazy to pay attention to him, so he snapped his fingers and Zuo Luo released a photo: "You are entering your own building at four o'clock. This is a photo taken by outdoor surveillance. Before going upstairs and entering Zhang San's house, you have to wear gloves first and use the key to open the door. After entering, you have to put on a head cover and shoe cover. You also have to search for things. Do you think the judge will think five minutes are enough?"

Su Cheng added: "If you want to make a fuss about time, save money. We have passed the surveillance time. We have even had surveillance security testimony in the past month. No one has debugged the surveillance time. Hua Feiyu's mobile phone and watch are all right. The worst thing is that it is not that you get off work alone at 4 o'clock. A neighbor came home at 4 o'clock and saw Hua Feiyu talking to each other for a few words. You can argue again. In the past two days, our seven groups have sorted out all the information that can be sorted out. We even already know that Zhang San went home at 4 o'clock. It was the time you used deception to control, and it was also the reason why Zhang San rushed back to see Hua Feiyu, because Zhang San was deceived by you... Come on, what else? Just let the horse come over."

Speaking of this, Li Si finally sighed helplessly...

The motive was as Li Si said. Li Si's wife confronted Zhang San, but Zhang San refused to admit it. The police came to investigate, but it took too long and there was no evidence.

The crime process was mostly the same as Su Cheng said. Li Si was very nervous at the time and had thought about using a bone-cutting knife to cover the scalpel. It was impossible to use a scalpel, because the first person to doubt it was him. He paid great attention to details and avoided blood splashing on himself. All gloves and other crime items were disinfected and destroyed with bleach, leaving no hard evidence. The only reason was that the head hood was too urgent, and Zhang San regretted that he should go to the kitchen before taking off the head hood.

He never thought that taking off the headband was the right way to gain time without knowing the length of time. But he regretted it when he failed.

Su Cheng: "Everyone who premeditates a crime thinks carefully and clearly, but it is not that simple when committing a crime on the spot. It is really difficult to check if you are lucky. You are not lucky and have many flaws. You may not know that, such as this kind of premeditated crime, it is relatively easy for the police to find the suspect, and premeditated crime is mostly acquaintances. And you and your wife once went to the police station for this matter. There are relevant records. It is only a matter of time to find you. The most difficult thing in premeditated murder is to hand over..."

Zuo Luo slapped Su Cheng's mouth, damn it, and said nonsense.

Su Cheng smiled, stood up and nodded to the special police. The special police stepped forward and asked Li Si to follow them.

The door closed and the video was closed. Su Cheng said: "Exchange murder is also a misunderstanding of the police. Premeditated murder is probably related to acquaintances, but the suspect has nothing to do with acquaintances, and there is no scene of passionate murder..."

"Okay, I'll treat you better in the future, can you stop killing me?" Zuo Luo said: "Zhou Duan, what do you think?"

Su Cheng said: "I plan to ask Zhou Duan directly."

"Just kidding?" Zuo Luo said: "We can only investigate this case secretly."

"No, my standard for filing this case is to treat the Ma Bureau as the suspect, the only target, the only suspect. I must figure out why Zhou Duan was involved. The best way is to ask Zhou Duan. If Zhou Duan is a bad person, I won't investigate."

Zuo Luo said seriously: "I don't agree. I think we need to start a comprehensive investigation of Zhou Duan. It's too stupid to showdown now."

Su Cheng said: "I want to bet this, and I think I have a high chance of winning."

"If it's a bad guy in the week, are we going to alert the enemy?"

"You have to believe that most fat people are not bad people." For example, Xiami!

"Damn."

“Anti-trough.”

"You are not allowed to do anything until I agree."

"You won't agree to my bet-like solving."

Zuo Luo stabilized his emotions and said, "You are more rational. Shangguan Wubing, whom I dug up recently, is also related to Zhou Duan. Can't this deepen the suspicion of Zhou Duan?"

Su Cheng said: "Zuo Luo, let me tell you the truth. If the opponent is Zhou Duan, even if I am alarmed, I will be able to turn the tide. If the opponent is Ma Zhidao, I have no confidence at all. What is Zhou Duan's ability? What is Ma Zhidao's ability? You should know best. Zhou Duan only has one ability, and his keen eyes can recognize the beads. His inference ability, criminal investigation ability, and fighting ability are all average. Can this reason convince you?"

Zuo Luo thought for a while and replied: "No...but if you persist, try it first."

"The dead duck is stubborn."

"I don't bother with you."

Su Cheng is not afraid that Zhou Duan is a bad guy, because Su Cheng believes that Zhou Duan is not an opponent and is not afraid of it. Zuo Luo usually does not accept this logic, but it makes sense to not deny it. Su Cheng insists so much, and Zuo Luo finally makes concessions.

...

Zhou Duan is a stranger among the criminal police, especially the field department in Z department. Zhou Duan usually goes to and from get off work from 9 to 5 most of the time. The specific work is handled by six deputy captains in a group. Zhou Duan’s job is to assign the case to six groups, and then make tea and other results.

It sounds shameless, but four of the six deputy captains here were selected and promoted by Zhou Duan, and the other two were also talents in the unit promoted by Zhou Duan Huiyan. Zhou Duan's criminal investigation business is loose. If there are no cases involving departments or major cases that the director is in charge, Zhou Duan is very punctual when commuting to get off work.

Everyone joked that the internal staff did not go to get off work so on time, and it was even more excessive that he was the field staff, and he could not come to work openly, be late or leave early. Many people have opinions on this, but they did not include a group of people. Can they promote six independent deputys?

Employing people is a big deal. Some people like loyal people, regardless of their ability. Some people like mediocre people to protect their status. According to the current trends and trends, taking Journey to the West as an example, Sun Wukong, his boss loves and hates him, and he also makes achievements. Such people must be used, but they have to wear a tight curse. Zhu Bajie's representative white-collar class has flattery and some abilities, but he does not have the best of his achievements. He always stands with his boss. His boss opposes Sun Wukong, and he supports him. The worst thing is Sha Monk, who works hard and hard, but has poor abilities, is not good at socializing, and does not look at his face. Although such people have virtues, they catch every step on the market.

Zhou Duan used six Sun Wukongs. First of all, he had to identify Sun Wukong and then give them rights. At the same time, he had to restrict and regulate them, only do things and not make trouble. Zhou Duan did a pretty good job last year.

Zhou Duan got off work with peace of mind today. Zhou Duan drove away and drove halfway. The car behind him made a double flash. Zhou Duan realized that he was being followed. Although he had been honed in the criminal police team before, he had basically lost all his skills after becoming a manager. Zhou Duan looked at the rearview mirror and knew it was Zuo Luo's car, so he slowed down. Zuo Luo overtook and led the way in front. The two cars turned east and west. He arrived near the Nan District Government, then took another half a mile, got off the highway, and drove to the second floor parking lot of a commercial square.

This commercial square is average business, with enough parking on the first floor of the underground floor now. There are only two cars on the second floor, and ghosts can't be seen even when you look around. There is an advantage in talking to this place, which is clear at a glance and is difficult for others to get close to.

The three got out of the car, Zuo Luo first pointed the cigarette to Zhou Jue, and Zhou Jue spitted out the smoke ring and asked, "What's the situation?"
