Let you condolences to the task force, have you solved the case?

"It's impossible to knock on the door. The murderer is ready to kill, so it's impossible to knock on the door openly."

"The door lock and windows are intact. Only Secretary Zhou and Professor Tang have the key to this room. Professor Tang's key is not lost, and the murderer can't use the key to unlock it."

"What a strange case!"

Speaking of this, the on-site caravan and the people from the provincial department all frowned, showing a very puzzled look.

Chapter 253 Through Daily Inference

Su Mu heard everyone's discussion and knew that the case had reached a dead end, and they were helpless for the time being.

After pondering for a while, Su Mu suddenly said: "Actually, you can't start with the murderer, but you can start with the deceased, such as whether the deceased has offended someone, etc."

Everyone was startled, and the caravan realized that Su Mu hadn't left, and immediately frowned.

"We've checked this too. Secretary Zhou is usually taciturn, rarely talks to people, let alone has conflicts with people." A person who looked like a team leader from the Provincial Department shook his head.

Su Mu didn't answer immediately, and looked around the room again: "Is there anything missing?"

Several people in the provincial department looked at each other, and then they all looked at the caravan. Obviously they all knew if something was lost, but they couldn't talk nonsense.

The caravan pondered: "I lost something. This thing is very important and has a great impact. Let's put it this way, the lost thing is the reason for the existence of this research institute, and it is even more serious than the death of Secretary Zhou."

"Worse than murder?" Su Mu was also taken aback.

"In this case, the murderer must have planned to kill Secretary Zhou for a long time, so it will be easy to handle." Su Mu laughed.

Everyone looked at Su Mu in astonishment when they heard it, as if looking at a fool.

It's been planned for a long time, but it's easy to handle?Is this true?

Seeing that everyone didn't understand, Su Mu explained: "Since the murderer has planned for a long time, and now we don't know how he killed Secretary Zhou, we can start from the daily life and use some clues from everyone to conclude who the murderer is. !"

When the experts from the Provincial Department heard this, their eyes lit up, and the team leader looked at Su Mu with great interest and asked, "For example, how to start from the daily life?"

Su Mu was standing at the door, and he said to the caravan, "Can I come in?"

The caravan suddenly came over and said hurriedly, "Please come in."

Ever since Su Mu appeared, the caravan's attitude towards him was cold and arrogant, but now they even used the word "please". Obviously, what Su Mu said just now made him feel that this young man might not be simple.

Su Mu smiled and walked in.

"Brother, did you just say that you have a general direction based on daily judgments? You can't ask everyone carefully when they eat, drink, and scatter, or they won't be able to ask clearly until next year." The team leader asked Su Mu.

Su Mu didn't answer right away, he went directly to some physical evidence collected by the crowd, and picked up a sealed plastic bag.

"Huh, you...?" An on-site inspection technician saw that Su Mu touched the physical evidence casually, and immediately prepared to let him put it down.

The leader of the provincial department waved his hand at him, then looked at Su Mu calmly.

"This is a skipping rope. The murderer should use it to blackmail Secretary Zhou." Su Mu looked at the skipping rope, "This can be used to find out where the murderer got the jumping rope from?"

"Rope skipping is too common, the murderer can buy it casually on the street." The technician who was about to drink sumac just now shook his head.

Su Mu put down the skipping rope, and said calmly: "If the murderer was an outsider, he would not buy a skipping rope to kill people. The skipping rope is too long and inconvenient to use. He would choose something more convenient, such as a steel wire."

"So with this murder tool, I'm sure that the murderer is definitely an insider!"

Su Mu glanced at the crowd and revealed the scope of his suspicions.

Everyone in the caravan and the provincial department was shocked. Although they also thought that the murderer might be an insider, but because they checked everyone, there was no doubt, so they had to suspect that an outsider entered the small building to kill someone through some kind of secret method.

Now after hearing Su Mu's analysis, they were sure that the murderer was an insider.

"It's not easy for this young man to judge so much information only through the killing tools. No wonder Fang Haotian asked him to come and help."

The caravan looked at Su Mu and nodded secretly.

"The murderer is an insider. The reason why the murder tool is skipping rope is because even if someone finds out, others will not be surprised." Su Mu said this, looked at the caravan suddenly and asked: "What are the usual methods?" Do you like jumping rope?"

When the caravan heard this, they couldn't help laughing wryly: "Except for our few bodyguards who protect Professor Tang, no one else is needed."

Su Mu nodded and didn't ask any more questions.

When the leader of the provincial department saw it, he suddenly smiled and said, "Why don't you suspect that the caravan is extremely subordinate?"

Su Mu also laughed and said: "They are all very skilled, they can kill with one move without using a rope!"

"Hahaha", everyone laughed after listening, and the tense atmosphere on the scene eased for a while.

Although the team leader asked a joke, and he also knew that the murderer could not be the caravan and others, he still admired Su Mu's accurate judgment ability.

The caravan also smiled at this time, stretched out his hands and said, "We really don't use ropes to kill people."

Su Mu and the others understood what he meant, they only needed to pinch their hands, and Secretary Zhou would not be able to survive.

"Where do you usually keep your skipping rope?" Su Mu asked again.

"It's placed in the activity room at the end of the corridor. There are several skipping ropes in it. I don't know when one was taken away." The caravan shook his head.

"Well, you can ask other people about this to see if someone accidentally broke the murderer's possession of the skipping rope. Once it is confirmed, it will be very suspicious." Su Mu nodded and said.

The people from the provincial department are all old experts. When they heard this, they immediately nodded appreciatively.

In the past, they didn't pay enough attention to skipping rope, they just thought it was used by the murderer casually, but after listening to Su Mu's analysis, they understood that it was the murderer's premeditated killing tool.

Since it is a premeditated murder tool, there is a great reason for investigation.

Su Mu walked to the desk again, and found that the desk was originally attached to the wall, but now one end was dragged away by more than a foot.

He reached out to lift the desk, found it was very heavy, and then put it down again.

"Have you ever touched the desk?" Su Mu turned around and asked everyone present.

Everyone shook their heads, and the team leader of the provincial department looked at Su Mu with more interest at this time: "Does it matter if it has been touched?"

Su Mu nodded, pointing to the imprint left by the desk dragging: "Look here..."

Everyone walked over and saw that the desk had been dragged and left marks more than a foot long on the floor.

"The desk is heavy and leaves marks when it is dragged. It shouldn't be surprising!" said a technician.

Su Mu nodded: "It's not surprising, but look at my traces."

As Su Mu said, he squatted down, and then grabbed the desk and pulled it back hard, there was a harsh friction sound, and the desk left another mark on the floor.

When everyone saw the two connected traces, they couldn't help saying in surprise: "One trace is deep, and the other trace is shallow!"

"Well," Su Mu hummed, "I made the deep marks, while the shallow ones were left by others."

"This shows that the desk was half-lifted and moved, not directly dragged!" A gray-haired expert immediately thought of the result.

"That's right, it's true." Su Mu nodded appreciatively to the old expert.

Chapter 254 Habits in the middle of the night

"Why is this happening?" the caravan asked puzzled.

"It's very simple." Su Mu said with piercing eyes. "This desk was not dragged by the deceased, but the murderer's suspicions, making us think it was dragged by the deceased!"

"This room is specially set up. Even if you drag the desk, you can't hear it from outside." The caravan was still puzzled by the murderer's action.

Su Mu smiled and said: "That's because the desk was too harsh, the murderer was afraid that others would hear it, so he half-raised the desk subconsciously. The reason for this is purely psychological."

When the caravan and others heard this, they suddenly realized.

"I didn't expect you to do research on psychology." The leader of the provincial department looked at Su Mudao with more interest.

At this time, another expert's eyes flickered: "Since this scene was arranged by the murderer, then the scene where Secretary Zhou was killed cannot be in the room, and it is probably somewhere else."

Su Mu nodded: "That's what I infer. The purpose of the murderer is to lead our investigation into a dead end."

Everyone was taken aback, and immediately realized that they had underestimated Su Mu's ability, this young man was too powerful.

Just now, the facts were just as the murderer predicted. The provincial department, the caravan and others were always puzzled by the murder of Secretary Zhou in the room, and couldn't figure out how the murderer got in.

Now according to Su Mu's analysis, the first scene of the murder was not in the room at all. In this way, there is too much information to investigate the case.

In other words, Su Mu successfully brought everyone out of the dead end, allowing everyone to see the hope of solving the case again.

"Awesome!" The provincial team leader couldn't help giving Su Mu a thumbs up, and praised: "Fortunately, the Jiangbin Municipal Bureau let you come here, otherwise we old guys would be ashamed today."

Indeed, if Su Mu hadn't led them out of the dead end, everyone might still be helpless at this time.

"By simply dragging and dragging the imprint, you can judge that this is not the first scene of the crime? It's really amazing!" The caravan also sincerely admired Su Mu.

Su Mu was not complacent about complimenting these big figures, but instead frowned and said: "Now, on the one hand, we need to find clues about the murderer through his daily life, and on the other hand, we need to find the first scene of the crime. Escape!"

Seeing that Su Mu was young, but his demeanor was always calm and calm, everyone looked at him again for a while.

"The first scene?" The caravan pondered for a while and said: "We are stationed on the first floor. If Secretary Zhou was killed downstairs or outside that night, it will definitely not be easy to trick us into transporting the body to the second floor."

Su Mu and several experts from the provincial department looked at each other and nodded. They saw that the caravan and others seemed to have received special training, and it was really impossible for the murderer to transport the corpse under their noses.

Since the caravan had such confidence, it was impossible for Secretary Zhou to be killed downstairs or outside.

"Then there is only one possibility now. Secretary Zhou was killed on the second floor, but not in this room." Su Mu said immediately.

"Where will the first murder scene be?"

"And why did Secretary Zhou go out at [-] o'clock in the middle of the night, and the murderer seized the opportunity to kill him? Was it premeditated by the murderer or was it accidental?"

Everyone frowned, thinking deeply.

Su Mu thought for a moment, then suddenly asked the caravan: "Have any special things happened to everyone recently, or did anyone show a little abnormality towards Secretary Zhou?"

The caravan thought for a while and suddenly said, "Wait a minute."

As he said that, he hurried out the door, Su Mu heard him go to the living room, and asked the seven people to follow him downstairs. After a while, the caravan came up again, holding a thick book in his hand. notebook.

"I called those seven people to the first floor, and they were monitored." The caravan said, and then handed the notebook to Su Mu, and said: "This records the working and living conditions of all scientific researchers. What the professor usually records may be useful to you."

"Professor Tang was greatly stimulated by the murder of Secretary Zhou. I sent someone to take him to a specialized hospital in the morning."

Su Mu nodded, took it over and flipped through it: On April [-]th, Xiao Zhang had an upset stomach and went to the toilet four times in one day; on April [-]th, Secretary Zhou had a headache and took the painkillers prescribed by Dr. It's been a few days...

All the records are similar to these, and the records are very detailed.

Su Mu quickly flipped through it, and saw that the experts from the provincial department also looked over, so he handed the notebook to them.

Several experts immediately got together to watch, especially the recent records, they read very carefully.

But when they finished reading it, they all showed disappointed expressions, obviously they didn't find anything special.

"Did you find anything unusual on it?" Su Mu asked when he saw the disappointed expressions of several people.

Several people were startled, thought for a while, and shook their heads.

"Secretary Zhou has a very severe headache recently." Su Mu pondered.

The leader of the provincial department nodded and said: "I also discovered this, but according to Professor Tang's records, he also had a history of headaches in the past, which seems not surprising."

Su Mu shook his head: "According to the records, as long as the workload is overloaded, Secretary Zhou's headache will be unbearable. Recently, because a scientific researcher surnamed Zhang has diarrhea, Secretary Zhou's workload increased again, which led to headaches."

The caravan next to him immediately said: "That's right. Professor Tang deliberately reduced Secretary Zhou's workload on weekdays. We call him Xiao Zhang. The workload has really increased a lot recently.”

"But is it related to the killing of Secretary Zhou?" Everyone looked at Su Mu puzzled.

Su Mu didn't answer this question: "We know that the murderer killed Secretary Zhou when he left his room at midnight. Just now someone asked why Secretary Zhou went out at twelve o'clock in the middle of the night?"

"This room has a separate bathroom. If you go to the bathroom, you don't need to go out. Therefore, the reason why Secretary Zhou went out is probably because of the unbearable headache, so he went out to get some air."

The leader of the provincial department pondered for a moment, then retorted: "Is your analysis based? Maybe it was just a coincidence that Secretary Zhou went out?"

Su Mu shook his head, stretched out his hand and flipped Professor Tang's heavy notebook quickly, and then stopped on a certain page: "Look, there is a sentence recorded here, he said that Secretary Zhou's headache will be more intense at twelve o'clock in the evening, so he went to the office in the middle of the night The habit of ventilating on the roof.”

Several experts took a closer look, and sure enough, they recorded this sentence in an inconspicuous corner of the notebook, and the handwriting was very scribbled, and it was just a single stroke.

Everyone looked at Su Mu in disbelief for a moment.

"Such a thick notebook, you quickly read it and remember this sentence?" The caravan asked in amazement.

Su Mu didn't answer, but said again: "If the murderer knew about Secretary Zhou's habit, he might use his habit to kill him, and the balcony where Secretary Zhou was ventilating might be the first scene of the murder."

When everyone heard this, they couldn't help but gasp, stared at Su Mu in a daze, and remained silent for a while.

With only a few words recorded in the notebook, the timing of the murder and the first scene of the murder can be deduced. With Su Mu's ability to analyze and deduce, even a few old experts from the provincial department would be ashamed!

Chapter 255 No Trace

When everyone was analyzing the case, there was a sound of footsteps at the top of the stairs, and a subordinate of the caravan came up with two people. The subordinate reported to the caravan: "They are people from the funeral home, and they came to clean up Secretary Zhou's body."
