No trace of espionage

"Fourth, have you noticed that Chen Yifei died behind the door, but there was no blood stain behind the door, or a little blood stain but negligible, but there was a large blood stain on the front of the door. What does this mean?"

When Lin Chuang said this, he felt a little thirsty. He picked up the cup and wanted to drink water, but there was no water.

Seeing this, Liu Ermeng quickly picked up the thermos bottle and continued.

Lin Chuang looked at Mao Yiming: "Captain Mao, you are also a secretary. How come you don't have the vision to refill the water on the peak? I really don't know how you have survived until now."

Mao Yiming lowered his head and said nothing, feeling so angry in his heart, he thought: "Your surname is Lin, you just seized the opportunity and didn't let it go."

Seeing Lin Chuang attacking Mao Yiming, Li Shiqun did not speak, and Wan Lilang even pretended not to hear.

"Explain...the door was open when the murderer committed the crime?" Wan Lilang asked uncertainly.

"Yes, the door is open, and the murderer is the one who killed outside the door. Moreover, I have a bold idea. The murderer killed Tian Chuncai first, and locked the lock when he exited the bedroom. After entering the living room, he killed Hu Yafu first, and finally Kill Chen Yifei from outside the door, then close the door, and leave calmly, without a trace of blood." Lin Chuang said firmly.

As soon as this statement came out, Wan Lilang really admired it, the name of "superior detective" is really well-deserved, everyone can see so many things after walking around the scene, and people like himself are simply pig brains!

And Li Shiqun nodded again and again.

Although the suspicion of Lin Chuang has not weakened in the slightest, but I have to say that this guy's brain is so good that I can't match it.

"Officer Lin, after hearing what you said, the humble job suddenly opened up, and I admire it. Poisoning and killing people from a distance, these two points provide us with two directions for the next step. However, the humble job is still not enough. Please continue to talk about it." Go." Wan Lilang said sincerely.

Lin Chuang was very satisfied with Wanlilang's attitude.

Although he and Li Shiqun were in the same group, he never got involved in their grievances, and just focused on the case. At the same time, he always treated himself very respectfully, without any emotions.

This is in stark contrast to Mao Yiming.

"Director Wan, don't be so polite. Let's discuss it together. I'm just speculating."

"Officer Lin, it is reasonable to speculate that this ability is not small, at least the humble job did not see it."

"The murderer is indeed very cunning. There is no evidence left at the scene. We can only speculate. What we need to do is to find evidence to prove that this speculation is correct or wrong."

"Yes, what Chief Lin said is very true. I think it must be correct. Otherwise, I can't find any other more reasonable explanation."

"Then we just have to wait and see." Lin Chuang said with a smile.

"Commander Lin, is there any more?" Wan Lilang asked.

"There is also the way the murderer entered.

There are two main problems here.

One is how to enter the building, and the other is how to enter Tian Chuncai.

The way of entering the building, my guess is that the murderer went down from the roof of the building to the corridor through the maintenance well, and then poisoned and killed people.

But this speculation also lacks evidence support, because there are no footprints on the roof, nor in the corridor, and at the same time, Tian Chuncai's ladder has not been touched.

Then, there is only one possibility, that is, the murderer has this kind of ladder in his home, and he carried the ladder down from the maintenance shaft, and took the ladder along when he escaped.

As for entering Tian Chuncai's bedroom, he had to find a way to unlock the bedroom door.I saw that kind of lock, and it is a Bangjia brand copper lock made in Switzerland. The biggest advantage of this kind of lock is its high safety performance. It cannot be opened at all with our traditional Chinese lockpicking tools or techniques, only with a key.

However, the key is with Liu San.

Therefore, I think Liu San is most likely to commit the crime.

We can imagine a situation like this: In order to keep his head clear, Liu San declined the invitation of Chen Yifei and Hu Yafu to have dinner together. After nine o'clock, he went upstairs to have a look and found that Chen Yifei and Hu Yafu were already drunk, and then looked at them again. In the case of Tian Chuncai, lock the lock when exiting.

Of course, he could leave it unlocked to facilitate his own crimes, but to prevent him from escaping, Director Wan gave him an order, and he had to do so in front of Chen Yifei and Hu Yafu.

Then, he went back to the first floor.

At two o'clock in the evening, he took out a stick of incense, went upstairs quietly, lit the incense, and blew in the crack of the door.After a certain period of time, he pushed open the door and walked to the bedroom door, also stunned Tian Chuncai who was sleeping.

Then, he took out the key and killed Tian Chuncai with a long-handled murder weapon.

When exiting the bedroom, lock the lock again, and then kill Hu Yafu again across the square.Because Chen Yifei was drunk, he fell asleep on the ground behind the door in his sleep. Liu San went outside the door, followed the same pattern, and killed Chen Yifei.

After doing all this, he had time to throw away the incense and the murder weapon, and then went back to the first floor and pretended to sleep, only waiting for the next morning to pretend to be ignorant and take the initiative to 'discover' that the three had been killed.

Of course, he could just kill Tian Chuncai and let Chen Yifei and Hu Yafu go, if he had a good relationship with them.

However, on the contrary, he just took advantage of this opportunity to kill two subordinates while minimizing the risk of exposure. "

Lin Chuang's idea is very reasonable, and it completely bypasses the difficulty of the murderer entering the murder scene.

Following Lin Chuang's narration, Li Shiqun slowly conceived the scene of Liu San's murder in his mind. Combined with the various doubts raised by Lin Chuang before, he felt that this idea was reasonable, and the suspicion of Liu San's murder was gradually increasing.

"This..." Wan Lilang panicked seeing Li Shiqun's face getting darker and darker.

He trusts Liu San, but this level of trust becomes lower and lower following Lin Chuang's description.

The reason why he panicked was because he was afraid that if Liu San was really the murderer and he was a secret underground party, would he bite him?If that's the case, I won't be able to wash myself off even if I jumped into the Yellow River.

Therefore, he had to try his best to find the flaws in Lin Chuang's words, the purpose was to exonerate Liu San, but also for himself.

"This..., Chief Lin, where is Mixiang? What is the murder weapon? Where was he abandoned?" Wan Lilang asked.

"Director Wan, you should understand that I'm not used to incriminating people without evidence, I prefer solid evidence. Therefore, since Liu San is the most suspected person, let's put him in custody first, and then we will slowly find evidence." Lin Chuang replied.

"Mr. Lin, this matter is not trivial." Wan Lilang said anxiously.

"Director Wan, Liu San is really lucky to have your trust and protection. It can be seen that you are a person who values ​​feelings." Lin Chuang said with a smile.

"Don't dare."

Lin Chuang put away his smile and said seriously: "There is another key point in this case. If Liu San is not the murderer, it will be even more unexplainable."

"Mr. Lin, please clarify..."
