No trace of espionage

Chapter 1079 The case entered a dead end

The conclusion of Xilinling's autopsy proved that Lin Chuang's previous reasoning was completely correct.

Li Shiqun nodded secretly.

He has long admired Lin Chuang's reasoning ability, otherwise, with his proud personality, it would be impossible for him to think of Lin Chuang first when encountering difficult cases.

Wan Lilang took out a paper bag and a new lock from his briefcase and put it on the coffee table.

Wan Lilang opened the paper bag, revealing an old lock.Looking at the ink stains at the keyhole, I knew it was the lock on Tian Chuncai's bedroom door, and the new lock was exactly the same.

Wan Lilang said to Lin Chuang: "Mr. Lin, this lock has been investigated clearly. It is made in Germany and is of the wss brand. The biggest feature of the wss lock is that it is very safe. The lock cylinder is specially made. Unless a key is used, nothing else It can't be opened at all."

Lin Chuang understood that the "other" mentioned by Wan Lilang was the traditional Chinese lockpicking technique.As long as this technique is mastered, the lock can be opened with a single wire.

Those who are good at this technique are engaged in "shady" jobs - thieves or secret agents.

Everyone here, as the best of the secret agents, has received this kind of training.

"I bought the same new lock and tried various methods, but it still didn't work. Mr. Lin, are you interested in giving it a try?" Wan Lilang asked.

Lin Chuang can open this kind of lock.

Because although this kind of lock seems to be very advanced now, it is still very low for Lin Chuang. He only needs to give him 3 minutes, and he will be able to open it.

However, he won't do this.

"Director Wan can't open it, so I won't do anything, I believe you." Lin Chuang waved his hand.

Wan Lilang looked at Mao Yiming again: "Captain Mao, what about you?"

Mao Yiming was eager to try, and looked at Li Shiqun: "Sir, I don't believe in a humble job, I want to try."

Li Shiqun nodded.

Mao Yiming picked up the new lock and went to the side to tinker with it.

Lin Chuang didn't believe that Mao Yiming could open it, and of course he wouldn't wait for the result of his fiddling, so he asked Wan Lilang: "Director Wan, how many keys are there in this lock?"

"There are three in total. One is in Liu San's hands, and the other two are in the owner's hands. The owner's name is Jing Zibi, who used to be the vice president of Tongde University. He resigned years ago to visit relatives in the United States. The house was entrusted to the principal, and he was asked to find someone to take care of it. Because Tian Chuncai is single and careful, he entrusted the house to Tian Chuncai to live in temporarily." Wan Lilang replied.

"Oh, I see. Let me tell you, Tian Chuncai is neither the principal, nor the vice-principal, nor a professor. How can he be qualified to live here? That's why." Lin Chuang said.

"Yes. Jing Zibi is in the United States. It is impossible for him to come back across the ocean to commit crimes. That is to say, only Liu San can open this lock. But, Mr. Lin, I really don't want to doubt him."

"There is no need to defend him, Liu San's suspicion has been ruled out." Lin Chuang waved his hand.

"Ah?" Wan Lilang was stunned, thinking, what's going on?How can it be ruled out?

Li Shiqun also looked at Lin Chuang with doubts.

Lin Chuang explained: "First, as you said, Liu Sanru is the murderer. He must have known that this kind of lock cannot be opened unless a key is used. Then, he will definitely run away after killing someone. , will not sit still; second, the autopsy report shows that Liu San did not lie; third, we have already deduced that the murderer must have put poison before the murder. This kind of poison should be inhaled, and it will only make people faint It is not fatal. Only in this way can the murderer calmly murder. This is the fundamental reason why no toxin was detected in the stomach contents. If Liu San is the murderer, there is no need to be so troublesome. He can completely pour the poison into the food , the easiest way is to buy a bottle of sleeping pills, crush the pills and mix them into food.

However, not only no toxin was found in the stomach contents, but also no other drugs were found, let alone the slightest trace of crushing the drugs.

Therefore, Liu San is not suspected. "

This analytical ability is really too strong!

While Wan Lilang was happy for Liu San, he also admired Lin Chuang very much: "Mr. Lin, I admire you for my humble job, and I admire you with all my heart."

After saying this, he felt bad again, afraid that Li Shiqun would be unhappy, so he glanced at Li Shiqun with a guilty conscience.

Li Shiqun was expressionless, but still nodded slightly, and said, "Let Liu San go."

"Yes."

Wan Lilang agreed excitedly, and went out in person to release Liu San.

Soon, Wanlilang returned to the living room.

"Have you investigated the poison?" Lin Chuang asked.

"I checked. I went to Tongde Hospital and asked. The doctor said that there is no western medicine that can volatilize or form poisonous gas after burning. I went to a nearby Chinese medicine shop to investigate. The shopkeeper said that I have never heard of any traditional Chinese medicine that can be made. Poisonous gas, except for the incense used by Jianghu people. He also said that the incense is mainly made of Datura as raw material, and it is usually a powder obtained by decocting a lot of Datura, then concentrating, and finally evaporating the water. But in all the pharmacies I checked, I didn't find any mandala sold." Wan Lilang replied.

"That is to say, it's not Mixiang?" Li Shiqun said.

"Not necessarily, if you are an old thief, you will definitely have the incense in your hand, and you will not make it and use it now." Wan Lilang replied.

When Lin Chuang heard this, he couldn't help but think of Li Honglin.

If he hadn't known that he hadn't given the order to assassinate Tian Chuncai, he would have suspected that Li Honglin did it.

"Now the key is a mystery, and the poisonous gas is also a mystery. What about the murder weapon?" Lin Chuang asked Wan Lilang.

"According to your order, I searched within a radius of one mile. All the trash cans and corners were searched, but I was only three feet away from digging the ground, but I didn't find it."

"Hehe, in other words, the murder weapon has become a mystery." Lin Chuang said.

"The humble staff also investigated the people who had contact with Tian Chuncai yesterday. He was in the hospital all day yesterday, and all the doctors and nurses who had contact with him had testimonies that they did not commit crimes. Moreover, these doctors and nurses probably saw Liu San and the others and did not want to mess with them. Trouble, so, unless necessary, no one took the initiative to contact him.

In addition, he saw a total of four patients and prescribed four prescriptions. He investigated the four patients separately and found that all four patients had undergone surgery and were hospitalized.

Although the operations were large and small, these four were temporarily incapacitated, and it was impossible to leave the ward to kill people.

In addition, the family members of these four patients have never left the patients and have been staying with them in the hospital, so there is no possibility of committing a crime. "

After Wan Lilang finished speaking, a sad look appeared on his face.

Li Shiqun glanced at Lin Chuang, and thought: "So, the case has not made any progress. Is this a dead end?"

Lin Chuang also frowned. Although his eyes were fixed on the coffee table, Li Shiqun could tell that his eyes were not focused, and he was obviously lost in thought...

　I wish all book friends a happy Mid-Autumn Festival!
