Xilinling's autopsy conclusion proved that Lin Chuang's previous reasoning was completely correct.
Li Shiqun nodded secretly.
He had long admired Lin Chuang's reasoning ability. Otherwise, with his proud personality, he would not have thought of Lin Chuang first when encountering difficult cases.
Wan Lilang took out a paper bag and a new lock from his briefcase and placed it on the coffee table.
Wan Lilang opened the paper package and revealed an old lock. Looking at the ink stains on the keyhole, he 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: "Sir Lin, after investigation, this lock is made in Germany, wss brand. The biggest feature of wss lock is that it is very safe. The lock core is specially made. Unless a key is used, no other lock can be used.
It can’t be opened at all.”
Lin Chuang understood that the "something else" Wan Lilang was talking about was the traditional Chinese lock-picking technique. As long as you master this technique, you can use a piece of iron wire to break the lock.
Those who are good at this technique are those engaged in "dark" work - thieves or agents.
Everyone here, as the best among agents, has received this kind of training.
"I bought the same new lock in my humble post and tried various methods, but it didn't open. Commander Lin, are you interested in giving it a try?" Wan Lilang said.
Lin Chuang can open this kind of lock.
Although this kind of lock seems to be very advanced now, for Lin Chuang, it is still very low. He only needs to give him three minutes, and he will be able to open it.
However, he will not succeed in this ability.
"If Director Wan can't open it, 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 my humble position, but I want to give it a try."
Li Shiqun nodded.
Mao Yiming picked up the new lock and walked aside to tinker with it.
Lin Chuang did not believe that Mao Yiming could open it, and of course he would not wait for the results of his tinkering, so he asked Wan Lilang: "Director Wan, how many keys are there in total for this kind of lock?"
"There are three in total. One is in Liu San's hand, and the other two are in the hands of the house owner. The house owner's name is Jing Zibi, who was once the vice president of Tongde University. He resigned and went to the United States to visit relatives before leaving.
The house was entrusted to the principal and asked him to find someone to take care of it. Because Tian Chun is single and a careful person, he gave the house to Tian Chuncai for temporary residence." Wan Lilang replied.
"Oh, I understand, let me tell you, Tian Chuncai is neither the principal, nor the vice-president, nor a professor, so how can he be qualified to live here? That's it." Lin Chuangdao.
"Yes. Jing Zibi is in the United States. It is impossible for him to cross the ocean and come back to commit suicide. In other words, the only one who can open this lock is Liu San. But, Chief Lin, I really don't want to doubt him because of his humble position."
"There is no need to defend him, Liu San's suspicion has been eliminated." Lin Chuang waved his hand.
"Ah?" Wan Lilang was stunned and thought, what's going on? Why was it ruled out?
Li Shiqun also looked at Lin Chuang with doubtful eyes.
Lin Chuang explained: "First, as you said, Liu Sanru is the murderer. He must have known for a long time that this kind of lock cannot be opened except with a key. Then, he will definitely run away after killing someone.
, will not sit still and wait to die; secondly, the autopsy report shows that Liu San did not lie; thirdly, we have deduced that the murderer must have put poison before killing. This poison should be inhaled and will only make people faint.
It is not fatal. Only in this way can the murderer kill people calmly. This is the fundamental reason why no toxin was found in the stomach contents. If Liu San was the murderer, there would be no need to go to such trouble. He could have put the poison into the food.
, the simplest way is to buy a bottle of sleeping pills, crush the pills and mix them into the food.
However, not only were no toxins found in the stomach contents, but no other drugs were found, nor was there any trace of broken drugs.
Therefore, Liu San is not suspected."
This analytical ability is really strong!
While Wan Lilang was happy for Liu San, he also admired Lin Chuang very much: "Sir Lin, I admire you even though you are humble in your position. I admire you with all my heart."
After saying this, I felt bad again, fearing that Li Shiqun would be unhappy, so I glanced at Li Shiqun guiltily.
Li Shiqun had no expression on his face, but he still nodded slightly and said, "Let Liu San go."
"yes."
Wan Lilang excitedly agreed and went out in person to free Liu San.
Soon, Wan Lilang returned to the living room.
"Has the poison matter been investigated?" Lin Chuang asked.
"I checked. I went to Tongde Hospital to ask. 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, and the shopkeeper said that he had not heard of any traditional Chinese medicine that can be made.
Poisonous gas, unless Jianghu people use incense. He also said that incense is mainly made from datura. It is usually a powder obtained by boiling a lot of datura, then concentrating it, and finally evaporating the water.
And in all the pharmacies I checked, I didn’t find anyone selling Datura." Wan Lilang replied.
"In other words, it's not Mi Xiang?" Li Shiqun said.
"Not necessarily. If he is an old thief, he will definitely have some incense in his hand instead of making it for immediate use." Wan Lilang replied.
When Lin Chuang heard this, he couldn't help but think of Li Honglin.
If he had not known that he had not given the order to assassinate Tian Chuncai, he would have suspected that Li Honglin had done it.
"Now the key is a mystery, and the poison gas has become a mystery. Where is the murder weapon?" Lin Chuang asked Wan Lilang.
"According to your order, I conducted a search within a one-mile radius. All trash cans and corners were found. I only had to dig three feet into the ground and found nothing."
"Haha, that means the murder weapon has become a mystery." Lin Chuang said.
"I 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 witnesses and did not commit crimes. Moreover, these doctors and nurses probably saw Liu San and the others and did not want to
He causes trouble, so no one takes the initiative to contact him unless necessary.
In addition, he saw a total of four patients and wrote four prescriptions. He investigated the four patients separately and found that all four patients had undergone operations and were hospitalized.
Although the operations may be major or minor, these four are temporarily incapacitated and it is impossible for them to leave the ward and commit suicide.
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 suicide."
After Wan Lilang finished speaking, a sad look appeared on his face.
Li Shiqun glanced at Lin Chuang and thought: "So, there is no progress at all. Is this a dead end?"
Lin Chuang also frowned. Although his eyes were fixed on the coffee table, Li Shiqun could see that his eyes were unfocused and he was obviously deep in thought...
