Sima Qiqi still looked at it in disbelief, thinking: "Anyway, Sima Qiqi has no evidence, he didn't admit it to death, and his face can't be eaten as food, why do he care so much, anyway, he bit it to death and said that he stayed up all night last night." ”

The two were in a stalemate, when they heard a familiar voice, and when they looked back, it was Wu Wen, who hurriedly ran over to hug Wu Wen with a smile, hugged Wu Wen and finally breathed a sigh of relief, and quickly wiped the cold sweat oozing from his forehead.

Wu Wen was frightened by his actions, and asked with an embarrassed expression: "Why are you so enthusiastic today, it makes me feel that the hairs on my back stand up." ”

Breathing evenly, he let go of Wu Wen and asked with a smile: "Brother Wu Wen, why did you come to my office so early, ah, is there any patent business that needs to be handled, come and come, go to my office, and talk in detail." ”

At this time, Sima Qiqi stood in front of the two of them, and his smile froze, Wu Wen felt that the atmosphere with Sima Qiqi was a little wrong, but he didn't take it to heart, and said calmly: "Ah, I'm not here for the patent, it's because I thought of something that made the two deceased slowly unconscious, and they haven't been examined by the forensic doctor." ”

When Sima Qiqi heard Wu Wen say this, she invited Wu Wen to her office for a detailed discussion, and she followed curiously. In the office, Wu Wen said excitedly: "I thought of a substance, insulin, that can achieve what Lawyer Sima thought before to make the two deceased slowly lose consciousness. ”

When Sima Qiqi heard Wu Wen say this, he frowned and asked: "Insulin, is it insulin for the treatment of diabetes, this kind of thing will make people slowly lose consciousness, but it can be seen that there are no side effects of using insulin for diabetic patients!" ”

Wu Wenxiang spread his hands and said with a smile: "I think this kind of thing is still explained by you, a biological person." ”

coughed and said slowly: "Insulin, lawyer Sima, you are not wrong, it is used to treat diabetic patients, it is caused by the lack of insulin secretion of diabetic patients, insulin can be produced by our human body itself, its effect is to reduce the sugar in our blood, so that it is maintained in a reasonable range, diabetes is extremely high blood sugar in other words, and if a normal person gets more insulin, then the body will be in a state of low blood sugar." A person's hypoglycemia is described in simple words as fainting from hunger, so hypoglycemia is very dangerous, and a person who drives has low blood sugar, if it is severe, it will indeed make a person unconscious. ”

Wu Wen nodded and said, "Insulin meets all the conditions for causing an accident this time, eh, how about it." ”

Wu Wen laughed, thought for a while and said: "But there is only one way to inject insulin, if you inject it, then you can only inject it at one time, but if you inject less, you can't reach the situation of coma, but if you inject too much, the car should not have an accident when it comes out of the deceased's house." ”

Wu Wen said in surprise: "What, insulin can only be injected, wasn't it reported before that there were pharmacologists who made insulin for export?" ”

Bad laugh

said: "You well-known scientist didn't even find out, it was fake, deliberately creating a gimmick, but there is no benefit for me to say this kind of thing, so I don't care, you don't know, you have been deceived." ”

Sima Qiqi rubbed his temples, sighed and said: "The corpse was burned, so I can't find out if it was injected before death, but listening to what you say, I think insulin should not be what we are looking for, because that substance should slowly accumulate in the body, at first the two deceased did not feel it, and when the accumulation was too much, the two deceased were unconscious almost at the same time, and this will happen." ”

Sima Qiqi said and suddenly thought of it: "Could it be carbon monoxide, I remember that many people slept in the car with the air conditioner on and died accidentally, and carbon monoxide also exists in the atmosphere." Moreover, the vehicle at the scene caught fire at that time, and the fire would also cause an excess of carbon monoxide, so the forensic doctor could not prove when the two deceased inhaled carbon monoxide, and it was possible to die as an accident. ”

nodded and said, "Lawyer Sima, what you said is quite reasonable, but you don't know something, carbon monoxide is the same as ether, it will explode when mixed with air, and there is no sign of explosion on the vehicle at the scene." ”

When Sima Qiqi heard this, he smiled awkwardly and said, "Yes, I thought carbon monoxide was non-flammable like carbon dioxide." ”

When Wu Wen heard Sima Qiqi say this, he said unhappily: "Really, I was angry when I heard carbon dioxide, I applied to the school to use carbon dioxide before, but other teachers applied to leave, so I had to order dry ice online." ”

Hearing Wu Wen say this, he immediately laughed, patted Wu Wen on the shoulder and praised: "Your reaction is quite good, you actually thought of volatilizing dry ice into carbon dioxide, in that case, why are you still so angry?" ”

Wu Wen told that it was because he had applied to the school before, and later bought dry ice by himself, but the explanation was not clear, and the finance side did not report to him.

I was thinking it was funny, and suddenly my expression became serious, and I was talking to myself with my chin in my hand, Wu Wen and Sima Qiqi both stared at it and didn't speak, slapped the table and stood up, Wu Wenwen came to the front, was so frightened that the glasses were scared to fall off, fortunately, Sima Qiqi's office was carpeted, Wu Wen's glasses were not broken, Wu Wen was like a blind man at this time, groping everywhere to find glasses, seeing Wu Wen's blind state, he couldn't help but laugh, picked up the glasses and handed them to Wu Wen, Wu Wen wiped off his glasses and put them back on.

With a complaining face, he said, "You kid will be scared to death if you are so shocked." ”

Sima Qiqi is no stranger to this situation. Calmly asked, "What do you think of?" ”

At this time, he said very proudly: "It's all up to the two of you to say a word, which makes me think that it's not carbon monoxide, it's carbon dioxide, someone put a large volume of carbon dioxide into a container, but this container is not sealed, it will be released slowly, so that the carbon dioxide concentration in the vehicle."

Higher and higher, carbon dioxide poisoning can make a person unconscious, and if the concentration in the body slowly rises, it can even paralyze the central nervous system. It will make the human body uncoordinated, so carbon dioxide is likely to cause this accident. ”

When Wu Wen and Sima Qiqi heard this, Wu Wen nodded again and again and praised: "Yes, yes, yes, your point of view is correct, carbon dioxide does not support combustion, nor will it be arbitrarily mixed with the air to cause an explosion, and there is carbon dioxide in the air, and foam fire extinguishers are also used when fighting fires, so the forensic doctor believes that the cause of death is not suspicious." ”

Sima Qiqi didn't speak for a long time, and then interrupted: "So how can carbon dioxide be obtained, and the car is so big, where will the carbon dioxide be placed without attracting attention?" ”

He waved his hand and said: "Wu Wen also said just now, this carbon dioxide research university can be ordered directly, and although the gas still has safety restrictions, dry ice can be ordered directly online, dry ice is the solid form of carbon dioxide, just like Wu Wen, waiting for dry ice to volatilize." ”

Sima Qiqi continued to ask what was used to hold carbon dioxide gas. At this time, Wu Wen thought for a while and said: "To let carbon dioxide encroach on the air in the vehicle and cause the driver and passengers in the car to coma, at least 70% of the gas must be carbon dioxide, so it does require a large volume container." He waved his hand and said, "You are wrong, you forgot that respiration produces carbon dioxide, so you don't need 70%, because when you exhale more and more carbon dioxide, it can reach the level of coma." ”

At this time, Sima Qiqi looked through the information again, and heard the conversation with Wu Wen, Sima Qiqi's eyes were fixed on the document at this time, and the corners of his mouth rose slightly, and he said calmly: "I think I know something that contains a lot of carbon dioxide, but it won't attract the attention of others." ”

stopped discussing with Wu Wendu and looked at Sima Qiqi.

The two of them heard that Sima Qiqi had found an unobtrusive container containing carbon dioxide.

Before he could ask a question this time, he was asked by Wu Wen first: "Lawyer Sima, you found the container, what is that container, and even the police haven't found it?" ”

Sima Qiqi put the photo file of the scene in front of the two of them, and saw that the wreckage of the car that had been extinguished after the fire had been extinguished in the photo was empty, and Wu Wen did not find anything, turning the pages one by one, but neither of them could find it.

Wu Wenyi shrugged his shoulders and said: "I didn't see anything unusual, in fact, the car is so big, how can there be a container!" ”

knocked on the table and said disdainfully: "Do you mean it or not, you said that it will not attract the attention of others, and you are still looking for something unusual, but to be honest, lawyer Sima, I didn't find anything similar to a container, so don't sell it." Come on, I was fine, but now you're making me itch. ”

Sima Qiqi pointed to one of the photos at the scene of the car accident and asked calmly, "What do you think is this blackened thing in this photo?" ”

Holding his chin and thinking about it, he said slowly: "This is placed in the trunk of the car, it may be some kind of plastic box or other, the rear of my car."

I don't know what's in the box, but it's supposed to be useful for yourself, and it may help you deal with some unexpected situations, and this person may put something different! What's wrong? ”

Don't look over and see that Wu Wen was still thinking, he pushed it and said impatiently: "What are you thinking, how did you wander in space as a great professor." If you don't know, just say it, I won't laugh at you, you have to know that an officer said, 'We thought we knew everything at first, but in the end we didn't know anything', and the big professor didn't know anything about it. ”

At this time, I saw Wu Wen pointing to the things in the photo and asked: "If this is the container you said contains carbon dioxide, it should be relatively large in size, and it has a certain degree of sealing, and such a big thing is placed in the trunk of the car and does not make the mother and daughter suspicious, it should be something that the mother and daughter often see or even their things." ”
