It seemed that they were all dozing off, and they woke up and asked: "What's the matter, Brother Wu Wen, do you know that you can go to treat insomnia, who doesn't know that the mother is a woman, the car is the deceased, and the things in the trunk are of course theirs." But you're right, so it seems that the murderer should be very familiar with them, so he can replace one thing without being discovered, then there are only two suspects, one is Chen Gong, and the other is the client's woman surnamed Gan, that is, Chen Gong's sister-in-law. ”

After speaking confidently, he smiled triumphantly and made a triumphant gesture to the two.

Wu Wen pressed down his raised hand and asked patiently: "Why do you still suspect the client who is looking for you, if the client kills someone and comes to you, and you find out, then is that client stupid or smart?" ”

At this time, he was very confident, and told Wu Wen that they had cooperated together in several cases before, including the murderer who reported the case, and also cleared the charge of the scapegoat, which was completely acting, if it weren't for Lawyer Sima's eyes, he would have inherited a large amount of inheritance a long time ago. Normal people think that murderers should have their eyes flashing and try to avoid contact with police and lawyers, but some smart murderers just do the opposite, think backwards, and sometimes can't rely on common sense to infer it.

Wu Wen was speechless, and Wu Wen, who was already stunned at this time, nodded slowly in agreement.

At this time, Sima Qiqi interrupted: "No, you are wrong this time, Chen Gong's sister-in-law is absolutely not suspicious." ”

Looking at Sima Qiqi suspiciously, reminding Sima Qiqi not to forget the previous case of Tie Yiming, Sima Qiqi shook his head and said: "This case is not so complicated, you must know that the police, including the forensic doctor, believe that the cause of death of the two deceased is not suspicious, and it has been prepared to close the case as an accident. ”

After thinking about it, he said: "Then it may be like the Yan family, for the sake of the inheritance, all the doubts are led to Chen Gong, Chen Gong is imprisoned, and this sister-in-law can inherit the inheritance as the guardian of Chen Gong's youngest daughter." Well, it's definitely right to think so, I'm not wrong, Lawyer Sima, Lao Wu learn, look at my wisdom buddy, use your brains more, don't die reading, ahahaha! ”

Sima Qiqi knocked on the table, interrupted the laughter, and said slowly: "I still prefer the man named Chen Gong." Judging from the client's performance, she didn't think about the problem so rationally, but the man named Chen Gong was too rational, and it was possible for such a person to design such a sophisticated murder plan. ”

At this time, Wu Wen suddenly interrupted: "Then don't argue with the two of you, Lawyer Sima, can you tell me what exactly you found to contain carbon dioxide gas?" ”

Sima Qiqi was disturbed and almost forgot about business, apologized to Wu Wen, rolled his eyes, and said slowly: "It's a fitness ball." ”

I almost didn't believe my ears, and hurriedly asked: "What, the fitness ball, it's the ball that sits in the gym and bounces, is that ball inflated, why is it so elastic?" ”

At this time, Sima Qiqi operated the keyboard to search on the computer, and after a while, Sima Qiqi turned the computer screen to the two of them, and looked at Wu Wen at the information written on the computer screen.

Wu Wen took off his glasses at this time and wiped them carefully, and then put them back on and looked at the information of the fitness ball, Wu Wen asked Sima Qiqi for a pen and paper, and began to calculate patiently.

After a while, Wu Wen said excitedly: "That's right, lawyer Sima, you are really smart, if such a big fitness ball is all filled with carbon dioxide gas, when the carbon dioxide is released slowly, because there are two people in the car, the oxygen consumption is faster, and it will indeed make people feel dizzy and inattentive for a certain period of time, at this time, when the driver suddenly falls to the side unconscious, it will make the vehicle make a sharp turn, and the driver's right foot has been stepping on the accelerator, when it is hit by the bump that rushes onto the sidewalk, the driver's foot will step on the accelerator heavier." So in the video you showed me, the vehicle not only did not slow down when it hit the sidewalk, but accelerated and broke the guardrail. ”

Nodding his head and saying, "Oh, this can also explain what we thought was contradictory before, even if the driver dozed off, there was still a passenger who should be able to warn, but the passenger didn't remind him." However, the fitness ball seems to be very elastic, those who practice the fitness ball sit in various postures but the fitness ball has not shrunk or burst, the air tightness should be very good, how to make the elastic ball leak? ”

Sima Qiqi pressed the phone and asked Xiao Yan to enter the office. Curious why he asked Xiao Yan to enter the office, Sima Qiqi asked calmly: "Xiao Yan, I know that you love fitness very much, have you ever practiced fitness ball, how do you do it if you want to make the fitness ball leak?" ”

Xiao Yan told Sima Qiqi that the fitness ball has an airtight valve, and if the valve is not closed, the air in the fitness ball will be slowly exposed, but it will also be very slow, and if the valve is too loose, then the gas will make a hissing sound.

Sima Qiqi thought for a while and said: "If the trunk hisses, it will definitely be heard by the second deceased, if you tell the driver, then you will stop and get out of the car and open the trunk, so the plan to kill people will definitely not succeed." ”

Touching his chin, he slowly asked, "What kind of material is Xiao Yan's fitness ball, which is full of elasticity?" ”

Xiao Yan was stunned for a moment by this question, and slowly replied: "The fitness ball is made of PVC material, with a diameter of 65~75 cm. ”

Hearing Xiao Yan's introduction of the fitness ball, he suddenly laughed and told everyone that he thought of a very simple way, use a needle to pierce a few holes in the fitness ball, so that it would be faster.

When Wu Wen heard this, he was also a little unconvinced, and said: "Eh, don't think about it, practice is king, just go to the school laboratory and try it." ”

The four of them came to the laboratory of the College of Arts and Sciences, and brought Xiao Yan with them because Xiao Yan had a fitness ball, although it was cruel, but they had to let Xiao Yan know what they were going to do. There was an experimenter on Wu Wen's side who actually drove the same car, so he was forcibly requisitioned by Wu Wen to use it for experiments. After a few hours of busyness, I realized how many holes I needed to put in the fitness ball to reach the concentration of carbon dioxide poisoning for two people in the car in a certain amount of time.

After the experiment, he clapped his hands and praised again and again: "The world is really beautiful, I didn't expect that the progress of science and technology is so powerful, and even these can be detected, but even if we think of a car accident with carbon dioxide in the fitness ball, there is a problem, how can we prove that the carbon dioxide in the fitness ball is not an accident or it is artificially released?" ”

Wu Wen fell into deep thought when he heard this, and Sima Qiqi and Xiao Yan did not speak. At this time, the experimenter who borrowed the car before said slowly: "The fitness ball is made of rubber material, and the intact and notched fitness ball must be different from the fire." ”

When Wu Wen heard the experimenter say this, he became interested and said excitedly: "What are you waiting for, quickly take the fitness ball to do the experiment, but only this experiment is not easy to do, and it needs to be controlled." ”

Suddenly, Wu Wen thought of a way to ask several graduate students to broadcast the whole school to find a fitness ball, but he really didn't expect that in this way, he really found a fitness ball with the same size and size as Xiao Yan's, and the student's eyes were red and he watched his fitness ball being burned.

Sima Qiqi saw that Xiao Yan's expression was not very good, so he hurriedly bumped his elbow with him, and saw Sima Qiqi pointing at Xiao Yan and the student, and comforted: "Thank you two for your strong support, you can go buy a fitness ball again and find me with the invoice......"

Sima Qiqi heard that he was puzzled, and he couldn't believe his ears.

Unexpectedly, before he finished speaking, he continued: "My friend, Professor Wu Wen, asked him for reimbursement." ”

When Sima Qiqi heard this, he shook his head with a wry smile in his heart, at this time, the combustion experiment had been completed, and the two fitness balls had completed their mission and turned into two pieces of coke.

Pointing to the two pieces of coke in front of him, he cautiously asked, "This fitness ball has turned into coke, can you find out if anyone has pierced it in it?" ”

Several experimenters looked at each other and smiled, and explained to everyone that the rubber shrinkage direction around the hole of the fitness ball is consistent with the direction of the flame, while the contraction of the hole of the complete fitness ball is inconsistent with the direction of the flame. Looking at the puzzled expressions of several people, an experimenter told everyone that because there is no communication between the inside and outside of the complete fitness ball, the flame will melt at a high temperature before the fitness ball will appear and a hole will be burned in, and the hole that has been pierced will directly expand the gap because the flame can directly burn into the inside.

At this time, I looked back and saw the corners of Sima Qiqi's mouth raised, it seemed that the case was coming to an end, and at this time, the time for the start of the death coroner's ruling had entered the final countdown.

After more than a week of investigation, Sima Qiqi already knew that the car accident was man-made, and on the day of the death hearing, he felt very strange as soon as he walked into the courtroom.

This is the first time I've seen a tribunal like this. I found a seat in the auditorium and sat down, and at this time, I saw a lot of people in suits coming in, and I was feeling strange, and then I saw Sima Qiqi and the client sitting down next to him.

Seeing that Sima Qiqi was very puzzled, he patted Sima Qiqi and asked in a low voice: "Lawyer Sima, why are you sitting here, and why are there so many lawyers, do you need many lawyers to attend the death inquest?" ”

Sima Qiqi was about to answer, when the judge walked in, and the sound of conversation in the auditorium stopped abruptly.
