Police Chen Shu

When they saw Ma Rongcheng's nose almost touching the deceased's lips, everyone realized that he must have discovered something extraordinary.

"Expert Horse, have you discovered anything?" Huang Mao approached and asked in a low voice, for fear of disturbing the expert's discovery.

Ma Rongcheng hummed twice. Although the answer was vague, it was enough to arouse everyone's curiosity.

Everyone gathered around and looked at it for a long time but found nothing.

Chen Shu followed Ma Rongcheng's gaze and looked at the deceased's neck. It was a deep mark that circled half a circle around the neck. Naturally, it was the mark of the thick rope tightened when hanging.

Chen Shu stared at the traces, and the scene of the deceased hanging himself on the toilet doorframe emerged in his mind: he stood on the chair, put his head into the noose, then kicked off the chair and hung himself up.

Wobbly, wobbly.

She struggled continuously at first, but because her throat was tightly strangled by the rope, her pupils slowly lost focus, and her hands that were originally holding on to the rope dropped weakly.

The scene finally freezes on the scene where the old man's tongue is stretched out.

And bulging eyeballs that are about to burst.

This is a scene of fierce struggle that is both desperate and lonely, until everything returns to peace.

In an instant, the light in Chen Shu's eyes skyrocketed, and he came to his senses: "Strangulation mark! This strangulation mark is abnormal!"

Zhu Yiba, who claimed to be the best in martial arts, always had a grimace on his face. He took a deep breath now, as if he had been waiting for this moment, and said excitedly: "Chen Da, you really saw the problem!"

Jiang Hai couldn't stop trembling all over, as if he was about to witness the excitement of a great scene.

Huang Mao also looked at Chen Shu with extremely expectant eyes.

"Our Conan book is not just a boast." Chen Chuan chuckled, slowly took out yellow cigarettes from his pocket, and handed them to several people one by one, looking proud.

Forensic doctor Old Tang showed a pleased smile, feeling that he had done the right thing by involving these people in handling the case. At this time, he was just waiting for this brother from other provinces to reveal the secret.

Ma Rongcheng stood up straight, ready to listen to what this little brother had to say. Although he had noticed something unusual before, the reserve of the provincial expert made him feel that remaining silent was also a good practice.

At this moment, everyone's eyes were focused on Chen Shu. Chen Shu, who was still a little hesitant at first, was now quite sure and said calmly: "This strangulation mark is too clean."

"Clean?" Jiang Hai's eyes flashed. He felt that this scene of standing next to the corpse and learning and applying it was really exciting. It was much more exciting than the glasses teacher who always made people fall asleep in the criminal investigation technology class. "Brother Shu, you Does it mean that the neck of the deceased was too clean? Did she take a bath first and then hang herself? Wait, take a bath first. Could it be that she was preparing to do that with the man? The murderer was his boyfriend! "

The more Jiang Hai talked, the more excited he became, almost screaming out of his chest.

Chen Chuan couldn't help but laugh, and joked: "I didn't expect you to know the procedures in this area quite well. Tsk, tsk, I thought you were a virgin before. I underestimated, I underestimated."

Jiang Hai, who was extremely excited, felt like a car that was speeding on the highway was stopped for no reason by Chen Chuan's harsh comment. His face turned red and he suddenly became breathless.

"Well, let's change the adjective, clear, the marks of strangulation are very clear." Chen Shu did not continue the fight between the two, with a serious expression, and made an assumption, "Imagine, if a person hangs himself, even if it was voluntary before, But it must be very painful during the hanging process, so there will be a certain degree of struggle.”

"Yeah!" Jiang Hai closed his eyes, imagined a scene of a person hanging in his mind, and then nodded heavily.

Chen Shu pointed at the neck of the deceased and said thoughtfully: "Look at the strangulation marks. There is no overlap or displacement, which means that the deceased did not struggle fiercely before death. I have seen several cases of hanging suicide before. , the traces of the rope hanging around the deceased's neck must be overlapping and not so clear. Therefore, it is very likely that she hanged herself unconsciously, that is to say."

"Brother Shu! Do you mean that there was a second person hanging the deceased on the rope at the scene? In other words, the deceased was hung up after death!" Jiang Hai's eyes were shining, his hands were rubbing each other, and he was very emotional, " Murder! Murder!"

Chen Chuan deliberately stepped forward with a straight face and slapped Jiang Hai on the back of the head, teaching him a lesson: "A damn person is so happy? Are you still acting like a policeman?"

Being slapped with such a big label about morality, Jiang Hai immediately turned off his fire, smiled and stopped making noise.

Here, Chen Shu subconsciously looked at Ma Rongcheng, who was the first to notice the abnormality in his neck. The others followed Chen Shu's gaze and looked over.

Ma Rongcheng chuckled and nodded: "Officer Chen, your statement has some truth, but there are still doubts. The problem is that you have seen too few people who hanged themselves, and there are too few samples, so there will be bias in generalization.

"If the deceased struggled before death, the flame retardancy of the strangulation marks would be complicated, but if he died immediately at the moment of hanging, the strangulation marks would be like this corpse."

Ma Rongcheng paused for a moment, pointed his right hand straight at the corpse on the autopsy bed, and said calmly: "It's very clean and clear."

"Die instantly?" Jiang Hai was stunned and caught the key to Ma Rongcheng's explanation, but he still couldn't figure out how he could die instantly by hanging himself. Didn't those people in the movie have to struggle for a while before spitting out their tongues and burping?

Ma Rongcheng enjoyed the teachings of this kind of teacher and said patiently: "Some people will lose consciousness and cannot move their hands and feet the moment they hang themselves. Moreover, during this process, people feel no pain at all, so they will not struggle. "

Ma Rongcheng habitually paused for a moment, giving everyone enough time to think, and then said slowly: "There is another situation. That is, during the half second of hanging, the hanger uses too much force on the rope and will Causes the neck joint to dislocate suddenly, in which case the heart and breathing will stop immediately.

"In addition, if the rope happens to compress the carotid sinus, it will increase the vagus nerve tension and cause reflex cardiac arrest. The person will also die immediately. In other words, there will still be the situation where there is no struggle as mentioned by Officer Chen. .”

"Ah? Teacher Ma, do you mean to commit suicide?" Jiang Hai suddenly felt that his chest was empty, and most of his energy was drained from his body. He was quite disappointed.

Ma Rongcheng nodded: "It's very possible."

"Hey." Jiang Hai sighed, his eyes gradually dimmed, and for some reason, his feet went limp and he fell on the chair.

Chen Chuan couldn't stand it anymore, so he kicked him and scolded with a smile: "You kid, what a bastard you are!"
