In the bedroom, forensic doctor Jiang Xiran and forensic assistant Zhou Xiaoyi were conducting an autopsy at the scene.

Unlike the previous murder scenes, this one was very clean, with no murder weapons and no blood.

The deceased was a man named Sun Jinyu, who was the owner of the house.

He was lying on his back on the floor next to the bed, his body showing signs of being moved, his shirt unbuttoned, and a slight subcutaneous hemorrhage on his chest, which was supposed to be caused by the first aid of the 120 emergency doctor.

"The deceased's face was pale and dim, his pupils were blurred, his eyes were sunken, his lips were cyanotic, his clothes were soaked with sweat, and he was seriously dehydrated. On the surface of the cadaver, it is indeed consistent with the signs of insufficient pumping due to heart failure in myocardial infarction, resulting in peripheral circulatory ischemia. ”

Jiang Xiran examined the body and came to the same conclusion as the 120 emergency doctors.

These words were heard by Lu Ke, who was standing at the door of the bedroom, and he walked quickly to Jiang Xiran's side and asked, "Is it really a sudden myocardial infarction?" ”

Jiang Xiran stood up, looked at the male corpse in front of him, and said in a deep voice: "Judging from the surface of the corpse, it is indeed in line with the situation of sudden myocardial infarction. The exact cause of death will need to be autopsied to be known. ”

Lu Ke nodded: "Since some people question the cause of death, then take it back for an autopsy and make an autopsy report." ”

Jiang Xiran greeted Zhou Xiaoyi, preparing to take the body back to the forensic department for an autopsy, and then asked, "Is there anything found at the scene?" ”

Lu Ke looked back at the living room, the technical team was still busy, collecting fingerprints and footprints and other traces of the scene, and said lightly: "Judging from the situation at the scene, someone has indeed been here, and there was a fierce quarrel with the deceased. Judging from the angle and extent of the shattering of the glass, as well as the distribution of the fragments, it does not look like it fell to the ground, but it was dropped on the ground. ”

Jiang Xiran pursed his lips and asked again: "Could it be that there was a quarrel, which caused the deceased to be emotional, his heart beat faster, and his blood pressure to rise, which induced heart disease?" ”

Lu Ke replied: "This possibility is very high, and there are too many cases of people who are angry. ”

"A young man in his thirties was killed by popularity, and he died a really wretched death." Jiang Xiran said lightly and walked out of the bedroom.

In the living room, the cleaner Sister Liu stood obediently in the corner of the wall, not daring to move, for fear of destroying the scene.

Seeing the forensic doctor come out, he hurriedly asked, "How is it?" Did you find out? ”

Lu Ke walked up to Sister Liu and explained the situation to her: "We will conduct an autopsy on the body to further determine the cause of death." ”

Then, Lu Ke asked her again: "What about Sun Jinyu's family?" Can you get in touch? ”

Sister Liu shook her head: "I don't know, I only know that he was married, but his wife seems to have passed away, and his parents don't know." ”

Lu Ke frowned slightly, twisted his fingers, and suddenly asked her, "Does Sun Jinyu have any enemies?" ”

Although on the face of it, the deceased did die of a sudden myocardial infarction, if there was a quarrel and a heart attack was induced, then this case cannot be recognized as an accidental death alone.

It is often said that a person who dies of anger does not pay for his life, but legally speaking, whether or not he bears criminal responsibility still depends on the subjective fault of the person concerned.

If the other party deliberately provokes death by knowing that the deceased has a heart attack, and allows such a result to occur without help, it is an intentional crime.

Similarly, depending on the degree of the situation, there may be negligence, civil liability, and so on.

Sister Liu thought about it carefully, and suddenly as if she had thought of something, her eyes widened, and she said excitedly: "I'm not sure about the enemy, but there is a person who has quarreled with Mr. Sun!" ”

Lu Ke felt a little surprised, and hurriedly asked her, "Who?" ”

Sister Liu took a deep breath and said seriously: "There is a man, big and tall, very fair-looking, wearing glasses and a small flat head, who seems to be a friend of Mr. Sun." ”

Sister Liu tried her best to describe the person's appearance to Lu Ke, although there were many descriptions, but as a case investigation, they were too ordinary and had no characteristics.

After all, Sister Liu is just a cleaner and has no criminal investigation training, so it is okay to be able to depict these.

Lu Ke nodded as he listened, found the opportunity, and interrupted her description at the right time: "Sister Liu, do you know what that person's name is?" What does he do? ”

Sister Liu's eyes glanced at the ceiling, recalled carefully for a while, and said in a deep voice: "Mr. Sun seems to call him Brother Ren." ”

"Is his surname Jen? Or does it have the word ren in the name? Lu Ke asked.

Sister Liu shook her head: "I don't know about this." ”

Lu Ke looked at him and asked, "Have you ever encountered the two of them quarreling?!" ”

After listening to this, Sister Liu nodded vigorously, nodding very hard every time, as if she was trying her best to prove the authenticity of her description with this subconscious action: "I have encountered it!" Encountered! I've met it many times! ”

Lu Ke invited Sister Liu to the corner of the sofa in the living room and sat in a position with no traces of physical evidence: "Sister Liu, tell me what you know in detail." ”

Sister Liu took a deep breath, as if she remembered Mr. Sun's death, and tears gleamed in her eyes again.

"That guy named Brother Ren seems to be Mr. Sun's business partner, and I saw him several times when I came to clean Mr. Sun before. When I met before, they all hooked shoulders, talked and laughed, and seemed to be very close to each other.

Mr. Sun is a polite and polite person, but he doesn't seem to have any friends, and I haven't seen anyone else except this Brother Ren.

But this year, especially the last few times I went to clean up, I could always see him arguing with Mr. Sun, and on one side Brother Ren was angry, and Mr. Sun sat on the sofa without saying a word.

When they saw me come to the door to clean, they did not shy away from it, and continued to quarrel in the living room, as if they couldn't see me.

The content of each of their quarrels is basically the same, as if they are discussing business matters, what prices are high, and how they will develop in the future, I don't understand very well. ”

Lu Ke nodded and continued to confirm with him: "You often see them arguing? ”

Sister Liu replied: "Well, especially in the last few times, I can meet them quarreling every time. ”

Lu Ke didn't ask again, but fell into deep thought.

Mo Yufei, who was standing beside Lu Ke, recorded Sister Liu's description in detail in her notebook, and couldn't help but ask: "Sister Liu, do you come here every half a month?" ”

Sister Liu glanced at Mo Yufei, nodded and replied, "Yes, I came on the 1st and 15th of each month, and if there is any change, Mr. Sun will tell me in advance." ”

Mo Yufei frowned, and suddenly muttered: "This is too coincidental, isn't it, the first and fifteenth of each month have a fixed quarrel?" ”
