Early the next morning, Zhou Yinglin spread the news of the mother and daughter in the police station, and with the enthusiastic funding of colleagues in the police station, she raised more than 10,000 yuan.

But before Zhou Yinglin and Lin Shu came to visit the poor mother and daughter, the phone of the forensic department rang first.

"A female deceased is suspected of committing suicide, but the fact that the door of the deceased's home is open makes the local town police station a little suspicious. Just judge the nature of death, let's go to Xiao Lin and Xiao Zhou. Director Liang reported the content of the call.

The two people who received the order immediately took all the tools and rushed to the scene.

The scene is located in the old town of Shuangsha Town, which is like a slum in a TV series, dilapidated and barren, with rows of garages converted into single rooms for people living in need, and the police cordon is pulled in front of one of them.

"Hello comrades from the district bureau, I am Xu Lei, the captain of the Shuangsha Police Station detachment." Before approaching the cordon, a middle-aged man with a smile took the lead in coming over to say hello.

"Brother Lei, are all the bicycle rooms on the site full?" Years of forensic experience have made Zhou Yinglin a habit of understanding the situation before entering the scene.

"Dissatisfied, only 3 of the 16 rooms were occupied. If you don't really have money, few people will live in this kind of garage where you have to find a public toilet even to go to the toilet. Xu Lei said and leaned to the side, letting the two of them cut the whole picture of the garage rental house as much as possible.

"What about the scene?"

Xu Lei pointed to a garage on the far left and said: "The informant is Sister Zhao, who lives in the garage on the far side, and usually goes out with the deceased every morning to the talent market to find casual workers. This morning, when I arrived at the appointed time, I didn't see the deceased, so I went to the deceased's house to check, found that the door was not locked, went in and found that the deceased was already cold, and then called the police. ”

After learning about the case, the two crossed the cordon and began to put on the necessary investigation clothes.

At this time, the crowd outside the cordon had already gathered, and there were discussions in the crowd from time to time.

"Isn't it just my husband who died, what can't I start over, I have to think about suicide."

"She also has a sick daughter, who will take care of his daughter when she dies, she has the courage to die, why don't she have the courage to survive?"

"Her parents raised her so big, and they repaid their parents like this?"

The disdainful ridicule and regretful sighs that kept coming from the surroundings fell on Lin Shu's ears, Lin Shu looked at the group of "sensible" and "rational" people in front of him, and wanted to vomit in his heart, but he didn't know where to start. This group of people is the only one who does not realize how inappropriate it is to say such things in the face of tragedy.

"By the way, what is the name of the deceased?" Zhou Yinglin, who had changed her clothes, asked casually.

"Cai Peiyi."

Hearing this name, Zhou Yinglin seemed to be stunned for a moment. Lin Shu, who was walking in front, looked back at her, "What's wrong?" ”

"It's nothing, it's just that Yiyi's mother happens to be called by that name, but it shouldn't be that coincidental."

Before the words could be completely settled, Zhou Yinglin, who had just stepped into the door, gasped, Lin Shu's pupils began to tremble, and the two of them froze in unison, and the pale, stiff and familiar face crashed into their eyes.

The scene in front of them hit the two of them like a thunderbolt on a sunny day, and people who were alive yesterday are now lying quietly like this.

It was Lin Shu who was the first to recover from his grief, and he began to ask Xu Lei about the situation, "What is the preliminary judgment of the cause of death?" ”

"The emergency doctor said that it should be hemorrhagic shock caused by gastrointestinal erosion caused by taking a large amount of ibuprofen." Zheng Lei said as he pointed to a completely empty jar of ibuprofen on the bedside table, and a few pills were spilled on the ground.

Zheng Lei is also an old policeman, and then continued: "The property at the scene was not lost, and the deceased's wallet and mobile phone are still there." As for the on-site trace inspection, the ground is paved with red bricks, plus the police and emergency personnel who enter and exit the scene, and the shoe prints are basically not much hope. On the doorknob, there was still a pill bottle, and we tried to extract fingerprints. ”

"How do you deduce that the deceased may not have committed suicide?"

"There are two aspects, on the one hand, the deceased agreed yesterday that Aunt Zhao would meet today, and it is unlikely that she will commit suicide that night after making an appointment, and the second is that the door of the deceased was hidden when she was found, according to Aunt Zhao, the deceased usually lived alone because she was a young woman, and she was relatively cautious, so there would be no such situation of not closing the door."

Lin Shu nodded after thinking for a while, "Okay, then I'll leave it to me and Forensic Doctor Zhou." ”

Lin Shu approached Zhou Yinglin's side and said softly, "Are you better?" ”

Zhou Yinglin took a deep breath, pursed her lips and nodded, and then officially began the autopsy work.

Zhou Yinglin looked at several bottles of unopened ibuprofen in the cabinet, "She should be in pain, she must have accumulated a lot of overwork injuries in her body with so many jobs, so she needs such a large amount of ibuprofen to delay the pain." ”

Lin Shu struggled to recall the contents of the book, "Excessive consumption of ibuprofen can cause gastrointestinal irritation, nausea, vomiting, abdominal pain, bloating and even diarrhea, and in severe cases, it can also cause dehydration, internal organ failure, and shock. Who would have made up their minds to commit suicide in this way if it weren't for the unbearable pain. ”

The two of them observed a moment of silence, then bowed to the corpse, "Let's begin." ”

"It's about 9:30 a.m., and the anal temperature of the corpse has dropped by 10.5 degrees, according to the first ten hours of the hour drop of 1 degree, the second hour of the drop of 0.5 degrees, should have been dead for 11 hours." Zhou Yinglin used a voice recorder to record the situation of the corpse.

"The body showed signs of struggle, but it was difficult to tell if it was from the fight or from the severe pain caused by an overdose."

At this time, a light-colored scar on the skin under the short sleeve of the deceased's right hand attracted Lin Shu's attention, and he began to gently wipe the scar with alcohol, the scar became more and more obvious, and then he looked at the other hand and found that there was also the same scar.

"Brother Hard, do you think these two injuries seem to be caused by the deceased being pressed by some symmetrical weight, such as the knee?" Lin Shu tentatively put forward his own ideas.

Zhou Yinglin instantly understood what he meant, "You mean that someone knelt on the chest of the deceased, pressed his knees and arms to control the deceased?" ”

Lin Shu nodded and continued to add, "The reason why he wants to use his knees to control the deceased's hands is because he wants to keep his two hands to give medicine to the deceased. ”

Zhou Yinglin, who had a tacit understanding, decisively took Lin Shu's words, "In other words, we only need to check whether the mucous membrane of the deceased's mouth and nose is bleeding, and we can roughly confirm whether this is suicide or he killed him." ”

As expected, the oral mucosa was bleeding, and two teeth were obviously loose, which could basically be judged to be murder.
