The police car stopped at the entrance of the small building, and everyone saw that there were four or five people surrounding Ge Dongyun's house. Some of these people are carrying cameras, while others are simply holding mobile phones, it seems that they are all journalists. Not far from the small building of Ge Dongyun's house, there are some residents in the community watching from a distance.

These people were chatting and talking about Ge Dongyun's death.

"We just received a notification from the informant that Ge Dongyun has been killed by the murderer."

"Right now we are downstairs from Ge Dongyun's house, but Ge Dongyun's mother won't open the door for us anyway."

"Brothers, I'm at the scene, I belong to this community. I heard that Ge Dongyun is dead, eh, the police came over from behind."

Hearing the young man's words, reporters gathered around and asked the members of the task force various questions. As Shao Lao walked forward with a few people, he said, "Everyone, please, we are here to investigate the case, not to be interviewed."

Saying that, Shao Lao looked at Yuan Jun: "Yuan Jun, stay at the door, don't let anyone in."

"Understood." Yuan Jun stretched out his hands and stopped the reporters in front of him: "Everyone, please cooperate with the work of the police, stand where you should stand, and don't cross the line casually."

But at the same time, Lao Shao's mind was filled with a question—how did these reporters know that Ge Dongyun was killed.

"Mother Ge, open the door." Elder Shao pressed the doorbell.

Moments later, Mother Ge opened the door.

Mother Ge's eyes were red and swollen, and her face was covered with tears. The white dress she was wearing was covered in blood, and her arms were also covered in coagulated blood. Beside Ge's mother, a security guard was standing there. When he saw the police coming, he nodded slightly at everyone.

Seeing the arrival of the members of the task force, Mother Ge's tears burst again.

"Hey, condolences." Xu Yiman walked up and patted Mother Ge's back lightly.

Although Mother Ge is already the mother of a child, she is only twenty-seven years old, a few years younger than Xu Yiman. Such a life change is not something a weak woman can bear. It's okay for Xu Yiman not to comfort him. As soon as he comforted him, the sadness and grievances in Ge's heart surged out, and he couldn't control it.

Jiang He ignored this and asked directly, "Is Ge Dongyun's body in the bedroom on the second floor?"

Mother Ge nodded.

Shao Lao looked at Ge's mother and said, "The most urgent task is to find the murderer first. My condolences, I know you are in a very sad mood right now, but the time is short. One more minute to check the scene will give you one more chance of winning."

"Okay..." Mother Ge nodded, and then, with the help of Xu Yiman, followed Mr. Shao to the second floor.

Jiang He took the lead and stood at the door of Ge Dongyun's bedroom on the second floor, looking inside.

As Mr. Shao walked upstairs, he said, "When did you find out that Ge Dongyun died? Tell me about the process in detail, and don't miss any details."

Mother Ge replied: "Dongyun has been up late these days, because she doesn't go to school, so I only come back to make breakfast for Dongyun after I send my son Dong Ai to kindergarten, and then ask her to eat. Every time I come back, it's about 8:40, and it should be about 9:00 when the meal is ready."

"After that, I called Dongyun to eat, but I waited for more than ten minutes and she didn't come down. She doesn't usually do this. I only have to call a few times each time. Although she won't agree, it won't take long. Open the door and come down to eat. I wondered if Dongyun was not feeling well today, so I went up to the second floor and knocked on the door."

During the speech, Ge's mother could hardly control it, so she couldn't speak.

Xu Yiman patted her on the shoulder, and then Mother Ge continued: "I shouted outside the door for a long time, but she didn't respond. I thought it was very strange, and I wondered if Dongyun had gone out. But I Called her and heard the ringing coming from her bedroom. I took the backup key and tried to open the door, but the door was locked from the inside and no one else could open it with the key from outside."

"It means that Dongyun is in the house, but no matter how I shout, she just doesn't open the door." Mother Ge said as she recalled, "I was a little scared at the time because I was afraid that Dongyun was sick, so I called the property. , the security guard is here."

The security guard nodded and said, "We received a call from Ms. Wang, and the property sent me over. At Ms. Wang's request, I slammed the door open with her."

"After I went in, I saw Dong Yun lying on the bed with her back to the door. Logically speaking, with such a loud voice, why should Dong Yun get up, but she didn't move. I ran over quickly, but my As soon as my hand touched the quilt, I felt that something was wet. I stretched out my hand and saw that it was blood. I lifted the quilt and the bed was covered in blood. I was completely stunned. I hugged Dongyun and shouted. She, but she's dead, has a knife stuck in her chest."

Mother Ge cried and said, "She has no pulse, no heartbeat, and even the wound doesn't bleed out..."

The security guard said: "At that time, I conducted a simple inspection on Ge Dongyun and found that she was dead. After that, Ms. Wang informed you, and we are here waiting for your arrival."

"If that's the case, it looks like he's been dead for a while." Xu Yiman said with a sigh.

While the others were talking, Jiang He had been standing in the doorway of the bedroom observing for a while. The last time Jiang He came, Ge Dongyun's bedroom was clean and spacious, but after this visit, Ge Dongyun's bedroom was a mess - the chair that Lao Shao used to sit on fell to the ground, and a blood-stained quilt was piled on the ground. Books on the table and water glasses filled with water were scattered all over the place.

On the bed, there was Ge Dongyun's body lying flat. On Ge Dongyun's left chest, a western-style kitchen knife had penetrated without roots. From that position, it was the heart. Judging from the position of the dagger handle, the kitchen knife is parallel to the ribs, piercing through the intercostal muscles, and is hardly blocked by the ribs, so it can penetrate without root.

After standing at the door and taking pictures of the crime scene, Jiang He put on his white gloves and walked in, with Lao Shao following behind. Xu Yiman comforted Mother Ge a few times, and walked in with his equipment.

This bedroom is large and spacious enough, with a wall of closets that run the height of the house, and on the other side, a smaller ensuite that looks like a bathroom.

The bed was placed in the middle of the room. This large bed seemed to be more than enough for three people, and Ge Dongyun was on one side of the bed.

Xu Yiman looked at Ge Dongyun, and gently opened Ge Dongyun's eyelids with her hands. Then, she pinched Ge Dongyun's biceps. After that, Xu Yiman said, "The eyeballs are not cloudy yet, by pressing The muscles of the deceased can feel a weak muscle hypersensitivity response."

After speaking, Xu Yiman touched Ge Dongyun's jaw again and said, "The corpse has just formed, usually starting from the lower jaw and gradually spreading to the whole."

"The corpse will occur within one to three hours after death, and the muscle hypersensitivity reaction will occur within two hours after death. By comparing the temperature and humidity at the scene, the approximate time of death can be obtained as a About half an hour ago, which is about 8:20. To get a more specific time of death, a complete autopsy is required."

With that said, Xu Yiman looked at the western kitchen knife stuck in Ge Dongyun's body again.

"The kitchen knife pierced through the gap between the fourth and fifth ribs. The location was very accurate. Even without much effort, the heart could be easily pierced." Xu Yiman frowned and said: "This kind of Western-style kitchen knives have tiny serrations in front of the blade, like small blood troughs, even if they don’t pull them out, Ge Dongyun’s bleeding will be huge.”

"I didn't find any other wounds on Ge Dongyun's body, and from the current situation, it is inferred that the bleeding caused by the rupture of the heart and the insufficient blood supply to the brain are the most direct causes of death."

Xu Yiman lightly touched the handle of the knife with his hand, and added: "The murderer is very professional and has certain medical knowledge. He placed the knife parallel to the ribs, and chose between the fourth and fifth ribs, Almost killed by a knife, Ge Dongyun didn't even have time to call for help and struggle."

"The murderer is deliberate." Shao Lao said: "This way he will not be discovered and will not cause a commotion, but the question is, how did the murderer get in?"

After speaking, Shao Lao looked at Ge's mother and asked, "Do you know what time Ge Dongyun gets up every day?"

"I'm not too sure, maybe if I don't call her, she'll just sleep all the time..." Mother Ge said with her head lowered.

Jiang He asked, "Are you sure the door is locked?"

Mother Ge nodded: "As soon as she returns to the room, she will lock the door. I know that she has never been very fond of talking to me, nor does she regard us as her family. She usually treats herself as a People are locked in the house, and I don't know what she usually does."

The security guard also said, "I can testify that the door was locked backwards. At that time, I tried to push the door and tried to open the door with a key, but they couldn't open it. In the end, there was no way, so I slammed the door open with Ms. Wang."

When the two were talking, Jiang He was not idle. He kept observing the door lock. Neither of them lied. Before the door was violently broken open, the door was indeed locked. And once this kind of lock is locked from the inside, even if the person outside has the door key, it will not help, and can only wait for the person inside to take the initiative to open the door.

Jiang He walked to the window again, and found that the window was locked from the inside. This is a common sliding window. The left sash faces inward and the right sash is outside. There is a crescent lock on the left window. This kind of crescent lock can move up and down 180 degrees. When the lock handle is facing up, it means that the window is not locked. , when the lock handle is down, it means the window is locked.

Jiang He noticed that although the handle of the crescent lock was facing down, it was not perpendicular to the ground, but had an included angle of about twenty degrees. At the same time, he also noticed that the lock was not damaged by violence. He tried to push and pull it left and right, but the window remained motionless and could not be opened.

There were no signs of damage to the door or windows, Jiang He thought about it, and walked quickly into the bedroom's suite, which was the bathroom. The bathroom had a bathtub and toilet, but no windows, it was a closed space.

"The entire bedroom is one big secret room!" Jiang He said.
