The windows were open as wide as possible, but it was obvious that in such a narrow space, it would be impossible for anyone to get in and out of this space unless they were a quarter of old London.
Cheng Yu glanced at Old London subconsciously, wondering if it was possible that there was no so-called murderer at all, but that it was actually Old London who killed someone?
This thought just passed by in a flash, and Cheng Yu didn't delve into it deeply.
Looking in through the open window, I saw Bai Xiaowen lying on the ground, motionless. Her posture was a bit strange, her hands and feet were not in their normal positions, but twisted at weird angles.
It's not the kind of posture where one's hands and feet are broken after falling from a high altitude. It's just that no matter what way a person lies down, his joints should not be twisted like that. Unless Bai Xiaowen was doing it before he died.
A violent struggle.
"When you came here before, were the curtains open like this?" Cheng Yu turned around and asked.
"Before, the curtains were closed, and we could only see that the windows were open, but we couldn't see what was going on in the house at all. Then, I opened the curtains, and I was frightened by what was going on in the house, so I just
It opened such a small gap."
It was Su Xi who explained the situation, and Cheng Yu nodded to her.
Cheng Yu carefully checked the latch that locked the terrace glass door. The copper lock was still hanging on it. Cheng Yu tried to pull the latch, but it was obviously blocked and could not be opened at all. This meant that the door must be open.
It cannot be opened. Even if Bai Xiaowen unlocks it from the inside, it is impossible to open the door.
"Can you ask Old London to open the door now?" Deng Jingliang urged, obviously impatient.
Cheng Yu stood up, nodded and said, "Let's go."
Everyone went back to the balcony of the spare room, passed through the room, and finally returned to the corridor.
Old London took out the key and opened the big copper lock hanging on the door of Bai Xiaowen's room.
Cheng Yu watched the process of unlocking very carefully, not missing even a single detail.
No problem, the copper lock is hung on the latch in perfect condition, and the process of unlocking the lock in Old London is also very normal. Cheng Yu took the copper lock from the latch himself.
Then Old London took out the universal key card and inserted it into the door lock slot of Bai Xiaowen's room. The door unlocking sound sounded as promised, and the green LED light flashed to inform everyone that the door was open.
"Then, I'm opening the door." Cheng Yu turned around and said to the others. After everyone nodded, Cheng Yu pressed the door handle and pushed the door inward.
The living room was empty, everything was in its place, as if no one had ever entered the room.
Because they had learned about this before, Cheng Yu, Liu Manman and Deng Jingliang were not surprised, but just pretended to be a little surprised in response to the questions of Guo Ping'an, who was obviously surprised.
"Is this room really Bai Xiaowen's room? Why does it feel like no one has been in this room..." This sentence was said by Su Xi, and everyone agreed.
Guo Ping'an said: "It seems that this girl has very serious obsessive-compulsive disorder."
"So, her window is obviously abnormal. Even if she knows that the window will basically not affect anything, it is impossible for a person with strong obsessive-compulsive disorder like Bai Xiaowen to keep that window open all night. So.
, the window can only be opened by the murderer."
Cheng Yu made the above conclusion, or reasoning, which was recognized by everyone.
"Okay, I'm going to go in now, but before I go in, I'd better ask Old London to go in first. After confirming all the furnishings in the room, I will enter again, in order to avoid anyone thinking that I have concealed something or changed some clues."
These words are basically consistent with what Cheng Yu said before entering Chen Yu's room yesterday. This is not a pretentious gesture by Cheng Yu, but an attitude.
Old London entered the house. Since the living room seemed as if no one had ever moved in, Old London checked very quickly.
Immediately, Cheng Yu walked in first and then let everyone in.
This is different from Chen Yu's room. Since the crime scene in Chen Yu's room was in the living room, others had to wait for Cheng Yu's autopsy to be completed before others could enter the room. But Bai Xiaowen's crime scene was in the bedroom inside, so everyone
Everyone can enter directly.
The bedroom door was closed, so Cheng Yu said again: "Then next, I'm going to open the bedroom door."
Because Bai Xiaowen's body could be clearly seen from the window lying beside the bed, Cheng Yu could push the bedroom door open with confidence without worrying about whether the door would hit anything.
Then Cheng Yu still asked Old London to enter first and record all the details of the crime scene. Then he took off his shoes and walked in wearing only cotton socks, which served as shoe covers.
However, this actually has no substantive significance, because the bedroom floor is so shiny that no footprints can be seen at all. Cheng Yu took off his shoes just out of habit.
Walking to Bai Xiaowen's body, Cheng Yu looked at the body that was still alive and kicking last night from top to bottom, wondering if if he had let her go to the wine cellar last night, she would not be dead now.
At the same time, Cheng Yu knew that behind him, there were unparalleled eyes staring at him.
After bypassing Bai Xiaowen's body, Cheng Yu simply squatted down slowly facing the direction of the bedroom door. This angle allowed the five people outside the door to see more clearly, lest anyone use the topic to say that Cheng Yu moved his hands and feet.
.
To everyone, Cheng Yu seemed to be observing the corpse, but in fact, Cheng Yu just entered the system mall interface on the light screen in his brain, redeemed a medical skill, and chose to use it immediately.
After the medical skills took effect, Cheng Yu stretched out his hand and pinched Bai Xiaowen's strangely arranged hands and feet.
Bai Xiaowen's left leg was naturally downward, but her right calf was awkwardly spread out, with her toes pointed toward the outside of her body.
This chapter is not over yet, please click on the next page to continue reading! After pinching, Cheng Yu said: "The knee joint of the right leg is normal and there is no sign of fracture. It should just be that the posture is a little weird."
Bai Xiaowen's right arm hangs normally on one side of her body, but her left arm's shoulder joint is spread out, and the joints of her forearm are facing toward the inside of her body. Her fingertips can barely touch her chest. It looks like
He wanted to touch his heart with his left hand, but he opened it further.
Cheng Yu still checked his shoulder and elbow joints and found that they were both intact, so he told everyone about the situation.
Bai Xiaowen's face was facing the direction of his left shoulder. Cheng Yu reached out to explore the location of the aorta in his neck. He first confirmed the skin temperature and also confirmed that his pulse had completely stopped.
Of course, these are actually just corresponding steps. Bai Xiaowen's death does not need to be verified by whether his pulse is still beating. If the blood that has coagulated on the ground is not mostly absorbed by the small rug beside the bed, it will only
I'm afraid it has already flowed all over the floor.
"It is confirmed that the pulse has completely disappeared. At the same time, it can be clearly felt that the corpse temperature is less than 25 degrees. This may be affected by the open window. From the corpse temperature, the necessary conditions for judging the time of death have been lost. According to Bai Xiaowen yesterday
Judging from the fact that she was still alive around 12:30 p.m., her death time could not have exceeded nine hours at most. If the window was closed, her body temperature at this moment would only have dropped by about nine degrees at most. Let me explain this.
Now, within ten hours after death, the temperature of the corpse will drop by about one degree per hour, but this will be affected by the ambient temperature. In fact, the temperature last night was not too low, and it should not have caused such a drop in corpse temperature.
It had a big impact, but the wind was strong last night, so the rapid loss of temperature should be caused by the sea breeze. From this point of view, I judge that Bai Xiaowen should have died before two o'clock in the morning."
These words made the five people in the living room make surprised sounds.
"Are you sure? Before two o'clock? Old London hadn't started charging at that time. Is the murderer so brave? He actually struck so early?"
What surprised Cheng Yu was that the first person to discuss the matter was Liu Manman, who had never spoken much.
"Yes, Mr. Cheng, is this wrong? Generally, the time of death is judged by body temperature, shouldn't there always be a time period?" Su Xi also expressed her confusion.
"Of course, this is usually the case. If at this time, I can feel that Bai Xiaowen's body temperature is significantly higher than 30 degrees, then my time of death will be within a range, but it is precisely because his body temperature is too low, even if
There must have been a very long period of time due to the influence of the sea breeze. And I am talking about before two o'clock. This is actually still a time interval, but I have omitted the other end, because she must have been at twelve o'clock.
She might not die until after half past o'clock. Didn't everyone lock her door at that time?"
Only then did everyone understand, so they didn't say anything more.
Cheng Yu walked to Bai Xiaowen's feet and reached out to try to break the joints of her ankles. Rigor mortis was already quite obvious, but Cheng Yu did not move.
Cheng Yu had just tried the knee joint and it was movable, which meant that Bai Xiaowen's rigor mortis had only reached the calf.
However, the onset time of rigor mortis is different for everyone. It may start from ten minutes to seven hours after death. However, Bai Xiaowen died less than nine hours, so it is basically difficult to use rigor mortis.
This is used to determine the time of death.
"Rigor rigor mortis should be in the ascending order. Her ankles are obviously stiff and unable to move, but her knee joints are still basically normal. Therefore, her rigor mortis has just developed to the calf area. From this point of view, her death time is one hour
By about eight hours. Judging from the body temperature, I think her death time was between one and two in the morning."
After saying that, Cheng Yu returned to Bai Xiaowen's head, squatted down again, and said, "Okay, I'm going to check the wound now. Judging from my angle and the blood stains on the carpet beside the bed, the cause of death should be cut by a sharp weapon.
Carotid artery."
Liu Manman asked again: "But usually cutting the carotid artery will cause a lot of splatter-type blood stains. I looked out of the window just now, but I didn't see any heavy splatter-type blood stains in the room. Is this
Isn’t it a little strange?”
Cheng Yu nodded, turned Bai Xiaowen's body over from the lying position, and said: "Well, theoretically you are right, but on this point, the case has been solved, and the murderer should have been covered with a bath towel first
Bai Xiaowen's head was cut off, and then his carotid artery was cut inside the bath towel. A large amount of blood spattered out and quickly soaked the entire bath towel, and the bath towel was pressed under Bai Xiaowen's body... This is roughly the situation."
"How can you cut open the carotid artery so accurately when you cover your head with a towel? Has the murderer studied medicine?" The person who spoke was Xie Yanwen. The fat man didn't speak for a while, but as expected, he was clearly targeted as soon as he opened his mouth.
"If you still want to be slapped, just continue." Cheng Yu didn't look back.
