Chapter 62: Mismatched Bloodstains

Du Yu said on the phone that the crime scene was the principal's office of Jiangcheng No. 4 Middle School, and asked two people from the Forensic Department to come quickly because there were too many people at the scene and they were afraid that the body would be damaged, which would be detrimental to the autopsy.

Xu Yiqing and Lin Sheng rushed to Jiangcheng No. 4 Middle School without stopping.

No. 4 Middle School is located at the westernmost end of Jiangcheng City. Further west is the national highway leading to the countryside, with low houses lined up along the way.

At this moment, the entrance of No. 4 Middle School is full of cars, as if there is some important meeting.

After a brief communication with the security guard, the guard let Lin Sheng's Chevrolet pass, so he stepped on the accelerator and drove to the bottom of the administrative building. At this time, there were already several police cars guarding the door.

Xu Yiqing asked: "Ah Sheng, have you been to No. 4 Middle School?"

Lin Sheng obviously knew the campus environment of Jiangcheng No. 4 Middle School. He knew the location of the principal's office without asking the guard.

After getting out of the car, Lin Sheng took out a bag of tools from the trunk and looked at the campus with emotion: "No. 4 Middle School is my alma mater. I studied here for two years before, and my grandmother sent me to the key No. 1 Middle School in the third year. Compared with the study atmosphere of the last year, I still miss the first two years at No. 4 Middle School more."

There were police officers waiting downstairs. When they saw the two people from the forensic department arrive, they quickly led them into the building.

"What's going on at the scene? Why are there so many people?"

Xu Yiqing noticed that there were a lot of people in the administrative building, including students in school uniforms and parents who were obviously older.

The police officer replied quietly: "They all came to see the principal. To put it bluntly, they are giving gifts."

These parents looked flustered and obviously didn't want to get involved.

Who would have thought that they came to see the principal to discuss this year's enrollment for their children, but ended up encountering a murder case. One by one, they left while saying they had urgent matters.

"Please, comrade. I really have something to do later."

"I just arrived. It has nothing to do with me."

The police officers who were maintaining order naturally could not let them go and stopped the parents who wanted to leave the scene.

In addition to the parents, there were several students who were responsible for cleaning the administrative building. They gathered in the lobby on the first floor and looked at a loss.

The students who didn't know what was going on looked around and asked questions, curious about why so many police officers had come, while the junior high school students who already knew that someone had died had horrified looks on their faces, obviously frightened.

"What happened? I just went to the bathroom."

"The principal seems... dead."

So several students who were unaware of the situation began to panic. This was the first time they had seen death up close, and being only in their teens, it was inevitable that they were afraid.

The police calmed them down and told them to go back to their class and see their head teacher, and not to run around or talk nonsense.

Looking at the students' frightened expressions, Lin sighed softly, "Although today's children are tall and strong and mature in thinking, they still panic when they encounter something like a dead person."

Although Lin Sheng couldn't remain calm like his master when faced with a catastrophe, he was used to death.

I don’t know if any of my younger classmates will be able to take over the mantle of Jiangcheng Forensic Medicine in the future.

The police officer said: "The body was found in the morning. The first person to discover the body was the security guard of the administrative building. He is now upstairs with Captain Du."

The principal's office was on the top floor. After going upstairs, Xu Yiqing met Du Yu.

He stood in the corridor outside the office with a serious expression. In front of him stood a tall and thin man with a look of collapse on his face, as if he wanted to cry but couldn't.

As expected, this was the security guard who first discovered the deceased.

The security guard said, "I swear the key has been in the security room. It has definitely not been lost! And when I came here this morning, the door was locked. It's absolutely true!"

Du Yu frowned even more upon hearing this, and his frown did not ease even when he saw Xu Yiqing.

"Old Xu, things are getting a little tricky."

This sentence is a double entendre. The first meaning is the same as what the mentally ill person who "made a false police report" said, the principal of No. 4 Middle School is really dead.

The second meaning is that this case is also very difficult.

Du Yu said: "Based on the current situation, it was a murder in a closed room."

Xu Yiqing said: "Let me take a look at the scene first."

The office door was open. Xu Yiqing put on foot covers and medical gloves and stood at the door looking inside.

The principal of No. 4 Middle School was lying on his back on the ground, covered in blood. The wound was on his neck, and he was almost killed by a single blow.

Xu Yiqing led Lin Sheng into the room carefully and saw a few eye-catching words written in blood on the wall:

I'm guilty!
The same feeling as Du Yu came to my mind. This was another extremely difficult case.

Xu Yiqing asked Lin Sheng to take photos of the body for evidence, and then checked the house.

The office has a desk, a computer, a wall-mounted air conditioner and a wardrobe.

The computer was not turned on and the air conditioner was off. The deceased was lying in the middle of the room, but the bloodstains were near the closet.

Xu Yiqing observed carefully and found that the wardrobe had double doors and there were splattered bloodstains on the front, but the bloodstains had long since dried up, similar to the bloodstains on the deceased's body.

After observing it, Lin Sheng also said, "This bloodstain has been there for at least ten hours."

Xu Yiqing nodded: "It may take longer."

He reached out and touched the edge of the bloodstain on the surface of the wardrobe, twisted it with two fingers, and determined the viscosity.

Without looking at the livor mortis and rigor mortis on the body, just the drying of the blood at this room temperature is enough to tell that the deceased died at least yesterday.

Then he squatted down and began to examine the deceased's wounds. There were no obvious external injuries, and combined with the traces of blood on the neck, it could be determined that this was an injury sustained before death.

After a person dies, blood circulation stops and the heart no longer provides blood pressure, so there will be no spurting blood when the carotid artery ruptures.

It is almost certain that the wound on the neck is fatal.

"It's a sharp weapon wound." Xu Yiqing murmured to himself after checking: "The wound is deep on the right and shallow on the left, almost a horizontal straight line. The murderer is right-handed, with the blade facing outwards, and cut the victim's neck from right to left."

This overhand grip is very similar to military fighting techniques.

Many people have a misunderstanding about how to hold a dagger, thinking that holding it like a kitchen knife is a forward grip. In fact, it is just the opposite. For a dagger, holding it with the blade facing up is a reverse grip, and holding it with the blade facing down is a forward grip.

Xu Yiqing called Du Yu and demonstrated to him the way the murderer held the knife when he killed the victim.

Du Yu is a retired armed police officer who turned criminal policeman. He is very familiar with the fighting skills within the system. Hearing this, he thought about it carefully.

"If it were me, I would point the blade inwards and stab the victim's neck directly. Damaging the carotid artery from the side would kill the victim more quickly. After all, there are actually four blood vessels in the neck, two arteries and two veins, one moving and one static, forming a group, one on each side of the neck."

"That's what we were taught anyway. And the way you demonstrated, with the blade facing outward, is more like the way foreign soldiers do it, in order to cut the victim's trachea to prevent him from calling for help."

After a brief discussion, the two came to the conclusion that the murderer was no ordinary citizen, but was familiar with killing techniques and was good at mixed martial arts.

The sound of Lin Sheng pressing the shutter button resounded throughout the room, and suddenly he uttered a puzzled "eh"

"Brother Xu, Captain Du, please take a look. Doesn't the bloodstain on the closet look unnatural?"

Hearing this, Xu Yiqing and Du Yu stood up and went to the closet to examine the bloodstains that Lin Sheng mentioned.

Soon Xu Yiqing discovered what was unnatural about what Lin Sheng said.

He pointed to the center seam of the double doors of the closet: "The bloodstains don't match up. The right side is two centimeters higher than the left side."
