The case occurred in Anyong Village, Qingquan County, Xiling City.

We didn't know what the case was. After Jiang Bing received the message, he packed his luggage and rushed towards the location of the case.

I know that Xiling City is adjacent to our Xishan City, and there is not too far apart between the two places. However, I am now in the provincial capital and am a little bit away from here to Xiling City.

Xiling City is much larger than Xishan City. Although it is larger, Xiling City is not as prosperous as Xishan City. Because Xiling City is surrounded by mountains, the center of the city is located in a vast land among several mountains. Moreover, I once heard that there was an earthquake in Xiling City decades ago, and that earthquake accidentally triggered mudslides on the mountain.

The city of Xiling City is between several mountains. Not long after the mudslides flowed out, some areas of Xiling City were flooded. It is said that the natural disaster was missing and many people were injured.

I don't know what tricky cases will be in a place like that.

The only ones who went to that place were Zhao Jiyou and Jiang Bing, and Mao Zhengyuan did not come with me. According to Jiang Bing, that is, Mao Zhengyuan is now in retirement stage. The reason why he stayed in the Dragon Bureau may be because he did so much for the Dragon Bureau in the end not only did not get better, but also had a strange disease, which was considered as compensation from the Dragon Bureau to Mao Zhengyuan.

Mao Zhengyuan has his own thinking, and the Dragon Bureau did not have any actions to restrain Mao Zhengyuan. He could run away at will. In previous case investigations, Jiang Bing and Zhao Jiyou took over, and Mao Zhengyuan would not follow him. This time it was still the case.

It was the third day when we arrived in Qingquan County. Several of us came to Qingquan County in the name of "experts". The small county town was not like the city. Some of them may not have seen an expert in half their lives, so someone came to pick us up just after we arrived in Qingquan County.

The police officer who was in contact with us was Wen Rong. He was about thirties and wore a pair of black-framed glasses. He always had a smile on his face and looked like a very kind person.

But when he saw the third place, the smile on his face froze slightly, showing a bad look. I guess he didn't expect that the experts who came down from the big city would be so young.

After being slightly surprised, Wenrong saw that we had been tired for a few days and was a little disappointed, so he planned to arrange us to rest in the hotel for a night and wait until tomorrow to explain the case to us in detail.

Jiang Bing waved his hand and rejected Wen Rong's kindness, saying that since the matter was so bad that we asked us to come, don't delay the time and figure out the case as soon as possible.

"The case... is bad but not very bad." Wen Rong sighed in embarrassment and said, "Let's go to the police station first. After arriving at the police station, I will repeat the case in detail to you."

I don't understand what Wenrong said is not bad, but I didn't say much about it. I got into the car that Wenrong drove towards their police station.

The police station went through a thousand words, and the Qingquan County police station was only smaller than the city. There was no difference. After arriving at the police station, Wenrong took us to a conference room, and then he introduced himself to us.

Wen Rong is the captain of the Criminal Police Team in Qingquan County Police Force, and he is mainly responsible for this case. He is the one who knows the development and process of the case best.

After the two parties briefly introduced themselves, Wenrong's expression became heavier.

"The case happened in Anyong Village below our Qingquan County. Anyong Village is more than an hour's drive from Qingquan County, mainly because the mountain road is not easy to walk. Anyong Village is located in a mountain nest with a simple rural style. Even people who steal chickens and dogs have never appeared. I just don't know what happened this time..."

"What does it mean that the case is not bad?" I asked with a frown.

Wen Rong pondered for a while and said in a dilemma: "It's not very bad, it's just... it's just that this case is a bit strange."

"What's weird?" Zhao Jiyou was more energetic than others when he heard the word "weird". He straightened his back and stared at Wen Rong.

Wen Rong looked hesitant, looking like "should you say it?"

Jiang Bing saw it coldly and naturally told Wen Rong: "You just say anything you have. We come mainly to investigate the case. So we don't want to hear you have any concealment."

Of course, Wen Rong was not capable of becoming the captain of the criminal police team. He also understood this simple rule, but he was still a little hesitant. This also told me in disguise that this case was really strange.

After pausing for nearly a minute, Wen Rong sighed and told us: "This case is not very bad, but a bit strange. The case happened at a small hill in front of An Yong Village, with a newly built primary school on the hill. It was built in the first two years ago, mainly because the nearby children had no place to go to school, so the leader applied to the superior for approval."

"The victims are two men and two women, and they are...all in-service teachers in the school."

Wen Rong finally mentioned the key point of the case. I think the main reason lies in these four teachers.

"How did these four teachers die?" I asked casually after taking a sip of water.

Wen Rong took a deep breath and replied: "It should be... suicide."

"It should be suicide?" I was slightly stunned, put down the water cup and looked at Wen Rong in confusion: "Have all the autopsies of these four deceased people been performed?"

Wen Rong nodded and said, "The forensic doctor in our county has performed an autopsy on the bodies of these four teachers, and no other wounds were found on their bodies."

"How did the four teachers die? And... what can confirm that these four teachers committed suicide?" Jiang Bing looked at Wen Rong in confusion.

Wen Rong said: "The four teachers died of gas poisoning. After we received the report, we found that the four teachers had died in the classroom. After our on-site investigation, we found that the doors and windows in the classroom were locked, and the doors and windows were locked from the inside. So no one would enter from the outside at all."

"Have you done fingerprint retrieval?" Jiang Bing continued to ask.

Wen Rong answered us truthfully: "The people from the identification department have retrieved the fingerprints that appeared in the classroom and collected two sets of fingerprints on the gas tank. We compared the fingerprints of the four deceased and found that the two sets of fingerprints on the gas tank are two male deceased among the four deceased."

"Since the deceased committed suicide, why do you still have to come to us?" Zhao Jiyou looked at Wen Rong in confusion.

Wenrong rubbed his hands in a tangled way and didn't know how to answer.

I took out the cigarette from my pocket and gave it to Zhao Jiyou and Wenrong and lit another one myself: "No matter what you know, just tell us anything related to the case."

Wenrong took the cigarette but did not smoke it, but gently placed it aside.

The embarrassment on his face became heavier and worse. We three did not urge Wen Rong to say it quickly, but waited calmly for him to speak.

After nearly a minute, Wenrong finally gritted his teeth and said.

"The forensic doctor in our county believes that the death of the deceased was around 11:50 p.m. on July 20. But... but someone has seen it at 1 a.m. on July 21 and has seen four deceased!"

"What?!"

We were shocked and incredibly shocked, staring at Wen Rong.

The first thought that appeared in my mind was the word "living zombie", followed by the word "tianxing".

I think I must be more than me, just like what I thought. I looked at Zhao Jiyou and Jiang Bing, and their expressions became different.

"Can this matter be confirmed?" Jiang Bing sat up straight again and asked in a deep voice after calming down.

Wen Rong nodded firmly and said, "I saw that the four of them were old police officers who retired from our county town. Their family lived in EYong Village. After he retired, he returned to EYong Village and started to work as an escort in EYong Village. He had been working for nearly two years. He would patrol the neighborhood of EYong Village at around 12 o'clock every night, and he never stopped for two years. That was at that time he saw the four teachers."

"Who is the person who called the police?" I asked with a frown.

Wen Rong replied to me: "The old policeman who called the police also told us that he saw four teachers going to school from afar. Because the four teachers came to the countryside to teach in the county town. And not long after he arrived, the old policeman was afraid that the four teachers would steal the school things and quietly followed him to take a look. But after waiting to arrive at the school, he found that the four teachers had disappeared for no reason.

After the incident, he told us that he had not noticed the teacher and he started walking around the school casually. When he was waiting to walk to the second floor, he suddenly found that there was light in a certain room. When he arrived at the scene, he found that four teachers were dead. After all, he was also a police officer in our police station and had a lot of common sense. After discovering something happened, he called the police. He waited for us to arrive at the scene before opening the door of the room..."

We looked at each other in three ways, and finally I asked, "Are the bodies of the four teachers still there?"

"Here!" Wenrong answered me without hesitation: "Because we were not sure whether it was a killing or suicide, we were not in a hurry to notify our family to collect the body, and the body was still stored in the police station."

I looked happy and said hurriedly: "I am a forensic doctor and want to see the dead body."

Wenrong must believe our words, and without doubting our words, he took us to the funeral home in their county town.

This kind of corpse is not suitable for storage in the police station. In order to prevent the corpse from smelling and deteriorating, the corpse will be stored in the funeral home.

It was already seven o'clock in the evening when we arrived at the funeral home. Wenrong insisted on letting the people from the funeral home open the door and walked in.

When I turned on the lights in the room, I saw the corpse cabinet at a glance.

After learning the numbers of the four deceased from Wenrong, I found the corpse cabinet of the four deceased with ease, and then pulled it open.

Jiang Bing and Zhao Jiyou helped me put the bodies of the four deceased on the dissection table one by one.

I put on my gloves and glanced at the bodies of the four dead.

The four deceased were two men and two women, both around 26 or 27 years old. They should be all students who have graduated from college.

The two men looked ordinary, but in comparison, the two women looked a bit pretty and beautiful.

We don’t understand why the four good teachers suddenly closed themselves in a gas-filled room and chose this way to commit suicide.

The most important problem is.

What are their motives for suicide?

Everything has cause and effect, and solving cases requires motivation. We have no clues about all of this.

The four deceased had sutured interfaces on the chest cavity, which should be the wounds that were sutured after the autopsy of the forensic doctor in their county.

With these, it was much easier for me. I picked up a scalpel casually to break the lines at the edge of the knife and then quietly observed it.

Gas is called carbon monoxide.

Gas is toxic and can cause people to suffocate and die.

The density of carbon monoxide determines the time of death. The more it is, the faster the death rate is. On the contrary, the weaker the concentration, the slower the death time will be.

The lungs of the four deceased showed blackness, which was caused by excessive breathing of carbon monoxide that caused the red blood cells to lose their oxygen transport function.

Confirmation that the four corpses were like this will only make me sew the four corpses again, and then I began to investigate the appearance of the four corpses.

The four deceased had rosy complexion and cherry lips, which was typical of gas poisoning.

I picked up a scalpel and gently cut the subcutaneous tissue of the body. After I scratched it, I gently pressed it and found that the skin of the four deceased was also softer.

The stiffness of the surface is caused by the air conditioning in the corpse cabinet.

After confirming all this, I took off my gloves and let out a breath and said to Jiang Bing and Zhao Jiyou with a serious expression.

"There are no other wounds in the four bodies. The lungs of the four bodies are darker and rosy in complexion, and the lips seem to be cherries. It is typical of gas poisoning symptoms. Since several bodies have been treated and stored for a little longer, the death time may be somewhat different if we judge it. I want to wait until tomorrow to communicate with the forensic doctor in their county to check the death time."

Wen Rong wanted to treat us to a meal after leaving the funeral home, but Jiang Bing refused.

Jiang Bing asked Wenrong to take us directly to the hotel, and asked Wenrong to help us take all the useful evidence found at the crime site for us to study.

Wenrong nodded in his request to us and did what we said.

After arriving at the hotel, we ate something simple at the barbecue stall downstairs and went to the room to wait for Wenrong.

At about nine o'clock, Wenrong drove over to hand over all the things related to the four teachers to us.

Three of us started a carpet-style exploration in the hotel room.

There were not many things found on the scene, and a carton was filled.

"What is this?"

I took out a large white paper in a sealed bag and asked in confusion.

There is a big circle on the white paper, and there are many words written on it.

Jiang Bing and Zhao Jiyou looked back at the things in my hand together, and finally started shouting in unison.

"Dianxian!"
Chapter completed!
