"I don't think the security company has a vision." I sat on the couch and said as I enjoyed my breakfast.

Tang Zhenguo frowned, didn't say a word, and nibbled on the steamed bun in his hand.

I gulped the steamed bun in my hand into my stomach, took a sip of water, and said, "You've been like this since you came back yesterday, I guess you're not frustrated because you lost your job as a security guard who only worked a day!" ”

Tang Zhenguo put the steamed buns on the plate, sighed and said: "I originally arranged to do security work in the Xingfuyuan community, but I didn't expect to be recognized by the owner of the community in less than half a day, and the owner complained to the security company, saying that a murderer could not be accepted to come to their community as a security guard." Yes, no one can accept a murderer. Tang Zhenguo tore the steamed bun in half with some anger, and then picked up half of it and took a bite hard.

I handed the water cup in my hand to Tang Zhenguo, and was organizing what language to use to comfort him, when suddenly my mobile phone rang, and it was Lao Lu who called, and it seemed that there was a big case again.

After talking to Lao Lu, I turned to Tang Zhenguo and said, "Haven't you always wanted to know what I do?" Come with me and you'll find out. And it's not far, we're two steps away, so you should go out and relax. ”

Tang Zhenguo was still in his frustration at this time, and it seemed that he accepted my proposal. He nodded, and we put on our coats and locked the door.

Lao Lu just said on the phone that there was a gas poisoning incident at 1709A Beishan Road, and one person died, but Lao Lu felt strange and asked me to go over and take a look.

It was only eight o'clock in the morning, but when we arrived at the scene of the incident, there was already a large crowd of onlookers. I heard from them that it must have been the dragon who appeared and took the life of the stonemason.

Lao Lu was already waiting for me at the place of the incident at this time, and when he saw me, he said bluntly: "The deceased is a male, named Wu Qiguo. The scene of the crime was on the third floor, the scene had been cordoned off, the body had not moved, and the medical examiner said that the time of death was probably between 3 and 4 o'clock in the morning, and the time of death would not have been more than four hours. ”

I frowned and asked, "Did someone report the crime?" ”

Lao Lu said: "Yes, it is a colleague with him, who is also another person with gas poisoning, and has now been transferred to the central hospital for treatment." ”

I nodded, and strode upstairs. At this time, I heard Lao Lu's stern voice: "The police are handling the case, and the idlers and others please do not approach the scene of the crime." ”

I turned around and saw that Lao Lu was looking at Tang Zhenguo, and I quickly explained: "Old classmate, he is not an idle person, he is mine...... Personal bodyguard. ”

As soon as I said this, both of them were shocked. Lao Lu asked, "When did your kid hire a personal bodyguard?" ”

I smiled and said, "You know that my line of work is dangerous, please ask a bodyguard to defend yourself and feel safe." ”

Lao Lu swept my eyes and said, "Your line of work is dangerous? Then I, as a policeman, can't I hire ten or eight bodyguards? ”

"It's a joke, it's a joke!" I hated myself for talking about personal bodyguards and how good my assistant was.

"Let's go up together, and be careful not to destroy the crime scene." Lao Lu's lifting of the ban made me breathe a sigh of relief.

So the three of us strode up to the third floor and came to the scene of the crime.

This is a five-storey building, and this building in this area is very large-scale, and it is a return to the old city that was once renovated. The one we are in is a house facing the mountain, and the environment is secluded.

Room number 302 at the scene of the crime was located in the center of the three houses, with the main door facing the stairwell. I put on my gloves and entered the room first, because Tang Zhenguo added the identity of a bodyguard to him indiscriminately, so Lao Lu didn't let him into the room. However, I looked back at Tang Zhenguo's expression, he did not show dissatisfaction, but his face was full of curiosity, and he also looked in from the door.

Without Lao Lu's guidance, I saw the corpse at a glance in the living room. He is about 1.78 to 1.8 meters tall, lying neatly dressed on the sofa in the living room, his left foot hanging from the sofa, and his cotton slippers are still on his feet. Judging from the age, it should be around 40 years old, the hair is a little greasy, and the stubble on the face should have not been shaved for three days, but the face is also tough, and it belongs to the more handsome type.

Lao Lu pointed to the blanket next to him and said, "When he found the body, he was covered with this blanket, because it was removed during the forensic examination. ”

I nodded and asked, "What is the cause of death?" ”

Lao Lu said: "The preliminary forensic test was that he died of suffocation, and the cause of the suffocation was caused by a natural gas leak. ”

I frowned, and my eyes fell on the messy coffee table in front of the couch, on which were a few plates of leftover braised vegetables, a plate of peanuts, and two disposable plastic empty wine glasses, but strangely there were no bottles in sight.

"Where's the bottle?" I walked to the coffee table and turned around but didn't see it, so I asked Lao Lu.

Lao Lu also felt strange, so he also looked around and looked in the trash can, but there was still nothing.

"There's something wrong with this bottle!" As I spoke, I picked up the wine glass on the coffee table and brought it to my nose and sniffed it.

"It smells like a strong wine, it's not ordinary wine, it's a spirit." I handed the wine glass to Lao Lu and said, "Take it back and check the remaining wine stains to see what kind of wine it is, and whether there are any other pharmaceutical ingredients that cause people to be unconscious." ”

Lao Lu put both wine glasses into the evidence bag and said, "You mean that someone put medicine in the wine to make the deceased unconscious, and then suffocated him to death through natural gas?" ”

As I walked towards the kitchen, I said, "It's possible, but you said that there was another victim, who also drank alcohol and inhaled gas, but why did he come back to life, I don't think it could be such a simple reason that the man's physical fitness was better than that of the deceased." ”

As soon as I finished speaking, I suddenly heard Tang Zhenguo outside the door shouting: "Ouyang, there is an old woman who said that she knows who killed this person." ”

When Lao Lu and I heard this, we looked at each other. Hurriedly walked out the door.

Outside the door, a white-haired woman about 70 years old poked her head out from behind the half-covered door of room 301.

Lao Lu saw the old woman's nervousness, so he said with a smile: "Old man, don't be afraid, the people's police are not tigers, we are protecting the people." You know what, just say it. ”

The old woman seemed to relax a lot after listening to Lao Lu's words, so she opened the door completely, glanced at the three of us, and then took a few steps closer, and said mysteriously: "This Wu stonemason was killed by Qinglong. ”

When Lao Lu heard this, he squeaked with disdain, and then said: "Old woman, we are handling the case, don't make trouble for us." ”

When the old woman heard this, her face turned red, and she raised her voice and said, "It's true, I didn't lie to you. ”

Lao Lu was about to refute, but I hurriedly patted him on the shoulder, and took a step forward and asked, "Old woman, then what basis do you have to say that this Wu stonemason was killed by Qinglong?" ”

The old woman said matter-of-factly: "We have a saying here since ancient times, the white tiger is ten thousand feet tall, and the green dragon looks up. This Qinglongyan is an immortal from the sky, and he has always guarded the peace of this side. More than ten years ago, the government wanted to destroy Qinglongyan to build a road, and it was because the stonemason who hit Qinglongyan died for unknown reasons before the construction started, so it gave up. In recent years, Qinglongyan has been worshiped by the locals, and the incense is also very prosperous. But I don't know why, the government is coming to knock out Qinglongyan again. I heard others say that this Qinglong Rock stands in the middle of the road, which not only affects traffic, but has also become a superstitious thing. I think superstition is a thing, sometimes, I really have to believe it. You see, this Wu stonemason has only been fighting Qinglong Rock for a day or two, and he died inexplicably, so what else could it be if Qinglong didn't take his life? ”

Lao Lu was too lazy to listen to the old woman's nonsense, and had already returned to the scene of the crime. Tang Zhenguo and I listened very hard, and when the old woman finished speaking, I said: "Old woman, thank you for the clues, we will consider this situation carefully." ”

"What else to consider? It must be so. The old woman said very resolutely.

I smiled and nodded, thanked the old woman again, and walked back to the crime scene, leaving Tang Zhenguo alone outside. I didn't expect him and the old woman to be eagerly talking about something, but I didn't have time to listen to what was said.

I came to the kitchen, and Lao Lu was already inside at this time, and he complained, saying that I was wasting time listening to the old woman's nonsense, and I said that it was not a bad thing to listen to the opinions of the masses.

Lao Lu rolled his eyes and pointed to the gas stove. I looked around the environment of the kitchen, and also focused on the gas stove pointed out by Lao Lu, this gas stove is a double stove, and the stove on the left obviously has a lot of stagnant water, on the surface, it is the gas leakage from this gas stove that suffocates Wu stonemasons to death. But this is also where Lao Lu feels strange.

The kitchen is indeed connected to the living room, just one door away, but the kitchen window is open. I tried the window, but it was already rusted, so I couldn't close it. Perhaps because there was a screen window outside, the owner of the room had never repaired the oil-stained window. And it is common sense for the kitchen to open the window for ventilation, so it is normal for this window to be open. But what is not normal is that the windows are open, why does Wu Mason still suffocate to death?

I examined the window carefully and saw that some grease stains had been wiped off the edge of the window, apparently someone had tried to close the window without success. Seeing this, I think Lao Lu's suspicions are reasonable, this murder is by no means as simple as an accident.

I checked the gas stove again and found that it was an old-fashioned gas stove that continued to supply gas after the flame was extinguished by water, which proves that the gas is likely leaking from the wet stove hole. However, this is at odds with the open window, and I'm locked up in a mystery at this point.

"Ouyang, how is it? You think it's strange too! Lao Lu leaned against the kitchen door with his hands on his chest and said.

I frowned, pursed my lips and nodded slightly, and stood up straight in the middle of the kitchen. Looking around the whole kitchen again, this kitchen is only six to seven square meters, cupboards, disinfection cabinets, range hoods, gas stoves, pools, water tanks, these ordinary things in the kitchen are like problems that fascinate my heart.

At this time, I shifted my eyes to the gas stove with water stains, and then asked Lao Lu: "How are these water stains formed?" ”

Lao Lu pointed to the boiling kettle on the ground and said, "This kettle was placed on the stove when I came, and I moved it away when I checked the gas stove, it should have been splashed after the water in this kettle was boiled." ”

As soon as I heard this, I hurriedly rushed out of the kitchen to the living room and went straight to the water dispenser in the living room. There is still more than half a bucket of water in the water dispenser, and the heating function of the water dispenser is not damaged. If you want to drink water, there is obviously no need to boil water.

I ran back to the kitchen, filled the kettle with a full jar of water, and set the kettle on the stove on the right to heat it up.

Lao Lu saw it and asked, "Do you want to test how much water is splashed to make this gas stove go out?" ”

I said, "Yes." The kettle is an old-fashioned aluminium kettle, and I don't think it will spill more water than the amount of water on the gas stove on the left when it's full. We'll see. ”

Ten minutes later, a full pot of water boiled. Hot water overflowed from the lid of the kettle, and after listening only to the sound of snorting, the gas stove was extinguished, and the gas supply was still there, making a whirring sound of natural gas.

I turned off the gas switch, found a handkerchief from the kitchen, and carried the kettle away through the handle of the kettle.

Sure enough, the amount of water on the right gas stove is far less than that on the left.

"Obviously, the extinguishing of the flame of the gas stove at the time of the crime was not doused by the boiling water overflowing from the kettle, but deliberately extinguished." I'm sure of that. Then he picked up the stainless steel scoop next to the stove and continued: "The murderer should have used this scoop to hold water, then extinguished the burning gas stove, and then put the kettle on the leaky gas stove to cover people's eyes." ”

Lao Lu also nodded and said, "Your analysis is very reasonable, it seems that this is indeed a homicide case." ”

I looked at Lao Lu and said, "But I'm still very confused, because the kitchen window is open, so the leaking natural gas is obviously not suffocating." Are you sure that the deceased was suffocated by natural gas? ”

Lao Lu said with certainty: "The forensic doctor has preliminarily identified that it was suffocation, and it will never be suffocation under external force, I was the first to rush to the scene of the crime, and when I entered the house, I also smelled a strong smell of natural gas." So the deceased died of natural gas suffocation, no doubt. ”

"That's weird!" I frowned and sighed.
