"Captain, be careful, the gas inside hasn't been cleared yet." A police officer reminded.

Liu Xiangshan ignored it and walked straight to the house.

This is a small room of less than ten square meters, and it is very messy, and there are bottles and cans piled up everywhere in the corner, probably picked up. The furnishings in the room were also extremely rudimentary, except for a broken table and a chair that creaked at the touch of a beat, and a tattered bed.

A little boy with messy hair and tattered clothes was lying on the bed with his eyes closed.

Maybe a few hours ago, he was a living being, a pitiful life, but now he is a corpse without temperature.

No one knows what kind of experience he had, but what is certain is that it must be full of bitterness and difficulty.

Twenty minutes later, the medical examiner came, and after a preliminary examination, it was determined that it was gas poisoning. After fingerprints were taken, the body was taken back to the police station for further autopsy.

At this moment, the murder hut had already set up a cordon, and it was surrounded by people watching the excitement, and there was no expression on their faces except indifference.

"Hmph, there is no shortage of people to watch the excitement at any time!" Liu Xiangshan thought to himself and looked at these people with disdain.

At this time, Xiao Zhang walked in quickly and whispered: "Captain, ask clearly, the deceased is Xiao Xiang, he has been an orphan since he was a child, and he has no relatives ......."

Liu Xiangshan nodded, continued to look around the room, and stayed on the table next to the window, followed by the window sill above, the window.

He took a few steps forward, came to the window, stretched out his hand and grabbed the handle of the window, and twisted it vigorously, making a "creaking" sound, and it was actually able to open. Although it doesn't seem to be open often, you can still see the signs of opening.

"How did he get here without relatives?" Liu Xiangshan asked casually.

"I've inquired, this was originally the residence of an old man who lived alone, since the old man died a few years ago, no one has taken care of it here, and then Xiaoxiang moved in."

There are more and more people watching the excitement outside, and the noise is getting louder.

"Orphans, living alone......"

Liu Xiangshan was pondering, and was a little upset by the noise, so he said loudly: "Put the people who are watching the excitement outside....... Dissuaded! ”

He couldn't help but say the word "撵".

Xiao Zhang knew that Liu Xiangshan didn't like others to disturb him the most when he was thinking about the case, so he hurriedly ran out, and then the sound of "disperse" came.

Liu Xiangshan looked at the ground carefully, and there were no second pair of footprints, but he saw a few less obvious scratches next to the table legs, proving that the table had been moved.

He gently pushed the table to the edge of the scratch, right below the window.

"Someone moved the table to this position." He pondered in his heart.

Then he noticed something suspicious.

The whole chair was covered with dust, indicating that no one had sat on it for a long time. However, the dust on the table was much less, most notably of varying thickness, as if it had been wiped locally.

Then he walked to the "kitchen", which was actually a broken gas hood, a broken pot on the stove, and a bowl with a missing mouth and dust.

"Xiao Xiang won't lie on the table to eat." Liu Xiangshan thought.

Liu Xiangshan walked to the table again, lowered his head and searched carefully, but still found no footprints.

Hasn't a second person ever come in?

So why was the table moved?

Could it be that Xiao Xiang found a gas leak and wanted to climb out of the window?

No, it doesn't make sense......

On the way back to the police station, Liu Xiangshan kept thinking, thinking about Xiaoxiang's death, and then thinking about Wang Zhongliang's mysterious disappearance, as well as Ye Guangli's death.

Although the modus operandi of these three cases is different, they all have one thing in common, that is, there is no second person at the scene of the crime.

"Murder in a closed room?" The most mysterious modus operandi in the detective world once again poured into Liu Xiangshan's head.

……

Soon, the autopsy report came out, and the deceased had no external injuries before his death, and there were no signs of a fight with people, which could be determined to be gas poisoning. And it is certain that the time of death was two days ago.

"Could it really be an accidental death caused by a gas leak?"

Liu Xiangshan always felt that he had missed something, and recalled the scene at the scene of the crime.

"No, judging from the degree of dust in the kitchen, Xiao Xiang doesn't cook, and besides, he can't pay the gas bill, how can it leak without gas?"

He seemed to have something in mind.

"Xiao Zhang, arrange for someone to go to the gas company to check when the gas in Xiaoxiang's house was turned on!" With that, he hurried out, and then the sound of a car starting.

When he came to the slum again and saw the lifeless dilapidated houses and neighborhoods, Liu Xiangshan's mood was still heavy.

He walked straight into the room where the crime occurred and looked around, trying to find the details that had been missed last time. After a search, the most suspicious thing was the table.

Suppose there is a second person present at the scene, and this person is the murderer, and after committing the crime, he moves the table under the window, steps on it, climbs through the window and leaves. However, the question arises: how did the table get to its original position?

Could it be that Xiao Xiang moved it himself?

Liu Xiangshan could almost conclude that the murderer escaped from the window, or left calmly. There may be an unknown factor in why the table was moved and the footprints on it were erased.

There is also a doubt, that is, why there are no footprints of the murderer on the ground?

"It seems that these doubts will not be solved for a while, and I hope that there will be progress on the gas company's side." Liu Xiangshan thought helplessly.

After thinking for a moment, he decided to go back to the bureau first.

Just as he was about to get into the car, he inadvertently turned around and found a small head on the corner across the street, staring straight at him!

Liu Xiangshan subconsciously looked back again, the little head flashed and disappeared, and he didn't have time to think about it, so he chased after him.

The environment in the slum is very poor, all of them are densely packed with dilapidated small houses, and there are many small forks in the road, twisting and turning, and each path is connected to each other, like a labyrinth.

Liu Xiangshan was not familiar with the path, and chased after him very hard, and almost caught him several times, but he ran away from the small alley.

However, from his back, it can be seen that this is a fifteen or sixteen-year-old child, although he was born thin, he is quite agile when running.

The child did not dare to run out of the slum, but only circled around, and after a long time, his physical strength gradually decreased, and the more he ran, the slower he became. In the end, he was held down by Liu Xiangshan at the corner of an intersection.

"What's your name, what the hell are you doing!" Liu Xiangshan asked with a gasp of temperament.

The child may have been frightened and didn't say a word, but his eyes were rolling and he looked very smart.

At this time, Liu Xiangshan looked around, and several people were already slowly surrounding, obviously with bad intentions. He picked up the child and walked briskly towards the police car, which did not stop until they saw it.
