Xue Hang had already judged that the murderer's entry and exit routes were all through the courtyard gate according to the surrounding environment at the scene.

The murderer entered through the courtyard gate openly, and walked out of the courtyard gate openly after the killing, which is really arrogant.

"Was the murder weapon found at the scene?" I looked into the room and asked slowly.

Xiao Ligong shook his head and said helplessly: "I didn't find anything, the kitchen knife used by the murderer to kill people, the brick that hit Chen Xuechun's head hard, and even the mop cloth that the murderer used to clean up the scene were not found." ”

"It's understandable that the murder weapon was taken away, even the mop was taken away?!" Lin Zifan asked in surprise.

"Kitchen knives and bricks are very easy to carry, and the mop is not one meter five but one meter two, where will he take such a big thing?" I'm also thinking seriously about this question, after the murderer kills, it is very common to clean up the crime scene and take away the murder weapon, but he actually took the mop away.

"It must have been taken to a distant place and abandoned or buried." Xiao Ligong put forward his own speculation.

"Perhaps, there is a better place." Jiang Tingbai looked at us and said with a serious face.

"Where?!" All of us set our eyes on Jiang Tingbai, waiting for Jiang Tingbai to say his answer.

Jiang Tingbai faced the gaze of all of us, and suddenly felt a little embarrassed.

This is the first time we have seen this kind of expression, and at the same time, it also makes us feel more curious.

"If it were me, I'd throw the murder weapon into the toilet pit." Jiang Tingbai said slowly.

After listening to him, we hurriedly walked together towards the toilet on the east side of the courtyard.

Due to environmental factors in rural areas, most of the toilets in rural areas are not washing toilets but earthen toilets.

The so-called earthen toilet is to dig a deep pit of three to five meters or even deeper in the ground, and then build a toilet on top of the deep pit.

In some remote villages, there are even more rudimentary earthen latrines, that is, a high platform is erected above the ground and then toileted. When the excrement is full, use tools to remove the excrement from the burial. It's not something that pollutes the environment, but buries the waste in the ground, which becomes a kind of fertilizer.

In the courtyard of Tao Yunshu's house, there is a seepage well-type toilet, which exudes a foul smell, which is bearable for us, but for Jiang Tingbai, a physique who is particularly sensitive to smells, it is simply a nightmare. The stench we smell is amplified hundreds or thousands of times by him.

Jiang Tingbai wore a mask, subconsciously held his breath, turned on the flashlight and shone at the five-meter-deep dung pit, which was full of excrement and toilet paper, and no murder weapon was found.

Jiang Tingbai frowned, turned around and walked out of the toilet, and while taking a breath, he picked up half of the bricks.

He returned to the toilet and threw half of the brick into the manure pit, only to hear a muffled sound and the brick fell steadily.

"What are you doing here?" Lin Zifan asked him very puzzled.

Jiang Tingbai didn't speak, maybe he was observing, maybe he was holding his breath, he observed for about two minutes, and then walked out of the toilet quickly and explained to us the reason why he did this: "The bricks have no tendency to sink, which shows that if the murderer threw the murder weapon into the dung pit, the murder weapon will not sink with the passage of time." ”

"So the murderer didn't throw the murder weapon into the toilet, but took it away?" Lin Zifan asked seriously.

Jiang Tingbai pondered for a moment, nodded slowly, and said, "This is indeed the case. ”

After the on-site investigation, we have a relatively comprehensive and detailed understanding of this case.

We are ready to leave the scene of the crime and officially enter the investigation and visit stage of the investigation of the case.

Just as we were about to leave, I suddenly saw Li Meng standing in the position of the barn, constantly looking around.

Only then did I react, during the entire on-site investigation, Li Meng didn't say a word, just silently followed behind us, constantly observing and thinking about something.

I walked slowly to Li Meng's side, not wanting to disturb her thoughts, but she still spotted me.

"Did you think of something?" I asked softly.

Li Meng looked at me in a daze, frowned slightly, and said slowly: "I think the nature of the case is not only a vendetta. ”

Her words surprised me very much, because the murder case is basically a vendetta that can be determined. After all, if there is no deep hatred, who will kill a family? And even the eight-year-old did not let go.

Li Meng pondered for a moment, and suddenly said to me: "I think it may be a love killing." ”

"Love killing?!" His conclusion can be said to shock me very much, although there are few cases of murder caused by love, but it cannot be completely said that there are none.

It's just that I'm more curious, what clues did she use to think that this case was a love killing?

Li Meng looked at me seriously and said what she thought: "The autopsy report shows that the three deceased did not have restraint injuries and resistance injuries on their bodies, which shows that the murderer did not fight with the three deceased, or that the murderer committed the murder when the three deceased were defenseless. The time of the crime was around one o'clock in the second half of the night, and the female deceased, Chen Xuechun, came out to go to the toilet alone, and if she saw the deceased at this time, she should have immediately screamed, but she did not.

Therefore, it is extremely likely that acquaintances will commit crimes. Moreover, the toilet is on the east side, and the first crime scene in the barn is on the west side. Chen Xuechun would never come out of the toilet and go back to the room to sleep without being threatened or guided, but going to the warehouse on the west side.

From this, it can be inferred that Chen Xuechun saw an acquaintance at that time.

If they were acquaintances, they could just stand in the courtyard and talk normally, so why did they go into the barn on the west side? And have you noticed that Chen Xuechun and her husband Tao Yunshu's room is in the bedroom on the east side, and the warehouse is exactly in the opposite direction. Is it possible that Chen Xuechun and the murderer chose to meet in the warehouse on the west side in order to deliberately avoid her and her husband's east bedroom? ”

I listened to her words and fell into complete contemplation.

Li Meng's unique perspective very reasonably explains the situation in the warehouse on the west side that is the scene of the first crime. The forensic autopsy said that Chen Xuechun did not have any restraint injuries or resistance injuries on his body, so it was impossible for the killer to take Chen Xuechun to the warehouse on the west side by violent means.

Moreover, there were no traces of blood in the yard, which basically ruled out the possibility that the murderer first injured Chen Xuechun with a brick, and then took her to the warehouse on the west side to kill her.

Love murder does provide a new idea for this case......
