Debt disputes are indeed the motive for many homicides, and this case is very likely to be caused by debt disputes.

However, according to the clues we have, the technical team did not find the fingerprints and footprints of other people in the single house, except for the footprints of the seven deceased, only one 36-yard footprint wearing slippers.

If it was really Shan Bao who chose to kill the door and retaliate because Shan Xuan borrowed money and did not repay it, then why did no footprints of Shan Bao be found at the scene? And whose footprint is this 36-yard footprint?

The most critical thing is that Ren Qiushi of the forensic department passed the autopsy and came to the conclusion that the murderer had the greatest hatred with the eleven-year-old Shan Jinfeng, and Shan Jinfeng and Li Meng's criminal profiles were of similar age.

Perhaps, we should still look for clues from Shan Jinfeng.

The matter of investigating the single report was handed over to Lin Zifan and Xue Hang, and Li Meng and I were going to go to Shan Jinfeng's school to have a look.

Today is the first day of the Lunar New Year, the school gate is locked, and the Spring Festival couplets are pasted, and it is already a holiday. There was no one in the entire school, and there was no officer on duty in the police room at the entrance.

However, we have investigated the detailed personal information of Shan Jinfeng through the internal system of the Public Security Bureau, he is studying in the second class of the sixth grade of the No. 1 Experimental Primary School in Ningzhou City, and the head teacher is a female teacher named Yin Meng.

Yin Meng's family lives in Ningzhou City, and the household registration department provided us with Yin Meng's home address.

It is not uncommon to go out on the first day of the Lunar New Year to visit relatives and friends, but it is very strange that the people who visit the door are empty-handed and do not take any gifts.

Moreover, these two people are also criminal policemen.

Yin Meng's home is still relatively easy to find, her family lives in a community in the eastern district of Ningzhou City, which is a fifteen-minute walk from Ningzhou No. 1 Experimental Primary School.

The neighborhood is littered with debris from firecrackers, and the air smells faintly of fireworks.

When I came to Yin Meng's door, I raised my hand and knocked on the door.

"Who?"

After about ten seconds, a woman's voice came from the room.

"Is it Teacher Yin Meng's house?" I cleared my throat and spoke to the woman in the room through the security door.

In the next second, the door opened directly, and Yin Meng didn't even confirm whether the people outside recognized him, so he opened the door very enthusiastically, and at the same time sent us an invitation to enter the house and sit down: "Please come in, two of you." ”

Li Meng and I glanced at each other, and we both had an inexplicable feeling, dare to love that the primary school teachers are so hospitable now?

Li Meng and I looked at the woman in front of us for some reason, she looked like she was in her thirties and had a professional smile on her face. This smile, while not a smirk, is not sincere either.

She looks relatively beautiful, especially those eyes, which are extremely attentive and seem to be full of innocence. Maybe it's because she is a primary school teacher, and after long-term contact with elementary school students, she will naturally change her personality.

Yin Meng didn't ask us who we were, or even what we were doing this time, but very enthusiastically took us to the sofa in the living room and sat down.

This feeling made Li Meng and I forget what we were here for a while, and thought it was a normal visit to relatives and friends.

Sitting on the sofa, Yin Meng's face continued to have an insincere smirk, we looked at each other, no one spoke, and it was very embarrassing for a while.

But after all, we are a professional criminal policeman, and we will identify ourselves when we are undecided.

Thinking of this, I settled down and reached into my pocket to get my police ID.

"Oh, don't be so polite, just come, what else do you bring?"

Seeing my action of reaching out for something, Yin Meng hurriedly said the lines he had prepared a long time ago, as if he was conditioned.

Her words directly reminded me of the picture of my relatives visiting the door when I was a child.

If she can still say: "This is for children, not for you", then the picture sense is even more sufficient.

"And bring things, this is too out-of-the-box." Yin Meng continued to speak.

For a while, I had already picked up the police ID in my pocket, but I didn't take it out, and I didn't continue to put it in my pocket, so I was in a dilemma.

Li Meng beside him was even more embarrassed, the corners of his mouth twitched slightly uncontrollably, and he looked at me very embarrassed, and then at Yin Meng.

Yin Meng was also very embarrassed at this time, she seemed to find that her polite words were a little early.

The corners of her mouth twitched slightly, and she looked at me very embarrassed, and then at Li Meng.

For a moment, the atmosphere in the living room was extremely awkward, and all three of us looked at each other with a smirk and a very embarrassed heart.

The only way to resolve the embarrassment now is that I naturally took out a gift from my pocket and handed it to Yin Meng.

But we didn't come to visit the house, and we didn't bring any gifts, and I only had a police ID in my pocket.

The air froze for about a minute, and Yin Meng was the first to speak to break the awkward situation.

She said slowly, "Haven't you asked which student's parents are yet?" ”

At this moment, Li Meng and I finally understood why the elementary school teacher named Yin Meng in front of us would be so enthusiastic and invited us into the house so enthusiastically without asking for a clear identity. It also explained very well what she had just said in advance, she probably regarded us as the parents of a student in the class, and the parents came to visit the teacher on the first day of the new year, so they naturally came to give gifts.

Looking at Yin Meng's expectant eyes, I can no longer feel the original innocence.

In the next second, the hand that had already grabbed the police ID in my pocket slowly let go, and then showed a more far-fetched smile and said, "Oh, we are Shan Jinfeng's parents." ”

"Oh-it turned out to be Shan Jinfeng's parents, you are his ......" Yin Meng let out a voice of sudden realization, and finally asked tentatively.

With Li Meng and I being less than thirty years old, it is a bit far-fetched to say that Shan Jinfeng's parents are a bit far-fetched, and Yin Meng has taught Shan Jinfeng for six years, even through regular parent-teacher meetings, he must have met his parents.

"We are Shan Jinfeng's brother and sister-in-law." I settled down and said lightly, while looking at Li Meng very naturally.

Li Meng was also very cooperative, nodded again and again, and replied, "Hmm...... Well, right. ”

After hearing this affirmative reply, Yin Meng's eyes carefully looked us up and down, and saw that we all came empty-handed, especially when we saw that we had just taken out our pockets and didn't take anything in our hands, a trace of displeasure immediately appeared on our faces.

"Is there something wrong with the two of you?" Yin Meng's attitude has changed significantly, and he seems to be dissatisfied with our behavior of coming empty-handed.
