"As far as the information investigated last night is concerned, he has nothing to do with Yang Hongguang. ”

Officer Sun denied Lu Dongye's conjecture.

I'm really wondering about this winter night...... It wasn't sent by Yang Hongguang to mess up, so who could it be?

"However, last night, we had a colleague go to investigate further, we will go to the communication company to investigate who he has contacted recently, and of course, we will also go to the martial arts school to investigate his interpersonal relationships and so on. ”

Officer Sun spoke again: "The specific results are estimated to come out in the afternoon, and I will contact Principal Lu at that time." ”

"Okay, thank you Officer Sun. ”

Hanging up the phone, Lu Dongye felt a little more relaxed.

If it has nothing to do with Yang Hongguang, it can really save a lot of heart.

At least it can be explained that Yang Hongguang is now under the supervision of the police, and he really doesn't dare to mess around, and he doesn't have that much courage!!

But in this way, Lu Dongye is really strange.

If it doesn't have anything to do with Yang Hongguang.

The teacher of the martial arts school, who didn't do a good job, came to his poor mountain village school...... Why?

At noon, Officer Sun called again.

"Principal Lu, I'll tell you good news! The test results are out!"

Officer Sun's voice was a little uplifting: "In the drinking water sample, the composition of sweet potato starch was tested, and other than that, all other foods are safe." ”

Hearing this explanation, Lu Dongye was really stunned.

The white powder on the edge of the water tank turned out to be sweet potato starch???

Isn't it any other toxic substance?

"Then, Officer Sun, what about the sampling of the incendiary material that Brother Zhao collected yesterday?"

Lu Dongye couldn't help asking, "Is the test result out?"

"That one came out too. ”

Officer Sun replied: "This substance is corn whiskers, there are a small amount of chemicals, I asked about the nature of the pile of substances, it can have a calming effect, it is not volatile, but it can be ignited, and the large dose of combustion does have a hypnotic effect, it is very similar to some kind of prescription sleeping pills, and other harmful ingredients have not been detected." ”

"Okay, thank you, Officer Sun, for telling me. ”

Lu Dongye was relieved: "Didn't Zhuang Bijun provide any other information?"

"Well, not yet, he's hard-mouthed, and he doesn't say anything about the purpose of doing this, and we can't take strong measures. ”

Officer Sun paused slightly, and then said: "However, we checked out some powdered substances in his pocket, and after testing and comparison, it was determined that it was the kind of hypnotic drug, and the source is not known for the time being, but once there is any new development, I will tell you as soon as possible." ”

"Okay, it's really hard Officer Sun. ”

Lu Dongye hung up the phone and came to the kitchen first.

Because, in the school kitchen, there is really a bag of sweet potato starch!

Usually it is used to thicken some soup, and it is not used much.

Lu Dongye specially asked Granny Wang if she used starch to thicken when she was cooking yesterday.

Granny Wang shook her head very resolutely.

So, Lu Dongye determined that it was himself who used starch last time.

I found this bag of sweet potato starch and checked it, and found that the clip at the opening had indeed been moved.

Lu Dongye couldn't help but feel a little dazed...... Could it be that Zhuang Bijun deliberately grabbed a handful of starch and spilled it into the water tank?

What is his purpose in doing this?

Although Officer Sun had already told Lu Dongye that the food and water were safe.

But Lu Dongye still didn't dare to take it lightly, what if there was something undetectable?

He ate all the food that could be eaten raw, drank a mouthful of water from the water tank, and regarded himself as an experimental subject.

It wasn't until the afternoon that Lu Dongye had no adverse reactions, and he finally believed that the food was safe.

In the evening.

Officer Sun made a third call.

"Principal Lu, the results of our investigation are out, first of all, it can basically be ruled out that he has anything to do with Yang Hongguang. ”

Officer Sun gave a detailed description: "We have retrieved ...... In his call records for the past half a month, he has not had any contact with Yang Hongguang, and his mobile phone was located and found in the martial arts school where he worked.

We visited the martial arts school and found that his interpersonal relationship was also normal, and he did not have any intersection with Yang Hongguang. ”

"So, why on earth did he come to our school?"

Lu Dongye was really puzzled: "I didn't even bring my mobile phone, what kind of transportation did I take?"

"The real reason is not clear for the time being, according to his own explanation today......"

Officer Sun's tone seemed uncertain: "He said that he was in a bad mood, he rode an electric car out to relax, but he got lost, the electric car fell into the ditch, he was alone, and I don't know why, so he walked into your village." ”

Lu Dongye couldn't laugh or cry a little: "According to what he said, he really came to our school to steal something to eat? Is this reasonable? Stealing something to eat, and carrying a burning hypnotic drug with him? If you really ask for help, you still use it to hide it and steal it?"

"Yes, there are still many places that can't be explained, so we will investigate further. ”

Obviously, the police didn't believe the wording either: "Oh, by the way, his electric car was found, and it did fall into the ditch he described, but it doesn't prove anything at all." ”

Lu Dongye understood that he really couldn't prove anything.

He said that he fell into the ditch, did he really fall into it?

Is it possible...... Where did he deliberately abandon him?

This kind of thing, when the real motive of the suspect has not been determined, is not qualitative!

After hanging up the phone, Lu Dongye called Chen Muqian, Li Xiaoyu and the village chief to the principal's office.

Here, he told the entire village, all the insiders, the original clues, the clues of Officer Sun's investigation.

As soon as she finished speaking, Chen Muqian was puzzled: "This kind of investigation, there shouldn't be anything to explain, right?" For example, I am Yang Hongguang, and I told my subordinates to find someone to do that Lu Dongye."

Then, his subordinates went to ask others again, and finally found Zhuang Bijun, there are too many contact information in the middle, and the clues are very messy, and it really can't be related to Yang Hongguang!"

Lu Dongye agrees with her point of view.

This is also what he has been considering, but the amount of investigation for this kind of thing is really huge.

Even, if there is a group of people among them, who do not use telephone contact, then there is no way to start.

"Principal Lu, what is a little strange now is that Zhuang Bijun shouldn't be poisoned, right?"

Li Xiaoyu was also puzzled: "Then why did he sprinkle some sweet potato starch into the water tank?"

This is also what Lu Dongye wonders about.

Ignite the hypnotic agent and put Granny Wang to sleep...... As a result, during the half hour that Granny Wang was asleep, this guy just sprinkled some sweet potato starch into the water tank?

However, he did not leave immediately after finishing it, but hid in the kitchen.

This can also show that this is not his intention.

The four of them discussed for a long time, but they didn't guess a possibility.

Before the end.

Lu Dongye instructed them to continue to pay careful attention.

The discussion of this matter can only pass like this.

In the evening, Lu Dongye called Du Liyuan.

briefly explained this matter to her, the purpose of course was to tell Du Liyuan not to worry.

At least, the current findings have nothing to do with Yang Hongguang.

But what I didn't expect was ......

Du Liyuan's reaction was beyond Lu Dongye's expectations.

"What? Zhuang Bijun? Are you sure?"

Du Liyuan's voice seemed a little excited: "The village village, the graduate, the gentleman's gentleman?"
