Qin Shanhai raised his eyebrows: "Early love is a social problem, neither the family nor the school will support this kind of behavior, but Quan Haokang's mother reacted too violently, and probably thought that Nie Xiaorou was not worthy of her son, so she would pick her nose and eyes, and she didn't look down on Nie Xiaorou at all." ”

Du Wenbin sighed and said: "As far as we know now, the deepest enmity with Quan Haokang's family is estimated to be Nie Xiaorou's family, you look at Quan Haokang's mother's attitude, including his father, it is estimated that these two young people have not been stopped before." ”

Wu Hongwei frowned when he heard this and said, "Do you want us to investigate, what did Quan Haokang's parents do to Nie Xiaorou before?"

Du Wenbin shook his head: "That's what I said, you really take it seriously, it was these two students who were hunted down." ”

Qin Shanhai squatted on the ground for a while, and after hearing this, he got up from the ground, patted the soil on his hands, and subconsciously said, "How did you say that the murderer found the two of them?"

It stands to reason that Quan Haokang and Nie Xiaorou ran away from home, and even their parents are not sure of their whereabouts, so how did they determine the murderer?

And the most important thing is, why do these two people appear around here at night? It's so remote here, and no one usually wanders around here at night, so what are the two of them doing here?

Now we can judge according to the fact that Nie Xiaorou was not killed by the murderer, the murderer and Nie Xiaorou should have no grudge, so the murderer's hatred is only against Quan Haokang alone.

The murderer can determine the whereabouts of the two people when they run away from home, does it mean that the murderer has been following Quan Haokang and has been looking for an opportunity to kill Quan Haokang. ”

Hearing Qin Shanhai say this, the two of them suddenly had a feeling of sudden realization, they had been putting the key to the problem on the family side of Nie Xiaorou and Quan Haokang before, and they actually ignored this problem.

Why did these two people run to the suburbs at night and stay in a place where no one was, and how did the murderer find the two of them?

After Qin Shanhai raised this question, the scene fell into silence, and no one could say why.

After thinking about it for a long time, Qin Shanhai had no choice but to wave his hand helplessly: "Forget it, it's not time for us to think about this issue now, let's take a turn along the route of the two escapes first and see if we can find any clues." ”

After Qin Shanhai finished speaking, the three of them split up and began to look around, in fact, the three of them didn't know what they were looking for, but they were looking around again and again with absolutely no suspicious places in their hearts.

After Qin Shanhai and the others walked around three or four times, they didn't find anything suspicious except for the footprints that remained on the ground.

From morning to noon, still nothing, Du Wenbin was really tired, and shouted, Otherwise, let's come back next time, Qin Shanhai glared at him and ignored him.

Qin Shanhai walked along the escape route again, the more he walked, the more he felt that there were some places that made him very confused, he still remembered the shape of the footprints left by the three people in his mind, the footprints of Nie Xiaorou and Quan Haokang, which were messy and eager, it could be seen that the two of them were nervous when they escaped, but the murderer's footprints were very steady, and there was no panic at all.

The murderer was so sure that the target was not beyond his control, and the direction was not wrong in the slightest, so he silently followed behind the two people, even if he was lame.

How much self-confidence does the murderer have to be in order to follow the two of them from beginning to end without panic? Now Qin Shanhai is very curious, what kind of person is this murderer?

Because he walked several times, Qin Shanhai was so tired that he couldn't walk on both legs, and after squatting down and observing the footprints for a while, when he stood up, his brain was a little insufficient, his eyes began to burst stars, and he subconsciously held on to the wall next to him.

After a few moments, he recovered, and just as he tried to withdraw his hand from holding the wall, he noticed something unusual on the wall.

This is a corner into the abandoned factory, where the walls are in disrepair and covered with a black stain, but on top of this stain, there is a trace of white chalk.

Someone was holding a white chalk and drew a horizontal line at this corner, looking at this horizontal line, Qin Shanhai was stunned for a moment, the traces left by this white chalk are still very new, it seems that someone just drew it not long ago, after all, this piece has not been here for a long time, who drew a horizontal line here, this horizontal line is not long, about four or five centimeters, it should be drawn casually.

Why did you draw this horizontal line? Is it because you are idle and have nothing to do? Qin Shanhai looked at this horizontal line curiously, he frowned and suddenly began to walk forward.

Then at the corner where Quan Haokang and Nie Xiaorou escaped, they found this horizontal line again, which also seemed to be drawn casually, and it was also a trace of white chalk.

Qin Shanhai's whole body stiffened, this is definitely not a coincidence, otherwise why is it the direction of the two people escaping, there is such a horizontal line at the corner.

This is simply a mark, as if to remind the murderer behind him that the target's position is heading.

The more Qin Shanhai looked at it, the more incredible he felt, he quickly called Du Wenbin and Wu Hongwei over, and asked the three of them to look at the mark left by the white chalk, and the two of them were all stunned when they saw it, what does this mean?

Was this just to remind the murderer of their location? Who left this? The footprints at the scene prove that there were only three of them who came to the abandoned factory at that time.

Does it mean that this is left by one of the three of them, excluding the murderer, only Quan Haokang and Nie Xiaorou are left.

Now that Quan Haokang is dead, does that mean that the mark that left their position was left by Nie Xiaorou?

The three of them thought of this at the same time, and for a moment none of them could say anything, and all of them were frightened by their own speculation.

The mark was left by Nie Xiaorou, why did she leave such a mark? Could it be that Nie Xiaorou wanted to see Quan Haokang die? Or did she want to see the two of them die together, this is simply incredible.

"Let's not think about it, let's notify the county bureau of this matter first, and let the technicians take pictures of all these white marks. Qin Shanhai said calmly.

Du Wenbin and Wu Hongwei nodded, now they can only do this first, the three of them returned to the county bureau non-stop and reported this important clue to Jiang Qiang.

Jiang Qiang was also very surprised when he heard this.

No one expected that things would go in this direction.

If the mark was left by Nie Xiaorou, although they are not sure yet, based on the clues they have now, they can only temporarily speculate that Nie Xiaorou left a mark indicating their direction.

But why did she do this? Isn't Quan Haokang Nie Xiaorou's boyfriend? Nie Xiaorou wants to see Quan Haokang die.

Feng Zhe thought of this and suddenly said loudly: "Do you think Nie Xiaorou is pretending? She actually just wants Quan Haokang to die, so she pretends to be crazy and stupid, so that we think that she is crazy, and she can't say anything when she is stimulated, and she also shows that she is also a victim?"

After Feng Zhe said this, everyone did not speak, did not agree, and no one denied it, but although they did not say anything, there were still some who agreed with what Feng Zhe said.

If this mark was really left by Nie Xiaorou, then all the previous cognitions would be overturned, and the purpose of Nie Xiaorou's mark was to mark their location at this time.

This also explains why the murderer only killed Quan Haokang, but did not kill Nie Xiaorou, because Nie Xiaorou is likely to be an accomplice.

The more Qin Shanhai thought about it, the more he felt that this possibility was very high, otherwise an extremely murderous murderer, after seeing that there was still a witness left, did not kill Nie Xiaorou, or even did not do anything to her.

After the doctor's examination, Nie Xiaorou was not physically harmed except for being mentally stimulated.

Before, they speculated that the murderer might have only one target, but now that they think about it, Nie Xiaorou may be an accomplice, and it is precisely because she is an accomplice that she survived.

Jiang Qiang suddenly said: "No, we must control Nie Xiaorou well, at least to determine if Nie Xiaorou is really crazy now, if she is pretending to be crazy?"

Speaking of this, Qin Shanhai suddenly interjected: "By the way, think about it, when we went to the door of the ward, didn't Quan Haokang's mother fight with Nie Xiaorou's mother?"

At that time, we were still afraid of affecting Nie Xiaorou inside, but when we went in, we found that Nie Xiaorou was in a state of self-protection, of course, this is also the conclusion of the doctor, Nie Xiaorou is too stimulated by it, so she is now in an unconscious state of self-protection, she can't hear what others say, and only stays in the chaotic world, but when we want to go out, Nie Xiaorou suddenly began to struggle! Unless Nie Xiaorou was stimulated again, but we didn't do anything excessive at that time. When I asked Nie Xiaorou a question before, she didn't respond, but when we were about to leave, she suddenly started struggling frantically?!"

After Qin Shanhai's reminder, Du Wenbin and Wu Hongwei also reacted, after all, this involves psychological and spiritual problems, and laymen like them didn't care too much about the details of Nie Xiaorou's sudden reaction.

It can only be attributed to the fact that Nie Xiaorou is crazy, but now that I think about it, is Nie Xiaorou just trying to make the police think that she is crazy, so she will behave like that?

If Nie Xiaorou is really an accomplice, then what she did before is very debatable, and her previous performance in the hospital may really be to fool them.
