Leng Tong drove quickly back to the scene of the crime on Jingwei Street, at this time there were several police cars parked in front of the door, the general case may be two police cars, this time it is five, it should be that the location of this case is still on Jingwei Street, it is very sensitive, and it is the third homicide case in a row.

As soon as the two of us came in, we heard Huang Lao's voice ask, "What were you doing at that time?" ”

The girl's mother cried bitterly and said: "I'm applying a mask, because it's so late, and I'm afraid of coming out to scare the customer, so I didn't come out, so I let the child do my homework outside, although the child is still young, but someone can talk when someone comes, and wait for the child's father to come back." ”

Dong Lao asked, "Then did you hear any sound?" ”

"I vaguely heard the child talking to a man, I thought it was the child's father who came back, so I didn't care." The woman cried and said: "Then the child was silent, I thought it was a customer, maybe I wanted to buy something, and I left, otherwise the child would call me, who knew that after a while, this kind of ······ happened"

Leng Tong and I also came in at this time, the two elders, Yang Ju, Xing Team, Zhang Team and others were all there, Da Leizi also retreated to the side to watch, everyone also looked at each other, there was no evidence left at the scene at all, and we had roughly seen it when we left just now.

Huang Lao asked again what the girl's father was doing, and I also listened while coming to the table, and looked at the notebook and pencil on it, which were all well placed, and the homework book was also placed there.

The cause of the child's death basically doesn't need to be seen, everyone knows in their hearts that it was strangled to death.

Through the process of these cases, I feel that there is a common place, that is, the murderer and the victims of the next two cases have talked, the first case because there was no one at the scene of the crime, it is impossible to determine whether there was a conversation, I think the murderer in the first case should have also talked to the victim.

Then the content of the conversation is very suspicious, what exactly did they say? Could this topic be the cause of the murderer's murder?

I was about to go over to communicate with Leng Tong, when I suddenly saw that there seemed to be some problems in the child's homework book, so I quickly leaned down and looked at it carefully.

The child is doing a math problem in the homework book, the child should be preschool, this problem is seventeen minus eight is equal to a few, and nine is written after the equal sign, but this nine characters are lighter than the previous handwriting, and it is also a little neater, which makes me a little strange.

When I looked closely, I found that this nine-character was changed later, and the place where the nine-character was originally written was erased with an eraser, probably because the child was very hard, and the handwriting that was erased was eleven.

I hurriedly looked at the front, there are also a few nine characters in the front of the homework book, but it is a little different from this nine characters, the handwriting is heavier, and the upper circle of the nine characters is not sealed, only this nine characters are sealed, and a complete circle is drawn!

Is this a child's handwriting? Or the nine characters written by the murderer?

There is no one outside, and the child's mother is wearing a mask inside, which should not have come out for a while, so the child should have miscalculated, could it be the handwriting written by the murderer?

Children are generally more forceful, and the handwriting is slightly heavier, but this nine-character character is obviously lighter, and it is very likely that the murderer erased it off the child and corrected it.

But this doesn't make sense, the murderer killed this child, and it is impossible to help the child with his homework again, unless he is mentally ill!

Anyway, I still saw a little abnormality, I can't talk to others, and Leng Tong can be said, so I hurriedly went over and pulled Leng Tong over, everyone was over there to inquire about the situation, and I also told Leng Tong about my findings.

Leng Tong also attached great importance to it, and hurriedly leaned down to look at it carefully, and soon compared it with the nine characters in front of him, it was really different, and he also looked up at me with a blank face.

I looked at Leng Tong and whispered, "Tongtong, do you think this is a little different?" Is it possible that the murderer has changed? ”

"This nine-character is sealed, which is different from the previous one, and the handwriting is relatively light." Leng Tong also nodded and said: "Although this is a little unreasonable, but after all, it is a little different, it is better to tell everyone, what if the murderer's fingerprints are extracted on the pencil?" ”

I nodded, originally I also meant this, but seeing that it was not the same as what the child wrote, I turned my head and said, "Team Xing, there are suspected traces of the murderer here." ”

Everyone was asking, and when they heard me say this, they all hurriedly gathered around, and there was no trace left at the scene of the crime in the past.

I pointed to the child's homework book and said, "This nine-character is obviously erased, and the handwriting is light, and the circle is sealed, which is different from the nine-character written in front of the child." ”

Everyone looked at it carefully, and someone should have read it just now, but the child's homework book, no one should have thought of anything to do with the case, and they all looked at it very seriously at this time, nodding their heads from time to time.

I looked at the girl's mother and asked, "How is your daughter's math?" ”

"The child is still young, five years old, and he has never been to preschool, so it is no problem to know how to count, but it is not good to count." The woman immediately said: "Every time it is reduced to nine, some will not count." ”

I looked at Leng Tong, and then asked, "So in the process of the child's homework, did you come out?" Have you ever given guidance to your child? ”

"I didn't come out!" The woman also cried and said, "If I come out, can this kind of thing happen?" When the child's father comes back in a while, how can I explain it? How can I live? ”

When I looked back, everyone looked at each other, and soon said that this discovery was very valuable, and the two elders were indeed masters, so I asked the people from the trace examination department to bring back erasers and pencils to see if they could extract the murderer's fingerprints.

The scene is very simple, everyone quickly finished investigating the scene, got into the car one after another, and there is no need to rest now, it is another case, or at this time period, go back directly to the meeting to study the case.

In the small conference room of the Shao City Police Station, everyone sat around the round table, and the two elders spoke, asking everyone to express their views on this case.

Team Zhang was naturally the first to say it, mainly to say that the murderer was extremely bold and arrogant, and killed two people in a short period of time, which can be said to be almost crazy.

I started patrolling Jingwei Street tonight, but I didn't expect the murderer to kill at the entrance of Jingwei Street, and I also reviewed his negligence.

The others didn't say anything, and there really wasn't much to say, and there were no valuable clues at the scene other than the suspicious clues I found.

Probably because I found some clues, Huang Lao's eyes quickly turned to me.

I immediately said: "The murderer is indeed extremely bold, one day apart, two crimes in a row, and in the latter two cases, there are signs of communication with the victim, which is very suspicious, I think it may be related to the murderer's motive for killing." ”

Everyone immediately discussed that it was indeed the case in the latter two cases, and no one was present in the first case, so there was no way to investigate it.

As for what the murderer communicated with the victim, this is likely to be the crux of the matter, but there is no way to guess, and no one can explain that the murderer had the urge to kill in a few words.

At this time, the people from the trace examination department at the door came in to report, and no valid fingerprints were extracted on the pencil and eraser, and even the only possible clues were broken!

Dong Lao glanced at everyone, and then put forward three suggestions for everyone to discuss, one is what the murderer may say to the victim, one is what words can make the murderer have the idea of killing in an instant, and the other is whether the handwriting on the homework book was left by the murderer.

Now there is everything to say, and some say that it is a perverted murderer, as for the handwriting, no one can say anything, I am not sure.

Suddenly, a rough voice said angrily in a row of urns behind him, "Could it be someone like the Rift Girl?" ”

Everyone followed the sound and saw that it was Da Leizi, who seemed to have slept in the back, and such a sentence came out with sleepy eyes, and Team Xing was about to scold him, but Team Zhang asked: "Little Leizi, you should tell me, what is a rip girl?" ”

"This······ I've heard that too! Da Leizi just took a shot, but he didn't expect Team Zhang to ask, and said helplessly: "It's just a devil, come out and ask people, if she is good-looking, if she is good-looking, she will tear people's mouths open, and she will become like her, if she is not good-looking, she will eat people directly, or kill them." ”

Huang Lao smiled and said: "This is a legend of Dongying, I have also heard of it, it is said that it happened in seventy-nine years, it is all a legend, it can't be true, but this murderer is really a little similar, otherwise he wouldn't have the idea of killing people in an instant." ”

"Yes, yes!" Da Leizi hurriedly said: "Huang Lao is right, experts are powerful, they know more than them!" ”

This offended a large area, and Team Xing hurriedly turned around and glared at Da Lei Ziyu, telling Da Lei Zi to shut up, don't talk nonsense, this is indeed a shadowless thing.

Da Leizi didn't dare to say anything, the conference room was quiet, no one could tell what was going on, and the two elders could only say that they would study it again, and the time was not too early, and the meeting was soon dismissed.

On the way back to the guest house, I whispered to Leng Tong: "Tongtong, our idealized inference can be established in time, but in objective reality, it is not valid, there are patrolling policemen on the road, if the murderer passes, can he still escape?" ”

"Not necessarily!" Leng Tong immediately said: "I've seen it, between those businesses, not all of them are houses that are connected side by side, and some have alleys behind them, such a long street, the murderer can completely avoid the patrolling police." Taking a step back, the police didn't find out about the crime, even if they met the murderer and had a suitable identity, what can't they do? ”

I was slightly stunned, and also remembered the terrain of Jingwei Street, it is indeed the same as Leng Tong said, you can avoid patrolling police in the alley, and the explanation behind is also reasonable, as long as you are not caught at the scene, and the murderer has no clues left, then the police can't see one and catch one.

I thought for a moment before I whispered, "Then did you say that the handwriting was left by the murderer?" ”

"I guess so!" Leng Tong nodded and said: "Although there are no fingerprints, the murderer is wearing gloves, but I don't understand, why did the murderer modify the girl's homework book?" ”
