According to the situation provided by the waiter in the hot pot restaurant, the child was a naughty child.
You can clearly see in the surveillance video that children are running around and playing with paper airplanes.
The three criminal suspects across the screen were not even the first targets of the children.
Before the child's paper airplane flew into their hot pot, the child had hit a woman who was eating next door.
It’s just that the other party is more generous and doesn’t care.
The child's parents did not teach the child a lesson and still allowed the child to play around.
The trigger may have been that after the child's plane entered someone else's hotpot, the parents did not apologize, but instead started a quarrel with the parent.
In the words of the waiter's recollection, the parents thought that the child was so young and didn't understand anything. How could three grown men compete with the child?
Wang Song’s investigation has made significant progress.
Although there are still no facial features of the three suspects in the surveillance, the reason why the victim's family of three was exterminated has been found.
It may be funny to say that the reason is because the child played with a paper airplane and flew into the other party's hot pot, causing the family to be wiped out.
But...
Combined with the identity of the criminal suspect and the fugitive, it is actually not difficult to understand.
Wang Song has been a criminal police officer for more than 20 years and has arrested many wanted criminals.
These wanted criminals at large can be roughly divided into two categories.
One type is those who are wanted and have no scruples while on the run, acting casually, killing when they want, and robbing when they want.
It can be said to be extremely arrogant.
But there is also a group of people who are wanted on the run and live anonymously, walking on thin ice and being frightened half to death when they hear the sound of police sirens.
In comparison, the latter account for the majority of fugitives.
People who lick blood from the tip of a knife often have great fluctuations in their hearts, and no one knows what they will do after being stimulated.
"I have started investigating the surveillance that night."
"Although the other party's face was not photographed in the hot pot restaurant, with this clue, we may be able to find some information from the surveillance on the street. ”
After listening to Wang Song’s report, Li Donglin secretly breathed a sigh of relief.
The clue of surveillance video has not been broken, and there has been significant progress. This is good news.
Of course, it does not mean that with surveillance information, the case can be solved or the suspect can be caught.
Even if the face is photographed, it is not easy to catch the other person and confirm the other person's identity.
At the same time, Lu Chuan was in the car rushing to Qinzhou.
He wanted to confirm one thing.
This is a detail of the Qinzhou 116 case.
According to the file, the investigators at the time did not find any evidence left by the suspect in the bedroom where the crime occurred.
It's easy to tell about footprints. When the other party left, he used a mop to mop the floor, and the footprints were indeed gone.
Fingerprints are easy to talk about. As long as the other party wears a pair of gloves, they will naturally not leave fingerprints.
One of the fingerprints may also be damaged.
But what about body hair?
The other party killed five students that night, six to be exact, but one of them was lucky and did not die.
Having sex with so many people and not leaving even a single hair on your body?
How did the other party do it?
At seven o'clock in the evening, it was already dark when Lu Chuan arrived at QZ City Vocational and Technical College.
The person in charge of receiving Lu Chuan was his old acquaintance Qin Hui, the captain of the Qinzhou City Criminal Investigation Detachment.
"Lu Da is investigating, we haven't seen each other for two or three months since the last time we saw each other!" Qin Hui was very enthusiastic, and as the captain of the QZ City Criminal Investigation Detachment, he personally greeted Lu Chuan, giving him enough face.
Lu Chuan saluted.
The other party came to pick me up because he helped the QZ City Criminal Investigation Detachment solve the case, but because of this, he cannot accept the other party's respect as a matter of course.
I am a small detective, but I am a leader at the same level as Qin Yong, so of course I have to salute.
What's more, he wants Qin Hui and the others to help him when he comes here this time.
"Hello, detachment Qin!"
"Haha, Xiao Lu and I won't use this false salute. Come on, come on, come to my office for a cup of tea first."
"I'll Treat me, let’s have a drink!”
“Detachment Qin, you are too polite.”
Lu Chuan did not propose the matter directly, but went to the office with Qin Hui first.
Qin Hui really paid attention to Lu Chuan's arrival. Otherwise, he would have left work at this time.
"Qin Detachment, I came here mainly to see the files of Case 116 and some of the evidence discovered that year."
In the office, after chatting for a while, Lu Chuan proposed The purpose of his trip.
"That's no problem. Li Chu has called me this afternoon. We will fully cooperate with you!"
Qin Hui attaches so much importance to Lu Chuan's arrival, not only because of his personal relationship, but also because of his personal relationship. It wasn't just Lu Chuan who helped his detachment solve the case, the more important reason was the 116 case three years ago.
The case back then could be said to have skinned the QZ City Public Security Bureau.
The reason why I became the leader of this detachment is because of this 116 case.
Qin Hui was the deputy captain of the criminal investigation detachment back then. The captain resigned because of this case and went to the traffic police detachment.
I am still worried about this case.
And after Qin Hui came up...
In fact, there was little progress. Although Qin Hui was the deputy detachment leader back then, he was involved in the investigation of the case from beginning to end.
The reason why the detachment leader was transferred to the traffic police detachment was because someone had to take responsibility for the case not being solved.
Qin Hui originally thought that this case might just hang on forever, but he didn't expect that Director Li Donglin called him this afternoon, which brought a new turning point.
"Xiao Lu, speaking of this case, Chu Li told me today that the murderer in the massacre case in Tianzhou City was one of the murderers in Case 116?"
Lu Chuan nodded. : "This should be certain."
"I found a trace on the cupboard at the scene of the murder, and this trace is consistent with the trace left on the wall by the murderer in the 116 case."
"The murderer's fingerprints are very special. He should have been injured. Injured or deliberately processed. ”
But no matter how it is processed, although the finalized fingerprint does not have the characteristics of ordinary fingerprints, the uniqueness will not change.
This is also the reason why Lu Chuan suggested merging the case for investigation and came to Qinzhou in person.
Wang Song and Song Mingguang are tracing the surveillance video, but surveillance is accidental.
The opponent's anti-reconnaissance awareness is very strong, otherwise he would not sit behind the screen and eat in the hot pot restaurant with his back to the surveillance camera.
Even if there was a conflict with the victim's family of three, they still did not appear under surveillance, which showed that the other party was cautious.
To deal with such an experienced criminal suspect, it is impossible to catch him by just relying on surveillance.
"I have had the files and evidence sorted out and they will be sent over in a moment. Let me tell you about the case back then..." (End of Chapter)
