After sending off Comrade Lao Nie, Gu Chen and Lu Weiwei put on their coats and slept on a folding bed in the office for one night.

Due to the urgency of the case, Lu Weiwei was not sure whether Officer Wang needed to assist, so she had to stay in the office and provide information inquiry services at any time.

And Gu Chen volunteered to work overtime, after all, it was the case he participated in, and it was the first homicide case, Gu Chen was more cautious than usual.

"Senior Sister Lu, it's six o'clock in the morning, why haven't they come back yet?" Gu Chen stretched, he slept well this night.

Lu Weiwei waved her hand, confused: "Don't care so much about Senior Brother Gu, just sleep with you, everyone has a division of labor, just do our job well." ”

Gu Chen thinks about it, it makes sense, the sky is falling and Wu Dalang is on top of it, what are you thinking about?

Thinking of this, Gu Chen got up and went to the toilet to pee, but he was actually awakened by urine.

Seven o'clock in the morning.

The old comrades with a circle of panda eyes are back, and everyone is unkempt, as if they have just come out of the mine.

Gu Chen had already bought everyone's breakfast and put it on everyone's seats, and the old comrades could start breakfast as soon as they came.

"Thank you Gu Chen. Officer Wang patted Gu Chen on the shoulder.

"Senior Brother Wang, how is it going?" Gu Chen looked at Officer Wang curiously, his eyes were bloodshot now, he must have not slept all night.

"The murderer of the deceased has been caught, and there is a debt dispute with the deceased, and both of them are co-workers on the same construction site. ”

Officer Wang took a few sips of soy milk: "And as you deduced, we inferred from this guy that he bought glass glue and glass, and he was the murderer of the victim." ”

"This guy...... When he saw us rushing into the room, he was stupid, maybe he would never have dreamed that the suicide scene in the secret room that he had carefully arranged would be cracked by us. ”

Another veteran comrade could not hide the excitement in his heart.

In fact, everyone is holding their breath in their hearts......

If we want to talk about three criminal investigation teams, why are the three groups just children picked up in the garbage heap? All important cases are thrown to one group or two teams to investigate?

Officer Wang's rush to the task this time can be said to be snatching food between a group of two sets of teeth, and the pressure can be imagined.

But who would have thought, who would have thought of it......

It was just one night, and everyone wore the stars and the moon, and stayed up all night to investigate the murderer and arrest him.

Officer Wang is still in the midst of the pain and pleasure.

He has never been so friendly to probationary police officers, but Gu Chen is an exception.

As the saying goes, adversity sees true love, and this sentence couldn't be better here.

When you enter the scene of the crime, you can't find the subtle clues like the windowsill without keen observation.

Even Officer Wang, an experienced veteran policeman, will also be negligent, but Gu Chen's performance is very eye-catching.

How difficult is this kind of observation? The glass glue only has a subtle color difference, which is difficult to judge unless you observe it carefully.

And Gu Chen also did a very good job of finding clues, he knew that the murderer couldn't get out from the gate at all, and the only possible place was the window.

The window was in a state of anti-lock at that time, but Gu Chen was able to use the judgment of small clues to boldly deduce that after the murderer used a glass knife to cut the window, he drilled out of the room, and then reinstalled it with a new piece of glass, and patched up the glass glue.

This kind of thing is unimaginable to ordinary people, and even if you want to find out about it, you need the experience of a professional police officer.

No one can do it so well from the beginning, and that requires continuous accumulation of cases, from simple cases to complex cases, and continuous learning and improvement.

It's like doing math problems, simple addition, subtraction, multiplication and division can't do it, and if you want to improve to a high math level, it's tantamount to a fool's dream.

Through this precise reasoning, Officer Wang learned that Gu Chen's criminal investigation skills were even more powerful than those of ordinary experienced old policemen.

It is not difficult to reason correctly, nor is it difficult, but only after experiencing the baptism of large and small cases, coupled with the experience of various unexpected situations, can you still win steadily and reason accurately, then not everyone can do it.

Now, if Gu Chen is allowed to investigate this case independently, it will definitely have the same effect.

"Senior Brother Wang, can you tell me more about the murderer's motive for committing the crime?" Gu Chen, who missed the arrest, still wanted to summarize this case.

"By the way, aren't you tired kid?" Officer Wang, who was so tired that he couldn't do it, wanted to be quiet at the moment, he couldn't be as energetic as a young man.

"But...... I slept all night yesterday and I'm not tired. Gu Chen replied.

Officer Wang suddenly remembered that he had led a group of people to arrest him last night, while Gu Chen was having a tryst with Duke Zhou.

Thinking about it, I suddenly felt like I had been hit by 10,000 critical hits.

At this time, Lu Weiwei happened to receive a fax, and Officer Wang immediately asked, "Is it a fax from the Technical Department of the Municipal Bureau?"

"That's right, it's forensic Liu. Lu Weiwei tore down the fax and handed it to Officer Wang.

"I'm Tarzan next door, grasping the vine of love, listen to me, oh Ou Ou...... You are beautiful Jenny, take me by the hand and wander the world, oh Ou Ou ......"

At this time, Officer Wang's mobile phone rang as well.

"Lao Wang, have you received the fax report?" came from Forensic Doctor Liu's inquiry on the other end of the phone.

Officer Wang immediately said, "Just received it." ”

"According to my analysis, according to my technical appraisal, there is an 80% chance that the deceased was homicide, so this may be a premeditated murder in a closed room. ”

The results of Forensic Liu's technical appraisal also just verified Officer Wang's thinking, and Officer Wang just wanted to speak, but Forensic Liu took the lead.

"Lao Wang, I have also seen the scene, I think this case is a little difficult to handle, how did the murderer flee the scene unconsciously after killing someone, I have been engaged in forensic medicine for so many years, and I have never encountered such a strange thing. ”

"Forensic Doctor Liu, I ......"

Officer Wang craned his neck proudly, and the words were still in his mouth, but Forensic Doctor Liu took over the right to speak again.

"Lao Wang, this case is a hot potato, if you let one group and two teams investigate, you don't have to be so embarrassed. Forensic Doctor Liu is also quite interested in this closed room murder.

Otherwise...... He will not stay up all night to make the analysis report, and the situation on the scene really makes him scratch his head.

In a case of homicide, how could the murderer leave the scene unnoticed when the doors and windows of the room were all locked?

"Forensic Doctor Liu, what I want to say is that the murderer has been arrested by us last night, and he has already pleaded guilty, so ...... Thank you for your cooperation. ”

Officer Wang's words seemed to be like a burst of thunder, which suddenly made Forensic Doctor Liu stunned.

It's like being frozen to death after ten years of hard work, but you secretly brought a hot water bottle.
