After sending Comrade Nie away, Gu Chen and Lu Weiwei put on their coats and slept one night on the folding bed in the office.
Due to the urgency of the case, Lu Weiwei was not sure whether Officer Wang needed assistance, so she had to stay in the office and provide information inquiry services at any time.
Gu Chen, on the other hand, voluntarily worked overtime. After all, it was the case he was involved in and it was the first murder case. Gu Chen was more cautious than usual.
"Senior Sister Lu, it's already six o'clock in the morning, why haven't Senior Brother Wang and the others come back yet?" Gu Chen stretched out and had a good sleep this time.
Lu Weiwei waved her hands, confused: "Don't worry about so many Junior Brother Gu, just go to sleep. Everyone has their own division of labor, we just have to do our job well."
Gu Chen thought about it and it made sense. If the sky fell and Wu Dalang was holding it up, why would he worry about it?
Thinking of this, Gu Chen got up and went to the toilet to urinate. In fact, he was woken up by peeing.
seven in the morning.
The old comrades with panda eyes are back. Everyone is unkempt and looks like they just came out of the mine.
Gu Chen has already bought everyone's breakfast and placed it on everyone's seat. Breakfast can be started as soon as the old comrades arrive.
"Thank you Gu Chen." Officer Wang patted Gu Chen on the shoulder.
"Senior Brother Wang, how is the progress?" Gu Chen looked at Officer Wang curiously. His eyes were bloodshot now. He must have been awake all night.
"We have been caught. The murderer of the deceased had a debt dispute with the deceased. They were both co-workers on the same construction site."
Officer Wang took a few sips of soy milk: "And as you can infer, we bought glass glue and glass from this guy and concluded that he was the murderer of the victim."
"This guy... was so frightened when he saw us rushing into the room. Maybe he never dreamed that the secret room suicide scene he had carefully arranged would be quickly cracked by us."
Another old comrade could not conceal his excitement.
In fact, everyone is holding a breath in their hearts...
There are three criminal investigation teams, why are the third team just kids picked up from the trash? All important cases are left to the first and second teams to investigate?
Officer Wang's task this time can be said to be to grab food between the teeth of one group and two groups. You can imagine the pressure.
But who can think of it, who can think of it...
In just one night, everyone stayed up late to investigate and arrest the murderer.
Officer Wang is still calmly experiencing pain and joy.
He has never been so friendly to trainee police officers, but Gu Chen is an exception.
As the saying goes, a friend in need is a friend indeed, and this sentence couldn't be better placed here.
Entering the crime scene, without keen observation, it is impossible to detect subtle clues like the window sill.
Even Officer Wang himself, an experienced police officer, would be negligent sometimes, but Gu Chen's performance was eye-catching.
How difficult is this kind of observation? There is only a slight color difference in glass glue. Unless you observe carefully, it is difficult to make a judgment.
Gu Chen also did a good job in finding clues. He knew that the murderer could not get out through the door. The only possible place was through the window.
The window was locked at the time, but Gu Chen was able to use small clues to judge and boldly deduced that the murderer used a glass knife to cut the window, got out, and then reinstalled it with a new piece of glass and added glass glue.
This kind of thing is simply unimaginable to ordinary people. Even discovering this situation requires the experience accumulation of a professional police officer.
No one can be so good at the beginning. It requires continuous accumulation of cases, from simple cases to complex cases, continuous learning and improvement.
This is like doing math problems. You can't even do simple addition, subtraction, multiplication and division. If you want to improve to a high level of mathematics, it's just a dream.
Through this precise reasoning, Officer Wang learned that Gu Chen's criminal investigation skills were even better than those of ordinary experienced police officers.
A correct reasoning is not difficult, nor can it be called difficult, but only if you have experienced the baptism of large and small cases again and again, coupled with the experience of various emergencies, can you still win steadily and reason accurately, then it will be difficult.
Anyone can do it.
Now if Gu Chen is allowed to investigate the case independently, it will probably have the same effect.
"Senior Brother Wang, can you tell me the murderer's motive in detail?" Gu Chen, who missed the arrest, still wanted to summarize the case.
"By the way, aren't you tired?" Officer Wang was so tired that he just wanted to be quiet at this moment. He couldn't be as energetic as a young man.
"But... I slept all night last night, I'm not tired." Gu Chen replied.
Officer Wang suddenly remembered that he and a group of people worked hard to arrest last night, but Gu Chen was having a tryst with Duke Zhou.
Thinking about it, I suddenly felt like I was hit by a 10,000-point critical hit.
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 signed by Forensic Doctor Liu." Lu Weiwei tore off the fax and handed it to Officer Wang.
"I am the Tarzan next door, grabbing the vine of love, listen to me, oh oh oh... you are the beautiful Jenny, holding my hand and wandering around the world, oh oh oh..."
At this time, Officer Wang's cell phone also rang.
"Lao Wang, have you received the fax report?" Forensic Doctor Liu asked from the other end of the phone.
Officer Wang immediately said: "Just received it."
"You can take a look at my analysis first. According to my technical appraisal, there is an 80% chance that the deceased was a homicide. Therefore, this may be a premeditated secret room murder."
Forensic Doctor Liu's technical appraisal results also verified Officer Wang's thinking. Just as Officer Wang was about to speak, Forensic Doctor Liu took the lead.
"Old Wang, I have also seen the scene. I think this case is a bit difficult to handle. How did the murderer escape from the scene without anyone noticing after killing someone? I have been practicing forensic medicine for so many years and I have never encountered this kind of case.
Weird things."
"Forensic Doctor Liu, I..."
Officer Wang raised his neck proudly, his words still on his lips, but Forensic Doctor Liu took over the right to speak again.
"Old Wang, this case is a hot potato. If you had let one and two teams handle the investigation, you wouldn't have been in such a difficult situation." Forensic Doctor Liu was also very interested in this secret room murder incident.
Otherwise... he wouldn't have stayed up late to make the analysis report. The situation at the scene really confused him.
In a case that was technically diagnosed as homicide, how could the murderer leave the scene without anyone noticing when all the doors and windows of the room were locked?
"Forensic Doctor Liu, what I want to say is that the murderer was arrested by us last night, and he has confessed, so... thank you for your cooperation."
Officer Wang's words were like a burst of thunder, and Forensic Doctor Liu was suddenly stunned.
This is like studying hard for ten years and freezing to death, but you secretly brought a hot water bottle.
