You're supposed to be a security officer, what case are you solving?

Chapter 9 Analysis!

Yang Jinwen was not making baseless accusations.

It was a decision made after careful consideration; to catch the murderer, we cannot investigate cases based on habitual thinking.

If you don't take some initiative, you'll keep making mistakes like arresting the wrong person or going down the wrong path.

He Jinbo and Zheng Kang are both veteran criminal police officers with sharp eyes and keen minds.

If we were to give them clues little by little like we did yesterday, we might end up losing more than we gain.

Moreover, this is taking too much time. If the person cannot be found today and tomorrow, then the second victim, Jiang Yan, will be in danger.

He doesn't have much time left!
How capable can a trainee police officer be?
If it weren't for his connection with Deputy Director Lu Shaohua, he would still be guarding the gate in the security department, let alone wanting to get involved in the major crimes team's criminal homicide cases.
That's wishful thinking!

Yang Jinwen got up very early, didn't even have breakfast, and rode his old bicycle to the bureau.

He was very familiar with the North City Branch Bureau; every blade of grass and every tree was etched in his memory. After all, it was the police unit he had worked for in his previous life.

According to regulations, he had to go to the steel plant today to retrieve his personnel file, and then go to the personnel department of the Chengbei branch to complete the procedures. This process would take several days, but he didn't have the time right now.

He had made the clue board for the 5*30 major serial murder case several times in his previous life, and he also combined it with some contents from the case file. Of course, he also avoided important information that he shouldn't have known.

For example, regarding the autopsy, because of his intervention, Huang Cuicui's body was discovered three days earlier, which naturally changed from her previous life.

Even so, Yang Jinwen filled four whiteboards with his writing and went through three different chalks.

When he finished writing the last sentence, dozens of people in the Major Crimes Unit gasped and stared at Yang Jinwen as if he were a monster.

He Jinbo put his hands on his hips, swallowed hard, and exchanged a glance with Zheng Kang. Both of them saw shock and disbelief in each other's eyes!

Is this a new police officer who's been on the job for less than a day?

People believe it when they hear that the investigators are from the provincial department.

He Jinbo knew that the people in the Municipal Public Security Bureau were not much better than the front-line police officers, except that their technical equipment was more advanced than that of the Chengbei Branch Bureau.

Yang Jinwen put down the chalk and, just like when he was a leader in his previous life, habitually asked the others, "Do you have anything to add?"

"Huh?" The veterans of the Major Crimes Unit shook their heads in unison, looking at each other in bewilderment.

Zheng Kang looked pained. The roles of offense and defense had reversed, and he had become the apprentice?
He Jinbo asked, "Hey, Xiao Yang, what university did you graduate from?"

"Annan City Polytechnic Institute".

Yang Jinwen answered honestly that it was written on his resume and he couldn't fake it.

"I've loved math since I was a child, and I enjoy reasoning and verification. Solving a crime is similar to solving a math problem: make bold assumptions and carefully verify them!"

"Hmm, not bad." He Jinbo looked at the four whiteboards and couldn't find any fault with them.

He covered his mouth and said, "Oh, my tooth hurts. You guys discuss this first, I'll go to the forensic lab. We have a new forensic doctor here today, I'll go and fetch him."

He Jinbo didn't want to stay there at all and was going out for some fresh air.

Zheng Kang also felt awkward and needed to calm down, so he followed him out and closed the door behind him.

The two of them came out and looked at each other.

"Old Zheng, don't you think this kid is suspicious?"

"I'm wondering the same thing. How can a security officer at a steel factory be better at solving cases than us?"

He Jinbo continued to press, "I think... do you think I'm right?"

This guy wanted to be a cop, so he killed someone, pretended to be the person who reported the crime, and then used that as an opportunity to climb the social ladder and get the job. Otherwise, there's no way to explain this, right?

Zheng Kang shook his head: "It's unlikely. Isn't this just a mouse entering a cat's nest? How dare he? Can't you tell if he's a suspect?"
Besides, Director Lu said this kid will start working after the summer vacation, so he doesn't need to do this kind of thing.

He Jinbo stroked his chin: "Could it be that we've really encountered a criminal investigation genius?" Zheng Kang pondered: "It's not impossible! We can't be too suspicious and doubt our own comrades."

Don't forget, old man Ma Yulin, he never went to school, but just by herding sheep, he managed to figure out a set of criminal investigation techniques.

"Come on, Yang Jinwen is your apprentice, that's why you say that." He Jinbo was a little jealous.

“Apprentice?” Zheng Kang sneered, “If this continues, I’ll have to become his apprentice.”

"Alright, alright, I'm going to the forensic lab. Forensic pathologist Wen is a top student transferred from the city bureau. She heard about the dismemberment case and went to the funeral home last night to perform an autopsy. I'll go ask her about the situation."

Zheng Kang nodded: "Then I'll go to the technical department to see if any new evidence has been found at the scene where the body was dumped."

The two wandered around for half an hour, and then met up again outside the conference room.

Zheng Kang was surprised to see the young woman following behind He Jinbo.

"Who is this?"

He Jinbo stepped aside: "Old Zheng, let me introduce you. This is a forensic doctor who was just transferred from the Municipal Bureau. She's also a top student. She's Wen Ling, the forensic doctor."

"Wen Ling, this is Zheng Kang, the deputy captain of our Major Crimes Unit. You can call him Uncle Zheng."

"Hello, Uncle Zheng," Wen Ling greeted him with a smile.

"Hello……"

Zheng Kang took a breath. This girl was too beautiful. He could imagine what the young men from the Major Crimes Unit would think in a moment.

He Jinbo winked at him, as if to say the same thing.

He called out and pushed open the door: "Let's have a meeting first, we're going to be busy today."

The three people entered the house and were immediately dumbfounded when they saw what was inside.

There were more than a dozen members of the Major Crimes Unit, some standing, some sitting in chairs, and some with half their buttocks resting on the conference table.

Everyone held a pen and notebook, their faces serious, listening attentively and taking notes.

Yang Jinwen stood in front of the four whiteboards and said loudly, "Everyone has seen the dismemberment at the scene, so we will not discuss the dismemberment of the limbs and neck."

Take dismemberment between the chest cavity and the waist as an example. The waist circumference of an adult is difficult to cut with ordinary tools.

However, the incision on the victim's abdomen was relatively clean, indicating that the number of cuts was very small.

This indicates that the killer used at least two or three tools to dismember the body; I suspect an axe was definitely present.

"Let's put aside the dismemberment tools for now and first determine two things."

First, according to Huang Cuicui's husband's statement, she left home at 6 p.m. on May 30th. After that, where did she go? Who did she see? These questions need to be investigated one by one!

Secondly, after the body was found at the dumping site, we found only body parts, but no clothes belonging to Huang Cuicui. We asked someone to confirm what clothes she was wearing when she left home.

The murderer must have disposed of the clothes, either by burning them, throwing them in the trash, or burying them.

The murderer disposed of the body carelessly, not even hiding the victim's head, indicating that the victim's clothes were not carefully disposed of either.

We'll trace the path from the body disposal site outwards, searching through trash cans to see if we can find any clues.

Finding the victim's clothing allows us to determine the approximate area of ​​the dismemberment scene.

The most important point is the scene of Huang Cuicui's murder and dismemberment.

If we still can't find the person, we'll go to the scene!

If you kill someone and dismember the victim, besides the murder weapon, what else would you need?
