As spring is in full bloom, buds grow on the trees beside the road, and new leaves are about to emerge.

The weather forecast says that the temperature across the country has generally recovered in the past two days, and some areas in the south have reached 20 degrees.

Although Beijing City does not have such a turbulent warmth, it is also sunny and very comfortable.

According to convention, after the Spring Festival, the time for personnel changes in the city hall. In order to make up for the shortage of criminal investigation personnel, on the basis of four serious crime groups, the city hall has formed five and six serious crime groups.

To form a new group, one will naturally draw personnel from the old group. Wu Cuo's serious case group was the first to be hit and two generals were removed.

Fortunately, a new batch of intern college students were assigned to the Criminal Investigation Major of Public Security University.

As soon as the students arrived, they were divided up by six serious crime groups.

Early in the morning, Wu Cuo browed.

"Why, Lao Wu, are you bullying?" Zhang Xuxinger, the forensic department, joked with a teacup.

"The only girl is divided into us."

"This is not very good. The organization sees that your group is almost becoming Shaolin Temple. I send a girl to let you quench your thirst. You have to thank the organization for your good intentions."

"Bah! I hope the plum quenches thirst! Why didn't you notice it long ago? Old Xu, you are just an old hooligan!"

"I don't dare to be it."

"You also know that criminal investigation work always takes place in the murder scene, and it is possible to fight face to face with the criminals. Is this a girl's family capable of? Also, if we go to another place to handle the case, it is not a problem for us masters to sleep in the open, and it is too inconvenient to bring a girl."

"You can endure hardships? How do you know that other girls are not good? Look, the new group of people may not be worse than you."

The two chatted without saying a word and arrived at the door of the office of the group Serious Case.

When the new two people saw that the team leader Wu Cuo had arrived, they quickly stood up and greeted him.

Wu Cuo signaled them to sit down without having to do these false gifts, and introduced to Xu Xinger: "This, Bai Chao, the newly assigned college student."

Bai Chao was wearing a pair of circular glasses, a big man who was nearly 1.9 meters tall, and his police uniform exposed a piece of ankle, which seemed to shrink.

"Who sent you the police uniform? It's too inappropriate. I'll take you to find a logistics company later." Wu Cuo said.

Bai Chao scratched his head, thanked Wu Cuo, and smiled at Xu Xinger honestly, "Just call me Xiaobai."

Wu Cuo continued to introduce: "This, Zhang Minghui, the new girl."

Zhang Minghui had a smooth ponytail, and her whole body was as capable as her name. She smiled at Xu Xinger and revealed her two dimples, "Just call me Minghui."

Finally, Wu Cuo introduced to the two: "This is Chief Xu of Forensics Department, our senior, and many cases are solved by relying on Section Xu's professional knowledge. Our two departments cooperate the most closely and we must establish good relationships with colleagues in the forensics Department in the future."

"Who are you going to have a good relationship with? You are here early in the morning." Yan Ruyu walked in and said to Wu: "Old Wu, is there a case? Bored."

Wu Cuo was not angry when his words were interrupted. He grabbed Yan Ruyu and introduced to Xiaobai and Minghui: "This is our group of non-staff members, Yan Ruyu, you can call him Xiaoyuzi."

"Bah! You are just Xiao Yuzi, what's wrong with you working in the palace?" Yan Ruyu introduced himself, "Just call me Lao Yan. When your team leader doesn't have enough IQ, I will save the situation."

Before he finished speaking, Yan Ruyu was pulled aside by Wu Cuo, "Old Yan, there is a case that is quite strange. You have to check it with me."

When he heard that there was a case, Yan Ruyu could not care about anything else and signaled Wu Cuo to continue.

"It was a mystery reported by the police station below." Wu Cuo said, and greeted Xiaobai and Minghui as well.

The two newcomers rushed forward, and for them everything was fresh and attractive.

Wu Cuo continued: "Last night, 110 received a call from the police, and the person who called the police claimed that he had seen the murder with his own eyes."

"murder?"

"Well. According to the police report, a murder occurred in the Baopai factory, and one person pushed the other down from the building. A few minutes later, the police station in the district where the Baopai factory was located received a report saying that someone jumped off the building."

"Baopai, a very famous mobile phone manufacturer, almost all well-known mobile phone brands are assembled from there." Xiaobai said.

Minghui added: "Yes, because of over-squeezing employees, the work pressure is too great. In the past two years, 13 jumps occurred in the building, which was called Baopai 13 jumps online. I heard that the rectification has been made in the past two years. Is the rectification false and the whitewashing true?"

"Don't rush to draw conclusions first. We are criminal police, not fortune telling immortals. Let's go to the scene to take a look."

Minghui stuck out his tongue and followed Yan Ruyu and Wu Cuo and walked out.

The four of them were riding in the same car, Wu drove the car at the same time, Yan Ruyu was in the co-pilot position, and Xiaobai and Minghui were sitting in the back seat.

As soon as the car started, Xiaobai took out a cigarette and took the initiative to hand it to Yan Ruyu and Wu Cuo. Minghui also actively said: "Senior, let's talk about the case you solved before, let's learn."

It can be seen that the two newcomers are trying to get closer to their seniors.

Wu mistook Yan Ruyu beside him. As soon as Minghui spoke, the guy started to close his eyes and rest without any intention of answering her.

That's right, when he was brought into the gang, Yan Ruyu once said that he would ignore anything other than solving cases.

There is no way, I can’t expect people with strong abilities to have a good temper.

Wu drove the car and thought for a while, and asked the two young men: "Why are you doing this?"

Minghui said, "I can't say why, I have liked it since I was a child."

"Civil servants have welfare housing, and they can solve the household registration problem." Xiaobai felt sorry for his words and said embarrassedly: "Am I too realistic?"

"It's good to be realistic, I like to deal with real people," this time, Yan Ruyu answered Xiaobai, "People always have to have some goals, especially real goals, otherwise there will be no motivation to work."

After saying that, Yan Ruyu continued to close her eyes and rest.

Wu Cuo thought for a little while and said to the two: "Most of our jobs are for the dead and we will ask for an explanation for those who die inexplicably. Therefore, it is enough to be willing to please and flatter anyone, just be worthy of your conscience."

The two people in the back seat looked at each other, obviously feeling something in their hearts.

Wu Cuo continued: "Take today's case as an example, we will go to investigate the scene, with the purpose of restoring the situation at the time of the incident and judging whether the conclusion of suicide is doubtful."

Baopai Factory, this is a huge industrial park, covering an area of ​​about 7,000 acres.

As soon as he entered the park, Xiaobai introduced: "As a global OEM giant, Baopai has factories in many provinces in China. The factory area here is not very large, but there are exclusive supermarkets, restaurants, and even bus lines inside."

Several people showed their IDs, and as soon as they entered the gate, a factory security guard invited several people to get on the electric car.

The car was shuttled through the factory buildings and drove for a long time, and finally arrived at the building where something happened.

There are 12 floors on the ground of the building. The first floor is the assembly line for mobile phone assembly, and the second floor is all administrative office areas.

On a concrete floor in front of the building, there are eye-catching human-shaped marks, outlining the last posture of the deceased staying in the world.

The blood stains around the human figure were not dry, and they looked out of place with the person who was in a hurry to go in and out of the building.

No one would look at the bloodstains more. Here, jumping off the building seems to have become the norm.

"Go to the top floor and have a look."

The top floor platform is very empty, and there is nothing else except the towering elevator equipment box.

There is a half-person-high wall around it, which can prevent danger.

A policeman from the local police station was on duty on the top floor. When he saw Wu Cuo and others, he stepped forward and saluted and introduced: "A few are comrades from the city hall? We have conducted a preliminary investigation of the scene. The deceased was named Tian Xiaofang. There was no trace of struggle, fighting or dragging on the scene. It was initially judged that he was suicide."

"What is the cause of suicide?" Wu Cuo asked.

"This deceased is a middle-level manager. There is always pressure to work in such a large factory. In addition, my husband has recently divorced her, so it's normal that he can't think about it."

Wu Cuo did not refute, but directly took the preliminary investigation record from the police.

He knew that there were many such people in the police force, and everyone was adults, so no one could expect to change anyone.

If that's the case, why bother playing the piano against the cow?

"Leave the next thing to us."

What is rare is that Minghui and Xiaobai did not complain, but quickly put on their shoe covers and gloves, starting from the only entrance and exit of the rooftop, they inspected the wall where the deceased fell from the building bit by bit.

Such a carpet-style search is not efficient, but it is better to be able to discover details.

Minghui also checked the ground and said to the security guard: "Uncle, do you have surveillance cameras in your building? Can you take a picture of who came to the rooftop last night?"

"There are surveillance monitors on the elevator. You can take the elevator to the top floor and take the footage. If you walk the stairs, you may not be able to take pictures."

Wu Cuo went directly to the wall where the deceased fell from the building and leaned over and looked down.

Yan Ruyu also came over and grabbed Wu Cuo's belt from his back to prevent him from falling.

"Are you looking for that trace?"

"Yes, that key evidence that can distinguish whether it is suicide or homicide."

Sure enough, a few minutes later, Wu Cuo made a discovery.

He stretched out most of his body out of the wall with difficulty and took a few photos with his mobile phone.

"Look, that's it!"

From the photo, we can clearly see that there are three obvious scratches on the coating on the outside of the fence, and the scratches are from top to bottom and very new.

"Is this the nail mark of the deceased?" Xiaobai asked.

“No, the spacing between nail prints will be narrower.”

"So this?"

"It's more like a scratch left by a ring," Wu Cuo found a photo of the deceased from the preliminary investigation record. On the photo, the deceased was wearing a gold ring with a middle finger in his left hand. "I'm now in touch with Lao Xu, I can have an autopsy. I must seize the time to intercept the body from the funeral home. If cremation is made, it will be troublesome."

The two intern criminal police obviously did not understand the key, but they did not dare to disturb Wu Cuo and Xu Xinger's call.

Yan Ruyu rarely explained patiently: "The scratches indicate that the deceased fell off the building, just like Old Wu's posture, with his head facing down, and he struggled briefly. She once pressed the outer periphery of the wall with her hand to leverage her strength, trying to push herself up.

Think about it, if it falls down simply and quickly, even if the ring scratches are left, there may only be one, and there is not enough time to leave three scratches at the same height."

The two understood the principle, and Minghui quickly asked again: "But, maybe the deceased was pushed down and struggled, or maybe she regretted it as soon as she jumped out, so she saved herself. The scratches cannot prove that he killed him!"

"This question is good," Wu Cuo took over the conversation and said, "However, we don't have to determine that it was a homicide. As long as the conclusion of suicide is doubtful, we should investigate until all doubts are eliminated."
