It's going to be late.

Rebe International College.

Private colleges, red walls and green spaces, under the sunset, a British garden scenery.

It’s okay to have regular facilities such as basketball courts and stadiums, but the two actually passed by a golf course.

After parking the car, Zhao Lecheng watched from afar and exclaimed, "This is much more luxurious than our police officer school."

"How much does your school cost?" Zhou Nan got off the car and walked towards the scene.

Zhao Lecheng hurriedly followed, "Four thousand nine."

"So what's so similar..." Zhou Nan had already seen the cordon while speaking.

"Ah? What do you mean is that the tuition here is very expensive?" Zhao Lecheng was full of curiosity.

"Boss," Lao Zuo, who came up to answer Xiao Zhao's doubts, "Take back the word "My" and start at 20 w, and the tuition fee only accounts for a small amount."

Zhao Lecheng was shocked, "Twenty-hundred thousand! With the accommodation and meals, it will cost no one million in four years? I can't afford to sell me!"

Lao Zuo shook his head, "Everyone said that tuition fees only account for a small part, how can one million be handled?"

Xiao Zhao was puzzled, "Is accommodation and food more expensive than tuition?"

"That's not," Lao Zuo Xunshi, "You have to think about who are studying here? For example, it's not too much to learn horse riding in an interest class? It's gone for 300,000 or 500,000 a year. The child is on summer vacation, and it's not too much to go abroad to experience a summer camp? It's another 200,000 or 300,000 or 300,000 or so, you taste it..."

"Hiss," Zhao Lecheng took a breath, "I dare not think or think, as if there is a world across. That Mr. Jiang is really rich."

Finally it was Lao Zuo's turn to draw a question mark, "What is Mr. Jiang?"

Zhou Nan, "...". I don't want to mention it, why do you think it's so intimate?

Without wanting to listen to the two people's muttering, Zhou Nan accelerated his pace to the scene.

There is an experimental building in front of me. Because it is summer vacation, there are few students on campus and no onlookers have occurred, the scene is well preserved.

At this time, the detachment personnel who arrived in advance were busy taking photos and collecting evidence.

The moment he saw the corpse from afar, Zhou Nan felt a lot of emotion, so what day is today? Should he be allowed to fully experience the sense of reincarnation?

It is normal to have grass and trees on campuses with extremely high greening rates.

Around the experimental building, there is a circle of green belts about 3-4 meters wide. The landing point of the body is on the brick floor on the outer edge of the green belt.

"Cross Weekly."

After a while watching, he took the headband handed over by the team members on the scene. After putting it on, Zhou Nan approached it calmly and leaned over to check it out.

Finally satisfied with the curiosity of gossip, Lao Zuo also caught up at this time, coughed, as if he wanted to say something.

He didn't look back at all. Zhou Nanweibu seemed to have raised his hand to stop him, and pointed at the dead, "Tell the serious matter."

OK.

Lao Zuo's face finally turned aside, "The deceased Qi Chujin, 19 years old, a student at Ruibei International College. The reporter was a school security guard. He found an abnormality during a routine inspection. According to him, Qi Chujin had stopped breathing and was cold all over."

Zhou Nan raised his eyebrows, "So, there are no witnesses, and the specific time of death cannot be determined?"

Lao Zuo nodded, "The deceased's mother has contacted him. Cough, because she was too excited, she has been arranged to be in the administrative building for guidance and comfort."

As long as I am not embarrassed, what is embarrassing is the spirit of others. Zhou Nan continued to ask the forensic doctor on the scene as if nothing had happened, "Can you determine the cause of death?"

The middle-aged glasses uncle said tactfully, "It can be basically confirmed that he fell from the building before his death. The deceased was lying on his prone position, except for the head, there were no serious external trauma, and there were multiple fractures all over his body. It was initially determined that he fell from the building and died. The specific cause of death must be accurately determined after dissection."

Zhou Nan nodded, there was nothing difficult to understand.

As the name suggests, falling off a building was that people were still alive before falling off.

Accurately determining whether to fall off a building during death or fall after death is of great significance to investigating a falling off a building case.

Generally speaking, it can be determined whether you fall from a building during your lifetime based on the "life reaction" of the corpse wound, that is, the state of blood clotting.

We all know that because humans have a self-healing function, people bleed when they are alive, platelets will cause blood to coagulate and achieve bleeding, and this phenomenon will not occur after death.

In addition, it can also be judged by the location of the fracture. As long as you fall down when you are alive, the reaction force against the ground will appear at the moment when you land. This is the instinctive reaction of the human body and cannot be controlled and avoided. The consequence of this is that the fracture occurs at the large joints of the bone.

People who fall off the building after death lose this instinctive reaction. The fractured areas will not be limited to the joints, and will mostly be distributed irregularly according to the impact location.

The characterization of the case will naturally not be the same if it falls before death or after death.

Falling down a building during his lifetime can be either suicide or hell. However, falling down a building after death can be seen to be only one possibility, and hell will be left behind after hell.

So at present, the death of Qi, Chu and Jin may be both suicide and the possibility of homicide cannot be ruled out.

It looks like nonsense? But isn’t criminal investigation work just to rigorously eliminate these “nons” one by one and finally get the truth?

He looked up at the laboratory building and Zhou Nan said, "I'll go up and take a look."

After all, he was not a newbie two months ago. Not only did he not dare to look at the body, he had not even walked through the scene of the incident, but he finally solved the case. The lucky value was really full.

The interior of the experimental building is more low-key than the outside. After all, it is the school. No matter how rich you have, you can't eat the magnificent magnificent fruit.

But... they have an elevator.

The three of them took the elevator and arrived at the top floor effortlessly.

Lao Zuo held a small notebook and introduced, "I just saw this here. I found a pair of shoe prints on the edge of the rooftop. Apart from that, there were no special traces. Unfortunately, the roof of this experimental building was not under surveillance, otherwise it would be simple."

The rooftop has a wide view. Looking around, the lawns on the golf course are green and charming.

"Here," Lao Zuo pointed at Zhou Nan's position on the pair of shoe prints.

Fortunately, there was no strong wind today, otherwise this layer of floating soil with shoe prints would be difficult to keep.

Zhou Nan walked over and looked carefully, then looked downstairs, and the location corresponded to the corresponding position. He turned around the rooftop again, and it seemed casual, but it had actually brought the scene of the rooftop into his mind one by one.

Without witnesses, it means that there is no aunt. Lao Zuo’s “utility” has been reduced to a minimum, but it does not prevent Zhou Nan from asking, “Do you think it’s suicide or killing him?”

Lao Zuo closed the book, "I can't be sure of this, but no matter which one, there is something that makes no sense."

Zhao Lecheng scratched his head, "Why can't it make sense?"

"Drop!"

Zhou Nan and Lao Zuo rarely speak in unison.

Xiao Zhao's desire to seek further advice was interrupted by a crying sound from afar.

"My son is dead, why can't I see you? Let me go!"

Ms. Jiang, here.
Chapter completed!
