crime scene

Su Nian rarely agreed with Chu Duanyu's reasoning, he nodded and continued, "I have seen the school's surveillance cameras, which are distributed in teaching buildings, dormitory buildings, playgrounds, cafeterias, leisure and entertainment places like rockery groves, and There was no surveillance video installed."

"In this way, Xuanzi's investigation can actually be stopped. The suspect knows the school's terrain well, does not come and go without attention, and has a certain understanding of the victim. He has a certain amount of free time, a stable job, and a member of the upper class. The bosses don't have time to do this." Xie Qian said, ready to take out his mobile phone to call Yang Wenxuan.

"Wait, Captain, what if it's a hired killer?"

Chu Duanyu stretched out his hand and covered Qianqian's cell phone. The hypothesis he put forward was not impossible, but he just ignored a series.

"No, because of the special nature of the murder weapon, the killer will not go to great lengths to kill with a pencil, and if this is the special demand of the employer, it will greatly reduce the pleasure of killing the employer, and he will not do so."

Su Nian explained, and Chu Duanyu silently withdrew his hand, holding his chin with a look of melancholy, "Then the suspect should be someone near the school?"

Xi Qian and Su Nian nodded at the same time.At the other end of the corridor, Feng Li was hurrying over here, wiping the sweat all over his face. His expression was anxious, and his steps were fast. It seemed that he had encountered something difficult.

"Captain, the family members are making trouble again."

The No. 14 case happened on Monday. As of today’s No. 18 Friday, there has been no substantial progress in the case, and the family members of the victim are not to blame.

Xie Qian pointed to the bench, motioning for him to sit down first.

"What's going on with Chen Nian'an?" Xie Qian asked.

"Him? Photon stared at him all the time. He never left the dormitory." Feng Li replied.

All the existing clues can be checked. Although there are many suspicious points, there is no way to move forward.

This fucking... cold case?

After two days of decadence, on March 21, in the early morning of Monday, another murder case occurred in the school.

The location is still on the roof of the No. [-] girls' dormitory building. It was discovered and reported by the girls who came for morning jogging in the morning.

At the same time as last time, the police came to the scene to evacuate the crowd, pull the cordon, and conduct a preliminary investigation.

The same method of death, this time the victim became Du Yakun's roommate, the short-haired girl, who was also stabbed in the heart with a pencil and died.

"It's exactly the same as last time." Chu Duanyu said as he took off his mask, "The time of death is almost the same, but because the cordon was pulled over there, the point of falling from the building was changed to this side this time."

Serial killings.

This is a serial murder case. The two cases are almost identical. There is no need to submit any application, and they can be investigated directly.

With a cigarette in his mouth, Xi Qian didn't light it, and asked Sun Yaoguang vaguely, "Have you mastered the basic information of the deceased?"

"Go and get it vigorously."

"Let him hurry up."

"The deceased woman, 170 in length, thin body, ether reaction was found near the nose and mouth, this is the only difference from the first case." Chu Duanyu said, raised his leg and stepped out of the cordon.

Ether?

Su Nian turned around and left quickly, but Xie Qian called him several times behind but did not respond.

"Damn, why is this kid running around!"

Xie Qian dropped the cigarette he had been holding in his mouth to the ground, and hurriedly chased after him.

"where are you going?"

"chemistry lab."

As a clinical inhalable anesthetic, it is also strictly controlled in the laboratories of key universities. After investigation, it was found that there were fewer reagents in the incubator.

"Sure enough, they are from the school."

Zhang Yitian rushed over after hearing the news, searched for a long time on the glass bottle with a search light, shook his head and found nothing.

The teacher managing the chemical reagents was a little confused.

"What do you care, you don't even know if you don't have this thing!" Xie Qian yelled a little vented, and began to ask routinely, "Is there any suspicious person hanging around recently?"

The teacher thought about it for a while, then shook his head, "No."

"Did anything unusual happen?" Xie Qian continued to ask.

"Oh yes, about ten days ago, two days before school started, the school had a power outage at night."

Xie Qian subconsciously glanced at Su Nian, who shook his head.

Not lying.

"Then where were you last night?"

As soon as these words came out, the highly educated chemistry teacher immediately understood what Xi Qian meant.

After all, as the manager of these chemicals, it is more convenient for him to stick to the theft.

"I was at home last night. The surveillance video at the gate of my neighborhood can prove that there is also an old man walking his dog downstairs."

Xie Qian patted Yang Wenxuan next to him, signaling him not to be stunned, and continue to investigate quickly, while he himself pulled Su Nian out of the laboratory building.

On the walkie-talkie here, the policemen in the distance who planned to withdraw the team reported the situation to Xie Qian.

After getting a general understanding of the situation, Xie Qian asked them to go back first.

In the same school, there were two homicides in just one week, which can be confirmed as homicides. Moreover, the two deceased were in the same dormitory and the same method of death, which had to arouse the great attention of the school and the families of the victims.

There is also panic among the students.

There was still some time before the students got out of class for lunch, Xie Qian deliberately chose a time when there were few people and came to the cafeteria, intending to take Su Nian to eat first.

A woman not far away, wearing neat overalls, walked towards the dining table where the two of them were sitting.

Su Nian knew her, Vice President Jiang, so she put down her chopsticks and poked Qianqian who was opposite to tell him to turn around, then continued to eat with his head down.

"Excuse me, this is the captain, right?" The vice-principal smiled politely at Shang Qianqian's eyes that just turned his head.

Xie Qian also probably knew why she came, so he patted the seat next to him and continued eating, "Sit down and talk."

Vice-principal Jiang sat down politely, leaving a gap between him and Xie Qian, "Captain Xie, this case has had a great negative impact, and the school hopes to solve the case as soon as possible."

Xie Qian nodded, "You don't need to say, I also hope to solve the case as soon as possible."

"The school wants to know the latest developments in the case."

"That won't work, the investigation process of all cases is kept secret." Xie Qian refused, and put a marinated egg in the bowl into Su Nian's bowl.

Su Nian raised her eyes, looked at him quickly, and buried her head in eating again.

"That…"

"Don't talk about it, our police force will send more people to check around the school, and we will also cooperate with your school's security department to deploy defenses in the school to protect the safety of students 24 hours a day."

This is undoubtedly a big move, as long as manpower is arranged, it will definitely attract a lot of media to rush to expose it first.

The more difficult the environment, the more it can arouse the criminal's desire to commit crimes. Su Nian does not approve of it, but after thinking about it, the only way to do this at present is to give the school, family members and students an explanation.

Vice-principal Jiang also agreed with his proposal, and nodded in satisfaction, "Then I will trouble the captain to arrange everything. If you have any needs, please don't hesitate to contact the school for consultation."

Qianqian snorted, scooped up the last few noodles in the bowl, ate them, wiped his mouth with a napkin, "It's true, let's free up a few empty rooms for work."

"it is good."
