Chapter 309: Perverted Serial Killer

During the interrogation, Jiang Yang thought of another group of students who were detained in the Dongjie Police Station for causing trouble in the mall, and they were also from No. 9 Middle School.

After questioning, he found that the leaders Fan Ming and Liang Wei were also the main forces bullying Bian Ruiyi.

He simply called Zhang Jianbai, who said that he would send the people over immediately.

Since then, several cases have been merged and subdivided.

So the police force was divided into two groups, one led by Jiang Yang, focusing on investigating the Bian Ruiyi case.

The other group followed Xiao Zhiwei to deal with the remaining No. 9 Middle School students.

Under the persuasion of the police, Bian Sui and Yang Shuyu returned to Bian's house to tidy up Bian Ruiyi's room, trying to find more clues.

After the arrangement was roughly done, Jiang Yang looked at the principal of No. 9 Middle School who had been waiting in the hall, "How long does the school usually keep the surveillance? Do you still have the footage from the Winter Games last year?"

"Of course not. Our school's surveillance footage is usually kept for three months."

Principal Zhu made a bitter face and said carefully: "Well, Officer Jiang, do you think it's okay not to report this matter first? The middle school entrance examination and the college entrance examination are coming soon. If it gets out of hand, it will have a bad impact..."

"Oh, you also know that the matter is serious? Are you scared now?"

Jiang Yang hates people who muddle through in normal times and fish in troubled waters when something goes wrong.

His eyes were too cold, and Principal Zhu shivered and walked away with his neck shrunk.

"Guo, go in and check the surveillance cameras. The ones on the street opposite the No. 9 Middle School and the ones at the nearby intersections. Anything that can capture the gate of the No. 9 Middle School and the roads on both sides is needed."

"Zhang Jianbai, come with me to the traffic police detachment. The CFMOTO 450SR was just launched last year. It's not difficult to check the owners of the licensed cars."

"By the way, Lin Yu and Xu Fei go to the CFMOTO store and check the purchase records."

After Jiang Yang calmly gave the order, he divided his forces into three groups to conduct the investigation.

On the way, the forensic doctor called.

The results of the appraisal were not optimistic.

"Preliminary appraisal shows that the deceased, Bian Ruiyi, had been violated before her death. There were severe soft tissue contusions in her private parts, bruises of varying degrees on her hands and feet, and slight bone fractures. However, because she fell from a building, some judgments may not be accurate. From the analysis of the traces, it can be roughly inferred that the injury occurred four to five hours ago. Unfortunately, no residual body fluids were found..."

With every word, Jiang Yang's heart dropped a little.

"...Based on my experience, the person who violated the deceased Bian Ruiyi is likely to have violent tendencies. Further verification will take some time."

"Thank you, Dr. Wen. Please notify me as soon as possible if there is any situation."

After hanging up the phone, Jiang Yang frowned.

Why did he feel that the forensic identification was familiar?

While telling Zhang Jianbai the preliminary identification results, Jiang Yang pondered.

"What are you thinking about, Brother Yang, we're already here."

Zhang Jianbai patted him on the back and turned to get out of the car.

"Do you feel weird?"

Jiang Yang couldn't help asking.

"What?"

Zhang Jianbai was puzzled.

"That's right, he committed suicide by jumping off the building and was violated before his death."

"I seem to have seen similar descriptions in other files."

Jiang Yang has an amazing memory and a photographic memory. As long as he has seen it, he will never forget it.

The two have already walked to the traffic police detachment.

He asked Zhang Jianbai to go in first, and he stood outside and called Qin Mingzhi who stayed in the bureau, asking him to help retrieve the Rongcheng files.

Search keywords: suicide, female student.

When Jiang Yang was investigating old cases, he had read thousands of files.

He skipped some of the cases that had been closed long ago, but he occasionally glanced at them.

Two or three minutes later, Qin Mingzhi said, "Two months ago, a senior female student jumped to her death in No. 2 Middle School. The case was concluded that the deceased had mild depression and committed suicide due to excessive pressure from the college entrance examination, and had nothing to do with others."

"But the identification results of the deceased are very similar to Bian Ruiyi."

"Both were subjected to sex and violence before death, and the locations of multiple contusions were similar."

"In addition, there were similar cases in No. 1 Middle School five months ago, Guilong Middle School half a year ago, Liming Middle School eight months ago, and No. 3 Middle School eleven months ago."

"City No. 1 High School is a key school in the city, No. 2 High School and Limin High School are both key schools in the district, Guilong High School is a private school, and No. 3 High School is a general high school. Several high schools are scattered all over Rongcheng City, both in the city center and in the suburbs, and there is no pattern for the time being. "

"However, the victims of these cases have one thing in common, all of them are female students, with good family conditions, but their parents rarely discipline them, and they all show signs of being violated before they died."

"And, they all committed suicide."

"Some jumped off the building, some cut their wrists, and some pierced their carotid arteries."

Qin Mingzhi finished speaking in one breath, and both sides of the phone were silent for a moment.

"Hey, Brother Yang?"

"Yes, I'm here."

Jiang Yang's hands hanging by his side clenched into fists, and the blue veins on his face were faintly popping.

If there is someone behind these cases, that guy must be a perverted murderer!

Moreover, the murderer's killing rhythm has a relatively stable frequency, and the objects he is looking for also have something in common.

This is a serial perverted murderer!

Before being discovered, in addition to these people, I don't know how many innocent female students he has killed!

[Ding! The host is investigating a serial murder case. Successful investigation will earn 8,000 points! 】

The system prompt brought Jiang Yang back to his senses.

He was so angry that he had no way to vent.

"Damn, you're a pervert, right? Wait until I catch you, and I'll let you know what a pervert is."

"Brother Yang? What are you talking about?"

Qin Mingzhi's hair stood up all over his body.

He seemed to have heard something incredible!

"Notify Captain Xiao and tell him that I'm applying for a merger of multiple cases! All cases of female students committing suicide will be re-investigated!"

"Ah? Oh, okay!"

Jiang Yang walked into the traffic police detachment with a dark face. The police inside saw that he looked unhappy and immediately stopped teasing him.

"Brother Yang, I found something!"

Zhang Jianbai greeted him excitedly, "There are a total of 139 CFMOTO 450SRs registered before November 26 last year."

"Fifty-two owners are men over 30 years old, and four are female owners."

"The rest are young boys over 18 years old and under 30 years old."

He handed the printed list to Jiang Yang and called up the surveillance cameras on the route near No. 9 Middle School.

It was hard not to find the person after all this trouble.

With a photographic memory and a three-year-old painting skill, Jiang Yang easily identified the suspect.

"Huh? So young, only 23 years old, the same age as you, Brother Yang."

Zhang Jianbai was surprised.

"Let's go back to the bureau first."

The two walked out quickly, one after the other, and the police from the traffic police detachment breathed a sigh of relief.

"Do you think Jiang Yang is particularly angry today?"

"Yes! He looked like he had eaten explosives when he came in just now. I didn't even dare to say hello to him!"

"Me too! I was scared."

"Who was so blind that he provoked him?"

"Do you need to ask? It must be a damn criminal!"
