Chapter 553 Hell on Earth

"Where's the hair?"

In the case handling hall, Chen Yi asked while taking the documents handed over by the police.

The police officer replied: "The hair belongs to Kou Chaoyi."

Chen Yi flipped through the pages. The report contained detailed processes and not just results. The principle of DAN detection is to compare various sites to determine whether they are the same. Nowadays, the technology is very mature.

"How long does it take for blood to clot?" Chen Yi asked again.

Police officer: "The initial judgment is several years old. We need to detect the growth of microorganisms for further confirmation."

There is of course a difference between a blood stain that has been clotting for several years and a blood stain that has been clotting for a few days. The main differences lie in the appearance of the blood, color changes, and possible microbial growth.

Fresh blood is bright red. As time goes by, the blood will gradually oxidize, and the color will change from bright red to dark red, and eventually may turn into brown or gray-brown.

This process will be accelerated in sunlight.

The blood stains found in Guan Xinmei's dormitory had obviously turned brown, and the areas exposed to direct sunlight had turned gray, so they were definitely not left recently.

As for the growth of microorganisms mentioned by the police, it is relatively simple. Blood is rich in nutrients. If the blood is not completely dried within a short period of time, microorganisms may breed.

When the blood has dried for more than half a year, the nutrients in it will be greatly reduced, which is not conducive to the growth of microorganisms.

Therefore, the number of viruses or bacteria in blood that has been dried for more than half a year is relatively small, and may even have lost activity.

"Go." Chen Yi waved his hand.

"Yes." The police officer turned around and prepared to leave.

"Wait a minute." At this time, Chen Yi suddenly stopped him, picked up the report in his hand and said, "The blood does not belong to Guan Xinmei. Is it possible that it is a relative of Guan Xinmei?"

"Relative?" The police officer was stunned for a moment, and quickly replied: "If we are related, we need to re-evaluate it, but it is definitely not a parent-child relationship. Do we need to do a kinship test, Captain Chen?"

Chen Yi thought for a while and nodded to let the other party implement it.

In fact, it was not necessary. He asked about family relationships because he suddenly thought of Guan Xinmei's mother.

This woman is currently in a state of silence.

It's always right to be skeptical.

What if?

"It's not Guan Xinmei's mother..."

Chen Yi stood up with the documents and entered the forensic room.

The inspection of Guan Xinmei was over. Fang Shuyu had written the report. When Chen Yi came in, she handed the report over without saying anything and let Chen Yi read it by himself.

Chen Yi thought he had made an important discovery, but after reading it, he actually didn't. Guan Xinmei didn't have any scars on her body, but... she was no longer a virgin.

Guan Xinmei had sex with men.

"She has a boyfriend?" Fang Shuyu asked.

Chen Yi shook his head: "I haven't heard of it, I'll go find out."

Leaving the forensic room, she came to the room where Guan Xinmei was.

At this time, Guan Xinmei was sitting on the sofa obediently, without taking a sip of the water in front of her. This might be her first time at the Public Security Bureau, and her nervousness and fear were obvious on her face.

Chen Yi sat down, put the test report on the table, and said, "Guan Xinmei, the blood stains in the dormitory are not yours, why did you lie?"

This time Guan Xinmei was prepared and answered quickly: "It's not mine? Then I don't know. My hand was indeed injured at that time."

Chen Yi knew what she was thinking.

The dormitory is a temporary residence. What does the blood stains found in it have to do with the students living there? I don’t know that’s normal.

But her acting skills aren't very good and her logic doesn't make sense, and she definitely knows that.

Just because of some reasons, I don't want to tell the truth.

What's the reason? What is she worried about?

It is difficult to infer without knowing the owner of the blood at the moment. Judging from the interview results given by Qin Fei, the college student named Wu Yuehan and Guan Xinmei should have been harmed by Kou Chaoyi.

Wu Yuehan stopped at obscenity, what about Guan Xinmei?

Has it succeeded?

Kou Chaoyi's private hair was found in the dormitory. Guan Xinmei was not a virgin, so the probability of success was very high.

She has never chosen to graduate and go to university. The reason given was that she wanted to take an undergraduate degree. Is it possible that she didn't want to take an undergraduate degree, but was unable to leave under Kou Chaoyi's pressure?

Her mother was nowhere to be found, and no one could support Guan Xinmei. She did not dare to resist and was unable to resist.

"Do you have a boyfriend?" Chen Yi asked this question.

Guan Xinmei denied: "No."

Chen Yi: "Then who did you have sex with?"

Guan Xinmei was stunned. Then she realized what the beautiful forensic doctor was examining just now, and she lowered her head and fell silent.

Chen Yi's voice was soft: "Classmate Guan Xinmei, this is the Public Security Bureau. I am Chen Yi, the captain of the criminal investigation detachment. You can tell me anything you want. I promise you that you will never be harmed in any way. People who have made mistakes, They will also get the punishment they deserve.”

Guan Xinmei's shoulders shook, her head drooped lower, and her expression could not be seen.

Chen Yi continued: "If you are still afraid, you can get to know me. Chen Yi's name can be found online.

All you need to know is that there is absolutely no way anyone can get away with it here.

Speak out boldly about what happened. "

Guan Xinmei's shoulders shook more frequently, as if she was crying.

Chen Yi stood up and tentatively took out a few tissues and handed them over. Guan Xinmei took them and was wiping her eyes.

Sitting back in his original position, Chen Yi stopped talking and waited quietly.

A few minutes later, Guan Xinmei stopped crying, held the wet tissue in her hand, and slowly raised her head.

The red eyes met Chen Yi's.

Chen Yi was looking forward to her next words.

"Captain Chen..." Guan Xinmei said softly, "Nothing happened. I really don't know whose bloodstains are in the dormitory."

Chen Yi's face darkened slightly, not against Guan Xinmei, but against the person behind her.

This person should be Kou Chaoyi.

What happened in Guan Xinmei's dormitory? Why did she hide it?

From her crying just now, Guan Xinmei must have a huge grievance in her heart, but she insisted on not choosing to speak out.

Even when she arrived at the Municipal Bureau, even in the face of the persuasion of the Criminal Investigation Detachment Captain, she did not waver at all.

"Think about it again. There is a computer over there. You can search whatever you want. Repeat again, my name is Chen Yi, Erdong Chen, the more the better."

After that, he left the room.

Guan Xinmei sat there quietly and lowered her head again.

"Jiang Jie."

Chen Yi waved and called Jiang Xiaoxin over, and told her to try to make friends with Guan Xinmei. The ultimate goal was to make Guan Xinmei trust the police and tell them everything she knew.

It might not work, but you need to try. Women are easier to communicate with each other.

As a computer major, Jiang Xiaoxin has never participated in an arrest operation. She is relatively friendly in temperament. Other female police officers are a little more serious, which makes people feel resistant.

"Okay, I'll try my best." Jiang Xiaoxin entered the room.

Afterwards, Chen Yi went to see Kou Chaoyi.

There's no need to talk about Kou Chaoyi. He didn't know anything. If you want to pry something out of him, you might as well go to Guan Xinmei.

"Captain Chen, I really don't know what's going on. Whose bloodstain is that?" After a few questions, Kou Chaoyi was a little anxious and started to ask back.

Chen Yi didn't answer and talked about Guan Xinmei.

Single dormitory, such a privilege, why? She is not a relative of a school leader.

I have to associate it with words like [A Beautiful Girl Hidden in a Golden House] and [Two Qiaos Locked in a Copper Sparrow in Spring].

Kou Chaoyi's answer was that Guan Xinmei was an "old man" in the school and had studied for several years just to get a good undergraduate degree. There was a generation gap between the ages of three. Guan Xinmei lived with other younger students and could not handle the relationship well.

If Guan Xinmei could get good grades, it would be a great help to the students' publicity, so she was given a separate dormitory so that she could study hard.

Reasonable, but far-fetched.

"Why is there your hair in her dormitory? Do you go there often?" Chen Yi said.

Kou Chaoyi nodded: "I go there often. Guan Xinmei is a seed player in the college entrance examination. As the principal, of course I have to care about it. The hair that Captain Chen said...may have fallen accidentally. This is normal. Don't we often lose hair in our daily lives?"

Chen Yi stared at him: "I'm not talking about hair."

Kou Chaoyi understood immediately and said calmly: "That's normal. Captain Chen is a man. Don't you have similar experiences?"

Chen Yi did not comment.

As long as there is no evidence, no evidence, and both parties deny this kind of thing, there will be no conclusion.

What we need to do now is to determine the owner of the blood as soon as possible.

"Captain Chen, can Guan Xinmei and I leave today?" Kou Chaoyi asked.

Chen Yi stood up: "Let's talk about it later."

He left the room.

In the meeting room, everyone sat down to discuss the focus of the next investigation of this case.

There are only two things.

First, whose bloodstains are in Guan Xinmei's dormitory, how did she get injured, and whether she is alive or dead.

Second, what did Kou Chaoyi do to Guan Xinmei.

The parties themselves did not tell the truth, which instantly increased the difficulty of this case.

"Since it is in the school, it should be a student, right? It will take a lot of work to investigate." Qin Fei said.

A large amount of work does not mean that we will not investigate. It does not rule out the possibility of extracting DNA from all students, including graduates, for comparison.

Judging from the amount of bleeding, the injuries are definitely not light, including death.

Chen Yi tapped the table gently and said, "Go through the missing cases and see if any students or teachers of Qingshi have disappeared in recent years, or people who have a relationship with students or teachers."

The police officer took notes and checked them immediately after the meeting.

"Why don't you tell the truth?" After an order was issued, Chen Yi raised his hand and rubbed his eyebrows.

Qin Fei looked around and saw that no one gave any opinions. He hesitated and said, "Captain Chen, is she protecting Kou Chaoyi? Although it's a bit outrageous, it's possible. At least it can explain the current situation."

Chen Yi was still rubbing, and a voice sounded: "You want to say Stockholm syndrome."

Qin Fei: "Yes."

Stockholm syndrome is a rare mental illness.

The main manifestation is that when the victim faces extreme threats, he will have emotional identification with the perpetrator and even form a harmonious relationship.

This mental illness is related to the body's automatic protection mechanism. If you can't resist, you will obey, and then you will develop a sense of worship of the strong, and serious ones will have emotional dependence.

In short, the psychology is distorted, liking is a deformed liking, and love is a deformed love.

Chen Yi thought about this possibility. If it is true, it will be troublesome. He needs to be treated first and then asked.

"How about finding a professional psychologist to judge? Sister Xue is not here." Qin Fei spoke up immediately. He felt that the possibility was still not small.

There are psychological counselors in the bureau. The most qualified one is Sister Xue mentioned by Fang Shuyu before. She is a national second-level counselor.

Her usual work is to provide psychological health training, counseling education, group counseling, crisis intervention, etc. for police officers and the public. She is also responsible for providing a 24-hour psychological service hotline for the psychological team.

But she asked for leave.

I heard that there was something wrong at home, emotionally, and everyone speculated that her husband was cheating on her.

Chen Yi agreed: "It is indeed necessary. You don't need to worry about it. I will make arrangements."

Qin Fei nodded: "Okay, are you still looking for Guan Xinmei's mother?"

"Let it go first. The top priority is to find the owner of the blood stain." After saying that, Chen Yi looked at Lu Yongqiang who was sitting on the right hand side. "Brother Qiang, in this case, you can take someone to fully investigate Kou Chaoyi's office to see if it can be found." Find some useful clues and search warrant later.

By the way, check the walls carefully to prevent the existence of secret rooms. "

Kou Chaoyi's problem is huge, and now the investigation will cover a wider area. As Kou Chaoyi's second home in the school, the office is very private, and clues may be found.

Lu Yongqiang accepted the order: "Yes!"

After the meeting, Chen Yi called Shi Xin's phone number and asked the other party how the search for Du Xun was going.

"There is no progress yet." He Xin said on the phone, "Almost 80% of the Internet cafes have been found. The surveillance around the school has found no trace of Du Xun. There are too few remote surveillance in major places. Oh, by the way, last Sunday night At 10:34, Kou Chaoyi drove away from the school. "

Chen Yi: "Where have you been? Are you going home?"

Shi Xin: "It should be so. I saw it in the surveillance. There is no continuous tracking. Do I need to confirm?"

Chen Yi: "No need for now, I'll go ask him directly and go through all the Internet cafes as soon as possible."

Shi Xin: "Okay, if you still can't find her, I'll check the city's surveillance cameras, use facial recognition, and look for Guan Xinmei's mother."

Chen Yi hummed and hung up the phone.

…

Youth.

Lu Yongqiang led people into the school and came to Kou Chaoyi's office.

No door lock.

All technical investigators put on their shoe covers and gloves and entered the room to begin their investigation work.

If there are obvious suspicious traces, it is very easy to find the intervention of technical detectives. In just ten minutes, something has been harvested.

"Army!"

Hearing the shout, Lu Yongqiang, who was groping for the wall, subconsciously turned around and walked over quickly.

Squatting next to the sofa, he looked at the foot of the sofa pointed by his subordinate. Under the illumination of the trace light, there was a little fluorescence there that made the investigators nervous.

"Close the curtains, reagent!"

Lu Yongqiang gave the order and took a few steps back.

When the reagent is sprayed, blue-green fluorescence appears, and as the spray area expands, there is no interruption at all. The fluorescence keeps appearing, extending to two meters away from the sofa.

Because it had been wiped, the area was very wide, and a large amount of blue-green fluorescence rushed towards the face, beating wildly in the eyes of all trace inspection personnel, as if they were venting dust-laden grievances and roaring the long-lost truth.

"Continue!" Lu Yongqiang's eyes trembled.

There was no psychological preparation for the scene in front of him. After receiving Chen Yi's order, he thought he was just here for a casual look.

All trace inspections incorporate reagent spraying, because the fluorescence will gradually dissipate in thirty seconds, so they are very fast.

Can't stop, can't stop at all.

On the floor, on the sofa, on the coffee table, on the wall...

The color depth caused by the concentration of iron ions can be seen in the form of splashing, throwing, dripping, wiping, dipping, dilution...

Lu Yongqiang took a breath of air. The shocking fluorescent blue flash was a bit dazzling for him. In so many years of working in the industry, he had never seen such a terrifying scene.

This is Kou Chaoyi's office, it's simply hell on earth.

"My mother, what...what's going on?"

After Lu Yongqiang came back to his senses, he immediately took out his mobile phone and dialed Chen Yi.
