Detective: Open your eyes, I am handcuffed in the interrogation room

In the room, when Ren Dan's voice stopped, Chen Yi fell into deep thought.

It sounds okay, but I always feel that something is not quite right. It may be because some details need to be further clarified.

For example, Ding Yunjie.

Judging from Ren Dan's description, Jiang Lili, He Shan and herself have not changed much after a few years after graduation. Only Ding Yunjie has changed to a certain extent.

When I was in college, I was introverted, weak, and didn't know how to drink. But now I dare to go to bars until early in the morning and still be alone.

From He Shan's point of view, it is true that if Ding Yunjie was not drunk on the day of the incident, this would not have happened. But from the police's point of view, even if Ding Yunjie was not drunk that day, the suspect would still be looking for her. Other opportunities.

Can't run away.

"Did you make a party appointment one day in advance?" Chen Yi asked.

Ren Dan nodded: "Yes."

Chen Yi: "Then why does Ding Yunjie go to the bar to drink so late? Is it because she is in a bad mood or is it just a lifestyle habit?"

Ren Dan: "I don't know."

Chen Yi: "Didn't you ask?"

Ren Dan: "No."

It seems that I have to ask Ding Yunjie to figure out any unusual points, which may be the key to solving the case.

Having said that, the reason why He Shan is treated differently can be seen indirectly. Her personality is relatively strong and she is also outspoken.

It sounds good to be outspoken, but it sounds bad to be sharp-tongued, mean-tongued, and talk nonsense without knowing the occasion. This can easily offend people.

Ding Yunjie had just suffered a nightmare at that time. As a friend, he should comfort him immediately instead of adding salt to the wound.

Of course, this cannot be said to be that He Shan has a bad heart, that's just her personality. It can be heard that although He Shan is accusing, there is also concern in it, and she does not want to really see her friend suffer great harm, and her way of speaking is lacking.

Finally, Chen Yi talked about the lives of the four of them in college, including how they met, why they became good friends, what they had experienced together, and who they had met together.

The point is the shared experience of the four people.

There is no doubt that the suspect's crime target is clear. It cannot be such a coincidence. It must be someone that the four of them know together, who committed a crime against the four of them for a specific reason.

It doesn't have to be someone you know very well, just a casual acquaintance should be investigated.

Ren Dan said while recalling that it was basically normal trivial things in college, nothing special.

As for extracurricular activities, that is, eating, hiking, singing, playing script killing, etc., there have not been any impressive changes.

Chen Yi: "Have you ever played script killing with strangers?"

Ren Dan: "I've played it before. Script killing is very suitable for playing with strangers. It's quite interesting and has a stronger sense of puzzle solving."

Chen Yi: "Didn't anything special happen? For example, someone fell in love with you and asked for your contact information."

Ren Dan shook his head: "I don't remember it. We left after playing."

Chen Yi: "I didn't encounter anything special when I was mountain climbing. Did I meet special people?"

Ren Dan: "No, the place we went to is not a scenic spot. There are few people. That is the real mountain climbing."

Chen Yi recalled the file and found that the rope used to tie the victims was not a climbing nylon rope, but an ordinary fine hemp rope. This was true for all four victims.

Fine hemp rope is widely used and has many purchasing channels. It cannot be used as a direction for investigation or as a basis for inference unless there are new clues to correspond to it in the future.

"Tell me all the climbing places you have been to," Chen Yidao said.

Ren Dan: "Okay."

After finishing the questions, Chen Yi said goodbye and was about to leave. At this time, Ren Dan suddenly stopped him, seeming to remember some new situation.

"A man chased Ding Yunjie."

"Chasing Ding Yunjie?" Chen Yi turned around, "When."

Ren Dan: "I remember it was my sophomore year."

Chen Yi: "Then what?"

Ren Dan: "Then we felt that the man was unreliable and advised Ding Yunjie not to agree. By the way, it was He Shan who started it. She knew the boy. Anyway, his reputation was not very good."

Chen Yi: "What's the result?"

Ren Dan: "Ding Yunjie didn't have any opinions and refused after our persuasion. Unexpectedly, the man got a new girlfriend in an instant. It turned out that it was indeed unreliable. What He Shan said was right. Ding Yunjie was quite grateful to us." "

Chen Yi: "What's your name?"

Ren Dan: "Sorry, I forgot. You can ask Ding Yunjie or He Shan, they will definitely remember."

Chen Yi thought for a while, nodded and said, "Okay, we understand."

The pursuit failed because of the intervention of He Shan and the others, and He Shan was the initiator. To a certain extent, it does fit the facts of the case, but it is a bit outrageous.

It's just a chase and play between men and women in college. There is a vast forest between success and failure. There is really no need to commit four rape cases in a row and disfigure a person.

Besides, it’s been six or seven years since my sophomore year.

How insane would it take to do this? The possibility is extremely low.

Even though the possibility is low, you still have to go through it. Anyway, you already have the suspect's DNA and you can just compare it.

As long as the net is cast big enough, the fish will definitely be in the net.

After walking out of the company door, Zhuge Cong and the others were a little silent, feeling the difficulty of solving the case.

The revenge rape also involved four people. The scope was very small. It stands to reason that the victim should be able to think of who he had offended, but neither He Shan nor Ren Dan gave any important clues.

The suspects that He Shan thought of were eliminated, and the suspects that Ren Dan thought of were so outrageous that they could neither advance the case nor close it.

Several people were wondering if the four of them had been targeted by some pervert while they were out partying.

"It's not a stranger, right?" Lu Minghe said.

Chen Yi did not answer, and Zhuge Cong said: "If you are a stranger, why would you disfigure He Shan? Why should you leave DNA for the police? It doesn't make sense."

Lu Minghe hesitated: "After listening to Ren Dan's description, I think it makes sense."

oh?

Zhuge Cong and others looked over.

Lu Minghe: "Isn't He Shan the most powerful among the four? She is also very talkative. It is possible to anger the suspect."

After brainstorming, Zhuge Cong suddenly realized: "Yes, this makes sense."

He Shan was so venomous towards her friends, let alone a suspect. She might have cursed something that caused the suspect to lose his mind in anger and become extremely violent.

With teeth marks and disfigurement, one can only imagine the suspect's horrific state at that time.

Lu Minghe turned around and said, "What do you think, Captain Chen?"

Chen Yi knocked on the cigarette case in his hand but did not smoke, and said: "When discussing this issue, we need to pay attention to one detail, that is, whether the suspect brought a sharp weapon when committing the crime. He Shan's face was scratched by a sharp weapon."

"If he had been carrying a sharp weapon when he committed the crime, the reasonableness of the inference would be established. If he only brought a sharp weapon when he committed the crime against He Shan, the reasonableness of the inference would not be true."

"We have no way of knowing whether he brought it or not."

"But what Captain Lu said is logical. We can assume that the suspect always had a sharp weapon with him, but he just didn't use it when he committed the crime against Jiang Lili and others."

Lu Minghe: "People need a sense of security when committing crimes, and sharp weapons are the source of sense of security, so I think he should always carry them."

Chen Yi: "If that's true...it will be difficult to investigate. The suspect has no criminal record and there is a huge crowd."

Lu Minghe was silent, and it could be heard that Chen Yi temporarily disagreed with strangers committing crimes. From the data, the possibility of a person with no criminal record suddenly planning to commit a major crime against a stranger was very small.

It is quite rare for it to happen. The suspects in such cases basically have quite a lot of psychological problems and their motives are incredible.

Therefore, considering the probability, it is still an acquaintance who committed the crime.

Chen Yi looked at the time and said: "First check in the direction of an acquaintance, go to Ding Yunjie, call and make an appointment, Captain Lu, you personally take the fingerprint inspection to Ren Dan's house, check it carefully, try to be as comprehensive as possible, don't just stare at it The crime room."

When Ren Dan woke up, the suspect was already lying on top of him. Before that, there was no way to know whether the suspect had other behaviors or whether he was moving around the whole house, so he could not miss it.

Lu Minghe: "Okay."

…

Ding Yunjie lives in a rented house and is now an online novel writer. She writes in the rented house all day long and rarely goes out.

That's what she said on the phone.

According to the address given by Ding Yunjie, Chen Yi and others arrived at the cheap relocation community and stood at the door.

There was a pile of garbage bags on the ground, and takeaway packaging could be vaguely seen.

It seems that I rarely go out, and even when I eat, I order takeout.

Ding Yunjie is a local, but she doesn't know why she moved out and why her parents agreed.

Boom, boom, boom!

After knocking on the door three times, the door opened with the sound of footsteps, and Chen Yi saw Ding Yunjie in pajamas with a haggard look on her face.

She had just graduated a few years ago and was in her prime, the age to pursue her dreams, but the words youthful vitality could not be found on Ding Yunjie's face.

Her skin lost its luster and became pale, sallow and dull, as if shrouded in a layer of gray mist.

The dark circles under his eyes were severe, as if they were caused by staying up late too often. His eyes looked dull and hollow, and the drooping corners of his eyes revealed an indescribable sense of exhaustion.

Not to mention her hair, which was messy and unkempt. She probably hadn't taken care of it for several days.

Two words describe Ding Yunjie: decadent.

The only thing I can praise is that Ding Yunjie's face shape is very good. Although she wears glasses, she can still see the good proportion of her facial features. If she can dress up carefully, it will still be very good.

I don’t know if the other person became like this because of the impact of rape.

"Hello, my surname is Chen." Chen Yi showed a kind smile.

Ding Yunjie's face was expressionless, and he turned around to make room: "Come in."

When everyone walked in, the whole room was simply displayed. The furniture they saw was quite old, and some of the wall coverings were peeling off due to mold, which really affected their mood.

The living environment is average.

The rent for relocation housing is cheap, and you can’t have too many requirements.

When she came to the living room, Ding Yunjie sat down on her own, took out her mobile phone to play with it, and did not say any polite words to ask Chen Yi and others to sit down.

Chen Yi waited for two seconds and could only sit down by himself.

There wasn't much space to sit. Except for Xia Lan, Zhuge Cong and the others chose to stand behind Chen Yi.

Ding Yunjie was still playing with her mobile phone, as if no one was around, and the sound of short video marketing accounts echoed in the living room.

The atmosphere is a bit solid.

Chen Yi stared at her for a while, thinking about his opening remarks, and finally used the same method as when he met Ren Dan.

"He Shan was raped."

Hearing this, Ding Yunjie's sliding fingers suddenly stopped and she slowly turned her head.

Compared to the shocked Ren Dan, she was much calmer and her expression did not change much, but her eyes contained too many complex emotions.

She put down her phone.

"Why."

He wanted to say something, but in the end it all turned into a sigh.
