Chapter 442: Follow the Directions of Acquaintances First

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 goal of committing the crime 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 have played it before. Script killing is very suitable for playing with strangers. It is quite interesting and the sense of solving puzzles is stronger."

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 ropes used to tie the victims were not climbing nylon ropes, but ordinary thin hemp ropes. 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 ruled out, and the suspects that Ren Dan thought of were outrageous, and they could not advance the case, let alone close it.

Several people were wondering if the four of them were targeted by a pervert when they were out partying.

"Could it be a stranger?" Lu Minghe said.

Chen Yi did not answer, and Zhuge Cong spoke up: "If it was a stranger, why did they disfigure He Shan? Why did they 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, and it is possible that she angered the suspect."

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

He Shan was so venomous to her friends, let alone the suspect. Who knows what she said to cause the suspect to lose his mind in anger and become extremely violent.

With tooth marks and disfigurement, one can imagine the suspect's terrible state at the time.

Lu Minghe turned his head: "What do you think, Captain Chen?"

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

"If he had a sharp weapon with him when committing the crime, the inference would be reasonable. If he only had a sharp weapon when committing the crime against He Shan, the inference would not be reasonable."

"We have no way of knowing whether he had it with him or not."

"But what Captain Lu said is logical. We can assume that the suspect had a sharp weapon with him all the time, but he did not use it when committing 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 security, so I think he should have carried it with him all the time."

Chen Yi: "If that's the case...it's hard to investigate. The suspect has no criminal record, and there are so many people."

Lu Minghe was silent. It can be heard that Chen Yi temporarily disagrees with the stranger committing the crime. From the data, the possibility of a person with no criminal record suddenly planning to commit a big crime against a stranger is very small.

It is quite rare for a case to happen. The suspects in such cases basically have big 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 the acquaintance, go find Ding Yunjie, and call to make an appointment. Captain Lu, you personally take the trace inspection to Ren Dan's house and check it carefully. Try to be comprehensive and don't just focus on the room where the crime occurred."

When Ren Dan woke up, the suspect was already lying on him. Before that, it was impossible to know whether the suspect had other behaviors or whether he was moving around the whole house, so he couldn't be missed.

Lu Minghe: "Okay."

...

Ding Yunjie rents a house and is now an online novel writer. She stays in the rented house all day to write and rarely goes out.

This is what she said on the phone.

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

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

It seems that she rarely goes out, and even orders takeout for meals.

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

Knock, knock, knock!

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

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

Her skin had lost its luster, and was pale, sallow and dull, as if shrouded in a layer of gray fog.

She had serious dark circles under her eyes, as if caused by staying up late, and her eyes looked dull and empty, and her drooping eyes revealed an unspeakable sense of fatigue.

Not to mention her hair, which was messy and disorderly, and had not been taken care of for several days.

Two words to describe Ding Yunjie: decadent.

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

I don't know if the other party has become like this because of the influence of rape.

"Hello, my last name is Chen." Chen Yi smiled kindly.

Ding Yunjie had a blank expression on her face and turned to make way: "Come in."

Everyone walked in. The whole room was simply decorated. The furniture they saw was a bit old, and some of the wall paint was peeling off due to mold, which affected their mood.

The living environment was average.

The rent of the resettlement house was cheap, and they could not have too many requirements.

When they came to the living room, Ding Yunjie sat down by herself, took out her mobile phone to play, and did not say any polite words to let Chen Yi and the others sit down.

Chen Yi waited for two seconds and had to sit down by himself.

There was not much space to sit. In addition to 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. The sound of short video marketing accounts echoed in the living room.

The atmosphere was a bit frozen.

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

"He Shan was raped."

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

Compared to the shocked Ren Dan, she was much calmer, her expression didn't change much, but her eyes contained too many complicated emotions.

She put down her phone.

"Hey."

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