Detachment Commander's Office.

Listening to Geng Jianqing's words, Chen Yi touched his unshaven beard and said: "Being able to kill with one hit is either a professional advantage or an accumulation of experience, and he has not changed the murder weapon and modus operandi in the three murders, so if there is an old case, the probability is the same." ”

Geng Jianqing: "Let's find out, I'll do this, your task is the current case, if you're lucky, you may be able to save the case and directly lock the murderer." ”

Chen Yi was helpless: "Uncle Geng, you are putting pressure on me." ”

Geng Jianqing smiled and said: "You are too sensitive, I don't mean that, every time the murderer kills one more person, more clues will be exposed, as long as he is negligent in the Yangcheng case, then Yangcheng is his final judgment place." ”

"It's been a hard work these days, and in the golden time to solve the case, do your best and strive for the best result."

Chen Yi nodded: "Understood." ”

Geng Jianqing left, leaving behind the file of the Ningcheng case, and promised to send someone to send the file of the Imperial City case before twelve o'clock tonight.

Although the possibility of serial homicide cases cannot be said to be certain, the standard for combining cases has been met, and there will not be so many coincidences.

It was already 9 o'clock in the evening, Cai Wenwen's parents and younger brother had not left, and Cai's mother, who reacted most violently, tried to go to the forensic office to see her daughter again many times, but was stopped by the police.

Hours have passed, but Cai's mother's emotions have not been relieved, and they are getting more and more out of control.

Only when you are a mother can you understand her grief at the moment.

Compared with Cai's mother, Cai's father and Cai Wenwen's younger brother Cai Yupeng are relatively more receptive, although they are also heartbroken, but it is not a problem to be asked.

Chen Yi knew that he couldn't delay any longer, so he began to meet the two alone, and the other person was responsible for accompanying Cai's mother during the process to prevent the other party from acting aggressively due to emotional breakdowns.

In terms of private life, it must be the younger brother who knows more, Chen Yi first called Cai Yupeng in the inquiry room.

Cai Yupeng is twenty years old, a sophomore in college this year, and his family protects him well, but he has not completely faded away from immaturity, and the student's temperament is very strong.

He sat quietly in front of Chen Yi, his eyes were red, and the tears on his face made him look a little embarrassed.

His sister died, and it was also a bolt from the blue for his younger brother, he could no longer ask for money with his sister, and he could no longer talk to his sister about his thoughts, and in the dead of night, a huge sense of loneliness would surround him.

Some people say that the relationship between brothers and sisters can never compare to the relationship between brothers and sisters, and the difference between genders will sublimate family affection.

Chen Yi feels that this sentence is very correct.

The daughter is the father's little padded jacket, and the sister is the guardian angel of the younger brother.

Cai Yupeng, lost the angel that belonged to him.

"Yupeng." Chen Yi didn't bring a surname, and used his name to close the distance between each other, "You are a college student, I know this sentence is cruel, but it must be said that the person is dead, what you can do now is to provide more clues for the police and improve our chances of solving the case." ”

"Now, put away your grief for a moment and listen carefully to every question I ask, understand?"

Hearing the words [solve the case], anger surged on Cai Yupeng's face, replacing the original pain, and he nodded emphatically: "Okay!" ”

Chen Yi: "Does Cai Wenwen have a boyfriend?" ”

Cai Yupeng: "No, I've never heard her talk about it. ”

Chen Yi: "Did you chase her?" ”

Cai Yupeng: "Yes, my sister said that there were people chasing her in the unit, but she didn't agree, saying that she didn't like it and looked too ugly." ”

The conversation between the siblings is always more direct, and what Chen Yi gets will be the most real situation.

Chen Yi: "Did the person chasing her stalk her, did he do anything that made your sister angry?" ”

Cai Yupeng shook his head: "No, she didn't say it." ”

Chen Yi: "Does Cai Wenwen have anyone you like?" ”

Cai Yupeng: "No. ”

Chen Yi: "Where does she usually live?" ”

Cai Yupeng: "I've been living at home. ”

Chen Yi: "Does she have a house?" ”

Cai Yupeng: "No, but I do, my parents just bought me a house last year. ”

Chen Yi: "You went to university locally? ”

Cai Yupeng nodded.

Chen Yi: "Day school or residential school. ”

Cai Yupeng: "Live on campus. ”

Chen Yi: "How often do you go back?" ”

Cai Yupeng: "I usually go back on weekends, and I usually go back occasionally, not far away, and the bus arrives in more than half an hour." ”

Chen Yi: "Does Cai Wenwen have any cases where she doesn't go home at night?" ”

Cai Yupeng is sure: "Never." ”

Chen Yi: "Is there anything unusual about her lately?" Think carefully and answer carefully. ”

Cai Yupeng recalled for a long time and said: "I ...... I didn't think there was anything unusual about her, I was at school these days and I didn't contact her. ”

Chen Yi: "What hobbies does she have?" ”

Cai Yupeng: "Paint." ”

"Drawing?" Chen Yi subconsciously sat up straight, the victim of the Imperial City was a student of fine arts, "What type of painting?" ”

Cai Yupeng: "Oil painting. ”

Chen Yi: "Hobbies? ”

Cai Yupeng: "That's right. ”

Chen Yi: "When did it start?" ”

Cai Yupeng: "She likes to paint since I can remember, and she hasn't let go of it for so many years, my sister said that her dream is to be a painter, but my parents think it's not a proper job, and she was strangled to death when she was in middle school." ”

Chen Yi couldn't be sure if this was a characteristic of the crime, because Bi Xuelan from Ningcheng didn't know how to paint at all.

If the murderer's motive had something to do with painting, then why did he choose Bi Xuelan? He can completely look for a more characteristic target of the crime, there are so many girls who know how to draw, just go to school to find it.

Could it be that it's too late? Because Bi Xuelan's daughter learned to paint, she simply retreated to the next best thing and chose Bi Xuelan?

No, it's too far-fetched.

"How is Cai Wenwen's personality?" Chen Yi continued to ask.

Cai Yupeng pondered the adjective and replied: "Shy, very kind and helpful." ”

Chen Yi: "Can I understand it as an introvert? ”

Cai Yupeng nodded: "Yes, it's introverted, my sister is a very quiet person, she doesn't like to deal with outsiders very much, the reason why she took the bank exam is because of the pressure of her parents, anyway, she told me that she was not happy and always wanted to resign secretly." ”

Introverted and unsociable.

Chen Yi remembered this trait, which was consistent with Bi Xuelan, but I don't know if it was consistent with the victims of the Imperial City.

This is strange, why did an introverted and shy girl, a good girl who never goes home at night, take the initiative to open a room in Cuiping Garden on the day of the crime?

What made her open a house?

Also, whether it's secretly dating or going out with your parents or other reasons, you won't go to Cuiping Garden, right? With her work and family background, a hotel of a few hundred dollars can still be opened.

The most reasonable possibility is that the murderer asked her to open it.

Why is she so obedient?

What kind of person can make her open a house willingly?

Serial murder case, the more you kill, the more clues will be exposed, the victim of the Imperial City case died in the cemetery, the victim of the Ningcheng case died in a semi-abandoned warehouse, to put it bluntly, it can be regarded as the wild, and the victim of the Yangcheng case, Cai Wenwen, died in a daily rental house, there are many bases for analysis.

Chen Yi could feel that the distance between himself and the murderer was beginning to narrow, but it was only a stretch.

"What kind of man does your sister like?"

"Huh?"

The sudden question made Cai Yupeng stunned for a moment.

Chen Yi: "Let me ask another way, what kind of man has no resistance to Sister Ling, and vigilance will be minimized, you should understand what I mean." ”

Cai Yupeng: "That must be handsome, my sister is Yan Kong." ”

Chen Yi was not satisfied with this answer: "What about the others? For example, personality, such as career, etc., to be more specific, this matter is very important, think about it slowly, has your sister mentioned it? ”

Now he suspects that the murderer is a 120-pound bamboo pole, he doesn't think that a bamboo pole can be handsome, too fat and too thin will affect his appearance.

Cai Yupeng fell into deep thought and did not speak for a long time.

Chen Yi was not in a hurry, and waited slowly, and the victim's family was more eager to catch the murderer than the police.

In the past three minutes, Cai Yupeng raised his head: "Understanding, empathy." ”

Chen Yi: "What do you mean?" ”

Cai Yupeng explained: "My sister wants to choose her life freely, if a man's experience is the same as hers, there must be a common topic that can win her favor, you just said career...... It would be best if it was a painter, and my sister would definitely like to be friends with a painter. ”

Chen Yi asked: "Does she have such a friend?" ”

Cai Yupeng: "I haven't heard her say it. ”

Chen Yi's brows furrowed slightly.

Painting is mentioned again.

Considering the characteristics of serial killing, Bi Xuelan does not meet at all, but if the case of Cai Wenwen's murder is brought out separately, then what Cai Yupeng said is still very reasonable.

But these are just speculations, no one knows why Cai Wenwen went to open a house, and the reason for being killed is impossible to analyze.

After asking Cai Yupeng, Chen Yi met Cai Wenwen's father.

"Cai Wenwen didn't come home last night, how did she explain?" Chen Yi asked.

Cai's father seemed to be ten years old, and he said weakly: "It is said that the bank is working overtime." ”

Chen Yi: "Do you often work overtime?" ”

Cai's father: "It's a lot, I can't get off work at eleven o'clock at the latest, at that time my mother and I had already slept, she said that I didn't think much about working overtime, but I didn't expect to find that she was not at home at all the next morning, and the phone couldn't get through......"

At the end, he choked up and held back tears.

Chen Yi: "Mr. Cai, what does Cai Wenwen do on weekends and holidays?" ”

Cai's father quietly wiped away a handful of tears and replied: "Sometimes I paint at home, sometimes I go out to party with friends, I don't know what to do, I rarely ask about their private affairs when the children are older, and I don't say anything when I ask them." ”

After chatting with Cai's father for a while, Chen Yi proposed to go to Cai Wenwen's bedroom to have a look, Cai's father agreed, it was good to have the police follow him home, and he was really worried that his wife would jump into the river on the way back.
