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

The next morning, Yangcheng City Bureau, Criminal Investigation Detachment Captain's Office.

As soon as he arrived, Chen Yi immediately called He Xin over and chatted with him about his experience last night.

"Bi Xuelan?" The familiar name brought Shi Xin's memory back to two years ago, and he nodded: "Yes, there was indeed a murder case in Ningcheng two years ago. The deceased was a woman, 29 years old, in While tied up, his throat was pierced with a sharp instrument, which damaged his artery, and he bled to death."

Chen Yi: "Tell me specifically."

He Xin was deeply impressed by the case. After all, it was a murder case. Seeing that Chen Yi wanted to know the whole case, he said without hesitation: "The place of death was in a partition room of a warehouse in Ningcheng. It has no windows and is completely sealed. There is only one way in and out." The small door, when we arrived at the scene, the door was open.”

"Bi Xuelan's interpersonal relationship is very simple. The stay-at-home mother has no job, and her daily life is to take care of her children and her husband. No matter the results of the visit or the results of the cell phone inventory, no suspicious person was found."

"On the day of the incident, Bi Xuelan went out to buy vegetables to prepare dinner for her husband and children. She disappeared mysteriously on the way back. When she was found again, she was already dead. The vegetables and meat she purchased were scattered at the scene of the disappearance, and there was no surveillance around."

Chen Yi: "Disappeared in broad daylight?"

Shi Xin: "Yes, there are no witnesses to the disappearance during the day. That road is rarely used by people. It is a shortcut back to the community. Usually only residents of the community use it. The time of disappearance is during working hours, so there are even fewer people. ”

"At that time, we analyzed that this was not because the murderer was lucky. He must have been there in advance and knew Bi Xuelan's usual route and knew where was the safest place to take action."

"Oh, by the way, there is no property missing, no signs of sexual assault, and no other trauma. I still can't figure out the murderer's motive. The area visited has finally been expanded to include elementary school students, but no suspects have been found."

"Don't talk about suspicions. There are no conflicts. Everyone said that Bi Xuelan is very introverted and a little bit social. When she encounters trouble, she is unwilling to argue with the other party even if she suffers a loss. It is impossible to offend others."

Chen Yi thought while listening, and said: "It's really strange. She doesn't seek wealth, sex, and has no enemies, but the murderer chose her... How far is it from the disappearance scene to the death scene?"

When was it new: "About ten kilometers."

Chen Yi: "Have you checked the vehicles near the two scenes?"

As long as vehicles appear at the same time, they will be the focus of investigation.

Shi Xin nodded: "We checked, the road at the disappearance site is being renovated. There are few surveillances, and there are at least three small roads that can avoid surveillance. The warehouse where the death scene is located is semi-abandoned, and the location is very remote. All internal surveillance of the warehouse has been completed. Deactivate."

Chen Yi: "How many clues did you have at that time?"

WHEN NEW: "The rutted tracks near the death scene were an SUV."

"The footprints near the rut marks are initially judged to be male, about 1.82 meters tall and weighing about 120 kilograms."

"The victim had inhaled sevoflurane but was conscious when he was killed."

Chen Yi: "So thin?"

At 1.82120 pounds, it is just a bamboo pole, with obvious characteristics.

Shi Xin said: "Based on the footprints, this person is most likely the suspect."

Chen Yi was silent for a while and said: "The investigation is extensive, which means that Bi Xuelan has no enemies and her family has no enemies either?"

Shi Xin: "No, it's just an ordinary family, life is normal."

Chen Yi: "What was Bi Xuelan's activity before the incident?"

Shi Xin: "Everything has been checked. She has not been to any suspicious places or met any suspicious people. She stays at home when her husband goes to work and the children go to school. She only goes out to buy daily necessities."

"The stores I visited were checked, the barber shops I visited were checked, and the courier stations I frequented were also checked."

"In the past year, she has accompanied her daughter to amusement parks and exhibition halls, learned painting and guitar, and also went to the movies alone with her husband, and ate delicious food..."

"We have all the traces of her activities and all the people she knows. As long as we can check, there is no omission."

"This is the Internet age. If there is a deep hatred that requires killing people, I don't think there should be any traces of it, right?"

Chen Yi understood. The final judgment given by the Ningcheng Criminal Investigation Detachment was that a stranger committed the crime.

Even if the case is more complicated, there is always a source that can be traced and hope can be seen. However, apart from finding the footprints of the suspected suspect and the ruts left by the car, there is no other harvest. It is really like a stranger randomly choosing the target of the crime.

Chen Yi knew in his heart that as long as he was mentally normal and there was no pure randomness, there must be a reason why the suspect chose Bi Xuelan as the target of the crime.

For example, Bi Xuelan's experience.

For example, there is a certain quality in Bi Xuelan that attracts the suspect.

"Is it really a random crime?"

Chen Yi believes in Xie Yunzhi's ability. Judging from the new description, the investigation of the case has indeed covered a very wide range. Even if he is responsible, the result may be the same. The only variable is whether there is any neglect during the visit. Important details left out.

In particular, the inquiry was directed at Bi Xuelan's husband.

When different criminal police officers face the same interview target, their results will definitely be different. It is impossible to ask everything clearly.

What you think is doubtful may not be what others think.

This is a difference in investigation habits and has nothing to do with ability.

Also, after the wife died, the husband was suspected first. Xie Yunzhi must have been the first to investigate Bi Xuelan's husband, and the suspicion should have been eliminated.

"Have you checked Bi Xuelan's daughter's interpersonal relationship?" Chen Yi asked.

Bi Xuelan's daughter Zhou Yumeng is in elementary school, and interpersonal relationships have begun to be established, which cannot be ignored.

When was it new: "I checked, and it's still...everything is normal."

After learning this, Chen Yi picked up the cigarette box, took out the cigarette and lit it, and said: "The simpler the case, the more bizarre it is."

The really complicated case is not the murderer's high IQ and anti-reconnaissance capabilities, but the fact that there is no connection or any pointing traces, and it is impossible to find out.

Shi Xin agreed: "Yes, if you stab someone on an unmonitored road in the middle of the night and run away, it will be difficult to find him."

Chen Yi: "Sevoflurane..."

He originally wanted to ask about the investigation of sevoflurane, which is a national controlled drug and is not easy to obtain.

At this time, the phone rang, and it was Fang Songping.

Seeing Fang Songping's name, he quickly answered the call.

"Hello? Fang Ting."

Fang Songping: "Chen Yi, Director Geng asked you to chat with him if you have nothing to do these two days. Why haven't you seen anyone?"

Chen Yi didn't expect that Fang Songping would ask about this matter. An idea flashed in his mind and he pushed it to Fang Shuyu and He Xin: "We went to Ningcheng to climb mountains. When He Xin returned to his hometown the day before yesterday, Fei took me with him. Shuyu knew that Fei was There's nothing I can do if I go with you. In fact, I really want to communicate and learn with Teacher Geng, but I really can't resist Shu Yu."

When was it new: "..."

He should be cursing in his mind.

Chen Yi ignored Shi Xin's gaze. He didn't lie. When the other party invited him the day before yesterday, he refused, and it was indeed Fang Shuyu who tricked him into Ningcheng.

It has nothing to do with me anyway.

Fang Songping: "That's okay. He is leaving Yangcheng and returning to Imperial City this morning. Why don't you come to see him off?"

Chen Yi: "Go, why don't you go? You must go, I'll go now."

Fang Songping: "Yeah."

The phone hangs up.

Chen Yi knew that Fang Songping probably wanted him to get close to Geng Jianqing. After all, he was from the Imperial City Police Department, had a direct relationship with the official career, and had good intentions.

"I'll go to the provincial office. You can do your work." Chen Yi stood up.

When is new: "Okay."

…

Provincial Department, Office.

Chen Yi rushed over and knocked on the door. After receiving permission, he opened the door and walked in.

Fang Songping and Geng Jianqing were sitting on the sofa chatting. Their briefcases were ready. It seemed they were going directly from the provincial government office to the airport or high-speed rail station.

Chen Yi understood that he had to be a driver today.

"Chen Yi, come and sit down, Lao Geng has been talking about you for a long time." Fang Songping waved to Chen Yi. At this moment, the man was not a subordinate, but his future son-in-law.

"Uncle Fang, Teacher Geng."

Chen Yi came up and sat down and said hello.

Geng Jianqing smiled and said: "You won't suffer any loss by calling me uncle. It's not easy to meet Captain Chen. I went directly to Ningcheng during the two-day holiday. Are you avoiding me?"

Chen Yi quickly denied: "Of course not. Uncle Geng misunderstood. I really want to meet you. I have no choice. My fiancée has to go hiking. I can't stop her."

There is absolutely nothing wrong with pushing Fang Shuyu out. His wife is here to deceive him.

Geng Jianqing didn't say much, and he didn't know whether he believed it or not. He asked, "Fushan?"

Chen Yi: "Yes."

Geng Jianqing felt nostalgic: "I went there once more than ten years ago. The scenery is really good, right Lao Fang?"

Fang Songping nodded with a smile: "Yes, I was there at that time. I didn't expect that so many years have passed so quickly."

Geng Jianqing: "I have to find time to go there again before my body gets old and decays. What do you think, Lao Fang?"

Fang Songping: "Okay, I was thinking of going there once too. That's it. I'll find a time then."

Chen Yi looked at the two of them and chose to be a little transparent. What you guys are talking about has nothing to do with me. When you finish talking, I will send you off and the mission will be over.

He sat there with a humble face, listening carefully to the conversation and laughter between the two, his thoughts drifting away again.

There is no perfect crime, only imperfect investigation. These are Geng Jianqing's original words, which can be used in this murder case in Ningcheng.

There had been no breakthrough progress in two years, so there must be something missing somewhere. Naturally, he would not say this to He Xin, let alone Xie Yunzhi. He could just think about it in his own mind.

So where would the omission be?

Without a complete file, it is difficult to judge based on when the new description was released. Chen Yi considered Bi Xuelan's experience more likely.

Experience is precisely the most difficult thing to check.

Interpersonal relationships are easy to investigate, and eight generations of ancestors can dig them out for you, but experiences tend to be private, and the police cannot achieve 100% comprehensive coverage during the investigation process.

"Chen Yi, what are you thinking about?" Geng Jianqing suddenly said.

"Ah?" Chen Yi came back to his senses, "I didn't think about anything. I was listening to you."

Geng Jianqing looked at Fang Songping: "Old Fang, your son-in-law is a bit slippery."

Fang Songping glared: "Chen Yi!"

Chen Yi said: "Sorry, I am thinking about a case. I went to Ningcheng this time and heard about a murder case. It has been two years and the murderer has not been caught yet."

Geng Jianqing became interested: "Oh? What kind of case?"

Chen Yi didn't hide anything, he probably said it.

It was originally a casual chat, but Geng Jianqing's smile suddenly faded and his face became serious after listening.

Chen Yi saw something was wrong and began to ask seriously: "Uncle Geng, what's wrong? Is there something wrong?"

Geng Jianqing was silent for a moment and said: "Four years ago, a murder occurred in Imperial City. The victim was a student at Imperial City Normal University and a local. The cause of death was that his throat was penetrated by a sharp instrument and he died of excessive bleeding."

Hearing this, Chen Yi became completely serious and asked: "The case has not been solved?"

Geng Jianqing shook his head: "No, the Imperial City Bureau's one-month investigation yielded nothing. Later, I participated in guiding the investigation of the case. I dug deep into the victim's interpersonal relationships and all activities in the Imperial City, but I still found nothing." clue."

Chen Yi: "A stranger committed the crime?"

Geng Jianqing: "I did not come to this conclusion easily at the time."

Chen Yi: "Where is the crime scene?"

Geng Jianqing: "Cemetery."

Chen Yi: "Are you tied up?"

Geng Jianqing: "No."

Chen Yi: “What about financial losses and personal injuries?”

Geng Jianqing: "No property was lost, no signs of sexual assault, and no other injuries except fatal injuries."

Chen Yi: "Characteristics of the suspect?"

Geng Jianqing: "No."

Chen Yi frowned, very similar.

Consolidation of serial murder cases requires clear evidence, and one must be cautious about this, otherwise the direction will be seriously deviated.

Geng Jianqing looked at Chen Yi: "Do you think it was done by one person?"

Experts don't have to worry too much, just get straight to the point. After reading Chen Yi's resume, Geng Jianqing has already evaluated Chen Yi as a rare crime-solving genius.

Chen Yi thought for a while and answered the question incorrectly: "The time interval and the modus operandi are basically the same, but the geographical span is so large. It's a bit weird. Killing a person and changing places? Not for wealth or sex, what are you after?"

Now is the guessing stage, and you can boldly propose any possibility.

Geng Jianqing: "It's a pity that there are no suspect characteristics in the Imperial City case. Don't forget one thing in common: the murderers all have strong anti-reconnaissance capabilities."

Chen Yi nodded: "Yes."

This is indeed one of the common denominators.

Fang Songping did not expect that today's farewell would suddenly turn into a case discussion. As a police officer, he also joined in: "Both cases have not made any breakthroughs in the investigation of interpersonal relationships. It is necessary to suspect the possibility of strangers committing the crime. This is another case." It’s a common denominator.”

Female, no financial loss, no signs of sexual assault, no trauma, consistent cause of death, consistent time interval, consistent anti-reconnaissance capabilities, stranger committing the crime...

If there are too many coincidences, it is inevitable, and it can completely lead to a serial murder case.

Geng Jianqing: "If it is really a serial murder case, and it has been two years now, will the suspect continue?"

Of course the police don't want to continue killing people, but the possibility, no matter how big or small, is real.

Fang Songping: "Check similar cases across the country?"

Before Geng Jianqing could answer, Chen Yi's cell phone rang. He took it out and took a look. It was Zhuo Yun calling.

"Excuse me."

The call is connected.

"Hello? What's going on?"

Zhuo Yun: "Team Chen, a murder occurred in Cuiping Garden. The local police station has taken control of the scene. The deceased is a young woman. The police over there said that her throat seemed to have been stabbed."

Chen Yi: "Let Lao He take the people there first, I will be there soon."

Zhuo Yun: "Yes."

After hanging up the phone, Chen Yi turned to look at Fang Songping and Geng Jianqing: "Very bad news, murder case, female, throat pierced."

Fang Songping's face darkened.

Geng Jianqing, who had always remained calm, his expression became extremely exciting at this moment, and his eyes suddenly became sharp.

Chen Yigang wanted to continue speaking, but was interrupted by Geng Jianqing: "Don't make blind guesses yet, call the police first."

"Okay, then I'm leaving." Chen Yi stood up and left the office quickly.

In the room, Geng Jianqing changed his mind: "Old Fang, don't go back to the Imperial City now. Let Ningcheng send over a copy of the relevant files on the case."

Fang Songping: "Okay, I'll make a call."
