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

As soon as he arrived, Chen Yi immediately called Shi Xin over and chatted with the other party about his experience last night.

"Bi Xuelan?" The familiar name made Shi Xin pull his memory back to two years ago, nodded and said: "That's right, there was indeed a murder in Ningcheng two years ago, the deceased was a woman, twenty-nine years old, who was pierced in the throat by a sharp weapon in the bound state, injured an artery, and died of excessive blood loss. ”

Chen Yi: "Tell me specifically. ”

Shi Xin was very impressed by this case, after all, it was a homicide, and seeing that Chen Yi wanted to know the whole picture of the case, he said without thinking: "The place of death is in the partition room of a warehouse in Ningcheng, there are no windows, it is completely sealed, only a small door to enter and exit, and when we arrived at the scene, the door was open." ”

"Bi Xuelan's interpersonal relationship is very simple, the full-time mother has no job, and her daily life is to take care of her children and her husband's daily life, whether it is the results of the visit or the results of the mobile phone inventory, no suspicious person has been found."

"On the day of the crime, Bi Xuelan went out to buy vegetables to cook dinner for her husband and children, and disappeared mysteriously on the way back, and when she was found again, the person was already dead, and the vegetables and meat she bought were scattered at the scene of the disappearance, and there was no surveillance around."

Chen Yi: "Disappeared in broad daylight?" ”

When is new: "Yes, there are no witnesses who disappeared during the day, and that road is rarely walked, it is a short way back to the community, and the residents of the community usually walk, and the time of disappearance is work time, and there are fewer people." ”

"At that time, we analyzed that it was not the murderer's luck, we must have stepped on it in advance, knew Bi Xuelan's habitual route, and knew where it was safest to do it."

"Oh yes, no property lost, no traces of sexual assault, no other trauma, I still can't figure out the motive of the murderer, the area of the visit has finally been expanded to elementary school classmates, and still no suspect has been found."

"Don't talk about suspicion, there are no contradictions, everyone said that Bi Xuelan is very introverted, and there is a little social fear, even if she suffers a loss when she encounters trouble, she doesn't want to argue with the other party, and it is impossible to offend people."

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

When is new: "About ten kilometers." ”

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

As long as the vehicles that have appeared at the same time, they are the key objects of investigation.

When Xin nodded: "Checked, the road at the scene of the disappearance is being planned and renovated, there is little monitoring, and there are at least three paths that can avoid monitoring, the warehouse where the death scene is located has been semi-abandoned, the location is very biased, and the internal monitoring of the warehouse has long been deactivated." ”

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

When is new: "The rut mark near the scene of the death is an SUV. ”

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

"The victim had inhaled sevoflurane, but was conscious at the time of the killing."

Chen Yi: "So thin? ”

One meter eight two hundred and twenty pounds, it is a bamboo pole, an obvious feature.

Shi Xin said: "Judging from the footprints, this person is most likely a 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?" ”

When is new: "No, it's just an ordinary family, life is normal." ”

Chen Yi: "What about Bi Xuelan's activities before the case?" ”

When is new: "I have checked everything, I haven't been to a suspicious place, I haven't known any suspicious people, she stays at home when her husband goes to work and the children go to school, and she goes out to buy daily necessities." ”

"I've been to the store, I've checked, I've been to the barbershop, I've checked, and the courier station that frequents me has also checked."

"In the past year, she has accompanied her daughter to the playground, to the exhibition hall, to learn painting, to learn guitar, and to go to the movies and eat food with her husband alone......

"We have mastered all her movements, all the people she knows, as long as we can check the place, nothing is missing."

"It's the Internet age, if there is a deep hatred that you have to kill, I don't think you can't find any traces, right?"

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

Even if the case is a little more complicated, there is always a source to be traced and hope can be seen, but this case has no other gains except for finding the footprints of the suspected suspect and the ruts left by the car, and it is indeed very much like a stranger who randomly chooses 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 trait in Bi Xuelan that attracts suspects.

"Is it really a random crime?"

Chen Yi believes in Xie Yunzhi's ability, judging from the new description, the investigation of this case has indeed covered a very wide range, even if he is responsible, it may be the same result, the only variable is whether there are important details that have been overlooked in the process of visiting.

In particular, the inquiry about Bi Xuelan's husband.

Different criminal police officers will definitely have different gains when facing the same interview object, and it is impossible to ask everything clearly.

What you think is suspicious, others may not think so.

This is a difference in the habit of investigating cases, and it has nothing to do with ability.

Also, if his wife dies, he suspects her husband first, and Xie Yunzhi must be the first to investigate Bi Xuelan's husband, and the suspicion should have been ruled out.

"Has Bi Xuelan's daughter's interpersonal relationship been checked?" Chen Yi asked.

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

When is it new: "Checked, it's still ...... Everything works fine. ”

Knowing this, Chen Yi picked up the cigarette case, took out a 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 ability, but the fact that there is no connection and any directional traces, which cannot be checked.

Shi Xin agreed: "That's right, if you stab someone on the road without monitoring in the middle of the night and run, it will be difficult to find." ”

Chen Yi: "Sevoflurane ......"

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

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

Seeing Fang Songping's name, he hurriedly connected.

"Hello? Square Hall. ”

Fang Songping: "Chen Yi, Director Geng asked you to talk to him for the past two days, why haven't you seen anyone?" ”

Chen Yi didn't expect Fang Songping to ask about this, his head flashed, and he pushed it to Fang Shuyu and Shi Xin: "We went to Ningcheng to climb the mountain, when Xin went back to his hometown the day before yesterday and pulled me, Shuyu knew that Hou Fei followed, and I couldn't help it, in fact, I really wanted to communicate and learn with Teacher Geng, but I really couldn't resist Shuyu." ”

When is it new: "......"

He should be scolding in his heart.

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 fooled him to Ningcheng.

Anyway, it has nothing to do with me.

Fang Songping: "That's okay, he's going to leave Yangcheng and return to the Imperial City this morning, why don't you come to send it off?" ”

Chen Yi: "Go, why don't you go, you have to go, I'll go." ”

Fang Songping: "Hmm. ”

The phone hangs up.

Chen Yi knew that Fang Songping should want him to be close to Geng Jianqing, after all, he was a member of the Imperial City Police Department, and he had a direct relationship with his career and had good intentions.

"I'll go to the provincial hall, you can be busy." Chen Yi stood up.

When new: "Okay. ”

……

Provincial Offices, Offices.

Chen Yi, who came quickly, knocked on the door, and after getting permission, pushed the door and walked in.

Fang Songping and Geng Jianqing were sitting on the sofa chatting, their briefcases were ready, and it seemed that they were going to go directly to the airport or high-speed rail station from the provincial hall.

Chen Yi understands that he is going to be a driver today.

"Chen Yi, come and sit, Lao Geng has been talking about you for a long time." Fang Songping beckoned to Chen Yi, at this moment, the other party was not a subordinate, but a future son-in-law.

"Uncle Fang, Teacher Geng."

Chen Yi stepped forward and sat down and said hello.

Geng Jianqing said with a smile: "Call my uncle, you don't suffer, it's really not easy to see Captain Chen, you went directly to Ningcheng during the two-day holiday, are you hiding from me?" ”

Chen Yi hurriedly denied: "Of course not, Uncle Geng misunderstood, I really want to meet you, there is no way, my fiancée has to go to climb the mountain, I can't stop it." ”

It is absolutely impossible to push Fang Shuyu out, his wife is used to pit.

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

Chen Yi: "That's right. ”

Geng Jianqing was a little nostalgic: "I went there once more than ten years ago, and the scenery is really good, right, Lao Fang?" ”

Fang Songping nodded with a smile: "Yes, I was also there at the time, but I didn't expect so many years to pass." ”

Geng Jianqing: "While the body is not old enough to decay, I have to find time to go again, what do you say?" ”

Fang Songping: "Okay, I also want to go once, so it's decided, find a time then." ”

Chen Yi looked at the two of them, and chose to be a little transparent, what you talk about has nothing to do with me, and when you finish talking, I will end the task after sending people away.

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

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

There has been no breakthrough in the past two years, there must be something missing, he naturally won't say this sentence to when he hears it, let alone Xie Yunzhi, just think about it in his heart.

So, where is the omission?

Without a complete dossier, it is difficult to judge just when the description was new, and it is more likely that Chen Yi considered Bi Xuelan's experience.

Experience is precisely the most difficult to check.

The interpersonal relationship is easy to check, and the eight generations of ancestors can find it out for you, but the experience is private, and the police cannot achieve 100% comprehensive coverage during the investigation.

"Chen Yi, what do you want?" Geng Jianqing suddenly spoke.

"Huh?" Chen Yi came back to his senses, "I didn't think about anything, listen to you." ”

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

Fang Songping glared: "Chen Yi! ”

Chen Yi sneered: "I'm sorry, I want to think about the case, I went to Ningcheng this time and heard about a murder case, and I haven't caught the murderer for two years." ”

Geng Jianqing was interested: "Oh? What kind of case? ”

Chen Yi didn't hide it, and probably said it.

It was originally a small talk, but I didn't expect Geng Jianqing's smile to retract after listening, and his face became serious.

Chen Yi saw that something was wrong and began to be serious: "Uncle Geng, what's wrong?" Is there something wrong? ”

Geng Jianqing was silent for a moment and said: "Four years ago, there was a murder in the Imperial City, the victim was a student of the Imperial City Normal University, a local, and the cause of death was excessive blood loss due to a sharp weapon in the throat. ”

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 has not gained anything from a month's investigation, and later I participated in the guidance and investigation of this case, digging deep into the victim's interpersonal relationships and all the activities in the Imperial City, but still did not find any clues." ”

Chen Yi: "Strangers committing crimes? ”

Geng Jianqing: "I didn't come to this conclusion lightly at that 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 loss and personal injury? ”

Geng Jianqing: "No loss of property, no traces of sexual assault, no other external injuries except for fatal injuries." ”

Chen Yi: "Characteristics of the suspect? ”

Geng Jianqing: "No. ”

Chen Yi's brows furrowed, very similar.

The merger of serial homicide cases requires clear evidence, which must be done with caution, otherwise there will be a serious deviation in direction.

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

There is no need to worry too much between masters, just get straight to the point, Geng Jianqing has evaluated the other party as a rare genius in solving cases since he read Chen Yi's information resume.

Chen Yi thought for a while, and then replied: "The time interval and modus operandi are basically the same, but the geographical span is so large, it's a bit weird, kill someone to change places?" If you don't want money, you don't want to make money, what do you want? ”

Now is the guesswork stage, and you can be bold and come up with any possibility.

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

Chen Yi nodded: "Yes." ”

This is indeed one of the common denominators.

Fang Songping didn't expect that today's farewell suddenly turned into a case discussion, and as a police officer, he also joined in: "There was no breakthrough in the investigation of interpersonal relationships in the two cases, and it is necessary to suspect the possibility of strangers committing crimes, which is another common denominator." ”

Female, no loss of finances, no traces of sexual assault, no external injuries, the same cause of death, the same time interval, the same anti-reconnaissance ability, strangers committed the crime......

If there are many coincidences, it is inevitable, and it is already possible to lean in the direction of serial murders.

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

Of course, the police do not want to continue to die, but the possibility is real, big or small.

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

Before Geng Jianqing could answer, Chen Yi's mobile phone rang, he took out his mobile phone and glanced at it, it was Zhuo Yun calling.

"I'm sorry."

The phone is connected.

"Hello? What's up? ”

Zhuo Yun: "Team Chen, there was a murder in Cuiping Garden, the police station in the jurisdiction has taken control of the scene, the deceased is a young woman, and I heard the police over there say that her throat seems to have been pierced." ”

Chen Yi: "Let Lao He bring someone over first, and I'll arrive later." ”

Zhuo Yun: "Yes. ”

The phone hung up, Chen Yi turned his head to look at Fang Songping and Geng Jianqing: "Very bad news, murder, female, throat pierced." ”

Fang Songping's face sank.

Geng Jianqing, who has always remained indifferent, has become extremely exciting at this moment, and his eyes are sharp.

Chen Yigang wanted to continue to speak, but was interrupted by Geng Jianqing: "Don't guess first, you go to the police first." ”

"Okay, then I'll go." Chen Yi got up and walked out of the office quickly.

In the room, Geng Jianqing changed his mind: "Old Fang, don't go back to the Imperial City first, let Ningcheng pass over a copy of the relevant files of the case." ”

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