The community where the Cai family is located is located in the center of the city, and three generations are locals, born and raised, and the whole family has a system except for college students, and it is a very stable family.

Although you can't be rich and expensive in this life, you can ensure that you don't have to worry about food and clothing, and you can ensure income from drought and flood.

Cai Wenwen's death will break the existing happiness of the Cai family, this thorn can never be pulled out, even if the police catch the murderer and sentence him to death in the future, it is only to comfort them, and it cannot make up for the pain in their hearts.

Along the way, the atmosphere dropped to the freezing point, and Chen Yi didn't say anything comforting, and the four words of mourning and change were mostly polite, which would not have any effect on the victims' families.

They need to be quiet, they need psychological defense mechanisms to accept slowly.

Life goes on after all.

When he came to Cai's house, Cai's father pushed open the door of one of the bedrooms, and the familiar room and smell made Cai's father burst into tears instantly, and he hid his face and left quickly.

Cai's mother was already lying on the bed, her eyes were blank, and Cai Yupeng was taking care of her.

No one cares about the police of the criminal investigation detachment anymore.

Chen Yi beckoned, and the technical detective put on gloves and shoes and entered Cai Wenwen's room, carefully searching and investigating.

This is a boudoir for single girls, like a small world isolated from the world, and the air exudes a unique perfume smell, which is refreshing.

Chen Yi walked at the back, slowly put on his gloves, and turned his head to look at several oil paintings on the wall.

The oil paintings are rich in color and smooth lines, some depict country houses, some show the vast grassland, and each painting is a story that makes people immersed in it.

I took a closer look, and the name was Wen in the lower right corner.

This was painted by Cai Wenwen.

Chen Yi doesn't know oil painting, but he still has appreciation, Cai Wenwen's painting level is obviously not low, but I don't know whether it has reached the amateur level or the professional level.

In one corner of the room, a vintage-style wooden easel covered with a clean white canvas awaits the painter's next creation.

Unfortunately, its owner won't have the next pen.

Next to the easel is a large desk, on which are arranged and arranged with paintbrushes, paints and various painting tools, everything is well organized, which not only shows Cai Wenwen's love and dedication to painting, but also reflects Cai Wenwen's rigorous and meticulous character.

Chen Yi stepped forward and picked up an oil painting spatula, as Geng Jianqing said, the oil painting spatula is very similar to the murder weapon in this case, the difference is that the oil painting spatula is sharp and round, and no matter how much force you use, it is impossible to cause a stab wound, let alone kill a person.

He broke it gently, the scraper was easily twisted, and it had a certain softness.

There is softness, and it is even less likely to be a tool for killing.

The murder weapon will definitely not be an oil painting spatula, unless the murderer has made a custom custom, using a high-hardness material and cutting the scraper, while sharpening the sleek tip.

Putting down the oil painting spatula, Chen Yi looked at the whole room, the color tone was mainly light colors, and the soft light covered every corner, warm and quiet.

Coming to the window, he looked down at the greenery in front of him, which was full of greenery and added vitality to the room.

This is a girl who loves life.

Chen Yi, who is calm on the surface, has anger in his heart at this moment, a college student in the prime of the imperial city, a hard-working full-time mother in Ningcheng, and a single girl in Yangcheng who loves life.

He couldn't figure out why the three of them died tragically one after another, and it was because he couldn't figure it out that the anger against the murderer came to his face and gradually overwhelmed him.

No matter how long it takes, this case must be solved, and he really wants to see what kind of dog thing the person hiding behind is.

"Team Chen."

The officer handed over a small note.

Chen Yi took it and took a look, this is Cai Wenwen's itinerary record, she has the habit of memorizing notes.

Oil Painting Art Gallery.

Company team building.

Water Jade Gallery.

Picnic dinners.

Public Welfare Art Exhibition.

Qiu Wenshu's oil painting studio.

……

Chen Yi probably flipped through it, most of it was related to oil paintings, and his eyes were finally fixed on the name Qiu Wenshu, and the relationship between people with a common language should be very good.

"Most of Cai Wenwen's world is oil paintings, if for some reason it leads to death, then ......"

Chen Yi had already begun to sketch the portrait of the suspect in his mind, and at this moment he labeled it as a "painting".

With the same hobbies and a common language, vigilance will definitely be reduced, coupled with a three-inch tongue, it is not impossible to fool Cai Wenwen to take the initiative to open a house.

Moreover, opening a house does not have to be for the sake of men and women.

"They all took the initiative to open the house, Cai Wenwen, as an adult, will inevitably think in that direction, basically acquiescing, but the murderer has no interest in a good-looking single girl, if it weren't for the Ningcheng case to get the footprints of the suspected murderer, it really doesn't have to be a man."

"Hmm...... It's supposed to be a man, and it's strange for two girls to open a room. ”

"Why? What did he want? ”

"Release your emotions? Emotions transform violence? Psychological satisfaction? ”

Now is not the time to analyze the murderer's scheme, and more clues need to be obtained.

The investigation of Cai Wenwen's room lasted more than an hour, and there were no items belonging to the man, and no gifts from the opposite sex were found.

Before leaving, Chen Yi stood in front of Cai Wenwen's bookcase for a long time, focusing on magazines about oil paintings, including "Chinese Oil Painting", "Art World" and so on.

The traces of "Art World" are very obvious, and Cai Wenwen should read it often.

Chen Yi picked up "Art World".

Founded in 1979, this is a journal sponsored by Shanghai Literature and Art Publishing Group, which is rich in content and not limited to oil paintings.

There were about a dozen books in the bookcase.

Chen Yi noticed that the date of "Art World" was last year, so he continued to rummage, found the year before last, and found the year before last...... Except for this year's.

"Huh? Didn't buy it? ”

Chen Yi did not let go of any suspicions, took out his mobile phone to search, and found that "Art World" had been suspended for a year, and no new journal had been issued within a year.

"Take these books back with you."

"Yes, Team Chen."

After obtaining the consent of Cai Wenwen's father, the police officers left Cai's house with a large stack of books, and there was still a harvest, at least they learned about Cai Wenwen's main itinerary in the recent period.

Cai Wenwen took the initiative to open the room for the first time and did not return at night, so the murderer definitely met Cai Wenwen on a certain occasion and won Cai Wenwen's favor.

The two knew each other.

Back at the city bureau, the results of the surveillance investigation came out, and in the elevator monitoring of Cuiping Garden, nothing was found.

The murderer did not take the elevator to the scene of the crime.

On the twelfth floor, it didn't take much effort to climb up, and Lu Yongqiang, under the new instructions, had already gone to Cuiping Garden for the second time, trying to find the footprints left by the stairs.

No suspicious figures have been found in the surrounding surveillance for the time being, the investigation is still ongoing, and the identity of the strange man needs to be confirmed, and the scope is gradually expanding.

In the early hours of the morning, Fang Shuyu came to the detachment leader's office and put the autopsy report in front of Chen Yi.

"There were no signs of sexual assault, no other wounds except for a stab wound to the neck."

"From the stomach of the deceased, triazolam was detected."

Fang Shuyu briefly summarized and picked the key points.

"Triazolam?" Chen Yi opened the autopsy report.

Triazolam is a tranquilizer, mainly used to treat insomnia, with sedative and hypnotic effects.

"Shuyu, hurry up and go back to rest, and talk about it tomorrow."

Fang Shuyu poured Chen Yi a glass of water and put it in front of him, and said with concern: "You want to stay up all night again?" ”

Chen Yi sighed: "I can't sleep, the murderer ruined three families, Zhou Yumeng hugged his mother's tombstone and cried at night, can this picture be forgotten?" This, he must be caught. ”

Fang Shuyu: "Only after resting can you keep a clear mind, go back to sleep and check again." ”

Chen Yi shook his head: "No, the provincial department has just sent the file of the Imperial City case, I want to go through it immediately to see what I have gained, in case there are major clues, it is not good to delay time." ”

Fang Shuyu knew that it was impossible to persuade Chen Yi away, so he could only ask the other party to sleep quickly after reading the dossier.

Chen Yi agreed, and after Fang Shuyu left, he continued to look through the documents on the desktop.

Xia Qingwen, a relatively neutral name, is twenty-one years old, a native of Imperial City, a student of Imperial Normal University, majoring in fine arts.

Four years ago, Xia Qingwen's body was found in a cemetery in the imperial city and died in front of his brother's tombstone.

The Xia family only has a son and a daughter, and the death of their son has made them grief-stricken, and now that their daughter has been killed, the two collapsed on the spot, and they went directly to the hospital due to excessive sadness.

The scene of the crime was shocking, Xia Qingwen's throat was pierced, and a large amount of blood from the arteries flowed out and stained his clothes and the ground.

After on-site investigation and a comprehensive autopsy, it was determined that Xia Qingwen was killed in a conscious state, without any drug ingredients in his body, and there were no defensive injuries on his body.

Raid and kill.

It was judged that the murderer suddenly attacked, causing Xia Qingwen to be defenseless, and finally died of excessive blood loss.

Xia Qingwen's face still had dry tear stains, he should have cried in front of his brother's grave, and his expression in the state of death was a mixture of sadness and fear.

Just in front of Xia Qingwen's corpse, a photo of his younger brother with a smile on his face was still hanging there.

He just "watched" his sister being killed, watching his sister shed her blood and die, but he couldn't do anything, it was a human tragedy.

If there were ghosts in the world, the murderer would definitely be torn apart by Xia Qingwen's younger brother the moment he launched the attack.

"Damn."

Seeing this, Chen Yi frowned, couldn't help but scold, took the cigarette case, took out a cigarette from it and lit it, and continued to look down.

The investigation of the murder began immediately, and the technical investigators carried out a carpet search around the scene, and all the nearby surveillance cameras were checked frame by frame, and many days passed, and nothing was gained.

Xia Qingwen's interpersonal relationship has been investigated, she has a boyfriend in college, her boyfriend has been interrogated many times, and the people who have intersected on both sides have not been let go, and there is still no gain.

This girl is an ordinary college student in the Imperial City, with a simple life and no enemies, except for the sudden death of her younger brother, there have been no changes in her life since she was a child.

This case made Geng Jianqing of the Imperial City Bureau and the Police Department puzzled, and he suddenly launched an attack without seeking wealth or sex, and he didn't know what the murderer thought.

After reading the detailed file, Chen Yi snuffed out the cigarette in his hand and changed to himself, and the possibility of solving the case at that time was not very great.

The cigarette was seamless, and Chen Yi lit another one.

"Xia Qingwen of the Imperial City is attacked and killed, Bi Xuelan of Ningcheng is kidnapped, and Cai Wenwen of Yangcheng is made an appointment to rent a house in the community......"

Apart from the same modus operandi, there is no common denominator, and there is no other connection.

The secrecy of the murderer's machine was beyond Chen Yi's imagination, even if he had two lifetimes of experience in solving cases, he couldn't figure out why the murderer did this at this moment.

"Paint."

"Xia Qingwen is just an art major, and understanding art is like a classmate who understands computers, and painting means little to her."

"Cai Wenwen is different, Cai Wenwen really likes painting and is eager to make it a career."

Bi Xuelan...... Bi Xuelan didn't know how to draw, and her daughter learned to paint.

"Is the motive really related to painting? Isn't it too far-fetched to connect? ”

Chen Yi cannot use painting as the main direction of inference, because once it is far-fetched, there will be many commonalities and a high error rate.

"Even if the motive has nothing to do with painting, the intersection may have something to do with painting?"

This is more reliable, Chen Yi noted this possibility.

"Where the crime was committed...... Maybe it's creation, Xia Qingwen is a college student, it's hard to find a chance to do it, her brother's tomb is the only safe place, Cai Wenwen has an introverted personality and a strict family education, she is a good girl, if you want to do it, you have to ask her out. ”

"Bi Xuelan is a stay-at-home mother, and her daily life is very simple, and it is difficult to make an appointment, so she can only be kidnapped."

"Targeted?"

"Which of these three female victims attracted the killer? What else can it be? ”

Chen Yi felt a headache.

Xia Qingwen.

Bi Xuelan.

Cai Wenwen.

There's nothing special about the name, but it can't be because the name is three words, right? It's.

He turned on his computer and tried to search for the names of the three people, trying to connect them, but found that it was useless.

"What about the intersection on the Internet?"

Chen Yi thought of this possibility, in the modern information age, it is normal for people from all over the world to have contact with each other.

Three cases flashed through his mind, and he tried to find suspicious clues, but before he knew it, sleepiness hit him and he collapsed on his desk.

At dawn, Fang Shuyu, who came to the city bureau, pushed Chen Yi's office open for the first time, and was very distressed to see the other party lying on the table tiredly.

She didn't wake up Chen Yi and went out to pack breakfast.

At the same time, Qin He of the Imperial City and Xie Yunzhi of Ningcheng received a call from Geng Jianqing, ordering the two of them to immediately rush to the Yangcheng Provincial Department with the main personnel of the year, and the 405 task force was about to be established.

Geng Jianqing and Fang Songping have communicated, and the leader of the task force is Qin He, the head of the Imperial City Criminal Investigation Corps, and the deadline is three months to fully investigate, and if the case is not solved after the expiration, it will be disbanded on the spot, but the case will continue to be investigated, and each city will be responsible for it until the murderer is caught.

For three months, the three cities conducted a joint investigation, regardless of the results, and only did their best, and Geng Jianqing would also stay in the special case team and exist as a criminal investigation consultant.

The new case represents a new clue, and the investigation begins in Yangcheng.

After receiving the call, Qin He and Xie Yunzhi were shocked, they didn't expect the backlog of cases to suddenly turn into a serial case, the two did not hesitate, immediately arranged the work of the team, and led people to Yangcheng quickly.

At nine o'clock in the morning, Chen Yi was woken up by the ringing of his mobile phone, he sat up abruptly and picked up his mobile phone, and found that it was Geng Jianqing calling.

"Hello? Uncle Geng. ”

Geng Jianqing: "Just woke up from the sound? ”

The voice of the person who has just woken up is very special, and no matter how hard you try to hide it, it is difficult to fool the past.

Chen Yi: "Well, I just woke up, I slept in the city bureau last night, and I watched the imperial city file." ”

Geng Jianqing: "It's hard work, eat and eat spiritually, go to the provincial hall before eleven o'clock, Qinhe Xie Yunzhi is already on the way, and the case will be merged." ”

Chen Yi: "Okay, understood. ”

Hanging up the phone, he saw the breakfast on the table and knew that it should be sent by Fang Shuyu.

After eating casually, he called Shi Xin.

"Lao He, I will go to the provincial department in a while, I should set up a task force, and the rest of the team's work will be handed over to you first."

It is impossible for the detachment to keep an eye on the current case, it is normal for multiple cases to be carried out at the same time, and after three months of special investigation, someone needs to be in charge of the team, when the new deputy detachment leader will probably not enter the task force, at most he will be looked for when he needs help during the period.

Shi Xin promised: "Okay, don't worry." ”
