It's a pity that it backfired, and after tracking from multiple directions on the Internet, the suspect still couldn't be locked.

Jiang Wu sat in front of the computer and scratched his ears and cheeks, "What method did this dog use, but there was no trace at all." ”

Xu Shu knew that this clue would not appear easily, so he changed his angle, and Liujiangwu continued to look for the identity of the person who provided sleeping pills, and the rest figured out why the water delivery worker used sleeping pills.

The murderer has an extreme personality and should not be afraid of being exposed. On the contrary, if someone finds the scene of the crime, it will cause a greater sensation and follow his wishes.

Xu Shu and Jiang Qingrui went to Chen Jingjing's house again, and just arrived on the floor, they found a lady standing in front of the cordon.

"Do you know this household?"

Jiang Qingrui walked next to the woman, the room was not closed, and the whole view of the living room could be seen from this position.

"Who are you?"

The woman turned to face the two of them.

Her facial features are gentle and generous, her temperament is friendly, her height is about 1.7 meters, she wears a camel-colored windbreaker to modify her figure, and she wears a silk scarf of the same color around her neck.

"Police."

The woman showed a surprised expression and whispered, "No wonder I saw a cordon, it turned out that something was wrong." ”

"What do you have to do with this household?" Jiang Qingrui asked again.

"I'm their psychiatrist."

They?

Jiang Qingrui keenly captured the key words, "Are you free now?" We have something to know about this household. ”

The psychiatrist was very cooperative and followed him back to the Public Security Bureau.

"Name."

"Qin An."

"Occupation."

"Psychiatrist."

Jiang Qingrui took notes on the computer, and Xu Shu asked.

"Who does the 'they' you just said include all about?"

Qin An pulled the hair from his ears behind his ears, "Chen Qinghua, Ren Shuo." ”

Jiang Qingrui immediately remembered that Ren Shuo was a water delivery worker.

"Tell me more about the cause and effect of the two of them coming to you for treatment."

It stands to reason that a psychiatrist cannot reveal a patient's condition, but the person is dead, and the other is also a suspect.

Qin An didn't know what was happening now, but her intuition told her that it was important.

Clearing her throat, she succinctly explained the process of the consultation.

Chen Qinghua and Ren Shuo came together, both of whom suffered from severe anxiety disorders for unknown reasons, and they came to seek help and hope to improve.

Chen Qinghua didn't come much, and after chatting, he only knew that he liked his dog very much, and the topic always revolved around animals.

"Oh yes." Qin An remembered a small episode. "He once complained to me many times about his neighbor for a while, because the dog barked late at night, the neighbor was very dissatisfied and asked him for a theory."

Ren Shuo often came to consult, but most of them were just small talk afterwards and didn't involve himself too much.

"From the beginning to the present, Ren Shuo has always had the trouble of lack of money."

Qin An only knew so much.

After the inquiry, Qin An strode away, Jiang Qingrui watched her back fade away, and a suspicion in her heart slowly magnified.

"You've found out, too."

Xu Shu didn't know when he appeared behind her, "According to Qin An, Ren Shuo has received psychological treatment many times, and the cost is very high each time, but at the same time, he complains about the financial pressure. ”

The two agreed that this was a noteworthy suspicion, and Xu Shu sent several police officers to monitor Qin An and pay attention to what she could do.

After a day, Qin An was at home and at the company, and there seemed to be nothing suspicious, but Xu Shu did not withdraw and let the police continue to supervise.

At dinner time, Jiang Wu hurriedly ran to the cafeteria, "Team Xu! There's movement in the group! ”

Jiang Qingrui hurriedly ate a few large bites of rice and went to see the news with Xu Shu.

After a few days of dead group chat, someone suddenly sent a message, "Who still has a purchase channel, hurry up and share it with my brother, use it urgently!" ”

Jiang Wu's fingers crackled and pressed the keyboard, "I checked his IP address as soon as I saw the news, and it wasn't far from us." ”

Xu Shu gave an order, "Go, go to the police!" ”

Within half an hour, a gangster-looking young man sat in the interrogation room.

"You asked for medicine in the group, right?"

After receiving an affirmative answer, Jiang Wu's face was a lot more relaxed, and he was worried about it in the past few days.

"Do you know who the person who provided the medicine was?"

The thugs didn't calm down at the sudden appearance of the police, and their eyes were glazed, "I don't know, a package will appear in a few days after the transfer." ”

Xu Shu has already sent someone to check, the account IP is flexible and changeable, the address is random, and it is completely false.

"What are you buying medicine for?"

The thugs were silent, bowing their heads and not squeaking.

"We don't have much time to spend with you now, so if you don't say anything, let's detain it first."

The two sides were deadlocked for five minutes, and Jiang Wu opened his mouth to say to him.

The gangsters obviously couldn't accept such an outcome, and finally broke down, "Use it." ”

"I don't know how to use it yet!" Jiang Wu slammed the table, "Don't give me anything to avoid the heavy!" ”

The thug startled a spirit, "I'm here to do that." ”

"Make it clear!"

The gangsters stumbled and said the cause and effect.

It turned out that he heard that there was a way to play in the red light district, which made it more exciting to do things after stunting people, so he also wanted to try it, so he asked for sleeping pills in the group.

Jiang Qingrui suddenly thought of Ren Shuo's previous interrogation, he said that there are often people in the group who use sleeping pills to do bad things, including trading, which is the default behavior of both parties, just give money afterwards.

"I've got a target."

The gangster gritted his teeth, he was unwilling, "I already stunned that woman, but I didn't expect to be taken first." ”

Jiang Wu had already found out in the chat records that the gangster had once said hello to the deceased.

"Who are you targeting?"

"Song Yunsha."

Jiang Wu had already put her on suspicion, and he was not surprised by this, "What about the person who is one step ahead of you." ”

"Ren Shuo."

The gangster's answer was unexpected, and it was actually related to the water delivery worker.

According to the thugs, he was already undressing, and the door suddenly opened, and Ren Shuo rushed in and pushed him out.

Xu Shu interrogated Ren Shuo again.

Ren Shuo replied without hesitation, "There is such a thing." ”

He didn't say half a word in the previous interrogations, Jiang Qingrui was full of anger, "What happened after that." ”

Ren Shuo had an indifferent attitude, he had already accepted staying at the police station, "I just didn't give money, a group of people from the red light district came to my house to scold me, and I complained a few words in the group." ”

"And then." Jiang Qingrui knew that things were definitely not so simple.

"Chen Qinghua is using this matter to blackmail me." The gangster was displeased, "Let me do something for him, and if he refuses, he will publicize that I am a prostitute and will not give money." ”

Jiang Qingrui had a flash of inspiration, "Did he let you put sleeping pills in other people's water?" ”

"Yes."

The mystery was solved, and Xu Shu called the bustard.

"Do you know what happened between Song Yunsha and Chen Qinghua?"

"I didn't have a few words with her before I knew she had scolded the man's dog." ”
