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

In the case handling hall, while everyone was relieved, they also had doubts about the motive of the crime and Hong Shanshan's physical condition.

Let’s talk about the motive first.

The victim Peng Mo was Dong Yubo's best friend. Why did Hong Shanshan, Dong Yubo's girlfriend, kill Peng Mo after she broke up with Dong Yubo?

Not only that, but the crime location was chosen at Dong Yubo's home.

What's more, Peng Mo's body was glued under Dong Yubo's bed with strong glue, causing Dong Yubo to sleep back to back with his best friend for a whole day.

The behavior is incomprehensible. Does it have any special meaning? Or simply to take revenge on Dong Yubo.

If it's revenge, why?

This incident will probably leave a considerable psychological shadow in Dong Yubo's heart. I wonder if he will be able to fall asleep in the future and whether he will dare to sleep on the bed.

At least I don’t think I would dare to use a high-leg bed.

Let’s talk about Hong Shanshan’s physique.

Hong Shanshan is 1.65 meters tall and weighs only about a hundred pounds. She is not the big-bodied and round-waisted type.

On the surface, his personality seems to be relatively quiet and weak.

To be honest, it's a bit strange that such a girl chose such a violent way to kill and even fixed the body under the bed with great effort.

Let alone women, even a relatively fierce man would need a lot of courage and a very necessary reason, such as the urge of huge hatred, to smash a person's head with a hammer.

So, what is Hong Shanshan’s psychological journey?

"Sister Jiang, how long will it take for the taxi driver to arrive?" Chen Yi looked at Jiang Xiaoxin.

Jiang Xiaoxin said: "About half an hour."

She has contacted the taxi driver who picked up Hong Shanshan again, and the taxi driver said that the cash received was not spent and was kept in the car.

Nowadays, electronic payment is universal, and very few people use cash, which is quite inconvenient.

Chen Yi nodded slightly and said, "Sister Jiang, check Hong Shanshan's mobile phone to see if there is any order record for purchasing the same hammer online."

Jiang Xiaoxin: "Okay."

Zhuo Yun moved a chair and sat next to Chen Yi, watching the other person click on the map on his mobile phone.

"Any clues?" he asked.

Chen Yi searched the map, zoomed in from time to time, and said: "Hong Shanshan's movement trajectory that day was as follows: she first went to the bar where Dong Yubo worked, chatted with Wu Lin for a while, and then left. After changing her clothes, she went to Dong Yubo's bar. Home."

"Now we can think that Hong Shanshan may have two purposes for going to the bar. The first is to see Dong Yubo, and the second is to confirm whether he is at work."

"When I asked Dong Yubo yesterday, there was something wrong with his demeanor and reaction, especially after seeing the figure in black. I think he suspected or was sure that the person's identity was Hong Shanshan."

"Now there is one more thing. Where did Hong Shanshan change her clothes? If it can be found, the chain of evidence will be connected. The premise is that the surveillance can capture it."

Zhuo Yun: "You will know if you interrogate Hong Shanshan directly."

Chen Yi: "Being idle is also idle, and she may not necessarily say it."

Zhuo Yun nodded, said no more, and looked at the map with Chen Yi.

"Bar, Haiyun Apartment, more than an hour."

Chen Yi marked these two locations and turned to look at Zhuo Yun: "Do you think it's possible in a milk tea shop?"

Zhuo Yun stared at the map: "It's possible. Although it's not along the way, it's not far. One hour is definitely enough."

"Xiaoxin is busy. I'll go to the network supervisor and communications department and ask someone to check it out."

Chen Yi: "Okay, between nine and ten o'clock the night before yesterday."

Zhuo Yun: "I'll go right away."

After saying that, he stood up and left, and Chen Yi also put away his mobile phone.

About half an hour later, the taxi driver arrived and brought the cash the suspect paid at that time.

In the past half month, this was one of the few times he had received cash, so he remembered it very clearly and there was no mistaking it.

The note was immediately sent to the technical department for attempts at fingerprint extraction.

"Chen Yi, no."

After checking for a long time, Jiang Xiaoxin turned to greet Chen Yi.

Chen Yi stood up and walked over.

"There's none?"

Jiang Xiaoxin: "Indeed, there are three shopping apps on Hong Shanshan's phone. No order to buy a hammer was found, and there were no deleted orders."

"Did you buy it at the hardware store?"

Chen Yi looked at the time. If he went to visit again at this time, some of the hardware stores he visited were almost closed, so he could only put it on hold for now.

Maybe Hong Shanshan will tell them the answer.

Six o'clock in the evening.

The surveillance investigation results and fingerprint extraction work are all completed, and the evidence all points to Hong Shanshan. The suspicion of the other party's murder can basically be said to be 100%.

At this moment, Hong Shanshan was immediately taken from the detention room to the interrogation room again.

The difference from last time is that this time he was handcuffed.

Seeing the hammer on the table in front of Chen Yi, Hong Shanshan's expression changed and she became suspicious.

"Hong Shanshan." Chen Yi said, "Your understanding of counter-reconnaissance is a bit one-sided. Please tell me why and how you killed Peng Mo."

Hong Shanshan swallowed and gritted her teeth: "I didn't kill him."

boom!

Chen Yi slammed the table and said coldly: "Hong Shanshan!!"

Hong Shanshan was startled and trembled all over.

Chen Yi stared at her: "You have figured it out, this piece of money has your fingerprints on it, and the owner of the fingerprints is the suspect in this murder case."

"We police officers never believe in coincidences. Don't say that this money was circulating in the crowded Yangcheng and then happened to be in the hands of the taxi driver."

"Didn't you say you spent the whole night shopping? Why did you go to Dong Yubo's house? Ah?!"

Hong Shanshan said in a panic: "No, no... I really didn't kill him. That person was definitely not me."

Chen Yi shook his head, stood up, picked up the surveillance screenshot and placed it in front of Hong Shanshan. Hong Shanshan looked down.

That was his figure entering the milk tea shop. When he came out again, he put on a black coat and held a hat in his hand.

"Hong Shanshan, is your vision okay? Isn't this you, is it me?"

Hong Shanshan looked at these photos blankly, and cold sweat began to break out on her forehead.

"I...I really didn't kill him!"

Chen Yi: "I asked you who the person in the photo is!"

Hong Shanshan: "It's...it's me, but I didn't kill him!"

Chen Yi tilted his head and looked into her eyes, and said in a strange voice: "Hong Shanshan, are you mentally okay? Do you know what you are talking about?"

"I ask again, was it you who killed Peng Mo!"

Hong Shanshan became more and more nervous, her face turned pale, and she looked pitiful: "I...I seem to be killing...no! I didn't kill him! He was not killed by me!"

After saying that, she hugged her head and looked a little painful.

Chen Yi frowned. She now suspected that there was something wrong with Hong Shanshan's mental state.

After waiting for a while, when Hong Shanshan gradually calmed down, he raised his hand and put it on the other person's shoulder.

This action made Hong Shanshan tremble.

"Hong Shanshan, do you have schizophrenia?" Chen Yi's voice was very soft.

Hong Shanshan was confused: "Schizophrenia? No, you are the one with schizophrenia! Who are you talking about!"

Chen Yi: "Let me ask you one last time, did you kill Peng Mo?"

Hong Shanshan: "No!"

Chen Yi stared at her for a while, then turned to leave the interrogation room.

When he reached the door, he stopped, turned around and said, "Do you love Dong Yubo?"

This question made Hong Shanshan stunned for a moment, then she lowered her head and said, "I love him very much."

Chen Yi opened the door and left.

In the case-handling hall, everyone gathered around and talked a lot. They all saw the interrogation just now.

"Captain Chen, is this woman a good girl?"

"It sounds like it to me. My thinking feels a bit confusing. Why don't I go and get it checked out."

"Maybe he's just faking it, right? To escape legal punishment? Mental illness can be exempted from punishment depending on the circumstances."

"No, no, you are talking about a mental patient who has lost the ability to distinguish and control his behavior. This woman was very calm. She fixed the body under the bed and cleaned the scene and fingerprints. Do you think this is a mental patient?"

Listening to the voice in his ears, Chen Yi lit a cigarette.

"Okay, don't guess. We'll find out after checking." After a while, his voice sounded, "It's definitely impossible to lose the ability to distinguish. She was very conscious when she killed someone. Judging from her reaction just now, she may have a dual personality."

"I think it's too much to plead guilty. I'll try to find a way to force out her other personality."

Zhuo Yun on the side nodded: "I also think it is a dual personality, and it seems that the memories are interconnected?"

Chen Yi took a puff of cigarette: "Dual personality is more complicated. Generally speaking, the personality has independent memory and the memory is independent, but there are also situations where memory is shared."

"Her confused thinking indicates that memories are not completely shared and biological inheritance can be ruled out."

Zhuo Yun: "In other words... it was formed the day after tomorrow?"

Chen Yi nodded: "Most of them are acquired, especially childhood abuse and witnessing traumatic events or deaths, which leave a huge psychological shadow."

"It's a defense mechanism."

Dual personality itself is a defensive symptom group, in which psychological trauma plays a decisive role, causing patients to use dissociated personality to defend themselves.

The personality separated in this situation often has a strong dark side and an indestructible psychological quality.

This can explain why Hong Shanshan, who looks weak on the surface, can smash Peng Mo's head mercilessly and calmly handle the scene.

Listening to the conversation between Chen Yi and Zhuo Yun, everyone looked at each other in shock. This was the first time they had encountered such a suspect.

"Then we have to start with the motive of committing the crime and Hong Shanshan's early experience." Zhuo Yun said, "It seems that we still need to investigate, the case is not over yet."

Chen Yi: "Yes, dual personality is not an antisocial personality. It is impossible to kill people for no reason. They must be stimulated, and it is most likely trauma-related stimulation."

"Dong Yubo, we still have to ask and find out where he is now."

"Brother Yun, go and bring him here."

Zhuo Yun nodded: "Okay, I'll do it right away."

On the other side, Qin Fei may have been influenced by the movie and had an unknown fear of dual personalities, but he did not show it.

It's not that I'm afraid, and there's no need to be afraid. I just feel that a girl can transform from weak and innocent to ruthless and cold. The image is too strong.

It doesn't matter if I take it out on its own, I'm just afraid of comparison.
