Seeing the crime scene flashbacks made me the darling of the police station.

Chapter 138 There is a fourth person.

Chapter 138 There is a fourth person
"Yes, I've come to this point because of a man who isn't worth entrusting my life to."

Zeng Shuang's voice was lifeless.

“I’ve been suffering from insomnia because of that incident, and over time, I’ve developed some health problems.” Zeng Shuang said, her head down. “My boyfriend cared about me a lot and took me to see doctors and psychologists, but I still didn’t get better.”

"That incident was like a festering wound in my heart. It wouldn't heal; instead, it got worse and worse, growing bigger and bigger. One day, it would rot through my heart, and I would die."

“I wanted to cut out the rotten flesh. No matter what, if I cut it out, I might still have a glimmer of hope. So I told my boyfriend, but he couldn’t accept it and broke up with me.”

“I can understand it. Everyone has their own choices, and I don’t blame him. I also felt like I could finally catch my breath and get some temporary relief during those days.”

“But what happened?” Zeng Shuang said, tears welling up in her eyes. “My boyfriend’s computer is at my place. I called him to ask him to take it away, but he thought I was calling to try and get him to stay.”

“He called me a bitch and a slut on the phone, saying I seduced my ex-boyfriend. I never knew that the man I had loved for several years could say such nasty things. He said I was dirty and disgusting, and that I had kept what happened from him and not told him.”

"She was still close to him, which made him feel extremely disgusted."

Zeng Shuang lowered her head, tears streaming down her face.

Chu Xingrou handed her a tissue.

Zeng Shuang lowered her head and wiped away her tears: "The rotten flesh has been removed, but the wound has not healed and continues to rot."

“This will drag me down to my death. I can’t get rid of it, and I won’t live long. So, I want to kill those two scumbags before I die!”

Zhuang Yanzheng asked, "How did you get into the boys' dormitory?"

“There are no security cameras at the side entrance of the dormitory building,” Zeng Shuang said.

"How did you know?" Zhuang Yanzheng asked again.

“I found out by asking around. You can find out about things like that easily by asking around,” Zeng Shuang said. “That door lock is basically just for show. It can be opened with a little prying with a wire. They often use the side door at night.”

When they visited and inquired, none of the students mentioned this matter.

"Put on a hat, loose clothes, and a mask. Anyway, nobody knows anyone, and it's nighttime. There aren't many people in the dormitory corridors. I didn't encounter anyone in the corridors or stairwells."

"How do you know they're all in the dorm?" Zhuang Yanzheng asked. "Wen Zhuoyu's parents said he spends most of his time at home and stays in the dorm relatively little."

“We ran into each other the day before,” Zeng Shuang said. “Wen Zhuoyu and his roommate humiliated me again. I pretended to be scared and told them to stop talking. I told them I could go to the dorm to keep them company. So we set the time for that night.”

What happens after you get to the dormitory?

“We had some drinks,” Zeng Shuang said.

"Is it just alcohol? What's in the alcohol?" Zhuang Yanzheng asked.

“There’s medicine,” Zeng Shuang said. “It’s the same medicine they gave me last time, which I put in their wine.”

"Do you know what kind of medicine that is?" Zhuang Yanzheng asked.

"I don't know," Zeng Shuang said. "I tricked Wen Zhuoyu into taking it out, and then secretly put it in their wine."

Chu Xingrou frowned slightly.

Zhuang Yanzheng looked at her, paused for a moment, and then asked, "So you used the medicine that Wen Zhuoyu had?"

Zeng Shuang nodded.

"Then?"

“After that, once they passed out, I killed them with a fruit knife,” Zeng Shuang said. “I knocked over everything that could be pushed over in the dormitory, and I was worried that other dormitories would hear, so I was very careful. Then I faked the scene as if they had killed each other in a fight.”

"Where's the blood in the sink?" Chu Xingrou asked.

“I was wearing gloves, but I got blood on my wrists, so I washed them before leaving,” Zeng Shuang said. “After washing my hands, I remembered that if they were fighting each other to death, how could there be blood in the bathroom sink? So I used the hydrogen peroxide from their dorm room to clean the sink.”

“I’d heard before that the hydrogen peroxide in hydrogen peroxide could clean bloodstains so the police wouldn’t find them,” Zeng Shuang said. “After everything was taken care of, I took the wine and glasses and left the dormitory.” “Which gate did you leave through? When did you leave?” Zhuang Yanzheng asked.

“We left from the playground; you can jump out from there,” Zeng Shuang said. “I don’t remember exactly when.”

"You studied economics in college," Zhuang Yanzheng asked. "Did you study medicine later?"

“No.” Zeng Shuang shook her head.

"No medical training? The wounds on the corpses—a back wound right in the heart, an abdominal wound piercing the liver—are almost identical in location on both bodies," Zhuang Yanzheng asked. "No medical training, yet such skillful technique?"

Zeng Shuang blinked her eyes slightly: "I don't know, it might be a coincidence."

As Yan Cheng listened to her words outside the interrogation room, something suddenly occurred to him.

He took off his headphones.

Su Miaoyi turned her head to look at him.

"I'm going to the dissection room," Yan Cheng said, and then left.

Su Miaoyi looked back into the interrogation room.

Zhuang Yanzheng then asked, "Was the fruit knife you used to kill someone also from Wen Zhuoyu's dorm?"

"Mm," Zeng Shuang replied.

"You just said you felt you couldn't go on living and wanted to kill them both before you died," Zhuang Yanzheng asked. "But if that's the case, why did you stage it as if they fought and killed each other?"

“I suddenly got scared and did it,” Zeng Shuang said. “But then I thought about it and realized that the drugs in their bodies would definitely be detected. The fight was not a valid argument, and they would find me sooner or later.”

Zhuang Yanzheng didn't say anything more.

Seeing that he intended to remain silent, Chu Xingrou also kept quiet.

As Zhuang Yanzheng expected, Zeng Shuang took the initiative to speak.

“I killed them, I did it all,” Zeng Shuang said. “They got what they deserved, I don’t regret it. I traded my life for their two lives, it was worth it.”

Zhuang Yanzheng didn't say anything or ask any more questions, and left the interrogation room directly.

Chu Xingrou found it very strange, but she didn't say anything and followed them out.

Su Miaoyi took off her headphones and went to find them.

“Captain Zhuang, there are many loopholes in what she said,” Chu Xingrou said.

“Okay,” Zhuang Yanzheng said. “Go and interrogate her again in a little while.”

"Yes," Chu Xingrou replied.

Zhuang Yanzheng said, "Go tidy up first, and go in and ask her in half an hour."

"Okay." Chu Xingrou left.

“She won’t say,” Su Miaoyi said. “She was too well prepared. She guessed right on every question and gave answers she had prepared in advance.”

“It’s hard to find a breakthrough with someone who’s determined to die,” Zhuang Yanzheng said. “I still think that fruit knife is the key.”

As he was speaking, his phone rang.

It was Yan Cheng who called.
