The Municipal Public Security Bureau.
After Han Bin and the others returned to the Municipal Public Security Bureau, Wang Xiao and Jiang Yang also rushed back.
Ma Jingbo gathered everyone for a summary meeting.
Han Bin briefly described the contents of the supplementary statement.
Ma Jingbo pondered for a moment, "Ren Lingling is the only witness, and her testimony is very important. Similarly, if she perjured herself, it will affect the direction of the investigation."
"So in terms of the investigation, we should focus on evidence. I checked the surveillance footage you brought back, and there were a few people in the vicinity during the time of the crime. Li Qin, Bao Xing, you two check the identities of these people."
"Yes."
"There's one more thing I want to say. The forensic doctor collected some skin tissue from the fingernails of the deceased, and it's very likely that it was a self-defense injury from the fight with the suspect."
"I've already asked the technical department to do a DNA comparison in the database. If the murderer has a criminal record, we'll have the results soon. "
Ma Jingbo then looked at Wang Xiao on the side, "Tell me about the investigation you guys went to the school."
Wang Xiao cleared his throat, "According to our investigation, Ren Lingling and Ma Jinlu are indeed students of the Qindao Business School, and the two are indeed a couple. The teachers and classmates of the school can testify to this, and the two have always been in a good relationship."
"However, the two of them aren't good students, and they often skip classes. Because they're usually generous and often treat people, they have a good relationship with their classmates. "
"I also found a clue. According to Ren Lingling's roommates, Ren Lingling's father will come to the school to see her in the next two days. He'll bring some local specialties for everyone to eat. "
Hearing this, Ma Jingbo interrupted, "Han Bin, have you seen Ren Lingling's father?"
"No."
Ma Jingbo knocked on the table with his finger, "If Ren Lingling's father is really in Qindao, it's reasonable for him to not show up after such a big thing happened to his daughter."
Li Qin guessed, "Could it be that Ren Lingling doesn't want her family to know that she's in the sex trade, so she didn't tell her father?"
Han Bin took over the conversation. "Her father made a special trip to Qingdao to see her. Regardless of whether she wants to or not, her father has to meet her since he's here. If she doesn't see her father, her father will be more worried. "
"Also, the timing of his father's visit to the island is a bit coincidental. If his father finds out that his daughter is in the sex trade, I think everyone knows what the consequences will be."
Ma Jingbo ordered, "Qianqian, investigate Ren Lingling's father and see if he came to Qin Island."
"The rest of you, check the surveillance cameras around the scene to see if there are any other suspicious people."
"Yes." Everyone split up.
After the meeting, Han Bin went to the technical department and asked them to compare Ren Lingling's DNA with the dandruff collected from the victim's fingernails.
Ren Lingling played an important role in the case. Only by eliminating her as a suspect could her statement be used.
…
Half an hour later, Huang Qianqian hurried back to the office.
"Captain Han, I've located Ren Lingling's father." Huang Qianqian took a deep breath and continued, "Ren Lingling's father is called Ren Zhongyuan. Yesterday, he took a train to Qin Island and arrived at around eight o 'clock at night."
"There's an even more important clue. Ren Lingling's father bought a train ticket to leave Qin Island at noon, and the departure time is 7: 30 pm."
Han Bin analyzed, "His daughter is in such a big trouble, but her father left in a hurry. It doesn't make sense."
Bao Xing rubbed his palms together. "Captain Han, what else is there to say? Let's arrest him."
Han Bin glanced at his watch. It was already five o 'clock in the afternoon. "Bao Xing, go to the technical department and ask them to locate Ren Zhongyuan. I'll report to Captain Ma."
"The rest of you, pack up and get ready for the arrest."
…
Qin Island's new train station.
A middle-aged man in his forties sat on a bench with his hands in his pockets. His eyes were a bit dull, and he would occasionally look up at the clock in the hall.
A man in his twenties walked over with a cigarette in his hand. "Brother, lend me a lighter."
The middle-aged man was stunned for a moment before he took out a lighter from his pocket. Just when he was about to light the cigarette for the man, two people rushed over and held his hands down.
"Police, don't move!"
The middle-aged man was stunned. He didn't resist and only reacted after he was handcuffed. "What are you doing? What right do you have to arrest me?"
The man who asked him to light the cigarette was Han Bin. "What's your name?"
"Ren Zhongyuan."
"Where are you from?"
"Nanbin."
"What are you doing here?"
"I … I'm here for a vacation. Isn't this a tourist city? It's normal for me to come here. "
"You arrived last night. Aren't you in too much of a hurry to leave today? What kind of attractions can you visit? "
"I … I have something to do at home. I'm in a hurry to go back."
"Does Ren Lingling know what's going on at home?"
Ren Zhongyuan's face was extremely ugly. "My child is still in school. I don't want her to worry about some things."
"Does Ren Lingling know you're coming to Qin Island?"
"Nope."
"Nonsense. Ren Lingling's classmates all know you're coming to Qin Island. You're still lying."
This wasn't the place to ask questions. There were already a lot of people around. Han Bin waved his hand. "Take him away."
After a few simple questions, Han Bin was already sure that there was definitely something wrong with Ren Zhongyuan. He was extremely panicked.
After returning to the police station, Han Bin immediately interrogated Ren Zhongyuan.
Ren Zhongyuan sat on the interrogation chair with his head lowered. His expression couldn't be seen clearly. His hands were clasped together.
Han Bin knocked on the table. "Raise your head."
Ren Zhongyuan slowly raised his head. "Officer, why are you arresting me?"
"Did you see Ren Lingling during your trip to Qin Island?"
"No."
"You came all the way from Nanbin to Qin Island and didn't even have time to see your daughter. Do you think that makes sense?"
"I wanted to see her. But I had something to do at home. I didn't have time. "
"What happened at home?"
"My mother-in-law is seriously ill. My wife called and told me to go back immediately."
"When did your wife call you?"
"Around eight this morning."
"What's your wife's phone number?"
"I … I can't remember."
"You can't even remember your wife's phone number?"
"I can't remember."
Han Bin flipped through his phone on the table. "You didn't call me between eight and nine this morning. You're lying."
Ren Zhongyuan's hands trembled. "I might have remembered the time wrong."
"Bang!" Bao Xing slammed the table. "What do you mean you remembered wrong? Are you messing with the police? Let me tell you, don't play any tricks. We have records. "
"I'm not playing any tricks. It's my first time at the police station. Maybe I'm too nervous."
Han Bin said, "You don't have to be nervous. Just answer my questions."
"Do you know Ren Lingling?"
"Yes."
"What's your relationship?"
"She's my daughter."
"Where were you between 9: 30 and 11: 30 last night?"
"I was at a hotel."
"Which hotel?"
"Hotel Yan Bin."
"Are you sure you didn't leave the hotel during this time?"
Ren Zhongyuan lowered his head. "I … I can't remember."
"Then think about it. I want an accurate answer."
"I think I went out."
"What did you do?"
"To eat."
"Where did you eat?"
"I can't remember."
"You can't remember what happened last night? Who are you kidding?"
"I ate at a roadside stall. It's my first time here, so I can't really remember."
"Tell me the approximate location."
"It's on a street not far from Yan Bin."
"What did you eat?"
"Green pepper and shredded pork with rice."
"What time did you leave and return to the hotel?"
"I came out to have fun. I wasn't in a hurry, so I didn't pay attention to the time. I cleaned up at the hotel and came out to eat. After eating, I walked around the neighborhood. I haven't been to Qin Island many times, so everything was new."
This kind of perfunctory answer sounded like he was trying to hide something. If he really wanted to clear his name, he wouldn't be so perfunctory.
"Did you have any companions while you were in Qin Island? Who did you meet?"
Ren Zhongyuan shook his head. "I'm unfamiliar with this place and don't know anyone. I'm just by myself."
"You arrived last night and left tonight. Although it wasn't a long time, it was enough to see your daughter. Why didn't you go see her?"
"I wanted to see her, but my wife wouldn't let me. My mother-in-law has always kissed my daughter since she was a child. If my daughter knew that my mother-in-law was sick, she would definitely be worried. I was also afraid that I would spill the beans, so I didn't go see her. "Ren Zhongyuan sighed as if he was regretful.
"I wanted to wait for my mother-in-law to recover and bring my wife to see my daughter."
The more Han Bin heard this, the more he felt it was fake. Han Bin hated this kind of liar the most. Every time he lied, the police would spend many times more manpower and resources to investigate. In the end, it would only prove that it was a lie and delay the progress of the investigation.
