The technical department was also very busy, and Chen Yan left after speaking.

Li Qin said, "Looking at it this way, Salman may indeed have been planted."

"When Shah Rukh comes, make a transcript for Shah Rukh. As long as he can prove that Salman did drink beer that night, plus Zelay’s testimony, and the evidence found by the technical department, he can temporarily exclude it. Salman is suspected." Ma Jingbo said.

Han Bin picked up the communication record list and took a look, walked to the projector, and projected the list onto the screen.

"This is the list of David's calls in recent days. David's last call before his death was at 10:27 in the evening. He called a person called Cheng Haibin. The call time was one minute and nineteen seconds. The second call was at 8:52 in the evening, and a person named Cheng Lu called her. The talk time was eight minutes."

"According to the information provided by Qindao Foreign Languages ​​Institute, Cheng Lu is the female classmate who was pregnant by David, and Cheng Haibin is Cheng Lu's father."

Ma Jingbo thought for a moment, "The time of the last call is very delicate. Can you determine when David jumped off the building?"

"Elizabeth, Salman, and Zelay all just said they heard a loud noise after ten o'clock, but they don't know the exact time." Han Bin said.

"In this way, after the suspicion of Salman is eliminated, you can confirm with the three of them the specific time when David jumped off the building."

"I know."

Li Qin continued, "Should you summon Cheng Haibin and Cheng Lu's father and daughter to the police station for transcripts."

Ma Jingbo nodded, "They have the motive of committing the crime and are the last contact of the deceased. Let's apply for the summons procedure."

"Yes."

...

After half an hour, Cheng Haibin and Cheng Lu rushed to the Municipal Public Security Bureau.

Han Bin didn't expect them to come so soon.

Cheng Lu is a girl of about 20 years old. She is not very beautiful. She is tall, with dark skin and slightly raised abdomen. The girl cried as soon as she entered the office, looking very sad.

Cheng Haibin asked as soon as he entered the door, "Comrade police, what is going on? Didn't David be fine yesterday? Why did he suddenly die."

"Listening to you, I seem to care about him a lot." Han Bin said.

Cheng Haibin shouted, "Of course, he is my prospective son-in-law and the father of my grandson. He has an accident, so why not worry."

Han Bin looked at the father and daughter, "Sister Li, take Cheng Lu to the lounge first, let her calm down, and I will make a note for Mr. Cheng first."

Cheng Lu raised her head fiercely, "I'm not going to the meeting room, I want to know how David died."

"Jiang Yang, first bring Cheng Haibin to the meeting room."

"Yes."

After Cheng Haibin left, Huang Qianqian poured a glass of water for Cheng Lu and gave her a few tissues.

Han Bin observed for a while and saw that Cheng Lu's expression did not look like a fake, "Miss Cheng, what is your relationship with David?"

Cheng Lu's voice choked, "Woo... David is my fiancé, the father of the child in my stomach. We will get married soon, who knows he suddenly..."

Han Bin frowned, "When did David say he would marry you?"

Cheng Lu wiped her tears with a tissue, "He asked me to marry me when we had dinner together at noon yesterday. He also said that he would buy me a big diamond ring and take me to get married in America. Our children will also be born in America. , Our children will be Americans in the future."

"But as far as I know, David shouldn't want to get married." Han Bin said.

"That was before, everyone's thoughts had to undergo a process of transformation. He did not want to get married when he first heard that I had children, but then it was different and his thoughts slowly changed." Cheng Lu said.

"Then his change is too fast."

Cheng Lu stared at Han Bin, "What the **** do you mean, are you doubting David's feelings for me?"

Han Bin replied, "When was the last time you contacted David yesterday?"

Cheng Lu recalled, "It was more than eight o'clock last night, less than nine o'clock, we talked for a while, I was a little tired, so I went to bed."

"Is there a connection between your father and David?"

"No, my father doesn't speak English, so he can't communicate directly with David."

"Does your father know David?"

"understanding."

"Did he beat David before?"

Cheng Lu was stunned for a moment, and reacted, "What do you mean?"

"Last night, David called your father, did you know?"

"Impossible, why haven't I heard my father talk about it."

Han Bin wrote a note in the notebook and continued to ask, "Where do you live with your father?"

"We are all staying at Qian Da Hotel, but in different rooms."

"Last night, did your father leave the hotel?"

"Should not, I didn't hear him mention it."

"The hotel has monitoring records. You better not lie."

Cheng Lu stood up fiercely, "What I said is true, my God, you don't suspect that my father killed David, how is this possible? He has no reason to do so."

Han Bin waved his hand and motioned to the other party to sit down, "Don't get excited, we are just asking routinely. This is true for everyone involved in the case."

"Comrade police, please believe me. My father is a good man. Even if he doesn't like David, he will not kill his daughter's husband or his grandson's father. He will never do so." Cheng Lu said with a firm tone.

"Do you have any doubts about the murderer who killed David?" Han Bin asked.

"I..." Cheng Lu pinched her forehead, thinking for a moment, "Yes, David's ex-girlfriend, she must have done it. She knew that David was going to marry me, so she killed David with jealousy. "

"You mean Ma Jiajia?" Han Bin asked.

"It's not Ma Jiajia. David and Ma Jiajia broke up a long time ago. When David chased me, he had a current girlfriend."

Li Qin curled his lips insignificantly.

Han Bin smiled, "What is the name of David's current girlfriend?"

Cheng Lu shook her head, "David is not stupid, how could he tell me."

"Then when did David break up with his current girlfriend?"

"The formal breakup should have been yesterday," Cheng Lu said, and corrected again, "By the way, she is an ex-girlfriend, and I am David's current girlfriend."

"Is it interesting to fight this now?"

Cheng Lu blinked and shouted, "It must be because she couldn't accept the breakup, so she killed David."

This is the first time Han Bin has seen such a righteous young man.

After finishing the transcript, Li Qin took her away.

Afterwards, Jiang Yang took Cheng Haibin back to the office.

"Please sit down, Mr. Cheng."

"Comrade police, how did David die?"

"Falled down from the stairs and died."

"Is it suicide or homicide?"

"From the existing evidence, it should be homicide." Han Bin said.

"Hey, what is this? How will my daughter live in the future." Cheng Haibin patted his forehead vigorously.

"Mr. Cheng, is there a private connection between you and David?"

"No."

"Did he call you last night?"

"No."

"Where were you between nine o'clock and eleven thirty last night?"

Cheng Haibin hesitated and said, "I was going to bed, but after receiving a call, I went out to do something."

"Who called you?"

Cheng Haibin hesitated for a while, and sighed, "Now there is nothing to hide. People from Qindao Foreign Language Institute called me and asked me to go to the school to get some things, saying that it was a little bit of the school's care."

"Why don't you go during the day?"

"How to put it, my daughter is not a glorious thing. The school does not want too many people to know. After all, there are many people in the daytime. The gift-giving person said that it is more convenient at night." Cheng Haibin said .

"What gift did the school give you?"

"There are two bottles of foreign wine, two bottles of red wine, two Chinese cigarettes, and a belt."

"Where is the gift?"

"Still at the hotel."

"You have always been in contact with Kotoshima Foreign Language Institute?"

"Of course."

Cheng Haibin showed a wry smile, "I'm not afraid of your jokes. If it weren't for me to find a school, it would be impossible for the foreigner to agree to marry Lulu. Who would have thought that something happened so soon."

Han Bin guessed, "The Qindao Foreign Language Institute is putting pressure on him in the matter of David marrying Cheng Lu?"

"Yes, Qindao Foreign Languages ​​Institute does not want this to be a big issue, so I am a rat; David does not want to lose his job at Qindao Foreign Languages ​​Institute. And Lulu wants to marry David again." Cheng Haibin said.

Han Bin subconsciously said, "So Qindao Foreign Language Institute came forward to make peace and asked David to marry Cheng Lu, so that David would not have to lose his job and the matter would be resolved."

"Yes, David is a foreign teacher, not a formal establishment, and marrying a student will not affect the Qindao Foreign Language Institute, and it can be regarded as a response to the above political ce." Cheng Haibin finished with a sigh.

"Comrade police, don't you doubt me? To tell you the truth, I really don't like David, but for the sake of my daughter, I still admit it."

"Do you know that the person who called you last night used David's cell phone?" Han Bin asked back.

Cheng Haibin grew his mouth wide, "How is this possible... I never saw David last night. Someone must have framed me."

"How do you prove that you went to school to get things instead of seeing David?" Han Bin asked back.

Cheng Haibin was anxious, "The gift is still in the hotel. If you don't believe me, please check it. Besides, I don't understand English. He called me and I don't understand it either."

"We will check."

"Sure enough, it's right that I don't like this red-haired ghost. This **** died on his own, and it hurts me." Cheng Haibin gritted his teeth, then his expression changed, as if he was thinking of something.

"By the way, I have a recording. I recorded yesterday's mobile phone conversation."

Han Bin was a little surprised, "Why do you want to record?"

“It’s not easy for me to seek justice for my daughter alone, and I’m more concerned about dealing with the school. As long as I communicate with the school, regardless of whether it’s face-to-face or cell phone calls, I will secretly record it. If you don’t believe me, you can listen to it. I definitely didn’t lie. "Cheng Haibin took out his cell phone and played a recording of the conversation.

"Hey, is this Mr. Cheng? I'm from Qindao Foreign Language Institute..."
