Han Bin listened to it twice in a row, and indeed someone claimed to be a teacher at Qindao Foreign Language College and asked Cheng Haibin to go to the school to get a gift.

The caller was deliberately hiding his true voice.

But I can still hear that the other party should be a female surname.

"Mr. Cheng, do you have any impression of this person's voice?" asked Han Bin.

"It's weird, it's not impressive. ”

"What does the person who gave you the gift look like?"

Cheng Haibin recalled, "I didn't see it clearly, I walked near the teaching building, she waved at me, then put down her things and left, but she looked like a woman." ”

"The other person beckons to you, probably recognizing you, maybe you've seen her too, and you remember carefully her features, clothes, and shoes at that time. ”

"She's a bit chubby, wears a black coat, and I can't remember what shoes she was wearing. ”

"What's the room number you live in?"

"Room 703 of the Chida Hotel. ”

"According to the regulations, we have to take your DNA and fingerprints, and your mobile phone must also be temporarily handed over to the police as evidence. ”

Cheng Haibin could only nod helplessly.

After Cheng Haibin left, the group held a summary meeting of the case again.

Cheng Haibin's situation is similar to that of Salman, and it is very likely that he was framed, but this is only his one-sided statement, and his suspicion of committing the crime cannot be ruled out.

Subsequently, Ma Jingbo seconded two team members from the second group to Qindao Foreign Language Institute to investigate.

Li Qin and Jiang Yang went to the Qianda Hotel to investigate.

Huang Qianqian sent Cheng Haibin's mobile phone to the technical department for testing.

Han Bin was not idle, he came to the gate of the Municipal Public Security Bureau to greet Haruk.

Haruch doesn't speak Chinese, and only Han Bin can communicate with him.

Haruk is in his Chinese New Year's Eve, with a big beard, deep facial features, wheat complexion, and a little like Zeraj between his eyebrows, but much more handsome than Sharman.

After returning to the office, Huang Qianqian also happened to come back, just to assist Han Bin to make a transcript for Haluk, to put it bluntly, it was a humanoid video recorder.

Han Bin made a gesture of please, "Mr. Haruk, please take a seat." ”

"Thank you. ”

"Mr. Haloch, thank you for your assistance in our police investigation. Han Bin said politely.

Haloch spread his hands, "No way, who let me have a stupid sister." ”

"Sounds like you're a little unhappy with Zerai?"

"No, my sister is good, I love her, but I don't like her boyfriend. ”

"Sharman?"

"yes, that's the guy, you've seen him. ”

"Of course. ”

Haloch scoffed, "Do you think he can be worthy of Zeraj?"

Han Bin smiled, he couldn't take it.

"yes, I'd rather her marry a foreigner than Sharman. ”

"Yesterday, you were a guest at Zerai's house?"

"Yes, the dormitory building of the foreign teachers of the Qindao Foreign Language Institute. ”

"What time did you go?"

"It seems to be five o'clock, Kotoshima is good at everything, but the curry is too inauthentic. ”

"What time did you leave?"

"I think it's around 9 o'clock. ”

Han Bin made a note in his notebook, "Did you drink that night?"

"I don't drink, but Salman does, oh, this guy knows I'm religious, and he still drinks in front of me, and that's why I don't like him. ”

"What kind of wine does Sharman drink?"

"Beer, and drank two cans. ”

Haluk's confession is consistent with Sharman and Zeraj, and the confessions of the three corroborate each other, and Zeraj's testimony is also more probative.

Huang Qianqian invited Zeraj and Sharman over, and Han Bin had another question he wanted to ask the two.

Han Bin invited the two of them to sit down and said with a smile, "Thanks to the cooperation of the two of you, we have ruled out Mr. Sharman's suspicion." ”

Sharman breathed a sigh of relief, "Karma, thank you, Officer Han, and Haruk." ”

Zeraj clasped his hands together, "Officer Han, thank you so much. ”

Han Bin changed his words, "I have one more question that I want to ask the two of you." ”

"What's the problem?"

"Who is David's girlfriend?"

Zeraj's face changed slightly, and he glanced at Sharman next to him.

Sharman took a deep breath, "Does this case matter?"

Han Bin nodded, "Of course." ”

Sharman hesitated, "Actually, we don't know David very well, and we haven't asked this kind of personal question......

Han Bin stretched out his hand to interrupt Shalman's words, "Isn't it Chen Haijing?"

Zeraj and Sharman looked at each other again.

Subsequently, Zelai said slowly, "Actually, we don't know this matter very well, and we haven't asked David, let alone dare to ask Chen Haijing for verification, but with a woman's intuition, I feel that the relationship between the two is not ordinary." ”

"Officer Han, in fact, we didn't mean to hide it, but Chen Haijing is our leader after all, and we don't want to offend her. Zeraj sighed.

"OK, I understand. Han Bin got up and shook hands with the two, "Thank you for your cooperation." ”

"It should. Zeraj looked sincere, "Thank you again for giving Sharman a clean slate." ”

After seeing the three of them leave, Han Bin fell into deep thought.

Shalman's suspicion has been ruled out, so there are two more suspects, one is Cheng Haibin, and the other is David's girlfriend.

Based on Han Bin's speculation, Chen Haijing is likely to be David's girlfriend.

David's mysterious girlfriend has never appeared publicly, and Han Bin has also checked David's call records and has not found a contact person suspected of his girlfriend, but David and Chen Haijing have always been in contact.

Because of the working relationship between the two, no one doubted it at first, but now it seems that the relationship between the two is not ordinary.

Zelayi's words are equivalent to confirming Han Bin's guess.

If Chen Haijing is really David's girlfriend, then she will be very suspicious.

If David really proposed to Chen Haijing to break up, Chen Haijing would have a motive to kill.

Chen Haijing is familiar with the situation of the foreign teaching building, and also knows about the transaction between Cheng Haibin and the Foreign Language College, and she is likely to be the person who called Cheng Haibin.

Of course, this is just Han Bin's speculation, and everything depends on the evidence.

In fact, the reason why Han Bin guessed that Chen Haijing was David's girlfriend was through reverse extrapolation.

Assuming that what Cheng Lu said is true, David really has a girlfriend, then this girlfriend has a motive to commit the crime.

And if it was really David's girlfriend who did it, it was not enough to have a motive, but also to be familiar with the situation of the foreign teacher's dormitory, know the transaction between Cheng Haibin and the college, and even have Cheng Haibin's contact information.

If you push it back in this way, Chen Haijing is the most qualified person, and she is also the person who knows the case best besides the police.

Of course, speculation cannot be conclusive, and evidence is needed to prove it.

Han Bin thought for a while, then took out his mobile phone and dialed Chen Haijing's number.

"Hey, is it Director Chen?" Han Bin pressed the call recording button.

"It's me, Officer Han, what's the matter with you?"

"Have you communicated with the school leaders about the monitoring of the foreign teacher's dormitory building?"

"Yes, the school leadership decided to reinstall the monitors. ”

"One thing I would like to remind you is that the house that David used was not allowed to be entered by anyone without the permission of the police. ”

"I see. Chen Hai responded quietly and said with concern, "Is there any progress in David's case?"

"The investigation is still ongoing, and the school will be informed of the exact results. After Han Bin finished speaking, he hung up the phone.

"Qianqian, come over here. ”

Huang Qianqian walked over, "Team leader, what's the matter with you?"

"I'll send you a call recording, and you can compare it with Cheng Haibin's call recording to see if it's the same person's voice. ”

"Okay. ”

Although the person who called Cheng Haibin deliberately disguised his voice, which made it difficult for people to distinguish for a while, it was still possible to identify whether it was the same person's voice through professional instrument detection.

If the voice comparison is successful, then Chen Haijing's suspicion will rise further.
