Detective from the future

Chapter 480 Comparison
Han Bin listened to it twice in a row. Indeed, someone claimed to be a teacher from Qindao Foreign Language Institute and asked Cheng Haibin to go to the school to pick up gifts.

The caller was using his accent, deliberately concealing his true voice.

However, it can still be heard that the other party should be a female surname.

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

"I don't have any impression of the strange tone."

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

Cheng Haibin recalled, "I didn't see it clearly. When 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 party is waving to you, probably because he recognized you, maybe you have seen her before, please recall carefully her features, clothes, and shoes at that time."

"She was a bit fat, she was wearing a black coat, I can't remember what shoes she was wearing."

"What's the number of your room?"

"Room 703 of Qianda Hotel."

"According to the regulations, we will extract your DNA and fingerprints, and your mobile phone will also be temporarily handed over to the police as evidence for safekeeping."

Cheng Haibin could only nod helplessly.

After Cheng Haibin left, the group held a case summary meeting 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 investigate at Qindao University of Foreign Languages.

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

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

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

Haruk does not speak Chinese, and only Han Bin can communicate with him.

Haruk is in his 30s, with a big beard, deep facial features, and a wheat complexion. His eyebrows and eyes are somewhat similar to Zelay, but he is much more handsome than Salman.

After returning to the office, Huang Qianqian just came back to assist Han Bin to take notes for Haruk. To put it bluntly, it is a humanoid video recorder.

Han Bin made a gesture of invitation, "Mr. Haruk, please sit down."

"Thank you."

"Mr. Haruk, thank you for assisting our police investigation." Han Bin said politely.

Haruk spread his hands, "I can't help it, who made me have a silly little sister."

"It sounds like you're a little dissatisfied with Zelay?"

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

"Salman?"

"Yes, that guy, you've seen him too."

"of course."

Haruk sneered, "Do you think he is worthy of Zelay?"

Han Bin smiled, it was difficult for him to answer.

"Yeah, I'd rather she marry a foreigner than Salman."

"Yesterday, you went to Zelay's house as a guest?"

"Yes, the foreign teacher's dormitory building of Qindao Foreign Language Institute."

"What time did you go?"

"It seems to be after five o'clock. Qindao is good for everything, but the curry is too unauthentic."

"What time did you leave?"

"It seems to be around 9 o'clock."

Han Bin wrote it down in his notebook, "Did you drink alcohol that night?"

"I don't drink, but Salman drank. Damn, this guy knows I'm religious, but he still drinks in front of me. That's why I don't like him."

"What wine did Salman drink?"

"Beer, and I drank two cans."

Haruk’s statement is consistent with that of Salman and Zelay, and the statements of the three corroborate each other, and the witness of Zelay is also more convincing. After comprehensive consideration, Han Bin feels that Shar can be ruled out for the time being. Man's suspicion.

Huang Qianqian invited Zerai and Salman over, and Han Bin had another question he wanted to ask them.

Han Bin asked the two to sit down and said with a smile, "Thank you for your cooperation, we have ruled out the suspicion of Mr. Salman."

Salman breathed a sigh of relief, "Damn, thank you, Officer Han, and Haruk."

Zerai clasped his hands together, "Officer Han, thank you very much."

Han Bin changed the subject, "I have another question, I want to ask you two."

"what is the problem?"

"Who is David's girlfriend?"

Zelay's face changed slightly, and he glanced at Salman next to him.

Salman took a deep breath, "Is this case related?"

Han Bin nodded, "Of course."

Salman hesitated, "Actually, we are not very familiar with David, and we have never asked such personal questions..."

Han Bin reached out and interrupted Salman, "Is it Chen Haijing?"

Zelay and Salman looked at each other again.

Afterwards, Zelay said slowly, "Actually, we are not very clear about this matter, and we have never asked David, and we dare not ask Chen Haijing for confirmation, but with a woman's intuition, I feel that the relationship between them is unusual. "

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

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

"It should." Zelay showed a sincere look, "Thank you again, and returned Salman's innocence."

After watching the three leave, Han Bin fell into deep thought.

The suspicion of Salman was ruled out, so there are two more suspects, one is Cheng Haibin, and the other is David's girlfriend.

According to Han Bin's speculation, Chen Haijing is probably David's girlfriend.

David's mysterious girlfriend has never appeared in public. Han Bin also checked David's call records and found no contact person who is suspected of his girlfriend, but David and Chen Haijing have been in contact.

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

Zerai's words were equivalent to confirming Han Bin's conjecture.

If Chen Haijing was really David's girlfriend, then she would be very suspicious.

If David really broke up with Chen Haijing, Chen Haijing would have the motive to kill.

Chen Haijing is familiar with the foreign teaching building and the deal between Cheng Haibin and the School of Foreign Languages. She is probably the one who called Cheng Haibin.

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

In fact, the reason why Han Bin guessed that Chen Haijing was David's girlfriend was through the means of inversion.

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

And if David's girlfriend really did it, motivation alone is not enough. You also need to be familiar with the foreign teacher's dormitory, know the deal between Cheng Haibin and the college, and even have Cheng Haibin's contact information.

In this way, Chen Haijing is the most qualified person and the person who knows the case best besides the police.

Of course, conjectures cannot be settled, and evidence is needed to prove them.

Han Bin thought for a while, took out his mobile phone and called Chen Haijing.

"Hello, is this Director Chen?" Han Bin pressed the call recording button.

"It's me, Officer Han, what can you do?"

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

"Yes, the school leadership decided to reinstall the surveillance."

"One thing I want to remind is that no one is allowed to enter the house that David has used without the permission of the police."

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

"It's still under investigation, and the school will be notified of the definite results." After Han Bin finished speaking, he hung up the phone.

"Qianqian, come here."

Huang Qianqian came over, "What's the matter, leader?"

"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."

"Ok."

Although the person who called Cheng Haibin intentionally disguised his voice, making it difficult for people to distinguish for a while, but it can still be detected by professional equipment to identify whether it is the same person's voice.

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