Chapter 480

Han Bin listened to it twice in a row. Someone claimed to be a teacher of Qindao foreign language college and asked Cheng Haibin to go to school to get a gift.

The caller kept his voice to himself.

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

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

"I'm not impressed by the strange tune."

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

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

"When you wave in the opposite direction, you probably recognize you. Maybe you've met her. You can recall her characteristics, clothes and shoes at that time."

"She's a little fat. She's wearing a black coat. I can't remember what shoes she's wearing."

"What's your room number?"

"Qianda hotel room 703."

"According to the regulations, we need to extract your DNA and fingerprints, and your mobile phone should be taken as evidence and temporarily handed over to the police."

Cheng Haibin can only nod helplessly.

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

Cheng Haibin's situation is similar to Shalman's, and it is likely that he was planted, but this is only one side of his story, and he can't be ruled out.

Later, Ma Jingbo seconded two team members from group two to Qindao foreign language college for investigation.

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

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

Han Bin is not idle, he came to the City Public Security Bureau to meet haruke.

Haruke can't speak Chinese, and only Hanbin can communicate with him.

Haruke is in his thirties. He has a big beard, deep features, wheat complexion and looks a bit like Zelai. He is much more handsome than Salman.

After returning to the office, Huang Qianqian just came back to help Han Bin take notes for haruke. To put it bluntly, it's a humanoid video recorder.

Han Bin made a please sign, "Mr. haruke, please sit down."

"Thank you."

"Thank you, Mr. haruk, for assisting us in the police investigation." Han Bin said politely.

Haruke spread his hand, "no way, who let me have a silly sister."

"Sounds like you're not happy with Zelai?"

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

"Salman?"

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

"Of course."

Haruk sneered. "Do you think he's worthy of Zelai?"

Han Bin smiles, which is hard for him to answer.

"Yeah, I'd rather she married a foreigner than Shalman."

"Yesterday, you went to Zelai's house?"

"Yes, the dormitory building of Qindao foreign language college."

"What time did you go?"

"It seems to be more than five o'clock. Qindao is good for everything, but curry is too unorthodox."

"What time did you leave?"

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

Han Bin wrote in his notebook, "did you drink that night?"

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

"What's Salman drinking?"

"Beer, two more cans."

Haruke's confession is consistent with Salman's and Zelai's, and the confession of the three should testify to each other. Zelai's witness is also more powerful. After a comprehensive consideration, Han Bin thinks that Salman's suspicion can be ruled out for the time being.

Huang Qianqian will Zelai and Shalman invited over, Hanbin also has a question to ask two people.

Han Bin asked them to sit down and said with a smile, "thank you for your cooperation. We have ruled out Mr. Salman's suspicion."

Salman breathed a sigh of relief, "well, thank you, officer Han, and haruke."

Zelai put his hands together. "Officer Han, thank you very much."

Han Bin's words changed, "I have another question. I want to ask you two."

"What's the problem?"

"Who's David's girlfriend?"

Zelai's face changed slightly, and he took a look at Salman beside him.

Salman took a deep breath. "Does this case matter?"

Han Bin nodded, "of course."

Salman hesitated. "In fact, we don't know David very well. We haven't asked this kind of personal question..."

Han Bin stretched out his hand to interrupt Salman's words, "is it Chen Haijing?"

Zelai and Salman look at each other again.Later, Zelai said slowly, "in fact, we are not very clear about this matter, we have not asked David, and we dare not ask Chen Haijing to prove it. But with a woman's intuition, we feel that their relationship is unusual."

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

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

"It should be." Zelai showed a sincere look, "thank you again, but also a clear Salman."

After seeing the three leave, Han Bin is lost in meditation.

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

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

David's mysterious girlfriend has never appeared in public, and Han Bin has checked David's call records, and has not found any contact with his suspected girlfriend, but David and Chen Haijing have been in contact.

At first, no one doubted their working relationship, but now it seems that their relationship is not general.

Zelai's words are tantamount to proving Hanbin's conjecture.

If Chen Haijing is really David's girlfriend, then her suspicion will be very big.

If David does break up with Chen Haijing, Chen Haijing will have a motive to kill.

Chen Haijing is familiar with the situation of the foreign teachers' building, and knows about the transaction between Cheng Haibin and the Foreign Language Institute. She is probably the person who called Cheng Haibin.

Of course, this is only Han Bin's conjecture, everything depends on the evidence.

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

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

If it's really David's girlfriend who did it, it's not enough just to have motivation. He should be familiar with the dormitory building of foreign teachers, know the transaction between Cheng Haibin and the college, and even have Cheng Haibin's contact information.

If pushed back in this way, Chen Haijing is the most qualified person and the one who knows the case most besides the police.

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

Han Bin thinks for a while, takes out his mobile phone and dials Chen Haijing.

"Hello, is that director Chen?" Han Bin pressed the call recording key.

"It's me, officer Han. What can I do for you?"

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

"Yes, the school leaders decided to re install the monitoring system."

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

"I see." Chen Haijing answered and said, "is there any progress in David's case?"

"It's still under investigation, and the school will be informed of the exact results." Han Bin finished, hang up the phone.

"Qianqian, come here."

Huang Qianqian came over and said, "what can I do for you, group leader?"

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

"All right."

Although the person who called Cheng Haibin deliberately disguised his voice, which made it difficult for people to distinguish at one time, it can still be detected by professional instruments to identify whether it is the same person's voice.

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