At six o'clock in the afternoon, everyone returned to the office one after another.

Han Bin personally poured a cup of tea for Ma Jingbo and said with a smile, "The horse team has worked hard. ”

"Count on you, kid, and still have a little conscience. Ma Jingbo took the teacup and blew on the floating leaves.

"Did you find anything on this trip?"

Ma Jingbo nodded, "Gather everyone together and have a meeting." ”

"Yes. ”

Ma Jingbo glanced at everyone, a group of people had arrived, and his gaze fell on Wang Xiao and Bao Xing, "How are you two checking, have you found that white Hyundai car?"

"We went to Yubin Road and Nanhuai Street near the investigation, the location there is relatively remote, in addition to the main road has surveillance, there is no Skynet monitoring on the auxiliary road, we have collected some private monitoring of the nearby auxiliary road, at present, has not found the whereabouts of the white modern car. Wang Xiao said.

"This clue can't be put down, and we have to continue to investigate. ”

"Yes. ”

"Li Qin, what did you find over there?"

"Jiang Yang and I went to the Qianda Hotel, checked the hotel's surveillance, and Cheng Haibin left the hotel at about 10:30. We found two bottles of foreign wine, two bottles of red wine, two Chinese cigarettes, and a belt in his hotel room. ”

Li Qin said and took out a report, "After that, we took these items to the technical department, and after comparison, in addition to Cheng Haibin's fingerprints, there were also the fingerprints of the deceased David. ”

Ma Jingbo took over the conversation, "I went to Qindao Foreign Language Institute to check the surveillance, Cheng Haibin did go to the academy last night, and it was 10:51 when he arrived at the gate of the academy, and he was empty-handed at that time. It was eleven and three o'clock when I left the academy, and I was carrying something in my hand. ”

"Although there is also monitoring within the college, the monitoring and control are not comprehensive, and it is impossible to photograph all the movements of Cheng Haibin. ”

Judging from the current clues, it is very likely that Cheng Haibin was wronged. Han Bin said.

"How do you explain that the gift has David's fingerprints on it?" asked Li Qin.

Han Bin thought for a moment, "I guess it's likely that the murderer killed David and took something from David's house and gave it to Cheng Haibin." ”

Bao Xing said with a smile, "David, a foreign devil, also likes to smoke China." ”

Han Bin shook his head, "I don't think I bought it, but it looks like someone else gave it to him." ”

Bao Xing asked, "This gift is not light, who would give a gift to a foreigner?"

Han Bin said, "Qindao Foreign Language College." ”

Bao Xing smashed his mouth, "Tsk, the treatment of this foreign teacher is too good, and he actually sends foreign wine and Chinese cigarettes." ”

Wang Xiao smiled, "This is called a foreign monk to chant the scriptures." ”

Li Qin brought the topic back again, "I think Cheng Haibin himself is also suspicious, if it is really him who killed David, snatched the gift from David's family, and blamed Sharman at the same time, can it be explained?"

"What about motivation?"

Li Qin replied, "David himself did not want to get married, and the reason why he reluctantly agreed was because of the pressure from the school. Cheng Lu and David also spoke on the phone that night, if David told Cheng Lu that he didn't want to get married, Cheng Haibin would be able to spare him?"

Han Bin asked rhetorically, "How do you explain that call recording?"

Li Qin replied, "Could it be that after he killed David, he asked people to use David's mobile phone to make calls, deliberately trying to interfere with the police investigation." ”

Han Bin shook his head, "Cheng Haibin only had a total of twelve minutes from entering the school to leaving the school, which was not enough time for him to kill people, frame Sharman, and then find a woman to use David's mobile phone to pretend to call, and finally, leave calmly with David's things." ”

Ma Jingbo nodded, "Yes, I agree with Han Bin's analysis, the area of Qindao Foreign Language Institute is not small, and some places are monitored, judging from the existing surveillance video, Cheng Haibin cannot complete the act of killing and planting bribes within twelve minutes." ”

Ma Jingbo tapped his finger on the table, "The key clue now is who used David's mobile phone to call Cheng Haibin, and that person is likely to be the real murderer." ”

Han Bin organized the language, "I have some speculation about the identity of this person, this person is familiar with the situation of the foreign teaching building, the relationship between Cheng Haibin and the school, and he also has the motive to commit the crime. ”

Everyone looked over, "Who?"

Han Bin didn't go around the bend and got straight to the point, "Chen Haijing, she meets all the conditions of the suspect." ”

Li Qin asked, "What about the motive for the killing?"

Han Bin explained, "Cheng Lu said that David has a girlfriend, but we have been in contact with David for so long and have never seen David's mysterious girlfriend, which shows that the two are a little disgraceful, according to my speculation, Chen Haijing is likely to be David's girlfriend, and this speculation has also been confirmed from Zelay." ”

"It's a day, it's hidden deep enough, these two people are actually together. Bao Xing showed a surprised look and said curiously, "Chen Haijing is not beautiful, she is average, and she is old, why did David fall in love with her." ”

Although Chen Haijing looks average, she is the deputy director of the English department, and she is directly responsible for the recruitment and management of foreign teachers, in other words, she has a way to make David, a foreign monk, unable to read scriptures. Han Bin said with a smile.

Ma Jingbo added a cup of tea, "Your analysis makes some sense, is there any evidence?"

"I made a phone call to Chen Haijing, recorded the call, and sent Qianqian to the technical department for comparison, and I believe that the results will be available soon. Han Bin said.

"Good job. Ma Jingbo praised it, and the words changed, "Is there any progress in Howl's interrogation?"

"Not yet. ”

Ma Jingbo said, "Qindao Foreign Language Institute came forward to handle the formalities for Hal's release on bail pending trial. ”

Han Bin frowned, "Why?"

Ma Jingbo shrugged his shoulders, "The leader of the academy said that this is a request from Mike's family. ”

"This Qindao Foreign Language Institute is too cowardly. Bao Xing snorted.

Wang Xiao pursed his lips, "It's still the same sentence, foreign monks are good at chanting, and Qindao Foreign Language College is nothing more than the idea of calming people." ”

Ma Jingbo waved his hand, "Don't complain, focus on investigating the case, as long as you can find ironclad evidence of Howl's murder, he can't run." ”

Ma Jingbo glanced at his watch, got up and said, "It's not early, let's go to dinner first, I'll go to the technical department to have a look." ”

Ma Jingbo walked to the door, and as soon as he opened the office door, he found that someone was walking towards the door, it was Chen Yan from the technical department.

"Yo, where are you going, Captain Ma?" asked Chen Yan.

"I'm getting ready to go for a walk around the technical department. ”

Chen Yan smiled and shook the information in his hand, "No need to go, I brought the test results." ”

"How?"

"We did a voiceprint identification of the two call recordings, compared and analyzed the frequency, waveform, and sound intensity, and found that the woman's voice in the two recordings came from the same person. ”

"Well, that's a great piece of evidence. Ma Jingbo said with a smile.

With the appraisal of the technical department, Han Bin's speculation has evidence and confirms Chen Haijing's suspicion.

Ma Jingbo instructed, "Qianqian, go and apply for a detention warrant and a search warrant, and the others are ready to act!"

......

Kotoshima Institute of Foreign Languages.

Chen Haijing walked to the school gate with a black satchel on her back, her expression looking a little haggard.

Chen Haijing walked to the gate of the academy, stood for a moment, and then turned his head and walked back.

However, after walking a few steps, I thought about walking outside the academy again.

After leaving the academy, I walked a few dozen meters to the east and stood on the side of the road waiting for the bus.

Chen Haijing looked a little absent-minded, and sighed from time to time.

"Woo ......"

The two cars stopped on the side of the road, and several people got out of the cars, who were from the Second Squadron of the Municipal Criminal Investigation Team.

Chen Haijing was stunned for a moment, and said in surprise, "Captain Ma, Officer Han, why are you here?"

Ma Jingbo looked at the other party, "Director Chen, we would like to ask you to go back to the police station to learn about the situation." ”

Chen Haijing swallowed his saliva and forced a smile, "I have something to do today, can I do it tomorrow?"

Han Bin showed his detention summons, "Director Chen, please cooperate." ”
