Police station.


    Because the flat panel has limited power and can''t be charged, it can''t keep the screen on all the time. It can only watch the video for 10 minutes every other hour, trying to find some clues to determine the location of the crime.


    This task was given to Chiba, and Sato was assigned to another room to record confessions for Bumei, so as to facilitate the profile of criminals.


    It can be seen that Takagi''s accident had a great impact on Sato. Even when he left, Sato watched the video for a long time in silence.


    Gao Chengji stood aside and did not interfere in the work arrangement of the police department.


    At present, the investigation direction of the police department is not wrong. White bird even went to Gaomu residence for investigation, and I believe that a lot of information will be collected soon.


    The problem is


    Gao Cheng always thinks about tablet video in his mind.


    There are several doubtful points. First, why should the prisoner arrange the transmission of pictures from three angles in turn? If only one or two angles are enough to make people understand Takagi''s situation, then why should the prisoner specially give it to officer Sato.


    Most people don''t know the relationship between Takagi and Sato.


    Finally, there is a faint sense of disharmony in the video, and there is a piece of tarpaulin in the middle of the board with high wood. It''s not strange at the construction site, but it''s not right to put it on the board with high wood.


    That''s it. At first glance, it''s nothing. In fact, there are some noteworthy details.


    If the prisoner wants to cover the camera, there should be something hidden under the board. Even the bomb is no surprise.


    Who would hate the good guy so much? Or is it officer Sato who really hates?


    "Well," Sato continued, after getting the prisoner''s portrait from bumiki''s description, "so, what did you notice about this man''s habitual actions and tone of speech?"


    "It seems that there is nothing special..."


    "No, no! Officer Sato! " Chiba suddenly burst into the door, "Gaomu, something happened to him!"


    "What?"


    When searching the office of Yike, the camera is facing the flat panel and recording. At this time, Takagi doesn''t know why. The whole person turns over and falls out of the board.


    "What''s the situation?" Sato sweating, "why is he about to fall?"


    "I, I don''t know," Chiba turned pale. "When I was going to record the third video of today, it suddenly became like this..."


    The policemen in the crowd shook their heads and said, "it''s been such a long time. It''s not surprising even if they abandon themselves. Maybe Gao Mu is..."


    "It''s OK," Gao Cheng interrupted the crowd and said to the frightened Sato, "if it''s self abandonment, it will have fallen down. Now officer Takagi is still keeping his balance, so he should have his own plan."


    "It''s the police manual," Conan reminded, pointing pointedly at the black part of Takagi''s shoulder. "He wants to pour out the police manual in his arms. If anyone finds it, he can know the location."


    "Yes, is that so?"


    Sato looked at shaking out the police manual after slowly retracting the upper half of the body lying on the board gasping high wood, finally relieved.


    Anyway, as long as Takagi remains calm, there is still hope.


    It''s getting late. Even though the criminals have been mobilized, they still don''t find any clues. No clues have been found in Gao Mu''s residence, and no suspicious places have been found in the cases related to Gao mu. However, by chance, a police officer took the initiative to mention that when he saw Gao Mu coming out of the reference room last week, Gao Mu was still in tears.


    On this point, Takagi seems to have shed tears on the day of his disappearance. The Management Officer immediately issued new instructions to find the information that Takagi consulted.


    Although Gao Cheng is not the main force of the investigation, as a special consultant of the search lesson, he also got the information.


    What Takagi looked up was the data of women who hanged themselves a year ago. Sato and Takagi had gone to the scene to look at the three cases together, because they were only suicides, so they could judge whether they were criminal cases and let the police station in the jurisdiction close the case.


    The first case was a sixth year student in the Department of medicine of Dongdu University, named tomuko.


    "Yes," Sato explained, "she hanged herself in the living room of her apartment. Although it doesn''t look like a girl''s room, it''s also very clean. According to the suicide note under her feet, she ran away in her own car a few days ago, and then she can''t bear the condemnation of her conscience."


    "The second person is a lecturer in the English conversation school in Tokyo. Her mother is an American, Miss Natalie Lai Jian. According to the calendar on her wall, she dates her boyfriend almost every day. As a result, she was abandoned by her boyfriend and felt desperate. On the day of her suicide, she would have dated her boyfriend."


    Sato recalled: "although there was no suicide note, the mobile search team who first arrived at the scene said that there was an English email sent to the American mother in her mobile phone."


    "Then there is the third person, who is the most popular waitress in liubenmu bar. Yan went to Jinghua. Although she seems to have made a lot of money, she lives in an old apartment with empty beer cans in the room. According to her diary, she gave all the money to her boyfriend. As a result, she found that the man was a marriage swindler. After he was frustrated, he hanged himself."


    Sato held his arm and thought, "the reason why I found out is that the man borrowed a lot of money. Because of usury, he had a conflict with others and killed them. After being arrested by police officer IDA, he got on the news and was seen by Yan shangjinghua."“ Officer IDA? " Gao Cheng was stunned. It seems to have some impression“ By the way, none of you have seen it, "Sato said regretfully." it''s the IDA air police officer who used to take Takagi. Unfortunately, he died in a traffic accident soon after catching the liar... "Takagi said that he wanted to pick up the police manual that fell on the ground, but he was hit by a tired car. It happened that the two of them had been monitoring all night, On the way back after daybreak... "The black police manual that Takagi has been using is the last relic given to him by officer IDA. It seems that he wants to fill up the police manual and become a policeman like officer IDA." Gao Cheng quietly listens to Sato''s story and gradually thinks of the identity of IDA airlines. It''s like an Shitou''s classmate in the police school, but he has already died early, which is similar to matsutada''s flat. Gao Cheng sighed and thought back to the case. It''s another bullshit situation, but it''s one of them that really matters. Think about it from Takagi''s point of view, why do you suddenly check the information of these three women who committed suicide, why do you shed tears, and finally go to meet someone without telling Sato. The first medical student''s hometown is in Gaozhi County of Shikoku, but his family moved away half a year ago, and there is no new address yet. The second is Natalie, an English teacher. She was born in Hokkaido. Her only relatives are her parents. However, a year ago, when she came to claim her daughter''s body, she encountered a traffic accident and both died. The third hostess, Yan shangjinghua, lied about her birthplace at the place where she worked, so her identity has not yet been identified. However, according to colleagues, she seems to be from Kyushu Boduo. Gao Cheng frowned. Shikoku, Hokkaido and Kyushu all need to stay for a night. That is to say, all three places may be Takagi''s destinations. Moreover, the distortion of the reported clue information is inevitable, even if Sato reported it. The key is what Takagi found a year later, so that he suddenly checked the information and went to meet someone strangely yesterday. The first medical student committed suicide because of hit and run, which seems to have nothing to do with Takagi. Even if he didn''t commit suicide, there''s no need to deal with it in private. The second English teacher was abandoned by her boyfriend and committed suicide, which seems to have nothing to do with Takagi. The third one is the hostess. Because she met the cheater''s boyfriend, she was disheartened and committed suicide. It had nothing to do with Takagi. Although she was a police officer at the scene, she should consult Sato first even if she found that she didn''t commit suicide. If there''s any connection, officer IDA with Takagi arrested the liar. Gao Cheng suddenly stops in the corridor and raises his head. If it had nothing to do with Takagi, from other perspectives, the common points of the three people were "suicide" and "women", and then they were all a year ago. The only thing that can make Gao Mu associate with these things is... Gao Cheng''s mind comes up with the police manual on Gao mu. By the way, it''s IDA.
