Chapter 136: The first problem Baijin City Public Security Bureau, front office. Not long after Su Chen left. Deputy Director Lu Ping pushed open the door with several special police officers and walked in in a hurry. After working hard in the middle of the night, several people had tired faces. "The little girl's condition is okay. She will be discharged from the hospital after one night of observation. With Officer Bai accompanying her at the hospital, there won't be any problems." "Officer Qin and the others have just loaded the body into the truck. It will probably be transported to the police station in a while. Yes, our autopsy room is ready..." "Officer Wang Yanxing, I asked him to write the progress report on the Platinum Case. He is an expert in trace detection and is more careful. He will write better than our police officers." Lu Ping turned to the phone and made a report. On the other side of the phone, an old voice came over, a little hoarse, he must have just smoked a lot. "Very good, Xiao Lu. When it comes to a big case, you can do things very quickly. You are a leader. I am getting older... What a coincidence. When the Platinum Case was restarted, Su Chen happened to lead a group of people. The help experts came to Baijin City is like a magic weapon coming from heaven. "
"In the past, in a small place like Platinum City, it was impossible to gather so many people at the same time. The opportunity was rare." "Yes, Director Zhang, I have to find out something no matter what I do this time. I can't be empty-handed again..." Deputy Director Lu Ping nodded and agreed. Then, a hint of doubt suddenly appeared on his face, he lowered his voice and whispered into the microphone: "Director Zhang, you were so anxious to ask me for the latest progress information on the Platinum Case... is there any use for it? New experts have been sent from above?" As soon as he said this, there was silence on the other end of the phone for two seconds. "Ahem..." The old director cleared his throat and said thoughtfully: "It's not the experts above who want it. I'm just passing it on and passing it on." "It's the representative of the World Detective Association in Dragon Kingdom. He asked me for this information, and it's urgent... He said it was needed by a member of the World Detective Association, and this member is not low-level." "World Detective Council?!" Director Lu Ping was stunned for a moment. Although he had heard that members of the World Investigation Council would indeed participate in solving cases around the world, this was the first time he encountered something real. The World Detective Association is very deep, and there are many world-class detectives in it. If this platinum case really arouses the interest of a certain big shot, then maybe there will be another glimmer of hope in solving the case. Deputy Director Lu Ping half-sighed and half-smiled: "If it weren't for that guy Su Chen causing so many troubles in Platinum City, the Platinum case wouldn't have attracted so much attention... maybe we would really have to thank him now." Speaking of which, that guy has never been seen again since he escaped from the chess academy. Maybe he has fled to another city, or maybe he has gone abroad. I heard that a vote to introduce programs is being held in Sakura Country. It's best this way, Lu Ping thought to himself. The platinum case was already a headache. Without Su Chen, they wouldn't have to devote their energy to dealing with him. Passing by the reception room of the police station, he glanced inside specifically, but did not see the thin, dark old man from before.
Lu Ping couldn't help but feel a little confused. He looked at the female police officer at the front desk and asked: "Where did that elderly family member go? He didn't run away to sleep, right?" The female police officer pointed to the side and said: "I just went to the toilet. Well, it's been almost ten minutes now." "That's good, that's good." Lu Ping nodded with concern and whispered: "He is an old man who has come all the way from afar and has nowhere to go in Platinum City. You can find him a folding bed and let him settle in the bureau for one night. I approve." After thinking for a while, he added: "It just so happens that there are a lot of police officers in the bureau going out to investigate tonight, and they won't be able to come back overnight. Just find a temporary lounge for them to stay. I have too many things to do, so please take care of me." "Okay Lu Bureau." The girl police officer who had just graduated from the police academy and was an intern nodded her head seriously, feeling that she was carrying a heavy burden and was in an important position. Lu Ping turned around and walked upstairs. ······ On the second floor of the police station, in the meeting room of the task force. "It's so weird." "Yeah, that's weird." "How could this happen?" "Yes, how could this happen?" "The pit on the far right side of the toilet has been occupied by people since just now. I almost choked to death. I thought there was no one in the police station. How could someone occupy the pit?!" Gan Qi crossed his legs and sat on the chair, puzzled. Zhen Haolin stood on the side and suggested helplessly: "How about you knock on the door and ask?" "It's against etiquette." Gan Qi replied angrily. Zhen Haolin thought for a moment and then boldly spoke: "Brother Gan, why don't you squat in a different pit? As the saying goes, if a toad is running on the ground, it's not squatting anywhere?" "Zhen, you understand me." Gan Qi looked determined:
"I always squat in the pit on the far right. That pit has the best feng shui and is good for laxatives and bowel movements. I feel uncomfortable squatting in other pits." "no!" Zhen Haolin was a little nervous. This colleague was good at everything, serious and responsible, but he was a bit too much for being the best. "Brother Gan, I don't understand. There are clearly three..." bump! Before he could finish his words, the door of the task force's office was suddenly pushed open. Deputy Director Lu Ping walked in and saw the two police officers waiting behind the table with information, and nodded slightly: "You continue, continue the discussion." He waved his hand to Zhen Haolin encouragingly: "What else did you just say?" Zhen Haolin lowered his head and picked up the A4 paper with the crime scene printed on it, and said seriously: "Bureau Lu, I want to say that there are three doubts that cannot be explained." As he spoke, he pointed to photos of the scene. "First of all, judging from the motive, our task force once agreed that the deceased had obviously planned for a long time to kidnap the little girl and succeeded. His purpose was very clear, and his plan had not been completed yet. He had not Zisha’s reasonable motives.” "It is common sense that such a person is unlikely to be purple sand." Director Lu Ping nodded and added: "Besides, I have never seen a suicidal person dress up so weirdly before hanging himself." "That's right. This inference is quite credible." Zhen Haolin pasted the information paper on the blackboard and briefly recorded it with a pen. Then, he pasted two trace inspection results on the door locks and windows in the house next to it. "This is the proof issued by Police Officer Wang [the doors and windows are locked internally, there are no signs of damage or disassembly, and no other passages were found in the room...]" "If he killed the deceased, how did he get in, and how did he get out after killing someone?" This is the core problem. If it cannot be solved, then all the police's conjectures about homicide may only be based on paper. Lu Ping thought for a moment: "If the murderer has the key to this house..." Before the leader finished speaking, Gan Qi interrupted: "Bureau Lu, the door of the room where the deceased was located has a three-section lock. If you lock it with the key from the outside, you can only lock it to the second section. Only by manually locking it from the inside can you lock the third section." This kind of lock is designed for the safety of people inside the house. If the person inside the house does not want others to come in and locks the door in the third section, then even if the person outside has the key, they will not be able to open the door.
"The door of the house at the scene was locked into the third section. It is certain that there is no way to do it from the outside." After Gan Qi finished speaking, the room fell into silence. After a long while, Lu Ping looked at the blackboard again: "What about the windows? The window locks seem to be relatively simple." The windows of the room are rotary handle locks, also called seven-shaped handle locks, which are installed in the house. When locking, the horizontal pressure rod needs to be pressed perpendicular to the ground. At this time, the buckle located at the bearing will close tightly, locking the window and window frame together. "The window lock is made of aluminum alloy. When the window is closed, it fits tightly." Zhen Haolin seemed to have expected that the director would ask: "We tried various methods to close it from the outside - wire hooks, fishing wire, and even female police officers' hair, but they all failed. There is no gap between the window frames and nothing can get through, not even the heat from the radiator. They're all trapped inside." "Moreover, during the initial trace inspection, no line pressure or other abnormal traces were found on the edge of the window frame."
