Escape From the Library

【Construction Site Mystery-04】

Ke Shaobin's guess made everyone stunned - if the murderer had supernatural powers and escaped from the building like Qin Lu's "plate movement", of course they could perfectly avoid surveillance, and they would rely on Qin Lu's skills to copy the data of.

Everyone subconsciously turned their attention to Qin Lu.

Qin Lu hurriedly said: "The tectonic plate movement is a skill of the geography department. The upper limit of the number of people in this exam is 12, and our research group has 11 places, and then a student from the geography department will be matched as the murderer? This... is unlikely Bar?"

Jiang Pingce said calmly: "Impossible. The maximum number of people in the examination room is 12. Obviously, the subject group of 12 people in the third level can take the test directly, and the subject group of 8 people in the second level and 4 people in the first level can be matched together to enter the examination room. We The team is not full at present, it is because we have not found all the teammates and have a vacant spot, but most of the teams will enter the examination room at full capacity."

Zhuo Feng echoed: "That's right, I heard from Qin Lang that Binjiang Normal University's team is also preparing to be promoted to the third level, with a maximum of 12 people. If their team enters this examination room, won't there be no place for the murderer?"

Jiang Pingce looked at Yue Xingwen: "For the exam of the same class, will the library modify the plot line for our 11-member team alone, and match another murderer in?"

Yue Xingwen shook his head and said: "It shouldn't happen, right? That would be too unfair. The change in the examination room is only the name of the characters and the details of the plot, and it will not change so much that the examinee becomes the murderer. The maximum number of people in the examination room is 12, and it does not mean that there must be 12 people. Candidates. I think there should be only 11 of us in this examination room, and the murderer still has to be found among other people."

Everyone nodded, Jiang Pingce and Yue Xingwen's analysis was also very reasonable.There was a reminder in the course "Death Code" of the School of Statistics last time. If there are not enough candidates, 4 people can also open the examination room, which proves that the number of people in the examination room is not stipulated, and will be adjusted appropriately according to the matching situation.

Everyone looked at Ke Shaobin.Ke Shaobin's ears turned red, and he whispered, "I'm just guessing. The murderer appeared and disappeared out of thin air. It's amazing. I thought he had supernatural powers, cough cough."

Everyone: "..."

Xin Yan glanced at him, and said flatly, "Some strange ideas often pop up in your head."

Ke Shaobin adjusted his glasses, blushed and softly argued, "I'm flexible in thinking!"

Yue Xingwen patted him on the shoulder with a smile: "It's okay, brainstorming, everyone can analyze everything that comes to mind. Suppose, the conjecture that the murderer has supernatural powers that Ke Shao said is not true. Then, how did the murderer avoid it?" What about monitoring?"

Zhang Xiaonian suddenly asked: "There are only three entrances and exits on the ground of this building, and the current surveillance coverage can only take pictures of the entrances and exits on the ground, but what if—— he doesn't go to the ground?"

Yue Xingwen's eyes lit up, and he immediately thought of another possibility: "The underground parking lot hasn't been built yet?"

The project of Xinyue Plaza is huge. In order to facilitate parking for guests who drive, the underground parking lot is planned as a negative two-story structure.The foundation of the whole project was laid very deep. Right below the current construction site and below the cross-shaped pedestrian street, a large area of ​​parking lot was hollowed out.

If the murderer is hiding in the underground parking lot, there is really no need to enter the building through the entrance and exit, and there is no need to come out.

During the period between the death of the deceased and the arrival of the police, the murderer could not be photographed by surveillance. He could find a manhole cover leading to the ground and sneak out while no one was paying attention.

Thinking of this, Yue Xingwen immediately said: "Young Master Ke, open the design drawing of the underground parking lot."

Ke Shaobin turned on his laptop and called up the project design drawings. Zhang Xiaonian quickly found the construction drawings and design renderings of the underground parking lot from a large number of pictures.

The Xinyue Building has just been topped out, and only a prototype of the underground garage has been built. The entire underground garage is a "convex"-shaped structure. The raised area is directly under the Xinyue Building, and the remaining rectangular area is under the pedestrian street.

The garage has many square columns supporting the weight of the building, and a large number of drainage pipes are distributed in the ceiling.Not to mention the markings on the parking spaces, the floor of the garage has not even had time to paint the cement—the construction progress of this underground garage is currently less than 30%.

The pedestrian street is also under construction. Jiang Pingce pointed to the location of the pedestrian street on the map, and said: "Enter the underground garage from the pedestrian street, go all the way to the second floor directly below the Xinyue Building, go up the stairs, kill people, and then If you go downstairs and escape through the underground passage, you can perfectly escape all surveillance cameras."

Yue Xingwen asked: "The Pedestrian Street is far away from the dormitory area. How long does it take him to walk from the dormitory to the Pedestrian Street, from the underground passage to the Xinyue Building, and then escape after killing someone?"

Jiang Pingce calculated carefully, and said, "If you jog all the way, it will take about half an hour to go back and forth. That is to say, the murderer was not in the dormitory for at least 30 minutes. When the police asked today, whose alibi was suspicious?"

Yue Xingwen immediately took out the notes in his pocket.During the police investigation just now, he had been recording information, which was just in handy at this time. Yue Xingwen analyzed the recorded information in turn: "Most of the workers said that they were sleeping very deeply at the time, and they wondered if their roommate left. Yes, there are only three special dormitories."

"The first one, the workers in the 116 dormitory woke up at 4:5 in the morning and found that there was no one in the next bed. The one who was not in the room, named Zhao Qiang, came from the same village as the deceased Zhao Dayong. He explained to the police that he went to the Toilet. But his roommate said he didn’t come back until around [-] o’clock. His explanation to the police was that he had diarrhea.”

"That is to say, he left for more than half an hour at the time of the incident? The reason was diarrhea?" Jiang Pingce wrote down the key, and said calmly, "No one can prove that he went to the toilet."

"Well, he is indeed suspicious." Yue Xingwen continued, "The second one is an electrician named Long Rui in the 207 dormitory. He also left after 4 o'clock. He said he was awakened by a nightmare in the middle of the night and couldn't sleep. I went to find a corner outside to smoke, and there are still ash left by him."

"The third one is the woman who screamed at the scene of the crime today, named Zhao Xuemei, also from the same village as the deceased. Her roommate said that she was not there when she woke up around 4:5 in the morning, and she screamed at 1:[-] , disappeared for [-] hour during the period.”

Yue Xingwen paused for a moment, then looked up at everyone: "The other workers are not sure yet, most of them are asleep and don't know the situation of their roommates. But the whereabouts of the three people who have left at the time of the incident have been revealed. Doubtful."

Liu Zhaoqing rubbed the back of his head and complained, "Zhao Dayong, Zhao Liang, Zhao Qiang, Zhao Xuemei... all of them are named Zhao. Is their village called Zhaojia Village?"

Zhuo Feng said: "There is Wang's Village in my hometown, and 80% of the villagers are named Wang. It seems that these people are all from Zhao's Village. Maybe they have private grievances, so we need to focus on them."

Yue Xingwen wrote down the names of the characters that appeared so far on a piece of paper, and began to analyze them one by one: "The deceased Zhao Dayong was a 35-year-old cement worker. According to the evaluation of the workers, he was usually introverted and taciturn, and had no disputes with anyone. This is just On the surface, it is still unclear who he has had grievances with in private."

"Suspect No. 1 Zhao Liang, 18 years old, nephew of the deceased. He was in the building at the time of the incident, and was caught by Pin Ce. If he was the murderer, he would have pushed his uncle downstairs. When he wanted to escape, Pin Ce I found... the timing makes sense, and he can explain it if the surveillance didn't capture it, but the motive for committing the crime is still unclear." Yue Xingwen looked at Jiang Pingce, "What do you think?"

"Both his parents died and he was brought up by his uncle. What was his motive for killing his uncle? Unless his parents left him a huge amount of property and his uncle took it all by himself. But the workers said that his family was very poor, and his uncle was so poor that he married Looking down on a wife is not like killing a family member for the sake of property." Jiang Pingce said calmly.

"Could it be that his uncle abused him for a long time? For example, his uncle is actually a perverted pedophile. He molested and bullied him since he was a child. He endured it for a long time because he was weak and unable to resist. Now he grows up Finally, I couldn't take it anymore, so I just followed my uncle to the construction site, looking for an opportunity to push my uncle downstairs and fall to his death?" Ke Shaobin analyzed seriously.

"..." Yue Xingwen helped his forehead helplessly, "In this case, he does have a motive for committing the crime."

"It's more reasonable than the speculation that the murderer has supernatural powers." Jiang Pingce said with a deadpan expression.

"Ahem, I was talking nonsense." Ke Shaobin made a "zipper" movement on his mouth, and lowered his head embarrassedly.Beside, Lin Manluo suppressed a smile and said, "Xiao Ke, you have a rich imagination, it's a good thing to raise more conjectures, it will help everyone to open their minds, don't be shy."

"Both parents are dead, the poor child has no one to rely on. After being bullied by his uncle for many years, he finally couldn't bear to push him downstairs? The speculation is valid, but we still have to investigate how the relationship between Zhao Liang and his uncle is. To be determined." Yue Xingwen drew a circle on the 18-year-old boy's name and said, "Let's analyze the next one."

"Zhao Qiang, a 30-year-old cement worker, lived in the same village as the deceased. He was about the same age. He left the dormitory for half an hour at the time of the incident. The reason was that he went to the toilet to have a diarrhea. No one confirmed whether his words were true or false," Yue Xingwen said.

"Getting up to go to the bathroom at 4:[-] is not credible," Jiang Pingce said.

"Well, this person has to continue the investigation." Yue Xingwen marked Pending on the side, and then said: "Suspect No. 3, the screaming Zhao Xuemei. If she is the murderer, she has to run from the dormitory to the pedestrian street. Lurking in the underground garage, climbing upstairs and pushing an adult man down, then running from the underground garage to the pedestrian street, lifting the manhole cover and crawling out, and then running back to the scene where Zhao Dayong fell to his death and screaming...is this too troublesome?"

Since the surveillance did not capture anyone entering or exiting the building, Zhao Xuemei still had to enter through the underground passage on the side of the pedestrian street if she wanted to commit a crime. She killed people around 5 o'clock, and appeared at the scene screaming at 5:[-]. She had to run back and forth at least three times.

Xu Yi rubbed his forehead deeply, and said: "Even if I run with the split body, I will be exhausted after running so many times."

Yue Xingwen looked at Jiang Pingce: "When we arrived at the scene, she didn't seem very tired, did she?"

Jiang Pingce nodded: "She just has pale lips and a terrified face, and she doesn't appear to be panting after strenuous exercise. If she is the murderer, there should be too little time."

Climbing up and down the 7-storey building, going through the entire underground garage, and then running back to the scene of the crime screaming, the whole journey is several kilometers, Xu Yishen would be exhausted and panting.

It is impossible for a thin woman to run back and forth three times and still breathe steadily.

Yue Xingwen said: "Suspect No. 4, Long Rui, was not in the same village as the deceased. He was an electrician. It was strange for him to say that he went to smoke. The ash can't be used as evidence. He can put a pile of ash there in advance."

Yue Xingwen stopped writing, and concluded: "Currently, Zhao Xuemei's suspicion is relatively low; Zhao Liang, Zhao Qiang, and Long Rui, three people, each of you should ask other workers on the construction site separately, and investigate carefully."

After Yue Xingwen assigned the task, everyone went out to visit the nearby workers to investigate.

Due to the murder case on the construction site, work must be suspended today. The workers are obviously a little emotional, and many leaders appeared on the construction site to appease everyone's emotions.

When Yue Xingwen took everyone out, he saw a leader wearing a white hard hat holding a loudspeaker in his hand, standing in the middle of the construction site and shouting: "Everyone, don't panic, Zhao Dayong fell from the construction site, it was just an accident! We are cooperating The police are fully investigating! When the results of the investigation come out, we will definitely compensate his family in accordance with laws and regulations!"

Jiang Pingce moved closer to Yue Xingwen's ear and whispered, "Mr. Zhang who came here yesterday."

Zhang Zhiwei, the person in charge of the construction party of the Xinyue Plaza project.He is dark-skinned, muscular, about 178cm tall, with an obvious mole on his cheek, and looks shrewd and capable.

Mr. Zhang's words are very official.

Suddenly, someone shouted loudly in the crowd: "Mr. Zhang, when will the wages owed to us be paid?!"

Zhang Zhiwei held the microphone and smiled all over his face: "Don't worry, everyone, the developer has promised to settle the payment for the second phase of the project. We have been negotiating with the developer, and we will definitely not let everyone's hard work go to waste!"

The crowd immediately voiced dissatisfaction: "Years ago? There are still several months before the Chinese New Year. Are we going to drink Northwest Wind in the second half of the year? It's been half a fucking year, and my wife and children are still waiting for me to send money home to pay for school fees! "

"That's right, my parents need money for their illnesses. If we don't pay wages, we'll just go on strike and quit!"

"Yes, quit!"

"The safety of the construction site is not guaranteed. Zhao Dayong fell to his death today, and it might be our turn tomorrow!"

"I didn't get any of the hard-earned hard-earned money, and it's not worthwhile to spend my life on it!"

"Pay wages, pay wages!"

A group of workers shouted in unison, and the whole construction site was in chaos.

Mr. Zhang wiped the sweat from his forehead and picked up the trumpet to calm everyone's emotions, but obviously, the death of Zhao Dayong aroused the anger of the workers who had been suppressed for a long time. Dropped and ran away in desperation.

Yue Xingwen looked at his back as he was being escorted away, frowned slightly, and said, "The workers were owed wages, and it lasted for several months?"

The news that broke out made everyone look dignified.

Xu Yishen suddenly said: "The government sells the land ownership to the developer. The developer makes a good project plan, and the construction unit bids for the construction. Usually, after the government sells the land, it no longer participates. The construction unit is paid by the developer. There are often conflicts of interests among the parties, and disputes over wage arrears.”

Yue Xingwen looked back at him: "Brother Xu understands this very well?"

Zhuo Feng laughed and said, "His father is in the real estate business. He doesn't want to inherit the family business. He is admitted to the Academy of Biological Sciences to study genetic engineering and wants to be a scientist."

"Well, it's not that great, I'm just more interested in genes." Xu Yishen said modestly: "And I have no talent at all in business, and the company can go bankrupt within three years."

"What do you think, brother?" Yue Xingwen was returning to the topic.

"There are many reasons why developers default on project payments. First, some developers develop projects on multiple plots at the same time, and the mortgaged properties are not yet available for bank loans, which leads to a break in the capital chain and cannot pay the construction party; second, The budget negotiated by the construction unit and the developer exceeded the standard. For example, the first phase of the project was originally agreed to be 8 million yuan, but the construction party spent 9 million yuan. The developer did not approve the construction party’s material quotation. It is impossible to pay during the period." Xu Yishen paused, and said, "There is also a more extreme situation, that is, the construction party or developer, and the person in charge runs away with money."

Yue Xingwen pondered for a moment, then said: "No matter what the reason is, the workers haven't received their wages for half a year, and the arrears of wages is a certainty. Then, could Zhao Dayong's death be related to this?"

He looked at Jiang Pingce beside him: "Someone wants to influence the construction progress in this way?"
