"Old Sun, what are you doing? You'll scare the child!" Zhao Chenggong couldn't help but become stern.
"Alright, alright, alright. You guys go on, you guys go on. You guys listen to a nine-year-old child give you a lesson. I'm leaving!”After Sun Meng said that, he pointed at Wu Xinyan with his finger, giving her a warning. Then, he turned around and walked out.
Sun Meng was an old criminal police officer. He was about the same age as Zhao Chenggong. Although his position was not as high as Zhao Chenggong's, everyone knew his temper!
"Wait a minute!" Wu Nan shouted.
At the same time, he jumped over the sofa and jogged past the others. He quickly jumped to the door and blocked Sun Meng's way. He shouted,"Don't go!"
"Xiao Nan, what are you doing?" Wu Xinyan shouted.
Female police officers were discriminated against in the first place. Wu Xinyan was only able to be transferred here because of her uncle's help. There was a lot of criticism in the station, saying that she was a pretty face!
Now, her younger brother was arguing with her leader!
Wu Xinyan was so angry that she was about to cry!
"Hey, hey, hey, let me tell you! You can't leave!" Wu Nan pointed at Sun Meng fiercely.
"What do you mean?" Sun Meng looked at Wu Nan, then at Wu Xinyan.
"It's your business whether you listen to me or not, but you broke my vase.”Wu Nan said righteously.
"Xiao Nan, don't mess around…"
"Sis, don't worry about it…"
Sun Meng was furious!
" Let me tell you, I'm nine years old this year and I'm in primary school. If you dare to touch me, I'll immediately lie on the ground and not get up. I'll even post on Weibo. I'll let the entire country know that you're a police officer who hit a child…You'll be fired immediately…" Wu Nan spoke very quickly and logically!
Sun Meng's face turned purple from anger.
What to do?
He really didn't dare to attack Wu Nan! If Wu Nan was twenty years old, he would have slapped him!
But Wu Nan was only nine years old!
"Okay, okay, okay. I'm Wu Xinyan, I've seen it for myself. Your family is really powerful.”Sun Meng spoke very quickly, and his voice was a little shaky. It was obvious how agitated he was. As he spoke, he opened his briefcase and took out 50 yuan.
Pa!
Sun Meng slapped the fifty yuan on the cabinet at the side and shouted at Wu Nan,"Is that enough?"
"Old Sun, don't scare the child!" Zhao Chenglong added.
"Enough!" Wu Nan tiptoed and reached out his hand to take the fifty yuan. Then, he stepped aside and walked past Sun Meng. He even said to Zhao Chenglong,"Uncle, are you leaving too?"
Wu Nan walked behind the coffee table and sat on the sofa. He said,"If you don't want to leave, I can tell you. I know who the murderer is…It's Wang Shengli, the resident of Unit 501 downstairs!”
Zhao Chenglong looked at Wu Xinyan, wanting to say something.
Upon hearing Wu Nan's words, he turned around and looked at Wu Nan!
Sun Meng had already walked out of the door and stopped in his tracks.
"Little Nan, don't talk nonsense.”Wu Xinyan immediately refuted. Wu Nan's previous deduction could only be said to be a suspect. The murderer was a qualitative term, so he couldn't be directly said!
Chenglong raised his hand to signal Wu Xinyan to keep quiet, then walked towards Wu Nan.
"Xiao Nan, how do you know who the murderer is? What did you see that day?" Zhao Chenglong sat beside Wu Nan.
Wu Xinyan also walked over and stared at Wu Nan, afraid that he would say something stupid.
Sun Meng, who had already walked out, walked back and stood at the door without saying a word. He wanted to listen!
The other two young comrades were also standing near the door.
"I said, didn't you want to leave?" Wu Nan turned to look at Sun Meng.
Pa!
Wu Xinyan hit Wu Nan on the back of his head and scolded,"You naughty child, tell me quickly!"
Helpless!
" Okay, okay, okay. Sis, pass me your bag..." Wu Nan waved his hand.
Wu Xinyan handed the bag to Wu Nan.
Wu Nan took out the files from inside and separated them into a few pieces, placing them on the coffee table. Wu Xinyan had thought that these files were messy…but they weren't. Wu Nan had organized them himself, and the important things were all on them!
"Can you not interrupt me when I'm talking?”Wu Nan said.
"Yes, say it!" Zhao Chenglong chuckled. He knew how to coax children. He also had a daughter at home who was about the same age as Wu Nan.
"First, scream!" Wu Nan began to say," A woman's scream is indeed around 70 decibels. In fact, it's about the same for a man as long as he can squeeze his throat and scream. But why is a woman's scream more ear-piercing? Because the frequency is higher…"
"Actually, this is nonsense. What I wanted to say was that my sister said before that it was impossible to hear screams on the first floor!”
"You might be skeptical about this, but I think it's certain…The first floor can't hear it, but why did the first floor hear it? Because the sound did not come from room 602, but from the sixth floor corridor!”
"Only the first floor can hear such a scream from inside the corridor because the top and bottom of the corridor are one space! The sound can spread throughout the entire building!"
"Then a new question has arisen. Zhang Xia died in the living room of Room 602. How could she scream in the corridor? This was the key point. The scream did not come from Zhang Xia, but from the murderer! However, this doesn't mean that the murderer is a woman…"
" The murderer could be a man. The scream could be a kind of recording, a kind of network audio. The most convenient way is to download it with a mobile phone and play the audio…"
"A new question has arisen. If the murderer used the device to scream in the corridor on the sixth floor, how did he escape?”
"According to my deduction, he didn't run at all! Because he was very likely one of the neighbors who arrived at the scene first! If the murderer lived on the fourth floor, he would run back to the fourth floor after screaming…It's very likely that the neighbors on the fifth floor who just left the house would see him, but from the statements of these neighbors, there's no such thing…"
"At this point, we can basically lock the murderer into four families!”
" According to these statements, the first to arrive at the scene was Uncle Wang on the fifth floor and Auntie Li on the seventh floor…This can prove my speculation…If the murderer came from the fourth floor, he would definitely be noticed if he ran down. If he really ran, the sound in the corridor would be very loud…But no one heard the sound of running in the corridor…"
"Therefore, it means that the murderer did not leave quickly after creating the screams in the corridor. In other words, the murderer was one of the first people to arrive at the scene…the seventh floor or the fifth floor!!”
"There are two families on the seventh floor. Both of them live in the elderly. Their children occasionally come to visit. Usually, it's the elderly couple. The possibility of committing a crime is very low.”
" Fifth floor, Uncle Wang and Uncle Sun. Uncle Wang came out first…"
"Look again, Uncle Sun's family of three is harmonious. Uncle Wang lives alone and has been single for many years…In this case, Zhang Xia and Aunt Zhang didn't have any grudges with anyone and didn't lose any property. In other words, the possibility of murder is very high, including…murder due to emotions!”
"Look at the statement again! These statements can prove that Uncle Wang was the first to arrive at the scene, that Uncle Wang was the one who guessed that something had happened to Auntie Zhang, and that he was the one who kicked the door open and took a few steps inside…And I think that he is also the one who is suspected of committing the crime. Uncle Wang downstairs, Wang Shengli!”
"Let me go through the situation of the case!”Wu Nan paused and took a sip of water before continuing," At around 8:50 pm on the 13th of July, Wang Shengli was discussing something in Zhang Xia's room. Due to some conflict, Wang Shengli lost control. He picked up the fruit knife on the coffee table in the living room and stabbed Zhang Xia twice in front of her. The last cut was on Zhang Xia's neck..."
" Zhang Xia didn't die immediately. Instead, she struggled on the ground. Wang Shengli wiped off the fingerprints on the handle of the knife and left Zhang Xia's house. He quickly returned to his own house, took a shower, and changed his clothes. He then returned to the sixth floor and created a scream. Then, he quickly returned to the fifth floor…"
"At this moment, Uncle Sun opened the door on the fifth floor to check on the situation. He happened to see that Wang Shengli had already gone out…Actually, he had just come down from upstairs!”
" The entire building was alarmed…Everyone came to the door of Room 602, knocked on the door, and smashed it. After a while, Wang Shengli, who had been blocking the door, was the first to kick it open and see the dead Auntie Zhang…"
Pa!
Wu Nan closed the folder and said indifferently,"That's it, so Wang Shengli is the murderer!”
"In addition! According to the wounds on Auntie Zhang's body and the amount of blood, the murderer must have sprayed blood on his body. He needed to take a shower and change his clothes. According to the psychological pressure the murderer had suffered at that time, the murderer was likely to take off his clothes completely and constantly flush to ensure that there was no victim's blood on his body. If he did not do this, he might feel that he was not clean! If his bloodstained clothes weren't burned, they should have been washed repeatedly…"
"Therefore, I suggest that you check the water consumption of all the residents in the entire building on the day of the crime. The focus is on Wang Shengli's house.”
"That's it!" Wu Nan finally finished speaking. He held the glass of water and began to drink again.
The room was silent!
