He Xubing looked at the stage. It was really a kid!
Primary school students!
He didn't have stage fright. His opening speech was not bad. It was very stable. He didn't know who taught him that! He Xubing was expressionless. If there was no conclusion to this matter today, then the Criminal Investigation Division really needed to make some adjustments!
The other hundred criminal police officers were also dumbfounded!
What was going on?
A primary school student is here to teach the criminal police team?
What happened to Captain Zhao? How badly had his brain been kicked by a donkey to do such a thing?
……
Wu Nan turned around and looked at the picture projected on the white screen. He raised his hand and gestured, then said," Everyone, please take a look. This is the network of Song Dong, the victim of the 1213 murder case…"
" According to the investigation, the victim, Song Dong, male, 51 years old, owner of Xinli Food Factory in Zhabei District... On December 13th last year, he was strangled to death in his office, and his body was later found by the security guards..."
" According to the police's preliminary investigation, we've already ruled out dozens of suspects and four key suspects…Therefore, I've re-analyzed Song Dong's social connections and family situation…"
"From what we know, Song Dong's death was nothing more than a revenge murder, a murder of love, or a conflict of interest or money! The possibility of an acquaintance committing the crime is as high as 90%, but we can't rule out the possibility of hiring someone to kill…"
Wu Nan picked up a piece of chalk and wrote the word 'acquaintance' on the small blackboard beside him!
He turned around and continued.
" Song Dong divorced thirteen years ago. At that time, he didn't have the huge assets he had before he died, so his ex-wife, Feng Dongmei, only got less than two million yuan and took her two daughters with her. Song Dong's relationship with his daughter was very cold until four years ago, when Feng Dongmei passed away due to liver cancer. Song Dong and his daughter gradually contacted each other more and their relationship gradually eased…"
" Personally, I think that Song Dong's death is most likely because of money. In my analysis, the main suspect is the financial manager of Xin Li Food Factory, Fu Jiaojiao. Fu Jiaojiao was Song Dong's lover and participated in the battle for the inheritance after Song Dong's death. However, after my analysis of the files, I found that the living Song Dong has more benefits than the dead Song Dong in dealing with Jiaojiao..."
"Therefore, I shifted the focus of my analysis to Song Dong's family. He has two daughters who don't get along well with each other…Look at the picture!”Wu Nan knocked on his back and continued.
"Elder daughter, Song Qian, female, twenty-seven years old. She got married four years ago, and her husband lived in peace. Before Song Dong died, the two of them settled in Xihang City and opened a large-scale chain fast food restaurant.”
" The second daughter, Song Yang, female, 26 years old. She got married three years ago. Her husband, Zhang Ke, was also married before Song Dong's death. They were both working in foreign companies in Xihang City and had not given birth yet..."
"I remember a famous saying,'Make a bold hypothesis and be careful to verify it.' This saying is very suitable for criminal investigation cases.”
"I suspect that Song Dong's death has something to do with his two daughters. Actually, I also suspected a few others, but that's not the main point now.”
" Firstly, they don't have a good relationship with Song Dong. Back then, Song Dong divorced because of domestic violence. It can be said that Song Dong was a shadow in their childhood. Before Song Dong's ex-wife died of illness, Song Dong barely saw his daughter..."
"Secondly, Song Dong might remarry! His remarried partner was Fu Jiaojiao!”
"Song Dong is fifty-one years old, and Fu Jiaojiao is thirty-six years old. The two of them are fifteen years apart. Fu Jiaojiao is a woman who loves money very much! They were dressed fashionably, and Song Dong was in poor health due to years of fatigue. Before he died, his temples had already turned white. If the two of them were really married, it could be said that they were an old couple!”
"Third! "According to the police's previous investigation and evidence collection, the police obtained Fu Jiaojiao's phone number and the call records for the year before Song Dong's death. From these call records, we can know that Fu Jiaojiao and Song Dong's two daughters, Song Qian and Song Yang, had frequent calls three months before Song Dong's death…"
" According to the records collected by the police, Fu Jiaojiao had a fierce phone argument with Song Dong's two daughters…Song Qian, Song Yang, and their husbands all came to Xin Li Food Factory and had a conflict with Fu Jiaojiao…"
"Why?" "Because of money!" Wu Nan asked.”
" They're worried that Fu Jiaojiao will cheat Song Dong of his money. Once they get married, although the food factory is Song Dong's pre-marital property according to the marriage law, all the profits from the food factory will become the joint property of the husband and wife after marriage. Without Fu Jiaojiao, according to the inheritance law, Song Dong's property, whose parents have passed away, will be inherited by his two daughters in the future…"
"Fu Jiaojiao once embezzled public funds! Therefore, he even quarreled with Song Dong, but nothing happened in the end.”
" Song Dong's two daughters saw this Fu Jiaojiao as a thorn in their flesh. However…Fu Jiaojiao was not harmed. The one who died was Song Dong…"
At this point, Wu Nan snapped his fingers." Alright, let's stop here. Let's look at it from another angle…"
The criminal police officer in charge of the slide show changed the picture.
New pictures were shown on the white screen. The first one was a sketch of the Xinli Food Factory, including the location of the surveillance cameras. It was an aerial view!
" Look, there are a total of nine surveillance cameras in Xinli Food Factory..." Wu Nan pointed and said," From this topographic map, the entire factory is under surveillance. Only some places such as the back of the factory, the back of the office building, the corner, and so on are not under surveillance..."
"This picture is enough to prove that the person who killed Song Dong was someone Song Dong knew. He was someone who was very familiar with the Xinli Food Factory. He knew the location of the surveillance cameras and was able to sneak into the food factory smoothly. Then, he avoided the surveillance cameras and left quietly without being discovered..."
"It's an acquaintance! Very familiar ones!" Wu Nan knocked on the blackboard and continued.
" Song Dong's time of death was around 9:10 p. m. According to the police's analysis, the murderer climbed into the office through the back window, strangled Song Dong from behind with a rope, and then left through the back window…The window was not locked…"
"Then the question arises. How did the murderer open the window?”
Wu Nan was silent for a moment. He glanced at everyone and said,"This is very important!"
"It was December, and the temperature in Mo Hai City was between 10 to 15 degrees Celsius. It was very cold, very cold for southerners. After Song Dong died, the police arrived at the scene and confirmed that the air conditioner was on.”
" However, there are surveillance cameras that can prove that no one entered Song Dong's office before and after his death. If there was, then the case of window flipping is not valid. There's no need to flip the window…If the case of window flipping is valid, it means that the window was unlocked in advance. It's just that it was closed and stuck. It's not locked…"
" Therefore, I checked the factory's surveillance cameras seven days before Song Dong's death..."
Wu Nan snapped his fingers again!
Change the photo!
The photo on the white screen was replaced by a screenshot of a surveillance camera. It showed that someone was about to enter the general manager's office!
" This is a screenshot of the surveillance camera at 4:37 p. m. on December 11th, two days before the crime. The screenshot shows that this person entered Song Dong's room... Ten minutes later, he came out of the room..."
"According to the surveillance footage, Song Dong left the factory at three o'clock in the afternoon and never returned. There's no one else in the office at the moment, so why did this person enter Song Dong's room? Take the information? Arrange the documents? Clean up the room? No, no, no…I've already filtered out those people…This person isn't an employee of Xinli Food Factory, but…Maybe the video isn't clear, so you can't tell, but after comparing the characteristics, I can tell you…"
"This person is Song Dong's eldest son-in-law, Gou 'an Kingdom!”
Wu Nan took out a photo from his folder and showed it to the crowd.
The room was filled with low but noisy discussions, like the buzzing of flies.
