I am Detective Wu Nan

"Gou Anguo, he entered the office and stayed there for 10 minutes when no one was in the office. What was he doing?" Wu Nan shook the photo, then put it down and continued:"We don't know, we can only guess!"

"I don't know what he did during those ten minutes, but I think he opened the back window of the office and closed it without locking it.……"

"It's a fantasy, right? Why do you say that?" Wu Nan spread his hands,"This surveillance video alone is indeed not enough to prove anything, but...but……"

Snap!

Wu Nan snapped his fingers.

A new picture appeared on the white screen, a total of nine surveillance screenshots!

"At 4:47 pm on December 11, Gou Anguo came out of the general manager's office and walked north!"

"At 4:48 p.m., he walked under surveillance at the corner of the north side of the office building.……"

"At 4:52 p.m., he walked under surveillance on the north side of the factory's No. 1 building.……"

"At 4:56, 5:03, 5:09, 5:15, 5:30, 5:33... Gou Anguo walked through the surveillance areas from the south of Factory Building No. 1, the west corridor, the south of Factory Building No. 2, the north of Factory Building No. 2, the east wall of the factory, and the west wall of the factory.……"

Wu Nan spoke quickly, then slowed down his voice, raised his hand and knocked on the blackboard, and said,"There are nine surveillance cameras in the factory, and within just one hour, all of them captured his figure. What does this mean? After leaving the general manager's office, he walked around the factory in detail and observed the factory's terrain.……"

"More importantly, he observed the surveillance!"

Wu Nan raised his hand again and gestured:"Look at these surveillance screenshots! Gou Anguo has watched the surveillance! Every time he walks under a surveillance camera, he can't help but pay attention to the surveillance! This is not what a normal person should do!"

"People waiting for the elevator like to watch the surveillance. People standing in the corner flipping through their phones may observe their surroundings and look at the surveillance. But people walking by suddenly turn their heads to look at the surveillance, and not just once or twice, but all of them... This should explain something!"

Snap!

Wu Nan snapped his fingers again.

The picture changed!

Wu Nan continued:"And finally, around 5:50, Gou Anguo entered the security monitoring room! He stayed for six minutes and left.……"

"He went to the surveillance again! This time he went directly to the surveillance room. He might just pretend to be passing by and chat a few words, but he must have seen the shooting range of the nine-frame surveillance screen in the surveillance room, what exactly is in the range and what is not captured... What is he thinking? What is he planning?"

"At this point, I deeply suspect that Gou Anguo must have an inseparable relationship with Song Dong's death! He may even be the murderer! Because he was the only person who was caught by the surveillance camera observing the factory terrain and the surveillance shooting area a few days before Song Dong's death! The only one!"

While Wu Nan was speaking, Qian Guogang was quickly flipping through the materials under the podium.

Wu Nan talked about Gou Anguo, and he found the investigation information about Gou Anguo in the photocopied files.

Because Gou Anguo is Song Dong's eldest son-in-law, Song Dong's eldest daughter's family was also investigated, naturally including Gou Anguo. It was not a very in-depth investigation, but some key information was also obtained. Qian

Guogang looked at the information and suddenly froze, and then a faint sneer appeared at the corner of his mouth. The previous investigation data showed that Gou Anguo had sufficient alibi! It was impossible for him to commit the crime!

"I identified Gou Anguo as the key suspect! In the subsequent supplementary investigation, we got……"

"Comrade Wu Nan, may I interrupt you for a moment?"Qian Guogang suddenly spoke.

Wu Nan looked very dissatisfied and glanced at Qian Guogang.

Zhao Chenglong and others also looked at Qian Guogang with dissatisfaction, and He Xubing also tilted his head to look.

Qian Guogang didn't care about Wu Nan's expression, he was just a little kid, he continued:"I read our initial investigation materials after the incident. Gou Anguo recorded a confession. It was clearly written in his transcript that he did come to the factory on December 11 and took the bullet train back to Xihang City that night. On the day of the incident, Gou Anguo had already taken a plane from Xihang to Kyoto. When the victim Song Dong died, Gou Anguo was still on the plane.……"

"According to our subsequent investigation, we can confirm that Gou Anguo did board the plane! This is his alibi, the murderer can't be him!"

Wu Nan looked at Qian Guogang with displeasure.

This idiot! He interrupted his train of thought!

The analysis process of this case is very complicated, and Wu Nan had to explain it step by step, but he was interrupted by Qian Guogang!

"What you asked is exactly what I want to say later. Gou Anguo does have evidence of his absence! I will say it later, don't be impatient!" Wu Nan said expressionlessly, then retracted his gaze, continued to face everyone, and continued to reason!

"I have identified Gou Anguo as the key suspect. In fact, he is not my only key suspect, but the others are no longer important, so I will not talk about them... let’s just talk about Gou Anguo!"

"After additional investigation, I obtained the call records, ID card usage, bank card information, wealth changes, etc. of Song Dong’s eldest daughter Song Qian and her husband Gou Anguo one year before and after the incident... I found something very interesting!"

"After Song Dong's death, a dispute over inheritance occurred. Fu Jiaojiao participated in the inheritance dispute, but ultimately lost the case! Afterwards, Song Dong's food factory was valued at 40 million and transferred to the name of Song Dong's second daughter, while Song Dong's eldest daughter, Song Qian, received Song Dong's two properties in Mohai City, three cars, and some other properties.……"

"Song Dong’s two properties, one in Zhabei District and the other in Pudong District, were both sold in February this year, with a total sales of 28.56 million!"

"In early March, late March, early April, and mid-June of this year, Song Qian transferred 5 million, 2 million, 5 million, and 6 million to the same account respectively, totaling 18 million!"

"The account holder who received the 18 million yuan in payment was named Gou Anhua!"

An unfamiliar name, but obviously related to Gou Anguo!

Wu Nan looked at Qian Guogang and said,"This Gou Anhua is Gou Anguo's younger brother, one year younger than Gou Anguo!"

"It's very strange!" Wu Nan paused, and then said lightly:"Why did Song Qian make multiple payments to her husband's brother? This must be related to her husband Gou Anguo!"

"So... why did Gou Anguo give his brother so much money? If he gave it once, it was because he suddenly became rich, the couple had a good relationship, and Gou Anguo could make the decision on Song Qian's inheritance, so Gou Anguo took care of his brother and gave him money, but... how could he give it so many times? He had already given 18 million! Who would be so generous?"
