I am Detective Wu Nan

"My dear sister, you really took great pains to attack your brother!"Wu Nan rolled his eyes. This kind of unsolved case, without sufficient evidence, is unlikely to be solved by reasoning alone! It is different from the case of Zhang Xia's death!

That is a current case, and the various clues and details have not been destroyed. However, in the homicide case at the end of last year, many clues have been completely broken with the passage of time. Those suspects have been cleared of suspicion and may have left Mohai City. It is very difficult to find them and question them. How to solve it?

Despite this, Wu Nan still opened the file of the 1213 homicide case!

What he is good at is finding logical errors, so as to conduct logical reasoning in all aspects, and pay attention to details, because he is a criminal genius. He knows how to commit crimes, and can guess how others commit crimes!

Just like, a habitual thief must be very accustomed to what thieves do. If a habitual thief is asked to squat at the bus station, he can definitely find his colleagues at the fastest speed!

And Wu Nan's criminal ability is comprehensive!

1213 murder case!

The deceased, Song Dong, male, 51 years old, was the boss of Xinli Food Factory in Zhabei District. He had a fortune of about 80 million yuan, had been divorced from his wife for many years, and had two married daughters. At around 10 pm on December 13 last year, factory security guard Zhou Lu found the boss Song Dong dead in the general manager's office during his patrol, and then called the police... The police arrived at the scene shortly afterwards.

According to the on-site forensic investigation, Song Dong was sitting on a chair and was suddenly strangled by a plastic rope from behind, suffocating to death!

The time of death was about 9:10 pm.

He was strangled alive!

Police Fang found more than a dozen footprints at the scene, most of which were left by people entering and leaving the general manager's office during the day. However, several footprints were found behind a chair, which were confirmed to be from the murderer. They were size 43 hiking boots.

After investigation, it was confirmed that Song Dong returned to the factory at 4 pm that day, had dinner in the cafeteria at 6 pm, and returned to the office at about 6:30 pm. He never came out again until the security guard found his body!

The last person to enter the general manager's office was Kang Tingting, the head of the raw material procurement department. Kang Tingting was 42 years old and had worked at Xinli Food Factory for many years. The last time she entered the office was about eight o'clock, and the time she left was about eight twenty.

According to Kang Tingting's transcript, she reported to Song Dong about the return of expired flour a few days ago. The main reason why Song Dong kept the factory busy so late that day was mainly because of this incident!

The police retrieved all the surveillance cameras of the factory.

There was no surveillance near the general manager's office, but there were surveillance cameras in the factory building, the main gate, and every corner... The police did not find any suspicious people entering or leaving the general manager's office before and after the incident. There were no signs of prying on the doors and windows of the general manager's office, but according to the on-site investigation, the back window of the office was not locked and could be opened from the outside.

Within half a month after the incident, the police collected hundreds of transcripts and summoned twelve key suspects. Finally, four people were confirmed as suspects, namely Li Tai, a former employee of the factory, Feng Qun, the owner of the flour mill, Mu Dali, the owner of the loan company, and Fu Jiaojiao, the finance of the flour mill.

Li Tai was a former employee of the flour mill. He resigned for personal reasons, but because the factory withheld his salary for one month, he came to the factory many times to ask for an explanation. The last time was three days before the incident, and Li Tai was beaten!

Feng Qun, the owner of the flour mill, sold a batch of flour that was about to expire to Xinli Food Factory two months ago. It was not until a few days before the incident that the warehouse manager of Xinli Food Factory noticed that the flour had expired half a month ago. After that, Xinli Food Factory had a dispute with the flour mill.

Mu Dali, the owner of the lending company, Song Dong borrowed a sum of 3 million in cash from Mu Dali as early as a year ago.

Later, Song Dong repaid the money and paid a full 2 million in interest.

However, Mu Dali's lending company was legal on the surface, but in fact it was illegal usury.

There was a gap between the principal and interest repaid by Song Dong and the principal and interest calculated by Mu Dali's company.

In the end, there was still a difference of more than 400,000 in interest that was not paid back!

Song Dong believed that Mu Dali had committed contract fraud and it was not clearly written on it, so he refused to give the last 400,000. Because Song Dong was also quite powerful, the matter ended up in vain. However, according to the confession of the food factory employees, Mu Dali had sent people to the food factory many times, and there have been rumors that he would retaliate!

The last key suspect is Fu Jiaojiao, the finance of the flour factory!

Fu Jiaojiao is 36 years old. She joined Xinli Food Factory three years ago. She was an ordinary employee. As a result, she hooked up with Song Dong and became the financial director. Everyone in the factory knew that Fu Jiaojiao was Song Dong's mistress!

The reason why Fu Jiaojiao was suspected to be directly related to Song Dong's death was because Fu Jiaojiao had embezzled public funds from Xinli Food Factory many times. The day before the incident, an employee saw Fu Jiaojiao and Song Dong quarreling in the office, and Song Dong beat Fu Jiaojiao!

After Song Dong's death, Fu Jiaojiao also joined the battle for Song Dong's inheritance, claiming that she and Song Dong were de facto husband and wife!

Four key suspects!

Because of these four people, the police investigated dozens of people! They all had close relationships with these four people, but in the end, all the clues were broken... All of them had evidence of alibis, and all of them could prove their innocence!

Wu Nan repeatedly looked at these documents, photos, surveillance screenshots, and so on!

Interesting!

This case doesn't seem to be as difficult as Wu Nan thought! Because the deceased Song Dong was definitely not killed by home robbery, random killings, revenge on society, etc.! There are only three reasons for his death: love, hatred, and money!

Wu Nan's thoughts raced as he read these contents.

"Sister, the four key suspects you listed……"Wu Nan suddenly spoke

"What?"Wu Xinyan said

"Perhaps the direction of the investigation is completely wrong!"

"what have you found?"

"Not yet!"

Pa!

Wu Xinyan slapped Wu Nan on the back of the head.

"What do you have to say?" Wu Xinyan said unhappily

"Actually, it’s not……"Wu Nan added.

In fact, from the perspective of a criminal, Wu Nan has identified at least a dozen suspects through these files... Every person he suspects has enough motives to commit the crime in his mind, although some of the motives are his guesses based on"human nature".……

"Sister, take me to the Criminal Police Team."Wu Nan said

"What are you going to do?" Wu Xinyan looked at Wu Nan

"You didn't bring back the surveillance video, only a few screenshots, what's that?" Wu Nan smiled slightly,"And, sister, if you can give me the resources of the criminal police team, I might be able to solve the case in minutes!"

Wu Xinyan's eyes widened slightly!
