Detective: I, Cao Jianjun, started by arresting my brother-in-law.

The moment Xiao Wang saw Zhao Qian, he was completely stunned and immediately became a bit infatuated.

Who is Zhao Qian?

The entire Changfeng branch probably thought she was a top student from the police academy.

But Cao Jianjun knew that things were getting more and more interesting.

Returning to the case of February 2.13th, according to the information in the case file, there are several reasons why Guan Hongyu was listed as the primary perpetrator in this case.

First, Guan Hongyu had also run a logistics company, and there was some kind of competitive relationship between him and the deceased Wu Zheng.

This was deduced by the Changfeng Detachment based on their investigation.

Second, there was a large amount of evidence at the crime scene, including Hongyu's fingerprints.

Third, there was a witness named An Teng who identified Guan Hongyu as the murderer.

However, Cao Jianjun investigated and found through the national public security system that An Teng did not exist at all.

In other words, someone fabricated a person named Andeng out of thin air and then claimed that Guan Hongyu was the murderer.

This is one of the strange aspects of the 2.13 case.

Not only the entire Changfeng branch, but also the entire Tianjin Port Municipal Public Security Bureau, had no one investigate this matter.

Although Andeng does not exist, Cao Jianjun knows that there is a person named An Ting who is very similar to Andeng.

An Ting's true identity is that of someone from the Nanshan Military Region, which involves a military background.

Most importantly, An Ting and Zhao Qian have some kind of relationship.

Are they lovers? Or siblings?

Cao Jianjun's fate remains unknown.

These are all suspicions, and he still needs to investigate step by step.

In any case, the important characters of "Day and Night" have finally made their appearance, and Cao Jianjun feels that some plans can begin.

"I found it!"

Just as Cao Jianjun leaned back in his chair, rubbing his chin with one hand, lost in thought.

Cheers erupted from the crowd who were reviewing the case files, and Zhou Xun, Zhao Xincheng, and others quickly rushed forward.

"Captain Cao, come here, take a look..."

Holding an old case file, Zhou Xun said, "The deceased was Lü Siping, who was murdered four years ago."

"Look, this was filmed at the hotel. The entire scene, except for the body, has been cleaned up very thoroughly."

"Only Lü Siping's body was particularly filthy, as if the murderer had deliberately tortured him."

"Compared to the killer's subsequent modus operandi, he would arrange all the bodies neatly..."

"Only this man named Lü Siping, after being killed, had a body that looked like it had been defiled."

Following Zhou Xun's voice, everyone began to gather around the case and discuss it.

"Captain Cao, this should be the first case of the 'car sex killer,' right?"

Zhao Xincheng looked at Cao Jianjun questioningly: "If this is the first case, why did the murderer dispose of the body this way?"

"Hatred!"

Without hesitation, Cao Jianjun said, "Because the murderer had a grudge against the deceased, he wanted nothing more than to tear the body to pieces to vent his anger."

"If this is the first case, the murderer must have been insulted by the victim beforehand, causing him great psychological trauma."

"Therefore, I suggest... we start the investigation by examining the network of relationships of the deceased, Lü Siping."

"In addition, I have just learned an important piece of information..."

After analyzing the available information, Cao Jianjun changed the subject and took out his mobile phone.

He didn't want to drag this case out any longer, so he wanted to close it as soon as possible.

then.

Cao Jianjun pulled up the comments from the online forum he found on his phone.

This post on the forum was from several years ago, and it happened to be about someone impersonating a security guard and catching someone having sex in a car.

As he spoke, Cao Jianjun pointed to his phone.

"Wang Zhige of the Forensic Science Center had an affair with a female classmate in the wild many years ago because his wife was pregnant."

"Unfortunately, when the two were having sex, someone impersonating a member of the joint defense team caught them in the act."

"After that, Wang Zhige was also extorted for a lot of money and a watch."

"When you're conducting your field investigations, inquire about Lü Siping's network of connections and get information from his friends..."

"Look back four years ago, did Lü Siping do anything like this?"

"If so, it means that the person who caught Wang Zhige in adultery back then was none other than Lü Siping. And the murderer who killed Lü Siping..."

At this point, the case is basically clear.

For a while.

The huge task force headquarters was completely silent.

Everyone stared at each other in stunned silence for a moment, and then they all looked at Cao Jianjun with the eyes of someone looking at a monster.

What do you mean?

The murder case involving sex in a car was discovered in the morning, before it was even dark, and Cao Jianjun had already revealed all the clues.

Next, we need to investigate and eliminate 240. Once we determine the feud between Lü Siping and Wang Zhige, he will undoubtedly be the murderer.

This means that Cao Jianjun has solved another long-standing serial murder case within just a few hours.

Gollum—

Guan Hongfeng and Han Bin subconsciously swallowed.

Zhou Xun almost held his breath, pushing Xiao Wang and the others, and said urgently, "Hurry up, what the hell are you standing there for?"

"You! You... and you, all of you hurry up and get moving, go and investigate Lü Siping's network of connections before his death."

"Quickly..."

In an instant, the task force, which had only been established for a day, was thrown into a frenzy of chaos.

Han Bin and Guan Hongfeng, who play advisory roles, don't need to participate in fieldwork; they just sit in the team and wait, just like Cao Jianjun.

Half an hour has passed.

An hour has passed.

An hour and a half later, Zhou Xun returned with a large group of men, and with a few loud crashes, he smashed open the glass door.

Upon entering the room, he slammed the heavy case files onto the table.

He turned around, pointed at Cao Jianjun, and gave him a strong thumbs up.

"Team Leader Cao, you're awesome! Absolutely awesome."

After saying that, Zhou Xun put his hands on his hips and looked at everyone, saying, "The case is solved. Lü Siping has a friend named Gao Liang, who was imprisoned a year ago for the crime of provoking trouble."

“We just went to the prison and retrieved this person.”

According to Gao Liang, four years ago, Lü Siping had acted as a member of the joint defense team and caught a couple having sex in a car.

"The man not only gave me a lot of money, but he also gave me a watch."

"This matches the old post Captain Cao just made. We've already sent people to arrest Wang Zhige."

200. Guan Hongfeng could no longer hide it and finally laid his cards on the table. [7 chapters, please subscribe]

Wang Zhige worked at the Tianjin Port Forensic Science Center. He was arrested before it got dark.

Novel discussion group: 7032①⑥220

Once they were taken into the interrogation room, everyone was stunned.

Because there is no direct evidence to prove that Wang Zhige killed someone.

Although Wang Zhige had a motive to kill Lü Siping, and he himself suffered from obsessive-compulsive disorder and germaphobia, this does not prove that he was the murderer in the subsequent series of murders.

The task force was completely dumbfounded.

After several hours of continuous interrogation, and it was almost midnight, they still couldn't produce any strong evidence.

Cao Jianjun yawned and entered the other side of the interrogation room.

Through the one-way glass, he pointed to Wang Zhige, who was sitting in the iron chair in the interrogation room.

"Captain Cao, what's this?"

Zhou Xun was somewhat confused: "What do you mean?"

"Did you see the ring on his hand?"

Cao Jianjun said a few words in a calm tone, and immediately, everyone in the room gasped in surprise.

"Holy crap! Captain Cao, you're amazing..."
