1995, Starting as a Criminal Investigation Expert

"I don't know."

Li Shu himself was still confused.

Of the three papers, the one with the highest value should be the partition comparison method.

After all, they even helped the academician team from Peking University upgrade their system.

Just the fact that I can get a 5,000 yuan bonus is enough to prove the value of this method.

But it shouldn't warrant the Second Research Institute sending someone over specifically for this purpose.

And what can you do here, just to urge yourself to write a thesis?

Just as Tang Weidong was about to ask for details, Wang Ze'an, who was talking to Xu Qiang, exclaimed in surprise, "The series of robberies in Yuehai has been solved?"

Xu Qiang paused for a moment, nodded, and asked Wang Ze'an if he knew about the case.

"Of course I know."

Wang Zean explained, "In 91, this case was merged and supervised by the Ministry. Our institute also sent a gun and bullet trace expert to Yuehai to provide support."

"I went there with our Director Tan. I was in charge of the on-site trace investigation, but the two suspects were very experienced and did not leave any useful traces."

"Later in 1993, another case occurred, in which hundreds of thousands of dollars were stolen. Yuehai asked us for help again to investigate this Type 56 rifle, but in the end, we got no results."

At this point, he quickly asked who the suspect was.

Xu Qiang was secretly surprised to learn that this case was actually under the supervision of the ministry.

That makes sense.

Five cases in five years, three dead and six injured, with the amount of robbery exceeding two million yuan—none of these are minor cases.

He briefly explained Zheng Cheng's situation.

Wang Ze'an said in a daze, "So he did commit the crime in 94 after all."

Seeing Xu Qiang's confusion, he explained, "Back then, they only committed crimes once a year, so we speculated that after the fifth case in 93, these two would definitely commit another crime in 94, but in the end they didn't."

"We thought they'd stopped, but it turns out this guy committed another family annihilation. Damn, that's several lives lost."

Xu Qiang waved two fingers: "Six in total."

This doesn't even include those who were injured.

Wang Ze'an shook his head slightly, sighing, and asked how he had discovered Zheng Cheng.

Xu Qiang simply pointed at Li Shu and said, "Li Shu, it was he who extracted Zheng Cheng's fingerprints from the soup bowl in last year's family annihilation case, which led to the match with him. And through his Type 56 rifle, we learned that he had committed a crime in Yuehai."

Wang Ze'an gasped sharply.

When we talked on the phone before about vacuum coating technology, Li Shu mentioned that this technology is better at dealing with old, sweaty fingerprints than 502 fuming.

At that time, he knew that Li Shu had helped 803 solve the Jianfeng Hotel case.

Who would have thought that using the same method would also solve this series of robberies in Yuehai.

That's not just one case, but two, which is enough to prove the feasibility of Li Shu's application method.

Seeing Wang Ze'an's surprised expression, Xu Qiang laughed and said, "Don't let his youth fool you, he's incredibly capable! You know about 803, right? And the Jianfeng Hotel case in Matsuura, it was Li Shu who helped extract the fingerprints that solved the case."

Wang Ze'an nodded, thinking to himself, "How could I not know? Li Shu had already mentioned it before."

"That's why I came all this way specifically to ask him for advice, but I never expected..."

Wang Ze'an shook his head slightly, he really didn't expect Li Shu to be so young.

"consult?"

Xu Qiang was taken aback. The Second Research Institute, the pinnacle of criminal technology in the country, had actually traveled all this way to consult Li Shu?

Just as I was about to ask what it meant, the train from Matsuura arrived.

As soon as the carriage door opened, a large group of 11 people got off the train.

He had several leather jackets and carried a bag; his demeanor was clearly extraordinary.

Especially the man in the lead, who was thin and tall, with slightly sparse hair, walked with a swaying gait, exuding a very imposing aura.

There's no need to look further; they must be from Yuehai.

Tang Weidong went to greet him.

"Qian Rui".

The man calmly grasped Tang Weidong's hand.

Then she introduced her entourage with a smile.

A middle-aged man with slightly high cheekbones and sharp eyes is Song Wenjie, the captain of the Criminal Investigation Detachment of Yangcheng City Public Security Bureau.

Guangzhou is the provincial capital, so his position as a branch captain is quite prestigious.

Before anyone could introduce Nanjiang, Qian Rui looked up, spotted Wang Ze'an, and asked in surprise, "Wang Ze'an, what are you doing here?"

Wang Ze'an went to Yuehai twice with him, he remembers.

"I have some official business to attend to."

Wang Ze'an smiled, didn't elaborate, and then congratulated Qian Rui, saying that this series of robberies had finally been solved.

"Yes, it's not easy."

When the case occurred, he was already the deputy director of the Criminal Investigation Department and personally presided over the joint investigation, but ultimately no results were found.

This case, if not a major source of anxiety for him, is certainly not far off.

It's gratifying that the case has been solved.

"By the way, which one is Li Shu?" Qian Rui asked.

He called Xu Qiang to learn about the process of discovering Zheng Cheng, and found out that it was a technical police officer named Li Shu who extracted Zheng Cheng's fingerprints and identified him.

"I'm calling you, why are you hiding?"

Tang Weidong waved to Li Shu with a bright smile, feeling a sense of pride.

My own soldiers!

In an instant, all eyes of the Yuehai group were focused on Li Shu.

"So young."

Qian Rui was slightly surprised, and immediately changed his words, saying, "He is really young and promising, Director Tang. Your Nanjiang is amazing to have such a talent."

These words were clearly meant to be flattering, but unfortunately, they struck a chord with Tang Weidong.

He laughed and said modestly, "No way."

Qian Rui then solemnly grasped Li Shu's hand and said, "Li Shu, on behalf of the Yuehai Public Security Bureau, thank you."

He had stopped smiling and his tone became formal.

Song Wenjie and the others behind him nodded in agreement.

They learned that the Yang Luxiang family annihilation case had also been classified as an old case in Nanjiang.

If it weren't for Li Shu, Zheng Cheng would have remained hidden for who knows how long, and the Yuehai case would have taken even longer to reach a conclusion.

"Director Qian, please don't say that. This is what I should do," Li Shu quickly said.

Fortunately, I had already spoken with Zhang Shenghua from 803, whose rank was even higher than Qian Rui's, so I wasn't too panicked.

They suggested we go directly to the site.

So after leaving the train station, the group headed straight for Baizhuang Village.

First, let's look at the accommodations.

The group examined the items very carefully and asked detailed questions about all the specifics.

After all, they came here not only to understand the case, but also with the mission of arresting Zheng Cheng's accomplices.

Qian Rui and his colleagues agreed with Xu Qiang's assessment of Sun Xiaohui.

At the same time, they also asked Xu Qiang a question about the person who partnered with Zheng Cheng to open the audio-visual store.

"Chief Xu, don't you think the opening and closing times of this video store are rather... interesting?" Qian Rui asked rhetorically.

Xu Qiang immediately frowned.

The partner in the audio-visual store is named Guo Shaobo, and he was also investigated last year.

He is Zheng Chengdong's childhood friend from his hometown village in Linshi.

Secondly, this audio-visual store opened in 90 and closed last August.

Xu Qiang understood Qian Rui's meaning; he wanted to say that this audio-visual store's operation was close in time to Zheng Cheng's crimes over the years.

Therefore, it is very likely that Zheng Cheng's accomplice is Guo Shaobo.

"Actually, I've considered it and suspected this guy, but for the time being, there are no clear clues pointing to him."

Yesterday he arranged for someone to look for this Guo Shaobo.

The man went to Northeast China after the Chinese New Year this year, supposedly to smuggle supplies to Russia.

I interviewed some people around him, and I didn't hear that he had become rich overnight or was spending money extravagantly in the past two years.

If he was an accomplice, he would probably have received a lot of money after 93.

Qian Rui smiled and said, "Actually, there are some clues. For example, someone covered for Zheng Cheng last year. Could we ask the people at that hotel back then? Maybe they still remember who checked in."

Xu Qiang understood immediately and nodded repeatedly.

After visiting the residence, they went to see the scene of Sun Xiaohui's crime.

Li Shu followed behind.

Turning his head, Wang Ze'an came closer.

He came along with us.

Li Shu finally had a moment to ask Wang Ze'an why he had come to Nanjiang.

Wang Ze'an pulled Li Shu a few steps behind.

His expression turned serious, and he said, "There's a case in Anjing with a difficult problem in fingerprint extraction. I came here specifically to ask you for advice."
