1995, Starting as a Criminal Investigation Expert

Early in the morning, Li Shu and Tan Guoxiong entered the municipal bureau building together.

"morning!"

Just as he was about to go upstairs, a young policewoman coming downstairs greeted Li Shu.

Li Shu was stunned for a moment before he realized what was happening and quickly replied with a "Good morning."

The other person nodded, smiled, and left.

After everyone had walked away, Li Shu asked curiously, "Guoxiong, do I know her?"

I've only been working here for a month. Although it helps in solving cases, the city bureau is so big, and there are so many people. Ultimately, only a few of them know me or even know me personally.

Tan Guoxiong thought for a moment and said, "Who knows? Anyway, after yesterday's work meeting, you're practically a celebrity in the bureau now."

Li Shu punched him lightly: "Stop it."

Yesterday, September 21st.

There is still one month until the National Games begin on the 22nd of next month.

The bureau held a work mobilization meeting in the auditorium.

The goal is to do everything possible to ensure safety and security during the National Games.

Meanwhile, after the meeting, Tang Weidong severely criticized the Criminal Investigation Detachment regarding the September 5th case.

The case has been transferred, and Cheng Jianrong has also identified the scene.

Logically, there should be a conclusion by now.

After several days of discussion, the department decided to issue a reprimand.

The case was solved, but the merits and demerits did not offset each other.

Peng Rong and his friends had discussed it privately as well.

Li Shu also thought about it. From Tang Weidong's perspective, if the four burglary cases in the High-tech Zone had been solved in time and the suspects had been caught, the subsequent September 5th incident would not have occurred, resulting in the serious consequences of 3 deaths and 2 injuries.

Therefore, the brigade has to criticize them.

While criticizing the branch, the team also praised Li Shu, who matched fingerprints in the investigation of the 9.5 case, as well as the technical team.

Li Shu, in particular, was commended in a general announcement.

Although no meritorious service was performed, this is still a legitimate award with an honorary certificate, which will be recorded in the individual's file and will be of great help to future promotions and personal development.

The key point is that Li Shu had only been working for one month when he received a commendation in public. Perhaps it was because of this that many people in the bureau remembered Li Shu.

Speaking of this, Li Shu remembered something he had been considering: switching to become a criminal investigator.

Taking advantage of the commendation and the leader's good mood, isn't this a good time to bring up this matter?

Li Shu felt it wouldn't be appropriate to go directly to Tang Weidong.

They skipped several levels.

I was hesitating in the morning when someone called my name.

Looking up, I saw a young man I'd never seen before.

Only after asking did I find out that they were from the procuratorate.

His name is Yu Zhiyong.

"It's like this." Yu Zhiyong took out some documents and handed over a copy of a fingerprint comparison and identification report, saying, "The robbery case of Qiao Suqing from the Tingyang Branch was transferred to us yesterday. After studying it, I have some questions about this fingerprint identification report."

Li Shu sat up straight.

Cao Fangxu has been arrested for several days.

They obtained a confession from him, but the murder weapon, four years later, was still not found.

We've also assessed that the chances of finding it are extremely slim.

Fingerprints are known as the king of evidence and are considered irrefutable proof to a certain extent, so the Tingyang branch chose to transfer them directly.

"Prosecutor Yu, is it not allowed to have Director Liu's signature?" Li Shu asked.

No wonder Han Jianjun wanted to drag Zhang Lu to find him, and even Liu Zhenping really needed someone to vouch for him.

Even though Liu Zhenping has already signed it, the procuratorate still thinks there's a problem.

Yu Zhiyong said, "Li Shu, I'm not saying this identification report is no good. The reason I came here today is to ask you to tell me how you produced this report, or rather, what fingerprint comparison methods you used."

"Since I've never encountered these methods before, when I go to court, won't I need to understand the principles behind them before I can explain them to the judge?"

Upon hearing this, Li Shu secretly breathed a sigh of relief.

I'm worried that the prosecutor's office won't accept this expert report.

If they don't admit it, then this case will be really troublesome.

Cao Fangxu's testimony alone is not enough.

Many people give a good confession in the interrogation room, but then recant their testimony in court.

Li Shu breathed a sigh of relief, but to be certain, he still asked, "Prosecutor Yu, can I understand that you have decided to prosecute Cao Fangxu?"

Li Shu is concerned about the follow-up to this case.

The main problem is that Cao Fangxu caused too much harm to Qiao Suqing.

If he were just a bad guy who simply robbed Qiao Suqing, after four years, he might have just let the matter pass by with a bit of resentment.

However, he was lustful and tried to get close to Qiao Suqing. He took advantage of Qiao Suqing's weakness after she became paralyzed and started a relationship with her.

The key point is that after Qiao Suqing rejected Cao Fangxu's marriage proposal, she felt sorry for Cao Fangxu and took the initiative to offer to compensate him, and then had a relationship with him.

The beast didn't refuse.

After learning the truth, who could bear such a blow?

Li Shu called to ask about it yesterday morning.

Tian Yu said that Qiao Suqing has been hospitalized and is now on a hunger strike, refusing any treatment.

Her father would come to the police station entrance to keep watch whenever he had free time.

On his first day, he carried a kitchen knife in his bag and said directly that he would die together with Cao Fangxu when Cao Fangxu handed him over.

Tian Yu was so frightened that he arranged for someone to follow him at all times.

In this situation, if Cao Fangxu is not sentenced due to insufficient evidence, Li Shuzhen will not be able to accept it.

Yu Zhiyong nodded, probably guessing why Li Shu asked that question, and said, "Li Shu, to be honest, although the fingerprint identification report has Director Liu's signature, the comparison method in it is your own creation. I'm a little worried that if it goes to court, the court might have questions."

"Especially if Cao Fangxu were to recant his testimony, that's why I specifically sought you out to gain a deeper understanding of these methods. I've reviewed this case; this guy is truly a beast. He's caused that young woman so much suffering. It wouldn't be right not to send him to jail."

Li Shu was relieved and immediately opened the appraisal report, asking him what was unclear.

They also took him to the AFIS system and explained the entire identification process to him.

In particular, this partition comparison method, based on the experience of the 9.5 case, can serve as strong supporting evidence.

"Did you also match the fingerprints in the 9.5 case?" Yu Zhiyong asked in surprise.

When he looked at Li Shu again, his expression changed.

That was a big case, and the procuratorate attached great importance to it. It was handled by a team led by a different group.

He only knew that the key evidence was the fingerprints, but he didn't expect that it was Li Shu's identification report.

"If that's the case, then it would be much better."

This proves that Li Shu's method is real and effective.

After gaining a deeper understanding, Yu Zhiyong took his leave.

When he dropped him off downstairs, he hesitated for a moment, then said, "Li Shu, no one has ever done this fingerprint comparison method before. What I mean is, you could compile it into a paper and publish it in some prestigious journals. I think this would benefit both you personally and the case."

If a new forensic identification technique can be published in a core journal, that is a form of recognition.

In extreme cases where other evidence is lacking, the court will only accept it if it is used.

"I'm writing it."

Li Shu wasn't just being polite; he was genuinely writing.

When Zhang Lu went to Ningshan last time, he specifically told Li Shu to write more papers, and he could help recommend him.

For example, it was published in "Criminal Technology," a journal sponsored by the ministry.

If it passes the review and is published, it's equivalent to official endorsement and authoritative recognition.

For Li Shu himself, this is also the path he must take to become a criminal investigation expert.

Han Jianjun took it very seriously and didn't schedule much for himself these past two days, allowing himself to focus on writing his thesis.

After seeing Yu Zhiyong off, Li Shu went upstairs and sat down. Not long after, he received a call from upstairs asking him to come upstairs.

Tang Weidong is looking for someone.

Li Shu was struggling with his decision when he realized this was perfect and quickly went upstairs.

When they knocked and entered, they found that there were other people in the office.

Han Jianjun and Xu Qiang are both there.

Upon seeing Li Shu, Tang Weidong's smile brightened, and he said, "Good lad, you solved an old case without me saying a word."
