1995, Starting as a Criminal Investigation Expert

Shoe prints were indeed found at the crime scene, and there were quite a few of them.

The footprints were concentrated inside and outside the wall. There were also footprints on the wall, and inside the house, several dusty footprints and half a bloody footprint were extracted.

Two pairs of shoes, one size 41 and the other size 43.

There are two suspects. Judging from the video footage, when they came in, the man who led the way was wearing a mid-length, dark-colored cotton-padded jacket with a turn-down collar; his trousers were not visible.

Then, in winter, the cotton-padded coats are loose, so you can't tell exactly how fat or thin you are, but you're not obviously fat either; you should be of average build.

The person behind was also wearing a cotton-padded jacket. In the black and white video, it looked lighter in color and was also a mid-length style, which seemed to be a common workwear cotton-padded jacket.

His physique was also average.

Let's call the person in front A, and the person behind B.

So, size 41 shoes belong to category A, while size 43 shoes belong to category B.

The faxed shoe prints were black and white molded imprints, along with printed photos of the scene.

The former shows the area of ​​force applied to the surface, while the latter, having been printed and faxed, has limited clarity and makes it difficult to discern the depth of the shoe print.

After studying it, Li Shu felt that the distortion was severe.

To confirm, we need to see the actual casting on site.

We can only focus our attention on the video recording for now.

They sketched and drew, even using clay, trying to recreate the contours of the face.

The key point is that, including the scene where the person jumps off the wall and is in the dark, there are only 17 frames in total.

It's extremely difficult to deduce someone's true appearance from such a limited number of images.

It took almost a whole day to do.

"Director, it's almost time to leave work. Should I go to the cafeteria to get you some food?" Chen Yan hadn't left yet, and seeing that it was almost time to leave, she reminded her.

Li Shu watched the 17 frames repeatedly throughout the day.

The projector image is not clear enough and has a lot of distortion, so I can only watch the monitor.

My eyes are sore from looking at a 17-inch monitor all day.

Upon hearing this, Li Shu shook his head slightly, threw away the clay in his hand, took a few steps back, and looked at the clay head in front of him.

I only had a rough shape; I tried to make the details, but I couldn't.

We can't just make something up out of nothing.

:

Staring at the clay statue, Li Shu pondered silently.

The suspect wore gloves while committing the crime, so he shouldn't have been so careless as to remove them midway and leave fingerprints.

That fingerprint feature is useless.

As for shoe prints, Li Shujing had handled similar cases before and knew very well that shoe prints were merely an auxiliary investigative tool to help portray the suspect.

It can tell you height, weight, and age, but it's really only of limited help.

Then there's na.

The victim resisted, and a detailed on-site investigation report was faxed over. Li Shu reviewed it and found that no other biological samples were collected at the scene.

The autopsy also failed to find any evidence that the suspect was scratched or that a punch broke the suspect's nose, and no biological samples of the suspect were extracted from under the fingernails or from the fist.

The surrounding area was searched, but the small backpack that the suspect took from the scene, or any other abandoned evidence, was not found.

Then there would be no way to obtain biological samples.

Moreover, even if it were true, without a database, there's no way to find the person.

Finally, there's the gun.

The suspect fired a total of eight shots at the scene, and the male homeowner who resisted was shot three times.

Of the remaining five shots, the male homeowner's father, another adult male, was shot twice.

All eight shell casings were left at the scene and were retrieved intact.

There are three types of markings on the bottom of the cartridge cases: two domestic and one from abroad. The quantity is so large that it is impossible to trace the origin.

Li Shu asked Chen Yan to inquire with the Firearms and Ammunition Department. A few days after the incident, the Su'an City Public Security Bureau made rubbings of the firearms and ammunition and sent them to the Second Institute for comparison.

Unfortunately, the database in the institute did not match the data.

That means the route of finding the person through the gun is also blocked.

In this situation, based on Li Shu's experience in handling cases, there is only one scenario that is most likely to bring about a new turning point in the case.

That means the suspect committed another crime and fired a shot again. By comparing the bullets, it was confirmed that it was this group of people.

This is the same situation as Bai Changjun's.

He fled to Yunzhong and hid in a remote coal mine, changing his name and disappearing without a trace.

Only by shooting and killing again would their trail be exposed.

However, this situation often means the emergence of new victims, which is not what Li Shu wants to see.

:

With this in mind, Li Shu decided to go and have a talk with Ji Chunyang.

A family annihilation case, five lives lost, that's a major case.

The ministry should take this seriously.

Li Shu left quickly.

Chen Yan instinctively wanted to chase after him, but stopped at the door and went back to help Li Shu tidy up his drawing board, portraits and other items.

When I arrived at the department, Ji Chunyang was still at get off work.

Seeing Li Shu arrive, he was pleasantly surprised and, while making tea, said, "You're such a busy person, how come you still have time to come here? I heard from Director Yue that you're working on the database and testing for toxic substances in the sewers. That's impressive! How's it going? Is everything going smoothly?"

Li Shu took the teacup and shook his head.

Magnetic solid-phase extraction is doing well; Sun Bomin plans to get involved. But with NA, it's still very far off.

"It's alright, this is cutting-edge technology after all, let's take it one step at a time."

Ji Chunyang sat down and lowered his voice, saying, "Anyway, Director Yue and the others support it. They've held several meetings about this matter for you."

Li Shuxin thought to himself that he would definitely support it now, but if he knew that Li planned to spend tens of millions on research and development, that would be a different story.

Just as they were about to get down to business, Ji Chunyang interrupted, "By the way, there's good news from Yuehai and Hong Kong. The situation of Yang Pinghao and He Zhenqiang has been basically clarified. Except for a few individuals, the remaining gang members have been arrested one after another."

"I reckon the verdict will be delivered very soon, next month. These two groups probably won't have a chance to celebrate the New Year."

We are still in a period of severe crackdown, and once a verdict is reached, the process will proceed quickly.

An appeal is useless; judging by the timeline, it will most likely be enforced before the Spring Festival.

Li Shu's eyes lit up, and he said, "That's indeed good news."

These two groups have committed numerous crimes. Although the main criminal acts took place in Hong Kong, Hong Kong is not their own territory.

Ji Chunyang smiled, then lowered his voice and said, "There's more good news. Do you want to hear it?"

He was being mysterious, so Li Shudao asked, "Don't tell me it's about making meritorious contributions?"

Back in Hong Kong, the institute has already reported the achievement, which is probably because Ji Chunyang got concrete information from the ministry.

"no."

Ji Chunyang shook his head and said, "Given your situation, what does a first-class merit mean?"

Every case that Li Shu solved was a major case, and he was able to earn merit for each one.

:

But Li Shu's contributions don't stop there. In addition to solving cases, Li Shu resolved so many criminal technology issues.

The country has always advocated for revitalizing the nation through science and technology, recognizing science and technology as the primary productive force. In these fields, Li Shu's contributions are the greatest.

Hearing this tone, Li Shu thought to himself, "Wow!"

Ji Chunyang himself doesn't seem to have ever been awarded a first-class merit, only a collective one.

"He can't possibly be a hero or model worker, can he?" Li Shu raised an eyebrow.

I've already received a first-class merit award, but I haven't received a hero award yet.

There are first-class and second-class heroes and role models. The selection process is based on their deeds and achievements, and the selection and public announcement are conducted at any time.

It's an internal matter within the department.

Li Shu knew exactly what kind of deeds and achievements were worthy of being called a hero.

Either they die heroically while carrying out their mission, which is the most common reason.

Another task is to solve major nationwide cases, and one or two cases are not enough.

Based on this criterion, I do qualify for the required level.

This year alone, I've helped solve quite a few major cases.

However, he was a technical police officer and did not rush to the front line.

Another example is his long-term dedication to his arduous post, working tirelessly day after day for ten years.

Finally, there is another category, which includes those who have made significant contributions, such as major security measures or scientific research achievements.

Li Shu is even more qualified for this.

Therefore, after comprehensive evaluation, it would be reasonable for the department to recognize itself as a model worker at the end of the year.

Li Shu mainly felt that he was still too young and had suffered a bit from his age.

"That's not it."

Ji Chunyang shook his head and said, "Of course, you'll definitely be recognized as a model worker. I heard Director Yue mention it, and I reckon he'll give you a surprise at the end of the year."

As for the hero, Ji Chunyang felt it was a sure thing.

After all, Li Shu has helped solve too many major cases and made so many outstanding contributions in the field of technology.

Even if I don't get it this year, it's only a matter of time.

"I was talking about something else," Ji Chunyang said in a low voice. "I heard that the Youth League is planning to establish a May Fourth Youth Medal next year. 'You're the youth,' he said, referring to you."

:

He pointed at Li Shu and said, "Each department can report it to higher authorities. The ministry intends to report you. Although it's a medal from the Youth League Committee and we don't get any real benefits from it, it's still a national medal, and it's the first one ever, so it's very rare."

Being recognized as a hero or model worker, or receiving a first-class merit award—these all bring tangible benefits.

Bonuses, guaranteed admission to police academies for children, early promotions, priority in advancement, and even the level of condolence given upon death are all exceptional.

But that doesn't mean the Youth Medal is useless. After all, it's a national award, and only a few people are selected each year.

It can be featured on the national news program, CCTV.

"Is it accurate?" Li Shu was pleasantly surprised, but he was too embarrassed to show it.

Ji Chunyang, who had been a bureau chief, had a sharp eye for talent. He said, "Alright, don't hold it in. Laugh if you want to. Besides, out of all the people in the system, I've thought you're the most suitable."

Based on Li Shu's work ability and achievements in the field of criminal technology, he truly deserves the title of "young and promising".

Li Shu finally smiled and said, "It's not necessarily true. At most, it's just a nomination. There are so many outstanding young people across the country."

Ji Chunyang laughed heartily before asking Li Shu what business he had with him.

When the conversation turned to business, Li Shu immediately stopped smiling and said in a deep voice, "There's a case I'd like to discuss with you."
