Seeing this, Jiang Si explained, "It's because of the lighting."
"Light?"
"Yes, the weather in Beijing was sunny on the day of the incident."
"When the light is from the side, it will make a person's nose appear longer and their eye sockets appear deeper than usual."
As she spoke, Jiang Si opened the second portrait.
"This is the suspect's view from the old man's perspective. You can clearly see from here that the suspect's nostrils are pointing sideways."
"His columella is not prominent, and the bridge of his nose is not visible, so this person must have a flat nose."
Jiang Si not only knew that this person had a flat nose, but she also made an amazing discovery by calculating the nasofrontal angle and the width of the base of the nostrils.
This person's nasofrontal angle is an astonishing 146 degrees!
Considering the obvious bulge in the lower part of the person's nasal columella, Jiang Si suspected that the person's nasal bridge may have suffered a severe fracture in the past.
There aren't many hospitals in Beijing that can perform this surgery.
If we follow this line of investigation, we should find something.
As for why she deliberately made special adjustments to her nose and lips, Jiang Si also gave her own explanation.
Unless a person has received professional training, they can only remember the most prominent features on other people's faces.
Especially those with bulbous noses and thick lips.
I can remember anyone I've met.
Therefore, exaggerating the proportions appropriately at this time will not only not affect other people's judgment, but will also increase their memorability.
Upon hearing Jiang Si's explanation, Uncle Huo immediately understood.
That's true, let alone strangers.
Even among colleagues at work, if you ask someone what they look like, most people might not be able to tell you.
But if you ask, anyone in the workplace knows who has a flat nose.
Thinking about it this way, Uncle Huo was already starting to get excited.
But to his surprise, Jiang Si had another surprise in store for him!
Jiang Si only learned today that the public security system used a facial features database template in this era.
They were all paper silhouettes, and the variety of combinations was very limited.
Take the eyes for example; there are only four eye shapes in the template.
There are five types of noses.
There are also five types of mouths.
No wonder that on the day of the incident, the two witnesses went to the police station, gave a statement, and then went home.
Because it's pointless to try.
Fortunately, we now have a profile of the suspect, and the police also know that he had undergone nasal surgery.
So as long as this person is still in Beijing, it's only a matter of time before he's caught.
Even if he were shot later, the lives of the ten people who were bullied and killed could never be brought back.
Not to mention how many girls have been indirectly affected by this incident.
In later generations, Jiang Si drew at least eight or ten thousand detailed sketches of facial features, and in this life she practiced for more than ten years.
For her, creating a completely new facial feature template wasn't actually that difficult.
Of course, the reason she wanted to volunteer today was...
On the one hand, the case deeply moved her, and on the other hand, she did have some selfish motives.
Although she hasn't started working yet, Jiang Si has a very clear plan for the future.
First of all, she doesn't plan to take the college entrance examination.
It's 1968 now. By the time the college entrance examination is reinstated, she will be over thirty years old, and it won't be appropriate for her to participate.
Therefore, Jiang Si prefers to take advantage of the next few years to improve her resume, as if she is accumulating points for herself in advance.
That way, when she returns to Beijing, she will have the freedom to choose.
These were just her personal thoughts, and Jiang Si wasn't sure if the public security system would adopt them.
Fortunately, my fourth uncle is family.
Jiang Si had nothing to worry about, so she said whatever came to mind.
Uncle Huo thought he had misheard and it took him a long time to react.
"You mean, you can help us redraw a set of 'facial features' templates?"
Jiang Si hummed in agreement, "I just happened to have some free time recently, so I thought I'd give it a try."
"Once it's drawn, you can take a look at it first, and then decide whether you want to replace it if you like it."
Upon hearing this, Uncle Huo made a definitive decision without hesitation: "No need to try."
He had a strong feeling that he should wait until the template was successfully drawn up before making it widely available.
The speed at which cases are solved will definitely increase significantly in the future.
Actually, they had been thinking about changing the template used by the public security system for a long time.
Take this incident as an example, if there were a good facial feature template library.
On the day of the incident, they were able to determine the suspect's approximate facial features.
Why did it have to drag on until now?
However, the Ministry of Public Security also has its own difficulties.
After all, everyone knows what the situation is like outside.
These people are unwilling, and they can't be forced to.
Now that my niece-in-law is willing to take on the main responsibility, it's a good thing for the country and the people.
If anyone dares to make a fuss about this, the Huo family will be the first to object!
Uncle Huo said, "We all know how skilled you are at painting. Don't worry, I'll submit a report later."
After thinking for a moment, I asked again, "I just don't know how many images your facial feature template will have in the end. If there are a lot, it may need to be bound into a book."
"And as for the price, we need to sit down and have a proper discussion about that too."
price?
Jiang Si was taken aback. She had only been thinking about building up her resume and hadn't really considered this aspect.
"Fourth Uncle, is there still money to be made for this?"
