The suspect, male, is 1.73 meters tall, weighs about 60 kilograms, has O-shaped legs, is hunchbacked, and is between 20 and 25 years old.

Liu Guodong and the three looked at the characteristics of the suspect written by Lu Chuan on the manuscript paper, and looked confused.

Lao Bai picked up the manuscript paper, and the wrinkled lines on his forehead could trap a mosquito: "Xiao Lu...... Not to mention other characteristics, how did you analyze this hunchback? ”

Lao Bai has also been doing the investigation and trace inspection for more than ten years, and he said that the investigation office of the Haizhou Criminal Investigation Detachment was still established by him.

It's just that he is really inferior to Liu Guodong in terms of ability, and he is getting older these years, so he really can't cope with a lot of work.

But being old not only means that you are not physically strong, but also that you are well-informed.

Although Bai Wenhai's skills over the years are not particularly outstanding, he has indeed seen the most cases.

Naturally, I have come into contact with this kind of thing, and I have even seen experts in the province do footprint analysis battles in the early years.

Therefore, it is not surprising that the expert experts analyzed the height and weight of the owner through the footprint.

Although the age is very difficult, it is said that the footprints of different ages will be shown on the footprints due to the changes in the spacing of the bone seams, and many experts can also do it.

As for the leg shape, it is easier to have O-shaped legs and X-shaped legs, which can be judged according to the degree of force on the edge of the footprint.

But what's the deal with the hunchback?

Can this thing also be seen through footprints?

"That's right, because of the curvature of the spine, the center of gravity of the body is different from that of ordinary people, and the center of gravity will lean forward in comparison."

Lu Chuan picked up a photo of shoe prints: "The center of gravity of this group of shoe prints is about one centimeter forward than the center of gravity of ordinary people's shoe prints. ”

"Of course, if the other party happens to bow down when leaving this shoe print, the center of gravity will also move forward, but ......"

Lu Chuan picked up other shoe print photos: "Every shoe print photo is like this, then it can't be explained by bending down." ”

Lu Chuan is a good teacher, although he doesn't know how Lu Chuan measured the center of gravity of the shoe print, but why he can judge the hunchback, Bai Wenhai and the three of them figured it out.

In this regard, Lu Chuan is more suitable to be a teacher than Mr. Jia.

"But that's not enough."

Yang Sen frowned and looked at the suspect's information on the manuscript paper: "I think the purpose of the Song Bureau should be to catch the other party, not just to know the suspect's physical characteristics." ”

Lu Chuan shrugged his shoulders and remembered his advanced task: "This is simple, we can send an internal investigation report according to the physical characteristics of the suspect." ”

"Judging from the other party's modus operandi, it should be a habitual thief, these guys won't stop easily, and there is a high probability that they have been hit."

Liu Guodong nodded: "Xiao Lu's physical characteristics of the suspect are already very detailed, I'll go talk to the action team to see if I can send a report, and if there are similar people who can notify us." ”

Yang Sen and Lao Bai nodded, although it is not a trivial matter to send an internal investigation report, it is not a big matter.

If the grassroots police station wants to issue this investigation notice, it must be reported to the higher authorities for approval.

But if the criminal investigation detachment sends a report, it is much simpler.

Of course, this circular also has a scope, and if it is a national circular, the requirements will be high.

Generally speaking, a national investigation is unlikely without more than serious injuries, and this requires that the suspect's criminal evidence has been basically fixed.

In fact, the police handling cases is different from what ordinary people imagine.

Generally speaking, people generally think that handling a case is just about catching the suspect.

But for the police, catching a suspect is often not the first priority.

The most important thing is to fix the evidence, and then arrest and finally judge.

If the evidence is not fixed, even if the suspect is in front of you and you admit that he is the murderer, you cannot arrest him.

That's why many small thefts are so hard to solve.

It's because it's hard to fix the evidence.

Because theft is not the same as homicide, there will be a corpse, a murder weapon, a scene trace, and most of them will have a special motive for committing the crime.

Theft is different, except for burglary and the like, general theft such as stealing bicycles, and the bicycles are taken away.

Most of them are in public places, and there are no traces at all that will be well preserved.

As for motivation...... Does stealing a car of value count as stealing?

Of course, the scope of this investigation notice issued by Liu Guodong is limited, and it is a police station under the jurisdiction of the Haizhou City Public Security Bureau.

This is equivalent to asking his family to find something, what he can say, if he wants to expand the scope again, Liu Guodong's face will not be good.

The internal investigation notice was issued very quickly, and this kind of investigation did not even need Qin Yong's signature.

Of course, the content written on the investigation is also very simple, just to let the grassroots police station pay attention to the thieves with these physical characteristics.

didn't say that this was the talent who patronized Song Jiangguo's father-in-law's house.

In fact, this guy doesn't know what he stole from.

If he knew, he wouldn't dare if you gave him another 10,000 yuan.

Just like no young lady dares to stand on the street behind the police station, there must be a respect inside.

If you have to try, the consequence will be a small theft, and you will be targeted by the criminal investigation detachment.

Even in the past two years, there are four criminal police officers who are currently investigating and studying how to catch each other.

It was still a little late to get off work, and it was already six o'clock after the bulletin was sent.

However, the good thing is that Lu Chuan's advanced task has been completed by two-thirds.

The profiling of the suspects has been completed and an internal investigation report has been issued.

Next, it's up to us to see if we can catch each other.

Of course, this depends on a bit of luck.

Lu Chuan glanced at it with real eyes, people with similar physical characteristics had not entered the investigation report before, which showed that this guy had not committed anything major before, but now he has it.

"Xiao Lu, are you off work?"

"Xiao Lu, it's been a hard work."

"Lu Chuan, act tomorrow as a group dinner, together!"

……

In the courtyard, basically everyone will greet Lu Chuan.

This is a treatment that Lu Chuan has never had since he worked for half a month.

In fact, when he first went to work, he also caused a little sensation.

After all, he caught a wanted criminal when he first joined the company, and he was also a suspect in a robbery and murder case twenty-eight years ago, and most importantly, he arrested someone at a wedding.

The personal third-class merit is really envied by many people.

However, everyone just looked at it with curiosity and first saw if this person who had just gone to work and did third-class merit had three heads and six arms.

In addition to curiosity, it is also a bit of a feeling that the grapes are sour when you can't eat them.

But now it's different, everyone knows the case of Zhang Wen's murder, and the key is the clue that Lu Chuan discovered.

Not to mention, this guy went to the Huaguang Street Police Station this morning and caught the suspect in last year's robbery and wounding case.

If the wanted criminal caught half a month ago was luck, these two cases are strength.

Of course, this is not the most important thing, Lu Chuan's strength is strong, and it is Lu Chuan's business.

The key is to solve the murder case, everyone is stained with Lu Chuan's light, and there is no need to work overtime.

Even tomorrow, the day after tomorrow, the day after tomorrow, and even the next three or five days, as long as there are no major cases, then everyone can take care of the family more.

For the criminal police, there are two things that they care about the most, merit and vacation.

Meritorious this thing......

Ordinary people don't have to think about it, if there is an advanced individual of the year, a model worker or something, it is all burning high incense.

Third-class merit...... There can be one in three years, second-class merit...... I can see one in ten years.

As for the first-class merit......

Nobody wants it, because in the vast majority of cases, getting a first-class merit means that you are sacrificing.

The holiday is very real, and you can see how cool it is when you look at everyone's tired but smiling faces.

However, there are unforeseen circumstances in the sky, and people have good and bad luck.
