Chapter 259 Two Footprints
Lu Chuan’s father is in charge of catering logistics in the group.
He invested in Donglaishun in Haizhou City.
Actually, there was no Donglaishun in Haizhou in the past.
Because Lu Qiqiang liked it, Dong Laishun was created.
It's strange that the young master from Dong Laishun has to spend money when he comes to eat.
"Master, try this, Donglaishun's traditional mutton, it tastes very fresh."
Lu Chuan still likes this traditional mutton very much.
Alternatively fat and thin, the meat is silky and as thin as cicada wings.
The key is that it is not expensive and is much more delicious than some so-called fresh-cut mutton and beef.
Dip it in the special sesame sauce and it tastes authentic.
When the weather was cold some time ago, Lu Chuan often brought Forensic Doctor Shen over to eat hot pot.
The food for two people was simple, three plates of traditional mutton, plus a plate of spinach and a mushroom platter, that was about it.
“Kawako, let’s have a plate of this.”
Lao Bai also likes this.
Yang Sen seems a bit out of place. This guy doesn't seem to be interested in mutton.
Specialize on two plates of beef, talk about its strength.
"Xiao Lu, Zhang Qi just called and asked you to help look at a case."
Zhang Qi?
Lu Chuan picked up a piece of mutton and dipped it in sesame sauce: "From the high-speed rail new area?"
Liu Guodong nodded: "Well, it's the captain of the criminal police team over there. He just called. There is a serious injury case. I have been working on it for several days, but I haven't found the person yet."
Severe injury?
"Isn't the person dead?"
Lao Bai's words almost choked Liu Guodong.
What does it mean that a person is not dead?
"The person is not dead, but he is almost in a vegetative state. I heard that he is still lying in the ICU."
"I asked him to send the file over and I will go back later to help take a look at it."
“Okay, no problem.”
Lu Chuan agreed readily.
To put it bluntly, Lu Chuanjue had no other abilities except that he could help when doing technical appraisal analysis.
Haizhou City Criminal Investigation Detachment has a lunch break of one and a half hours.
However, one and a half hours is certainly not enough time to have a hot pot meal. It was already past three o'clock in the afternoon when the four of us came back.
Liu Guodong turned on his computer and saw that the High Speed Rail New Area Criminal Police Brigade had sent over a scan of the case file.
“Look at this.”
Hand the printed file to Lu Chuan: “It’s not a very serious case.”
Liu Guodong is right. Compared with serious injury cases, homicide cases are obviously much more important.
As for the Criminal Investigation Detachment, ordinary injury cases cannot be sent here at all.
There have been no cases recently, and Liu Guodong and Zhang Qi have a good relationship, so they can help.
“Footprints?”
Liu Guodong nodded.
"When the murderer beat someone, he put a sack on the victim. The crime took place in a rice field in the countryside. There were no surveillance equipment nearby. I don't know who hit him at all."
"And now the victim He's still lying in the hospital and hasn't woken up yet. There's nothing they can do to ask."
"Fortunately, the murderer left relatively clear footprints at the scene. Please help take a look."
Lu Chuan nodded.
The photos of the footprints are in the file.
In fact, the criminal police brigade in the High-Speed Railway New Area also conducts on-the-spot investigations.
But in terms of ability level, it may be more than one level behind the criminal investigation detachment.
This is mainly caused by two reasons.
First, the cases taken over by the Criminal Police Brigade are naturally major and important cases, but the more difficult Criminal Investigation Detachment directly takes over them.
This has resulted in most criminal police brigades lacking sufficient case experience in cultivating talents, especially technical talents such as field investigation and forensic medicine.
On the other hand, there is insufficient talent reserve below. Most of the technical police officers in the criminal police brigade are transferred from front-line criminal police officers.
In the past few years, top students who have graduated from major courses have begun to join the grassroots. But there is a problem here.
The old man has experience, but lacks theory, which affects his ability to improve.
The newcomers have theories, but lack experience and have not received enough practical training. They cannot improve the strength of the grassroots criminal police brigade in a short period of time.
Therefore, in recent years, the grassroots criminal police brigades have to make technical demands from their superiors.
Of course, even if the technology improves, there will still be equipment.
Not to mention the criminal police brigade, it is the Haizhou City Criminal Investigation Detachment. Without the 100 million donated by Qiangsheng Group, the equipment is also old.
The file contains an on-site investigation by the Criminal Police Brigade of the High Speed Rail New Area and a preliminary analysis of the footprints found at the scene.
"Male, height 1.7 to 1.8 meters."
It's over.
This is the result of the footprints analyzed by the grassroots criminal police brigade.
In this regard, Lu Chuan said... This conclusion may be a bit crude.
“All the villagers in the village who match this height were investigated over there, but the murderer was not found.”
“Let me take a look first. This footprint... is somewhat interesting.”
On one point, Lu Chuan felt that the on-site investigation of the High-Speed Railway New Area Criminal Police Brigade was acceptable.
At least the collection of footprints is relatively clear.
But the identification and analysis of footprints cannot be done just by looking at photos.
A footprint model is required.
“Although this photo is relatively clear, we still have to ask them to send the footprint model or go to the site to see it in order to get relatively accurate analysis results.”
Model...
Liu Guodong didn’t even have to ask, there definitely wasn’t one.
He had only seen Lu Chuan make that thing twice, and the grassroots unit didn't even know what it might use to make the model.
“Let’s go to the scene.”
“However, it has been two or three days, and I don’t know how well the scene has been protected.”
"I'll call and ask."
Yeah.
Lu Chuan nodded: "It is best to have a scene. If it is just a photo, it is not impossible to analyze, but there will be some errors."
When Liu Guodong called, Lu Chuan had already begun to study this A set of footprints.
Taking photos of footprints is relatively standard.
There is a ruler next to each footprint so that the size of the footprint can be measured.
And the other party used a one-to-one on-the-spot photography method.
The size of the printed image is actually the same as the size of the footprint itself.
The soles of the feet are broad and about the size of a forty yard.
From the comparison of the depth of the indentation at the arch of the foot and the width of the forefoot, it can basically be determined that it is a man's footprint.
Of course, this is basically a probability.
Based on the footprints, there is a probability of error in judging men and women.
Whether from the perspective of forensic medicine or excavation, foot bones cannot determine gender.
But the footprints of men and women are quite different in terms of probability.
The male footprints are broad and the female footprints are small.
And the styles of men's and women's shoes are also different.
But this does not mean that men cannot wear high heels and women cannot wear large-toe shoes.
But the judgment of height...
After careful measurement, Lu Chuan had a very different view on the judgment of the High Speed Rail New Area Criminal Police Brigade.
In addition, the series of footprints left by the murderer have very subtle differences in the depth of the left and right feet.
The pressure marks on the edges are also different.
One meter seven to one meter eight...
