Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 259 Two Footprints
Lu Chuan's father was in charge of catering logistics in the group.

Donglaishun in Haizhou City was invested and opened by him.

In fact, there was no Donglaishun in Haizhou in the past.

Donglaishun was born because Lu Qiqiang liked it.

It's no wonder Donglaishun's young master has to spend money to eat.

"Master, try this, Donglaishun's traditional mutton, it tastes very fresh."

Lu Chuan still likes this traditional mutton very much.

Fat and thin, the meat is silky and smooth, as thin as a cicada's wing.

The key is that it is not expensive, and it is much more delicious than some so-called fresh-cut lamb and beef.

Dipped in special sesame sauce, the taste is called authentic.

When the weather was cold some time ago, Lu Chuan often brought Forensic Doctor Shen over to eat hot pot.

The food for the two of them was also simple. Three plates of traditional mutton, one plate of spinach, and one plate of mushrooms were enough.

"Chuanzi, here's a plate of this."

Lao Bai is also good at this.

Yang Sen seemed a bit out of place, this guy didn't seem too fond of mutton.

Specifically deal with two plates of beef, say that strength.

"Xiao Lu, Zhang Qi called just now, there is a case, please help me look at it."

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 Brigade over there. He just called. There is a serious injury case. It has been going on for several days, but no one has been found yet."

Serious injury?
"Is the person alive?"

Lao Bai's words almost choked Liu Guodong.

What does it mean that people are not dead?
"The person is not dead, but he is almost in a vegetable state. I heard that he is still lying in the ICU."

"I asked him to send the file over, and I will go back and look at it later."

"OK, no problem."

Lu Chuan readily agreed.

To put it bluntly, Lu Chuanjue himself has no other ability, except that he can help when doing technical appraisal and analysis.

The Haizhou Criminal Investigation Detachment has an hour and a half break at noon.

However, one and a half hours is definitely not enough to eat a hot pot meal. It was already past three o'clock in the afternoon when the four of them came back.

Liu Guodong turned on the computer, and the Criminal Police Brigade of the High-speed Railway New District had sent over the scanned files of the case.

"see this."

Handed the printed dossier to Lu Chuan: "It's not such a serious case."

What Liu Guodong said is correct. Compared with serious injury cases, homicide cases are obviously much more important.

As for the criminal investigation detachment, the general injury cases cannot be sent here at all.

There haven't been many cases recently, and Liu Guodong and Zhang Qi have a good relationship, so they need to help out.

"footprint?"

Liu Guodong nodded.

"When the murderer hit someone, he put a sack on the victim. The case happened in a corn field in the countryside. There is no monitoring equipment nearby. It is not known who did the beating."

"Besides, the victim is still lying in the hospital and has not woken up yet. There is no way to even ask."

"Fortunately, the murderer left relatively clear footprints on the scene at that time. You can help me take a look."

Lu Chuan nodded.

Photos of the footprints are in the dossier.

In fact, the criminal police brigade in the high-speed rail new area also has surveys.

It's just that in terms of ability level, it may be more than one level behind the Criminal Investigation Detachment.

This is mainly due to two reasons.

One is the case taken by the criminal police brigade, which is naturally a major case, but the difficult criminal investigation detachment took over directly.

This has led to the lack of sufficient case experience in most criminal police brigades in terms of training talents, especially technical talents such as field survey and forensic medicine.

On the other hand, there is insufficient talent reserve below. Most of the technical police in the criminal police brigade are transferred from the front-line criminal police.

In the past few years, there have been high-achieving students who have graduated from majors to enrich the grassroots.

But there is a problem here.

The old man has experience, but lacks theory, which affects the improvement of strength.

The rookie has the theory, but lacks experience, and has not gone through enough practical training, so there is no way to improve the strength of the grassroots criminal police brigade in a short period of time.

Therefore, in recent years, the grassroots criminal police brigade has to rely on its superiors in terms of technology.

Of course, even with technology, there are still equipment.

Not to mention the Criminal Police Brigade, even the Haizhou Criminal Investigation Detachment, without the [-] million donated by the Qiangsheng Group, the equipment was also old.

In the dossier, there is a preliminary analysis of the footprints found at the scene of the current survey of the Criminal Police Brigade of the High-speed Railway New Area.

"Male, 1.7 meters to 1.8 meters tall."

It’s over.

This is the footprint result of the investigation and analysis of the grassroots criminal police brigade.

Regarding this, Lu Chuan said... This conclusion may be a bit crude.

"There was an investigation of all the villagers who fit this height in the village, but the murderer was not found."

"Let me take a look first, this footprint... is still interesting."

For one thing, Lu Chuan felt that the current survey by the Criminal Police Brigade of the High-speed Railway New District was still possible.

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, they have to send the footprint model over, or go to the scene to see it, in order to get a relatively accurate analysis result."

Model……

Liu Guodong didn't even need to ask, he definitely didn't.

He had seen Lu Chuan do that thing twice, and the grassroots units might not even know what they used as models.

"Let's go to the scene."

"However, in the past two or three days, I don't know how the site is protected."

"I'll call and ask."

Yep.

Lu Chuan nodded: "It's best to have a scene. If it's just a photo, it's not impossible to analyze it, but there will be some errors."

When Liu Guodong called, Lu Chuan had already started to study this set of footprints.

The shooting of footprint photos is relatively standardized.

There is a ruler next to each footprint, which allows the size of the footprint to be measured.

And the other party used a one-to-one survey and photo method.

The size of the printed picture is actually the same as the size of the footprint itself.

The soles of the feet are broad and thick, about forty yards in size.

From the depth of the indentation at the arch of the foot and the width data of the forefoot, it can basically be determined that it is a man's footprint.

Of course, this is basically probable.

According to footprints, there is a probability of error tolerance in judging men and women.

No matter from the perspective of forensic medicine or current survey, the foot bones cannot determine gender.

But the footprints of men and women, in terms of probability, are quite different.

Male footprints are broad and thick, while female footprints are small and delicate.

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 big toe shoes.

But judging by height...

After careful measurement, Lu Chuan has a very different opinion on the judgment of the Criminal Police Brigade of the High-speed Railway New District.

In addition, in the series of footprints left by the murderer, there are very subtle differences in the depth of the left and right feet.

The pressure marks on the edges are also different.

1.7 meters to 1.8 meters...
