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

Chapter 113 Messy Footprints
Something happened again? !

Lu Chuan, who was still a little confused, was awakened in an instant. At this time, in the case of a homicide, Zhang Hui could still tell what happened. One can imagine what the case was.

Liu Guodong put on his police uniform, completely sleepless: "Another murder?"

Zhang Hui nodded, but his bloodshot eyes were shining brightly: "It's a murder case, and...it's still in Qinghe Amusement Park!"

After 45 minutes, Lu Chuan stood in the same position as yesterday again.

The construction site of Qinghe Amusement Park is about 700 meters east of the main gate, on the edge of the fence near the woods.

Today's sunshine is very bright, but when it shines on the criminal police at the scene, they can't feel the slightest warmth.

The same place where the body was dumped, the same naked body, and the same reporter.

Zhang Fugui's face was pale, and he was a little trembling when facing Zhang Hui's questioning.

"It's just this morning... because of yesterday's incident, my tour time today was a little earlier, and it turned out..."

Yesterday, the cordon Zhang Hui and others pulled up was still there, but there was another corpse in the open space that should have been empty.

Although Zhang Fugui worked as a janitor in the corpse refining room of the funeral parlor, he encountered two cases of dumping corpses in two consecutive days...

"Comrade police...how about sending someone here to watch tonight?"

"Maybe the other party will come back..."

Again?

The corners of Zhang Hui's eyes twitched.

Two dead bodies were found in the same place for two consecutive days. Zhang Hui had never seen or heard of them.

Zhang Hui has seen and participated in the investigation of serial murder cases, but he has never experienced such cases.

Not to mention him, there are quite a few criminal police officers who have worked on the scene for more than [-] years, and they have never heard of such a thing.

The corpse was dumped again at the same place, what did the murderer think, playing black under the lights?
Or provoke the police?

No matter which one it is, Lu Chuan has already started to put on his equipment and conduct site survey.

This time, Wang Changjiang and Shen Yan followed.

The scene has been inspected yesterday, except for one more corpse, nothing has changed.

The place where the murderer dumped the body was basically the same as yesterday. The naked body turned over along the wall, with scrapes on the skin and a little blood on the snow.

The strangle marks on the neck are very obvious, and the victim was also strangled to death.

"Old Wang, you guys should do the autopsy first, and we'll do the on-site survey of the surrounding area."

Liu Guodong led Lu Chuan, looked around at the corpse, and followed the circular radiation method, with one person spiraling outward and the other spiraling inward to start the on-site investigation.

Because a more detailed survey was done yesterday, naturally there is no big harvest.

After collecting the blood on the snow, the two walked around from the main entrance to the outside of the wall.

Here, after yesterday's incident, it was cordoned off.

Now the cordon has been drooping on the ground, obviously damaged.

According to normal logic, the old man who came for a walk nearby should not break the cordon.

Of course, according to the analysis of normal people's behavior, the body has just been found nearby, so no one should come here for a walk.

Therefore, the cordon that was torn off now should be done by the murderer.

"Master, I'll collect footprints and fingerprints first, and see if I can find anything."

Liu Guodong nodded. The murderer threw the body here for the second time, and there would definitely be traces left. In addition, there was no one doing morning exercises to destroy it, so the possibility of collecting footprints was very high.

But for fingerprints, the possibility is relatively small.

The weather is cold now, and most people already wear gloves when they go out, not to mention the murderer who threw the corpse.

When they conducted the site survey yesterday, they found no evidence such as fingerprints.

Lu Chuan surveyed outside the wall yesterday, and had an impression of the ground conditions.

So, the ground changes can now be seen at a glance.

Messy footprints were deeply imprinted in the snow, and there were obvious marks of pedaling hard near the root of the wall.

Taking out the ruler and camera, Lu Chuan began to take pictures.

Soon, a group of messy but clear footprints were extracted.

"According to the direction of the footprints, the other party came from the west, and then returned the same way."

In detail, footprint analysis includes two fields. One is to analyze the basic characteristics of the footprint owner, such as gender, age, height, and weight, based on the shape, size, and depth of the footprints.

Another direction is footstep tracking, also known as footwork tracking, which is a dynamic footstep analysis method.

According to the morphological characteristics and gait characteristics of criminals' footprints, combined with investigation and interviews, the whereabouts of criminals can be ascertained.

Footwork tracing is an empirical science developed from the summary of folk "code tracing" experience. After years of research, it has formed an identification technology based on footwork for personal identification.

Generally speaking, it is difficult to change a person's footprint characteristics and walking patterns.

For example, the outer horoscope, the inner horoscope, and the bow legs and X-shaped legs.

Superb footprint analysis can analyze a person's gender, occupation, figure, habits, age, physical characteristics, etc. from the weight, gait, stride length, virtual edge, pressure, and soil of the footprints.

Among them, the easiest to judge is height and weight.

Generally speaking, the length of the footprint is equal to one-seventh of the height. Of course, this is just a general statement. The specific calculation formula is that the height is equal to the length of the footprint multiplied by 6.876.

The footprints of suspects of different age groups also have characteristics of different age groups.

For example, juvenile criminal suspects have short steps, thin footprints, irregular distances between footprints, small bone joints, a strong sense of overall footprints, and often curved walking routes.

In most cases, young criminal suspects have large footprints, strides are large, the distance between footprints is even, and they walk in a straight line.

Middle-aged criminal suspects have different characteristics. They walk steadily and slowly, and the distance between footprints will be shorter than when they were young.

The strides of the elderly suspects become shorter, the pressure on the heel of the footprint is heavier than that of the sole of the foot, the bone seam becomes wider, and the overall feeling of the footprint becomes sparse, with a feeling of lightness.

At the same time, if the suspect's steps are chaotic and the distance between footprints is uneven, it means that the suspect may be exhausted or injured.

Although the footprints on the snow were messy, the indentations on the heel were deep and the forefoot was shallow, indicating that the suspect had a straight back and a good posture.

Although the murderer threw the body for the second time, although the pressure of handling the case increased sharply, correspondingly, the murderer also left more and more obvious traces.

"Xiao Lu, collect the footprints first, and I will report the direction of the murderer's footprints to Captain Qin, and see if we can do some tracking."

"Okay Master, I'm done collecting, let's conduct another survey of the surrounding area."

After the incident happened yesterday morning, all physical evidence within a radius of one kilometer from the scene was collected.

Now go again, if found, it may be related to the murderer.

For example, if the murderer smoked a cigarette after dumping the body, that would be fine.

This is equivalent to the suspect sending himself into the bureau.

However, contrary to expectations, the murderer obviously did not show such obvious flaws.
