Chapter 181 A Missing Person Case

Song Junsheng, the head of the fifth group, is an old detective of the fourth detective team of Shen City.

Song Junsheng has been a police officer for 30 years. Although he is only the leader of a group, he is very experienced.

He did not expect that Chen Yan would guess his investigation conclusion just by listening to the comparison of tire marks in his report.

He is indeed a ruthless person who can win the first-class merit.

"Team leader Chen, from the current point of view, we have compared the two tracks in the middle, that is, the tracks of the front and rear wheels of the motorcycle."

"By superimposing two people in the driver's seat and riding separately in the front and back, we compared the depth of the tracks."

"Preliminary inference... There are probably two people who dumped the body."

Two people!

Song Junsheng paused: "Of course, this is just a simulation speculation."

"After all, we did not find obvious footprints at the scene, so it is difficult to make an accurate judgment."

Any simulation can only be said to have a greater possibility of restoring some of the conditions at the time.

But to say that it is certain and certain, it would be a bit too much.

Moreover, as the old detective said, the other party did not leave footprints at the scene.

According to the on-site investigation, the other party used a broom or a branch to clean up the footprints.

As for the tire marks, the other party did not clean them because they were far away from the cement road.

On the one hand, it may be because of the lack of time, and on the other hand, it may be because it is just a tire mark and will not leave any clues.

"Can the source of the tire be found?"

Song Junsheng shook his head: "It's difficult. We checked this kind of car mark. It is an ordinary motorcycle with a very large sales volume in Shen City."

"Of course, because of the tire marks, every car, even if the brand is the same, has different degrees of tire wear."

"Through this, it is possible to find the motorcycle, but it will take a long time."

Chen Yan nodded, Song Junsheng was right.

Car marks, any car, due to the mileage and road sections, the car marks are unique.

However, if you want to find it, you have to spend some effort.

"Is the direction of the motorcycle determined?"

Chen Yan asked again.

According to the direction of the vehicle's tread and the direction of the dirt when the tires gripped the ground, it is possible to infer which direction the motorcycle came from and which direction it was going.

Sure enough, Song Junsheng nodded: "This has been confirmed."

"We analyzed the tire marks of the motorcycle at the intersection of the cement road and the dirt road. The motorcycle came from the east, dumped the body after getting off the road, and then drove west after getting on the road again."

"In other words, the other party did not return the same way?"

Song Junsheng nodded again: "The situation at the scene is basically like this."

The clues of the tires...

Basically interrupted.

But it is not without any gains.

At least, it is now preliminarily determined that there are most likely two people who dumped the body.

This is a major breakthrough.

After a moment of silence, Chen Yan looked at Song Junsheng: "Team Leader Song, the comparison of vehicle traces must continue."

"The pond contracted by Wang Fugui was developed by Tianyuan Village only last year."

"Moreover, the geographical location is remote, and non-locals should not know the existence of this pond."

"Therefore, the murderer is likely to be a resident of the surrounding village."

"Although the work of checking motorcycles is tedious, we still have to do our best to carry it out."

Song Junsheng nodded. This work is indeed complicated and tedious.

Motorcycles are very common in rural areas in the suburbs of Shen City.

Basically every family has one.

And there are only two or three best-selling brands.

According to the results of the on-site investigation, the motorcycle ridden by the murderer is the best-selling type.

Conservatively estimated, there are about a thousand similar motorcycles in the three or five nearby villages.

Less than two hours after Song Junsheng left, the news from the fourth group came.

Thorn strips!

The thorn strips in the body of the deceased are only found in the nearby Fenghuang Village.

The head of the second group, Zhang Yifang, was excited: "Team Leader Chen, our group visited villagers from several nearby villages."

"This kind of thorn strips can only be found on Fenghuang Mountain in Fenghuang Village near the scene."

Fenghuang Mountain?

"What is Fenghuang Mountain?"

Zhang Yifang opened the map on his mobile phone and linked to the projection: "This so-called Fenghuang Mountain is actually a big mound of earth."

"It is in the south of Fenghuang Village. The surrounding land is barren and few people usually go there."

"But although this mound is not high, it covers a large area."

"Look," Zhang Yifang gestured on the map: "This range is Fenghuang Mountain."

"This kind of thorn strips grow a lot on Fenghuang Mountain, and there are no other places."

Fenghuang Mountain...

On the map, there are two cement roads around Fenghuang Mountain.

One goes east and the other goes north.

Connecting Fenghuang Village and the surrounding neighboring villages.

"How far is this place from the pond where the body was dumped?"

"Team Leader Chen, from the foot of the mountain, this road to the east extends all the way to Fenghuang Village, about three kilometers away."

"From Fenghuang Village, about ten kilometers further east, is the pond where the body was dumped."

Ten kilometers...

This distance is not close.

From the map, there are two natural villages in the middle of the ten-kilometer distance.

If the murderer killed someone in Fenghuang Village and dumped the body in Tianyuan Village, he would have to pass through these two villages in the middle.

Generally speaking, in rural areas, people are more familiar with their own villages.

Once out of this range, in fact, you will not have a special understanding of the surrounding terrain.

Unless this person usually goes out a lot and is familiar with the surrounding villages, this is possible.

"Team leader Zhang, notify Song Junsheng of the fifth team that the investigation of the motorcycle will start from Fenghuang Village."

The same reason.

If the murderer is not familiar with Fenghuang Village, how can he have the thorns unique to Fenghuang Mountain?

At this time, Zhao Haiyang, the captain of the fourth team, walked into the meeting room.

"Team leader Chen, the autopsy results are out."

...

On the projection screen, it was the autopsy report.

"The deceased, the exact time of death, was between 2 and 2:30 in the morning of the 10th."

"Based on the degree of wear of the deceased's teeth, the age was no more than 30 years old, and should be around 28 years old."

"The fatal injury was the thorns in the deceased's body, and the cause of death was excessive bleeding."

Chen Yan nodded. Sure enough, although the deceased had been soaked in the pool water, he was pale and swollen.

However, when Chen Yan examined it at the time, he found that the capillaries under the skin of the deceased were very light in color, which was a manifestation of too little blood in the body.

"Based on the degree of immersion of the body, the deceased was immersed in the water for about 6 and a half hours, so the body was dumped at 10:30 pm on the 10th."

"The key point is that when we examined the body, we found some clay deep in the deceased's mouth."

"However, since the deceased was already dead when the body was dumped in the pond."

"At this time, the muscles in the deceased's throat were closed, and generally no debris would enter."

"In addition, the technical department compared the soil in the pond and determined that the clay in the deceased's mouth was not the soil at the dumping site."

"And here," Zhao Haiyang continued to introduce: "Some of the wounds on the face of the deceased were cut before the death of the deceased, such as the nose."

"Some of them were cut after death."

"Judging from the knife marks on the wounds, it should be the same wallpaper knife."

"But..."

Zhao Haiyang enlarged the photo of the deceased's face: "These wounds, the scratches before death, are all from top to bottom."

"The scratches after death, the starting position of the knife, are all from bottom to top."

"And the depth of the knife marks is inconsistent..."

Zhao Haiyang introduced while Chen Yan thought.

Judging from the conclusion of the autopsy, the process of the murder by the other party seemed to slowly appear in Chen Yan's mind.

The other party used thorns to slowly end the life of the deceased.

At the same time, the deceased was physically tortured.

After the other party was killed, he seemed to be still unsatisfied during the transportation and disposal of the body.

The second person who dumped the body, sitting on the back seat of the motorcycle, continued to cut the face of the deceased with a wallpaper knife.

What kind of deep hatred made the murderer so cruel?

"What are the specific details of the whip marks on the deceased's body?"

"This is it. According to the inspection, the latest whip marks on the deceased's body should be left three to five days ago."

"The oldest marks are probably two or three years ago."

About an hour later, the autopsy report was completed.

Chen Yan began to arrange the work: "The clay in the mouth of the deceased is likely to be the clay from the first crime scene."

"Notify the second team leader Zhang Yifang to collect soil from Fenghuang Mountain in Fenghuang Village and compare it with the soil in the mouth of the deceased."

Since the thorns in the body of the deceased came from Fenghuang Mountain, then the clay in the mouth of the deceased is also likely to be related to Fenghuang Mountain.

If the comparison results match, then the first place of death of the deceased can basically be locked in Fenghuang Mountain.

Buzz buzz buzz!

The mobile phone on Zhao Haiyang's conference table rang.

……

Finding the phone, Zhao Haiyang looked at Chen Yan.

"Someone reported missing!"
