Chapter 282 Crime Scene

"Yesterday morning, Zhang Jiantao and I entered this village in the city at 8:30 in the morning."

In the car, Liu Qingshan solemnly introduced the details of the two entering the village in the city.

"Three days ago, the important members of the trafficking gang we have been looking for are likely in this village in the city."

"In order to save time and reduce the target, Jiantao and I disguised ourselves and entered the village in the city to inquire about the situation separately."

"We agreed to meet at a noodle restaurant at the main entrance of the village at 12 noon."

"I waited until 12:10 and didn't see Zhang Jiantao, so I called him, but the prompt was turned off."

Wang Shun on the side took over: "Captain Liu called me at 12:13."

"At that time, we all realized that something might have happened. At 1 o'clock yesterday, 14 search teams began to enter the city to look for Zhang Jiantao's whereabouts."

"At 4:32 this morning, one of the teams found Zhang Jiantao in a sewer in the village."

Chen Yan listened to the reports of Wang Shun and Liu Qingshan while checking the information of this village in the city.

Songjia Village is the name of this village in the city.

In the early years, because most of the people living in the village were surnamed Song, it was named Songjia Village. It is one of the three largest villages in the city in Tieshi.

There are nearly 10,000 households, 30,000 permanent residents, and almost 50,000 migrant workers and workers who rent here.

Songjia Village has existed for a long time, with a history of about 60 years.

The village has dense buildings and old houses.

Many houses have been added or excavated basements in recent years.

The terrain of the whole village is very complex, and the population is also very mixed.

Of course, it is impossible for Liu Qingshan and Zhang Jiantao to come in and investigate such a large village in the city without any preparation.

The main area they investigated was in the northeast corner of the village in the city.

Song Wenlong, an important member of the trafficking gang they have been looking for recently, lives in that area.

"We came here yesterday not to catch Song Wenlong."

Liu Qingshan lit a cigarette and took a deep puff: "We want to find out the situation of this person in the village base."

"Check whether the trafficking gang has business here."

Putting down the information, Chen Yan leaned back slightly on the chair.

It is unrealistic to want to close off such a large village in the city for investigation.

We can only strike accurately, otherwise if we cause panic, the other party will definitely shrink all their tentacles.

It will be difficult to find the other party at that time.

The harsh sound of tires rubbing against the ground brought Chen Yan back to reality.

"Chen Yan, it's here."

Get off the car, it's a dead end.

The edge has been cordoned off, and four detectives are on guard.

Chen Yan put on gloves and walked quickly into the alley.

A sewer manhole cover has been opened.

"Zhang Jiantao's body was found here at that time."

Before he walked near the manhole cover, the unpleasant stench hit his nose.

This is the sewer for discharging domestic sewage.

Chen Yan had originally wanted to open the olfactory gene lock to see if he could find some clues.

But now it seems that the possibility is very small.

Under the cover of this stench, it will be very difficult to distinguish other smells.

But there is always a glimmer of hope...

Wearing a mask, Chen Yan climbed in along the manhole cover.

The sewers in the urban village are relatively narrow and naturally cannot allow pedestrians to pass through.

Zhang Jiantao, who was found, was thrown in by the murderer after opening the manhole cover.

After Chen Yan went in, Liu Qingshan and Wang Shun naturally could not go in.

Ten minutes later, Chen Yan climbed up.

"How many people went in before I went down?"

"Three people," Liu Qingshan answered very confidently: "No one from the search team that found Zhang Jiantao went down."

"They reported it immediately after they found the body."

"Besides me and Captain Wang, only one detective from the identification team went in."

"Is that detective there?"

"Yes!" Wang Shun turned around: "Old Wen, come here."

A middle-aged detective who had been beside the crowd hurried over: "Captain Wang, you called me."

"Team Leader Chen, this is Wen Jianguo, you met him last time you handled a case."

Chen Yan nodded. Chen Yan had met this Wen Jianguo when he was handling a case in Tieshi last time.

This is the autopsy expert of the Tieshi Detective Team, and he is very experienced.

"Hello, Team Leader Chen!"

"Old Wen, please stop being polite with me. What are the results of your examination?"

"A bit strange!"

"What's strange? Tell me?"

Wen Jianguo pointed to the sewer: "Based on the degree of rigor mortis, Comrade Zhang Jiantao should have been killed at..."

Wen Jianguo looked down at his watch: "About 13 hours ago, which was around 11:30 last night."

"But if he was killed at this time, there shouldn't be livor mortis on Zhang Jiantao's body."

"You know, livor mortis usually appears after 12 hours."

"But, in the sewer, the scars formed by the body due to squeezing the sewer wall and the iron pickpocket are very deep."

"It is possible that they can only form after 24 hours at least."

Chen Yan nodded.

Chen Yan also discovered this doubt.

What Wen Jianguo said was strange, that is, the degree of rigor mortis and the time when the livor mortis formed did not correspond.

Generally speaking, this is impossible.

When this happens, there is generally only one possibility.

That is the change in ambient temperature.

Especially the degree of rigor mortis, which is greatly affected by the change in ambient temperature.

When the temperature around the body is low, the rigor mortis will naturally be faster.

Conversely, if the temperature around the body is high, the degree of hardness of the body will naturally be slower in the same period of time.

The condition of Zhang Jiantao's body shows that the temperature around him must have been relatively high when he died.

Moreover, Chen Yan just opened the olfactory gene lock in the sewer.

Although most of the smells were disturbed by the stench of the sewer, Chen Yan still made a little discovery.

The smell of mugwort.

There was a very faint smell of mugwort on Zhang Jiantao's body.

Of course, just based on this smell of mugwort, it cannot be determined that there must be mugwort where Zhang Jiantao was killed.

However, this at least proves that Zhang Jiantao must have been in an environment with wormwood burning for a long time.

"Brother Wang, focus on checking all baths, acupuncture, massage and other places in the urban village."

"Especially the environment with wormwood incense, focus on checking!"

As for other human smells, Chen Yan really couldn't tell.

The stench in the sewer was so strong that Chen Yan couldn't tell the smell of Wen Jianguo, let alone the murderer.

While Wang Shun was arranging the investigation, Chen Yan and others finally removed Zhang Jiantao's body from the sewer.

"Preliminary judgment," Wen Jianguo examined Zhang Jiantao's body again: "Zhang Jiantao's cause of death was internal bleeding."

"Based on the depth of the corpse spots, he should have been killed around 10 o'clock yesterday morning."

10 o'clock!

In other words, Zhang Jiantao was killed less than two hours after he and Liu Qingshan separated.

Zhang Jiantao was beaten by the other party before he died.

There were bloodstains on his body, which should have been caused by a whip.

There were large bruises on his chest.

The other party should have used pillows, books and other objects to pad his chest, and then hit him with heavy objects.

This kind of injury is difficult to detect if the person being beaten is still alive.

But if he is dead, it will cause large bruises like now.

"The tendons of both feet and hands were cut by a sharp weapon..."

"Wait..." Chen Yan stepped forward and carefully observed Zhang Jiantao's ear hole: "Bring tweezers!"

Gently picking, Wen Jianguo and Liu Qingshan saw Chen Yan took out a cotton plug from Zhang Jiantao's left ear.

Then, a stream of mercury flowed out!

Chen Yan frowned, he had never seen such a situation.

Wen Jianguo and Liu Qingshan on the side suddenly changed their expressions.
