On The Day Of My 100th Blind Date, I Arrested My Date: Chapter 75 Find the murder weapon

This kind of smell that makes Chen Yan alert is nothing else.

It was the traces of... stench hidden under the strong smell of blood.

Turning off the olfactory gene lock, Chen Yan frowned.

Stink!

And unlike the smell of the bathroom, this smell...

Chen Yan is more familiar.

In other words, every detective with some seniority will be more familiar with it.

It's the smell of corpse.

Corpse odor is different from other odors. This odor is very special. It is the kind of odor you will never forget once you smell it once.

"When the deceased was found, how long did it take to die?"

"28 hours." Ren Hongfeng replied succinctly: "Judging from the shape, depth and stiffness of the corpse spots, when we found the deceased, it was about 28 hours before the deceased died."

28 hours...

Chen Yan thought secretly.

Any animal, after death, the bacteria in the animal will begin to digest and decompose the body itself after a certain period of time.

Primates, including humans, die, usually an hour later, the corpse gradually becomes rigid, and the bacteria in the stomach and intestines begin to digest and absorb human tissue.

Slowly, over time, the corpse odor will be produced.

Over time, when the decomposition and digestion reaches a certain level, a large amount of gas will be produced inside the corpse, the corpse will applaud, and finally burst open.

Just like the well-known whale explosion.

But for just over a day, according to the room temperature of about 20 degrees in this house, there should be no corpse odor.

In other words, there should not be a corpse odor that is easy to smell.

Of course, when Chen Yan's olfactory gene lock is turned on, the odor sensitivity that can be captured is more than a hundred times that of a normal person.

Carefully observing every part of the scene, Chen Yan simultaneously opened the visual gene lock.

The entire room, like a frame of pictures, zoomed in in front of Chen Yan.

Every tiny detail could not escape Chen Yan's observation.

The blood splattered on the energy-saving lamps on the roof, the dust in the crevices of the corners, and the dig marks left by the deceased who scratched the floor tiles due to severe pain...

At the crime scene, every detail flashed through Chen Yan's mind one by one.

Ren Hongfeng did not disturb Chen Yan.

He had already heard about Chen Yan's rumors.

Wang Shun, the current captain of the detective team in Tieshi, is a classmate of Ren Hongfeng.

Wang Shun was able to be promoted from the original deputy position to the top leader this time, thanks to Chen Yan's help.

Otherwise, it would be nice not to be dismissed if the murder case could not be solved.

According to Wang Shun, Chen Yan is definitely a top-notch expert in on-site investigation.

Very good at spotting details.

He hoped that this time, Chen Yan could still find something.

Turning the screen, Chen Yan came to the place where the deceased was broadcasting live, which was also the bedroom of the deceased.

There is only a computer screen on the computer table, and the host has been taken back by the disk market detective team for inspection.

Behind the table is a double bed.

The whole bedroom space is very warmly decorated, with a pink tone, and some doll decorations are hung on the screen.

The bed surface is very clean, and there is a faint fragrance, and the quilt is flat, it should have just been changed.

"The deceased should have just changed the bedding," Ren Hongfeng, who followed behind Chen Yan, found that Chen Yan was focusing on the bed surface: "The top is very clean, not even the hair of the deceased."

Chen Yan nodded, it was really clean.

The visual gene lock was turned on and nothing suspicious was found.

Turning around and walking out of the bedroom, Chen Yan came to the bathroom.

Since the murderer brutally cut off the facial tissue of the deceased, there is a high probability that it was not unintentional.

The disappeared facial tissue has not been found yet, and it must have been taken away by the other party, at least out of this room.

In doing so, the other party must have a purpose.

However, there is a high probability that the other party will not be able to take away the **** skin.

It is very likely that the skin will be washed in the restroom.

The bathroom in the house is not big.

The washbasin is clean.

"Team Leader Chen," Ren Hongfeng looked at the washbasin: "I personally inspected this washbasin, and the bent pipe below was also opened."

"There is also the kitchen sink, which has also been checked. There is no trace of blood in it. The other party should have never used this sink, nor has the kitchen sink."

Haven't used it?

Have you checked the kitchen sink?

Chen Yan certainly believed in Hongfeng's judgment.

An old detective, who has personally inspected things, generally has no flaws.

Moreover, Ren Hongfeng is very meticulous, and he should have had experience in this area before.

However, the water in the bathroom is not just here.

The sink is just what people are most used to washing their hands.

"Ren team," Chen Yan looked away from the washbasin: "This floor drain... have any of you touched it?"

Floor drain?

Ren Hongfeng shook his head: "The floor drain has never been tested."

Haven't checked?

Since it has not been checked, it means that no one has touched it, but since no one has touched it, why is the surface of the floor drain so smooth?

There are generally three places to drain the toilet.

Sink, toilet and floor drain.

However, after reading the wash basin, Chen Yan did not pay attention to the toilet, but went straight to the floor drain.

As we all know, after a shower, very few people wipe the bathroom clean.

Even if there is, few people wipe the ground, or even the floor drain.

In Chen Yan's eyes, there are traces of water stains and drying up on the wall in the bathroom, as well as on the ground.

This proves that the deceased did not have the habit of cleaning up the walls and floors after the rain.

However, why is the surface of the floor drain smooth?

Chen Yan crouched down, approached the floor drain, and turned on the olfactory gene lock.

really!

A faint smell of blood came from the floor drain!

"Tweezers," Chen Yan carefully took out the metal sheet on the surface of the floor drain and put it into the evidence bag: "Get me a longer tweezers!"

...

After a while.

Ren Hongfeng and Wang Xuan behind him looked at the tweezers in Chen Yan's hands in shock.

On the long tweezers was a scalpel.

The stainless steel blade reflects the light like a ray of cold light.

"This... this..."

Wang Xuan stammered, looking at the scalpel and almost speechless.

Ren Hongfeng's face flushed with excitement!

A scalpel was found in the floor drain of the deceased's house, and it was visible to the naked eye that there was blood in the gap between the scalpel and the handle.

Murder weapon!

This is most likely the weapon used by the murderer!

"Team Leader Chen!" Ren Hongfeng's excited voice was out of tune: "Have you found the murder weapon?"

The detection of homicide ~www.mtlnovel.com~ pays the most attention to the integrity of the evidence chain.

The murder weapon is the most important part of it.

In any device-based homicide case, if the murder weapon cannot be found, it will be very difficult to finalize the case.

And Chen Yan, just a few hours after arriving at the market, when he first surveyed the scene, he found the murder weapon!

Not to mention the problematic surveillance video in the hallway.

This is a major breakthrough in the case.

Chen Yan handed the evidence bag and tweezers to Wang Xuan: "Check the murder weapon immediately!"

Although the possibility of finding the fingerprints of the murderer is relatively small, it is a necessary process to collect traces of the murder weapon.

In the past five days, Ren Hongfeng was under a lot of pressure.

For five days, the case did not progress at all.

However, after just a few hours, Chen Yan found important physical evidence.

Ren Hongfeng is now full of confidence in solving the case!

"Team Leader Chen," Ren Hongfeng gave Chen Yan a thumbs up: "You were awarded honors by the provincial team that day. I couldn't believe it at the time. How could you have won so many honors at such a young age!"

"Now, I'm old enough to obey, you're just..."

buzzing...

While Ren Hongfeng was talking, the phone rang and he wanted to hang up, but Ren Hongfeng subconsciously raised his hand and looked at the caller ID.

It is Wang Jian, deputy captain of the Panshi Detective Squad.

"Team Leader Chen," Ren Hongfeng pointed to the phone: "It's Deputy Captain Wang Jian. He's in charge of checking the people in the building. If you make a call at this time, there may be something new."

Chen Yan nodded and motioned to Ren Hongfeng to answer the phone, don't worry about himself.

"Pharaoh, did you find anything?"

However, when Ren Hongfeng picked up the phone, his expression changed drastically in just a moment!

Hurrying to hang up the phone, Ren Hongfeng's face was solemn, and his voice trembled.

"Team Leader Chen, something happened..."
