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

Chapter 125

The forensic doctor of the task force is Zhang Yuanchao's disciple, doctoral student Li Changgeng.

When Lu Chuan did the bone identification and analysis for the first time, Li Changgeng discovered it when he was on duty.

The two have cooperated many times during this period and are already familiar with each other.

"Lu Chuan, will you participate in the autopsy?"

Invite the current surveyor to participate in the autopsy, mainly to investigate the traces on the surface of the corpse.

But this scene, in fact, is no longer necessary.

"Brother Li, the investigation in the room is basically finished, and I will not participate in the examination of the corpse form."

The murderer committed the crime cleanly, killing people as soon as he entered the house, and leaving after killing people, without any contact with the corpse.

The basis for this determination is the footprints in the room.

The footprints of coming in and leaving are very clear.

The trajectory of coming and going is easy to judge.

Li Changgeng nodded, and proceeded to do the autopsy.

The autopsies in these three cases were handled by Li Changgeng.

To be honest, there's really not much to do.

The cause of death of the corpse is clear, the method of death is clear, and the time of death is relatively easy to infer.

With a light touch on the corpse in front of him, Li Changgeng knew that the rigor of the corpse had begun to disappear.

Rigidity is one of the most important bases for judging the time of death of a corpse, especially a corpse that died within a short period of time.

Generally speaking, rigor mortis begins to appear 10 minutes to seven hours after death. The time is not particularly fixed, and it is related to different genders, ages, physical fitness, and obesity levels.

There is a certain pattern and order of rigor in the corpse, such as from top to bottom or bottom to top.

According to the stiffness of different parts of the corpse, the time of death of the corpse can be judged.

In most cases, rigor mortis reaches its peak between 24 hours and 48 hours, and then gradually eases.

After the third day to the seventh day, it will completely disappear, and the order of disappearance is the same as the order of occurrence.

The part that is stiff first is relieved first.

As one of the most obvious early phenomena of corpses, rigor is the most direct basis for forensic doctors to directly judge the time of death of the deceased.

As for why rigor rigor occurs, there is still no unified scientific conclusion.

But most scholars believe that this is related to human muscle, especially the decomposition of adenosine triphosphate.

"The cause of death of the male corpse was slashing with a sharp object in the neck, fracture, and death due to excessive blood loss."

The neck is broken, and the person will die from excessive blood loss before the brain is deprived of oxygen.

In other words, at the moment of being beheaded, a person is conscious.

It's just that because the brain is separated from the body, people can't react at that moment.

Can't do anything except blink eyelids.

"Death time, between 48 hours and 52 hours."

"The cause of death of the female corpse is that the head was chopped off with a sharp weapon, the brain burst, and the brain died."

"Death time, between 48 hours and 52 hours..."

In the autopsy record book, Li Changgeng made notes while checking.

Like the current investigation, the forensic doctor will inspect the corpse at the scene of the crime, from top to bottom, from the outside to the inside, and first check the surface of the corpse.

All inspection items have a prescribed process, and each time an item is completed, fill in or check an item in the record book.

While Li Changgeng was doing the autopsy, Lu Chuan followed the murderer's footsteps to the outside of Wafang.

It's been a very cold January, with a heavy snowfall just a week ago.

But the victim, Zhao Dong, was obviously a diligent farmer, and the yard was cleaned cleanly without snow.

The murderer's footprints can be clearly identified indoors, but they are already unrecognizable outdoors.

The speed of the other party's murder in the room was very fast. When the blood of the deceased flowed to the ground, the murderer had already left.

Therefore, the murderer's footprints were not stained with blood.

All three scenes are like this.

This is the most difficult case that Lu Chuan has experienced since he became a police officer, bar none.

Except for footprints, the other party basically left no traces.

Even, Lu Chuan has conducted trace physical evidence analysis on the traces of the murderer's footprints at the last two scenes.

Of course, it cannot be said that there is no effect at all.

The shoes the murderer wore were new, the most common yellow rubber shoes.

It can be found in any market or supermarket.

As for the soil and dust carried by the soles, there was no specific discovery.

It can be said that with Lu Chuan's current elementary footprint identification and analysis ability, what he can do has reached the limit.

The sky was blue, without wind or clouds.

Lu Chuan stood in the yard and took a deep breath.

The air containing the unique smell of cow dung filled his mouth, making Lu Chuan feel a little sour.

Looking back, in the west wing, five black-and-white cows are leisurely chewing the forage ruminated in their stomachs, their big eyes are round and peaceful.

He didn't have his master killed at all, and he didn't have the consciousness to forage in the future.

Ok?
forage?

Lu Chuan was slightly taken aback.

Zhao Dong has been dead for more than two days, why haven't these cows finished eating the fodder?

Lu Chuan stepped forward quickly, walked to the railing of the cattle pen, and looked at the situation inside.

The hay troughs for the cows have long been empty.

But there was a lot of hay piled up on the ground, and the two cows were lying on the side of the hay pile at this moment, eating and chewing leisurely.

That kind of leisurely, quite a feeling of opening one's mouth for food.

In addition, there are two water tanks made of plastic buckets in the cattle pen.

The semicircular white plastic bucket looks like a large plastic bucket cut in half horizontally to make a sink.

In the two sinks, the water stains were a little cloudy, but there was still about one-third of the water left.

A calf is drinking water.

Of course, to be exact, it should be eating ice, the water has already been frozen into ice piles, and the little cow is chewing.

After observing for a while, Lu Chuan looked at the layout of the courtyard.

Then he put on his gloves again, and opened the unlocked door of the east wing warehouse.

A large pile of forage was neatly stacked, and there were three or four white plastic buckets about one meter high inside.

After a while, Lu Chuan returned to the room.

Sun Zhiyou who reported the case is still being questioned.

Seeing Lu Chuan walking towards him, Chen Kang knew that the other party might have something to do, so he winked. Seeing Lu Chuan nodding, Chen Kang looked at the colleague beside him: "Go ahead and ask."

Outside the room, Chen Kang took the Zhonghua Cigarette that Lu Chuan handed over: "What's wrong, brother, what's the matter?"

Although Lu Chuan is only a current investigation criminal policeman of the Haizhou Criminal Investigation Detachment, his participation in handling the case this time is also a temporary transfer.

But Chen Kang and others had a very good attitude towards Lu Chuan.

Although Lu Chuan is young, his surveying skills are really good.

Having experienced two murder scenes, everyone knows that Lu Chuan is professional in spot surveying.

Not to mention the footprint identification analysis.

Moreover, according to Li Changgeng, Lu Chuan's bone identification analysis is much better than the footprint analysis.

Furthermore... no one would dislike Huazi's companion when they met.

No, the two of them went out to smoke, and a few criminal policemen gathered around them.

Lu Chuan casually took out a new pack of Zhonghua Cigarettes, opened them and distributed them to everyone.

"This case... is tricky."

"No, this bastard is probably a professional, and he is so frightfully quick at what he does."

"Hey, there is no clue left. Killing people is like killing chickens."

Lu Chuan and others are busy, and other criminal police are also busy.

The first group of Yumin Village is a small village, with less than 50 households in total, and there are more than [-] people in the village.

In such a small place, it stands to reason that outsiders would be discovered immediately.

But it didn't.

"It's possible that the murder was done at night. The victim's family is in the middle of the village. It may not be easy for outsiders to find out when they come."

Everyone chatted with each other and started talking.

Chen Kang smoked half a cigarette, listened for a while, and pouted at Lu Chuan: "Xiao Lu, is there something wrong?"

I was questioning the reporter just now, if Lu Chuan was fine, it would be impossible to interrupt him.

"It's not a big deal, Brother Chen. When you ask the reporter, by the way, how do you feed the cows of the victim's family?"
