Super Time Detective

Standing outside the door was a young man in his 30s, tall and strong, with a liquid nitrogen bottle in one hand and a portable blood specimen transport box in the other. His movements and demeanor were very relaxed, and there was no difference at all weight of something.

"Hey, Xiao Wang."

Zhang Mingming beside Ye Huairui greeted him:

"How about sending specimens?"

The person who came was none other than the clerk surnamed Wang in the institute.

Worker Wang stepped back two steps to the side, let out the elevator door, and replied with a smile:

"The body on Meihua Street has been sent to the morgue."

"Oh, okay, thanks."

Everyone walked out of the elevator in a file and passed by Wang Yugong. Zhang Mingming also said:

"Working overtime is hard."

Worker Wang said with a smile that you have worked hard, so he carried the heavy liquid nitrogen bottle and specimen transport box into the elevator.

The elevator door slowly closed.

Before closing, Wang Yugong looked at the backs of several people, the smiles on his face disappeared, his eyes were gloomy, as cold as a cold pool.

After working all night, everyone was actually a little tired.

But they were eager to find out the cause of Wang Yan's death, so they went directly to the morgue, transferred Wang Yan's body to the dissecting table, and first performed the autopsy.

"It does look like suicide."

Looking at the thin and petite middle-aged and elderly female corpse on the dissecting table, Police Officer Huang sighed.

He put his gloved fingers against the dead man's chin, lifted it up slightly, exposing the gutter on her neck, and said regretfully:

"It looks like a strangle mark from a hanging neck."

Officer Huang and his partner have been police officers for so long, so they naturally have a lot of forensic knowledge.

The two of them looked at the strangle marks on Wang Yan's neck, and they both concluded that this was a typical feature of hanging, not strangulation or other methods that could be disguised.

At that time, the residents of No. 26 Meihua Street found Wang Yan hanging on the ceiling fan of the air conditioner. Although they called 999 at the first time, before the ambulance and the police arrived, they put her down on their own initiative and did not expect to report to the scene. Leave a photo or something.

Of course, everyone's starting point was to save people, and the police couldn't say anything.

It's just that the enthusiastic crowd really messed up the first scene and caused considerable trouble to the investigation.

Take Wang Yan's corpse for example. The neighbors said that the knot was too tight and they couldn't untie it. In a hurry, they found a pair of scissors and cut the rope in half.

Therefore, the corpse placed in front of Ye Huairui and the others had only half a noose around its neck, and it had been pulled by many people.

Fortunately, the rope around Wang Yan's neck and the knot were still intact.

Stretched around the woman's neck is an eight-strand cotton rope for handmade DIY, with a diameter of about [-] mm. It is wound around a loop that can allow a human head to pass through, and a knot that cannot slide is tied at the end to form a dead loop.

Such a noose is more than enough to hang a weak woman weighing only 43 kilograms.

The rope formed a typical anterior constriction on the woman's neck.

The force of the rope is at the front of the neck, between the thyroid cartilage and the hyoid bone, bypasses the left and right sides of the neck, runs obliquely upwards and backwards, and then passes along the angle of the mandible, crosses the mastoid process through the back of the ears, and is at the center of the headrest. A lift is formed above - that's where the knot is.

Officer Huang made a gesture of "lifting" on the back of his neck.

"Like this."

He made an expression of sticking out his tongue and feigning death, "There will be no more people."

Indeed, not only the noose and gutter around Wang Yan's neck, but other traces on her body also support the conclusion of "death by hanging".

For example, Wang Yan's face was swollen, showing a very frightening purple color, scattered spot-like bleeding could be seen on the conjunctiva, neck and facial skin, saliva flowed from the corners of her mouth, and traces of saliva even wet her chest—these All are typical signs of mechanical asphyxia and hanging.

In fact, seeing such obvious hanged scars, Police Officer Huang already tended in his heart that Wang Yan died by suicide.

But Ye Huairui said that she was murdered, which is very interesting.

"Officer Huang, have you noticed the chair she used to step on?"

Ye Huairui said.

Officer Huang nodded.

Of course, he checked such important physical evidence immediately.

When the neighbors broke into the house, they saw a folding bench overturned at Wang Yan's feet, presumably she used it for stepping on.

However, the scene was very chaotic when the body was discovered, and ordinary people did not have the awareness to protect the scene, and the living room was small and narrow, so a bench that was in the way was naturally thrown aside. No one remembers that there is such a thing.

At that time, Ye Huairui and others collected fingerprints on the chair on the spot.

There were more than a dozen of those fingerprints, including those of Wang Yan himself, and those of two neighbors who entered the scene. Apart from that, there was no suspicious trace belonging to the fourth person.

After the initial fingerprinting, they also brought back the folding chair, which is now in the evidence bag.

"It's because her chair is so clean."

Ye Huairui said:

"There are no footprints on it."

"what?"

Officer Huang was taken aback, then turned his gaze to Wang Yan's feet, "But she...is wearing socks."

Indeed, human feet also have lines formed by bumpy skin.

Palm prints, like finger prints, toe prints, like fingerprints, are unique and can be used as evidence for biometric identification.

If Wang Yan stepped on a chair with bare feet and hanged herself, footprints should naturally be left. When Ye Huairui and the others collect fingerprints, they should also be able to collect fingerprints.

But the problem is that Wang Yan wears a pair of cotton socks on her feet, and the socks are obviously a bit thick, which is the same as wearing gloves. Of course, there will be no paw prints when stepping on a chair.

"But, have you noticed that her socks are too clean?"

Forensic doctor Ye pointed to the feet of the deceased.

"It was stormy outside, and her balcony door was deformed and couldn't be closed tightly at all. The water flowed into the living room along the crack of the door. The living room was wet everywhere, and her floor seemed to have not been properly mopped for a while. After that, it was very dirty..."

As Ye Huairui said, he pulled Wang Yan's trousers with his gloved hand, "Look, there are mud marks on her trousers."

The deceased was wearing a middle-aged and elderly suit, which was hard to tell whether it was casual clothes or home clothes. The clothes were loose and simple in style, densely printed with small black, gray and brown florals.

This kind of design and color itself is very resistant to dirt. If you don't pay attention to it, it is really easy to ignore the dots or flakes of water marks on her trousers.

- Yes, this is indeed wrong!

Wang Yan wore a pair of white socks on her feet. Although they were not brand new, they were cleaned fairly cleanly without any obvious stains. Except for the outside of the heel, there was almost no muddy water.

"The stains and muddy water on her heels were rubbed on the ground when she was untied by the neighbors."

Ye Huairui slightly turned Wang Yan's body to the outside, and exposed the woman's back shoulders to Police Officer Wang and his partner:

"She also had quite a few of these water spots on her shoulders, back and pant legs."

After all, he smiled at Officer Huang:

"However, the soles of her feet are too clean."

"Ah...this..."

Officer Huang hesitated for a moment, but still proposed another possibility:

"Could it be because she was wearing slippers, or because she changed into a new pair of socks in order to groom herself before she died?"

Officer Huang remembered that he did find slippers in Wang Yan's house.

It's just that the shoes had been kicked into the corner by the mob at that time, and there were one here and one here, and no one remembered where they were originally located. Naturally, it was impossible to determine whether the deceased had worn them before his death.

Although the weather in Jincheng is very hot, the streets are full of sandals in summer. Without air conditioning, it is rare to wear slippers and socks at home.But what if Wang Yan had such a habit, or just put on a new pair of socks in order to tidy herself up before she died?

"It's not hard to prove that."

Ye Huairui replied, "Take off her socks and take a look."

After all, he called Ouyang Tingting for help, and carefully took off the deceased's pair of socks.

Officer Huang rubbed his hands anxiously beside him.

"Looks like I guessed right."

As Ye Huairui said, he turned Wang Yan's socks over, unfolded the toes, and showed them to the two police officers.

"These socks were indeed put on by 'someone' for her."

He deliberately added an accent to the word "someone".

The two police officers saw that on the inside of Wang Yan's sock, there was a light gray-black mark on the toe, which seemed to be the mark left by some dirty thing rubbing on it and drying it off without washing it.

Ye Huairui used the tip of the tweezers to scratch the soles of Wang Yan's feet twice, and it was easy to scrape off a layer of fine dirt.

"It's not just here."

While checking her feet, Ye Huairui said to Police Officer Huang:

"The inner sides of her feet have dried mud, especially on the toes and heels. In other words..."

Officer Huang quickly answered:

"Someone put socks on for her!"

Ye Huairui nodded, affirming Officer Huang's speculation.

Most people have had the uncomfortable experience of wearing wet socks, especially when the soles of their feet are full of dirty mud.

What's more, some people have made relevant statistics, and most of the planned suicides will tidy themselves up before implementing the plan, which corresponds to an old Chinese saying, "come clean and leave clean".

Even if Wang Yan wanted to wear a pair of socks for herself before she died, she should at least wash her feet first.

Well, this means that there is probably another person who put socks on Wang Yan's dirty feet.

And this person left the scene before Wang Yan's body was found.

"But……"

Officer Huang touched his chin:

"Why did that person go so far as to put socks on Wang Yan?"
