Super Time Detective

Tuesday, August 2021, 8 at 10:35pm.

The typhoon has completely moved away from Jincheng, taking away the clouds in the sky. After the rain, the sky is clear and the sun is shining.

In the Forensic Laboratory of Jincheng Judicial Police Bureau.

Officer Huang rushed into Ye Huairui's office in a hurry, but only saw Ouyang Tingting sitting in front of the computer, seeming to be busy filling out some form.

"Tingting, where's Forensic Ye?"

Officer Huang asked.

Ouyang Tingting turned around, smiled politely at Police Officer Huang, and replied:

"Forensic doctor Ye is in the duty room next door, and he said he would take a nap for a while."

The girl said and stood up, "I'll take you there."

They took care of Wang Yan's death scene last night first, and after bringing the body back to the Law Research Institute, they conducted an autopsy non-stop until noon.

After spinning the axis for most of the day, everyone was extremely sleepy.

Zhang Mingming was afraid that he would be too sleepy, so he didn't even dare to drive, so he called an online car-hailing car, and crawled back to his home to catch up on sleep.

And Ye Huairui was still thinking about the police officer Huang who had agreed to come back later, and felt that the sunny day without even a cloud didn't look like it would rain, so he didn't bother at all, and was on duty directly Sleep in the room and pull down.

Ye Huairui originally wanted to let Ouyang Tingting go home, but the girl felt that she was in good spirits. After washing up, she borrowed the policewoman's lounge to take a nap, and then got up to work in good spirits.

Officer Huang actually had a busy day.

While Ye Huairui and the others were busy conducting the autopsy, the police officers were also busy visiting and investigating near Wang Yan's home.

It's a pity that after a long time, the harvest was not as he expected, which made Police Officer Huang eagerly hope to hear some good news from Ye Huairui.

Ye Huairui felt as if he had just fallen asleep, and before he had time to relax his tired brain, he was awakened by Officer Huang's forceful knock on the door.

He got out of the bed, rubbed his temples with his hands, and lamented that he was really old and couldn't compare to the past.

When he was still studying in school, he was very nervous about his studies. He often stayed up all night studying K at the end of the semester, and he was still able to take the exam in good spirits the next day.

Now he just stayed up all night, and he felt as if his soul was going to be pulled out, his feet felt like they were on cotton, and he was floating when he walked.

Ye Huairui opened the door, looked at Police Officer Huang who was also tired and had dark circles under his eyes, and smiled helplessly, "Let's talk in the office."

So the three of them moved from the duty room back to Ye Huairui's office and sat down at the table.

Ye Huairui took out a stack of A4 papers from the drawer and put them in front of Police Officer Huang.

This is the first draft of Wang Yan's autopsy report, the one that has not been signed and reviewed.

"Let's just come to the conclusion."

Ye Huairui has always been used to speaking straight to the point, and he doesn't play tricks with Officer Huang.

"The autopsy results showed that Wang Yan did die of mechanical asphyxiation."

Officer Huang nodded.

The answer was within his expectations.

"The key is, is this mechanical suffocation a suicide or a homicide!"

Officer Huang asked:

"Or to put it another way, tell me, how did the murderer make Wang Yan look like he hanged himself?"

"About this..."

Ye Huairui sighed softly:

"I do not know either."

"what!?"

Officer Huang almost jumped out of his chair when he heard that:

"Did you find nothing!?"

Police officer Huang almost immediately thought of the "suspected" shooting case of a 14-year-old boy last month. At that time, he also sent the body in with great anticipation, hoping that the forensic doctors could give him a reliable and exact cause of death. After the end, they only came to the conclusion of "sudden death", which really troubled them and the police.

"There are many reasons for mechanical suffocation, but it seems that Wang Yan was indeed hanged to death."

Although Ye Huairui found a flaw in Wang Yan's feet and felt that the deceased was most likely a homicide, but in the autopsy, he still sought truth from facts and told Officer Huang his conclusion.

It is also the most common mechanical suffocation, but the significance of hanging and strangulation to the facts of the case is often the fundamental difference between "suicide" and "homicide".

The location of the cord groove of constriction is generally between the hyoid bone and the thyroid cartilage, the direction of force is horizontal, and the two sides are obliquely upward.

Because the hoop has to be put into the head, it is usually made relatively large, so that the rope will form a lift behind the head, and the rope marks on the neck will not be a complete circle, which is called "the rope groove is not locked".

The strangled cord grooves are usually in or below the thyroid cartilage, which is what we usually call the "Adam's apple".

In addition to the problem of the force difference between the two methods, the strangled groove has the deepest traces at the front of the neck, and gradually becomes shallower on both sides, and disappears completely at the lift. However, the strangled groove has a uniform depth throughout the entire circle, and you can see The impression left when a knot is twisted tight.

In addition to the superficial scars, Ye Huairui and the others also checked the inside of Wang Yan's body.

Wang Yan fractured the upper corner of the thyroid cartilage, rather than the transverse fractures of the thyroid cartilage and cricoid cartilage that are common in strangulation, which is also consistent with the change of hanging.

It's just that Wang Yan's body is not without doubt.

The face of the deceased was bruised and swollen, and punctate or flaky bleeding points could be seen on the eyelids. Blood stasis and bleeding foci could also be seen in the brain tissue and meninges. longer.

What is even more suspicious is that the groove on Wang Yan's neck is deep and obvious, and there are traces of friction and bleeding inside, and there are scratch marks on her healthy right hand-this is evidence that she had struggled before her death.

Generally speaking, hanging the neck is a relatively simple way to die.

If the position of the noose is right, even within a minute, the hanged person will quickly lose consciousness due to the obstruction of blood supply to the brain caused by the compression of the blood vessels in the neck.

Although the death by hanging mostly occurs within 10 to [-] minutes after hanging, and there are even cases where people can be revived by hanging for more than half an hour, because the hanged person usually falls into a coma very quickly, it is generally not How many traces of struggle will be left, and the signs of suffocation on the face and blood stasis on the brain will be relatively less obvious.

But Ye Huairui and the others failed to detect the DNA of the suspicious person in Wang Yan's nails, and the scene was too damaged to collect hair, saliva spots or other biological traces.

In the final analysis, if forensic doctors can't explain how to forge the typical gutter around the neck of the deceased, it will be difficult for the police to treat Wang Yan's death as a homicide.

"Hey forensic doctor Ye, I have an idea! Tell me, is it possible that the murderer killed Wang Yan or knocked him out first, and then hung him up?"

Officer Huang guessed:

"For example, cover the person with a handkerchief or something to pass out!"

"It's hard."

Before Ye Huairui opened his mouth, Ouyang Tingting, who was listening in, denied it:

"After all, it's too easy to leave a hole."

Ye Huairui also nodded.

Of course they also considered such a possibility, so they paid extra attention during the autopsy.

For example, police officer Huang proposed to cover the person unconscious, which is a method of simultaneously compressing and blocking the mouth and nostrils with soft objects, hindering breathing movement and causing coma. Of course, it is not difficult to do when the victim is a thin aunt in her 50s.

But covering your mouth and nose is not without trace.

Forensic doctors can find skin abrasions, bleeding, bruises, nail scratches, etc. in the victim's pressure areas.Abrasions and bruises are often left on the victim's lips, oral mucosa, gums and other places, and some of them can even detect the deceased's own tooth marks on the inner mucosa of the mouth.

Even with towels, handkerchiefs, or clothing, the fibers from the cloth are likely to remain in the nostrils or between the teeth of the deceased...

"Well, this one."

Ye Huairui took out a photo and put it in front of Officer Huang.

It was a partial close-up of the body surface taken by Zhang Mingming.

"There were shallow fingernail scratches on the right side of the deceased's neck. Judging from the angle, it was scratched by Wang Yan himself."

Ye Huairui said:

"Her own skin flakes and blood were also detected under her nails, as well as cotton fibers from the cotton rope that strangled her neck."

He paused: "That is to say, she once scratched her neck when she was strangled."

"Okay, I get it."

Officer Huang sighed:

"That means when she was hung up, she was still awake, right?"

Ye Huairui nodded.

"More than that."

Ouyang Tingting interrupted:

"We did not detect any anesthetics, sleeping pills, muscle relaxants, drugs or other common poisons in Wang Yan's body."

"Ugh!!"

Police officer Huang sighed again, and he collapsed in the chair, looking like he was about to collapse:

"Okay, dead end!!"

It is true that the person died after being hung up. When the neck was hung, Wang Yan was conscious, neither dizzy nor dead, and no trace of drug use could be detected... In this way, the case seems to have indeed fallen into a dead end. It seems that the forensic doctors can't help him anymore.

"How's your situation over there?"

Seeing Police Officer Huang's whole body sluggish, Ye Huairui also felt quite helpless:

"Have you found any suspicious persons?"

Officer Huang shook his head in frustration.

"Oh, this damn typhoon."

The incident happened just when the typhoon was hitting Jincheng, and the rain was pouring so hard that hermaphrodites were seen five meters away, and humans and animals could not be distinguished ten meters away. After nightfall, there were few pedestrians, let alone "witnesses".

A camera was installed at the entrance of No. 26 Meihua Street where Wang Yan lived, but it was just a fake, and it was not even plugged in.

Police officer Huang and the others asked the manager about it, and they said that it was broken long ago, and the property management didn't bother to take care of it. They thought it was enough to pretend to be scary.

Later, they also searched for some shops and residents along the street to adjust the monitoring, but without exception, they were all disturbed by the torrential rain. Even with the infrared night vision mode, the outdoor videos they tuned out seemed to have their own mosaics, and it was impossible to see the traffic. human appearance.
