Advocate for the deceased

Chapter 3 The Man in the Bathtub ([-])

In the silent night, every bit of sound amplified infinitely, making the whole courtyard even more eerie.

A burst of headlights flashed, and there was a sound of braking in the courtyard in the center.

After a while, several staff members pushed the flat cart to send the deceased's body to the autopsy room.

As soon as the body bag was opened, the arms of the deceased were supported.

The fat man was startled, he held up the camera in one hand, and grabbed the clothes on Zhou Hai's back with the other.

"Mother, why is this hand still holding on?"

Zhou Hai did not speak, and together with Liang Honggang removed the body bag and the pajama pants of the deceased.

Because of the hot weather, the deceased had been soaked in the bathtub, and the abdomen of the deceased had changed slightly to yellow-green.

Fortunately, the water poured into the bathtub was not hot water, otherwise the death time of the deceased would be very difficult to determine.

The deceased was only wearing a pair of black silk pajama bottoms, no underwear or socks.

Dressed like this, it means that he should be preparing to rest, or is resting, so only those who are very close can enter the room.

Zhou Hai looked up at the time, the pointer just pointed to 4:15.

The autopsy will be done in a while, and it can be sent for pathological analysis.

Zhou Hai checked the corpse form carefully.

"The rigor reached its peak, and the plaques [1] were all deposited on the buttocks// and the back, which shows that it has not been moved after death.

The time of death is estimated to be around 24 hours.

Except for the knife wound on the chest, there was no trauma on the body surface, and it was suspected that the chest was the only fatal injury. "

As he spoke, Zhou Hai inserted a blunt round probe into the wound of the deceased.

Probing inward along the sinus channel formed by the stab wound, and measuring the depth after pulling it out, the depth of the wound has reached ten centimeters.

"Without any hesitation, the knife directly pierced the heart between the third and fourth ribs.

Rapidly caused cardiac tamponade, so it was fatal.

However, the deceased did not resist the injury at all, which is somewhat puzzling. "

Zhou Hai raised the scalpel, and cut open the chest and abdomen of the deceased with a single stroke from the lower jaw.

The deceased was a person who paid more attention to figure, with extremely thin fat layer and not thick chest wall.

After removing the internal organs by pulling out the tongue, Zhou Hai stripped the deceased's heart and placed it on a tray aside.

The fat man bent over to take a quick photo, and Zhou Hai showed off the stabbed part of his heart.

"The murder weapon used to stab the deceased should be a single-edged knife measuring 1.8cm wide and 8-10cm long.

The knife is extremely thin, with a thickness of no more than 0.1cm. "

The two were lost in thought, a knife like this, really can't think of what kind of knife it is, Zhou Hai then explained to Fatty and Liang Honggang.

"On the outside of the entire heart, this very hard protective film is wrapped.

We call it the pericardium, and this knife directly penetrates the left and right atria.

The knife pierced the atrium, and a large amount of blood gushed out.

But it can't be sprayed, and it still flows into the cardiac tamponade, so the deceased died of cardiac tamponade【2】.

Only when the knife pierces the artery, due to the huge pressure of the artery, a large amount of blood gushes out in a short period of time, will he die from hemorrhagic shock! "

The fat man shook his lips, "It seems that this person died a miserable death!"

Zhou Hai raised his head and glanced at the fat man.

"How do you know he died so badly?"

The fat man shook his head, "I don't want to know.

I just don't understand, it hurts like hell to be stabbed.

Doesn't he cry for help, struggle, resist? "

Zhou Hai gave a rare smile, "Good question!

Trabecula came to take blood for testing. I suspect that this person was taking drugs when he was killed.

So there is no resistance at all, and he is very cooperative with the murderer.

Otherwise, with his height of 186cm and a weight of almost 80kg, it is not something that ordinary women can kill. "

When the fat man got excited, his small eyes widened, and his voice rose an octave instantly.

"female?
Do you know the murderer is a woman? "

Zhou Hai shook his head, "It's suspicion.

When the deceased was carried out of the bathtub, I found two long hairs in the water and brought them back together.

Let's send it for inspection together later, the owner of the hair is either his sex//partner, or the murderer, or someone the murderer wants us to suspect. "

However, seeing such two hairs in such a thoroughly cleaned room gave Zhou Hai a bad feeling.

Zhou Hai cut open the trachea and lungs without pausing, and the absence of drowning liquid meant that the deceased did not die from drowning.

Neither the hyoid bone nor the thyroid cartilage were damaged, which also confirmed Zhou Hai's inference just now.

The esophagus and stomach were continued to be opened, the cardia and pyloric atresia were normal, and no drowning was found.

The chyme in the stomach has relatively fresh green vegetables and orange-red particles.

Zhou Hai picked them up and held them up one by one under the magnifying glass, and carefully observed them with his right eye.

"Dinner was broccoli, shrimp, carrots.

These liquid trabeculae are collected, if my guess is correct, it should be red wine, and then do a poison test.

After a while, ask the yellow team to see if there is a meal order record in the deceased's mobile phone.

The last dinner of the deceased should be a seafood set meal in a star hotel.

Judging by the degree of digestion of the contents of the stomach, the deceased died within an hour after eating, that is to say, he died just after eating.

This romantic dinner became the last meal in my life.

It seems that he was not on guard against the murderer at all, let Captain Huang investigate all the female friends of the deceased. "

Liang Hong just blinked his eyes.

"Brother Hai, how do you know the seafood set meal he ate?
Also, why do you say it's a female friend? "

Zhou Hai rarely touched the corner of his lips easily, but was blocked by the mask.

"Ask me to eat a few times, and I'll tell you."

The fat man raised his eyebrows, "That's a good suggestion!"

Next, Zhou Hai shaved off the dead man's hair according to the procedure, and opened the dead man's skull. No abnormalities were found in the brain tissue.

The back was also dissected, and no subcutaneous abnormalities were found except for the plaques.

In the end, the wounds on the deceased were stitched up carefully.

At least let him maintain his final dignity and let him leave a whole body.

On Xiaoliang's side, several samples had already been sent upstairs for testing.

All three of them took a shower, and it was the hottest June weather, and even after wearing airtight isolation suits for a few hours in the early morning, they were completely soaked.

Put on the short-sleeved police uniform and have breakfast.

Zhou Hai went through the information from the beginning again, the information he knows so far.

At 9:30, Sister Zeng from the pathology department called and the test results came out.

There was indeed red wine in the stomach contents, and ketamine was detected in heart blood and stomach contents.

As for the blood samples sent by Xu Biao, they were found to be from two people.

One is deceased and the other is unknown.

The information database is being compared, but nothing has been found for the time being. Liang Hong just jumped up and down.

"Brother Hai, you are truly amazing!
I'll get the report and notify Captain Huang. "

Xiao Liang said that people had rushed into the center, Zhou Hai raised his head to look at the scorching sun.

"Although DNA samples can be obtained, they can only be used as screening evidence.

I can't find the murder weapon and lack of hard evidence. Now I'm waiting for the hair sample. "

The fat man raised his fist with a smile and punched Zhou Hai on the shoulder.

"That's pretty good, have you tried to recreate the criminal process?"

Zhou Hai nodded, "When Xiao Liang comes down, let's go to Captain Huang and talk about it in detail."

Ten minutes later, the three appeared in the meeting room of the task force.

Everyone in the room was smoking, and with the swing of the air-conditioning fan blades, the smoke was diffused to every corner of the room.

Zhou Hai rubbed his nose, it was difficult to adapt to the special case work meeting of the police, the smell of cigarettes was everywhere here.

Although he also smokes, such a strong smell is really impressive.

However, as soon as they started to work, they kept spinning, without tobacco to support them, wishing they could fall asleep standing up.

Captain Huang introduced the attendees. The director of the Public Security Bureau, senior political and legal officials, and Liu Yong, the deputy director of the Municipal Bureau in charge of criminal investigation, were all present. Zhou Hai nodded to everyone, and led the two of them to sit on the chairs on the east side.

Director Liu looked at the leaders beside him, and pointed at Zhou Hai to roll his name.

"Forensic Doctor Zhou, we just want to hear the investigation opinions of your criminal technology department.

On our side, the investigation has stalled.

The monitoring of the unit building is broken, only the vehicles entering and leaving the entrance of the community are monitored, but the clarity is not high.

Furthermore, Peng Yuhua is a well-known manager in the real estate industry after all.

There is a lot of pressure from all sides, it would be even better if we could reconstruct the crime scene. "

Zhou Hai nodded, and opened a folder on the computer, which was already connected to the projector, and opened the photos of the investigation and autopsy.

The moment he lowered his head, Zhou Hai saw that Xiao Liang used a wallpaper knife to cut off the plastic straps on the outside of the wires.

With a flash in his eyes, he instantly understood the previous question.

"After on-site investigation and autopsy, we have confirmed that the nature of this case is a love homicide."

　[[1] Corpse spots: it is the result of the blood circulation in the cardiovascular system stops after death, and the blood in the cardiovascular system lacks power and accumulates in the lower parts of the corpse along the vascular network.

　　The capillaries and small veins in the lower parts of the corpse are filled with blood, and dark red to dark purple scars appear through the skin. These scars are initially cloudy and strip-like, and finally gradually form flakes, which are corpse spots.

　　[2] Cardiac tamponade: The pericardium is a sac-like structure that wraps around the heart and the roots of the great blood vessels that enter and exit the heart.

　　The pericardial cavity is the space between the parietal pericardium and the visceral pericardium on the surface of the heart.

　　There is a small amount of light yellow fluid in the normal pericardial cavity to lubricate the surface of the heart.

　　Traumatic heart rupture or intrapericardial vascular injury causes blood accumulation in the pericardial cavity, which is called hemopericardium or cardiac tamponade, which is the rapid cause of death from cardiac trauma.

　　Due to the limited elasticity of the pericardium, acute hemopericardium up to 150ml can restrict the return of blood to the heart and the beating of the heart, causing acute circulatory failure and further cardiac arrest.
