traces of all things

Although Tian Ziyao and Geng Zhizhong had greeted each other beforehand, the tragedy of the scene was beyond Lu Zheng's imagination.

This family probably placed the old couple's bedroom on the first floor for the convenience of the elderly.In the bedroom, the corpses of the old couple of the Gong family lay side by side on the bed. Their necks were cut open with a sharp instrument. The pillows and bedding were covered in blood, especially the pillows, which were almost soaked. There were still some blood splatters on the walls. Even without turning over, the old lady's tourmaline bracelet and a pair of gold earrings were still on the bedside table.The murderer didn't seem to be here for money.

On the bedside of the old couple's bedroom, Lu Zheng keenly found a suspicious mark, as if it had been rubbed by something, it was light brown in color, the size of two or three palms, he first called Wei Xiongfeng to wipe the mark I took photos to collect evidence, and then took out a cotton swab and evidence bag to wipe off a stain, and was going to wait for the laboratory for an inspection.

Apart from the bedrooms, the living room and dining room on the first floor basically don't have much special features.What makes Lu Zheng most regretful is that it is so smooth and smooth, the snow-white tile floor, which can be called a footprint and fingerprint collector, is actually quite clean, and the expected bloody footprints did not appear at all.

Soon, the two checked into the kitchen.Lu Zheng first found a few light red marks in the kitchen sink, which looked a bit like blood, and then his eyes were attracted by a mop in the corner of the kitchen.

This mop is a relatively small absorbent mop, which is in the shape of a "T" as a whole. There is an absorbent sponge on the mop head, and there is a handle on the rod. The water in the sponge can be squeezed out by pulling it up. In general households, it is often used to clean stagnant water in toilets and the like.

Lu Zheng stared at the mop, no matter how he looked at it, he felt that it was a bit inconsistent, so he immediately squatted down and turned the mop head over to have a look.

Sure enough, the color of the mop head was reddish brown, and there was a strip of stains on the lowermost position.

Lu Zheng was stunned, and after taking the photo, he cut a small piece of sponge from the mop head with small scissors and put it away.He took out a bottle of luminol from the survey box and sprayed it in the kitchen corridor and other places.

Wei Xiongfeng drew the curtains cleverly on the side.

A terrifying scene appeared. The whole kitchen, corridor, dining room, and even the old couple's bedroom were extended, and the entire ground was covered with blue fluorescent light.

"My God." Wei Xiongfeng was taken aback: "So much blood?"

Lu Zheng shook his head: "It was the bloody footprints and other bloodstains on the ground. The murderer cleaned up the scene after committing the crime. Luminol is more sensitive, and it can react to blood diluted a thousand times. The murderer should have sprinkled water on the ground Dilute the blood, then use this mop to suck up the blood, and finally screw it into the kitchen sink. In this way, the fluorescent light will appear to be full of blood."

After surveying the entire first floor, Lu Zheng went to the gate and called Tang Shaoyuan in, and took Wei Xiongfeng up to the second floor to continue.

Compared with the first floor, the scene on the second floor is even more unbearable.

The floor of the master bedroom was covered with traces of cleaning, and the wood joints of the floor were dyed black and brown.

It seems that Zhan Jiahe and Gong Yunlu were also attacked in their sleep. Like the old couple downstairs, their necks were cut open and the bed was soaked in blood.Among them, Gong Yunlu seemed to have struggled a bit. The mattress on her side was messy, the desk lamp on the bedside table fell to the ground, the lampshade was broken, and there was a mobile phone on the ground. Lu Zheng picked it up and saw that the screen was also shattered into spiders. Wang, she herself is even more horrible, her eyes are open, her clothes are not covered, the wound on her neck is very ugly, and there are many wounds on her arms and body.

Zhan Jia and the other side looked very peaceful, and there was no blood on their hair. Lu Zheng looked at the bedside table on his side, and nodded knowingly after seeing a bottle of Valium in the drawer.

The two children's rooms were in the innermost part of the second floor. Lu Zheng stood in front of a door with a very cute collage of "Ming Fei" on it, made some mental preparations, and pushed open the door.

The scenes inside are heart-wrenching.

This little girl's room is quite large, and it looks like the dream of all girls of the same age, with a snow-white princess bed, beautiful gauze curtains, light pink painted walls, and an exquisite dressing table , there are a few photos of Xiao Mingfei's life hanging on the wall. The little girl has short hair, smiles sweetly, and is very handsome.From the details of this room, we can see how much love this little girl has enjoyed.

The small body of the owner of the room was lying on the bed, already stiff, unlike her parents, her throat was not cut, but her whole head was covered with blood, one side of her head was sunken, and she looked very dead. terrible.

Lu Zheng's heart was on fire, and he took a few deep breaths before forcing himself to calm down.

Except for the bed, there is only one place in this room that looks quite abnormal, and that is the glass cabinet in the corner of the bedroom. The door of the cabinet is opened, and the inside is empty. There are many Barbie dolls scattered on the ground in front of the cabinet, and the number is quite considerable.

There was no sign of a fight, but it looked as if someone had roughly tore open the cabinet door and threw the dolls to the ground as if venting their anger.

"What does the murderer think about the doll?" Wei Xiongfeng muttered while taking pictures to collect evidence.

Lu Zheng shook his head, feeling a little puzzled: "Let's put it away for now, and we'll continue later when we come back. I haven't seen the eldest son's room yet."

Compared with his sister, Zhan Mingyuan's room is not so exquisite. One wall is painted sky blue, and there are rows of bookshelves nailed to it. This little boy should love to read.

Lu Zheng glanced at the deceased on the bed. Zhan Mingyuan's death was similar to his sister's. The head was hit hard and the skull was sunken. It looked very cruel.There was blood all over the blue sheets, but unlike Zhan Mingfei, his bed looked a little messy, and there seemed to be some signs of struggle. His eyes were wide open, looking at the sky, and his pupils had already dilated.

Soon, the entire on-site passage was opened. Lu Zheng wrote down some doubts that would take time to examine carefully in his notebook, and called Tang Shaoyuan, who had finished the preliminary autopsy downstairs, to come up.

"The air conditioner has been turned on at night until now. The room temperature is relatively cool, and the body temperature has dropped by 11 degrees Celsius. The two elderly people downstairs died twelve hours ago, which is around 3 o'clock in the morning." Tang Shaoyuan simply told the road Zheng introduced: "The blood loss of the corpse is serious, and the spots on the corpse are light. The tool used to cut the neck is a single-edged sharp instrument, which is probably a household kitchen knife."

"There is a whole set of kitchen knives in the kitchen, nothing is lost." Lu Zheng sighed: "It should be a premeditated murder, Shao Yuan, come up and take a look upstairs."

***

Several people finished inspecting the entire site, and were about to call it a day and go back to do further inspection work, but they heard a commotion downstairs, and it took a while before they returned to silence.

"What's the matter, Captain Tian?" Lu Zheng asked as he took off his gloves as he walked downstairs, and handed Wei Xiongfeng a large evidence bag in his hand to put it back in the car.

"Oh, it's the old lady from this family who just came here." Tian Ziyao rubbed the center of his brows, with a gloomy expression, "It's also Zhan Jiahe's mother, who fainted from crying and had a heart attack, and was taken away by an ambulance just now. The old lady is really unfortunate, the eldest son Zhan Jiashou died in a car accident with his wife and son several years ago, and now the whole family of the second son is gone, leaving only the youngest son."

When Lu Zheng thought of the two small corpses upstairs that had been packed and bagged, his heart felt like a stone was blocked.

He turned around and looked at the stairs leading to the second floor. At this time, the sun had already set, the lights in the room were dim, and the stairs on the second floor were dark, like a huge mouth swallowing life.

Suddenly, as if he had thought of something, he picked up the survey light in his hand and shone it on the corner of the stairs.

***

"There were six people who died. Judging from the contents of the stomach and the body temperature, the time of death was between two in the morning and three in the morning." Tang Shaoyuan put several bloody photos on the projector in a row, facing Lu Zheng and others sitting in the meeting room succinctly described: "In order of age, the first victim, Gong Ziqiang, male, was 73 years old. The cause of death was hemorrhagic shock caused by cutting the carotid artery with a sharp instrument. The victim, Chen Afen, female, was 68 years old. The cause of death was the same as above. The two were found in the bedroom on the first floor. The murder weapon was the same, probably an ordinary household kitchen knife. The murderer had a good psychological quality and did not hesitate to strike, killing him with one blow. There were not many signs of struggle at the scene."

"There are four people who died on the second floor. The third victim, Zhan Jiahe, who died in the master bedroom, was male, 45 years old. The cause of death was hemorrhagic shock caused by cutting the carotid artery with a sharp object. There were no other injuries on his body. Sleeping pills were detected in his body. Components. Victim No. 39, Gong Yunlu, female, [-] years old. Died from hemorrhagic shock, with multiple sharp injuries and soft tissue contusions on her body. There were a lot of damage to the clothes, and the male DNA was not extracted from the vaginal swab, which ruled out the possibility of having sex before death. Judging from the wound flaps, the wounds on the two were caused by the same kitchen knife as the wounds on the two elderly people downstairs of."

"Here's the point—" Tang Shaoyuan clipped a few photos on the projector again: "There are two underage victims. The fifth victim, Zhan Mingyuan, male, was 12 years old. The cause of death was open brain injury."

"The murder weapon was made of iron with a cylindrical part. It is presumed to be a domestic hammer. The sixth victim, Zhan Mingfei, was killed by the same murder weapon, and the cause of death was also an open brain injury. Since there were two kinds of murder weapons at the scene, it is very likely that The number of suspects is two or more."

Several Ninghai criminal police sitting in the conference room frowned for a while, and some of them rubbed their eyes, almost unable to bear to watch the cruel murder scene.

Lu Zheng on the side frowned.An open brain injury is different from a death caused by hemorrhagic shock. Zhan Mingyuan's head was hit violently by a heavy object. It is reasonable to say that he would die on the spot at this level, but he always felt that something was wrong.

"Brother."

Suddenly a soft voice interrupted his thoughts, Lu Zheng looked up, and Tang Shaoyuan was looking at him with slightly lowered eyes, his eyes were very focused: "Any thoughts?"

In an instant, everyone's eyes were on Lu Zheng's face.

"Cough cough." Lu Zheng coughed and organized his words a bit: "When I was surveying the scene, I found that Zhan Mingyuan's bed was covered in blood, which was quite messy, and it was very different from Zhan Mingfei. If we say it is open If the traumatic brain injury resulted in immediate death, what are these signs of struggle?"

The author has something to say:

I saw everyone’s comments yesterday. Some of them were teasing Xiaotang’s magical curly hair. In fact, if you consult the friends around you, you will find that most of them are barometers of humanoid self-propelled hair. Volume and air humidity are positively correlated...

The reason is that adjacent keratin bundles in human hair can be hydrogen bonded, and there are more water molecules in humid air, so it is easier to form hydrogen bonds between keratin bundles in humid weather. When the amount of hydrogen bonds is enough, the hair will produce more bends... Of course, this bond is weaker, so it will recover after drying, quack quack

But friends with curly hair, don’t feel distressed. Your hair has made great contributions to science. In the [-]th century, a Swiss scientist with curly hair, Saussure, used this as a principle to invent the first hair in human history. A hair hygrometer...
