On Chinese New Year's Eve, the family is reunited.

In a small two-story building in Guting Alley in the south of Ningzhou City, a tragic incident occurred, and a family of seven with a single surname, including a three-year-old girl, were all killed.

At the end of the small corridor on the first floor, there was a man who was the man of the family.

The medical examiner was performing an autopsy on him, and he had only one wound on his body, which had been stabbed into the heart with a single-edged dagger.

This knife is fast, accurate, and ruthless.

A lethal knife without dragging mud and water.

If this is changed to the era of martial arts, he will definitely be a master.

Master, this is a master.

"The wound is 3.5 centimeters long, and it is a small dagger, probably a single-edged dagger such as a fruit knife." Zeng Lan measured the shape and size of the wound and said seriously.

"This knife avoids the ribs in the chest and is very accurate, and the murderer should have a special understanding of the anatomy of the human body." Ren Qiushi paused and added.

A fruit knife is stabbed into the heart, the knife is at least 5 or 6 centimeters long, and after the fruit knife is pulled out, arterial blood will splash out of the wound, and it will be sprayed 3 to 5 meters away in an instant. The victim will be paralyzed in a second, fall into a coma in ten seconds, and die within a few minutes.

After performing an on-site autopsy on the first body, the medical examiner went into the living room and performed an on-site autopsy on the two deceased people on the couch.

The deceased on the sofa was a man and a woman, two elderly people, the male deceased leaned back on the sofa, and the female deceased was lying on her side.

The exact identity of the deceased is not yet known, but for the smooth progress of the autopsy at the scene, Ren Qiushi numbered the body, the middle-aged male deceased at the door was the No. 1 deceased, the male deceased on the sofa was the No. 2 deceased, and the female deceased was the No. 3 deceased.

"The fatal wound of the second deceased was in the throat, the murder weapon was a dagger, and the cause of death was that the carotid artery was cut by a sharp blade, resulting in a large loss of blood in a short period of time, hemorrhagic shock, and finally cardiogenic shock and cerebral hypoxia and death of vital organs." Ren Qiushi used his gloved fingertips to gently examine the neck wound of the second deceased.

"From the direction of the wound, it extends from the Adam's apple to the left posterior side. Judging by the shape and size of the wound, it is the same dagger. Zeng Lan then added.

Ren Qiushi looked at the environment of the scene, the sofa and the coffee table in front of him were all splashed bloodstains, but the sofa on the left side of the deceased was relatively clean and there were fewer blood stains.

"But it is very likely that the murderer was also sitting on the couch, and was sitting on the left side of the second deceased, and then suddenly attacked with a fruit knife." Ren Qiushi muttered to himself, then got up and walked towards the third deceased on the side of the sofa.

Deceased No. 3 was lying on his side on the couch with a fatal wound to his neck.

"It looks like the murder weapon is still the same dagger." Ren Qiushi said lightly.

Although the fatal wound of deceased No. 3 was also severed by the carotid artery, the location and direction of the wound were completely different from that of deceased No. 2.

The wound of deceased No. 3 was located directly below the epiglottis, that is, directly in front of the human neck, and the wound was directed from left to right.

"The deceased was a right-hander, and only with a knife in his right hand would have formed such a wound direction." After Ren Qiushi examined the wound, he said seriously.

Zeng Lan stood on Ren Qiushi's side, assisting Ren Qiushi in the on-site autopsy work, and at the same time carefully recording Ren Qiushi's findings on the corpse investigation form.

"The murderer was sitting next to the second deceased, suddenly cut his throat with a knife, and then walked in front of the third deceased. Ren Qiushi calmed down, and restored the situation of the crime according to the position of the two corpses and the direction of blood splashing.

Just when the on-site investigation work and the on-site autopsy work were in full swing, three people walked in outside the door.

I looked at them and laughed, because the three of them were my colleagues in the serious crime team: Lin Zifan, Jiang Tingbai, and Xue Hang.

On Chinese New Year's Eve, after they received the case, they also rushed immediately.

I settled down, looked at them and said in a deep voice: "Old dog, cooperate with the technical team to conduct on-site investigation; Zifan, check whether the doors and windows are damaged; Xue Hang, in the periphery of Guting Alley, retrieved surveillance video; Xiaomeng, contact the household registration department to confirm the identity of the deceased! ”

"Yes!"

After the assignment of tasks, everyone performed their duties and began the investigation and investigation of the case.

After completing the autopsies on the scene for the second and third deceased, Ren Qiushi and Zeng Lan got up and walked into the kitchen on the first floor.

There was a female deceased here, who was the mistress of the house.

The crime scene in the kitchen is the bloodiest, if the three deceased No. 1, No. 2, and No. 3 all died from the sudden attack of the murderer, then in the kitchen, the No. 4 deceased must have had a fierce fight with the murderer.

In the kitchen, there were blood splatters everywhere, pots and pans were all on the floor, and debris was flying everywhere. The dumplings that had been wrapped were scattered all over the ground, and after being splattered with blood and soaked in pools of blood, they had turned red.

Deceased Number Four sat slumped in the corner, his eyes fixed in the direction of the kitchen door.

It is believed that at the time of the crime, she must have been staring at the back of the murderer leaving, until the murderer disappeared at the door of the kitchen.

Such a small place, especially the scene of a crime after a fight, if you rush in, it will definitely destroy the scene.

Therefore, the two forensic doctors and I stayed at the door of the kitchen for the time being, waiting for the technical team to finish the investigation of the crime scene.

The technical team was carefully investigating the room using the biological material discovery device, and saw that the physical evidence number plates in their hands were constantly placed in various positions in the kitchen, and each physical evidence number plate represented that the technical team had found clues there.

Fingerprints, footprints, hair, and other physical evidence that most often appears at the scene were found one by one, followed by the collection of one by one, and the last one was put into the physical evidence bag.

The deceased had flour on her hands, indicating that she was making dumplings in the kitchen at the time of the murder, when the murderer suddenly broke in with a knife, and then she and the murderer started a fierce struggle, knocking over many decorations in the kitchen.

After the technical team left the field, the two forensic doctors entered the scene to examine the body.

Pools of blood had formed on the kitchen floor, and even if everyone was wearing shoe covers, they would still feel the somewhat sticky suction sensation of stepping on the blood.

This feeling is completely different from stepping on water, and the physical and psychological impact is very strong.

In particular, there is a female corpse sitting in the corner, staring at you with wide eyes......
