It is a detached two-storey villa with a living room, dining room, and bedrooms on the first floor, two bedrooms and a utility room on the second floor, and a toilet on each upstairs and downstairs.

As soon as I walked through the door, a pungent smell of blood came to my nose.

In the room, as Sister Ma said, there were blood stains everywhere he looked.

There are two bodies on the floor of the living room on the first floor, a male corpse in a supine position and a female corpse in a prone position.

The two were lying in a pool of blood, their pajamas were all soaked with blood, and their faces were also soaked with blood, so they couldn't see their faces clearly, and they could only judge based on their body shape and other physical features.

The male deceased was middle-aged and looked to be between fifty and sixty years old, while the female deceased was younger and looked less than thirty years old.

In order to facilitate the examination of traces and autopsies, the male deceased is temporarily marked as the first deceased and the female deceased as the second deceased.

Forensic doctor Jiang Xiran and forensic assistant Zhou Xiaoyi settled down and immediately began the preliminary autopsy work at the scene.

Ling Zizhen walked up to Lu Ke and pointed to the stairs: "The other two deceased are in the bedroom upstairs. ”

Lu Ke nodded, and walked up the stairs on the second floor.

There were obvious dripping blood stains on the steps, which continued down the staircase steps to the second floor. It seems that the murderer first killed people on the first floor, and then walked up to the second floor with the murder weapon to continue the crime, and this string of dripping blood should have dripped from the murder weapon.

Walking up to the second floor, with continuous flashing lights in front of me and the "click" sound of the criminal investigation camera in my ears, the technical team is conducting on-site investigation work around the bedroom.

Walking to the door of the first bedroom, the room was full of splattered blood, a middle-aged female corpse was lying on one side of the bed in a prone position, and a boy's corpse was lying on the bed in a supine position. The middle-aged woman looks about the same age as the middle-aged man downstairs, and the boy should be only three or four years old.

The middle-aged woman is tentatively the third deceased and the boy is the fourth deceased.

There is no doubt that this was a case of extermination, and the deceased Wu Changhai's family of four was killed.

Faced with the bloody scene of the death of four people, everyone subconsciously frowned. Especially Mo Yufei, when her eyes fell on the boy on the bed, she couldn't bear to turn her head away.

Su Simeng patted her lightly on the shoulder, and said lightly: "Let's go, go back to the first floor and have a look." ”

Walking down the stairs, Ling Zi really stood at the top of the stairs and looked at them, and asked in a low voice, "Do you see it?" ”

Lu Ke nodded and did not speak.

"The case of destroying the door is too miserable." Su Simeng replied.

Ling Zizhen took a deep breath and said seriously: "The technical team is still investigating the scene and found bloody footprints, but the coverage is serious, incomplete and not obvious, and it cannot be used as a basis for investigation, but it can be used as evidence to identify the murderer." ”

Lu Ke slowly walked down the steps and asked him, "Can you determine the nature of the case?" ”

Ling Zizhen said in a deep voice: "After all, it is a case of burglary, and the possibility of vendetta is extremely high, but there are traces of turning at the scene of the crime, and the possibility of robbery cannot be ruled out." ”

He paused, and added: "There are no traces of damage to the doors and windows, the murderer came in through the gate, and there are no obvious traces of struggle at the scene, so it is more likely that acquaintances committed crimes." ”

Lu Ke nodded, and walked towards the deceased in the living room, he had just walked a few steps, and suddenly said to Mo Yufei behind him: "You go and cooperate with the police in the jurisdiction to determine the identities of the four deceased as soon as possible, as well as social relations." ”

Mo Yufei was stunned for a moment, and then said, "Okay, I'll go and come back quickly." ”

Looking at Mo Yufei's back as she sped up her steps to leave, Su Simeng said to Lu Ke: "As a criminal policeman, it is the only way to go out to see the corpse at the scene, and you can't let her avoid the scene investigation every time." Moreover, this is a case of extermination, which is a very typical case and an important accumulation of experience. ”

Lu Ke said as he walked: "Everything has to be adapted, and I am going to transfer her to the internal office to see what clerical jobs are available for her." ”

Su Simeng smiled: "Lao Mo was notoriously strict with you at the beginning, and you are like this to us, it is not your character to be so kind." But then again, Lao Mo really disliked you very much at that time, and once wanted to transfer you to the archives department as an administrator. ”

Lu Ke sighed: "If I were replaced by any rookie criminal policeman, I would not do this, but I always can't pass this level in my heart, I am really afraid that she will make a mistake one day in the future." ”

Su Simeng looked at Lu Ke and said in a deep voice: "Don't worry, the tiger father has no dog girl, I did see Lao Mo's shadow on her." Firm your inner thoughts, and if Lao Mo is here, he will support you in doing so. ”

Lu Ke nodded seriously, didn't say anything more, and walked over to the corpse.

Jiang Xiran and Zhou Xiaoyi are conducting an autopsy, and the two have just finished examining the body of a middle-aged man.

"Deceased No. 1 was on the edge of the couch with fatal injuries overhead, and the cause of death was a severe head injury caused by a skull fracture. There was a large amount of blood soaked in the wound, the hair was sticking together, and the shape of the wound could not be clearly distinguished for the time being, but it did not look like a sharp wound, but it should have been caused by a blunt force. The mortis was very severe, showed no signs of relief, and the time of death would not have been more than twenty-four hours, but it must have been more than twelve. ”

Zhou Xiaoyi assisted in the autopsy while recording the autopsy.

The middle-aged male corpse and the young female corpse were very close to each other, only separated by a coffee table, Jiang Xiran and Zhou Xiaoyi moved their bodies and came to the female deceased.

Jiang Xiran gently lifted the head of the female deceased and examined it carefully: "The fatal injury of the second deceased is also on the head, and there is no obvious injury on the body, and the preliminary judgment is that the injury tool is the same as that of the first deceased." ”

She gently pressed the female deceased's skull, and there was a clear bone rubbing sensation: "There are two injuries to the head, one on the top of the head and one on the occipital position of the back of the head, which should also be caused by blunt force blows, and there is a skull fracture on the top of the head, and the injury to the occipital part is obviously more serious, and the skull has collapsed, revealing a hole." She was supposed to be standing at the time of the first blow, and the second blow was made up after she was injured and fell to the ground. The time of death, like the first deceased, was between twelve and twenty-four hours. ”

Lu Ke stood behind Jiang Xiran and asked seriously: "In other words, someone took a blunt object and knocked the heads of the two of them?" ”

Jiang Xiran nodded and said, "That's the case, but for the time being, we can't judge the injury tool based on the wound, so let's talk about it after pulling it back to the dissection room for debridement." ”

Lu Ke thought for a while, and muttered: "Within twelve hours to twenty-four hours, that is to say, the time of the crime should have been last night." ”

Jiang Xiran added: "That's right, the first and second deceased were wearing indoor slippers on their feet, this is a burglary homicide, and it was committed by an acquaintance." ”

At this moment, Jiang Xiran and Ling Zizhen both mentioned acquaintances committing crimes.

Jiang Xiran paused, and then said: "The murderer hit the No. 1 deceased once, but hit the No. 2 deceased twice. ”

Lu Ke then said: "This shows that from the perspective of the motive for killing, the murderer's hatred for the second deceased is deeper than that of the first deceased." ”

Jiang Xiran stood up, looked at the staircase with the blood stains on the ground, and said lightly: "After the murderer killed, he didn't move the body, judging from the direction and consistency of the dripping bloodstains, he walked directly to the second floor, and his determination to kill was very heavy. In this way, the hatred between the murderer and this family is not small......"
