After his old policeman gave these orders, he was cautious, and without destroying the traces of the scene, he followed the blood trail on the ground all the way to the basement floor. It is not difficult to see from the layout below that this is a small screening room of the owner's house.

There is a huge white curtain on the wall, and a large red sofa in a semicircle. But on that circular sofa, there were a few people lying crookedly at this time......

The blood stains on their bodies were very close to the color of the sofa under them! The old policeman immediately ran over to check to see if there was any living mouth. But unfortunately, they are all cold corpses.

Bai Jian and the others had been controlling the owner of the villa, Pang Tianmin, so they rushed over as soon as possible. According to the investigation of the trace personnel at the scene, it was found that the first scene where these people were killed was on the first and second floors.

The murderer killed him with a knife, his methods were very sophisticated, without a trace of procrastination, and he was directly rushing to kill you. There is no intention to vent anger, so it is not like revenge, and from the perspective of the technique, it should be more likely to be extinguished.

But judging from some of the circumstances at the scene, it was more like a robbery, the villa was turned inside and out, most of the valuable things were taken away, and the surveillance at home was all destroyed, and nothing was recorded.

However, according to the forensic doctor's detection of the liver temperature of the corpse, coupled with the time when the link was broken, the investigators analyzed that the time of the crime should be after 22 o'clock in the evening. Moreover, there is no trace of the door being pryed, and it should be the door opened by the victim.

In the case of robbery, then the first victim should have been killed at the door. However, according to the analysis of the blood stains on the ground, the first victim died on the way from the living room to the kitchen, and was stabbed on the neck from behind, which can be proved by the blood splattered on the dining table. In this way, it shows that the victim and the murderer knew each other, at least his unsuspecting acquaintances.

After the murderer killed the first victim, that is, Pang Tianmin, perhaps because he heard the sound of the living room, the second victim appeared.

According to the analysis of the case-handling personnel, it was already past 22 o'clock, and the two children and Pang Tianmin's wife Liu Juan should be in the upstairs bedroom, so the second victim should be Pang Tianmin's wife.

Because her room was on the first floor, she heard something unusual in the living room and wanted to come out to take a look, but when she saw Pang Tianmin who had his neck wiped off, she immediately let out a scream.

But the murderer should not have given her a second chance to speak, this time he cut the old lady's carotid artery and throat head-on. According to the investigators' speculation, there should have been no need for the murderer to kill the others at that time, but because he was looking for something in the house, he had to kill the rest of the people one by one.

The remaining three people are Pang Tianmin's wife Liu Juan and their son and daughter, according to the analysis of the bloodstains at the scene, Liu Juan should have died in the corridor on the second floor, she should have come out of the children's room at that time, and wanted to go downstairs to see the situation on the first floor. It was at this time that the murderer walked up the stairs......

As a mother, Liu Juan's first reaction should have been to run to the child's room, but the murderer quickly caught up and killed her with a knife. After that, the murderer went into the master bedroom and rummaged through it, taking some valuables.

It was at this time that he found the two children who had been peeking at him behind the door, and the murderer did not hesitate to push the door and enter the children's room, killing the two children.

After that, the murderer dragged all the corpses to the basement, and Bai Jian analyzed that the murderer did this, most likely to confuse the public and make trouble for the police to detect, so that they thought that this was a burglary and murder case.

And the real purpose of the murderer must not be to rob money, although his rummaging is very purposeful, and he also took away some seemingly valuable things, but from the perspective of the murderer's modus operandi, it is definitely not as simple as an ordinary burglary and murder case.

According to the dossier, the most strange thing is that there is no trace of the murderer in the entire crime scene. Footprints, fingerprints, all gone. In addition to the blood sprayed by the victims who were killed by him head-on, there should be a part of the blood sprayed directly on the murderer's body.

The amount of bleeding in the carotid artery of the human body is very large, although it was night, but if you don't want to be discovered, the murderer can only wear dark clothes, so that passers-by will not be found in the dim light.

After closing the file, my mind was full of the murderer's murder, and although I had never seen it with my own eyes, my heart began to make up for it involuntarily.

Bai Jian saw that I was meditating with my eyes closed, so he asked me in a low voice, "Now we have no clues about the murderer, so we have to ask you, a master, to come over and take a look at the victim's body." ”

At this time, I suddenly opened my eyes, turned the file back to the first page, glanced at the time of the crime, and then immediately sank in my heart, wasn't this the night before I met Han Jin?

So I asked Bai Jian angrily, "Didn't you already control this Pang Tianmin at that time? How could you still be silenced?"

When I asked Bai Jian, his face turned red and he said, "Don't mention it!" The two young policemen who were sent there at that time were squatting and squatting well, but they suddenly heard the security guards walking by their car say that a group of old women had come to the building in front of them to beat Xiao San, and it was said that they had blocked Xiao San and were beating him to death! My two men were young and inexperienced, so they went over and took a look, and it was estimated that the murderer entered the door at this time. At that time, the curtains of the villa were drawn, and the privacy was very strong, and if it wasn't for the loud noise inside, it would be impossible for people outside to know what was going on inside......"

After listening to him, I teased, "Don't make excuses for yourself, a mistake is a mistake...... And your men have been there all night after that?"

Bai Jian nodded and said, "No, according to their squatting records, the lights in the villa were turned off at 23:15, but now it seems that it should be the murderer who put out all the lights." ”

"Well, it should be, and it's highly likely that the killer left the back of the villa after that time. Did you see any suspicious people in the vicinity?" I said.

Bai Jian said helplessly at this time, "The weird thing is here, this murderer seems to know that if you avoid all the surveillance, there are a total of 4 probes near Pang Tianmin's villa, but none of them have photographed any suspicious people." ”
