Soon, Team Lei led a group of technicians to the scene.

After the preparations were completed, the forensic department and a group of technicians entered one after another and conducted the most detailed scientific investigation of Qian Shuangshuang's rental house.

Watch the rough location of the pool of blood drawn by the technicians on the ground, as well as the four areas marked with chopping marks on the floor tiles.

Lei Kang said in a deep voice to He Xiaoli: "It is basically certain that this is the scene where Qian Shuangshuang was killed."

"Yes, judging from the chopping marks on the ground, the forensic department's previous judgment was correct. The murderer first decomposed the body in large pieces and then took it away before dismantling it."

He Xiaoli said: "Wang Junming and others have already drawn nearby surveillance cameras. There are many cameras in this area, but there are still surveillance blank areas."

"This murderer is a little careful."

Team Lei said in a deep voice: "But compared to 15 years ago, we have at least found the crime scene now, which is a big gain."

He Xiaoli nodded.

Indeed, there were only three places for the old case fifteen years ago to throw away the body. The police searched the entire city and found no crime scene. There was no crime scene, so many important inferences could not be straightened out.

"What are you looking at?" He Xiaoli turned her head and asked at Xiao Ran.

Xiao Ran looked at the blood stains circled on the floor by the technical team. Although the blood stains on the floor had been cleaned by the suspect, the suspect did not seem to have cleaned them carefully, leaving many microscopic marks.

Based on the trace amount of blood, the technician can roughly draw out the original pool of blood, and the direction in which the pool of blood is stretched when the body is moved.

"If the blood here really belongs to Qian Shuangshuang himself. Then, judging from the shape of the marked original pool of blood, Qian Shuangshuang did not struggle after being injured and fell to the ground."

Xiao Ran described the previous inference and rubbed the tip of his nose and said, "If a normal person has his throat cut, he will definitely struggle violently. Judging from the blood pool area demarcated from the floor, the original blood pool is formed very naturally.

Even if the murderer pressed Qian Shuangshuang's body after hurting Qian Shuangshuang, it would leave traces of struggle. But this primitive pool of blood seemed to be a suicide victim to die safely, allowing the blood from his body to flow out."

Team Lei frowned, walked to the edge of the blood pool area, squatted down and asked, "Are these blood stains you designated formed as soon as possible?"

"No, we now believe that these blood stains were formed in two time periods, but they will not be finalized until they go back to further test."

Xue Qingxia shook her head and said, she stood up, pointed to the few marked areas, and said to Lei Team: "These three blood stains on the wardrobe, bed sheets, and bed legs are from the fresh blood ejected from the deceased after the injury.

Among them, the area near the end of the bed is the largest, and it can be inferred that the amount of blood needed to form this pool of blood. That is to say, the victim died before this pool of blood was completely formed."

Team Lei listened quietly.

Xue Qingxia continued: "Xiao Ran is right. Judging from the demarcated edge of the blood pool area, the edge line is very natural, that is, the dead have not rolled and struggled, and the arc-shaped irregular trace on the outside should be left by the murderer when he dragged the body to the dismembered position.

At the beginning of this drag trace, the trace blood was concentrated, but it decreased sharply after a short distance, with many blank areas. We judged that the murderer should have dragged the body for a long time after the victim died, that is, when the blood in the blood pool was about to dry up, the specific time should be about one and a half hours after the victim died."

"An hour and a half?"

Listening to Xue Qingxia's narration, everyone present was surprised. The murderer actually dragged the body to dismember him for an hour and a half after he died. What would the murderer do at the scene in the hour and a half?

Are you staring at Qian Shuangshuang's body? Or are you thinking about what to do next?

But even if a person hesitates, he spends an hour and a half thinking about the problem, it will be too long. After all, the longer he stays at the crime scene, the more flaws he leaves and the greater the probability of being discovered.

"When the corpse died, the corpse should be parallel to the bed."

Xue Qingxia continued: "After the murderer moved the deceased to the end of the bed and perpendicular to the bed, he may have used a tool similar to a kitchen knife to cut off the deceased's limbs. We found a few bone fragments in the gaps in the floor tiles, and we will further compare after we go back."

"This is basically consistent with what you described yesterday."

He Xiaoli nodded and then asked again: "However, what you analyzed yesterday, when the murderer first dismembered the dead body, the incision was relatively rough, or the murderer was in a panic state.

If the murderer is still in a panic at this time, what should I say about the previous one and a half hours of the blank period? If you adjust your mentality, one and a half hours will be enough to recover from calmness."

"From this perspective, coupled with the footprints at the scene of the body throwing, the murderer is basically not too old. He is likely to know the victim, or the relationship is not bad, and there is even no hatred between the two."

Lei Kang pondered for a while and said, "Only in this way, the murderer will still feel guilty and panic after thinking for an hour and a half. However, if there is no hatred between the two, it would be fine if the murderer threw the body away. Why did he still cut the body down? Just to confuse us?"

"No one can tell this, and nothing is possible before finding out the truth."

Xue Qingxia said: "In addition, a bloody mop was found in the bathroom of the deceased. It can be seen that the murderer should have used this mop to clean the ground before he was about to take the body away. However, the weirdest place is here."

Xue Qingxia pointed to the wall area on the wardrobe, where there were spots of blood like shower holes, but there was a rectangular blank in the middle of the blood.

Xue Qingxia said: "As Xiao Ran said just now, the deceased stood in front of the wardrobe before being killed. When blood was sprayed out, even if it was messy, there was still a pattern to follow. There were blood spots around this piece, but there was indeed a blank place..."

"So, this location was filled with things when the deceased was killed, but was taken away by the murderer later!" He Xiaoli said immediately.

"That should be an item with important clues, otherwise the murderer would not have taken it away specifically." Xiao Ran said.

Xue Qingxia asked: "What would that be? It's the items placed on the wardrobe, and it's likely that Qian Shuangshuang was watching at that time."

"Put it on the wardrobe, rectangular, it should be a photo frame."

He Xiaoli suddenly said: "Can it be a photo of Qian Shuangshuang and the murderer? There is the appearance of the murderer! If this is the case, can Qian Shuangshuang take the photo of the bedside solemnly... the murderer is her girlfriend?"

"girl?"

Xue Qingxia shook her head and said, "But judging from the strength of the corpse bones being chopped, it is obviously a force that can only be exerted by boys."

"So, what would this item be on the wardrobe?" Lei Guomao fell into deep thought.

Yu Yu, who had been lying on the floor looking for traces, stood up carefully.
