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

After the preparations were completed, the forensic department and a group of technicians rushed in and carried out the most detailed scientific investigation of Qian Shuangshuang's rental house.

Look at the approximate location of the pool of blood that the technician has demarcated on the ground, as well as the four areas marked on the floor tiles with slash marks.

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

"Yes, judging from the slashing marks on the ground, the previous judgment of the forensic department was correct, the murderer first decomposed the body in large pieces, and then took it away and then carried out fine dismemberment. ”

He Xiaoli said: "Wang Junming, they have gone to the nearby surveillance, there are a lot of cameras in this area, but there is still a blank area for surveillance." ”

"This murderer is a little cautious. ”

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

He Xiaoli nodded.

Indeed, fifteen years ago, there were only three places where the body was dumped, and the police searched the entire city but could not find the crime scene.

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

Xiao Ran looked at the range of blood stains circled by the technical team on the floor, although the blood stains on the floor had been cleaned up by the suspect, the suspect did not seem to have cleaned it carefully, so that there were many microscopic traces.

Based on the trace amount of blood, the technician was able to roughly draw out the original pool of blood and the direction in which the pool of blood would stretch when the body was later moved.

"If the bloodstains here do belong to Qian Shuangshuang himself. Judging from the shape of the marked primordial pool of blood, Qian Shuangshuang did not struggle after being injured and falling to the ground. ”

Xiao Ran recounted the previous inference, rubbed the tip of his nose and said: "If a normal person's throat is cut, he will definitely struggle violently, and from the demarcation of the blood pool area on the floor, the formation of the original blood pool is very natural.

Even if the murderer held down her body after injuring Qian Shuangshuang, it would leave traces of struggle, but this primordial pool of blood was as if a suicide was going to die safely, allowing the blood in her 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 demarcated the first time formed?"

"No, inferring from the trace amount of blood, we now believe that these blood stains were formed in two time periods, but we will have to wait until we go back for further examination. ”

Xue Qingxia shook her head and said, she stood up, pointed to a few marked areas, and said to Team Lei: "The three blood stains on the wardrobe, the bed sheets, and the bed legs come from the fresh blood that spurted out after the deceased was injured.

This pool of blood near the foot of the bed is the largest, from which it can be inferred that the amount of blood required to form this pool of blood can be inferred. In other words, the victim died before the pool of blood was completely formed. ”

Brigade Lei listened quietly.

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

At the beginning of this drag, a small amount of blood was concentrated, but after a short distance, it decreased sharply, and there were many blank areas. We judged that the murderer should have dragged the body for a long time after the victim's death, that is, when the blood in the pool of blood was about to dry up, and the specific time should have been about an hour and a half after the victim's death. ”

"An hour and a half?"

Listening to Xue Qingxia's narration, everyone present was a little surprised, the murderer actually dragged the body for dismemberment an hour and a half after the death, what would the murderer do at the scene in this hour and a half?

Looking at Qian Shuangshuang's corpse in a daze? Still thinking about what to do next?

But even if you hesitate, it takes an hour and a half to think about the problem, the time is too long, after all, the longer you stay at the scene of the crime, the more flaws you will leave behind, and the greater the probability of being discovered.

"Originally, when a corpse died, the corpse should have been parallel to the bed. ”

Xue Qingxia continued: "After the murderer moved the deceased to the end of the bed, perpendicular to the bed, he may have used a tool similar to a kitchen knife to cut off the limbs of the deceased. ”

"This is basically the same as what you described yesterday. ”

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

- If the murderer is still in a state of panic at this time, what can you say about the one-and-a-half-hour blank period before the murderer? If you adjust your mentality, one and a half hours is enough to regain your composure. ”

From this point of view, coupled with the footprints at the scene of the dumping of the body, the murderer is basically not too old, and it is likely that he knows the victim, or the relationship is not bad, and there is even no hatred between the two people. ”

Lei Kang pondered for a while and said, "Only in this way will the murderer still feel guilty and flustered after thinking for an hour and a half. - But if there is no hatred between the two, the murderer will just throw the corpse, why should he chop the corpse into pieces, just to confuse us?"

"No one can say this, and anything is possible until the truth is clarified. ”

Xue Qingxia said: "In addition, a bloody mop was found in the deceased's bathroom, which shows that the murderer should have used this mop to clean the ground before preparing to take the body away." The quirkiest part, though, is here. ”

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

Xue Qingxia said: "As Xiao Ran said just now, when the deceased stood in front of the wardrobe before he was killed, when the blood sprayed out, even if it was messy, there was still a pattern to follow. There are blood spots all around this one, but it's a blank ......"

"So, this position was where things were placed when the deceased was killed, but then they were taken away by the murderer!" He Xiaoli said immediately.

"It should be an item with an important clue, otherwise the killer wouldn't have taken it specifically. Xiao Ran said.

Xue Qingxia asked, "What could it be?" The items that were placed on the wardrobe were probably being watched by Qian Shuangshuang at that time. ”

"On the wardrobe, it's rectangular, it should be a picture frame. ”

He Xiaoli said suddenly: "Could it be a photo of Qian Shuangshuang and the murderer? There is the appearance of the murderer in it! If this is the case, it can make Qian Shuangshuang solemnly put the photo at the head of the bed,...... The killer is her girlfriend?"

"Girls?"

Xue Qingxia shook her head and said, "But judging from the strength of the corpse's bones being chopped, it is obvious that it is the power that only boys can wield. ”

"So, what could this item be on the closet?" said Team Ray in deep thought.

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

She looked at the empty space on the wardrobe and said weakly, "Well, I feel, it looks like there's a tablet here......"
