After the forensic department report was completed, Shao Yong, Li Yi and He Xiaoli reported on the situation of three corpse-dumping sites respectively.

Judging from the extent to which the footprints in Changqiao Park were washed by rain, the time when the murderer threw the body should be between 10 o'clock on November 10 and 3 o'clock on November 11.

However, in addition to this, the survey results of the three sites were all at a loss. Apart from the few footprints obtained in Changqiao Park, the other two sites were not found even half of the fingerprints.

Since the Zhonghe Road corpse throwing site was discovered early, Team 3 also conducted a preliminary visit within a radius of 500 meters.

At the intersection of the back door of the shopping mall, the site was at the fork in the surrounding area and the number of migrant workers was large. It has only been a half of the initial visits since now.

However, all the surveillance monitors that can be transferred around the three scenes have been taken. As long as the suspect dares to show up, he will inevitably be unable to escape the French Open.

"The corpse dismemberment case is difficult to recover the body. During the period when the autopsy report has not been given, our investigation direction mainly includes these aspects."

After listening to reports from all parties, Lei team decisively deployed the next stage of investigation: "First, the technical team seized the time to check the monitoring, find suspicious people, and joined hands with the forensic department to inspect the macro and micro traces on the scene, striving to make breakthroughs in scientific evidence.

Secondly, the investigators of each team closely pay attention to the information of missing persons provided by various branches and subordinate police stations, and look for the recently missing young women throughout the city.

Determining the identity of the victim is the first key node we need to break through!

After the identity of the victim is determined, while sorting out his interpersonal relationships, we must find the place where the victim appears in sequence, as well as the initial contact between the victim and the murderer, the place where the murderer initially attacks the victim, and the place where the murderer kills the victim.

As long as we have grasped these locations in detail, we are likely to find the exposed foot of the murderer, and the higher the chance of solving the case! Are you all clear?"

"clear!"

After the meeting, the forensic department and the technical team entered a tense state of overtime as usual. Xiao Ran and other criminal investigation personnel were not allowed to rest. Except for some colleagues responsible for duty, the rest of the people rushed to formulate the next search plan.

All preparations are done, and it is almost the early morning.

After completing the day's work, Xiao Ran did not rush back to the apartment, but instead asked Lei Brigade to get the old case files from 15 years ago and came to the duty room. Tonight, 0:00 to 4:00 is his duty time.

Lying on the simple and narrow shop in the duty room, Xiao Ran finally saw the old case that had been hovering in his mind for a long time.

The time of the old case was on Friday, November 7th of that year. The original reporter was naturally Aunt Zhang.

After receiving the alarm that morning, the police immediately sent a police officer. After checking, they confirmed that the meat in the plastic bag came from the human body. After counting, they found that there were nearly a hundred pieces of meat and three fingers in the bag.

Then until noon the next day, the police found the wreckage of the corpse at today's shopping mall location and in Changqiao Park.

After identifying bones, hair and muscle tissue at that time, the forensic doctor determined that the three corpse throwns were from the same woman.

However, due to the serious destruction of the corpse and the technical methods at that time were far inferior to today, it was impossible to draw an accurate conclusion on the time of the deceased's death and the cause of death.

Judging from the archives, the murderer's treatment of the corpse was a bit rough. Except for the neat pieces of meat cut in the plastic bag, the method of cutting the bones seemed a bit stiff.

The bone segmentation surface was rough and there were many dents around it. The forensic doctor judged from the section of the victim's bone that the murderer should have used an axe, a hand saw and a kitchen knife to decompose the body in large pieces first.

Then I carefully removed the pieces of meat attached to the bones.

Xiao Ran gently stroked the yellowed file, and the scenes of the scene of the body throwing yesterday flashed through his mind.

Although he did not actually contact this time's dismemberment, based on his sightings and what Xue Qingxia said, just judging from the method of dismembering the corpse, the perpetrators of the "Double 11 case" have obviously much more skillful technical methods than the murderer fifteen years ago.

However, just this point alone is still not enough to conclude that the murderers of both sides have their own personalities, after all, fifteen years have passed.

Such a long time can completely allow the "first-coming" murderer to grow into a "superbian" criminal.

However, if the two cases were really done by the same person, and the two were fifteen years apart, the murderer's age would be at least close to forty years old.

But from the footprints left by Changqiao Park, it is preliminary to judge that the footprints left should be a big man about 1.9 meters tall.

Middle-aged people of this age are too conspicuous to have such a height according to their material level in their growth years.

Xiao Ran shook his head and continued to look through the files of that year. After seeing it, he finally understood why Team Lei determined that the murderers of the two cases were not the same person.

In these two cases, except for the bodies being divided into hundreds and neatly stacked clothes, the two cases are very different in other handling details.

In an old case 15 years ago, the deceased's head, internal organs and flesh showed signs of burning water. After the forensic doctor spliced ​​the body, he found that the deceased's pelvis and lower body were missing.

The forensic doctor inferred that the occurrence of these situations should be that the murderer killed the deceased and did not deal with it as soon as possible. Instead, the body was placed in a low-temperature environment and frozen for a considerable period of time.

When the murderer wanted to dismember the body, he found that the body had been frozen. If it bleeds, it would not be able to decompose in a short time. So he found an axe to split the body into large pieces, and then forced it to thaw with boiling water, so there was a sign of being scalded.

As for when Aunt Zhang found the meat pieces at that time, she claimed that the meat pieces in the bag had not completely thawed.

In response to this phenomenon, the task force at that time inferred that the murderer, after decomposing the body, did not rush to throw it away, but temporarily freeze the body.

After the murderer found the corresponding location, the frozen corpses were discarded in batches.

As for the missing pelvis and lower body parts that were found, the task force inferred that the victim should have been violated by the murderer before his death, so the murderer did not throw him out with the corpse.

From this point of view, the murderer's IQ and cultural level were relatively high at that time, and he had known about DNA's detection and detection in that era.

In this "Double 11" case, the deceased's pelvis was not lost. From the corpse, the murderer did not deliberately keep the body. Shortly after the decomposition, he threw it along the old case route of that year.
