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

Judging from the extent to which the footprints in Longbridge Park were washed away by the rain, the time when the murderer threw the body should have been between 10 o'clock on the night of November 10 and 3 o'clock in the morning on November 11.

However, other than that, the results of the investigation of the three sites were all clueless, except for a few footprints obtained in Longbridge Park, the other two sites combined did not find even half of the fingerprints.

Due to the relatively early discovery of the body dumping site on Zhonghe Road, the third team also conducted a preliminary visit within a radius of 500 meters.

At the scene at the fork in the back door of the shopping mall, because the surrounding households are relatively dense and the flow of people is large, only a small half of the initial visit has been carried out so far.

However, all the surveillance that can be called around the three scenes has been taken, and as long as the suspect dares to show his face in them, he will not be able to escape justice.

"In the case of corpse crushing, it is difficult to recover the body, and during the period when the autopsy report has not yet been given, our investigation direction mainly includes these aspects. ”

After listening to the reports of all parties, the Lei Brigade resolutely made arrangements for the next stage of the investigation: "First of all, the technical team seized the time to check the monitoring, find suspicious persons, and cooperate with the forensic department to inspect the macro and micro traces at the scene, and strive to make a breakthrough in scientific evidence.

Secondly, the investigators of each team paid close attention to the information on the missing persons provided by the sub-bureaus and subordinate police stations, and searched for the recently disappeared young woman throughout the city.

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

After the victim's identity is confirmed, while sorting out his interpersonal relationships, we should find the last place where the victim appeared, as well as the place where the victim and the murderer initially came into contact, the place where the murderer initially attacked the victim, and the place where the murderer killed the victim.

As long as we have a detailed grasp of these locations, it is very likely that we will find out the murderer's exposed feet, and the higher the chance of solving the case!

"Understood!"

At the end of the meeting, the forensic medical department and the technical team entered a tense overtime state as usual, and Xiao Ran and other criminal investigators were not allowed to rest, except for a few colleagues on duty, the rest of the people hurriedly formulated the next search plan.

All the preparations were made, and it was close to the early hours of the morning.

After finishing a day's work, Xiao Ran did not rush back to the apartment, but asked the Lei Brigade to get the old case file from 15 years ago and came to the duty room. - From 0:00 to 4:00 tonight, it's his duty time.

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

The time of this old case was Friday, November 7 of that year. The original informant was naturally Aunt Zhang.

After receiving the alarm that morning, the police immediately dispatched the police, and after inspection, it was confirmed that the meat pieces in the plastic bag came from the human body, and after counting, it was found that there were nearly 100 pieces of meat and three fingers in the bag.

Later, until noon the next day, the police found the remains of the broken body at the location of today's mall and in Longbridge Park.

At that time, the forensic doctor, after identifying the bones, hair, and muscle tissue, determined that the body parts at the three dumping sites were from the same woman.

However, due to the severity of the destruction of the corpses and the fact that the technical means at that time were far inferior to today's, it is not possible to draw an accurate conclusion about the time when the deceased was killed and the cause of death.

Judging from the archives, the murderer's treatment of the corpse was a little rough, except for the relatively neat pieces of meat cut in the plastic bag, and the technique of amputating the bones was a little stiff.

The forensic doctor judged from the section of the victim's skeleton that the murderer should have used an axe, a handsaw, and a kitchen knife to first decompose the body in large pieces.

Only then do the pieces of meat attached to the bones be removed in greater detail.

Xiao Ran caressed the somewhat yellowed files, and the scenes of yesterday's corpse dumping scene flashed in his mind one by one.

Although he did not actually come into contact with the corpse this time, according to his witnesses and what Xue Qingxia said, judging from the method of dismembering the corpse alone, the perpetrators of the 'Double 11 Case' obviously had much more technical means than the murderer 15 years ago.

However, this alone is not enough to conclude that the murderers of the two before and after are their own, after all, fifteen years have passed.

For such a long time, it is completely possible for the 'fledgling' murderer to grow into a 'skilled' criminal.

However, if the two cases were really committed by the same person, and the two were separated by fifteen years, then the age of the murderer would be at least close to forty years old.

But from the footprints left in Longbridge Park, it is preliminarily judged that the person who left the footprints should be a big man with a height of about 1.9 meters.

Middle-aged people of this age, according to the material level of their growth years, have such a height, which is too conspicuous.

Xiao Ran shook his head, continued to look through the files of the year, and when he saw the back, he finally understood why the Lei Brigade determined that the murderers in the two cases were not the same person.

In these two cases, except for the corpses being divided into hundreds of pieces and the neatly folded clothes, in other processing details, the two cases can be said to be very different.

In the old case 15 years ago, the deceased's head, internal organs and flesh showed signs of being scalded by boiling water, and the forensic doctor found that the deceased's pelvis and lower body parts were missing after splicing the body together.

At that time, the forensic doctor deduced that these situations should have occurred after the murderer killed the deceased, and did not deal with it immediately, but placed the body in a low-temperature environment and froze it for a long time.

When the murderer wanted to divide the body, he found that the body had been frozen, and if it was thawed, it could not be decomposed in a short time, so he found an axe to split the body into large pieces, and then forcibly thawed it with boiling water, so there were signs of being scalded.

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

In response to this phenomenon, the task force at that time deduced that it should be that after the murderer decomposed the body, he did not rush to throw the body, but temporarily froze the broken body.

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

As for the missing pelvis and lower body parts of the year, the task force deduced that the victim should have been violated by the murderer before his death, so the murderer did not throw them out with the corpse.

From this point of view, the murderer's IQ and education level were relatively high, and DNA detection and detection were already known at that time.

In this 'Double 11' case, the deceased's pelvis was not lost, and judging from the body parts, the murderer did not deliberately keep the body, and soon after the decomposition, he threw it along the route of the old case.

Another significant difference is at the dumping site in Longbridge Park.
