I'm not a super cop

Chapter 149 Relationships
After the report from the Forensic Medicine Department, Shao Yong, Li Yi, and He Xiaoli respectively reported the situation of the three dumping sites.

从长桥公园内的脚印被雨水冲刷的程度看，凶手抛尸时间，大致应该是11月10号的晚上是10点到11月11号的凌晨3点之间。

But other than that, the investigation results of the three sites were all helpless. Except for a few footprints obtained in Changqiao Park, the other two sites combined did not find even half a fingerprint.

Since the body disposal site on Zhonghe Road was discovered relatively early, the third team also conducted a preliminary visit within a radius of 500 meters.

As for the scene at the fork in the back door of the shopping mall, because the surrounding residents are relatively dense and there are many mobile people, the initial visit has only been carried out for a little while.

However, all the surveillance cameras that can be transferred around the three scenes have been taken. As long as the suspect dares to show up in it, he will definitely not escape the law.

"In the corpse dismemberment case, it is difficult to restore the corpse. During the period before the autopsy report is released, our investigation mainly focuses on these aspects."

After listening to the reports from all parties, Team Lei decisively deployed the next phase of the investigation: "First, the technical team seized the time to check and monitor, find suspicious persons, and cooperate with the forensic department to inspect the macro and micro traces on the scene, and strive to be scientifically There has been a breakthrough in the evidence.

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

Determine the identity of the victim, this is the first key node we want to break through!
After the identity of the victim is determined, while sorting out his interpersonal relationship, we need to find the location where the victim last appeared, the location where the victim first contacted the murderer, the location where the murderer initially attacked the victim, and the location 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 the killer's flaws, and the probability of solving the case will be higher!Is everything clear? "

"understand!"

After the meeting was over, the forensic science department and the technical team entered into a tense overtime state as usual, and Xiao Ran and other criminal investigators were not allowed to rest. Except for a few colleagues who were on duty, the rest of them hurriedly formulated the next step of the search plan.

All the preparations were done, it was close to midnight.

After finishing a day's work, Xiao Ran didn't rush back to the apartment, but went to Team Lei to get the old case file from 15 years ago, and came to the duty room. ——From 0:4 to [-]:[-] tonight is 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 incident time of this old case was November 11, Friday of that year.The original reporter was naturally Aunt Zhang.

After receiving the alarm that morning, the police immediately dispatched the police. After inspection, it was confirmed that the meat in the plastic bag came from a human body. After counting, it was 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 remains of the broken body at the location of today's shopping mall and in Changqiao Park.

The forensic doctor at that time, after identifying the bones, hair, and muscle tissue, judged that the body parts at the three dumping sites came from the same woman.

However, due to the serious damage to the body and the fact that the technical means at that time were far inferior to today's, 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 handling of the corpse was a bit rough. Except for the relatively neatly cut pieces of meat in plastic bags, the method of cutting off the bones seemed a bit blunt.

The split surface of the bone back then had rough horizontal lines and many dents around it. Judging from the cross-section of the victim's bone, the forensic doctor should have used an ax, a hand saw and a kitchen knife to decompose the body first.

Then carefully remove the pieces of meat attached to the bones.

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

Although he did not actually come into contact with the mutilated corpse this time, according to what he witnessed and what Xue Qingxia said, in terms of the method of dismembering the corpse alone, the perpetrators of the "Double 11 Case" obviously had better technical means than 15 years ago The murderer is much smarter.

However, this alone is not enough to conclude that the murderer of the two before and after has its own person, after all, 15 years have passed.

Such a long period of time can completely make the murderer who was a 'fledgling' grow into a 'skilled' criminal.

However, if the two cases were really committed by the same person, and the two were separated by 15 years, then the age of the murderer must be at least close to 40 years old.

However, from the few footprints left in Changqiao 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.

For a middle-aged person in this age group, according to the material level of their growth years, it is too conspicuous to have such a height.

Xiao Ran shook his head, and continued to look through the files from that year. After seeing the back, he finally understood why Team Lei decided that the murderer in the two cases was not the same person.

In these two cases, apart from the fact that the corpses were divided into hundreds of pieces and the clothes were neatly folded, in terms of other handling details, the two cases were quite different.

In the old case 15 years ago, the deceased’s head, internal organs and skin 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 stitching the body together.

The forensic doctor at that time inferred that the appearance of these situations should be that after the murderer killed the deceased, he did not deal with it immediately. Instead, he placed the body in a low-temperature environment and frozen it for a long period of time.

When the murderer wanted to dismember the corpse, he found that the corpse had been frozen. If it thawed, it would not be decomposed in a short time. So he found an ax to split the corpse into large pieces, and then used boiling water to defrost it forcibly. There are signs of being burned.

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

In response to this phenomenon, the task force at the time deduced that it should be that after the murderer decomposed the corpse, he was not eager to throw the corpse away, but temporarily frozen the broken corpse.

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

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

From this point of view, the IQ and cultural level of the murderer were relatively high back then, 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 it was decomposed, it was thrown out along the route of the old case.

In addition, there is another extremely significant difference, which is at the corpse dumping point in Changqiao Park.
