In the forensic autopsy room, Jiang Xiran and Zhou Xiaoyi are still splicing together the corpse parts found at the abandoned construction site.

Unlike other homicide cases, the dismemberment of body pieces is a necessary step that requires not only a high level of expertise, but also a great deal of professionalism and patience.

Because every cut and every knife of the murderer will leave some subtle clues. And sometimes, these subtle clues become the key to solving the case.

When Jiang Xiran was still an intern forensic doctor, he once participated in the investigation of a corpse mutilation case. At that time, the chief surgeon forensic doctor detected a kind of edible peanut oil on the cross-section of the corpse, and determined that the location of the murderer's body should be in a small oil mill.

Many years ago, in the investigation of a corpse shredding case, the forensic doctor found trace traces of wood chips on the corpse, and judged that the murderer's tool for dismembering the corpse was a small gardening chainsaw through the cross-section of the bone, and finally locked the murderer with autism through the subtle dye traces on the plastic bag of the corpse.

Jiang Xiran and Zhou Xiaoyi didn't dare to slack off in the slightest, and stood in front of the dissecting table and worked seriously.

After about two hours, a female corpse with a missing head and part of the musculature was roughly displayed in front of them.

"It's finally over! I feel like my neck won't move anymore. Zhou Xiaoyi let out a long sigh of relief and stretched a big lazy waist.

Jiang Xiran didn't say anything, but turned around and took off his gloves and threw them into the trash, washed his hands silently, and took two tissues to wipe the sweat on his forehead.

"I really didn't expect that forensic medicine is still a manual job." Zhou Xiaoyi was still immersed in the sense of accomplishment of completing the corpse, leaning lazily against the wall, constantly moving his neck, and he could clearly hear the clicking sound from the cervical vertebrae.

He shook his neck, and his gaze fell on Jiang Xiran's back.

Behind the blue anatomical suit Jiang Xiran was already soaked with sweat.

This time the autopsy was performed on highly decomposed corpses, and the dissecting gowns they wore were thicker than usual, with better protection and poor breathability.

Jiang Xiran is a professional forensic doctor, the head of the forensic department, but she is also a girl.

A girl has no fear or complaint in the face of a cold corpse, and what right does a big man have to complain.

Zhou Xiaoyi hurriedly calmed down, stood up straight, and felt even more proud and honored in his heart that he was a forensic doctor.

Jiang Xiran drank a glass of water, and without a moment of rest, he immediately changed into a new pair of latex gloves and returned to the dissection table again.

"Hurry up and get to work, Lu Ke is still waiting for the autopsy report." Jiang Xiran said lightly.

Zhou Xiaoyi nodded, cheered up, and continued to work.

The splicing of the corpse parts just now was just a preparatory work, and now what they have to do is the real autopsy work.

When they once again looked at the corpse on the dissecting table, they all subconsciously shuddered. The shredded corpse itself is enough to make people feel their scalp tingle and shudder, but the spliced broken corpse will only be a hundred times more terrifying.

What they saw was a humanoid object, like a crushed cookie, and like a three-dimensional puzzle. In particular, the dense stitches that are exposed in some places make this corpse look like a terrifying rag doll with rough workmanship.

"The murderer's corpse dismemberment tool has not changed, there is no obvious difference in the cutting wound wound of each part, the corpse dismemberment tool is very sharp and lightweight, it should be a knife and axe, and it is likely to be a bone chopping knife." Jiang Xiran carefully observed the body surface of the corpse and said seriously.

Zhou Xiaoyi picked up the autopsy record sheet and carefully recorded it on it.

Subsequently, Jiang Xiran carefully examined the two arms of the deceased, and the left arm of the murderer who threw the body in the fitness park for the second time was a corpse piece, but this time it was a complete right arm abandoned at the abandoned construction site.

In other words, the murderer's first two dismemberments showed unusual calmness, but this time the body was thrown in a very hasty and hurry. The cutting of the corpse became more and more sloppy, and it was discarded without even dismemberment.

This is very good news for Jiang Xiran, because she can look for more clues from the body appearance of the deceased.

"In homicide cases, the arm is the most prone to trauma, especially restraint and resistance."

After Jiang Xiran finished speaking, he picked up a magnifying glass again and carefully checked the position of the deceased's fingernails: "If the deceased and the murderer have a fight, there will definitely be dandruff tissue left in the nails." ”

She observed for a while, glanced at Zhou Xiaoyi, and motioned for him to record: "There is dirt in the nails, but there is no residue similar to the stratum corneum of the skin, and there are no obvious defensive wounds on the torso, and there are no obvious fatal wounds. The fatal wound of the deceased should be in the head or neck ......"

Zhou Xiaoyi recorded carefully, then raised his head and asked with some doubts: "Section Chief Jiang, how did you judge that the murderer's tool for dismembering the body was a knife and not an axe?" ”

Jiang Xiran was still inspecting the corpse surface, and said in a deep voice: "In the autopsy process, you can't only focus on observing the corpse surface, but also the cut wound of the corpse is also very important. The wounds of the corpse parts were flat and the body parts were of the same size, indicating that the murderer's dismemberment tool was a small knife. Moreover, in the process of dismemberment, the murderer only processed small and thin bones such as fibula, ribs, metacarpals, and metatarsals, which further shows that the murderer's dismemberment tools were not enough to support him in processing some large and hard bones. ”

Zhou Xiaoyi showed an expression of sudden realization, and hurriedly asked again: "Then how do you judge the bone chopping knife used by the murderer?" ”

"The murderer's professional method of dismemberment shows that he understands the structure of the human body, which is in line with the original judgment of the butcher's profession. And have you just noticed that the section of the severed bone has different degrees of internal bone cracks. This shows that the bones were cut off instantaneously by the action of gravity, and the combination of the two led to the conclusion of a bone chopping knife. Jiang Xiran replied seriously.

Zhou Xiaoyi nodded thoughtfully.

"Alright, let's sort out the autopsy report, I'm going to the criminal police team to participate in the case analysis meeting later. The bureau has issued an order to solve the case within a 24-hour deadline, and the pressure on Lu Ke's side is not small, so we have to find a way to reduce the pressure on him. Jiang Xiran turned on the faucet and carefully cleaned his arm.

But no matter how much you wash it, there is still no way to completely remove the strong rancid smell.

"By the way, is there any news from the laboratory department?" Jiang Xiran suddenly asked.

Zhou Xiaoyi was sitting in front of the computer sorting out the autopsy report, and replied: "Here's the news, after preliminary DNA identification and comparison, these decaying corpse parts and the corpse parts found in the previous two times are the same person." ”

Jiang Xiran raised his head, let out a long sigh of relief, and muttered, "That's good, that's good......"
