Criminal Investigation Notes

Lu Junchi brought Su Hui out, and the two of them walked into the Bijian building on the side, and then went up to the forensic room.

Today is rare, Director Shang is here.Director Shang led the two of them into the dissection room.

After the two corpses were pulled over, they were dissected again.

The perennial temperature setting in the dissection room is low, the room is completely enclosed, there is no natural light, and it is equipped with two super-suction ventilation devices. Even the smell of corpses can be lightened here.

At this time, two white corpses were placed on the two dissecting tables. The lights on the top were shining, and all the details were clearly visible.

The corpses, a man and a woman, were Lu Qin and Ye Zhixue who were killed a few days ago.

Lu Qin's hair was disheveled lying on the dissecting table, her eyes were still slightly open.Ye Zhixue on the side had already died, and his body was pale.

A few days ago, this young couple was still living together, living a happy and harmonious life.

But at this moment, they were already cold, with Y-shaped anatomical marks on their bodies.

Su Hui put on gloves, and when he got closer, he could see clearly that several wounds were knife wounds on their thighs, arms, and chests. Due to excessive blood loss, the two corpses had almost no plaques.

Shang Qinghan has been a forensic doctor for so many years, but he has never seen any kind of corpse. He adjusted his glasses and said, "The male has two club wounds on his head, and the two victims' hands have signs of being tied up, and their mouths were once tied. Restricted, this method of restricting their mouths allows them to speak without shouting loudly, after they were injured and weak, the robbers helped them cut off the restraints."

Lu Junchi asked, "When did you die?"

"According to the contents of the stomach, the exact time of death of the two people was around midnight, which means that the murderer tortured them for three hours."

Su Hui's expression was still very calm, and he looked carefully at the two corpses: "The murderer's purpose was not to rob, but mainly to kill."

Shang Qinghan nodded in agreement: "The place where the murderer cut the knife first was on the leg, the arm and other non-fatal parts. The last knife is the fatal wound."

Su Hui hummed: "The last knife is like an execution..." Especially on Lu Qin's body, the wound of the last knife was very neat, and he could even feel the joy of the murderer's last knife.

Then Director Shang said, "I read from the report of the branch office that it was the deceased's colleagues who discovered that they did not go to work to report to the police, so the two bodies were discovered in time and they were well preserved. These wounds were made when the deceased was alive. Formed, without any trace of post-mortem invasion. Once the wound appears, there will be bleeding, oxidation, infection and other phenomena. The wounds that are separated by more than a period of time can be distinguished in sequence. I can rank you according to the amount of bleeding. A sequence of wound formation."

While talking, Shang Qinghan pasted some signs under the wound.

The sequence of piercing the wound is more helpful for them to restore the facts of that night.

Su Hui frowned, looking at the sequence of the wounds. Such scars showed that the killing was done step by step, from the wounds on the limbs to the chest at the end.

Lu Junchi looked at the autopsy report on the side, thanked him, and asked, "Director Shang, have you found any details?"

You know, Director Shang Qing Hanshang is the first knife here at the General Administration. His basic skills and insight are many times stronger than those young forensic doctors.If he could provide some details, he would be able to let them know more about the murderers.

Director Shang said: "I discovered some circumstances that are different from ordinary cases. These two victims were killed almost at the same time, and died by different murderers."

Hearing this, Su Hui frowned even tighter, and Lu Junchi also stopped and looked over.

Director Shang further explained: "The murderers thought they lost the knife and wiped out all traces without leaving fingerprints, but they didn't know that the wounds on the corpse had already revealed a lot of information. Everyone's knife The techniques are all different, whether the knife is held with the left hand or the right hand, when holding the knife, whether the murderer’s thumb is turned outward or inward, how much force is used, and what direction is, all of which will affect the stab wound.”

Lu Junchi nodded convinced when he heard this: "So even if different murderers use the same weapon, they will have different wounds. I heard that experienced forensic doctors can distinguish the similarities and differences."

Shang Qinghan heard that the phrase "experienced forensic doctor" was very useful, and continued to explain to them: "The knife marks made by skilled killers can be identified like fingerprints. Take the wounds on these two corpses as examples. It is said that the knife wounds on women are sharp, pierced crisply, and extremely deep, while the wounds on men are relatively shallow, with sawtooth and friction traces of repeated force."

Lu Junchi bent down and indeed found some differences in the traces of the wound.

Shang Qinghan concluded: "So, based on the wounds on these two people, I can boldly speculate that they were killed by different people. The male murderer may be a female murderer or a juvenile killer, while the female murderer was a male. A young murderer."

Lu Junchi nodded: "According to the on-site investigation of the physical examination, the body was found in a different room and there was no trace of movement. Witnesses in another case also said that there were three culprits."

Su Hui linked a lot of information. Generally, among multi-person organized crimes, there will be a clear division of labor. For example, women will be engaged in more skilled and meticulous work, and most men will be engaged in violent work.Such two corpses and such death conditions made the case more complicated and confusing.

Looking at the two corpses, Su Hui could feel a kind of pain, which came from those wounds and their unwillingness.

What happened that night...

"In short, these are the main information that the corpse can provide, and I have written the rest in the report." Director Shang looked at Lu Junchi and said, "The rest of the secrets are for you criminal police to investigate."

It was the afternoon off-duty time, and Aunt Zhang was shopping for groceries in Huadu's Xinmao Community as usual.

She met a short-haired woman at the gate of the community. Aunt Zhang had seen this woman twice when she went in and out of the garbage, and knew that she was a new neighbor who moved to the opposite door.

At this time, the two entered the community together, and Aunt Zhang greeted them warmly and said, "Oh, you just came back from shopping."

The short-haired woman didn't seem to expect that Auntie Zhang would talk to her, and she was stunned for a second before returning to her: "Yes, Auntie."

Seeing that Aunt Zhang was carrying two bags, the woman stretched out her hand and said, "Auntie, you bought so many things? Let me carry some for you."

Aunt Zhang did have a bit of a hard time carrying it here. Seeing that she took the initiative to carry it, she passed a bag to her by borrowing the donkey field down the slope: "Oh, that's so embarrassing, little girl, you are so filial. If my daughter has half as much heart as you, It won't be all my wife who is busy."

The woman just smiled shyly, helped her get things, and walked into the community.

"Oh, girl, what's your name?"

"My surname is Mi, and my name is Mi Shu."

"Well, that name is not common."

"What do you do for work?"

"I'm a programmer."

"Well, it's rare for a girl to do this job, it must be a lot of pressure..."

"It's okay, I'm used to it."

"I think you leave work quite early..." the old aunt asked gossipingly.

"Oh, I recently resigned, and the tutor my son is looking for to study art is here in Huadu."

"The big one in your family is your son... I can't even see how you have such a big son at such a young age."

"It belongs to my husband and ex-wife..." Mi Shu added.At this point, she has quickened her pace, and she regrets talking to this aunt a little bit. It's like checking the household registration, asking endlessly, and after telling a lie, she needs to make up for it with a second lie.

Fortunately, Aunt Zhang didn't continue to ask, otherwise she would have to make up another tutor. The two chatted casually about the price of vegetables, and finally reached the stairs.

Going up to the third floor, Aunt Zhang took the bag and said, "Oh, thank you so much."

Mi Shu said: "It's nothing, it's just a matter of little effort."

Aunt Zhang said politely again: "Come play later."

Finally they entered the house, and the world was finally quiet. Mi Shu let out a long breath and put the vegetables he bought on the dining room table.

The house has two bedrooms and one living room. This is an old community, there is no elevator, and the interior is also very old. All the furniture has an old yellow color of inferior wood.

The indoor windows are not big, and the lighting is even worse. At this moment, the curtains in the room are half drawn, a man in black is sitting in front of the window, and a teenage boy is lying on the sofa, holding a mobile phone horizontally, play games.

The man in black turned his head to look at Mi Shu with some displeasure: "I saw you talking to the aunt at the opposite door just now."

Mi Shu rolled up his sleeves, his heart was pounding, "It's just a casual chat."

The man's voice was hoarse: "If she hears something and becomes suspicious, all of us will be in danger."

The teenager lying on the sofa just finished a game, put down his phone and said, "Don't go shopping for food in the future, the same goes for takeaway."

Mishu said tremblingly: "But I think cooking by myself will be more like a home..."

For a while, when the word "home" was mentioned, everyone fell silent.

Mishu added, "You don't need to do anything."

She took the initiative to undertake all the housework. She came to buy vegetables, wash vegetables, cook, wash dishes, and clean up the house.

She is meticulous and patient and cleans here every day.

Just like every time, she will carefully clean the site, wipe off all the fingerprints and footprints one by one, and gather up the leftover fruit cores and cigarette butts.

When she does these things, it's like every time she finishes running the program, she carefully checks every statement and finds every BUG.

Mi Shu boldly continued: "And I think if everyone stays away and doesn't communicate with people normally, it will make people more suspicious."

The air in the room seemed to be frozen, and the man in black finally compromised: "Okay, you take care of yourself. I don't want to make extra trouble."
