Criminal Investigation Notes

Lu Junchi took Su Hui out, and the two walked into the Wujian Building on the side, and then went to the forensic room.

It is rare today that Director Shang is here. Director Shang took the two of them into the autopsy room.

After the two corpses were pulled over, they were dissected a second time.

The temperature in the autopsy room is set at low temperature all the year round. The room is completely closed, there is no natural light, and it is equipped with two super-suction ventilation devices. Even the smell of the corpse can be lightened here.

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

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

Lu Qin, who was lying on the dissection table, had messy hair, and her eyes were still slightly open. Ye Zhixue on the side had long since 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 stab wounds, on their thighs, arms, and chests. Due to excessive blood loss, the two corpses had almost no corpse spots.

Shang Qinghan has been practicing medicine for so many years, and what kind of corpse has never been seen before, he adjusted his glasses and said, "The male has two stick wounds on his head, and the two victims have signs of being bound by their hands, and their mouths were once wounded. Restrained, this method of restraint allows them to speak without shouting, and after they were injured and weak, the robbers helped them cut these restraints."

Lu Junchi asked, "When is the time of death?"

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

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

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

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

Then Director Shang said, "I read the report of the sub-bureau that it was the deceased's colleague who discovered the police that they didn't report to work, so the two bodies were discovered in time and were well preserved. These wounds were made when the deceased was alive. There is no trace of post-mortem violation. Once the wound appears, there will be bleeding, oxidation, infection and other phenomena. The wounds that have been separated for more than a period of time can be distinguished in succession, and I can arrange them for you according to the amount of bleeding. An order of wound formation."

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

The order in which the wounds were pierced helped them restore the facts of the night.

Su Hui frowned and looked at the order in which the wounds were formed. Such scars showed that the killing was gradual, from the wounds on the limbs, and finally to the chest.

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

You must know that Director Shang Qing Hanshang is the first knife in the General Administration. His basic skills and insight are many times stronger than those of the young forensic doctors. If he can provide some details, they can let them know more about the murderers.

Director Shang said: "I found some cases that are not the same as ordinary cases. The two victims were killed almost at the same time, by different murderers."

After hearing this, Su Hui's brows furrowed even tighter, and Lu Junchi also stopped to look over.

Director Shang further explained: "The murderers thought that they lost the knife and left no fingerprints, so they wiped out all traces, but they didn't know that the wounds on the corpse had already revealed a lot of information. Everyone's knife used The techniques are all different, whether the knife is held with the left hand or the right hand, when holding the knife, whether the killer's thumb is clasped outward or inward, how much force is used, and what direction is used, all of which will affect the stab wound."

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

Shang Qinghan heard the phrase "experienced forensic doctor" very useful, and continued to explain to them: "The knife marks stabbed by skilled killers can be identified like fingerprints. Take the wounds on these two corpses. It is said that the stab wounds on the females are neat, the stabs are crisp and deep, while the wounds on the males are shallower, with repeated force serrations and friction marks from the second force."

Lu Jun lowered his body low and did find some differences in the marks of the wound.

Shang Qinghan concluded: "So, based on the wounds on these two people's bodies, I can boldly speculate that the people who killed them were different people. The men who killed the men might be female or juvenile killers, and the men who killed the women were men. A young murderer."

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

Su Hui has linked a lot of information. Generally, among many organized crimes, there will be a clear division of labor. For example, women will be engaged in more skillful and meticulous work, while men are mostly engaged in violent work. Such two corpses and such a death situation make the case more and more confusing.

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

What happened that night...

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

It was the afternoon off work time. In the Xinmao community in Huadu, Aunt Zhang went home shopping as usual.

She met a woman with short hair at the gate of the community. Aunt Zhang had seen this woman twice when she was going in and out of the garbage, and she 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 warmly and said, "Oh, you just came back from shopping."

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

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

Aunt Zhang really had a hard time carrying it here. Seeing that she took the initiative to lift it up, she handed her a bag with a donkey: "Oh, I'm so sorry, little girl, you are so filial, if my daughter is half-hearted by you, It won't be all my wife's busyness."

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

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

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

"Well, this surname is unusual."

"What kind of work do you do?"

"I'm a programmer."

"Oh, it's rare for a girl to do this kind of work, it's a lot of pressure..."

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

"I think you get off work quite early..." the old aunt asked gossip.

"Oh, I recently left my job. The tutor my son is looking for is in Huadu."

"That 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's from my husband and ex-wife..." Mi Shu added. At this point, she has quickened her pace, and she regretted having a conversation with this aunt. It was like checking her hukou, asking endless questions. After one lie was told, she needed to make up for it with a second lie.

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

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

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

Aunt Zhang said politely, "I'll play later."

Finally, they each entered the house, and the world finally became quiet. Mi Shu let out a long sigh of relief and put the food 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. 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 time, 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 his mobile phone horizontally, play games.

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

Mi Shu rolled up his sleeves, his heart pounding: "Just chatting casually."

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

The teenager lying on the sofa just finished a game, put down the phone and said, "Don't go grocery shopping in the future, it's the same with takeout."

Mishu said in a trembling voice: "But I think that cooking by yourself will be more like a home..."

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

Mishu added, "You don't have 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 the place every day.

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

She does these things as if every time she runs the program, she carefully checks every statement and finds every bug.

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

The air in the room seemed to freeze, and the man in black finally compromised: "Okay, you can control your senses. I don't want to make extra troubles."
