"What do you think?" Qin Gang asked.

"The clothes were not pierced, how did the knife get into the abdomen, did he pick up the deceased's skirt and stab it?"

Li Yi repeatedly reviewed the report of the technical team, but found no description of the examination of poisons or narcotic drugs, confirming that the knife wound caused excessive blood loss and death.

His brain spun rapidly, looked at Qin Gang, got up and walked to the whiteboard to pick up the pen, stretched out his hand but didn't write anything, and returned to his seat.

"What kind of ritual does the murderer need to complete? After the murder, the deceased was dressed in this dress to satisfy his sense of ritual. Li Yi said.

"Hey, Brother Yi, your brain is open and unrivaled."

Li Yi patted his head, "There is indeed some brainstorming, and there is no religion-related information at the scene, the corpse was just placed on the sofa, and I can't see what was done to the corpse, so why is this." The deceased suffered from celiac artery blood loss, bleeding a lot, and after changing the dead clothes, he was covered in blood, so did he leave without changing? ”

Killing someone, and then changing the victim's clothes, you have to do something more, otherwise the act is really puzzling.

"The murderer is a pervert who has a paranoid perverted idea about female sexual victims, and the skirt is a piece of clothing that the murderer likes very much, or it was originally given to the deceased by the murderer, and he wants the deceased to die in the dress he sent." Qin Gang also made up an idea in his mind.

The night was as quiet as a pool of water, and only the sound of the alarm clock ticking in the office gently broke through the quiet atmosphere.

"Think about it, think about it again, and open your mind to your heart's content."

This kind of strange modus operandi, Li Yi is the first time to encounter, his profession, will experience all kinds of bloody, terrifying, perverted, and even close to supernatural murder methods in the handling of cases, but today, it makes him feel treacherous.

"Perhaps, they are a couple, the murderer bought this skirt that the deceased liked, and gave it to the deceased in 1503, the deceased was very happy, and then changed the skirt to try whether it fits, and the murderer took advantage of her to change her clothes and killed her with a knife." Qin Gang said.

"Far-fetched, if the purpose of 1503 is to kill people, this method is too complicated. If it is a couple, the deceased has absolutely no defense against the murderer, and there are many easier ways. For example, when you are drugged in a drink, or when two people are warm, or when you can wait until you go to bed at night. The scene is very clean, remember the phrase plum. ”

Alone with the corpse at night, carefully cleaning up the scene, there will definitely be an easier and easier way to kill people that they can't think of, Qin Gang nodded thoughtfully.

"But I think the murderer's purpose in 1503 was to kill people, and the place in Lushan Yijing is far away." Qin Gang clinged to the idea of his deliberate murder.

"I agree with this, because the scene is very clean, and I am thinking, is the murderer male or female?" Li Yi asked a question.

"Why do you think so?"

Li Yi found a pen and held it in his hand, and stabbed from the bottom to the top several times in a row, feeling the power of this action.

"The two should be about the same height, or the deceased was even slightly taller than the murderer."

Qin Gang looked at Li Yi's actions and felt reasonable.

"But how to distinguish between men and women, there is no legal requirement that a boy must be taller than a girl in a couple."

"That's not it, the wound is not deep, I just did this stabbing action, in terms of strength, piercing into the abdomen without any bone protection, as long as the murder weapon is sharp enough, the wound should be relatively deep. According to the analysis of deliberate murder, since you are determined to kill, there is no reason not to be ruthless. But if the force does not penetrate deeply, there are two possibilities, one is that the person really lacks strength, but the normal development of males, as long as there is no disability in some way, this strength must be there; Another possibility is that the murderer is a woman, and she can only go so far if she is ruthless. ”

Qin Gang also grabbed a pen and stood up, and repeatedly made a few upward stabbing movements.

"It feels like we're going to have to think about the murderer evolving into two roles."

"Well, we have to think about one side at the same time." Li Yi said.

"Which aspect."

"Cleaning up the scene, the time of death in the report of the technical team is 14:30-16:30, and it will take 4 or 5 hours to clean up the room with a trace destruction. The celiac artery lost blood and died in about half an hour, and the murderer began to clean up the scene at 14:00 at the earliest. ”

"Cleaned up the site around 18:00." Qin Gang answered.

"Yes, then do he leave right away or wait until the sun goes down and it's dark all around before leaving in the night."

"If it were me, I would choose to leave when it was dark all around, the place was less crowded, and at night, the chance of going out from the community and hitting someone was close to zero, which is also in line with the meticulous thinking of the murderer we set."

Li Yi slapped his face, "That's right, I will choose this too, but this requires staying in the room with the corpse until it gets dark." Cleaning up the scene can be done with only careful care, but accompanying a corpse that changes differently over time in the dark of night requires a different kind of psychological quality. ”

Li Yi looked at Qin Gang, "The miserable white LED light, shining on the miserable white corpse, slowly changes in front of your eyes, and the air begins to slowly fill with an indescribable disgusting smell, can you be at peace with her and ignore her existence?" ”

"Uh...... I don't know, I haven't tried it, but it should be a little chilling to think about that scene. ”

"That's right, ordinary people can't do it, especially if it's more difficult for a woman, I'm a little entangled."

"But the problem of the skirt has not been solved, how did the murderer do it." Qin Gang said.

"At present, it seems that there is really no solution, and the brain hole cannot be opened blindly, so let's solve it slowly."

Li Yi felt that this case was happening right under his nose, No. 7 and Qin Gang finished moving things with a few colleagues, and it was about one o'clock after cleaning up.

They drove to the food street outside the sports school to have two drinks, and walked back to the community at about three o'clock, and he never met anyone along the way, with his professional sensitivity, any person during that period of time, if there was an unusual person in his field of vision, he could still remember it vividly.

"Brother Yi, you said that if we don't go out to eat on the 7th, we will bring some food and drink in your house, will we catch the murderer on the spot?" Qin Gang said suddenly.

"Don't talk in your dreams."

According to the information on the owner's tenant's profile, the tenant Ye Mengyin, 25 years old, female, has a foreign household registration.

It was the age of youth and grace, but he turned into a wisp of fragrant soul in his hometown, drank Meng Po soup and walked across the Nai He Bridge early.

The deceased paid a one-year rent at one time and signed a three-year contract, and should have the intention of staying in Lushan Yijing for a long time, but there was no information about the vehicle she registered in the community.

In such an inaccessible community, if it is a working cluster, you must go out early and return late, maybe you go to work for a day, and half a day will be spent on commuting.

With such a busy life, I'm afraid that there is no time to fall in love, and there are no close people around her, unless she is not at work.

Li Yi carefully recalled everything at the scene, the furniture in the house was relatively simple, and the owner purchased a rental house with furniture, which was probably the case, but there seemed to be an executive suit in the wardrobe, and the grade of the clothes and dresses seen was not low. The rental is not high-end, but the dress is not low-class.

"Give me a call tomorrow, Ms. Lin." Li Yi said.

"I wish you a happy day, I just hung up today, I guess she won't have time to answer us in the past two days."

"It's okay, let's fight tomorrow morning, we have to close the case, we need her to sign, she has a wound on her face and it's inconvenient to go out, let's go to the door, if she is really inconvenient, then make an appointment with her, we always have to give Team Liu a quasi-letter."

"When are you going to write a closing report?"

"Tomorrow before work." Li Yi looked at Qin Gang slyly.

Qin Gang came to his senses, with the case of Lushan Yijing, they have no distinction between going to work and getting off work, in this process, they are only sleepy or not sleepy and tired or not tired, maybe when the murderer in this case is brought to justice, they will be considered off work.

"Team Liu is not easy to fool, or you can write it now, I'll watch the video first, and when it's about time, you can continue to watch it."

Li Yi and Qin Gang divided labor, Qin Gang watched the first half of the night, Li Yi wrote the report first, and changed Qin Gang in the second half of the night.

When Li Yi wrote the report, his eyelids seemed to have begun to fight, Li Yi clearly knew that he was going to say hello to Zhou Gong, so he simply wet the towel with a bucket of water, and when his eyes were about to close, he wiped his face with a towel.

When Qin Gang woke Li Yi up, Li Yi's whole body had almost slid off the chair, and his sleeping position was extremely strange.

"You fell asleep with your head drooping, it looked like you were hanging, I took a photo of you and sent it to Team Liu, saying that you couldn't wake up from a long sleep." Qin Gang said.

"Am I so unbearable? Didn't I watch the footage in the second half of the night? ”

"Mmmm, you slept like a dead pig, but I read your closing report, it's almost, and there are three more sentences and five sentences to end it, and you can finish it after breakfast."

"Then Team Liu didn't say anything when he saw that I couldn't wake up from a long sleep? This can be regarded as a death in the line of duty, and there must be a medal or something. ”

"No, Team Liu said to let you sleep a little longer."

Qin Gang called Ms. Lin, and was very surprised, Ms. Lin didn't mind that they came to close the case at this time.

The two of them drove to Ms. Lin's house, her injuries were not too serious, mainly blood loss and fear, Zhu Happy was discharged from the hospital two days ago, and returned to her parents' house to recuperate.

It was Ms. Lin's mother who opened the door, and she thanked Li Yi for catching the suspect so quickly.

"Yes, it was caught, it was arrested in Guan City, so this case can be closed, Miss Lin is injured and it is inconvenient to go out, so we will come over." Li Yi looked polite.

Walking into the hall, Li Yi's heart fluttered violently, almost jumping out of his chest, and Ms. Lin was wearing a dress with light grass green and a skirt embroidered with lotus flowers, sitting on the sofa.

"Is it inevitable or accidental." Qin Gang said in Li Yi's ear with a sound that was almost mosquitoes buzzing.

"It's fate." Li Yi said.
