Li Yi took the elevator straight up to the 15th floor, came to the door of the scene, and stood quietly for two minutes, his mind blank.

The door of 1503 was sealed, the hallway was dimly lit, and the disgusting stench of the afternoon could still be faintly smelled in the breeze.

"The site was very clean." Meizi's words came out of Li Yi's mind.

Is it really her?

Li Yi recalled the lotus skirt that flashed by the elevator door that night, and had a dreamlike feeling, slowly walking down the stairs and going home.

After a short wash, I poured a few sips of beer and lay down on the sofa to relax.

The scene of this case is too neat, and it is the cleanest of Li Yi's 5-year criminal police career.

From the bedroom to the bathroom, from the kitchen to the living room, the windows are bright and clean, except for the blood stains and histiolytic fluid on and around the sofa, everything else is in order.

If it weren't for the dust on the table in the room, it would be like someone had just finished cleaning and was waiting for Li Yi and them to come to check.

Kill people, clean up the scene, and then calmly escape.

The murderer was calm and had plenty of time, he knew the deceased and knew that she lived alone, so he dared to deal with the scene safely.

He should also be familiar with the surrounding environment and have a good mental quality, otherwise he will not be able to calmly accompany the corpse to clean and tidy up, and he will stay until the dark night.

It only takes 10-15 minutes after a person dies, and the sudden drop in blood flow will make the corpse pale, and the white LED lights will be reflected in the big night, and you will be panicked if you look at it more.

After 2 hours, the cadaveric spots that stimulate the optic nerve have begun to slowly appear.

After 3 hours, as the immune system is completely cooled, the bacteria and fungi in the body are multiplying, and a large amount of pungent gas is produced in the intestines from the mouth, nose, and anus, and the indescribable smell will slowly fill the room.

Six hours later, the corpse was completely frozen and a generalized zombie occurred.

It is necessary to clean up the scene carefully and carefully, although it is a small two-room, but it must take a lot of time, and the murderer will most likely witness the gradual change process of the deceased, which requires a very strong psychology.

In this location, public transportation can only take to the sports school terminal, and then walk nearly two kilometers along the avenue to reach the community.

What kind of transportation did he use to enter the community, how did he leave after committing the crime, the bathroom was empty, all the toiletries were taken away, he should need a bag or box to store these items, and when should he leave the most appropriate.

Li Yi assumes that he is the murderer, carries out the murder, handles the scene, and then may stay until a suitable time to leave, taking away the mobile phone wallet, taking the murder weapon, and all the traces that may have existed.

Take away the bathroom items, yes, he may be a close person next to the deceased.

However, a little girl, what secrets can cause death, her life feelings, the nature of her work, these thoughts are constantly floating in Li Yi's mind.

In the quiet night, under the shadow of the trance lamp, the familiar telephone ringtone, the silence is particularly harsh, the lights of the cordless phone call screen are dazzling, and a string of numbers are suddenly reflected in front of you, which seems to be the same as the last number, but it seems to be different.

Li Yi clearly knew that this was a dream, he wanted to work hard to remember, he worked hard, and wanted to write down the phone number, but the more desperately he tried to remember, the more he couldn't remember it, and he didn't have the smoothness of remembering the phone number in his usual life.

He began to become anxious, convinced that what happened around a person, what happened repeatedly in a dream, would not be for no reason.

He tried to find the pen and paper, but found that in the darkness, he could not see anything, and the lights that seemed to be extinguished just now were all gone at this moment.

While fumbling, he pressed the answer button.

Everything was calm, the walls and lights of the empty house were white, the grass insects chirping downstairs, and the street lamps were dim.

Li Yi walked out of the balcony, and in the sky, a bright moon gently poured moonlight.

He tried his best to think about the call in his dream, but his mind wandered involuntarily with the lotus skirt, which haunted his thoughts tightly in the dark night, Li Yi picked up the package and opened the door and went downstairs as if fleeing.

******

Qin Gang was already in the office, and when he saw Li Yi coming in, he said, "I called you twice, but you didn't answer, thinking that you let Zhou Gong catch you." ”

Li Yi checked the call, there was indeed Qin Gang's number, and Team Liu's number, Team Liu called three times, looked at the mobile phone settings, the loudest ring mode, I couldn't figure it out.

"Team Liu has also beaten, and I can sleep so deeply." Li Yi's mind flashed with a dream of Nan Ke at home.

"Team Liu ordered two suppers for us, and they will be delivered in a while." Qin Gang said.

"I seem to be dreaming all the time these days, so I won't have a nervous breakdown."

Li Yi called up the video from the USB flash drive, and casually handed the USB flash drive to Qin Gang, "You also make a copy, we will divide the labor and look at different time nodes." ”

Qin Gang smiled, "It's not a nervous breakdown, it's that after you asked me if I had a girlfriend to introduce me that night, I started to have dreams." ”

"Well, even if it's you, you introduced people to me and dispelled my dreams."

Together, the two of them first went through the inquest of the scene, the laboratory tests and the results of the autopsy and the corpse bolt of the technical team, and sorted out the basic context of the case.

One: There are no traces of any fingerprints, including the deceased at the scene. Door, bedroom, room kitchen, including wardrobes, drawers...... All the handles in the room were only extracted from the traces of the cleaning aunt, the property manager, and the owner on the door handle, and no other traces of the third party could be found.

2: There are no traces of third-party footprints, the ground on the site has been carefully cleaned and cannot be effectively extracted, only the footprints of the owners and property managers in the corridor.

Three: The bloodstains at the scene belong to the deceased.

Four: The deceased's mobile phone was lost and could not be found at the scene, so call it to turn it off.

Five: Wallets and identification information could not be found at the scene.

Six: All the toiletries in the bathroom are missing.

Seven: The scene is well organized, and there are no traces of fighting.

Eight: The deceased had a wound in the abdomen, the wound was not deep, but the wound was pierced upward from a point above the navel and pierced the celiac artery, and it was preliminarily judged that he died due to excessive blood loss.

Nine: The on-site computer has been initialized by the system, and no traces of use have been retained, and the murderer has certain basic computer knowledge.

Ten: There was no murder weapon at the scene, and from the analysis of the wound, it was a fruit knife commonly used in the family, but the knife head was quite sharp and could be easily pierced into the abdomen, and it was initially inferred that the murderer took it.

Eleven: The deceased is dressed in a dress, but there is no stab in the skirt.

Twelve: The time of death of the deceased is determined to be in the range of 14:30-16:30 on the 7th.

"The deceased was dressed in a dress and there was no stabbing hole?"

Li Yi and Qin Gang both felt incredible, but it was the last point that made Li Yi's back faintly chill.

The time of death determined by the autopsy of the technical team must be scientific and materialistic, Li Yi believes that the idealistic must be himself, but what he saw that night, if it was not a girl in the same dress, then it was most likely a Chinese ghost story.

Li Yi suddenly felt a little chilled.
