Located in the old town of Chunyang City, International Mansion is a place where every inch of land is at a premium, and the unit price of new real estate here is approaching 6 figures. It has one of the best elementary and middle schools in the city.

Many parents do not hesitate to sell iron and buy a house here, just for their children not to lose at the starting line.

According to the information sent by Yanan, Hu Lai, the head of room 2601 in Building B, was 40 years old and 2. She is a Chinese teacher at the No. 12 Middle School in the suburbs, and her 11-year-old daughter is in the fifth grade at the nearby No. 1 Primary School.

How can a Chinese teacher buy this duplex luxury suite with a small garden on the top floor in the center of the city?

It is not surprising that Hu Lai has a capable wife, Qin Fen, who works as a sales director in a pharmaceutical company with an annual salary of 7 figures.

A headshot, it looks like Mr. Hu is quite gentle, which is in line with the temperament of a Chinese teacher.

The time was approaching early in the morning, the community was extremely silent, and when Xiao Mo pressed the elevator up button, the elevator came down from the 26th floor.

On such a night, at such a point in time, the elevator just came down from the 26th floor.

If something really happened to 2601, the elevator came down from the 26th floor at this time, which would be very sensitive.

As a criminal police officer, vigilance is certain. This time, no matter who comes down from above, must be detained first.

I didn't hit the elevator all the way, and went straight down to the first floor, and the elevator was empty.

Xiao Mo couldn't help laughing at himself, not that he was too sensitive at this point in time, but that he was too sensitive!

The door of Room 2601 was opened, and a strong bloody breath rushed straight to the door.

The scene was particularly bloody, Hulai leaned back on the sofa, the milky white sofa was blood-red, and the edges of the sofa were still dripping with bright red liquid.

The scene was very tragic, just like the video footage sent by Yanan, this man's unique thing fell under the sofa.

What is different from the video is that Hulai's ten fingers are broken from the root of the fingers.

Ten fingers were scattered on the floor in front of the couch, and the picture was quite terrifying.

The artery in the neck had been severed, and a bright red fluid was flowing there, from which a large amount of blood had flowed from the couch.

Xiao Mo hurriedly grabbed the sofa towel on the side and tied it to Hu Lai's neck, and the blood couldn't stop seeping out, probing Hu Lai's snort and faint breath.

It's not that I'm too sensitive, but I'm really sensitive at this point in time.

The end time of the live broadcast sent by Yanan was 11:35, and the time he arrived at the scene was 11:56.

What can you do in twenty minutes?

Suppose the murderer went down the stairwell to the first floor in order to avoid elevator surveillance, how long would it take?

This is a classic elementary school math thinking problem, Hulai's family lives on the 26th floor, and it takes 25 seconds to go down each floor, so how much time does it take to get from the 26th floor to the first floor?

(The author is very scummy in mathematics and can't calculate, and he can leave footprints if he can calculate.) ）

While taking out his mobile phone and dialing 120, he turned around and went out of the door and got on the elevator.

If you have enough time, you may be able to meet the murderer on the first floor.

There are no such coincidences in the world, I didn't see any suspicious people on the first floor, but I met a man who came in a hurry, and this girl came at the right time.

"Yanan, don't ask why, now I'll let you climb up the stairwell to the 26th floor to see if there are any suspicious people."

Yanan looked confused, but obediently turned into the stairwell.

The topography of the International Mansion Community is not complicated, because of the plot, there are only two buildings in the entire community.

In the wee hours of the morning, the two AB buildings stood quietly in the night, and only a few houses were still lit up.

The small atrium was also quiet, and half of the shadow was gone.

I asked the security guard at the gate, and the security guard was in good spirits, and he was sure that there were no vehicles and people going out during the time period when Xiao Mo came in.

Is the murderer still in the community? Or did he leave before Xiao Mo came?

The security guard was a little confused and said that there should be none!

He wasn't sure because during that time, he went to the toilet, because he ate a little too much at night, and it was still a plus.

However, he soon found an excuse for leaving his post without permission.

"Officer, there is monitoring in the monitoring room, just check it out."

120 came quickly, and now it is important to save your life.

Xiao Mo said to the young security guard: "Before I come down to look for the surveillance, not a single mosquito is allowed to go out, as long as someone wants to break through the gate, pick up the electric baton in your hand and give me electricity." ”

Hulai's life was in danger that night, and the doctor of 120 came and stayed for less than two minutes, saying that there was no help, and he was evacuated quickly.

After Doctor 120 left, Gao Yanan appeared at the door of 2601 breathlessly, and covered his chest when he saw such a scene.

"My good man, this is really a live broadcast of the murder."

Although it was a holiday, the dedicated trace department, the forensic department came quickly. Each performs its own duties and quickly enters the working state.

Zhu Miaomiao, a woman, usually looks like a big girl, but she is meticulous and neat at work, which is completely inconsistent with her usual sloppy and lazy appearance.

Xiao Meng believes that excluding personal factors, Zhu Miaomiao is really a good female forensic doctor, and she is also worthy of the title of Zhu Yidao.

"The corpse was fresh, the muscles were relaxed, there were no corpse spots and zombies, and the time of death was less than one hour. The cause of death was preliminarily judged to be caused by excessive bleeding from the rupture of the neck artery, and the specific cause of death required further autopsy results. There were no signs of resistance at the scene, and it cannot be ruled out that the deceased had taken drugs such as tranquilizers before being killed. The neck and finger wounds were not neat, and the murder weapon was judged to be scissors or something. The genitals of the deceased were severed, the wound was smooth and neat, and the murder weapon was judged to be a knife such as a flat mouth. ”

No murder weapons such as scissors or fruit knives were found at the scene, and the murderer's modus operandi was clean and clean, except for the shocking blood stains on the sofa and on the ground.

Apart from the cat's footprints, no second suspicious person's footprints were found.

There was no trace of the room being turned over, and some valuable things of the deceased's mobile phone and computer were still there, indicating that the murderer came directly for Hulai's life.

As for why the external genitalia of the deceased were cut off? Murder is nothing more than three categories, financial killing, vendetta killing, and love killing.

In this way, the possibility of murder is relatively large, and it is relatively easy to investigate this kind of case, only from the social relations of the deceased, and the murderer is just around the corner.

The live broadcast at the scene of the crime ended at 11:36 p.m., and it was 11:56 when Xiao Mo arrived.

The final scene of the crime is compared with the last picture of the video, and the last picture of the video is only blood stains on the sofa seat and the floor. At the final crime scene, there were a large number of blood splatters on the back of the sofa, on the wall behind the sofa, and on the ground.

This shows that the murderer cut off Hu Lai's external genitalia before the live broadcast began, and Hu Lai was in a coma for the entire more than two hours of live broadcast.

And the murderer committed a deadly crime against the victim only after closing the live broadcast room.

In other words, the killer inflicts the final assault on the victim and escapes within twenty minutes.
