The man turned on the faucet, and what flowed out was not clear water, but bright red water, and the air was filled with a very strong fishy smell, and the man reacted instantly, this is blood water.

The police went to the top floor and opened the water tank to find a female corpse floating on the water. Blood stained the whole box of water, and after the water was drained, the body was revealed, her name was An Ying, and she was the front desk of this building.

She had a long, deep cut on her forearm, and a shard of glass was found in it. The officers found a footprint in the flower bed next to the tank and made an inverted mold.

Officers learned that the building did not have a good reputation, with six people mysteriously dying in the building over the past decade, and many felt that the building was cursed.

An autopsy was performed by the court, and the cause of death was undoubtedly drowning, but there was a pinhole in her chest, most likely the killer injected an anesthetic and then thrown into a water tank in a coma.

An Ying's arm wound was two centimeters deep, and the radial and ulnar arteries were severed, causing massive bleeding in the arm. In other words, even if you don't drown, you will die from excessive blood loss.

The water in the tank was also stained red because of the wound, and the police checked An Ying's home and found a bloodstain on the door frame, while in the trash can, there was also a bouquet of flowers and toilet paper.

Upon examination, the blood stains were from the building director, and there were droplets left in the trash can, but the DNA of the toilet paper was another man's. The conversation was known that the supervisor was An Ying's boyfriend, and they had been together for a year and a half, but the supervisor only learned a few days ago that An Ying had been married and had a daughter. But because custody was awarded to the father, the supervisor treated it as if he did not have the child. smiled and chose to forgive An Ying, but then he found toilet paper in the trash can, which was still used.

The director was dissatisfied and planned to argue with An Ying, but An Ying pushed him out of the door, and his hand was caught by the door, and the blood stains were left like this.

The toxicity test results came out, and An Ying's body contained more than the normal dose of M coffee, M coffee is addictive, and ordinary people can't get so much.

The inspection found that the glass in An Ying's arm wound was the stained glass of the building. This glass is available on every floor of the building. Officers went floor by floor and eventually found broken glass at a doctor's home.

Officers searched the closet and found a large box of M coffee and a shoe with dirt soles. The examination revealed that the DNA of the toilet paper was the doctor's, and the doctor's shoes also matched the shoe prints on the flower bed on the roof.

Now all kinds of evidence point to the doctor, he must have something to do with An Ying's death, this doctor is still a Y gentleman, he has a withdrawal reaction under high-pressure interrogation, shortness of breath and sweating.

The police speculated that An Ying was the doctor's lover, but An Ying wanted to turn positive, so she forced the doctor to leave his wife, so the two fought in an argument, and then the doctor injected An Ying with M coffee, and finally threw her into the water tank.

But the doctor flatly denied it, saying that he had been in the hospital for the past two days and had not returned home at all. The police officer had a doubt, if An Ying was really killed by the doctor, then why did he keep his shoes and not throw them away.

The police put on the shoes of a doctor and used a simulation experiment to reconstruct the process of throwing the body. The comparison found that the shoe prints caused by the experiment were one centimeter deeper than the shoe prints found at the scene.

This is far beyond the standard error of the experiment, and Lao Ji found that the murderer's shoe print curve was very strange, his heel was very forced, and his toes were barely forced, which was like a child wearing an adult's shoes.

Lao Ji checked further, and he found a cyan yarn inside the shoe, and An Ying was wearing cyan socks. The officer carefully studied all the cases that had occurred in the building, and he found that in one case, the doctor's name appeared.

At that time, there was a girl who choked on food, and the doctor happened to be at the scene, he performed cardiopulmonary resuscitation on the girl, but because he took medicine, he pressed too hard and broke her ribs, causing the girl's ribs to break her heart, resulting in the girl's death.

And this girl is An Ying's daughter, it turned out that she was not sentenced to her father, but was killed by the doctor, but the doctor was not punished in any way.

Now that the whole case has become clear, An Ying decided to take revenge on the doctor after her daughter's death, she came to the front desk of the building to apply for a job, seduced the supervisor step by step, and made her infatuated with herself, in fact, the real purpose was to get the key to the supervisor, so that she could enter and exit the doctor's house at will.

Under the long-term monitoring, An Ying figured out the doctor's life rules, understood his living habits, knew his interests and hobbies, and finally the time was ripe.

An Ying first stole the toilet paper used by the doctor, put it in her home, then put on the doctor's shoes, left shoe prints in the flower bed, and then returned to the doctor's house, injected herself with M coffee, broke the glass and cut her arm, and finally climbed into the water tank and jumped into it, embellishing the suicide as murder, so as to frame the doctor.

Maybe in her heart, the moment her daughter died, An Ying, as a mother, also went with her. All that is left is a shell that lives for revenge. She was able to endure it until today, all because of the belief in her heart, and she could not be relieved until the moment she jumped into the tank.

I guess she never thought that her seamless plan would be detected by the police, and the ultimate goal would not be achieved...
