There was a case of no way in the city center, and all six members of the family were killed except for the elder sister and younger sister, and the scene was horrific. The father fell to the ground, with multiple stabs in the back and neck, a major artery in the neck severed by a critical blow, and a blood-colored swirl pattern on the wall, as if there was a religious standard. The mother's body was lying on the bed, with a deep wound on the neck, no sign of resistance, as if dead in a dream, blood still dripping down her hand. The eldest son was also stabbed to death in his own bed, and there was a swirl pattern on the mirror. Through the reflection on the mirror, the fourth body was found, it was the youngest son, who was lying on the side of the bed and stabbed in the back, and there were two bloody handprints on the wall, which looked very strange.

Lao Ji was puzzled, why did the murderer leave only the two sisters and not do it? Is it pity for the fragrance and cherish the jade? He came to his sister, who was only concerned about when she could be with her sister, and the sister must have been terrified. Lao Ji came to his sister again and asked her if she was frightened, but her sister remained silent and refused to say anything. Just as Lao Ji turned around and was about to leave, his sister said a word "hand cow", and then said nothing. Lao Ji went to the scene to investigate again, and he came to the kitchen, which was the only place where there was no blood. The kitchen cupboard where knives were placed was opened, and a knife was missing. It seems that the murderer was very familiar with the house.

By the next day, the reconnaissance team had uncovered more clues. There were tire marks in the yard, a smoked cigarette among the flowers by the door, and an unburned match next to the flowers. Sister Xi sampled the bloodstains in the house and believed that the murderer was not a cult. She had studied the scene of a cult murder, and those patterns were just smoke bombs used to mislead them. Lao Ji decided to start with the word "hand cow" to figure out what it meant. So Lao Ji interrogated his sister, and her sister confessed that she heard a noise from the kitchen. She was scared and hid in the cupboard. Lao Ji asked her if she knew the word "hand cow"? My sister was puzzled and said she hadn't heard of it. On the other hand, Mira is helpless against her sister, and when Mira compliments her on her beautiful drawing, she immediately paints it off and pickles her ears, and she seems to be disgusted by the compliments of others.

Ah Wei and Xiao He investigated the traces in the yard, and he investigated the automatic sprinkler device in the yard, which will automatically sprinkle water at 2 o'clock every night, so these traces are newly left. Xiao He guessed that someone left the house at night and drove across the lawn on a motorcycle. Sister Xi marked every place of the bloodstains in the corridor of the house and took photos to record them. She's speculating on the killer's path to kill. The murderer was the first to kill her mother, who cut her major arteries with a knife while she was sleeping, and the mother did not struggle, which explains the mother's blood flowing on the bed. The father, who was sleeping next to him, was awakened and wanted to run out to protect his child, but the murderer slashed him several times in the arm and chased him all the way, finally finishing the father in front of his sister's door.

In the police station, Xiao He reported to Lao Ji that he had investigated the model of the motorcycle and found that it was a 93-year-old Honda motorcycle, and a man was found in four blocks with the same model of motorcycle. But Lao Ji is more concerned about another thing, after a normal person is killed, he will definitely check the body, but the clothes on his sister's body have no blood stains at all, and he is very puzzled. Xiao He found the owner of the motorcycle, and the man said that he was not in the city at the time, and that the motorcycle was bought with three other friends, and he also revealed that his sister lived an inappropriate life and had relationships with many men.

Mira returned to the police station, and everyone summed up their findings: Xiao He said that a car tire trace found four suspects. Lao Ji said that the pajama pants that his sister wore that night had no blood stains at all. They were about to interrogate their sister again when Ah Wei found a cigarette in front of the house. According to my sister's confession, no one in their family smokes, and this cigarette is usually smoked only by young people. Mira said that her sister has catatonic disorder and is recovering from trauma, and that she has a strong reaction to the word "buffalo", which she is visibly scared when the word is mentioned.

Lao Ji and Sister Xi interrogated her sister again, and the sister insisted that she witnessed the death of her family, and she ran to the neighbor's house for help, and this is the truth. Lao Ji said slowly, but the evidence at the scene proves that you are lying. On the other side, Ah Wei was interrogating the three suspects of the motorcycle, and the last man exposed his flaws, and he was about to smoke but was stopped by Ah Wei. The man's match was also confiscated by Ah Wei, and the sheriff identified the suspect who was most likely to kill and prepared to apply for a search of his home. My sister panicked, she asked to see her sister, Sister Xi refused, and asked if it was her boyfriend who killed her family, and my sister was silent again.

Ah Wei returned to the laboratory to verify the match stem, and found that it was exactly the match found by the flowers. On the other side, at the man's house, the sheriff and Lao Ji also found the disassembled motorcycle and blood-stained pants. It proves that this man went to the crime scene that night, and he is the murderer. The police station interrogated him by polygraph, the murderer waited in front of the door until two o'clock, he smoked a cigarette on the way, his sister opened the door and put him in the house, they came to the kitchen sister opened the cupboard and asked the man to choose a knife and start the murder.

Man on mom who kills his sister. The father and his two sons confessed to the facts, although the murderer was him, but the electrocardiogram and breathing during his interrogation proved that he was lying. Lao Ji decides to find out their motive for killing and find out their hidden secrets. Lao Ji got all the belongings of the deceased from the forensic doctor, and he found a necklace, and the necklace of his father was a buffalo. He immediately asked Mira to take a picture of her sister to check for signs of X abuse. Here, Sister Xi speculated about the murderer's route and the order of the murder through the photos of the bloodstains and the location of the body at the scene. But when she got to her father's location, she found that the blood droplets did not match her previous assumptions. Dad came out of his sister's room, and the first person the killer killed was Dad, and then he went to kill Mom. And the blood on the floor was dripping from his dagger. The photo came out, and it was clear that someone had abused my sister. So they asked their sister, who looked at her picture and felt a heart-rending pain. She said it was the last night, and Lao Ji asked her why she wanted to kill the rest of the family? My sister told the truth painfully.

Nightmares began when she was very young, and her mother turned a blind eye and allowed her father to bully her. When she was 13 years old, her mother had a younger sister, and as her sister grew up, her father also stretched out his claws to her, and she couldn't bear it anymore, so she teamed up with her boyfriend to kill the whole family. That's why my sister is very worried about her sister's condition and asks to meet at every opportunity. My sister said that she didn't blame her sister for hating her in the future, but the only thing she could do was to protect her sister in this way. Mila accompanies her sister in the hospital, she shakes her sister's hand, and her sister smiles at her, but what will her future fate be....
