What are the creepy real cases in history?

Early in the morning, Chen Fei came to his grocery store with a thermos bucket of porridge. Strangely, the grocery store hasn't opened yet.

Chen Fei has just turned 40, and his wife, Wang Lan, suffers from severe gout, which makes her unable to move around and almost never leaves home. The grocery store is the only source of income for his family. During the day, Chen Fei looks after the store. Her 68-year-old mother takes care of Wang Lan at home, and her mother delivers lunch and dinner to Chen Fei.

Every night after closing time, my mother sleeps in the shop and Chen Fei goes back to live. This is not to say that Chen Fei is unfilial, leaving her old mother to keep the shop and go home to sleep in a big bed. Old people sleep lightly and wake up easily. Chen Fei helps Wang Lan urinate at night, and Wang Lan sometimes groans in pain, which greatly affects his mother's sleep.

Mom usually opens the door at 7 o'clock in summer, and it will dawn later in winter, but it will not exceed 8 o'clock. On this day, Chen Fei time is 8: 30, and my mother has never opened the door so late.

Chen Fei opened the shutter door with a key, and suddenly found blood everywhere on the ground. Her mother fell in a pool of blood and nothing happened.

After the criminal police arrived, it was confirmed that this was a vicious robbery case. As the Spring Festival was approaching, many people who went out to work came back, and the news spread quickly, which had a bad social impact and made people panic.

Public security organs at all levels attach great importance to it, on the one hand, strengthening personnel visits, on the other hand, further improving on-site investigation and evidence collection. However, Chen Fei and its neighboring countries did not provide clues to solve the case, and only the fingerprints of the suspected suspects were extracted at the scene.

The case is deadlocked. Although the county public security bureau and the town police station have pursued the case many times since then, there has been no new progress.

Until 15 years later, Rongcheng police extracted the fingerprint and DNA information of the perpetrator when handling a traffic accident case and entered it into the information base. Unexpectedly, they found that their fingerprints were successfully compared.

After the Ministry of Public Security started the construction project of illegal personnel database, local police entered the fingerprint and DNA data of illegal personnel extracted from previous cases into the system as required. Of course, the police in Chen Fei's hometown police station also did this work. It was this move that made the robbery and murder case of 15 abscond surface.

After investigation, Li, a primary school student who had a traffic accident, was unmarried and short stature. His hometown is in the same place as Chen Fei, and he went out to work as a teenager. He only goes home for a period of time every Spring Festival.

Lee's situation is more in line with the killer. The police conducted a surprise interrogation on him, and his psychological defense line soon collapsed.

Before the Spring Festival that year, Li returned to his hometown and went to the grocery store to buy cigarettes. He thought Chen Fei had been sold to him at a high price, but he didn't point it out at that time (so Chen Fei never thought it would be him). Afterwards, he became increasingly dissatisfied and decided to go to the store to steal things at night.

In the middle of the night, Li took the fruit knife at home and went to the grocery store. He is short and came in from ventilation window. When he was stealing, Chen Fei's mother found him. The old lady stopped him and shouted for help. Li was afraid of being heard by the neighborhood, so he stabbed the old lady with a fruit knife, causing her to bleed to death. After the murder, Li stole hundreds of dollars in cash from the store and ran away.

For many years, Li has been living a life of fear outside, and he is afraid to get married. He admitted to the police that he could finally have a good sleep now.
