Looking back on the massacre, mother and daughter were killed overnight. What is the truth?

On May 20th, Zaozhuang City Public Security Bureau received an alarm, and someone was killed in Zaozhuang Road Village, Shandong Province. After receiving the report, the police quickly arrived at the scene. The crime scene is located in the north of Lu Cun yard, two rows of houses. The police first found the bodies of two naked women, both of whom were tied up from behind by wires. The deceased were sister Wang Erni and sister Wang Xiuyun. Her sister showed signs of sexual assault. On the inner thigh, the police found spots in the body of a suspected murderer. My sister was directly punched and completely disfigured. The police searched carefully for clues left by the murderer at the scene. To Wang Xiangkun's headache, the murderer seems ready. ?

Almost all the items on the scene are his tools for committing crimes, such as scissors, electric irons, hammers, pickaxes, etc. However, with so many crime tools, the police only found the fingerprint of a broken right index finger and some blood, but these cannot be used as evidence. Upon inquiry by the villagers, the deceased had a family of four. One of them, Mr. Wang, was working outside, and there were only two sisters and mothers at home. Now, two sisters have been murdered. Where is the mother of the deceased? The deceased lived in two rows of quadrangles, so the police searched one by one and finally found that the mother of the deceased died of rage in a room. The police investigated the scene again. This time, the police found weapons and bricks, but still failed to extract valuable clues. ?

However, the police found that the room was ransacked except for a small sum of money on the table. The police think this is a robbery and murder case. However, cautious Wang Xiangkun found a burnt passbook of 50,000 yuan in the corner, which overturned the previous hypothesis. Based on the fact that only one of the two sisters was sexually assaulted, the murderer beat her sister with a blunt instrument to disfigure her face. This may be a tragedy caused by love. There was no clue in the on-site investigation, and the police used police dogs. Although the murderer deliberately deleted his own evidence, he could not escape the search by police dogs. Soon, the police dog took the police to a broken house not far from the crime scene. ?

The police mobilized quickly, but the murderer was not found in the house. On the contrary, I found a pair of bloody trousers on the bed and the words "I love Wang Erni and I hate you" hung on the wall, which also confirmed Wang Xiangkun's previous guess. The police learned that the person who lives here is Yu, a villager in the village. Although I am suspicious, where is the other party now? The police are once again in chaos. At this time, when he returned home in February, the police were very surprised and arrested him soon. After the police questioned him and found bleeding trousers in his home, Yu admitted that he was responsible for the murder and explained the crime in detail, which was almost the same as the police investigation. However, careful Wang Xiangkun noticed this question.

According to Yu, he strangled his mother and son, who were beaten to death by blunt instruments. Technicians found that the fingerprint extracted at the crime scene is incomplete, but it can be regarded as a seal pattern, which was punctured in the rest. At this time, Yu suddenly changed his confession, denied that he was responsible for the murder, and sent another message to the police. Wang Erni also had an emotional entanglement with another man named Wu Zhongwei, so the police quickly visited and investigated, and finally found Wu Zhongwei's residence, but the building was empty, but the police found some hairs. After comparing and looking for the crime scene, they found that he was the same person, which indicated that the man was suspected of committing a crime. ?

However, technical constraints at that time failed to find decisive evidence, and Wu Zhongwei could not find his hiding place. The police never gave up the choice of looking for the murderer. Finally, this point at the crime scene was compared with the DNA extracted from Wu Zhongwei. There is a DNA database named Li Hua in the DNA database of the Ministry of Public Security, which is exactly the same. The police quickly arrested him, and Wu Zhongwei finally admitted that Li Hua was the person he later renamed, and he also admitted his crime. Finally solved the unsolved case of 14. Skynet has been restored, no one cares, no leaks. Time may wash away the evidence of crime, but it cannot erase the coming of justice. ?
