/kloc-0 On June 9th, 0, a major criminal case occurred in Inner Mongolia, resulting in 3 deaths and 2 injuries. The cause of the case was that a villager in Heilanghao Village, Wuchuan County, Inner Mongolia lost a sheep, which was suspected to be done by his neighbor Wang, and they had a dispute. Neighbors found that their quarrel was particularly fierce and called the police. After receiving the alarm, the local police station immediately rushed to the scene to investigate and adjust. Moreover, the village cadres rushed to the scene to cooperate with the police to fully grasp the matter and put forward a better solution. However, the horse that lost a sheep felt unreasonable and refused to accept the solution proposed by the police and village cadres. The final adjustment was fruitless. The excited horse suddenly took out his knife and stabbed his neighbor Wang. The police saw that the situation was wrong and rushed forward to stop it, but at this time Ma was out of control. In desperation, he threw the policeman to the ground with a knife. After the police fell to the ground, he threw his neighbor Wang to the ground. At this point, Wang did not stop and stabbed the other three people present. Among these three people, one was dead when he was taken to the hospital. This incident caused three deaths and two injuries. Ma, who is currently committing crimes, has been detained by the police for further investigation. The police informed the case, and Ma confessed to the facts of the murder. The cause of this serious criminal case turned out to be a tragedy caused by the loss of a sheep. Sometimes, people's emotions are easily intensified, which makes people act impulsively. This tragedy is not entirely due to the loss of sheep, but more to the communication between people. Sometimes we will find that many major events are caused by trivial matters, and most of them have serious consequences because people feel wronged, which will distort people's psychology and make people unable to control their behavior calmly when their emotions are out of control.
