What is the story of a major violent attack on a police officer in Huai 'an, Jiangsu?

Wang Tao, a policeman from the fifth brigade of the patrol special police detachment of Huai 'an Public Security Bureau, and An Ye Lei, an auxiliary police officer, died. On the day of the memorial service, citizens came to offer their condolences. "Thanks to your's arrival, every pair of eyes are full of tears and believe in the light." According to reports, the specific process of this case is as follows:

The incident occurred on the morning of July 6th 10. Policemen Wang Tao, Wang Chunkun and auxiliary police An and Wu Jun came to Room 504, Unit 2, Building 29, Banzha Jiayuan Community where Ma lived. The police got the news that the fugitive and Ma stayed here to verify the situation. When the police knocked on the door of Room 504, there were three people in the room, namely Ma, Ma and the 70-year-old paralyzed mother resting on the balcony.

After the police showed their certificates to show their intention, they asked the horse who was cutting vegetables in the kitchen to show his ID card, but the horse refused. Wang Tao warned Ma that he still refused to show his certificate and tried to rush out of the kitchen with a knife many times, but Ma stopped him. 10,21,Ma climbed up the kitchen window and said that if the police came near again, he would jump. "If you push me again, I will jump." In order to ensure the horse's personal safety, Wang Tao persuaded him to remain rational. Seeing that the policeman looked relaxed, Ma asked Ma to give him his mobile phone. After getting it, Ma Hongbing immediately dialed a phone call and shouted, "The motor was arrested." 10: 2 1: 43, Ma Weibing hiding in the community suddenly rushed into room 504 with two sharp knives, "kill you!" These two sharp knives were hidden in the weak box on the fifth floor in advance. Ma Weibing shouted and rushed to the four policemen in the room. The horse in the kitchen jumped down with a kitchen knife and began to chop at four policemen.

The scene in the narrow room was chaotic. Wang Tao blocked the crazy Ma Weibing and saved Wang Chunkun behind him. Ann stopped the horse with a kitchen knife and saved Wu Jun behind her. In the extreme confusion, Wang Chunkun and Wu Jun took up the stools in the house to fight back, and took out the single police equipment to deal with emergencies and sprayed pepper spray. Ma's two brothers made a dash for the door. Wang Tao and Ann Ye Lei fell in Room 504, and one fell on the stairs leading from the fifth floor to the fourth floor. Forensic identification showed that Wang Tao's left carotid artery was completely severed and Ye Lei's left abdominal aorta was punctured. Both wounds were 3.8 cm, and the penetration depth was 12 cm and 10 cm, respectively. Both of them died of excessive blood loss. Although it took only 6 or 7 seconds for the Ma brothers to attack the police, they were fierce, which led to the case.

After the incident, the two brothers fled the scene in a battery car with yellow pedals, carrying a kitchen knife with them and wrapping them in yellow clothes. Finally, in the afternoon 18: 38: 25, the two brothers Ma picked up their knives and tried to resist again. At 39: 30, the two men who struggled in vain were handcuffed. The crazy behavior of the two brothers Ma not only destroyed Ma's family, but also hurt his wife and children, his brother and his 70-year-old mother, and even hurt two other heroic families who were crying and could have been happy.
