What are the famous murders in history?

1, the red pill case. It is one of the three major cases in the late Ming Dynasty. In the first year of Taichang (1620), Emperor Taichang was seriously ill, and Li presented a red pill, calling himself an elixir. Taichang died after taking it. Some people suspected that Zheng Guifei had instigated the poisoning, and immediately launched a series of actions to trace the culprit. In the meantime, party struggles and personal grievances were mixed, and many people died of sin. 2. The beating of the case took place in the 43rd year of Wanli in Ming Dynasty (16 15). At that time, Queen Zongshen had no children, Wang Gongfei gave birth to Chang Luo, and Zheng Guifei gave birth to Chang Xun. At first, because of his favor, he wanted to violate the ancestral training of "heir-long" and canonize Zhu as a prince, which was opposed by the party and had to be canonized as a prince. At this time, a man named Zhang Hui, with a wooden stick in his hand, broke into the Tattoo Palace, the residence of the Prince, and injured the eunuch who was the gatekeeper. When Zhang Qian was tried, the confession was provided by Pang Bao and Liu Cheng, eunuchs of Zheng Guifei. Some people suspect that Zheng Guifei wants to murder the prince. But Zongshen doesn't want to pursue this matter. As a result, Theway was publicly killed for madness. He also secretly killed eunuchs Pang and Liu in the palace, which led to the case.
