The answer is here. 1. There is cyanide reaction in the soup. There is no poison reaction in the steamed bun slices. Most of them have traces of being immersed in the soup. The deceased's habit of eating steamed bread slices was obviously to dip them in soup. But why is the soup poisonous but the steamed bread slices are not? Other items related to food also have no cyanide reaction 2. There was undigested food in the stomach of the deceased, but no poison remained. 3. No one had entered the deceased’s room before his death. 4 1 2 3 The conclusion is that the soup was not poisonous before the death of the deceased. 5. If 4 is not true, the poison in the soup has already existed. The deceased took more than one mouthful of the soup, as evidenced by the slices of steamed buns. Then the steamed bun slices should be poisonous, which is inconsistent with the facts. Therefore, four is established. 6. There was a smell of cyanide in the mouth of the deceased. Seven Four Six The conclusion is that the poison of the deceased came from other items put into the mouth, which can only be cigarettes. 8 Another conclusion drawn from 4 is that the poison in the soup was administered after the death of the deceased. 9. The only person who has the opportunity to poison is Go call the police ヾら ひ ㄣ亻 ニ ^ヾ 匸 This is how he committed the crime 1.

It was he who introduced the drug dealer to the deceased. 3. On the day the drug dealer came, he prepared a box of cigarettes that the deceased often smoked. There was a filter inside with cyanide in it. 4. Changing cigarettes while playing chess with the deceased 5. After the drug dealer leaves, call the deceased at the appropriate time. 6. The purpose of making long phone calls was to monitor when the deceased would die, and then immediately come to the deceased’s home. 7.
