Chapter 31 The Substituted Poison
Mrs. H lived alone after she separated from her doctor husband.But since three days ago, she had a persistent high fever, and the nearby private practitioners did not see her, so she had no choice but to ask her estranged husband to come to see her.

"Don't worry, it's the flu. Get an injection first. If you take this medicine before going to bed tonight, the fever will subside immediately. It will be fine in two or three days." Her husband gave her an injection and left her The next cold medicine in capsules will go back.

That night, before going to bed, she took the cold medicine left by her husband.However, after a few minutes, I suddenly felt uncomfortable, and died soon after.The capsules are actually filled with potassium cyanide.

However, the body was found the next evening.During an autopsy, police found undigested chocolate laced with potassium cyanide remained in his stomach.Therefore, the victim's younger brother was arrested on suspicion of homicide.This is because he had given his sister a box of whiskey bonbons a week earlier.Among them was a piece of chocolate mixed with potassium cyanide.The two siblings were arguing about inheriting the legacy of their deceased father, which shows that they had a murderous motive.However, his brother insisted he was innocent and asked detectives to reopen the investigation.

The detective who investigated the case, after learning that the estranged husband was a physician and was eager to divorce his wife in order to marry a young mistress, investigated his alibi on the night of the crime, and hit the nail on the head. It clearly exposed the doctor's ingenious poisoning method.

So, what method did the doctor use to replace the poisoned capsules eaten by the victim with whiskey bonbons?

[Answer] is to use a gastric straw.After his wife died after eating poisonous cold medicine, the doctor sneaked back and inserted a medical suction catheter into the deceased's stomach to suck out the dissolved capsules and potassium cyanide.And, in the same way, the whiskey liqueur chocolate was tempered with warm water and injected into the stomach of the deceased.Of course, the whiskey bonbon solution was also mixed with potassium cyanide.In this way, even if the stomach of the corpse was dissected, only undigested whiskey bonbons remained in it, so it was mistaken for death by eating bonbons mixed with potassium cyanide.
