5 The death of German youth, Kaspar Hauser, is still a mystery. On 14 December 1833, he came home with a stab wound in his chest and died three days later. He claimed to have been attacked, but the court of inquiry doubted this and speculated that he wounded himself to seek attention.

However, many claims made by Hauser were inconsistent and this led the Ansbach Court of Inquiry to assume that he stabbed himself to gain attention.

6 Zachary Taylor, the 12th president of the US, died on 9 July 1850. Doctors reported cholera morbus as the reason for death, but rumors circulated that pro-slavery Southerners poisoned him.

Zachary Taylor, the 12th president of the US who was also the American military leader, died on 9 July 1850 at the age of 65.

Taylor was an officer in the United States Army, was promoted to the rank of major general, and became the national hero after his victories in the Mexican–American War. However, his death caused much controversy. It was suggested that he was assassinated.

The doctors blamed cholera morbus as the reason for death, but it is said that pro-slavery Southerners poisoned him, or the 13th US president, Millard Fillmore, poisoned him. Millard Fillmore proposed many new laws, but Taylor opposed them, and Millard Fillmore was sworn in the next day after Taylor’s death.

However, there was only a small amount of arsenic present, and it was not enough to prove the assassination. Hence, his death mystery remained unsolved. (1, 2)
