In April 2011, various intelligence outlets were able to pinpoint bin Laden's suspected location near Abbottabad, Pakistan. It was previously believed that bin Laden was hiding near the border between Afghanistan and Pakistan's Federally Administered Tribal Areas, but he was found 160 km (100 mi) away in a three-story mansion in Abbottabad at 34°10′9.51″N 73°14′32.78″E. Bin Laden's mansion was located 1.3 km (0.8 mi) southwest of the Pakistan Military Academy, the country's "West Point".

Alexander I of Russia
Tsar Alexander I became increasingly suspicious of those around him, especially after an attempt was made to kidnap him when he was on his way to the conference in Aachen, Germany. In the autumn of 1825 the Emperor undertook a voyage to the south of Russia due to the increasing illness of his wife. During his trip he himself caught a cold which developed into typhus from which he died in the southern city of Taganrog on 19 November (O.S.)/ 1 December 1825. His two brothers disputed who would become tsar—each wanted the other to become tsar. Rumours circulated for years that he had not died but had become the monk Feodor Kuzmich. His wife died a few months later as the emperor's body was transported to Saint Petersburg for the funeral. He was interred at the Sts. Peter and Paul Cathedral of the Peter and Paul Fortress in Saint Petersburg on 13 March 1826.
Subhash Chandra Bose
Although it was believed that Netaji Subhash Chandra Bose died in a plane crash, his body was never recovered. There have been many theories put forward regarding his disappearance. The government of India set up a number of committees to investigate the case and come out with truth.
In May 1956, the Shah Nawaz Committee visited Japan to look into the situation of Bose’s assumed death. Citing their lack of political relations with Taiwan, the Centre, did not seek for the assistance from their government.

However, the findings were rejected by the government of India.
