Besides Aung San, most of his cabinet, and U Saw, there were a number of other assassinations and attempted assassinations carried out against other men who had been close to Aung San at that time. Two of these included Aung San's English lawyer, Frederick Henry, who was murdered in his house, and F. Collins, a private detective who was investigating Aung San's assassination. According to General Kyaw Zaw these murders were evidence that somebody was trying to cover up their involvement in the assassination. In September 1948, nine months after Burma's independence, somebody assassinated Tin Tut, who had been one of Aung San's closest advisors and who at the time was Burma's first foreign minister, by throwing a grenade into his car. The assassins were never caught and nobody was ever charged with his murder. It was rumored that he was investigating Aung San's assassination at the time of his death.
