After three young men were charged with the murder of John Denley Nelson yesterday, a fourth Singaporean man has also been added to the list of people accused of causing his death in a bar fight. 42-year-old Masazlie Mohamed Salleh originally had been charged with rioting, but his charge was amended to murder today, The Straits Times reports. He joins Muhammad Khalis Ramlee, Muhammad Haziq Hashim and Muhammad Izzuandy Yusof — all aged 23 — as the group of people accused of causing the 30-year-old American national's death.
