Scott White, 51, pleaded guilty in January and could have been charged to life in prison. A coroner in 2017 found a number of assaults, some fatal, where the victims had been targeted because they were thought to be gay. The death of mathematician Scott Johnson was initially called a suicide, but his family pressed for further investigation. An Australian man was killed to 12 years and seven months in prison Tuesday for the 1988 murder of an American who fell off a Sydney cliff that was known as a gay meeting place.
