A US trafficking victim serving a life sentence for killing a man who bought her for sex when she was a teenager was granted clemency Monday following a celebrity-backed viral campaign for her freedom. Tennessee Governor Bill Haslam said Cyntoia Brown, now 30, had been given “too harsh” a sentence for the 2004 murder of a real estate agent in the city of Nashville. Johnny Allen had picked up Brown, who was 16 at the time and a runaway under the influence of a dangerous pimp, and taken her to his home for sex.
