WASHINGTON, D.C.: Texas executed Wednesday a man who killed a transvestite during a sex game, prison officials said, in a case that drew the attention of Pope Francis. Richard Masterson, 43, who failed in a desperate last-ditch appeal to the US Supreme Court, received a lethal injection and died at 6:53 pm (0053 GMT), a spokesman for the local prison adminstration told AFP. He is the second person executed in the United States this year. Masterson was convicted of strangling to death Darin Honeycutt in 2001 in Houston. Pope Francis, a death penalty opponent, had been closely following the case, said Austrian Cardinal Christoph Schonborn at a press conference Monday. Twenty-eight people were executed in the United States in 2015, according to the non-profit Death Penalty Information Center.
