Passion Star, a black transgender woman who has served 13 years in men’s prisons, was denied parole last week. The Texas Board of Pardons and Paroles cited the nature of her offense, although her co-defendant — also convicted of aggravated kidnapping and sentenced to 20 years — was released over two years ago. Noting that the co-defendant was white and “not transgender,” Lambda Legal, the group that represents Ms. Star, said it found the disparity a troubling illustration of “the injustice that runs throughout the criminal system.” Ms. Star, 32, was the subject of an article about prison rape in The New York Times; she is suing corrections officials for failing to protect her against sexual victimization.
