The FBI has been called in to investigate the hanging death of a young, black woman in a Texas jail. The official cause is "suicide," but her family finds that incomprehensible. On Friday afternoon, Sandra Bland had just accepted a new job at her alma mater, Prairie View A&M in Waller County, Texas. On the road, she was stopped by a state trooper for failing to signal while changing lanes. Police say she became combative, and she was taken to jail. Monday morning, she was found hung from a noose made with a trash bag in her cell. State legislators are demanding answers.
