The sister of a teen murder suspect says she was shocked to learn that she was on her brother's hit list. According to prosecutor interview transcripts, Christina Hernandez broke down in tears as she answered questions about her 14-year-old brother Michael. Michael Hernandez is accused of killing a classmate in the bathroom of a suburban Miami school. Hernandez and victim Jaime Gough took gifted classes together and were best friends. In an AP interview, Hernandez's parents say they noticed their son becoming more aloof -- but chalked it up as typical teen behavior. Hernandez has been charged as an adult and faces life in prison if convicted.
