Christa Gail Pike was just 18 years old when she committed a crime that dominated headlines for years: She tortured and murdered her romantic rival in Tennessee and later showed off a piece of the 19-year-old woman's skull to schoolmates.The killing in the woods of Knoxville demonstrated a brutality and callousness rarely seen in a woman, let alone one so young. Pike is set to be executed by lethal injection about six months from now on Sept. 30. If the execution moves forward, Pike will be the first woman put to death in Tennessee in more than 200 years and only the 19th woman executed in modern U.S. history. Do you think Christa Pike deserve the death penalty for her heinous crime?
