BREAKING: A federal appeals court halts the execution of Tennessee death row inmate Christa Pike about an hour before she was set to die by lethal injection. Execution witnesses had already gathered at Riverbend Maximum Security Institution in Nashville when the order came down around 9 a.m. local time. The judges say they want to review whether Pike's allegations of childhood sexual abuse and rape were fully considered before she was sentenced to death. Pike, now 50, was convicted of murdering 19-year-old Colleen Slemmer in 1995, when Pike was 18. Her execution would have been Tennessee's first of a woman in at least 200 years. It's not yet clear how long the delay will last or whether Tennessee's attorney general will appeal.
