The South Dakota Supreme court has denied convicted killer Eric Robert's request for a quick execution.
Robert was sentenced to death for his role in the death of Corrections Officer Ron "RJ" Johnson during a prison escape attempt last April.
The original execution was scheduled for May. But because of a mandatory review by the South Dakota Supreme Court to determine the sentence is appropriate, the execution could be delayed for up to two years.
But the Supreme Court on Thursday ruled unanimously that it wouldn't make sense for Robert to die of lethal injection before the justices determine if the death penalty is proper.
