Robert Roberson was scheduled to be executed on Thursday for the murder of his own daughter – but received a last-minute reprieve amid widespread concerns that she died of natural causes

Roberson was scheduled to be executed last Thursday for the 2002 killing of his 2-year-old daughter Nikki Curtis – who allegedly died from shaken baby syndrome – a crime he and his advocates say did not happen.
