Executive Director Olivia Craven tells The Lewiston Tribune ( http://bit.ly/1b2yhW7) the commission met Thursday and reversed its October ruling based on "a procedural error." She declined to say what the error was.
The ruling means Lankford won't be eligible to appear before the parole board again until January 2019.
Lankford is serving a life sentence for the 1984 murders of U.S. Marine Capt. Robert Bravence and his wife, Cheryl, of El Paso, Texas. The couple were killed while they were camping in Idaho.
Lankford and his brother, Mark, were both convicted and initially sentenced to death. They are both now serving life sentences.
